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

2010 July 19

The most common question heard when buying 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 most popular projector imaging technologies. With so many brands and different types available, it can be confusing for the buyer to pick between both technologies. Ultimately LCD projectors have superior image quality and colour accuracy. The article below will explain why DLP projectors struggle with bringing up 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, according to whether you want to let light in or not. This is exactly how an LCD projector operates. Each pixel operates like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as professionals like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the time the projector is turned on to when the picture reaches your screen is vitally important to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which project the coloured light to 3 different LCD panels. The 3 LCD panels make the elements of the image by turning each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. Something important to understad about LCD projectors is that all three colours are sent onto your projected surface at the same time. The way a DLP projector works is widely different and even the final product of how an image appears is not the same. With DLP, white light from the lamp is directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to making an image requires a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to construct 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 draw each coloured element of the image into the whole image. From LCD projectors, all colours are available all the time to form the top level of brightness and superb colour accuracy. In DLP, just one colour is available at a time, and so resulting in lower colour brightness and accuracy. Some developers have added a white segment in the colour wheel to improve brightness generally, but this then detracts from colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and ergo must be superior. 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 technology is able to produce. DLP projectors do provide high contrast specifications compared to many LCD projectors. Initially, this must be a plus, however, in truth, the true black level is determined by the ambient light in the room when the projector is being used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you plan to bring to life needs moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector displays with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this characteristic because every colour is delivered at the same time. DLP builders have come up with 3DLP solutions using 3 chips to resolve the colour break up error, but the price tag of these projectors make them impractical for most businesses and consumers.

Another point of difference between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and recall when they taught you how various colours of light refract differing amounts when directed through the same lens. The downfall with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. Generally with a DLP projector, some extra yellow colour will be projected above and a superfluous blue will show below something as simple as a lone black line. While being built LCD projectors can be adapted to take away these effects on the projected image, because each colour is directed on its own LCD panels.

The one true plus (excluding price) with buying a DLP projector is its smaller total size and weight. However, this is only relevant with regard to transport and has to be traded off against the image advantages of LCD projectors. If the outcome of the picture quality is important to you, then the answer is simple. Go for an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

2010 July 16

As the Dutch came to preeminence in sea power during the 17th century, the initial yacht had been a pleasure craft used mostly by royalty and then by the burghers on the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private matches. English yachting began 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 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, ruled 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 punt. Yachting was found to be classy among the affluent and nobility, but after that point the fashion did not last.

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

Yacht racing was seen in some organized fashion on the Thames in the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it came to be known as 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 society had been formed at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the continuing setting of British yacht racing. The organisation at Cowes became the Royal Yachting Club, again at the rise of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing races for large stakes were held, and the social life was splendid. Eventually Royal Yachting Club boats were raised in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English took control. Sailing was for the most part for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a standard of luxury and sophistication for the later yachts in that area from the late 19th century. The first enduring American yacht association, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts were within the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The craft of large yachts was initially greatly impacted by the victory of America, which was created by George Steers for a association led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. Early yachts were not designed and crafted in a contemporary sense, with merely a model for an outline. Not until the latter half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the use of the science of aerodynamics do for the structure of sails and rigging what such science had earlier done for hulls.

Because most of all sailboats were individually built, there was a need for handicapping boats as this was before the one-design class boats were made. Thus, a rating rule came into being, which resulted in the International Rule, accepted in 1906 and amended in 1919. Today, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing such boats can be had on an even basis with no handicapping necessary. A perfect example is the standard International America’s Cup Class adopted for participants in the 1992 America’s Cup race.

As long as yachting was done largely for the aristocracy and the affluent, money was no object, and the size of boats increased, in both length and weight. The rise and preference of smaller craft occurred in the latter 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small boats. Later in the 20th century, particularly after World War II, smaller racing and leisure craft became more common, down to the dinghy, a favoured 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
Following the decade 1840–50, when steam started to emulate sail power in market boats, the steam engine, and later the internal-combustion engine, were increasingly favoured in personal vessels. Bigger power yachts were developed to a high element, and long-distance travel became a preferred activity of the affluent. The first power yachts were paddle-wheel boats; they then made way to those powered by the wholly submerged screw or propeller sort of propulsion. As well as naval and merchant yachts, auxiliaries with both sail and power were the yacht standard for several years. By the later half of the 20th century, many yachts were still auxiliaries, but the large part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of more sizeable steam yachts. Conspicuous among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of more than 150. The Mayflower, purchased 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 bigger and more dependable internal-combustion engines were developed, many big yachts started using them for power. The establishment of the diesel engine, using heavy oil for fuel, progressed from World War I. From the decade following, bigger power-yacht building blossomed, climaxing in the Orion (1930) at 3,097 tons. From that time the best auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power yachts lessened after 1932, and the trend from then was toward smaller, less pricey yachts. After World War II, a lot of small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting had become a widespread beloved sport enjoyed by thousands of yachtsmen who are actually manning and upkeeping their own small pleasure yachts. The number of craft and sailors increased steadily, not only in the traditional locations by the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

2010 July 8

Taxes are categorized by the effect they have on the placement of income and wealth. A proportional tax is a kind that applies the same relative onus on every taxpayer—i.e., in the case where tax liability and income increase in the same scale. A progressive tax is characterized by a greater than proportional growth in the tax liability in regard to the increase in income, and a regressive tax is recognised by a less than proportional growth in the comparative liability. Ergo, progressive taxes are regarded as fighting inequity in income distribution, whereas regressive taxes may have the effect of increasing these inequalities.

The taxes that are normally regarded as progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, might become less so for the upper-income demographic—particularly if a taxpayer is permitted to lessen his tax base by nominating deductions or by removing some particular income components from his taxable income. Proportional tax rates which are applied to lower-income classes would also be more progressive if personal exemptions are claimed.

Income measured over a given year does not definitely offer the best measure of taxpaying ability. For example, transitory rises in income could be saved, and during temporary declines in income a taxpayer could decide to finance consumption by reducing savings. Ergo, if taxation is made comparable with “permanent income,” it would be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are generally regressive, because the spread of one’s income consumed or spent on specific goods decreases as the level of personal income rises. Poll taxes (also called head taxes), calculated as a set amount per capita, obviously are regressive.

It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of the lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In regarding the economic effects of taxation, it is essential to differentiate between several points of tax rates. The statutory rates include those nominated in legislation; generally these are marginal rates, but occasionally they are mean rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income grows by one dollar. Thus, if tax burden increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations usually contain graduated marginal rates—i.e., rates that rise as income grows. Structured analysis of marginal tax rates are required to consider provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points greater than nominated by the statutory rates. Since marginal rates signify how after-tax income is changed in response to changes in before-tax income, they are the important ones for considering incentive effects of taxation. It is even more complicated to know the marginal effective tax rate to apply to income from business and capital, because it may rely 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 nil under a consumption-based tax.

Average income tax rates indicate the percentage of total income that is paid in taxation. The pattern of average rates is the one that is in consideration for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates commonly rise with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; on the other side of things, preferential treatment of income received predominantly by high-income households could swamp these effects, allowing regressivity, as displayed by average tax rates that lessen as income increases.

The Development of Data Projectors

2010 June 30
by squadron

The LCDs put in projection systems are usually small reflective or transmissive panels illuminated by a bright arc lamp source. A series of lenses magnifies the reflected or transmitted image then casts it onto the screen. In front-projection systems the LCD is situated on the same area of the screen as the viewer, but in rear-projection systems the screen is lit from behind. Projectors of more expense and capability can use three separate LCD panels, creating separate red, green, and blue images that mesh to reflect a coloured picture on the screen.

The increasing demand for pictographic displays has had a particular emphasis on the switching speed of liquid crystals. This has necessitated the invention of devices build with smectic liquid crystals, certain ones of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most sophisticated smectic device. With it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal has optically active molecules, and a scarcely perceptible outcome of the optical activity and the tilt of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, likeable 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. Thus, there exists a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The consequential change in optical properties can make a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been commercialized for big passive-matrix presentations, but their cost and complex nature has stopped them from having any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as elements in projection systems or as viewfinders in digital cameras. Their speedy response allows them to be employed in time-sequential colour systems, in which dear colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick pace (about 100 cycles every second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods then to a nontransmissive state in the blue period, creating 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

From each of the furniture objects, the chair could be the imperative one. While many other items (save for the bed) are created to support objects, the chair supports the human form. The term chair is meant to be regarded here in the general sense, from stool to throne to derivative kinds like a bench and sofa, which should be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently defined.

The social history of the chair is as intriguing as its history as an art and craft. The chair is not simply a physical support and an aesthetic craft; it can also be a signifier of social ranking. At the old royal courts there were important connotations between being led to a chair with arms, sitting on a chair with a back but without arms, and having to squat on a stool. Since the 20th century, a director’s and manager’s chair has been regarded as a symbol of superior position, as well as in democratic governments the speaker sits on a higher floor.

As its furniture creation, the chair holds a wealth of various forms. There are chairs created to match man’s age and physical capabilities (the high chair, the wheelchair) and to indicate his rank in society (the executive chair, the throne). In past days there were chairs used for birth (birth chairs); since the 20th century, there have been chairs to die in (the electric chair). We have chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern living has developed new chairs in automobiles and aircraft. All of these chair shapes has been evolved to fit to different human requirements. For its close association with man, the chair comes to its full advantage only when being utilised. Though it doesn’t make a difference to one’s appreciation of a cupboard or a chest of drawers if there is anything inside or not, a chair is best seen and evaluated by a person utilising it, because chair and sitter suit one another. Thus the different areas of a chair are given labels likened to the parts of our human shape: arms, legs, feet, back, and seat.

Because the fundamental work of your chair is to support our body, its credit is judged firstly for how well it fulfills this practical job. In the build of the chair, the maker is bound in some static law and principal measurements. Within these rules, however, the chair designer has great freedom.

The history of the chair lasted an era of several thousand years. There are civilizations that held individual chair forms, expressions of the foremost work in the industries of handling and aesthetics. In these such cultures, a mention 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 upshot of skilled craft, were known from tomb findings. The first one of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs shaped like those of an animal, a curved seat, with a sloping back supported over vertical stretchers. In this design a solid triangular construction was created. There was to all appearances no particular difference in the structure of Egyptian thrones and chairs for ordinary peasantry. The simple change exists in the kind of ornamentation, in the particulars of pricey inlays. The Egyptian folding stool probably was crafted to be an easily stored seat for officers. As a camp stool this stool stayed during much later days. But the stool also then played the task of a ceremonial seat, its mechanical history as a folding stool ignored or forgotten. This can from today’s evidence be observed, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were made in the construction of folding stools but are not able to be folded because the seats were worked of wood. The easy make of the folding stool, being of two frames that spin on metal bolts and bear a seat of leather or fabric fastened between them, also appeared but somewhat later as the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of these is the folding stool, of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is seen not as any ancient object still extant but seen in a variety of pictorial material. The significant kind is the klismos posited on the Hegeso Stele at the Dipylon burial area outside Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of them are visible. These unique legs were presumably manufactured out of bent wood and were therefore subjected to great pressure under the weight of the sitter. The joints joining the legs to the frame of the seat were therefore super durable and were particularly signified.

The Romans embued the Greek chair; a number of models of seated Romans display chairs of a more heavyset and in appearance rather more crudely constructed klismos. Both kinds, the light and heavy, were seen again as part of the Classicist epoch. The klismos chair can be seen in French Empire design, in English Regency, and in special brands of profound individuality within Denmark and Sweden circa 1800.

China
The ancestry of the chair in China can not be charted as far back as chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed collection of sketches and paintings had been protected, displaying the interior and outside of Chinese households and the designs of furniture. Another preservation since the 16th century are a collection of chairs crafted of wood or lacquered wood, that bear an interesting familiarity to styles of past chairs.

Just as in Egypt, two iconic chair forms existed in China: a chair with four legs and a folding stool. That four-legged chair has been seen both with or without arms however never without its square seat and straight stiles (standing side supports) to firm the back. In one style, it has been found, the stiles had been marginally curved on top of the arms so as to conform to the form of the S-shaped back splat (the centre upright of its back). The three areas had been mortised onto the yoke-like top rail. While the design of the Chinese back splat then had an inspiration for English chairs of the Queen Anne period, wooden pieces that only to a restricted extent reinforce corner joints (and then were loose to top it off) signify a feature exclusive to Chinese chairs. The four legs pass through the seat frame, which finishes about the rounded staves. Members are round in section or is given rounded edges—references maybe to the bamboo tradition. The seat is unpleasant to sit in and may have had a plaited texture. These chairs demanded of the sitter to stay stiff and upright; if too much pressure is pushed on the back, the chair has a tendency to fall. In patriarchal Chinese houses of this era armchairs probably were only for older individuals, for they were greatly esteemed.

The Chinese folding stool is thought to have come to China from the West. It does not vary so very much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is elegantly held to the two legs of the stool by using a curved member, which is often possessing metal mounts. From a Western perspective the resulting effect of both furniture items is stylized. The construction and decoration elements are combined in a way that is both naïve and refined. The pieced-together appearance is a result of the fact that the individual members do not seem to have been fixed with either glue or screws, but had been mortised into one another and held in its place in the style 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 kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in the layers, stitched to produce a pattern of tiny pads. The front board and a corresponding board in the back could be folded after unscrewing some tiny iron hooks. In this way the chair was a readily portable piece of furniture while traveling which, in the same era, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be found 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. Although this design of chair is also found in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not believed that the style actually started in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of slim shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in vast numbers, as evidenced from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up along a wall. The form asserts itself with its elegant proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, as developed in Paris around 1750—conquered most of Europe and has been imitated or copied in the mid-20th century. The model owes its popularity to a combination of comfort and elegance. The seat adheres to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions are found between seat frame, legs, and back cover all the joints, which are constructed on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of quite thick measurements; but all the members are deeply molded, all extraneous wood has been removed, and finer items would be further embellished with highly delicate and decorative engraving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for any upholstery on the seat, back, and armrests; canework is occasionally used as an alternative to upholstery.

English chairs in the 18th century were more varied in form than the French. The French manner for stylistic uniformity, which lead from the aristocratic circles in Paris and Versailles through most of France and won favour 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 commonly known 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, hint that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

2010 June 23
by squadron

Bookkeeping is the recordkeeping of the money values of the transactions of a business. Bookkeeping creates the numbers from which accounts are prepared but is a separate process, preliminary to accounting.

Essentially, bookkeeping grants two areas of information: (1) the current value, or equity, of the enterprise and (2) changes in value—profit or loss—taking position in the business over a given time.

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

Evidence of financial and numerical records can be seen for just about every civilization with a commercial background. Records of commercial contracts have been discovered in the ruins of Babylon, and accounts for both farms and estates had been made in ancient Greece and Rome. The double-entry way of bookkeeping came with the furthering of the business republics of Italy, and tutorial books for bookkeeping were developed during the 15th century in some Italian cities.

During the late 18th and early 19th centuries, the Industrial Revolution permitted a notable stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a must-have. The ancestry of bookkeeping, in fact, closely resembles the history of commerce, industry, and government and, in part, assisted in shaping it. The global market of industrial and commercial activity demanded greater cosmopolitan decision-making procedures, which in its turn called for more sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government legislature became more detailed and resulted in higher demand for information; business entities had to show available information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the requirement for bookkeeping for their inner departmental operations went up.

While bookkeeping processes can be very multifaceted, it is all based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, etcetera), and the ledger must have the record of individual accounts. The daily records from the journals are put in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are created from the trial balance posted within the ledger. The job of the income statement or profit-and-loss statement is to provide an analysis of any changes that took place in the ownership equity resulting due to the events of the period. The balance sheet provides the financial position of the entity at any particular date derived from 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 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 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.
