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

19 July, 2010 (13:35) | Uncategorized | By: The Captain

The typical question customers ask when purchasing a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and types available, it can be overwhelming for clients to choose between those technologies. It comes down to the fact that LCD projectors offer better image quality and colour accuracy. The article below tells you why DLP projectors struggle with reproducing a similar rate of image quality.

It’s like a set of blinds in your house for your bedroom window. With the twist of a rod you can turn the shutters open or closed, depending on if you want to let light in or not. And this is exactly how an LCD projector functions. Each pixel operates like a unique shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as professionals like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point when the projector turns on to when the image reaches your screen is ultimately important for image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by cutting it into red, blue and green components, by three mirrors which direct the coloured light to 3 separate LCD panels. The 3 LCD panels create the elements of the image by shining each pixel on and off. The pixels are then simultaneously processed in a glass prism to form the projector image. Something important to remember about LCD projectors is that all three colours are directed onto your projected surface at once. The way a DLP projector functions is very different and even the final product of how an image comes out is not the same. With DLP, white light from the lamp is projected 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 requires 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 displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into the total image. With LCD projectors, all colours are available all the time to deliver the top level of brightness and great colour accuracy. In DLP, just one colour is available at once, resulting in lower colour brightness and accuracy. Some manufacturers have put a white segment in the colour wheel to improve brightness overall, but this then degrades colour accuracy.

I find in forums all the time that DLP gives a higher contrast ratio and ergo must be better. For those unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is able to produce. DLP projectors do provide high contrast specifications when compared to many LCD projectors. At first glance, this must be an advantage, however, in truth, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you are trying to view includes moving images, DLP projection technology also creates image errors, or ‘artifacts’. The most commonplace artifact that a DLP projector creates with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change between the time red, blue and green colours are shone. LCD projectors do not have this problem because all colours are sent with the others. DLP manufacturers have created 3DLP solutions using 3 chips to fix the colour break up issue, but the cost of these projectors make them not practical for many businesses and consumers.

Another difference between LCD and DLP is how they make up for the refractive qualities of light. Think back to high school science, and recall how different colours of light refract varied amounts when shone through the same lens. The disadvantage with DLP projectors is that they take the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light in different ways. Usually with a DLP projector, some yellow colour will show above and a superfluous blue will come through below an image as simple as a straight black line. During manufacturing LCD projectors can be set to minimize these effects on the projected image, because each colour is refracted on its own LCD panels.

The only actual buy point (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant with regard to mobility and cannot be traded off against the image superiority of LCD projectors. If resulting picture quality is crucial to you, then the decision is simple. Choose an LCD projector! LCD projectors will always make bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

16 July, 2010 (07:59) | Uncategorized | By: The Captain

As the Dutch came to dominance in sea power during the 17th century, the first yacht had been a pleasure craft used mostly by royalty and secondly by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting was found to be classy with the wealthy and nobility, but after that point the trend did not last.

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

Yacht racing began in some stipulated manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to sovereignty in 1820, it was named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht club 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 perpetual location of British racing. The association at Cowes became the Royal Yachting Club, again at the accession of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing tests for high bids were held, and the club life was superlative. Eventually Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English held dominance. Sailing was mostly for pleasure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while aboard 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 until the later half of the 19th century. The craft of sizeable yachts was first greatly put upon by the victory of America, which was drawn by George Steers for a syndicate headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its victory at Cowes in 1851. Early yachts were not designed and crafted in today’s sense, with only a model being used. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the use of the science of aerodynamics do for the design of sails and rigging what science had earlier done for hulls.

Because almost all sailboats had to be individually custom-built, there was a need for handicapping boats as this was before the one-design class boats were designed. Therefore, a rating rule was written, which ended up in the International Rule, taken on in 1906 and edited in 1919. In the present day, one of the fastest flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to single requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even basis with no handicapping necessary. A great example is the generic International America’s Cup Class taken on board for participants in the 1992 America’s Cup race.

For the time that yachting was an activity mostly for the royal and the rich, expense was no object, and the size of boats developed, in both length and weight. The promotion and preference of smaller craft came in the latter half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of less sizeable boats. Following this in the 20th century, particularly after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, during which steam began to emulate sail power in commercial boats, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure boats. Sizeable power yachts were developed to a high standard, and long-distance sailing was a favoured pastime of the affluent. The early power yachts were paddle-wheel boats; these then made way to boats powered by the fully submerged screw or propeller sort of propulsion. Like naval and merchant boats, auxiliaries carrying both sail and power were the yacht archetype for several years. By the latter half of the 20th century, many yachts were still auxiliaries, but the majority were only power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a boom in the construction of more sizeable steam yachts. Conspicuous of 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 over 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service for World War II.

As bigger and better quality internal-combustion engines were produced, many big boats were using them for power. The development of the diesel engine, with heavy oil for fuel, advanced from World War I. From the decade after, large power-yacht manufacture blossomed, hitting a climax in the Orion (1930) at 3,097 tons. In that point the largest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power yachts fell away from 1932, and the style after that was for smaller, less expensive craft. Following World War II, many small naval boats were traded by private owners for conversion to yachts. In the late 20th century, yachting is a internationally loved competition enjoyed by thousands of yachtsmen personally owning and maintaining their own small recreational boats. The popularity of yachts and owners has increased steadily, not only in the traditional places along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

8 July, 2010 (05:55) | Uncategorized | By: The Captain

Taxes are categorized by the impact they have on the distribution of income and wealth. A proportional tax is a kind that puts the same relative requirement on all taxpayers—i.e., in the case where tax liability and income increase in the same proportion. A progressive tax is characterizable by a larger than proportional increase in the tax liability relative to the rise in income, and a regressive tax is characterizable by a less than proportional growth in the comparative onus. Therefore, progressive taxes are regarded as reducing inequalities in income distribution, whereas regressive taxes can cause an increase in these inequalities.

The taxes that are normally thought to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so within the upper-income demographic—especially if a taxpayer is permitted to lower his tax base by claiming deductions or by removing certain income aspects from his taxable income. Proportional tax rates that are applied to lower-income groups will also be more progressive if such exemptions of a personal nature are declared.

Income measured over the course of a given period might not absolutely offer the best measure of taxpaying ability. For example, transitory growth in income can be saved, and during temporary declines in income a taxpayer might decide to finance consumption by taking from savings. So, if taxation is compared along with “permanent income,” it would be less regressive (or more progressive) than if made comparable with annual income.

Sales taxes and excises (except luxuries) are usually regressive, because the spread of individual income consumed or spent for specific goods lessens as the level of personal income increases. Poll taxes (also known as head taxes), levied as a flat amount per capita, obviously are regressive.

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

In analysing the economic purpose of taxation, it is relevant to distinguish between several ideas of tax rates. The statutory rates are nominated in the legislation; generally these are marginal rates, but sometimes they are average rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income rises by one dollar. Ergo, if tax liability rises by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that increase as income grows. Careful analysis of marginal tax rates need to consider provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than nominated by the statutory rates. Since marginal rates signify how after-tax income changes in response to changes in before-tax income, they are the necessary ones for regarding incentive effects of taxation. It is even more complicated to know the marginal effective tax rate to apply to income from business and capital, since it may be reliant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates indicate the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly grow with income, both because personal allowances are allowed for the taxpayer and dependents and also because marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households could dwarf these effects, allowing regressivity, as signified by average tax rates that lower as income rises.

The Development of Data Projectors

30 June, 2010 (12:04) | Uncategorized | By: The Captain

The LCDs used in projection systems are generally small reflective or transmissive panels illuminated by a forceful arc lamp source. A series of lenses enlarges the reflected or transmitted image and then sends it on a screen. For front-projection systems the LCD is situated on the same area of the screen as the viewer, but in rear-projection systems the screen is set off from behind. Projectors of greater expense and capacity might have three discrete LCD panels, casting separate red, green, and blue images that come together to reflect a coloured display on the screen.

The increasing desire for visual displays has granted a growing emphasis on the switching speed of liquid crystals. This has demanded the invention of objects build with smectic liquid crystals, certain kinds of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. In it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and throughout the layers the molecules are on a slant, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a slight result of the optical activity and the angle of the molecules is the appearance 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 in the plane of the layers. Hence, there must be a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The respective change in optical properties can cause a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been publicized for larger passive-matrix displays, but their cost and intricacy has stopped them from enjoying any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some promise for use as parts in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be made use of 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 speed (around 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state for the red and green periods then to a nontransmissive state in the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

26 June, 2010 (12:32) | Uncategorized | By: The Captain

Out of each of the furniture objects, the chair could be the imperative one. While most other items (save for the bed) are meant to support objects, the chair supports our human form. The term chair was used here in the general sense, from stool to throne to further kinds including the bench or sofa, which can be looked upon 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 curious as its history as art and craft. The chair is not simply a physical support and/or aesthetic piece of art; it historically is a symbol of social status. Within the past royal courts there were important differences between being seated on a chair with arms, on a chair with a back but no arms, and having to utilise a stool. In the 20th century, the director’s and/or manager’s chair has been regarded as an indicator of superior dignity, and even in democratic government meeting the speaker sits on a raised level.

As its furniture purpose, the chair can be used for a variety of different models. There are chairs manufactured to fit man’s age and physical condition (the high chair, the wheelchair) and to denote his position in society (the executive chair, the throne). In past days there were chairs for births (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). We have chairs with one, two, three, and 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.

Modern living has designated unique chairs in automobiles and aircraft. Each and every one of these chair types have been changed to match to differing human desires. Because of its particular relationship with man, the chair exists to its full meaning only when being utilised. Although it isn’t relevant to one’s appreciation of a cupboard or a set of drawers if there are items inside or not, a chair is really seen best and regarded best with a person sitting on it, because chair and sitter require one another. Thus the various elements of a chair were named as the parts of our human parts: arms, legs, feet, back, and seat.

Because the fundamental work of a chair is to support the body, its credit is valued principally by how fully it does measure up to this practical use. In the construction of a chair, the maker is limited by particular static regulations and principal measurements. Through these limitations, however, the chair designer has extensive freedom.

The history of the chair lasted over a period of several thousand years. There were peoples that held significant chair types, seen of the premier work in the spheres of skill and design. Out of those cultures, particular 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the structures of skilled scheme, are now a finding from tomb discoveries. One of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair had four legs designed as akin to those of an animal, a curved seat, and with a sloping back supported by vertical stretchers. From this a solid triangular design was crafted. There appeared to be no notable variation in the creation of Egyptian thrones and chairs for common populace. The real difference lies in the level of ornamentation, in the particulars of pricey inlays. The Egyptian folding stool in all likelihood was developed to be an easily packed seat for army. As a camp stool this type persisted for much later days. But the stool also then was designed for the purpose of a ceremonial seat, its technical role as a folding stool neglected or forgotten. This can now be noted, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the form of folding stools but can’t be folded as the seats are formed of wood. The easy structure of the folding stool, made of two frames that cycle on metal bolts and support a seat of leather or fabric secured between them, is seen some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this kind is the folding stool, made from ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is recognised not from any ancient specimen still existing but from a wealth of pictorial objects. The iconic kind is the klismos placed on the Hegeso Stele at the Dipylon burial area by Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of them are visible. These creative legs were probably executed in bent wood and were in that case had great pressure under the weight of the sitter. The joints securing the legs to the frame of the seat would have had to be therefore very solid and were visibly indicated.

The Romans borrowed from the Greek style; a number of casts of seated Romans display examples of a heavier and in appearance somewhat less intricately constructed klismos. Both styles, the light or the heavy, were brought back during the Classicist period. The klismos chair is seen in French Empire chairs, in English Regency, and in particular forms of profound individuality around Denmark and Sweden during 1800.

China
The history of the chair in China is not able to be followed as well as the ancestry of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed collection of drawings and artworks has been preserved, with images of the interiors and outside of Chinese buildings and the kinds of furniture. Kept also of the 16th century are a collection of chairs crafted from wood or lacquered wood, that possess an astonishing similarity to representations of previous chairs.

As in Egypt, there was two major chair designs in China: a chair having four legs and a folding stool. This four-legged chair is designed both with and without arms although always having the square seat and straight stiles (upright side supports) to firm the back. In one kind, though, the stiles were delicately curved on top of the arms to conform correctly to the shape of the S-shaped back splat (the basic upright of a chairback). Together, all three limbs were mortised into the yoke-like top rail. Though the innovation of the Chinese back splat later had a foundation for English chairs within the Queen Anne period, wooden sections that could merely to a particular limit support corner joints (and furthermore are loose to top that off) indicate a design particular to Chinese chairs. The four legs are set through the seat frame, which ends over the rounded staves. Every member is round in section or has rounded edges—references perchance to the bamboo tradition. The seat is unpleasant to sit in and may have a plaited form. These chairs required of the sitter to hold themselves stiff and upright; for if too much weight is forced on the back, the chair has a tendency to topple over. In patriarchal Chinese houses of this epoch armchairs probably were kept only for older persons, for they were greatly respected.

The Chinese folding stool is presumed to have taken to China from the West. It is not dissimilar much from the Egyptian and Scandinavian folding stools, but it possesses a variation in that the top rail is elegantly joined to the two legs of the stool in a curved member, which is more often than not provided with metal mounts. From a Western perspective the resultant effect of both these furniture designs is stylized. The constructive and decorative issues are combined in a way that is all at once both naïve and refined. The patched up appearance is an outcome of the manner that the individual members do not seem to have been joined together by means of either glue or screws, but were mortised with one another and locked into place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also left its mark on the chair. Artworks project a type of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing between, stitched to produce a pattern of tiny pads. The front board and a similar board at the back could be folded after loosening some little iron hooks. In this way the chair was a portable piece of furniture for traveling which, in the same time, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be found in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this type of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not determined that the form actually started 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 unquestionably a bourgeois piece of furniture and was crafted in considerable amounts, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up against a wall. The style asserts itself by its elegant proportions and expensive 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 forms—that was, to say, as developed in Paris around 1750—spread through most of Europe and has been imitated or copied in the mid-20th century. The model owes the popularity to a combination of relaxation and charm. The seat suits to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike principles despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of rather thick measurements; but all the members are deeply molded, all extra wood has been taken away, and more upmarket examples would be further embellished with intricately delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for all upholstery on the seat, back, and armrests; cane is in some cases used instead of upholstery.

English chairs from the 18th century were more differentiated in style than the French. The French touch for stylistic uniformity, which came from the royal circles in Paris and Versailles over most of France and became the preference in large parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became 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 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?

23 June, 2010 (13:46) | Uncategorized | By: The Captain

Bookkeeping is the recordkeeping of the money values of the operation of a business. Bookkeeping gives the details from which accounts are prepared but is a different process, preliminary to accounting.

Fundamentally, bookkeeping finds two areas of information: (1) the current value, or equity, of a business and (2) any changes in value—profit or loss—taking place in the business from a single period.

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

Traces of financial and numerical recordkeeping can be uncovered for nearly every society with a commercial backbone. Records of trade contracts were found in the archaelogical digs of Babylon, and accounts for both farms and estates were made in ancient Greece and Rome. The two-entry process of bookkeeping started with the furthering of the enterprising republics of Italy, and tutorial manuals for bookkeeping were produced in the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a paramount factor. The past of bookkeeping, in fact, reflects closely the history of commerce, industry, and government and, in some part, assisted in forming it. The worldwide revolution of industrial and commercial activity called for greater professional decision-making methods, which in turn required more sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government regulation became more detailed and resulted in greater need for information; business entities had to have information available to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the need for bookkeeping for their inner operations increased.

While bookkeeping methodology can be very multifaceted, all of it is based on two kinds of books employed in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger contains the information of individual accounts. The daily records in the journals are entered in the ledgers.

Each month, by general practice, an income statement and a balance sheet are created from the trial balance posted out of the ledger. The point of the income statement or profit-and-loss statement is to provide an analysis of any changes that have taken place in the ownership equity from the events of the period. The balance sheet provides the financial condition of the business at a particular day in terms of assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

9 June, 2010 (06:31) | Uncategorized | By: The Captain

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 resulted in 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. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
