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

2010 July 19

The most typical question heard when purchasing a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many business brands and different types available, it can be overwhelming for customers to choose between the two technologies. The fact is that LCD projectors offer better image quality and colour accuracy. The following article will tell you why DLP projectors struggle with bringing up a comparable level of image quality.

Think of a set of blinds in your household for your bedroom window. By twisting a rod you can have the shutters open or closed, according to whether you want to let light in or not. And this is exactly how an LCD projector behaves. Each pixel operates like a unique shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element works 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 content reaches your screen is ultimately important to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 different LCD panels. The 3 LCD panels cast the elements of the image by shining each pixel on and off. The pixels are then projected in a glass prism to create the projector image. A significant point to realise about LCD projectors is that all three colours are projected onto your projected surface simultaneously. The way a DLP projector works is widely different and even the way an image appears is not the same. With DLP, white light from the lamp is processed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting an image casts a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to construct the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eye will then pull together each coloured element of the image into a single complete image. In LCD projectors, all colours are available all the time to offer top brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, and so causing lower colour brightness and accuracy. Some DLP developers have put a white segment into the colour wheel to improve overall brightness, but this goes and lessens colour accuracy.

I see in forums all the time that DLP provides a higher contrast ratio and thus must be superior quality. For those unaware, 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 have high contrast specifications in comparison to many LCD projectors. Initially, this can seem to be a plus, however, in real life, the true black level is determined by the ambient light in the room in which the projector is utilised. Do not be duped 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 marks, or ‘artifacts’. The most typical artifact that a DLP projector creates with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images keep changing between the time red, blue and green colours are displayed. LCD projectors do not have this disadvantage because all the colours are processed simultaneously. DLP developers have created 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them almost impossible for the majority of businesses and consumers.

Another variance between LCD and DLP is how they make up for the refractive qualities of light. Think back to high school science, and recall when they taught you how the various colours of light refract different amounts when projected through the same lens. The problem with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light at different levels. Usually with a DLP projector, a superfluous yellow colour will show above and a spill of blue will be projected below an image as simple as a single black line. While being built LCD projectors can be fixed to reduce these effects on the projected image, because each colour is directed on separate LCD panels.

The only true benefit (excluding price) with buying a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to portability and needs to be traded off against the image benefits of LCD projectors. If overall picture quality is crucial to you, then the decision is simple. Go for an LCD projector! LCD projectors will constantly show bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

2010 July 16

As the Dutch rose to preeminence in sea power during the 17th century, the early yacht was a leisure craft used first by royalty and then by the burghers for the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private matches. English yachting began 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) pleasure 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), 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 wager. Yachting was found to be popular for the rich and royalty, but after that period the fashion did not last.

The first yacht association in the British Isles, the Water Club, was instigated at about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, with large naval panoply and gravity. The closest thing to racing was the “chase,” when the “fleet” pursued a fictional enemy. The club endured, mostly as a social club, until 1765, and in 1828, by merging with other clubs, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated fashion on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been started 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 society at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for large stakes were held, and the society life was lovely. Eventually Royal Yachting Club boats were raised in size to over 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English had dominance. Sailing was for the most part for leisure and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a benchmark of luxury and sophistication for the later yachts in the area from the late 19th century. The first continuing American yacht club, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The design of sizeable yachts was first largely affected by the success 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.) had its namesake after its win at Cowes in 1851. Earlier yachts were not designed and crafted in today’s sense, with only a model used. Not until the later half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the application of the study of aerodynamics do for the structure of sails and rigging what science had previously done for hulls.

Because most of all sailboats had to be individually manufactured, there came a requirement for handicapping boats previous to the one-design class boats were built. Hence, a rating rule came into being, which ended up in the International Rule, accepted in 1906 and edited in 1919. Today, one of the rapidly blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are created to the same dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between those boats can be held on an even playing field with no handicapping required. A great example is the generic International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

As long as yachting was done mostly for the royal and the affluent, money was no issue, and the size of boats grew, in both length and weight. The rise and desire of smaller yachts occurred 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of less sizeable boats. Following this in the 20th century, for the larger part after World War II, smaller racing and leisure boats became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, during which steam was set to replace sail power in commercial boats, the steam engine, and later the internal-combustion engine, were increasingly favoured in pleasure vessels. Bigger power yachts were progressed to a high standard, and long-distance sailing became a favoured pastime of the rich. The early power yachts were paddle-wheel boats; these then gave rise to yachts powered by the wholly submerged screw or propeller type of propulsion. As in the case of naval and merchant boats, auxiliaries with both sail and power were the yacht standard for many years. By the second half of the 20th century, several 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. Conspicuous within these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed 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 saw active service in World War II.

As bigger and better quality internal-combustion engines were developed, many bigger boats began using them for power. The creation of the diesel engine, employing heavy oil for fuel, progressed in World War I. During the decade following, big power-yacht creation grew, climaxing in the Orion (1930) at 3,097 tons. From that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power craft declined after 1932, and the fashion from then was for smaller, less pricey boats. After World War II, lots of small naval craft were sold to private owners for conversion to yachts. At the late 20th century, yachting had become a widespread loved activity enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small pleasure boats. The amount of yachts and sailors has increased steadily, not only in the traditional places on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

2010 July 8

Taxes are differentiated by the effect they have on the distribution of income and wealth. A proportional tax is the kind of tax that places the same relative requirement on all taxpayers—i.e., in the case where tax liability and income move in equal levels. A progressive tax is recognisable by a larger than proportional rise in the tax burden relative to the growth in income, and a regressive tax is characterized by a less than proportional rise in the comparative onus. Therefore, progressive taxes are seen as reducing the lack of equality in income distribution, but regressive taxes are believed to result in an increase these inequalities.

The taxes that are usually regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, might become less so for the upper-income group—particularly if a taxpayer is able to lessen his tax base by nominating deductions or by taking some income parts from his taxable income. Proportional tax rates if applied to lower-income groups would also be more progressive if exemptions of a personal nature are declared.

Income measured over a given year might not absolutely come up with the best measure of taxpaying requirement. For example, transitory rises in income could be saved, and in temporary declines in income a taxpayer could choose to provide for consumption by reducing savings. Ergo, if taxation is compared along with “permanent income,” it can be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (except those on luxuries) tend to be regressive, because the share of own income consumed or spent on specific goods declines as the level of personal income grows. Poll taxes (also called head taxes), nominated as a flat amount per capita, patently are regressive.

It is hard to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effects of taxation, it is relevant to distinguish between several points of tax rates. The statutory rates will include those nominated in legislature; usually these are marginal rates, but in some cases they are average rates. Marginal income tax rates denote the fraction of incremental income that is taken by taxation when income increases by one dollar. Thus, if tax liability grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that increase as income increases. Structured analysis of marginal tax rates need to take into account provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than specified within the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the appropriate ones for regarding incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate to apply to income from business and capital, because it may rely on such factors 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 nothing under a consumption-based tax.

Average income tax rates indicate the fraction of total income that is required in taxation. The pattern of average rates is the one that is necessary 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 rise with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received for the most part by high-income households could dwarf these effects, allowing regressivity, as displayed by average tax rates that fall as income rises.

The Development of Data Projectors

2010 June 30
by squadron

The LCDs put in projection systems are most often small reflective or transmissive panels lit by a bright arc lamp source. A series of lenses enlarges 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, although in rear-projection systems the screen is lit up from behind. Projectors of higher expense and performance sometimes use three distinct LCD panels, creating separate red, green, and blue images that come together to create a coloured picture on the screen.

The increasing requirement for film presentations has granted a particular emphasis on the switching speed of liquid crystals. This has necessitated the invention of objects using smectic liquid crystals, particular types of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most sophisticated smectic device. In it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and throughout the layers the molecules are on a tilt, as demonstrated in the figure. The host liquid crystal has optically active molecules, and a subtle outcome of the optical activity and the angle of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Thus, there has to be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The consequential change in optical properties can create a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been commercialized for big passive-matrix presentations, but their cost and complexity has stopped them from having any particular progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their fast response allows them to be utilised in time-sequential colour systems, in which highly expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in quick pace (about 100 cycles in a second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods but to a nontransmissive state in the blue period, with the upshot 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 all the furniture pieces, the chair could be of most importance. While most of the other pieces (apart from the bed) are created to support objects, the chair supports the human form. The term chair was looked upon here in the larger sense, from stool to throne to complex items like a bench and sofa, which should be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly distinguished.

The social history of the chair is as stimulating as its history as art and craft. The chair is not simply a physical support and aesthetic creation; it can also be a symbol of social hierarchy. In the historical royal courts there were plain distinctions between being led to a chair with arms, sitting on a chair with a back but without arms, or having to make do with a stool. During the 20th century, the director’s and/or manager’s chair has risen an identifier of superior position, like in democratic government debate the speaker sits on a higher floor.

In its furniture purpose, the chair can be utilised for a variety of various forms. There are chairs manufactured to attend to man’s age and physical condition (the high chair, the wheelchair) and for his rank in society (the executive chair, the throne). During past times there were chairs used for birth (birth chairs); from the 20th century, there have been chairs for ending life (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our modern lifestyle has demanded unique chairs for automobiles and aircraft. Each and every one of these chair kinds have been changed to conform to different human desires. Due to its particular association with man, the chair appears to its full advantage only when used. Though it is irrelevant to one’s appreciation of a cupboard or a chest of drawers whether there are items inside or not, a chair is really understood and judged best by a person sitting on it, for chair and sitter complement the other. Thus the various limbs of the chair were named likened to the areas of the human body: arms, legs, feet, back, and seat.

Because the simple role of a chair is to support our body, its credit is evaluated principally from how well it does measure up to this practical use. In the creation of the chair, the carpenter is bound under the static rules and principal measurements. Inside these limitations, however, the chair maker has marvellous freedom.

The history of the chair lasted a period of several thousand years. There are societies that had made significant chair types, expressions of the foremost object in the areas of technique and creativity. In these societies, individual 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of expert design, are known from tomb discoveries. First of the two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair has four legs shaped similar to those of a particular animal, a curved seat, with a sloping back supported by vertical stretchers. From this design a solid triangular form was made. There was in our knowledge no significant variation from the structure of Egyptian thrones and chairs for ordinary non-royals. The main change was in the intricacy of its ornamentation, in the selection of pricier inlays. The Egyptian folding stool in all likelihood was manufactured to be an easily stored seat for officers. As a camp stool the kind stayed during much later points in time. But the stool then also was designed for the character of a ceremonial seat, its original job as a folding stool being forgotten. This can already be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the construction of folding stools but are not able to be folded because the seats are worked out of wood. The easy build of the folding stool, composed of two frames that cycle on metal bolts and support a seat of leather or fabric secured between them, came up but somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this kind is the folding stool, made out of ashwood, found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not with any ancient fossil still in form but as found in a large amount of pictorial items. The best recognised is the klismos drawn on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those are displayed. These odd legs were considered to be created in bent wood and were likely to have been needed to bear great pressure under the weight of the sitter. The joints holding the legs to the frame of the seat had to be therefore super solid and were plainly drawn.

The Romans emulated the Greek chair; a number of casts of seated Romans are examples of a thicker and which appear to be a slightly less delicately constructed klismos. Both kinds, the light or the heavy, were seen again during the Classicist period. The klismos influence is used in French Empire styles, in English Regency, and in particular forms of notable iconicism of Denmark and Sweden during 1800.

China
The ancestry of the chair in China cannot be tracked as far back as the history of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) a full collection of drawings and works of art had been preserved, showing the insides and outer parts of Chinese houses and their furniture. Also kept of the 16th century are some chairs constructed of wood or lacquered wood, that display an astonishing likeness to pictures of past chairs.

Just like in Egypt, there were two iconic chair designs in China: a chair with four legs and a folding stool. That four-legged chair was seen both with or without arms however always with a square seat and straight stiles (upright side supports) to firm the back. In one style, though, the stiles had been delicately curved on top of the arms in order to suit the angle of the S-shaped back splat (the main upright of a back). All three areas had been mortised onto the yoke-like top rail. While the design of the Chinese back splat later had an inspiration for English chairs during the Queen Anne period, wooden members that would only to a restricted limit stabilise corner joints (and furthermore were loose in the result) are a feature exclusive to Chinese chairs. The four legs are set through the seat frame, which stops about the rounded staves. All members are round in section or is given rounded edges—an acknowledgement maybe to the bamboo tradition. The seat is not comfortable and occasionally had a plaited bottom. These chairs required the sitter to be stiff and upright; for if too much weight is exerted on the back, the chair has a tendency to topple. In patriarchal Chinese households of this period armchairs most likely were kept for older persons, for they were esteemed greatly.

The Chinese folding stool is thought to have travelled to China from the West. It does not vary very much from the Egyptian and Scandinavian folding stools, but it has a difference in that the top rail is elegantly fixed to the two legs of the stool with a curved member, which is generally seen with metal mounts. From a Western understanding the resultant effect of both furniture items is stylized. The construction and aesthetic issues are combined in a manner that is simultaneously naïve and refined. The pieced-together appearance is a result of the manner that the individual members do not seem to have been fixed together by means of either glue or screws, but are mortised into one another and fixed in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Artworks display a design of chair with a relatively crude wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between, stitched to bring up a pattern of tiny pads. The front board and a related board at the back could be folded after loosening some tiny iron hooks. Thus the chair was an easily portable piece of furniture for traveling which, during the same time, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be evidenced in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair might also be found in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not held that the innovation actually began 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 made in considerable quantities, as indicated from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up by a wall. The style asserts itself with 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 style—that was, as created in Paris around 1750—disseminated over most of Europe and has been imitated or copied into the mid-20th century. The chair owes the popularity to a combination of comfort and charm. The seat adheres to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are strongly constructed on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of fairly thick measurements; but all the members are deeply molded, all extraneous wood has been removed, and more expensive examples might be further embellished with special delicate and decorative carving. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all the upholstery on the seat, back, and armrests; cane is sometimes used instead of upholstery.

English chairs of the 18th century were more open in form than the French. The French taste for stylistic uniformity, which came from the most distinguished circles in Paris and Versailles within most of France and was popularised in many 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 reknowned and was widely distributed throughout the world.

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

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

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

What is Bookkeeping?

2010 June 23
by squadron

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

Predominantly, bookkeeping grants two kinds of information: (1) the current value, or equity, of the enterprise and (2) changes in value—profit or loss—taking position in the entity over a singular time.

Management officials, investors, and credit grantors all demand this kind of information: management in order to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to understand the upshots of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to assess the financial statements of an entity in finding whether to allow a loan.

Pieces of financial and numerical charts have been uncovered for almost every society with a commercial history. Records of trade contracts have been discovered in the ruins of Babylon, and accounts for both farms and estates have been archived in ancient Greece and Rome. The double-entry style of bookkeeping started with the progression of the entrepeneurial republics of Italy, and tutorials for bookkeeping were developed in the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial recordkeeping a paramount factor. The ancestry of bookkeeping, in fact, reflects closely the ancestry of commerce, industry, and government and, in some part, helped in forming it. The global movement of industrial and commercial activity demanded higher sophisticated decision-making methodology, which itself demanded better sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government regulation became more detailed and resulted in greater need for information; business entities had to show available information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the requirement for bookkeeping for their own departmental operations increased.

Though bookkeeping methods can be very complex, it is all based on two styles of books employed in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so forth), and the ledger must have the details of individual accounts. The daily records from the journals are entered 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 in the ledger. The point of the income statement or profit-and-loss statement is to present an analysis of those changes that happen in the enterprise equity because of the transactions of the period. The balance sheet gives the financial condition of the company at any particular day with regard to assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

2010 June 9

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

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

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

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

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

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

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

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

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

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

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

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