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

2010 July 19

The most typical question asked when looking for a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two top projector imaging technologies. With so many business brands and different models available, it can be difficult for consumers to decide between these technologies. The fact is that LCD projectors provide better image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with reproducing the same rate of image quality.

Think of a set of blinds in your household for your bedroom window. By pulling on a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel works like a unique shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from when the projector turns on to when the picture reaches your screen is absolutely important to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by separating it into red, blue and green components, by three mirrors which direct the coloured light to 3 different LCD panels. The 3 LCD panels cast the elements of the image by shining each pixel on and off. The pixels are then meshed in a glass prism to create the projector image. A significant point to know about LCD projectors is that all three colours are projected onto your screen at the same time. The way a DLP projector operates is vastly different and even the way an image comes out is not the same. With DLP, white light from the lamp is processed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to projecting an image forms a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to form the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s vision will then pull together each coloured element of the image into the whole image. From LCD projectors, all colours are available all the time to create the highest brightness and great colour accuracy. In DLP, just one colour is available at once, and so causing lower colour brightness and accuracy. Some manufacturers have placed a white segment in the colour wheel to improve general brightness, but this also damages colour accuracy.

I see in forums all the time that DLP has a higher contrast ratio and thus must be superior quality. For those who are uncertain, 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 provide high contrast specifications compared to a majority of LCD projectors. Initially, this seems to be a plus, however, in real life, the true black level is determined by the ambient light in the room while the projector is used. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you are trying to bring to life includes moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector forms with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change position between the time red, blue and green colours are shone. LCD projectors do not have this characteristic because every colour is sent at once. DLP developers have formed 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them almost impossible for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Jump back to high school science, and remember how various colours of light refract differing amounts when shone through the same lens. The downside with DLP projectors is that they have the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in different ways. Usually with a DLP projector, an extra yellow colour will show above and an extra blue will show below something as simple as a single black line. During manufacturing LCD projectors can be adjusted to remove these effects on the projected image, as each colour is directed on separate LCD panels.

The sole veritable benefit (excluding price) with choosing a DLP projector is its smaller size and weight. However, this is only relevant for transporting the device and has to be traded off against the image advantages of LCD projectors. If resulting picture quality is vital to you, then the choice is no-brainer. Take an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

2010 July 16

As the Dutch rose to dominance in sea power during the 17th century, the first yacht was a leisure craft used first by royalty and then by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting rose as classy for the rich and royalty, but after that period the trend did not last.

The first yacht group in the British Isles, the Water Club, was started at about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and held great naval panoply and gravity. 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, after merging with other groups, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some ordered fashion on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started 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 location of British yacht racing. The society at Cowes became the Royal Yachting Club, again at the accession of George IV. Each member was required to have boats of at least 20 tons (20,321 kg). Sailing races for large stakes were held, and the club life was lovely. Eventually Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English gained dominance. Sailing was mostly for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a standard of luxury and sophistication for the later yachts in those waters from the late 19th century. The first continuing American yacht society, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens began the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The design of sizeable yachts was first heavily impacted by the victory of America, which was drawn by George Steers for a syndicate started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its victory at Cowes in 1851. Earlier yachts were not designed and built in the modern sense, with merely a model being used. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the employment of the research of aerodynamics do for the craft of sails and rigging what science had earlier done for hulls.

Because almost all sailboats had been individually custom-built, there was a desire for handicapping boats before the one-design class boats were built. Thus, 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 most rapidly flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are manufactured to single requirements in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing for those boats can be done on an even playing field with no handicapping necessary. A prime example is the uniform International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

For the time that yachting belonged largely for the aristocracy and the wealthy, expense was no problem, and the size of boats increased, in both length and weight. The rise and desire of smaller boats came in the second half of the 19th century from 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 made plain the value of smaller yachts. Later in the 20th century, particularly after World War II, smaller racing and recreational craft became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, during which steam started to take the place of sail power in public craft, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure boats. Sizeable power yachts were progressed to a high element, and long-distance travel was a favoured activity of the affluent. The earliest power yachts were paddle-wheel boats; they then gave rise to boats powered by the fully submerged screw or propeller type of propulsion. As well as naval and merchant craft, auxiliaries with both sail and power were the yacht fashion for many years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the manufacture of large steam yachts. Conspicuous within these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service in World War II.

As larger and better quality internal-combustion engines were developed, many big boats started using them for power. The development of the diesel engine, with heavy oil for fuel, was furthered in World War I. From the decade after that, large power-yacht building flourished, hitting a climax in the Orion (1930) at 3,097 tons. From that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power craft fell away after 1932, and the fashion after that was in preference of smaller, less costly yachts. From World War II, many small naval craft were traded by private owners for conversion to yachts. By the late 20th century, yachting is a globally beloved competition enjoyed by thousands of yachtsmen individually manning and upkeeping their own small leisure craft. The number of craft and owners increased steadily, not only in the traditional areas along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

2010 July 8

Taxes can be distinguished by the effect they have on the allocation of income and wealth. A proportional tax is a kind that places the same relative onus on all taxpayers—i.e., when tax liability and income move in equal levels. A progressive tax is characterized by a larger than proportional growth in the tax liability in relation to the growth in income, and a regressive tax is recognisable by a less than proportional growth in the comparable onus. Therefore, progressive taxes are regarded as fighting the lack of equality in income distribution, while regressive taxes can increase these inequalities.

The taxes that are normally believed to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so for the upper-income group—particularly if a taxpayer is able to reduce his tax base by declaring deductions or by excluding some particular income parts from his taxable income. Proportional tax rates if applied to lower-income classes would also be more progressive if such exemptions of a personal nature are made.

Income measured over the course of a given year may not absolutely provide the best measure of taxpaying status. For example, transitory growth in income might be saved, and within temporary declines in income a taxpayer may elect to provide for consumption by decreasing savings. Therefore, if taxation is compared with “permanent income,” it can be less regressive (or more progressive) than when compared with annual income.

Sales taxes and excises (with the exception of those on luxuries) are generally regressive, because the share of one’s income consumed or spent for specific goods decreases as the level of personal income grows. 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, principally due to uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden is dependant crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic effects of taxation, it is essential to differentiate between varied ideas of tax rates. The statutory rates include those nominated in the legislation; generally speaking these are marginal rates, but in some cases they are median rates. Marginal income tax rates signify the fraction of incremental income taken by taxation when income rises by one dollar. Hence, if tax liability grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that rise as income increases. Heavy analysis of marginal tax rates are required to consider provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than specified by the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the relevant ones for regarding incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate applicable to income from business and capital, since it may depend on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates indicate the part of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates commonly grow with income, both because personal allowances are permitted for the taxpayer and dependents and because marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households could dwarf these effects, producing regressivity, as signified by average tax rates that fall as income increases.

The Development of Data Projectors

2010 June 30
by squadron

The LCDs put for projection systems are usually small reflective or transmissive panels lit up by a forceful arc lamp source. A number of lenses magnifies the reflected or transmitted image and then displays it on the screen. In front-projection systems the LCD is located on the same side of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of higher cost and performance can use three discrete LCD panels, creating separate red, green, and blue images that combine to create a coloured picture on the screen.

The growing desire for video displays has granted a growth in emphasis on the switching speed of liquid crystals. This has led to the invention of objects build with smectic liquid crystals, certain types of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most complex smectic device. In it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are on a tilt, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a subtle turn up of the optical activity and the tilt of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. So, there must be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The respective change in optical properties can make a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been commercialized for larger passive-matrix presentations, but their high cost and complexity has hindered them from enjoying any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as parts in projection systems or as viewfinders in digital cameras. Their speedy reaction allows them to be used in time-sequential colour systems, in which highly expensive colour filters are emulated by a coloured backlight that flashes red, green, and blue in quick pulsing (about 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state for the red and green periods and to a nontransmissive state during the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

2010 June 26
by squadron

Out of each of the furniture items, the chair could be the paramount one. While many other items (except the bed) are intended to support objects, the chair supports a human form. The term chair must be looked upon here in the larger sense, from stool to throne to developed makes like a bench and sofa, which may 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 stimulating as its history as an art and craft. The chair is not simply a physical support or an aesthetic object; it was also an indicator of social placement. From the historical royal courts there were plain distinctions between sitting on a chair with arms, sitting on a chair with a back but no arms, and having to sit on a stool. Since the past century, the director’s and manager’s chair has risen an indicator of superior position, and even in democratic government debate the speaker sits on a higher platform.

As its furniture form, the chair can be used for a range of different models. There are chairs manufactured to suit man’s age and physical condition (the high chair, the wheelchair) and to show his rank in society (the executive chair, the throne). From the olden days there were chairs for births (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). There are chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded up, chairs on wheels, and chairs on runners.

Modern day living has designated new chairs in automobiles and aircraft. All these chair forms has adapted to conform to evolving human uses. From its unique connection with man, the chair lives to its full advantage only when being used. Though it is irrelevant to one’s appreciation of a cupboard or a dresser drawers if there are things inside or not, a chair is really understood and tested with a person utilising it, because chair and sitter need each other. Thus the different areas of a chair were labeled likened to the parts of our human form: arms, legs, feet, back, and seat.

Because the first role of a chair is to support our human body, its credit is tested firstly on how fully it measures up to this practical function. Within the manufacture of the chair, the builder is restricted within the static rules and principal measurements. Inside these limits, however, the chair maker has marvellous freedom.

The history of the chair extends over a period of several thousand years. There are peoples that made individual chair types, seen of the topmost task in the industries of technique and aesthetics. Out of those peoples, a mention needs to 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of careful make, are now known from discoveries made in tombs. The first of these two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have four legs formed not unlike those of some animal, a curved seat, and a sloping back supported above vertical stretchers. In this design a stable triangular construction was obtained. There was from our view no noteworthy differentiation from the construction of Egyptian thrones and chairs for ordinary populace. The real change was in the kind of ornamentation, in the evidence of expensive inlays. The Egyptian folding stool most probably was crafted for an easily packed seat for army. As a camp stool that form stayed around til much later days. But the stool also then was designed as the task of a ceremonial seat, its technical role as a folding stool simply forgotten. This can from today be found, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but can not be folded because the seats are worked from wood. The simple manufacture of the folding stool, consisting of two frames that cycle on metal bolts and have a seat of leather or fabric set between them, then appeared somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this type is the folding stool, of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not with any ancient item still extant but as seen in a wealth of pictorial material. The best recognised is the klismos depicted on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of which are visible. These curved legs were thought to be executed of bent wood and were likely to have been needed to bear great pressure with the weight of the sitter. The joints joining the legs to the frame of the seat are therefore super durable and were visibly denoted.

The Romans borrowed from the Greek designs; quite a few statues of seated Romans are chairs of a thicker and in appearance somewhat less delicately built klismos. Both features, the light and the heavy, were popularised during the Classicist period. The klismos style can be seen in French Empire chairs, in English Regency, and in particular forms of considerable originality around Denmark and Sweden from 1800.

China
The progression of the chair in China is not able to be tracked as far back as the progression of the chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed series of drawings and artworks has been kept safe, showing the inside and outside of Chinese houses and the furniture. Also preserved since the 16th century are a collection of chairs made from wood or lacquered wood, that show an intriguing similarity to pictures of previous chairs.

Just as in Egypt, there existed two fundamental chair forms in China: a chair having four legs and a folding stool. That four-legged chair has been designed both with or without arms although always with its square seat and straight stiles (standing side supports) to give support to the back. In one image, it has been seen, the stiles are delicately curved by the arms for the purpose of sit right with the angle of the S-shaped back splat (the centre upright of its chairback). Together, all three limbs had been mortised into the yoke-like top rail. Although the idea of this back splat had an influence on English chairs in the Queen Anne period, wooden pieces that only to a particular capability reinforce corner joints (and were loose to top it off) represent an element solely to Chinese chairs. The four legs pass through the seat frame, which ends over the rounded staves. Members are round in section or have rounded edges—referable perhaps to the bamboo tradition. The seat is not pleasant and might have had a plaited seat. These chairs required the sitter to hold themselves stiff and upright; for if too much weight is pushed on the back, the chair has a tendency to fall over. In patriarchal Chinese homes of this era armchairs likely were kept for senior people, for they were greatly respected.

The Chinese folding stool is believed to have come to China from the West. It does not differ so very much from the Egyptian and Scandinavian folding stools, but it possesses a difference in that the top rail is elegantly held to the two legs of the stool with a curved member, which is often possessing metal mounts. From a Western understanding the resultant effect of these furniture styles is stylized. The constructive and decorative issues are combined in a way that is all at once both naïve and refined. The patched up appearance is a result of the way that the individual items do not look to have been affixed with either glue or screws, but have been mortised with one another and locked into position in the style of a Chinese puzzle.

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

The Netherlands: 17th century
A low, square, upholstered kind of chair is found in engravings of the interiors of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not decided that the style actually originated in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was made in considerable numbers, as can be surmised from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up by a wall. The design asserts itself by its elegant proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is to say, as developed in Paris around 1750—conquered most of Europe and was imitated or copied in the mid-20th century. The design owes the popularity to a combination of relaxation and charm. The seat suits to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof use wood of rather thick dimensions; but each member is deeply molded, all extraneous wood has been taken away, and more upmarket items can be further embellished with highly delicate and decorative woodwork. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all of the upholstery on the seat, back, and armrests; crosshatched cane is in some cases used in place of upholstery.

English chairs from the 18th century were more variable in style than the French. The French touch for stylistic uniformity, which came from the most distinguished circles in Paris and Versailles throughout 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 well-known and was widely distributed throughout the world.

Late 18th to 20th century
During 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 products 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?

2010 June 23
by squadron

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping creates the information from which accounts are written but is a different process, prior to accounting.

Fundamentally, bookkeeping provides two types of information: (1) the current value, or equity, of an entity and (2) changes in value—profit or loss—taking placement in the entity during a given time.

Management officials, investors, and credit grantors all need to have such information: management so as to assess the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the outcome of business operations and make decisions about buying, holding, and selling securities; and credit grantors so as to assess the financial statements of an entity in deciding whether to give a loan.

Bits and pieces of financial and numerical charts are found for nearly every state with a commercial background. Records of trading contracts were discovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The double-entry way of bookkeeping began with the development of the business republics of Italy, and tutorial manuals for bookkeeping were developed in the 15th century in several Italian cities.

Within the late 18th and early 19th centuries, the Industrial Revolution granted an important stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made factual financial records a necessity. The history of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in part, helped shaping it. The international spread of industrial and commercial activity needed higher professional decision-making methodology, which then required higher sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government legislation became more important and resulted in greater need for information; business firms had to show available information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the demand for bookkeeping for their inner departmental operations became higher.

Though bookkeeping methods can be extremely detailed, it is all based on two styles of books utilised in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, and so on), and the ledger must have the records of individual accounts. The daily records in the journals are written in the ledgers.

At the end of each month, by general practice, an income statement and a balance sheet are made from the trial balance posted within the ledger. The purpose of the income statement or profit-and-loss statement is to give an analysis of those changes that took place in the ownership equity as a result of the operations of the period. The balance sheet displays the financial condition of the business at a particular day with regard to assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

2010 June 9

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 produced 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 wish 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.
