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

The most common question asked when looking for a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different types available, it can be confusing for the buyer to choose between the two technologies. Ultimately LCD projectors provide superior image quality and colour accuracy. The next part of this article tells you why DLP projectors struggle with reproducing an equal level of image quality.

It’s like a set of blinds in your house for your bedroom window. By pulling on a rod you can have the shutters open or closed, according to if you want to let light in or not. And such is exactly how an LCD projector works. Each pixel operates like a single 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 the pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the time the projector is switched on to when the picture reaches your screen is vitally important to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by separating it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to deliver the projector image. Something to understad about LCD projectors is that all three colours are sent onto your projected surface simultaneously. The way a DLP projector functions is widely different and even how an image shows up is not the same. With DLP, white light from the lamp is sent through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of making an image creates a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to construct 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 draw each coloured element of the image into a complete image. From LCD projectors, all colours are available all the time to form the best brightness and spectacular colour accuracy. In DLP, just one colour is available at once, and so causing lower colour brightness and accuracy. Some DLP developers have put a white segment in the colour wheel to improve brightness overall, but this also damages colour accuracy.

I see in forums all the time that DLP has a higher contrast ratio and as such must be better 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 projector is capable of. DLP projectors do have high contrast specifications compared to a majority of LCD projectors. At one glance, this must be a benefit, however, in real life, the true black level is determined by the ambient light in the room where the projector is in use. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you plan to project includes moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most often seen artifact that a DLP projector forms 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 projected. LCD projectors do not have this downside because the colours are delivered simultaneously. DLP manufacturers have come up with 3DLP solutions using 3 chips to fix the colour break up artifacts, but the price tag of these projectors make them impractical for many businesses and consumers.

Another variance between LCD and DLP is how they compensate for the refractive qualities of light. Jump back to high school science, and they taught you how the various colours of light refract different amounts when directed through the same lens. The downfall 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 not the same and refract light differently. Usually with a DLP projector, a spill of yellow colour will be projected above and a superfluous blue will show below something as simple as a single black line. In manufacturing LCD projectors can be adapted to reduce these effects on the projected image, as each colour is projected on a separate LCD panels.

The isolated actual plus (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to mobility and cannot be traded off against the image plusses of LCD projectors. If the result of the picture quality is important to you, then the answer is easy. Take an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the initial yacht became a pleasure craft used initially by royalty and later by the burghers for the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, borne from private challenges. 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 gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting rose as fashionable for the affluent and nobility, but after that time the habit did not last.

The first yacht group in the British Isles, the Water Club, was formed at about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and had much naval panoply and gravity. The closest thing to racing boats was the “chase,” for which the “fleet” pursued an imagined enemy. The club persisted, mostly as a social club, until 1765, and in 1828, after conglomerating with other groups, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some ordered manner 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 was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht association 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 continuing location of British racing. The organisation at Cowes became the Royal Yachting Club, again at the accession of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing matches for high bets were held, and the club life was lovely. Ultimately Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and persisted when the English took power. Sailing was mostly for leisure and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a minimum of luxury and sophistication for the later yachts in the 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 instigated the New York Yacht Club while on board his schooner Gimcrack.

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

Because most of all sailboats had been individually custom-built, there arose a desire for handicapping boats before the one-design class boats were made. Therefore, a rating rule was decreed, which is found in the International Rule, taken on in 1906 and edited in 1919. In the present day, one of the 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 dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for these boats can be held on an even keel with no handicapping at all. A great example is the generic International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

For the time that yachting belonged mostly for the royal and the wealthy, expense was no problem, and the size of boats developed, in both length and weight. The rise and popularity of smaller boats happened 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 trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the seaworthiness of less sizeable yachts. Thereafter in the 20th century, particularly after World War II, smaller racing and leisure yachts became more common, down to the dinghy, a favoured 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
Post the decade 1840–50, at which point steam started to take the place of sail power in public vessels, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure vessels. Large power yachts were developed to a high standard, and long-distance travel turned into a preferred occupation of the wealthy. The earliest power yachts were paddle-wheel boats; these then gave rise to boats powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant vessels, auxiliaries carrying both sail and power were the yacht fashion for several years. By the later half of the 20th century, several yachts were still auxiliaries, but the majority were only power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the manufacture of large steam yachts. Notably within these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of at least 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 gave active service during World War II.

As more sizeable and more dependable internal-combustion engines were created, many big yachts were using them for power. The development of the diesel engine, with heavy oil for fuel, progressed during World War I. In the decade following that, bigger power-yacht manufacture grew, hitting a climax in the Orion (1930) at 3,097 tons. During that point the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of larger power yachts declined from 1932, and the fashion thereafter was for smaller, less expensive yachts. After World War II, lots of small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally popular activity enjoyed by thousands of yachtsmen individually owning and maintaining their own small leisure yachts. The number of craft and sailors has increased steadily, not only in the traditional areas along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the impact they have on the allocation of income and wealth. A proportional tax is the kind of tax that places the same relative liability on all taxpayers—i.e., when tax liability and income move in the same levels. A progressive tax is characterized by a more than proportional growth in the tax liability in relation to the increase in income, and a regressive tax is characterizable by a less than proportional growth in the relative liability. Hence, progressive taxes are regarded as removing inequity in income distribution, while regressive taxes are found to cause an increase in these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, may become less so within the upper-income group—particularly if a taxpayer is able to lessen his tax base by claiming deductions or by removing particular income aspects from his taxable income. Proportional tax rates if applied to lower-income demographics could also be more progressive if exemptions of a personal nature are declared.

Income measured over the period of a year does not necessarily give the most suitable measure of taxpaying requirement. For example, transitory growth in income can be saved, and during temporary declines in income a taxpayer could select to provide for consumption by reducing savings. Ergo, if taxation is compared alongside “permanent income,” it would be less regressive (or more progressive) than when made comparable with annual income.

Sales taxes and excises (excepting those on luxuries) tend to be regressive, because the spread of personal income consumed or spent on specific goods lessens as the level of personal income grows. Poll taxes (also known as head taxes), calculated as a standard amount per capita, clearly are regressive.

It is difficult to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of the lack of certainty surrounding 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 crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In analysing the economic purpose of taxation, it is relevant to distinguish between differing ideas of tax rates. The statutory rates will include those dictated in the law; usually these are marginal rates, but for some cases they are median rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income grows by one dollar. Hence, if tax liability rises 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. Careful analysis of marginal tax rates are required to regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points greater than nominated in the statutory rates. Since marginal rates specify how after-tax income changes in response to changes in before-tax income, they are the appropriate ones for considering incentive effects of taxation. It is even more complicated to understand the marginal effective tax rate applicable to income from business and capital, because it may be reliant 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 zero under a consumption-based tax.

Average income tax rates show the fraction of total income that is taken in taxation. The pattern of average rates is the one that is important for judging 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 also due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households can swamp these effects, producing regressivity, as shown by average tax rates that lessen as income increases.

The Development of Data Projectors

The LCDs put in projection systems are usually small reflective or transmissive panels illuminated by a powerful arc lamp source. A number of lenses expands the reflected or transmitted image and casts it on a screen. With front-projection systems the LCD is situated on the side of the screen as the viewer, while in rear-projection systems the screen is illuminated from behind. Projectors of higher expense and capacity sometimes be found with three distinct LCD panels, reflecting separate red, green, and blue images that mesh to make a coloured display on the screen.

The growing requirement for film displays has put a particular emphasis on the switching speed of liquid crystals. This has demanded the creation of devices build with smectic liquid crystals, certain types of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most complex smectic device. Inside it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and in the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal possesses optically active molecules, and a scarcely perceptible result of the optical activity and the angle of the molecules is the appearance 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 must be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly paired up 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 resultant change in optical properties can effect a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been marketed for big passive-matrix presentations, but their high cost and complexity has impeded them from creating any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some possibility for use as aspects 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 with a coloured backlight that flashes red, green, and blue in fast pulsing (about 100 cycles in a second). For example, the liquid crystal may be switched to a transmissive state between the red and green periods and to a nontransmissive state for the blue period, creating the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture needs, the chair might be the imperative one. While the majority of other objects (save for the bed) are intended to support objects, the chair supports our human form. The term chair is intended to be viewed here in the wider sense, from stool to throne to derivative types like a bench and sofa, which might be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly defined.

The social history of the chair is as exciting as its history as a creative art. The chair is not simply a physical support or an aesthetic object; it is also semiotic of social placement. In the old royal courts there were social signifiers between being seated on a chair with arms, on a chair with a back but without arms, or having to sit on a stool. In the recent century, the director’s and manager’s chair has developed a symbol of superior dignity, as well as in democratic government meeting the speaker sits on an elevated level.

In a furniture form, the chair can be utilised for a range of variations. There are chairs structured to suit man’s age and physical condition (the high chair, the wheelchair) and to connotate his standing in society (the executive chair, the throne). Since past times there were chairs for birthing (birth chairs); from the 20th century, there have been chairs for ending life (the electric chair). We make chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded up, chairs on wheels, and chairs on runners.

Our modern lifestyle has developed special chairs in automobiles and aircraft. Every one of these chair kinds has been adapted to fit to changing human needs. Due to its unique connection with man, the chair exists to its full importance only when being used. Though it does not make any difference to one’s appreciation of a cupboard or a chest of drawers if there are things inside or not, a chair is understood best and fairly tested with a person sitting in it, because chair and sitter suit one another. Thus the different parts of a chair have been named corresponding to the parts of our human parts: arms, legs, feet, back, and seat.

Because the original job of a chair is to support our human body, its worth is evaluated firstly by how well it does fulfill this practical use. In the structure of the chair, the designer is limited in some static regulation and principal measurements. Inside these limitations, however, the chair creator has awesome freedom.

The history of the chair lasted over an era of several thousand years. There are peoples that created unique chair shapes, as expressive of the principal task in the industries of technique and art. From such cultures, a note 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 upshot of careful design, are today found from tomb discoveries. One of the two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have had four legs structured like those of some animal, a curved seat, and leading to a sloping back supported from vertical stretchers. In this way a solid triangular structure was crafted. There was to all appearances no significant difference in the construction of Egyptian thrones and chairs for regular non-royals. The simple variation exists in the kind of ornamentation, in the evidence of pricey inlays. The Egyptian folding stool in all probability was developed as an easily packed seat for army. As a camp stool this type continued during much later times. But the stool also then was designed as the character 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, formed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were in the construction of folding stools but can’t be folded as the seats were made from wood. The easy manufacture of the folding stool, being of two frames that cycle on metal bolts and support a seat of leather or fabric fastened between them, then appeared at some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of those is the folding stool, made of ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is recognised not from any ancient item still existing but in a large amount of pictorial objects. The better recognised is the klismos seen on the Hegeso Stele at the Dipylon burial location outside Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them can be shown. These creative legs were understood to be executed in bent wood and were likely to have been needed to bear great pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat would have been therefore very strong and were visibly signified.

The Romans adopted the Greek designs; designs of models of seated Romans are examples of a heavier and in appearance kind of less delicately designed klismos. Both styles, the light or heavy, were seen again as part of the Classicist era. The klismos chair can be found in French Empire chairs, in English Regency, and in some kinds of considerable originality around Denmark and Sweden during 1800.

China
The progression of the chair in China is not able to be traced as long as that of Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) a full folio of sketches and artworks had been protected, with images of the interior and exteriors of Chinese buildings and the designs of furniture. Also kept since the 16th century are a trove of chairs constructed of wood or lacquered wood, that display an astonishing resemblance to representations of ancient chairs.

Just as in Egypt, there were two iconic chair designs in China: a chair with four legs and a folding stool. This chair can be constructed both with or without arms but never missing a square seat and straight stiles (standing side supports) to firm the back. In one kind, though, the stiles could be delicately curved by the arms for the purpose of sit correctly with the form of the S-shaped back splat (the centre upright of its back). Each of the three areas are mortised into the yoke-like top rail. While the design of the back splat exercised an influence on English chairs of the Queen Anne period, wooden items that could merely to a restricted extent reinforce corner joints (and furthermore were loose as well) are a design particular to Chinese chairs. The four legs sit through the seat frame, which finishes about the rounded staves. All members are round in section or possesses rounded edges—references perchance to the bamboo tradition. The seat is not comfortable and may have had a plaited bottom. These chairs needed the sitter to be stiff and upright; for when too much pressure is exerted on the back, the chair has a way of toppling over. In patriarchal Chinese houses of this era armchairs presumably were allowed only for older members of the family, for they were respected greatly.

The Chinese folding stool is thought to have been brought to China from the West. It is not dissimilar so very much from the Egyptian and Scandinavian folding stools, but it has a difference in that the top rail is prettily affixed to the two legs of the stool in a curved member, which is more often than not seen with metal mounts. From a Western perspective the ultimate effect of both furniture designs is stylized. The constructive and decoration elements are combined in a manner that is simultaneously naïve and refined. The patched up appearance is an upshot of the manner that the individual parts do not seem to have been joined together by use of either glue or screws, but are mortised on one another and held in place 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. Artworks project a type of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to bring up a pattern of little pads. The front board and a related board at the back could be folded after unscrewing some tiny iron hooks. Therefore the chair was a readily portable piece of furniture for traveling which, during the same period, gave the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be displayed in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this type of chair can also be found in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not believed that the innovation actually was born in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slender measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in impressive quantities, as can be seen from one of Abraham Bosse’s engravings, in which there is a whole row of such chairs lined up by a wall. The form asserts itself by virtue of its elegant proportions and fine upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that is, as created in Paris around 1750—spread through most of Europe and has been imitated or copied into the mid-20th century. The chair owes this popularity to a combination of comfort and charm. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are constructed solidly on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them are constructed from wood of fairly thick dimensions; but all the members are deeply molded, all extraneous wood has been cut away, and finer items can be further embellished with intricately delicate and decorative engraving. The wood might 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 sometimes used as an alternative to upholstery.

English chairs from the 18th century were more varied in design than the French. The French taste for stylistic uniformity, which spread from the premier circles in Paris and Versailles throughout most of France and was popular 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
In 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, indicate that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping gives the information from which accounts are written but is a different process, prerequisite to accounting.

Fundamentally, bookkeeping records two types of information: (1) the current value, or equity, of the enterprise and (2) the changes in value—profit or loss—taking place in the business over a single time.

Management officials, investors, and credit grantors all require such information: management 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 outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to judge the financial statements of an entity in judging whether to grant a loan.

Evidence of financial and numerical record charts are seen for almost every group of people with a commercial backbone. Records of trading contracts were discovered in the archaelogy of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The double-entry style of bookkeeping came up with the development of the entrepeneurial republics of Italy, and manuals for bookkeeping were produced during the 15th century in some Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a paramount factor. The history of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, in part, assisted in forming it. The global expansion of industrial and commercial activity needed better sophisticate decision-making procedures, which itself called for higher sophistication in the selection, classification, and presentation of information, more so with the assistance of computers. Taxation and government legislature became more detailed and resulted in even greater need for information; firms had to provide information to list with 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 own departmental operations went up.

While bookkeeping procedures can be very complex, it is all based on two styles of books utilised in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so on), and the ledger has the details of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are constructed from the trial balance posted out of the ledger. The job of the income statement or profit-and-loss statement is to present an analysis of the changes that have taken place in the entity equity because of the events of the period. The balance sheet shows the financial situation of the enterprise at any particular point derived from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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.
