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

The Big Crunch

The typical question asked when looking for a new projector for the home, office, or classroom is: would I get an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many different brands and models available, it can be confusing for clients to make a choice between those technologies. The simple fact of the matter is that LCD projectors give far better image quality and colour accuracy. The following article will explain why DLP projectors struggle with projecting a comparable grade of image quality.

It’s like a set of blinds in your room covering 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 that is exactly how an LCD projector operates. Each pixel operates like a unique shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as the professionals like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point when the projector switches on to when the picture reaches your screen is absolutely important in 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 project the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then projected in a glass prism to send the projector image. An important point to know about LCD projectors is that all three colours are directed onto your screen at once. The way a DLP projector functions is widely different and even the final product of 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 approach to making 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 form the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s vision will then put together each coloured element of the image into the full image. With LCD projectors, all colours are available all the time to form the top level of brightness and spectacular colour accuracy. In DLP, just one colour is available at a time, resulting in lower colour brightness and accuracy. Some developers have included a white segment in the colour wheel to improve general brightness, but this also detracts from colour accuracy.

I find in forums all the time that DLP provides a higher contrast ratio and therefore must be superior quality. For those who are 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 technology is capable of. DLP projectors do offer high contrast specifications as compared to most LCD projectors. At first glance, this must be a plus, however, in the real world, the true black level is determined by the ambient light in the room in which the projector is being utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you plan to see includes moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change between the time red, blue and green colours are projected. LCD projectors do not have this problem because the colours are processed with the others. DLP builders have developed 3DLP solutions using 3 chips to resolve the colour break up error, but the cost of these projectors make them impractical for the large part of businesses and consumers.

Another variance between LCD and DLP is how they make up for the refractive qualities of light. Jump back to high school science, and remember when they taught you how different colours of light refract different amounts when directed through the same lens. The disadvantage with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light differently. Often with a DLP projector, an extra yellow colour will come up above and a spill of blue will show below an image of something as simple as a lone black line. In building LCD projectors can be adjusted to take away these effects on the projected image, as each colour is directed on separate LCD panels.

The one veritable buy point (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant in regard to transporting the device and must be traded off against the image plusses of LCD projectors. If the result of the picture quality is crucial to you, then the decision is no-brainer. Take an LCD projector! LCD projectors will consistently make bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

The Big Crunch   
Digg it Add to del.icio.us Stumble it No Comment

As the Dutch came to preeminence in sea power during the 17th century, the first yacht was a pleasure craft used initially by royalty and then by the burghers in the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) 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, ruled 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 punt. Yachting became classy among 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 organization, and had much naval panoply and rigour. The closest thing to racing was the “chase,” in which the “fleet” pursued an imagined enemy. The club persisted, mostly as a social club, until 1765, and in 1828, when merging with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered method on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it came to be called 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 group 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 racing. The club at Cowes became the Royal Yachting Club, also at the accession of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing tests for large bets were held, and the society life was lovely. It came to be that the Royal Yachting Club boats grew 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 held power. Sailing was for the most part for fun and found 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 that area from the late 19th century. The first persisting American yacht group, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The craft of bigger yachts was initially greatly affected by the success of America, which was designed by George Steers for a association led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. Earlier yachts were not designed and manufactured in today’s sense, with just a model for an outline. Not until the latter half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the employment of the research of aerodynamics do for the structure of sails and rigging what science had previously done for hulls.

Because almost all sailboats had to be individually manufactured, there arose a need for handicapping boats as this was previous to the one-design class boats were made. Hence, a rating rule was decreed, which ended up in the International Rule, accepted in 1906 and revised in 1919. In the present day, one of the rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are created to single specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between these boats can be done on an even keel with no handicapping required. A perfect example is the uniform International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

So long as yachting was an activity mostly for the royal and the affluent, expense was no object, and the size of boats developed, in both length and weight. The rise and desire of smaller yachts came in the second half of the 19th century out of 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 value of smaller craft. Following this in the 20th century, for the larger part after World War II, smaller racing and leisure craft became more popular, 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
Following the decade 1840–50, during which steam started to take the place of sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly used in personal yachts. Large power yachts were developed to a high element, and long-distance sailing became a fond activity of the well off. The early power yachts were paddle-wheel boats; these then made way to yachts powered by the fully submerged screw or propeller sort of propulsion. As in the case of naval and merchant yachts, auxiliaries with both sail and power were the yacht archetype for many years. By the later half of the 20th century, many yachts were still auxiliaries, but the larger part were exclusively power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a push in the design of large 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 operated by a crew of at least 150. The Mayflower, bought 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 in World War II.

As larger and more dependable internal-combustion engines were developed, many big yachts started using them for power. The creation of the diesel engine, employing heavy oil for fuel, progressed in World War I. In the decade after that, bigger power-yacht manufacture flourished, climaxing in the Orion (1930) at 3,097 tons. From that time the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power boats lessened after 1932, and the trend thereafter was toward smaller, less pricey boats. Following World War II, many small naval boats were bought by private owners for conversion to yachts. By the late 20th century, yachting has become a globally beloved competition enjoyed by thousands of yachtsmen who are actually sailing and upkeeping their own small leisure boats. The number of craft and yachtsmen has increased steadily, not only in the traditional areas along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

The Big Crunch   
Digg it Add to del.icio.us Stumble it No Comment

Taxes are distinguished by the effect they have on the placement of income and wealth. A proportional tax is the kind of tax that applies the same relative burden on each taxpayer—i.e., when tax liability and income increase in equal scale. A progressive tax is characterizable by a higher than proportional growth in the tax liability in relation to the rise in income, and a regressive tax is characterized by a less than proportional increase in the comparable burden. So, progressive taxes are viewed as reducing inequalities in income distribution, while regressive taxes are believed to have the effect of an increase in these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, may become less so within the upper-income group—in particular if a taxpayer is able to lessen his tax base by declaring deductions or by taking particular income elements from his taxable income. Proportional tax rates if applied to lower-income groups could also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the course of a given period does not absolutely provide the most accurate measure of taxpaying ability. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer may decide to pay for consumption by taking from savings. Thus, if taxation is compared with “permanent income,” it would be less regressive (or more progressive) than if it is made comparable with annual income.

Sales taxes and excises (except luxuries) are generally regressive, because the portion of own income consumed or spent on a specific good declines as the amount of personal income grows. Poll taxes (also called head taxes), levied as a flat amount per capita, clearly are regressive.

It is not easy to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of the uncertainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden rests crucially on whether a national or a subnational (that is, provincial or state) tax is being determined.

In considering the economic effect of taxation, it is relevant to distinguish between several points of tax rates. The statutory rates are dictated in law; generally speaking these are marginal rates, but for some cases they are median rates. Marginal income tax rates note the fraction of incremental income that is taken by taxation when income increases by one dollar. Hence, if tax onus increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislature generally contain graduated marginal rates—i.e., rates that grow as income increases. Structured analysis of marginal tax rates should regard provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than specified in the statutory rates. Since marginal rates indicate 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 complicated to realise the marginal effective tax rate to apply to income from business and capital, since it may be dependant on considerations including 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 display the part of total income that is paid in taxation. The pattern of average rates is the one that is necessary for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally increase with income, both because personal allowances are permitted for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received predominantly by high-income households can dwarf these effects, forcing regressivity, as displayed by average tax rates that decrease as income rises.

The Development of Data Projectors

The Big Crunch

The LCDs used 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 the screen. For front-projection systems the LCD is located on the side of the screen as the viewer, however in rear-projection systems the screen is set off from behind. Projectors of more expense and capacity might use three distinct LCD panels, reflecting separate red, green, and blue images that combine to form a coloured display on the screen.

The growth in requirement for film presentations has put a particular emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items using smectic liquid crystals, certain ones of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most developed 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 throughout the layers the molecules are on a tilt, as shown in the figure. The host liquid crystal holds optically active molecules, and a slight consequence of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. Therefore, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly attracted 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 so reverse the tilt direction of the molecules. The respective change in optical properties can effect a change from light to dark when one or more polarizers are employed.

SSFLC devices have been publicized for big passive-matrix presentations, but their cost and detail has impeded them from making any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be employed in time-sequential colour systems, in which expensive colour filters are replaced with a coloured backlight that flashes red, green, and blue in rapid pulsing (approx 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods but then 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

The Big Crunch   
Digg it Add to del.icio.us Stumble it No Comment

Out of all furniture needs, the chair might be the imperative one. While the majority of other pieces (except the bed) are intended to support objects, the chair supports our human form. The term chair is viewed here in the wider sense, from stool to throne to developed chairs for example a bench or sofa, which may be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinguished.

The social history of the chair is as intriguing as its history as a creative art. The chair is not merely a physical support and an aesthetic piece; it historically was a symbol of social standing. From the past royal courts there were clear signifiers 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. From the recent century, the director’s and/or manager’s chair has developed a signifier of superior rank, and even in democratic government meeting the speaker sits on a higher level.

As a furniture form, the chair can be used for a range of different makes. There are chairs structured to suit man’s age and physical capabilities (the high chair, the wheelchair) and to indicate his rank in society (the executive chair, the throne). From past days there were chairs for births (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 can make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern day living has designated particular chairs in automobiles and aircraft. Every one of these chair shapes has been changed to conform to growing human uses. Because of its close relationship with man, the chair exists to its full significance only when in use. Although it is not relevant to one’s appreciation of a cupboard or a chest of drawers whether there are items inside or not, a chair is really seen best and evaluated by a person sitting in it, for chair and sitter suit one another. Thus the several elements of a chair were labeled like the parts of a human shape: arms, legs, feet, back, and seat.

Because the principal purpose of your chair is to support the body, its credit is tested firstly on how completely it fulfills this practical purpose. Within the creation of a chair, the maker is restricted for particular static legislation and principal measurements. In these rules, however, the chair creator has awesome freedom.

The history of the chair extended over a period of several thousand years. There are peoples that made distinctive chair types, expressions of the topmost task in the spheres of skill and creativity. Out of these such civilisations, particular note should 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 lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of skilled make, are seen from tomb findings. The first of them is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs designed like those of some animal, a curved seat, and leading to a sloping back supported over vertical stretchers. From this design a durable triangular structure was made. There was in our knowledge no notable differentiation between the structure of Egyptian thrones and chairs for common people. The general change exists in the level of ornamentation, in the particulars of expensive inlays. The Egyptian folding stool likely was developed as an easily stored seat for army officers. As a camp stool the type stayed for much later points in time. But the stool also was made for the character of a ceremonial seat, its original role as a folding stool fast forgotten. This can today be found, 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 in the construction of folding stools but can’t be folded because the seats are made of wood. The simplistic construction of the folding stool, composed of two frames that turn on metal bolts and hold a seat of leather or fabric held between them, then came again but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this kind is the folding stool, crafted out of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is seen not with any ancient object still in form but as seen from a large amount of pictorial material. The best known is the klismos placed on the Hegeso Stele at the Dipylon burial ground just out of Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs would be shown. These curving legs were probably executed in bent wood and were likely to have been put under a large amount of pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat are therefore very strong and were visibly indicated.

The Romans borrowed from the Greek design; existing models of seated Romans offer chairs of a more heavyset and which appear to be a rather more crudely designed klismos. Both features, the light or the heavy, were revived in the Classicist time. The klismos influence is known in French Empire furniture, in English Regency, and in special kinds of notable individuality in Denmark and Sweden circa 1800.

China
The ancestry of the chair in China can not be charted as far as the progression of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) a full folio of drawings and paintings had been preserved, detailing the interiors and outer parts of Chinese buildings and the designs of furniture. Also kept since the 16th century are some chairs constructed of wood or lacquered wood, that show an amazing familiarity to styles of older chairs.

Just the same as in Egypt, two major chair forms existed in China: a chair having four legs and a folding stool. This four-legged chair can be constructed both with or without arms but always having a square seat and straight stiles (upright side supports) to hold up the back. In one type, it has been seen, the stiles are marginally curved above the arms for the purpose of sit right with the structure of the S-shaped back splat (the centre upright of its chairback). The three parts were mortised into the yoke-like top rail. Despite that the idea of the back splat had a foundation for English chairs from the Queen Anne period, wooden sections that only to a particular capability reinforce corner joints (and then are loose in the bargain) signify a signature exclusive to Chinese chairs. The four legs are set through the seat frame, which stops around the rounded staves. Members are round in section or has rounded edges—a left over perhaps to the bamboo tradition. The seat is not pleasant and had on occasion a plaited form. These chairs demanded of the sitter to remain stiff and upright; for if too much pressure is pushed on the back, the chair has a way of falling over. In patriarchal Chinese houses of this era armchairs most likely were allowed only for senior persons, for they were held in great esteem.

The Chinese folding stool is understood to have travelled to China from the West. It does not vary very much from the Egyptian or Scandinavian folding stools, but it has a difference in that the top rail is delicately joined to the two legs of the stool by use of a curved member, which is generally provided with metal mounts. From a Western point of view the overall effect of both of these furniture forms is stylized. The structure and decoration parts are combined in a style that is all at once both naïve and refined. The patched up appearance is an upshot of the way that the individual members do not appear to have been affixed by means of either glue or screws, but had been mortised onto one another and held in position 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 project a design of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to show up a pattern of tiny pads. The front board and a similar board at the back could be folded after loosening some little iron hooks. Thus the chair was a portable piece of furniture when traveling which, in the same period, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is seen in engravings of the 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 kind of chair might also be seen in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the style actually was instigated in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slim measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was manufactured in impressive numbers, as can be surmised from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up against a wall. The form asserts itself by its shapely proportions and delicate 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 was, as brought out in Paris around 1750—spread through most of Europe and has been imitated or copied into the mid-20th century. The model owes its popularity to a combination of leisure and elegance. The seat conforms to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads on the armrests. Smooth transitions are made between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of relatively thick measurements; but every member is deeply molded, all extraneous wood has been taken away, and more expensive designs would be further embellished with special delicate and decorative engraving. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all upholstery on the seat, back, and armrests; cane is occasionally used rather than upholstery.

English chairs of the 18th century were more differentiated in design than the French. The French taste for stylistic uniformity, which came from the highest circles in Paris and Versailles over most of France and was popularised 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 popularised 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 styles 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?

The Big Crunch   
Digg it Add to del.icio.us Stumble it No Comment

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping provides the details from which accounts are written but is a different process, required prior to accounting.

Essentially, bookkeeping records two areas of information: (1) the current value, or equity, of the entity and (2) the changes in value—profit or loss—taking position in the enterprise from a particular period of time.

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

Bits and pieces of financial and numerical records are uncovered for nearly every civilization with a commercial background. Records of trade contracts have been found in the remains of Babylon, and accounts for both farms and estates were made in ancient Greece and Rome. The double-entry method of bookkeeping came up with the furthering of the entrepeneurial republics of Italy, and instruction books for bookkeeping were developed in the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made perfect financial records a requirement. The past of bookkeeping, in fact, resembles closely the history of commerce, industry, and government and, in part, assisted in shaping it. The global expansion of industrial and commercial activity demanded better cosmopolitan decision-making procedures, which in its turn required greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government regulation became more important and resulted in greater demand for information; entities 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 grew in size, and the demand for bookkeeping for their own departmental operations became larger.

While bookkeeping processes can be rather multifaceted, all of it is based on two types of books employed in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger has the information of individual accounts. The daily records in the journals are put in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are made from the trial balance posted from the ledger. The point of the income statement or profit-and-loss statement is to present an analysis of the changes that have occurred in the ownership equity as a result of the transactions of the period. The balance sheet displays the financial condition of the enterprise at a particular point regarding assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

The Big Crunch   
Digg it Add to del.icio.us Stumble it No Comment

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 trend 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.
