Planting it in damp conditions can cause winter leaf drop, which likely explains why kōhūhū is not found growing on the West Coast of New Zealand. In its role in ecological succession, kōhūhū is often found at an earlier stage than its relative lemonwood (another endemic "Pittosporum"), and usually inhabits less fertile soils.## Predators, Parasites, and Diseases.## Insects.There are over 50 insect species listed in the Plant-SyNZ database that either feed on or parasitise kōhūhū – wasps, sucking bugs, flies, moths, butterflies, thrips, mites and beetles.

Shaft sinking. Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means.Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve.

Shaft sinking. of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa.The modern shaft sinking industry is gradually shifting further towards greater mechanisation, recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have shown promise but the use of this method is, as of 2019, not widespread.## Mine shafts.Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during of the development of an underground mine.The shape (in plan view), dimensions and depth of mine shafts vary greatly.

Shaft sinking. in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. Larger shafts are round in plan and are concrete lined.Mine shafts may be used for a variety of purposes, including as a means of escape in the event of an emergency underground and allowing for the movement of: People Materials Mine services (such as compressed air, water, backfill, power, communications and fuel) Ventilation air Broken rock (in the form of.

Shaft sinking. payable ore, or non payable waste) Or any combination of the aboveWhen the top of the excavation is the ground surface, it is referred to as a "shaft"; when the top of the excavation is underground, it is called a "winze" or a "sub-shaft". Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called "raises".A shaft may be either vertical or inclined (between 80 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of.

Shaft sinking. the proposed shaft, and ground conditions allow, then raise boring may be used to excavate the shaft from the bottom up; such shafts are called "borehole shafts".Following the Hartley Colliery disaster where the single shaft at the mine became blocked, the United Kingdom made single shaft mines illegal in 1862, establishing the practice that all underground mines must have a "a second means of egress". Many other global mining jurisdictions have adopted this rule and shafts are therefore often found in pairs (although there are multiple alternative methods of providing a second means of egress).The current the deepest single lift.

Shaft sinking. (i.e. continuous) mine shaft in the world is the 2991m deep, main shaft at South Deep Mine in South Africa, owned by Gold Fields Limited, which, along with its twin ventilation shafts, took ten years to sink and equip.## Parts of a mine shaft.The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist (or winder) used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).

Shaft sinking. The headframe will also typically contain bins for storing ore being transferred to the processing facility.At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out.

Shaft sinking. of the mine.Beneath the collar the part of the shaft which continues into the ground is called the "shaft barrel".At locations where the shaft barrel meets horizontal workings there is a "shaft station" (or inset) which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest shaft station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a "loading pocket" is excavated on one side of the shaft at this.

Shaft sinking. location to allow transfer facilities to be built.Beneath the lowest shaft station the shaft continues on for some distance, this area is referred to as the "shaft bottom". A tunnel called a "ramp" typically connects the bottom of the shaft with the rest of the mine, this ramp often contains the mine's water handling facility, called the "sump", as water will naturally flow to the lowest point in the mine.## Shaft lining.Many (although not all) shafts are lined following excavation and the installation of temporary ground support.The shaft lining performs several functions; it is first and foremost a safety feature.

Shaft sinking. preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into, and lastly a smooth surface to minimise resistance to airflow for ventilation.Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind "shaft forms" in.

Shaft sinking. lifts of 6 m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, and precast concrete segments have all been used at one time or another. Additionally, the use of materials like bitumen and even squash balls have been required by specific circumstances. In extreme cases, particularly when sinking through halite, composite liners consisting of two or more materials may be required.The shaft liner does not reach right to the bottom of the shaft during sinking, but lags behind by a fixed distance. This distance is determined by the methodology of excavation and the design thickness of the.

Shaft sinking. permanent liner. To ensure the safety of persons working on the shaft bottom temporary ground support is installed, usually consisting of welded mesh and rock bolts. The installation of the temporary ground support (called "bolting") is among the most physically challenging parts of the shaft sinking cycle as bolts must be installed using pneumatic powered rock drills.For this reason, and to minimise the number of persons on the shaft bottom a number of projects have successfully switched to shotcrete for this temporary lining. Research and development in this area is focusing on the robotic application of shotcrete and the commercialisation.

Shaft sinking. of thin sprayed polymer liners.## Shaft compartments.Where the shaft is to be used for hoisting it is frequently split into multiple compartments by "shaft sets", these may be made of either timber or steel. Vertical members in a shaft set are called "guides", horizontal members are called "buntons". For steel shaft guides, the main two options are hollow structural sections and top hat sections. Top hat sections offer a number of advantages over hollow structural sections including simpler installation, improved corrosion resistance and increased stiffness. Mine conveyances run on the guides in a similar way to how a steel roller.

Shaft sinking. coaster runs on its rails, both having wheels which keep them securely in place.Some shafts do not use guide beams but instead utilize steel wire rope (called "guide rope") kept in tension by massive weights at shaft bottom called "cheese weights" (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace.The largest compartment is typically used for the "mine cage", a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator. Cages.

Shaft sinking. may be single-, double-, or rarely triple-deck, always having multiple redundant safety systems in case of unexpected failure.The second compartment is used for one or more skips, used to hoist ore to the surface. Smaller mining operations use a skip mounted underneath the cage, rather than a separate device, while some large mines have separate shafts for the cage and skips. The third compartment is used for an emergency exit; it may house an auxiliary cage or a system of ladders. An additional compartment houses mine services such as high voltage cables and pipes for transfer of water, compressed air.

Shaft sinking. or diesel fuel.A second reason to divide the shaft is for ventilation. One or more of the compartments discussed above may be used for air intake, while others may be used for exhaust. Where this is the case a steel or concrete wall called a "brattice" is installed between the two compartments to separate the air flow. At many mines there are one or more complete additional separate "auxiliary shafts" with separate head gear and cages.## Shaft construction.The lowest point in a sinking shaft is known as "shaft bottom", shaft projects differ from some other forms of mine development in.

Shaft sinking. that all activities that take place on shaft bottom become part of the critical path for the project schedule. The infrastructure required to sink a shaft is referred to a "the sinking set-up".It is typical for progress (the "sinking rate") in the sinking phase (that is excavation, ground support and lining) of a shaft project to follow a learning curve as the project team repeat the same series of activities over and over in what is called "the sinking cycle", eventually approaching the theoretical maximum rate for that sinking set up over time. The use of experienced shaft sinkers is.

Shaft sinking. necessary to reduce the length of this learning curve and thus the duration of the project as much as possible.Key to a successful shaft sinking project are: Getting the various components of the sinking set-up correct and installed at the right time. Having experienced people involved from as early in the project as possible Using the available time on shaft bottom as efficiently as possible.Although significant emphasis is placed on the rate of progress of a project sinking cycle by shaft sinkers, sinking is only one of a number of phases in the conventional construction of a new shaft, as.

Shaft sinking. follows; "Box Cut Excavation". A box cut is a large square or rectangular excavation typically completed using earthmoving equipment down to bedrock, inside which the shaft collar will be constructed. Having the loads imposed by the collar, headframe and hoisting plant transferred into solid rock is necessary to prevent unplanned subsidence. Where the depth of bedrock is to great to for a box cut to economically viable, or the bedrock is not strong enough, civil engineering techniques such as diaphragm walls or concrete piles may be used to create a deep foundation instead. "Pre-Sink". The pre-sink is the excavation and.

Shaft sinking. support of the first 60 – 100 meters of the shaft barrel, often completed smaller equipment such as handheld, pneumatic drilling equipment to drill holes for basting and ground support and mini-excavators for mucking. During the pre-sink hoisting of muck and equipment is usually performed by a mobile crane on surface. It is necessary to sink this part of the shaft first so that the Galloway, a multi-level working platform may be installed with enough vertical distance to shaft bottom that it will not be damaged by fly rock during blasting. "Collar Construction". From the bottom of the box-cut, the.

Shaft sinking. shaft collar is constructed bottom up in a planned series of concrete pours. "Galloway (Sinking Stage) Construction & Installation." The Galloway (also known as a Sinking Stage or Scaffold) is a multi-level working platform, suspended in the shaft from winches located on surface. The Galloway allows sinkers to efficiently work on differing levels as required by the various tasks of the sinking cycle. It is typical for the Galloway to be constructed off to one side of the shaft and lowered into the pre-sink with a crane in as complete a state as possible. Once in place the Galloway is.

Shaft sinking. "chaired" (suspended from the shaft collar) while the headframe is built above, often protected by a bulkhead. "Headframe & Hoist House Construction." With the collar constructed and the Galloway installed the headframe and hoist (or winder) houses may be constructed and the hoist and winch ropes installed. Headframes may be either steel or concrete and their design will determine how they are constructed. The Galloway is moved in the shaft by means of winches, which move slowly and are rated for significant loads, while the sinking buckets (or kibbles) are moved in the shaft by the sinking hoist, which moves.

Shaft sinking. quickly and is rates for less load that the winches. To protect the hoist(s) and winches and the sensitive electronics which are used to control their operation they are normally installed inside of a build called a hoist (or winder) house. "Commissioning Sinking Set Up." The Sinking set-up must then be commissioned to ensure that all parts are operating as planned. "Full Sink". The activities of the sinking cycle (excavation, installation of temporary ground support, placement of the shaft lining and extending shaft services) all take place in this phase of construction. In a shaft where there are to be.

Shaft sinking. multiple working levels, shaft stations and station stubs (short lengths of horizontal tunnel leading away from the station) will be developed by the sinkers on the way down. As the equipment to excavate these stations must be small enough to fit through the openings in the Galloway, the rate of advance in developing the station stubs is typically low, compared to what can be achieved with full size mining equipment so station stubs are typically kept as short as possible. "Shaft Equipping & Headframe Changeover." Once the shaft reaches the final design depth, the shaft is stripped of any temporary.

Shaft sinking. services, the Galloway cut up or modified to suit the installation of the permanent shaft set-up, the shaft sets (if required) installed and the headframe / winders modified to allow for permanent hoisting. Any permanent conveyances will be installed at this stage. "Commissioning Permanent Set Up." The Permanent set-up must then be commissioned to ensure that all parts are operating as planned before being handed over to the new owner.As with the depth and design of shafts significant variations do exist in this sequence depending on local conditions, for example in that hard Canadian Shield rocks which dominate shaft sinking.

Shaft sinking. in Canada a deep and complex shaft collar is unnecessary as the bedrock is both strong and close to surface. This reduces the amount of time typically required to establish the shaft collar.Traditionally sinking contractors would build a temporary headframe for the sinking set up, which would then be dismantled to make way for a permanent headframe. With the growth in complexity and duration of shaft sinking projects over time it has become more common to incorporate more of the permanent shaft set-up into the sinking phase. This results in a reduced overall project duration, as for example, if the.

Shaft sinking. service piping used to sink the shaft does not need to be stripped out to make way for permanent piping.With the advancements made in raise boring technology, raise borers have been used to create a pilot hole for shaft sinking, where access exists at the bottom of the new shaft, in this case the sinking phase is dedicated to enlarging this pilot hole to full diameter (a process usually called "slashing"). This methodology can be considerably faster than full face sinking as muck (waste rock) from sinking falls down the pilot hole and is handled using existing mine infrastructure off.

Walrus. Norse word ('horse'). For example, the Old Norse word means 'horse-whale' and is thought to have been passed in an inverted form to both Dutch and the dialects of northern Germany as and . An alternative theory is that it comes from the Dutch words 'shore' and 'giant'.The species name "rosmarus" is Scandinavian. The Norwegian manuscript "Konungs skuggsjá", thought to date from around AD 1240, refers to the walrus as in Iceland and in Greenland (walruses were by now extinct in Iceland and Norway, while the word evolved in Greenland). Several place names in Iceland, Greenland and Norway may originate.

Walrus. Tusks and dentition.While this was not true of all extinct walruses, the most prominent feature of the living species is its long tusks. These are elongated canines, which are present in both male and female walruses and can reach a length of 1 m (3 ft 3 in) and weigh up to 5.4 kg (12 lb). Tusks are slightly longer and thicker among males, which use them for fighting, dominance and display; the strongest males with the largest tusks typically dominate social groups. Tusks are also used to form and maintain holes in the ice and aid the walrus in.

Walrus. Vibrissae (whiskers).Surrounding the tusks is a broad mat of stiff bristles ("mystacial vibrissae"), giving the walrus a characteristic whiskered appearance. There can be 400 to 700 vibrissae in 13 to 15 rows reaching 30 cm (12 in) in length, though in the wild they are often worn to much shorter lengths due to constant use in foraging. The vibrissae are attached to muscles and are supplied with blood and nerves, making them highly sensitive organs capable of differentiating shapes 3 (mm) thick and 2 (mm) wide.## Skin.Aside from the vibrissae, the walrus is sparsely covered with fur and appears bald.

Walrus. walrus numbers have again declined. Early aerial censuses of Pacific walrus conducted at five-year intervals between 1975 and 1985 estimated populations of above 220,000 in each of the three surveys.In 2006, the population of the Pacific walrus was estimated to be around 129,000 on the basis of an aerial census combined with satellite tracking. There were roughly 200,000 Pacific walruses in 1990.The much smaller population of Atlantic walruses ranges from the Canadian Arctic, across Greenland, Svalbard, and the western part of Arctic Russia. There are eight hypothetical subpopulations of Atlantic walruses, based largely on their geographical distribution and movements: five.

Walrus. A genetically distinct population existed in Iceland that was wiped out after Norse settlement around 1213–1330 AD.The isolated population of Laptev Sea walruses is confined year-round to the central and western regions of the Laptev Sea, the eastmost regions of the Kara Sea, and the westmost regions of the East Siberian Sea. The current population of these walruses has been estimated to be between 5,000 and 10,000.Even though walruses can dive to depths beyond 500 meters, they spend most of their time in shallow waters (and the nearby ice floes) hunting for food.In March 2021, a single walrus, nicknamed Wally.

Walrus. while giving birth and aggregating in the reproductive period. Thinner pack ice over the Bering Sea has reduced the amount of resting habitat near optimal feeding grounds. This more widely separates lactating females from their calves, increasing nutritional stress for the young and lower reproductive rates. Reduced coastal sea ice has also been implicated in the increase of stampeding deaths crowding the shorelines of the Chukchi Sea between eastern Russia and western Alaska. Analysis of trends in ice cover published in 2012 indicate that Pacific walrus populations are likely to continue to decline for the foreseeable future, and shift further.

Walrus. the Inuit goddess Sedna. Both in Chukotka and Alaska, the aurora borealis is believed to be a special world inhabited by those who died by violence, the changing rays representing deceased souls playing ball with a walrus head.Most of the distinctive 12th-century Lewis Chessmen from northern Europe are carved from walrus ivory, though a few have been found to be made of whales' teeth.## Literature.Because of its distinctive appearance, great bulk, and immediately recognizable whiskers and tusks, the walrus also appears in the popular cultures of peoples with little direct experience with the animal, particularly in English children's literature.

Black-footed ferret. The black-footed ferret (Mustela nigripes), also known as the American polecat or prairie dog hunter, is a species of mustelid native to central North America.The black-footed ferret is roughly the size of a mink and is similar in appearance to the European polecat and the Asian steppe polecat. It is largely nocturnal and solitary, except when breeding or raising litters. Up to 90% of its diet is composed of prairie dogs.The species declined throughout the 20th century, primarily as a result of decreases in prairie dog populations and sylvatic plague. It was declared extinct in 1979, but a residual wild.

Buchlovice Castle. Buchlovice Castle () is a chateau in Buchlovice in the Zlín Region of the Czech Republic. Its history is closely connected with nearby Buchlov Castle which grew more and more uncomfortable in the late 17th century, and that is why Jan Dětřich of Petřwald decided to build a new castle. Buchlovice Castle was built as a copy of an Italian villa in baroque style, by Domenico Martinelli. It is one of the most romantic buildings in this country. In 1800 it became property of the Berchtolds, and since 1945 the state castle is open to the public.## History.The area around.

Alarm device. An alarm device is a mechanism that gives an audible, visual or other kind of alarm signal to alert someone to a problem or condition that requires urgent attention.## Etymology.The word "alarm" comes from the Old French "a l'arme" meaning "to the arms", or "to the weapons", telling armed men to pick up their weapons and get ready for action because an enemy may have suddenly appeared.The word "alarum" is an archaic form of "alarm". It was sometimes used as a call to arms in the stage directions of Elizabethan dramas. The term comes from the Italian "all'armi" and appears.

Alarm device. either case. A person in such a state can be characterized as "alarmed".## False alarms.With any kind of alarm, you must balance between the danger of false alarms (called "false positives") — the signal going off in the absence of a problem — or an alarm failing to signal an actual problem (called a "false negative"). False alarms can waste resources expensively and can even be dangerous. For example, false alarms of a fire can waste firefighter manpower, making them unavailable for a real fire, and risk injury to firefighters and others as the fire engines race to the alleged.

Alarm device. fire's location. In addition, false alarms may acclimatise people to ignore alarm signals, and thus possibly to ignore an actual emergency: Aesop's fable of "The Boy Who Cried Wolf" exemplifies this problem.A false alarm is one of the most significant issues with conventional alarm systems. They can be triggered for several reasons, such as the movement of pets, typing in the wrong security codes, or loud sounds from windows or doors. In the case of fire alarms, aerosol sprays, smoking, or burning food can all lead to a false alarm.Many avoid the risk of false alarms by ensuring their alarms.

Tuning fork. A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out. A tuning fork's pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments.The tuning fork was invented in 1711 by British musician John Shore, Sergeant trumpeter and lutenist.

Tuning fork. John Shore gave to George Frideric Handel produces C=512.Tuning forks, usually C512, are used by medical practitioners to assess a patient's hearing. This is most commonly done with two exams called the Weber test and Rinne test, respectively. Lower-pitched ones, usually at C128, are also used to check vibration sense as part of the examination of the peripheral nervous system.Orthopedic surgeons have explored using a tuning fork (lowest frequency C=128) to assess injuries where bone fracture is suspected. They hold the end of the vibrating fork on the skin above the suspected fracture, progressively closer to the suspected fracture. If.

Anderton Boat Lift. The Anderton Boat Lift is a two caisson lift lock near the village of Anderton, Cheshire, in North West England. It provides a 50 (ft) vertical link between two navigable waterways: the River Weaver and the Trent and Mersey Canal. The structure is designated as a scheduled monument, and is included in the National Heritage List for England; it is also known as one of the Seven Wonders of the Waterways.Built in 1875, the boat lift was in use for over 100 years until it was closed in 1983 due to corrosion. Restoration started in 2001 and the boat lift.

Anderton Boat Lift. was re-opened in 2002. The lift and associated visitor centre and exhibition are operated by the Canal & River Trust. It is one of only two working boat lifts in the United Kingdom; the other is the Falkirk Wheel in Scotland.## Economic background.Salt has been extracted from rock salt beds underneath the Cheshire Plain since Roman times. By the end of the 17th century a major salt mining industry had developed around the Cheshire "salt towns" of Northwich, Middlewich, Nantwich and Winsford.Completion of the River Weaver Navigation in 1734 provided a navigable route for transporting salt from Winsford, through Northwich,.

In 1759 the second Weaver Navigation Act appointed the Trustees of the Weaver Navigation and gave them responsibility for maintaining and operating the route. The opening of the Trent and Mersey Canal in 1777 provided a second route close to the Weaver Navigation for part of its length, but extended further south to the coal mining and pottery industries around Stoke-on-Trent.Rather than competing with each other the owners of the two waterways decided it would be more profitable to work together. In 1793 a basin was excavated on the north bank.

When this approach was unsuccessful the Trustees decided to fund the project themselves.The Trustees asked their Chief Engineer, Edward Leader Williams, to draw up plans for a boat lift. He settled on a design involving a pair of water-filled caissons that would counterbalance one another and require relatively little power to lift boats up and down. A similar boat lift on the Grand Western Canal, completed in 1835, used chains to connect the caissons via an overhead balance wheel. It had a solid masonry superstructure.

It was completed in December 2003 and opened in April 2004. With 41 floors, it is 180 (m) tall and stands on the sites of the former Baltic Exchange and Chamber of Shipping, which were extensively damaged in 1992 in the Baltic Exchange bombing by a device placed by the Provisional IRA in St Mary Axe, a narrow street leading north from Leadenhall Street.After plans to build the 92-storey Millennium.

Elephant. in size led to the development and elongation of the mobile trunk to provide reach. The number of premolars, incisors and canines decreased.The cheek teeth (molars and premolars) of proboscideans became larger and more specialized, especially after elephants started to switch from C3-plants to C4-grasses, which caused their teeth to undergo a three-fold increase in teeth height as well as substantial multiplication of lamellae after about five million years ago. Only in the last million years or so did they return to a diet mainly consisting of C3 trees and shrubs. The upper second incisors grew into tusks, which varied.

Elephant. develop gigantism in these conditions. Dwarf elephants are known to have lived in Indonesia, the Channel Islands of California, and several islands of the Mediterranean.## Anatomy.## Size.Elephants are the largest living terrestrial animals. African bush elephants are the largest species, with males being 304 - 336 (cm) tall at the shoulder with a body mass of 5.2 - 6.9 (MT) and females standing 247 - 273 (cm) tall at the shoulder with a body mass of 2.6 - 3.5 (MT).

Individuals may show lateral preference when grasping with their trunks: some prefer to twist them to the left, others to the right. Elephants are capable of dilating their nostrils at a radius of nearly 30%, increasing the nasal volume by 64%, and can inhale at over 150 (m/s) which is around 30 times the speed of a human sneeze. Elephants can suck up food and water both to.

Elephant. teeth falls out at four to six years old. The third set falls out at 9–15 years of age and set four lasts until 18–28 years of age. The fifth set of teeth falls out at the early 40s. The sixth (and usually final) set must last the elephant the rest of its life. Elephant teeth have loop-shaped dental ridges, which are thicker and more diamond-shaped in African elephants.## Tusks.The tusks of an elephant are modified second incisors in the upper jaw. They replace deciduous milk teeth at 6–12 months of age and grow continuously at about 17 (cm) a.

Elephant. well into a gallop, even accounting for leg length. Spring-like kinetics could explain the difference between the motion of elephants and other animals. During locomotion, the cushion pads expand and contract, and reduce both the pain and noise that would come from a very heavy animal moving. Elephants are capable swimmers. They have been recorded swimming for up to six hours without touching the bottom, and have swum as far as 48 (km) at a stretch and at speeds of up to 2.1 (km/h).## Organs.The brain of an elephant weighs 4.5 – 5.5 (kg) compared to 1.6 (kg) for a.

Elephant. human brain. It is the largest of all terrestrial mammals. While the elephant brain is larger overall, it is proportionally smaller than the human brain when compared to their size. At birth, an elephant's brain already weighs 30–40% of its adult weight. The cerebrum and cerebellum are well developed, and the temporal lobes are so large that they bulge out laterally. Their temporal lobes are proportionally larger than in other animals, including humans. The throat of an elephant appears to contain a pouch where it can store water for later use. The larynx of the elephant is the largest known.

Elephant. among mammals. The vocal folds are long and are attached close to the epiglottis base. When comparing an elephant's vocal folds to those of a human, an elephant's are longer, thicker, and have a larger cross-sectional area. In addition, they are tilted at 45 degrees and positioned more anteriorly than a human's vocal folds.The heart of an elephant weighs 12 – 21 (kg). It has a double-pointed apex, an unusual trait among mammals. In addition, the ventricles separate near the top of the heart, a trait they share with sirenians. When standing, the elephant's heart beats approximately 30 times per.

Elephant. fully erect and has a Y-shaped orifice. The female has a well-developed clitoris at up to 40 (cm). The vulva is located between the hind legs instead of near the tail as in most mammals. Determining pregnancy status can be difficult due to the animal's large abdominal cavity. The female's mammary glands occupy the space between the front legs, which puts the suckling calf within reach of the female's trunk. Elephants have a unique organ, the temporal gland, located in both sides of the head. This organ is associated with sexual behaviour, and males secrete a fluid from it when.

Elephant. and will eat leaves, twigs, fruit, bark, grass and roots. They are born with sterile intestines and require bacteria obtained from their mother's feces to digest vegetation. African elephants are mostly browsers while Asian elephants are mainly grazers. They can consume as much as 150 (kg) of food and 40 (L) of water in a day. Elephants tend to stay near water sources. Major feeding bouts take place in the morning, afternoon and night. At midday, elephants rest under trees and may doze off while standing. Sleeping occurs at night while the animal is lying down. Elephants average 3–4 hours.

Elephant. he matures, a male spends more time at the edge of his group and associates with outside males or even other families. At Amboseli, young males spend over 80% of their time away from their families when they are 14–15. When males permanently leave, they either live alone or with other males. The former is typical of bulls in dense forests. Asian males are usually solitary, but occasionally form groups of two or more individuals; the largest consisted of seven bulls. Larger bull groups consisting of over 10 members occur only among African bush elephants, the largest of which numbered.

Elephant. up to 144 individuals. Bulls only return to the herd to breed or to socialize, they do not provide prenatal care to their offspring but rather play a fatherly role to younger bulls to show dominance.Male elephants can be quite sociable when not competing for dominance or mates, and will form long-term relationships. A dominance hierarchy exists among males, whether they range socially or solitarily. Dominance depends on the age, size and sexual condition, and when in groups, males follow the lead of the dominant bull. Young bulls may seek out the company and leadership of older, more experienced males,.

Elephant. whose presence appears to control their aggression and prevent them from exhibiting "deviant" behaviour. Adult males and females come together for reproduction. Bulls associate with family groups if an oestrous cow is present.## Sexual behaviour.## Musth.Adult males enter a state of increased testosterone known as musth. In a population in southern India, males first enter musth at the age of 15, but it is not very intense until they are older than 25. At Amboseli, bulls under 24 do not go into musth, while half of those aged 25–35 and all those over 35 do. Young bulls appear to enter.

Elephant. season. A cow in oestrus releases chemical signals (pheromones) in her urine and vaginal secretions to signal her readiness to mate. A bull will follow a potential mate and assess her condition with the flehmen response, which requires the male to collect a chemical sample with his trunk and bring it to the vomeronasal organ. The oestrous cycle of a cow lasts 14–16 weeks with a 4–6-week follicular phase and an 8- to 10-week luteal phase. While most mammals have one surge of luteinizing hormone during the follicular phase, elephants have two. The first (or anovulatory) surge, could signal to.

Elephant. males that the female is in oestrus by changing her scent, but ovulation does not occur until the second (or ovulatory) surge. Fertility rates in cows decline around 45–50 years of age.Bulls engage in a behaviour known as mate-guarding, where they follow oestrous females and defend them from other males. Most mate-guarding is done by musth males, and females actively seek to be guarded by them, particularly older ones. Thus these bulls have more reproductive success. Musth appears to signal to females the condition of the male, as weak or injured males do not have normal musths. For young females,.

Elephant. the approach of an older bull can be intimidating, so her relatives stay nearby to provide support and reassurance. During copulation, the male lays his trunk over the female's back. The penis is very mobile, being able to move independently of the pelvis. Before mounting, it curves forward and upward. Copulation lasts about 45 seconds and does not involve pelvic thrusting or ejaculatory pause. Elephant sperm must swim close to 2 (m) to reach the egg. By comparison, human sperm has to swim around only 76.2 (mm).Homosexual behaviour is frequent in both sexes. As in heterosexual interactions, this involves mounting.

Elephant. to groom, drink, and feed itself are fully developed. It still needs its mother for nutrition and protection from predators for at least another year. Suckling bouts tend to last 2–4 min/hr for a calf younger than a year and it continues to suckle until it reaches three years of age or older. Suckling after two years may serve to maintain growth rate, body condition and reproductive ability.Play behaviour in calves differs between the sexes; females run or chase each other while males play-fight. The former are sexually mature by the age of nine years while the latter become mature.

Elephant. around 14–15 years. Adulthood starts at about 18 years of age in both sexes. Elephants have long lifespans, reaching 60–70 years of age. Lin Wang, a captive male Asian elephant, lived for 86 years.## Communication.Touching is an important form of communication among elephants. Individuals greet each other by stroking or wrapping their trunks; the latter also occurs during mild competition. Older elephants use trunk-slaps, kicks, and shoves to discipline younger ones. Individuals of any age and sex will touch each other's mouths, temporal glands, and genitals, particularly during meetings or when excited. This allows individuals to pick up chemical cues.

Elephant. vegetation. They are usually bluffing when performing these actions. Excited elephants may raise their trunks. Submissive ones will lower their heads and trunks, as well as flatten their ears against their necks, while those that accept a challenge will position their ears in a V shape.Elephants produce several vocalisations, usually through the larynx, though some may be modified by the trunk. These include trumpets, roars, barks, snorts, growls and rumbles which may be produced for either short or long range communication. Elephants may produce infrasonic rumbles. For Asian elephants, these calls have a frequency of 14–24 Hz, with sound pressure.

Elephant. in Central Africa, 110,000 in eastern Africa, 204,000 in southern Africa, and 19,000 in western Africa. About 214,000 elephants were estimated to live in the rainforests, fewer than had previously been thought. From 1977 to 1989, elephant populations declined by 74% in East Africa. After 1987, losses in elephant numbers accelerated, and savannah populations from Cameroon to Somalia experienced a decline of 80%. African forest elephants had a total loss of 43%. Population trends in southern Africa were mixed, with anecdotal reports of losses in Zambia, Mozambique and Angola while populations grew in Botswana and Zimbabwe and were stable in.

Elephant. South Africa. Conversely, studies in 2005 and 2007 found populations in eastern and southern Africa were increasing by an average annual rate of 4.0%. The IUCN estimated that total population in Africa is estimated at around to 415,000 individuals for both species combined as of 2016.African elephants receive at least some legal protection in every country where they are found, but 70% of their range exists outside protected areas. Successful conservation efforts in certain areas have led to high population densities. As of 2008, local numbers were controlled by contraception or translocation. Large-scale cullings ceased in 1988 when Zimbabwe abandoned.

Elephant. be around 40,000–50,000, although this may be a loose estimate. Around 60% of the population is in India. Although Asian elephants are declining in numbers overall, particularly in Southeast Asia, the population in the Western Ghats appears to be increasing.## Threats.The poaching of elephants for their ivory, meat and hides has been one of the major threats to their existence. Historically, numerous cultures made ornaments and other works of art from elephant ivory, and its use rivalled that of gold. The ivory trade contributed to the African elephant population decline in the late 20th century. This prompted international bans on.

Elephant. riding on them or to pin the soldier to the ground and impale him.One of the earliest references to war elephants is in the Indian epic "Mahabharata" (written in the 4th century BC, but said to describe events between the 11th and 8th centuries BC). They were not used as much as horse-drawn chariots by either the Pandavas or Kauravas. During the Magadha Kingdom (which began in the 6th century BC), elephants began to achieve greater cultural importance than horses, and later Indian kingdoms used war elephants extensively; 3,000 of them were used in the Nandas (5th and 4th centuries.

Elephant. BC) army while 9,000 may have been used in the Mauryan army (between the 4th and 2nd centuries BC). The "Arthashastra" (written around 300 BC) advised the Mauryan government to reserve some forests for wild elephants for use in the army, and to execute anyone who killed them. From South Asia, the use of elephants in warfare spread west to Persia and east to Southeast Asia. The Persians used them during the Achaemenid Empire (between the 6th and 4th centuries BC) while Southeast Asian states first used war elephants possibly as early as the 5th century BC and continued to.

Elephant. an overabundance of the animals.Keeping elephants in zoos has met with some controversy. Proponents of zoos argue that they offer researchers easy access to the animals and provide money and expertise for preserving their natural habitats, as well as safekeeping for the species. Critics claim that the animals in zoos are under physical and mental stress. Elephants have been recorded displaying stereotypical behaviours in the form of swaying back and forth, trunk swaying, or route tracing. This has been observed in 54% of individuals in UK zoos. Elephants in European zoos appear to have shorter lifespans than their wild counterparts.

Elephant. after cullings in the 1970s and 1980s. Because of the timing, these attacks have been interpreted as vindictive. In parts of India, male elephants regularly enter villages at night, destroying homes and killing people. Elephants killed around 300 people between 2000 and 2004 in Jharkhand while in Assam, 239 people were reportedly killed between 2001 and 2006.Local people have reported their belief that some elephants were drunk during their attacks, although officials have disputed this explanation. Purportedly drunk elephants attacked an Indian village a second time in December 2002, killing six people, which led to the killing of about 200.

Elephant. no similar animals familiar to Western audiences. The use of the elephant as a symbol of the U.S. Republican Party began with an 1874 cartoon by Thomas Nast. As characters, elephants are most common in children's stories, in which they are generally cast as models of exemplary behaviour. They are typically surrogates for humans with ideal human values. Many stories tell of isolated young elephants returning to a close-knit community, such as "The Elephant's Child" from Rudyard Kipling's "Just So Stories", Disney's "Dumbo," and Kathryn and Byron Jackson's "The Saggy Baggy Elephant". Other elephant heroes given human qualities include Jean.

Power inverter. A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as.

Power inverter. a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.## Input and output.## Input voltage.A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the.

Power inverter. are two basic designs for producing household plug-in voltage from a lower-voltage DC source, the first of which uses a switching boost converter to produce a higher-voltage DC and then converts to AC. The second method converts DC to AC at battery level and uses a line-frequency transformer to create the output voltage.## Square wave.This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce "humming" when connected to audio equipment and is generally unsuitable for sensitive electronics.## Sine wave.A power inverter.

Power inverter. device that produces a multiple step sinusoidal AC waveform is referred to as a "sine wave inverter". To more clearly distinguish the inverters with outputs of much less distortion than the "modified sine wave" (three-step) inverter designs, the manufacturers often use the phrase "pure sine wave inverter". Almost all consumer grade inverters that are sold as a "pure sine wave inverter" do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two-step) and modified sine wave (three-step) inverters. However, this is not critical for most electronics as they deal with the.

Power inverter. output quite well.Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switch-mode power supply (SMPS) devices, such as personal computers or DVD.

Power inverter. players, function on modified sine wave power. AC motors directly operated on non-sinusoidal power may produce extra heat, may have different speed-torque characteristics, or may produce more audible noise than when running on sinusoidal power.## Modified sine wave.The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a waveform which has voltage steps of zero, peak positive, zero, peak negative and again zero. This voltage value sequence is repeated continuously. The resultant voltage waveform better approximates the shape of a sinusoidal voltage.

Power inverter. entirely without problems, but if the item has a mains transformer, this can overheat depending on how marginally it is rated.However, the load may operate less efficiently owing to the harmonics associated with a modified sine wave and produce a humming noise during operation. This also affects the efficiency of the system as a whole, since the manufacturer's nominal conversion efficiency does not account for harmonics. Therefore, pure sine wave inverters may provide significantly higher efficiency than modified sine wave inverters.Most AC motors will run on MSW inverters with an efficiency reduction of about 20% owing to the harmonic content.

Power inverter. DC supply, in the manner of the MSN designs, but the switching takes place at a far faster rate, typically many KHz, so that the varying width of the pulses can be smoothed to create the sine wave. If a microprocessor is used to generate the switching timing, the harmonic content and efficiency can be closely controlled.## Output frequency.The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. The exception is in designs for motor driving, where a variable frequency results in a variable speed control.Also, if the.

Power inverter. output of the device or circuit is to be further conditioned (for example stepped up) then the frequency may be much higher for good transformer efficiency.## Output voltage.The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.Some inverters also allow selectable or continuously variable output voltages.## Output power.A power inverter will often have an overall.

Power inverter. battery from the others.## Applications.## DC power source usage.An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.## Uninterruptible power supplies.An uninterruptible power supply (UPS) uses batteries and an inverter to supply AC power when mains power is not available. When mains power is restored, a rectifier supplies DC power to recharge the batteries.## Electric motor speed control.Inverter circuits designed to produce a variable output.

Power inverter. voltage range are often used within motor speed controllers.The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load. Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools.Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table 1. The generated.

Power inverter. gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.## In refrigeration compressors.An inverter can be used to control the speed of the compressor motor to drive variable refrigerant flow in a refrigeration or air conditioning system to regulate system performance. Such installations are known as inverter compressors. Traditional methods of refrigeration regulation use single-speed compressors switched on and off periodically; inverter-equipped systems have a variable-frequency drive that control the speed of the motor and thus the compressor and cooling output. The variable-frequency AC from the inverter drives a brushless or.

Power inverter. induction motor, the speed of which is proportional to the frequency of the AC it is fed, so the compressor can be run at variable speeds—eliminating compressor stop-start cycles increases efficiency. A microcontroller typically monitors the temperature in the space to be cooled, and adjusts the speed of the compressor to maintain the desired temperature. The additional electronics and system hardware add cost to the equipment, but can result in substantial savings in operating costs. The first inverter air conditioners were released by Toshiba in 1981, in Japan.## Power grid.Grid-tied inverters are designed to feed into the electric power distribution.

Power inverter. hundred megawatts, are used to deliver power from high voltage direct current transmission systems to alternating current distribution systems.## Solar.A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.Solar micro-inverters differ from conventional inverters, as an individual micro-inverter is attached to each solar panel. This can improve the overall efficiency of the system. The output from several micro-inverters is then combined and often fed to the electrical.

Power inverter. grid.In other applications, a conventional inverter can be combined with a battery bank maintained by a solar charge controller. This combination of components is often referred to as a solar generator.Solar inverters are also used in spacecraft photovoltaic system.## Induction heating.Inverters convert low frequency main AC power to higher frequency for use in induction heating. To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC sources employed, the structure becomes more reliable and the output voltage has.

Power inverter. higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved. This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors.There are three kinds of level shifted modulation techniques, namely: Phase Opposition Disposition (POD) Alternative Phase Opposition Disposition (APOD) Phase Disposition (PD)## HVDC power transmission.With HVDC power transmission, AC power is rectified and high voltage DC power is transmitted to another location. At the receiving location, an inverter in a static inverter.

Power inverter. plant converts the power back to AC. The inverter must be synchronized with grid frequency and phase and minimize harmonic generation.## Electroshock weapons.Electroshock weapons and tasers have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9 V DC is converted to 400–2000 V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached. When the threshold (set by way of an airgap or TRIAC) is reached, the capacitor dumps its.

Power inverter. entire load into a pulse transformer which then steps it up to its final output voltage of 20–60 kV. A variant of the principle is also used in electronic flash and bug zappers, though they rely on a capacitor-based voltage multiplier to achieve their high voltage.## Miscellaneous.Typical applications for power inverters include: Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools. Use in power generation systems such as electric utility companies or solar.

Power inverter. generating systems to convert DC power to AC power. Use within any larger electronic system where an engineering need exists for deriving an AC source from a DC source. Frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.## Circuit description.## Basic design.In one simple inverter circuit,.

Power inverter. DC power is connected to a transformer through the center tap of the primary winding. A relay switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and.

Power inverter. provide large power handling capability in a semiconductor device, and can readily be controlled over a variable firing range.The switch in the simple inverter described above, when not coupled to an output transformer, produces a square voltage waveform due to its simple off and on nature as opposed to the sinusoidal waveform that is the usual waveform of an AC power supply. Using Fourier analysis, periodic waveforms are represented as the sum of an infinite series of sine waves. The sine wave that has the same frequency as the original waveform is called the fundamental component. The other sine waves,.

Power inverter. car that is moving can turn into a source of energy and can, with the right inverter topology (full H-bridge) charge the car battery when decelerating or braking. In a similar manner, the right topology (full H-bridge) can invert the roles of "source" and "load", that is, if for example the voltage is higher on the AC "load" side (by adding a solar inverter, similar to a gen-set, but solid state), energy can flow back into the DC "source" or battery.Based on the basic H-bridge topology, there are two different fundamental control strategies called basic frequency-variable bridge converter and PWM.

Power inverter. control. Here, in the left image of H-bridge circuit, the top left switch is named as "S1", and others are named as "S2, S3, S4" in counterclockwise order.For the basic frequency-variable bridge converter, the switches can be operated at the same frequency as the AC in the electric grid. However, it is the rate at which the switches open and close that determines the AC frequency. When S1 and S4 are on and the other two are off, the load is provided with positive voltage and vice versa. We could control the on-off states of the switches to adjust the.

Power inverter. AC magnitude and phase. We could also control the switches to eliminate certain harmonics. This includes controlling the switches to create notches, or 0-state regions, in the output waveform or adding the outputs of two or more converters in parallel that are phase shifted in respect to one another.Another method that can be used is PWM. Unlike the basic frequency-variable bridge converter, in the PWM controlling strategy, only two switches S3, S4 can operate at the frequency of the AC side or at any low frequency. The other two would switch much faster (typically 100 KHz) to create square voltages.

Power inverter. level of distortion caused by harmonics. The waveform quality of AC produced directly by H-bridge mentioned above would be not as good as we want.The issue of waveform quality can be addressed in many ways. Capacitors and inductors can be used to filter the waveform. If the design includes a transformer, filtering can be applied to the primary or the secondary side of the transformer or to both sides. Low-pass filters are applied to allow the fundamental component of the waveform to pass to the output while limiting the passage of the harmonic components. If the inverter is designed to.

Power inverter. provide power at a fixed frequency, a resonant filter can be used. For an adjustable frequency inverter, the filter must be tuned to a frequency that is above the maximum fundamental frequency.Since most loads contain inductance, feedback rectifiers or antiparallel diodes are often connected across each semiconductor switch to provide a path for the peak inductive load current when the switch is turned off. The antiparallel diodes are somewhat similar to the "freewheeling diodes" used in AC/DC converter circuits.Fourier analysis reveals that a waveform, like a square wave, that is anti-symmetrical about the 180 degree point contains only odd harmonics,.

Power inverter. simplifies the electronics, but the inductors and capacitors tend to be large and heavy. Its high efficiency makes this approach popular in large uninterruptible power supplies in data centers that run the inverter continuously in an "online" mode to avoid any switchover transient when power is lost.A closely related approach uses a ferroresonant transformer, also known as a constant voltage transformer, to remove harmonics and to store enough energy to sustain the load for a few AC cycles. This property makes them useful in standby power supplies to eliminate the switchover transient that otherwise occurs during a power failure while.

Power inverter. size and volume. In 2014, Google together with IEEE started an open competition named Little Box Challenge, with a prize money of $1,000,000, to build a (much) smaller power inverter.## History.## Early inverters.From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas-filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.The origins of electromechanical inverters explain the source of the term "inverter". Early AC-to-DC converters.

Power inverter. used an induction or synchronous AC motor direct-connected to a generator (dynamo) so that the generator's commutator reversed its connections at exactly the right moments to produce DC. A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame. The result with either is AC-in, DC-out. With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to.

Power inverter. be "mechanically rectified AC". Given the right auxiliary and control equipment, an M-G set or rotary converter can be "run backwards", converting DC to AC. Hence an inverter is an inverted converter.## Controlled rectifier inverters.Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier (SCR) that initiated the transition to solid state inverter circuits.The "commutation" requirements of SCRs are a key consideration in SCR circuit designs. SCRs do not turn off or "commutate" automatically when the gate control signal is shut off. They.

Power inverter. only turn off when the forward current is reduced to below the minimum holding current, which varies with each kind of SCR, through some external process. For SCRs connected to an AC power source, commutation occurs naturally every time the polarity of the source voltage reverses. SCRs connected to a DC power source usually require a means of forced commutation that forces the current to zero when commutation is required. The least complicated SCR circuits employ natural commutation rather than forced commutation. With the addition of forced commutation circuits, SCRs have been used in the types of inverter circuits described.

Power inverter. above.In applications where inverters transfer power from a DC power source to an AC power source, it is possible to use AC-to-DC controlled rectifier circuits operating in the inversion mode. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. This type of operation can be used in HVDC power transmission systems and in regenerative braking operation of motor control systems.Another type of SCR inverter circuit is the current source input (CSI) inverter. A CSI inverter is the dual of a six-step voltage source inverter. With a current source inverter, the DC power supply is configured.

Power inverter. as a current source rather than a voltage source. The inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform. CSI inverter commutation methods include load commutation and parallel capacitor commutation. With both methods, the input current regulation assists the commutation. With load commutation, the load is a synchronous motor operated at a leading power factor.As they have become available in higher voltage and current ratings, semiconductors such as transistors or IGBTs that can be turned off by means of control signals have become the preferred switching components.

Power inverter. for use in inverter circuits.## Rectifier and inverter pulse numbers.Rectifier circuits are often classified by the number of current pulses that flow to the DC side of the rectifier per cycle of AC input voltage. A single-phase half-wave rectifier is a one-pulse circuit and a single-phase full-wave rectifier is a two-pulse circuit. A three-phase half-wave rectifier is a three-pulse circuit and a three-phase full-wave rectifier is a six-pulse circuit.With three-phase rectifiers, two or more rectifiers are sometimes connected in series or parallel to obtain higher voltage or current ratings. The rectifier inputs are supplied from special transformers that provide phase.

Power inverter. shifted outputs. This has the effect of phase multiplication. Six phases are obtained from two transformers, twelve phases from three transformers and so on. The associated rectifier circuits are 12-pulse rectifiers, 18-pulse rectifiers and so on...When controlled rectifier circuits are operated in the inversion mode, they would be classified by pulse number also. Rectifier circuits that have a higher pulse number have reduced harmonic content in the AC input current and reduced ripple in the DC output voltage. In the inversion mode, circuits that have a higher pulse number have lower harmonic content in the AC output voltage waveform.## Other.

Jigsaw puzzle. A jigsaw puzzle is a tiling puzzle that requires the assembly of often irregularly shaped interlocking and mosaiced pieces, each of which typically has a portion of a picture. When assembled, the puzzle pieces produce a complete picture.In the 18th century, jigsaw puzzles were created by painting a picture on a flat, rectangular piece of wood, then cutting it into small pieces. Despite the name, a jigsaw was never used. John Spilsbury, a London cartographer and engraver, is credited with commercialising jigsaw puzzles around 1760. They have since come to be made primarily of cardboard.Typical images on jigsaw puzzles include.
