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

by Brisbane Honda

The most common question customers ask when acquiring a new projector for the home, office, or classroom is: should I purchase an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many brands and models available, it can be challenging for the buyer to pick between the two technologies. The fact is that LCD projectors give superior image quality and colour accuracy. The next paragraph tells you why DLP projectors struggle with projecting an equal level of image quality.

Imagine a set of blinds in your household for your bedroom window. By twisting a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. This is exactly how an LCD projector operates. Each pixel operates like a unique shutter on a set of blinds to either pass 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 functions to either reflect light or block it.

How the light source is processed from the point at which the projector is switched on to when the image reaches your screen is vitally significant with regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by shining each pixel on and off. The pixels are then projected in a glass prism to create the projector image. Something important to understad about LCD projectors is that all three colours are delivered onto your projected surface all at the same time. The way a DLP projector functions is very different and even the way an image shows up is not the same. With DLP, white light from the lamp is sent 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 requires 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 sent in sequence on the screen, one colour at a time. The viewer’s eyes will then combine each coloured element of the image into a single whole image. In LCD projectors, all colours are available all the time to form top brightness and superb colour accuracy. In DLP, only one colour is available at once, and so causing lower colour brightness and accuracy. Some DLP developers have added a white segment for the colour wheel to improve brightness generally, but this then lessens colour accuracy.

I see in forums all the time that DLP provides a higher contrast ratio and ergo must be superior quality. For those who are 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 machine is capable of. DLP projectors do provide high contrast specifications as compared to many LCD projectors. Initially, this can seem to be an advantage, however, in real life, the true black level is determined by the ambient light in the room while the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to view includes moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because the colours are projected at the same time. DLP manufacturers have created 3DLP solutions using 3 chips to solve the colour break up problem, but the cost of these projectors make them almost impossible for many businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Think back to high school science, and recall when they taught you how the different colours of light refract different amounts when directed through the same lens. The disadvantage 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 different ways. Generally with a DLP projector, a superfluous yellow colour will be projected above and a spill of blue will come through below an image as simple as a straight black line. In manufacturing LCD projectors can be adapted to minimize these effects on the projected image, because each colour is refracted on its own LCD panels.

The sole real buy point (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant for mobility and needs to be traded off against the image superiority of LCD projectors. If the outcome of the picture quality is crucial to you, then the decision is a no-brainer. Go with an LCD projector! LCD projectors will consistently make bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

by Brisbane Honda

As the Dutch rose to preeminence in sea power during the 17th century, the initial yacht had been a leisure craft used first by royalty and secondly by the burghers for the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English royalty in 1660, the city of Amsterdam gave him 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, sovereign 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting rose as classy among the wealthy and aristocracy, but after that point the habit did not last.

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

Yacht racing began in some organized manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it came to be named 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 society had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent - the strait between the mainland and the Isle of Wight - the continued site of British racing. The society at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing races for high bids were held, and the club life was lovely. It came to be that the Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English had power. Sailing was for the most part for fun and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in those waters from the late 19th century. The first persisting American yacht association, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The craft of large yachts was initially heavily impacted by the victory of America, which was drawn by George Steers for a group led 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. The first yachts were not designed and manufactured in today’s sense, with just a model being used. Not until the later half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the employment of the science of aerodynamics do for the design of sails and rigging what it had already done for hulls.

Because most of all sailboats had been individually manufactured, there arose a need for handicapping boats before the one-design class boats were designed. Therefore, a rating rule came into being, which resulted in the International Rule, accepted in 1906 and amended in 1919. Today, one of the most 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 standard dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing such boats can be held on an even keel with no handicapping required. A prime example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting was an activity primarily for the royal and the affluent, expense was no issue, and the size of boats grew, in both length and weight. The promotion and desire of smaller boats came in the latter 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 journey 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 yachts. Later in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a popular 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, when steam began to emulate sail power in commercial craft, the steam engine, and later the internal-combustion engine, were favoured increasingly in personal craft. Sizeable power yachts were progressed to a high standard, and long-distance cruising was a favourite pastime of the affluent. The early power yachts were paddle-wheel boats; these then gave way to boats powered by the wholly submerged screw or propeller type of propulsion. As well as naval and merchant yachts, auxiliaries carrying both sail and power were the yacht archetype for many years. By the latter half of the 20th century, many yachts were still auxiliaries, but the majority were exclusively power yachts that had gasoline or diesel engines.

During the last decade of the 19th century there was a push in the manufacture of more sizeable steam yachts. In particular 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, 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 larger and better quality internal-combustion engines were created, many big yachts began using them for power. The development of the diesel engine, using heavy oil for fuel, advanced during World War I. From the decade following, large power-yacht creation flourished, climaxing in the Orion (1930) at 3,097 tons. In that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of larger power craft declined from 1932, and the style thereafter was toward smaller, less costly yachts. From World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. In the late 20th century, yachting is a globally popular competition enjoyed by thousands of yachtsmen individually manning and maintaining their own small pleasure boats. The amount of yachts and sailors is increasing steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

by Brisbane Honda

Taxes are categorized by the effect they have on the distribution of income and wealth. A proportional tax is one that imposes the same relative onus on each taxpayer—i.e., in the case where tax liability and income grow in relative proportion. A progressive tax is characterized by a larger than proportional increase in the tax burden in relation to the increase in income, and a regressive tax is characterizable by a less than proportional rise in the comparative onus. Therefore, progressive taxes are seen as removing inequalities in income distribution, whereas 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 categorically progressive, however, can become less so in the upper-income group—in particular if a taxpayer is permitted to lower his tax base by nominating deductions or by taking some income parts from his taxable income. Proportional tax rates that are applied to lower-income categories will also be more progressive if exemptions of a personal nature are claimed.

Income measured over a given period might not absolutely provide the most accurate measure of taxpaying requirement. For example, transitory rises in income may be saved, and in temporary declines in income a taxpayer could elect to pay for consumption by taking from savings. So, if taxation is regarded along with “permanent income,” it would 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 dissemination of personal income consumed or spent for a specific good decreases as the level of personal income grows. Poll taxes (aka head taxes), calculated as a fixed amount per capita, obviously are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to uncertainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden lays crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In regarding the economic purpose of taxation, it is essential to differentiate between various ideas of tax rates. The statutory rates include those specified in the law; usually these are marginal rates, but occasionally they are average rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income is increased by one dollar. Thus, if tax burden grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation often contain graduated marginal rates—i.e., rates that grow as income increases. Heavy analysis of marginal tax rates should regard provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than nominated in the statutory rates. Since marginal rates signify how after-tax income is changed 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 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 shows that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates indicate the portion of total income that is paid in taxation. The pattern of average rates is the one that is relevant for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally grow with income, both because personal allowances are granted for the taxpayer and dependents and because marginal tax rates are graduated; on the other side of things, preferential treatment of income received for the most part by high-income households can swamp these effects, allowing regressivity, as displayed by average tax rates that fall as income increases.

The Development of Data Projectors

by Brisbane Honda

The LCDs put for projection systems are typically small reflective or transmissive panels lit by a powerful arc lamp source. A number of lenses enlarges the reflected or transmitted image and casts it on the screen. In front-projection systems the LCD is located on the same area of the screen as the viewer, although in rear-projection systems the screen is lit from behind. Projectors of greater cost and performance might use three discrete LCD panels, reflecting separate red, green, and blue images that mesh to make a coloured picture on the screen.

The increasing need for pictographic displays has had a growing emphasis on the switching speed of liquid crystals. This has required the invention of objects utilizing smectic liquid crystals, some kinds of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most complex smectic device. Within it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are on a slant, as displayed in the figure. The host liquid crystal contains optically active molecules, and a scarcely perceptible turn up of the optical activity and the shape of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, similar 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. 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 corresponding sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The corresponding change in optical properties can create a change from light to dark when one or more polarizers are employed.

SSFLC devices have been marketed for larger passive-matrix presentations, but their cost and detail has hindered them from making any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be employed in time-sequential colour systems, in which high cost colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast succession (approx 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods and then to a nontransmissive state for the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

by Brisbane Honda

Out of each of the furniture pieces, the chair could be the imperative one. While most of the other forms (save the bed) are intended to support objects, the chair supports a human form. The term chair is meant to be used here in the larger sense, from stool to throne to complex pieces including the bench and sofa, which can be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinuishable.

The social history of the chair is as intriguing as its history as a creative art. The chair is not merely a physical support or an aesthetic craft; it is historically an indicator of social ranking. Within the old royal courts there were significant distinctions between being seated on a chair with arms, or a chair with a back but without arms, or having to utilise a stool. In the past century, the director’s or manager’s chair has been a symbol of superior rank, and in democratic governments the speaker sits on a raised floor.

As its furniture construction, the chair can be employed for a number of variations. There are chairs structured to attend to man’s age and physical form (the high chair, the wheelchair) and to connotate his rank in society (the executive chair, the throne). In past times there were chairs for birthing (birth chairs); from the 20th century, there have been chairs used for ending life (the electric chair). We design chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern living has developed unique chairs for use in automobiles and aircraft. Each of these chair forms has evolved to match to growing human requirements. Because of its close link with man, the chair exists to its full advantage only when utilised. Although it does not make a difference to one’s appreciation of a cupboard or a dresser drawers whether there might be items inside or not, a chair is best seen and judged with a person sitting on it, because chair and sitter suit the other. Thus the different limbs of a chair have been named likened to the parts of a human body: arms, legs, feet, back, and seat.

Because the elementary purpose of the chair is to support the body, its credit is valued primarily from how suitably it fulfills this practical job. In the structure of the chair, the designer is bound under some static laws and principal measurements. Through these limits, however, the chair creator has marvellous freedom.

The history of the chair lasted dates of several thousand years. There were peoples that made iconic chair forms, as expressions of the topmost craft in the spheres of technique and creativity. From these peoples, special 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of careful craft, are now known from tomb discoveries. The first one of these two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair has four legs designed not unlike those of a designated animal, a curved seat, and with a sloping back supported over vertical stretchers. In this design a durable triangular structure was made. There was in our understanding no noteworthy difference in the structure of Egyptian thrones and chairs for regular peasantry. The real variation lies in the complexity of ornamentation, in the particulars of expensive inlays. The Egyptian folding stool likely was designed for an easily stored seat for soldiers. As a camp stool the type stayed until much later periods. But the stool then also was created as the character of a ceremonial seat, its mechanical job as a folding stool simply forgotten. This can today be observed, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but aren’t able to be folded because the seats are made of wood. The plain build of the folding stool, composed of two frames that cycle on metal bolts and have a seat of leather or fabric set between them, then came again some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of those is the folding stool, from ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not from any ancient item still existing but as in a wealth of pictorial evidence. The better known is the klismos seen on the Hegeso Stele at the Dipylon burial place in outer Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those would be visible. These curving legs were presumably manufactured in bent wood and were thus subjected to great pressure under the weight of the sitter. The joints securing the legs to the frame of the seat would have had to be therefore extremely strong and were clearly denoted.

The Romans borrowed from the Greek design; evidence of models of seated Romans display chairs of a more heavyset and apparently slightly less delicately designed klismos. Both designs, the light and heavy, were revived during the Classicist era. The klismos chair is used in French Empire styles, in English Regency, and in some kinds of marked iconicism within Denmark and Sweden circa 1800.

China
The ancestry of the chair in China cannot be followed as long as that of Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) a full folio of images and artworks was kept safe, detailing the interior and outer parts of Chinese households and the designs of furniture. Also kept of the 16th century are a trove of chairs constructed from wood or lacquered wood, that show an interesting similarity to images of previous chairs.

As was the case in Egypt, there were two fundamental chair forms in China: a chair having four legs and a folding stool. That four-legged chair has been constructed both with and without arms but always having a square seat and straight stiles (straight side supports) to hold up the back. In one kind, it has been seen, the stiles were slightly curved by the arms for the purpose of conform correctly to the shape of the S-shaped back splat (the basic upright of the back). The three areas were mortised on the yoke-like top rail. Though the innovation of the Chinese back splat then had an inspiration for English chairs within the Queen Anne period, wooden pieces that just to a restricted limit reinforce corner joints (and are loose in the result) are an element particular to Chinese chairs. The four legs sit through the seat frame, which ends over the rounded staves. All members are round in section or has rounded edges—references as may be to the bamboo tradition. The seat is uncomfortable and might have had a plaited seat. These chairs demanded of the sitter to be stiff and upright; when too much weight is exerted on the back, the chair has a way of collapsing. In patriarchal Chinese homes of this period armchairs presumably were kept for older people, for they were held in great esteem.

The Chinese folding stool is thought to have taken to China from the West. It is akin that much from the Egyptian or Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is intricately fixed to the two legs of the stool by using a curved member, which is usually provided with metal mounts. From a Western viewpoint the overall effect of both of these furniture styles is stylized. The manufacture and decoration parts are combined in a style that is at the same time naïve and refined. The pieced-together appearance is an upshot of the way that the individual items do not seem to have been affixed with either glue or screws, but were mortised with one another and locked into place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its name on the chair. Artworks show a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between, stitched to bring out a pattern of small pads. The front board and a related board in the back could be folded after unscrewing some small iron hooks. Therefore the chair was a readily portable piece of furniture for traveling which, during the same era, held the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is evidenced in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair might also be made in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not certain that the design actually originated in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of slender dimensions; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in considerable amounts, as evidenced from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up against a wall. The form asserts itself with its harmonious 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 style—that is, as created in Paris around 1750—disseminated over most of Europe and was imitated or copied during the mid-20th century. The chair owes its popularity to a combination of relaxation and elegance. The seat conforms 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 solidly on craftsmanlike principles despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of fairly thick density; but all the members are deeply molded, all extra wood has been removed, and more expensive examples might be further embellished with very delicate and decorative woodwork. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for all of the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used instead of upholstery.

English chairs of the 18th century were more varied in design than the French. The French manner for stylistic uniformity, which spread from the aristocratic circles in Paris and Versailles over most of France and became the preference in large 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
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, suggest that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

by Brisbane Honda

Bookkeeping is the charting of the money values of the function of a business. Bookkeeping gives the details from which accounts are drafted but is a previous process, required prior to accounting.

Fundamentally, bookkeeping grants two parts of information: (1) the current value, or equity, of a business and (2) the changes in value—profit or loss—taking place in the business from a singular period of time.

Management officials, investors, and credit grantors all have to have this kind of information: management so as to assess the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to understand the upshot of business operations and make decisions about buying, holding, and selling securities; and credit grantors so as to regard the financial statements of a business in deciding whether to allow a loan.

Evidence of financial and numerical charts are uncovered for just about every group of people with a commercial background. Records of trade contracts have been discovered in the ruins of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The dual-entry process of bookkeeping started with the development of the entrepeneurial republics of Italy, and manuals for bookkeeping were produced within the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial books a must-have. The ancestry of bookkeeping, in fact, reflects closely the history of commerce, industry, and government and, in some part, assisted in forming it. The worldwide market of industrial and commercial activity called for better cosmopolitan decision-making methodology, which then called for greater 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 firms had to have available information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the need for bookkeeping for their own operations increased.

Although bookkeeping processes can be very detailed, it is all based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger has the details of individual accounts. The daily records from the journals are entered in the ledgers.

Each month, by general practice, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to show an analysis of any changes that took place in the ownership equity because of the events of the period. The balance sheet displays the financial position of the entity at a particular point in time derived from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

by Brisbane Honda

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.
