Projectors: LCD Verses DLP (The downfall of DLP technology)

Posted by Maxie in Uncategorized on 19-07-2010

Tags: ,

The common question that is asked when acquiring a new projector for the home, office, or classroom is: should I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different models available, it can be confusing for the buyer to choose between these technologies. The fact is that LCD projectors give better image quality and colour accuracy. The next part of this article tells you why DLP projectors struggle with bringing up a similar grade of image quality.

Imagine a set of blinds in your home over your bedroom window. With the twist of a rod you can make the shutters open or closed, according to whether you want to let light in or not. And that is exactly how an LCD projector functions. Each pixel operates like a single shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from when the projector is turned on to when the picture reaches your screen is ultimately significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by dividing it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by turning each pixel on and off. The pixels are then simultaneously processed in a glass prism to create the projector image. A significant point to realise about LCD projectors is that all three colours are projected onto your projected surface at once. The way a DLP projector operates is vastly different and even the way an image appears is not the same. With DLP, white light from the lamp is processed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image forms a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to form the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eye will then put together each coloured element of the image into the total image. Using LCD projectors, all colours are available all the time to deliver the best brightness and great colour accuracy. In DLP, just one colour is available at once, causing lower colour brightness and accuracy. Some designers have included a white segment into the colour wheel to improve brightness generally, but this further degrades colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and as such must be better quality. For those unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is able to produce. DLP projectors do have high contrast specifications in comparison to most LCD projectors. At first glance, this must be an advantage, however, in reality, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you wish to see has moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most common artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change between the time red, blue and green colours are displayed. LCD projectors do not have this characteristic because the colours are processed at once. DLP manufacturers have developed 3DLP solutions using 3 chips to fix the colour break up problem, but the price tag of these projectors make them hardly practical for most businesses and consumers.

Another difference between LCD and DLP is how they compensate for the refractive qualities of light. Think back to high school science, and remember how different colours of light refract different amounts when shone through the same lens. The downside with DLP projectors is that they use the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light in a different way. Usually with a DLP projector, some extra yellow colour will come through above and a spill of blue will appear below something as simple as a single black line. During manufacturing LCD projectors can be adjusted to reduce these effects on the projected image, as each colour is projected on its own LCD panels.

The isolated true benefit (excluding price) with picking a DLP projector is its smaller overall size and weight. However, this is only relevant to transport and must be traded off against the image benefits of LCD projectors. If the result of the picture quality is vital to you, then the decision is simple. Take an LCD projector! LCD projectors will always produce bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

Posted by Maxie in Uncategorized on 16-07-2010

Tags: ,

As the Dutch came to preeminence in sea power during the 17th century, the first yacht had been a pleasure craft used mostly by royalty and then by the burghers for the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English monarchy in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting became classy for the wealthy and nobility, but after that point the trend did not last.

The first yacht club in the British Isles, the Water Club, was instigated at about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, with much naval panoply and formality. The closest thing to racing was the “chase,” for which the “fleet” pursued a fictional enemy. The club persisted, mostly as a social club, until 1765, and in 1828, by joining with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized method on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it came to be called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been initiated at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent - the strait between the mainland and the Isle of Wight - the perpetual site of British yachting. The organisation at Cowes became the Royal Yachting Club, also at the ascension of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing races for large stakes were held, and the social life was superlative. Eventually Royal Yachting Club boats increased in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and persisted when the English held dominance. Sailing was for the most part for fun and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a benchmark of luxury and sophistication for the later yachts in those waters from the late 19th century. The first persisting American yacht group, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The style of sizeable yachts was first heavily impacted by the victory of America, which was designed by George Steers for a club led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its success at Cowes in 1851. Early yachts were not designed and crafted in the modern sense, with only a model used. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the use of the science of aerodynamics do for the structure of sails and rigging what such science had done earlier for hulls.

Because almost all sailboats had to be individually manufactured, there arose a need for handicapping boats before the one-design class boats were built. Hence, a rating rule came into being, which resulted in the International Rule, accepted in 1906 and edited in 1919. In modern times, one of the rapidly flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to the same specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between these boats can be held on an even playing field with no handicapping required. A great example is the uniform International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

As long as yachting belonged mostly for the nobility and the affluent, cost was no issue, and the size of boats increased, in both length and weight. The promotion and preference of smaller craft occurred in the second half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the seaworthiness of less sizeable boats. Thereafter in the 20th century, particularly after World War II, smaller racing and pleasure yachts became commonplace, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, during which steam began to take the place of sail power in public craft, the steam engine, and later the internal-combustion engine, were increasingly used in leisure boats. Large power yachts were furthered to a high degree, and long-distance sailing became a preferred occupation of the well off. The earliest power yachts were paddle-wheel boats; they then made way to yachts powered by the wholly submerged screw or propeller sort of propulsion. Like naval and merchant yachts, auxiliaries carrying both sail and power were the yacht archetype for many years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were only power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the manufacture of large steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of over 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service during World War II.

As larger and more reliable internal-combustion engines were produced, many big yachts were using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced from World War I. During the decade after that, big power-yacht manufacture blossomed, climaxing in the Orion (1930) at 3,097 tons. From that period the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power yachts declined from 1932, and the trend thereafter was for smaller, less pricey yachts. From World War II, a lot of small naval vessels were sold to private owners for conversion to yachts. By the late 20th century, yachting had become a widespread beloved sport enjoyed by thousands of yachtsmen personally owning and upkeeping their own small leisure yachts. The popularity of yachts and owners is increasing steadily, not only in the traditional places by the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Posted by Maxie in Uncategorized on 08-07-2010

Tags: ,

Taxes can be distinguished by the impact they have on the allocation of income and wealth. A proportional tax is a kind that imposes the same relative liability on each taxpayer—i.e., where tax liability and income increase in the same proportion. A progressive tax is recognisable by a larger than proportional growth in the tax liability relative to the increase in income, and a regressive tax is characterizable by a less than proportional rise in the related onus. Thus, progressive taxes are seen as removing a lack of equality in income distribution, while regressive taxes are found to have the effect of increasing these inequalities.

The taxes that are generally believed to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so in the upper-income categories—in particular if a taxpayer is able to lessen his tax base by declaring deductions or by taking some certain income aspects from his taxable income. Proportional tax rates which are applied to lower-income classes could also be more progressive if such exemptions of a personal nature are declared.

Income measured over the course of a given year may not definitely come up with the most suitable measure of taxpaying ability. For example, transitory growth in income may be saved, and within temporary declines in income a taxpayer might decide to provide for consumption by taking from savings. So, if taxation is held in comparison with “permanent income,” it can be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are mostly regressive, because the dissemination of one’s income consumed or spent for specific goods lowers as the amount of personal income is raised. Poll taxes (also called head taxes), nominated as a set amount per capita, clearly are regressive.

It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to a lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden rests for the most part on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic purpose of taxation, it is essential to differentiate between varied concepts of tax rates. The statutory rates are those nominated in the legislation; often these are marginal rates, but sometimes they are average rates. Marginal income tax rates indicate the fraction of incremental income that is taken by taxation when income grows by one dollar. Therefore, if tax onus rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that grow as income increases. Careful analysis of marginal tax rates are required to consider provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than indicated within the statutory rates. Since marginal rates display how after-tax income moves in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applied to income from business and capital, as it may rely on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates show the portion of total income that is demanded in taxation. The pattern of average rates is the one that is important for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally grow with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received mostly by high-income households may swamp these effects, forcing regressivity, as signified by average tax rates that lower as income grows.

The Development of Data Projectors

Posted by Maxie in Uncategorized on 30-06-2010

The LCDs put in projection systems are typically small reflective or transmissive panels set off by a powerful arc lamp source. A series of lenses magnifies the reflected or transmitted image then displays it on a screen. For front-projection systems the LCD is placed on the side of the screen as the viewer, while in rear-projection systems the screen is illuminated from behind. Projectors of greater expense and capacity might use three distinct LCD panels, casting separate red, green, and blue images that mesh to create a coloured image on the screen.

The increase in demand for pictographic displays has placed a growth in emphasis on the switching speed of liquid crystals. This has required the invention of items build with smectic liquid crystals, particular types of which possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most developed smectic device. In it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are on a slant, as demonstrated in the figure. The host liquid crystal contains optically active molecules, and a slight consequence of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. So, there is a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The resultant change in optical properties can make a change from light to dark if or when one or more polarizers are utilised.

SSFLC devices have been publicized for larger passive-matrix displays, but their cost and detail has hindered them from enjoying any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as parts in projection systems or as viewfinders in digital cameras. Their fast reaction allows them to be employed in time-sequential colour systems, in which expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast pulsing (around 100 cycles in a second). For example, the liquid crystal might be switched to a transmissive state during the red and green periods but then to a nontransmissive state in the blue period, having the upshot that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Posted by Maxie in Uncategorized on 26-06-2010

Tags: ,

Of all furniture forms, the chair may be the paramount one. While most other objects (except the bed) are created to support objects, the chair supports the human form. The term chair is intended to be looked upon here in the most open sense, from stool to throne to derivative makes including the bench and sofa, which might be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently labeled.

The social history of the chair is as curious as its history as a creative craft. The chair is not merely a physical support and/or aesthetic artwork; it historically was symbolic of social place. Within the historical royal courts there were plain signifiers between possessing a chair with arms, or a chair with a back but without arms, or worse having to sit on a stool. From the 20th century, a director’s and manager’s chair has become an identifier of superior status, and in democratic governments the speaker sits on a raised platform.

As a furniture creation, the chair can be employed for a wealth of various models. There are chairs designed to attend to man’s age and physical capabilities (the high chair, the wheelchair) and to show his position in society (the executive chair, the throne). During past times there were chairs for births (birth chairs); during the 20th century, there have been chairs for ending life (the electric chair). There are chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed particular chairs in automobiles and aircraft. Every one of these chair shapes has changed to suit to growing human desires. Due to its particular connection with man, the chair comes to its full advantage only when being utilised. Though it does not make any difference to one’s appreciation of a cupboard or a chest of drawers whether there are things inside or not, a chair is seen best and evaluated by a person using it, for chair and sitter suit each other. Thus the different parts of a chair have been given labels according to the areas of the human form: arms, legs, feet, back, and seat.

Because the basic role of a chair is to support your body, its worth is valued generally from how fully it measures up to this practical use. In the manufacture of the chair, the chair maker is bound within particular static regulations and principal measurements. Within these boundaries, however, the chair designer has awesome freedom.

The history of the chair covers a period of several thousand years. There are civilizations that held iconic chair forms, as expressions of the premier craft in the spheres of craft and design. Within these peoples, individual note must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of masterful design, are known from tomb findings. The first one of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair had four legs designed similar to those of a chosen animal, a curved seat, and a sloping back supported over vertical stretchers. In this way a solid triangular design was made. There was in our view no notable difference in the construction of Egyptian thrones and chairs for regular populace. The general change was in the decorative ornamentation, in the choice of more valuable inlays. The Egyptian folding stool most probably was manufactured as an easily packed seat for army soldiers. As a camp stool that type existed until much later points in time. But the stool then also was designed as the use of a ceremonial seat, its original job as a folding stool fast forgotten. This can now be noted, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are made in the construction of folding stools but cannot be folded as the seats are made from wood. The simplistic construction of the folding stool, made of two frames that turn on metal bolts and have a seat of leather or fabric set between them, can be seen but somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this kind is the folding stool, made of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is found not from any ancient fossil still existing but in a large amount of pictorial items. The significant kind is the klismos depicted on the Hegeso Stele at the Dipylon burial ground outside Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs are displayed. These creative legs were considered to have been crafted out of bent wood and were likely to have been subjected to huge pressure with the weight of the sitter. The joints holding the legs to the frame of the seat would have had to be therefore super solid and were particularly indicated.

The Romans borrowed from the Greek design; evidence of casts of seated Romans display chairs of a thicker and in appearance kind of less delicately designed klismos. Both kinds, light and heavy, were seen again as part of the Classicist period. The klismos design can be seen in French Empire furniture, in English Regency, and in some particular brands of marked iconicism within Denmark and Sweden circa 1800.

China
The ancestry of the chair in China cannot be followed as long as chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged folio of drawings and artworks has been kept safe, detailing the insides and outside of Chinese buildings and the designs of furniture. Another preservation of the 16th century are some chairs made from wood or lacquered wood, that bear an intriguing similarity to pictures of past chairs.

Same as in Egypt, there existed two standard chair designs in China: a chair of four legs and a folding stool. The four-legged chair can be found both with or without arms but always with the square seat and straight stiles (vertical side supports) to support the back. In one design, though, the stiles were delicately curved over the arms to conform correctly to the form of the S-shaped back splat (the main upright of the back). Each of the three sections are mortised on the yoke-like top rail. While the style of the Chinese back splat had an inspiration for English chairs in the Queen Anne period, wooden members that just to a restricted extent stabilise corner joints (and furthermore were loose in the bargain) signify a signature signatory to Chinese chairs. The four legs sit through the seat frame, which finishes about the rounded staves. All members are round in section or possesses rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is not comfortable and occasionally had a plaited bottom. These chairs demanded of the sitter to hold themselves stiff and upright; when too much weight is placed on the back, the chair has a tendency to topple over. In patriarchal Chinese houses of this period armchairs presumably were kept for the senior people, for they were esteemed greatly.

The Chinese folding stool is thought to have taken to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is intricately fixed to the two legs of the stool by means of a curved member, which is usually designed with metal mounts. From a Western point of view the overall effect of both furniture forms is stylized. The construction and decoration aspects are combined in a style that is simultaneously naïve and refined. The patchwork appearance is an upshot of the way that the individual items do not seem to have been put together by means of either glue or screws, but were mortised on one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its name on the chair. Artworks display a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between, stitched to show up a pattern of tiny pads. The front board and a corresponding board at the back could be folded after loosening some small iron hooks. Therefore the chair was a readily portable piece of furniture while traveling which, at the same era, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be evidenced in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this design of chair might also be found in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not determined that the design actually was instigated in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of thin dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was manufactured in impressive amounts, as evidenced from one of Abraham Bosse’s engravings, in which a whole row of this kind of chairs lined up against a wall. The design asserts itself by virtue of its elegant proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that is to say, as developed in Paris around 1750—spread over most of Europe and was imitated or copied during the mid-20th century. The style owes its popularity to a combination of comfort and charm. The seat adheres to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads on the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are solidly constructed on craftsmanlike methods in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of relatively thick measurements; but all members are deeply molded, all extraneous wood has been taken away, and more expensive designs can be further embellished with very delicate and decorative woodwork. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for the upholstery on the seat, back, and armrests; cane is sometimes used as an alternative to upholstery.

English chairs of the 18th century were more variable in form than the French. The French touch for stylistic uniformity, which lead from the premier circles in Paris and Versailles over most of France and was popular in several parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became popular and was widely distributed throughout the world.

Late 18th to 20th century
Within the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

In cheaper brands of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Posted by Maxie in Uncategorized on 23-06-2010

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping creates the information from which accounts are prepared but is a previous process, prerequisite to accounting.

Predominantly, bookkeeping provides two kinds of information: (1) the current value, or equity, of a business and (2) changes in value—profit or loss—taking place in the entity within a particular time.

Management officials, investors, and credit grantors all need such information: management in order to analyse the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors so as to judge the financial statements of a business in judging whether to grant a loan.

Traces of financial and numerical record charts have been found for just about every group of people with a commercial history. Records of commercial contracts have been found in the archaelogy of Babylon, and accounts for both farms and estates have been created in ancient Greece and Rome. The dual-entry process of bookkeeping came with the furthering of the business republics of Italy, and tutorial books for bookkeeping were developed in the 15th century in some Italian cities.

In the late 18th and early 19th centuries, the Industrial Revolution granted a significant stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a must-have. The past of bookkeeping, in fact, resembles closely the past of commerce, industry, and government and, in part, helped forming it. The international movement of industrial and commercial activity needed greater cosmopolitan decision-making processes, which itself demanded more sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government legislation became more important and resulted in greater demand for information; businesses had to show information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the requirement for bookkeeping for their own inner departmental operations increased.

Although bookkeeping procedures can be rather complex, it is all based on two types of books used in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger should have the records of individual accounts. The daily records in the journals are put in the ledgers.

At the end of every month, generally, an income statement and a balance sheet are prepared from the trial balance posted in the ledger. The job of the income statement or profit-and-loss statement is to give an analysis of the changes that have occurred in the enterprise equity as a result of the events of the period. The balance sheet provides the financial condition of the entity at any particular point taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

Posted by Maxie in Uncategorized on 09-06-2010

Tags: , ,

The invention of jet propulsion was ideal for fighter aircraft. Although at first it reduced range and endurance and often increased the take-off run. The German Messerschmitt Me 262 and the British Gloster Meteor twin jets saw action in 1944, together with the tailless Me 163 rocket interceptor which sacrificed range and endurance for astounding climb and speed in defending local areas against heavy bombers.

Germany was far in front of other countries in another factor too: armament. A range of 30 mm (1 inch) cannon, radically new high-speed cannon with multiple-revolver chambers, very large recoilless guns, spin-stabilised air-to-air rockets fired in salvoes, and wire-guided air-to-air missiles were all under test before the Luftwaffe s defeat. They gradually inspired similar developments in other countries: one German gun, the Mauser MG 213, led to the American Pontiac M-39, the French DEFA, the Russian NR-30, the Swiss Oerlikon KCA, and the British Aden, all of which are still in use.

Many early jet fighters were fitted into more or less conventional airframes. The fighter often considered the ultimate achievement of the piston era, the long-range North American P-51 Mustang appeared both in a twinned double-fuselage form and, with few changes, as a US Navy jet.

But the US Air Force decided to wait a year until its makers could sweep back the wings and tail at 35 degrees, which German research had shown could lead to higher speed. The result was the F-86 Sabre, which in 1948 set a speed record at 1,080 km/h (671 mph) and outflew all other fighters. Later versions carried radar and rockets and reached 1,150 km/h (715 mph).

During the Korean War (1950-3) the F-86 met a previously unknown machine built in the Soviet Union, the somewhat lighter and simpler MiG-15, and although the MiG could climb higher and had heavy cannon, the Sabre’s skilled pilots and better equipment gave it the edge in combat.

North American’s next fighter was the F-100 Super Sabre, which exceeded the speed of sound in level flight. The MiG bureau built the twin jet MiG-19, which was even faster, and is still in wide use. The US Air Force ordered various all-weather interceptors with largely automatic radar and flight control systems so that, with guided missiles, they could intercept and destroy enemy aircraft without the pilot ever seeing them.

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields yielded an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful trend to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever. Your jet fighter pilot experience is available in Melbourne, Cairns and Townsville. Visit flyingwarbirds.com.au for more details. For mini bus hire Brisbane, contact Group 1 Minibus.
