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

Posted: July 19th, 2010 | Author: squadron | Filed under: Uncategorized | Tags: , | No Comments »

The 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, 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 types available, it can be overwhelming for customers to choose between those technologies. It comes down to the fact that LCD projectors have better image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with creating a similar standard of image quality.

It’s like a set of blinds in your household covering your bedroom window. By a twist of a rod you can have the shutters open or closed, depending on if you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel functions like a single shutter on a set of blinds to either send light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from when the projector turns on to when the image reaches your screen is vitally 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 send the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by processing each pixel on and off. The pixels are then simultaneously processed in a glass prism to form the projector image. Something to understad about LCD projectors is that all three colours are directed onto your screen simultaneously. The way a DLP projector works is very different and even how an image shows up is not the same. With DLP, white light from the lamp is directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s eye will then draw each coloured element of the image into a total image. With LCD projectors, all colours are available all the time to offer the best brightness and great colour accuracy. In DLP, just one colour is available at a time, and so causing lower colour brightness and accuracy. Some manufacturers have added a white segment into the colour wheel to improve all over brightness, but this goes and detracts from colour accuracy.

I read in forums all the time that DLP provides a higher contrast ratio and as such must be superior. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is capable of producing. DLP projectors do have high contrast specifications as compared to a majority of LCD projectors. Initially, this can seem to be a benefit, however, in reality, the true black level is determined by the ambient light in the room where the projector is being utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to view needs moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most often seen artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this disadvantage because all the colours are sent at once. DLP designers have created 3DLP solutions using 3 chips to solve the colour break up issue, but the price tag of these projectors make them almost impossible for most businesses and consumers.

Another variance between LCD and DLP is how they make up for the refractive qualities of light. Take yourself back to high school science, and remember how various colours of light refract various amounts when passing through the same lens. The disadvantage with DLP projectors is that they utilise the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light in a different way. Often with a DLP projector, some extra yellow colour will appear above and some extra blue will come through below an image containing something as simple as a single black line. While being built LCD projectors can be adjusted to remove these effects on the projected image, as each colour is processed on its own LCD panels.

The only true plus (excluding price) with choosing a DLP projector is its smaller size and weight. However, this is only relevant with regard to transporting the device and must be traded off against the image superiority of LCD projectors. If the outcome of the picture quality is important to you, then the answer is no-brainer. Go with an LCD projector! LCD projectors will always create bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

Posted: July 16th, 2010 | Author: squadron | Filed under: Uncategorized | Tags: , | No Comments »

As the Dutch rose to dominance in sea power during the 17th century, the early yacht was a pleasure craft used first by royalty and later by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, coming out of private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English royalty in 1660, the city of Amsterdam presented him with 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, sovereign 1685–88), built more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting became popular among the affluent and royalty, but after that period the habit did not last.

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

Yacht racing began in some organized manner on the Thames in the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was known as 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 association had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yachting. The organisation at Cowes became the Royal Yachting Club, also at the ascension of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing matches for large bets were held, and the social life was lovely. Eventually Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and persisted when the English had dominance. Sailing was largely for leisure and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled 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 association, the Detroit Boat Club, was started 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 were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The design of sizeable yachts was originally greatly put upon by the success of America, which was drawn by George Steers for a club started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its success at Cowes in 1851. Early yachts were not designed and built in today’s sense, with just a model used. Not until the latter half of the 19th century did what was called naval architecture come about. Not until the 1920s did the use of the study of aerodynamics do for the structure of sails and rigging what science had already done for hulls.

Because most of all sailboats had been individually custom-built, there arose a need for handicapping boats as this was previous to the one-design class boats were designed. Hence, a rating rule was decreed, which is found in the International Rule, adopted in 1906 and amended in 1919. In modern times, one of the rapidly growing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to standard dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between those boats can be done on an even playing field with no handicapping required. A great example is the standard International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

As long as yachting was an activity primarily for the royal and the affluent, cost was no issue, and the size of boats grew, in both length and weight. The ascendancy and desire of smaller boats occurred 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 voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the value of less sizeable craft. Later in the 20th century, notably after World War II, smaller racing and leisure yachts became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, in which steam was set to emulate sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were used increasingly in personal boats. Bigger power yachts were furthered to a high element, and long-distance sailing became a preferred activity of the affluent. The earliest power yachts were paddle-wheel boats; they then gave rise to boats powered by the completely submerged screw or propeller sort of propulsion. Like naval and merchant yachts, auxiliaries with 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 larger part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the construction of bigger steam yachts. In particular 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, 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 during World War II.

As more sizeable and more dependable internal-combustion engines were created, many bigger yachts were using them for power. The creation of the diesel engine, using heavy oil for fuel, progressed during World War I. In the decade following that, bigger power-yacht building blossomed, climaxing in the Orion (1930) at 3,097 tons. In that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of larger power craft declined from 1932, and the fashion after that was toward smaller, less costly boats. After World War II, a lot of small naval craft were traded by private owners for conversion to yachts. At the late 20th century, yachting had become a widespread loved competition enjoyed by thousands of yachtsmen who are actually owning and maintaining their own small leisure yachts. The amount of yachts and yachtsmen increased steadily, not only in the traditional places by the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Posted: July 8th, 2010 | Author: squadron | Filed under: Uncategorized | Tags: , | No Comments »

Taxes can be differentiated by the effect they have on the placement of income and wealth. A proportional tax is one that impinges the same relative requirement on every taxpayer—i.e., where tax liability and income move in equal levels. A progressive tax is recognised by a higher than proportional rise in the tax burden in relation to the rise in income, and a regressive tax is characterized by a less than proportional rise in the comparable onus. So, progressive taxes are seen as reducing inequity in income distribution, whereas regressive taxes are found to have the result of increasing these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so in the upper-income categories—in particular if a taxpayer is permitted to lessen his tax base by claiming deductions or by leaving out some particular income elements from his taxable income. Proportional tax rates that are applied to lower-income classes can also be more progressive if personal exemptions are declared.

Income measured over the course of a given period may not absolutely come up with the most suitable measure of taxpaying status. For example, transitory growth in income could be saved, and during temporary declines in income a taxpayer could select to pay for consumption by taking from savings. Therefore, if taxation is held in comparison alongside “permanent income,” it would be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (with the exception of luxuries) are mostly regressive, because the spread of one’s income consumed or spent on a specific good declines as the level of personal income rises. Poll taxes (also known as head taxes), levied as a fixed amount per capita, patently are regressive.

It is not simple to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to a lack of certainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden is dependant essentially on whether a national or a subnational (that is, provincial or state) tax is being debated.

In analysing the economic purpose of taxation, it is important to distinguish between several points of tax rates. The statutory rates are those nominated in the law; often these are marginal rates, but sometimes 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. So, if tax onus increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax regulations generally contain graduated marginal rates—i.e., rates that grow as income rises. Careful analysis of marginal tax rates are required 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 growth in income, the marginal rate is 20 percentage points greater than indicated within the statutory rates. Since marginal rates specify how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for appraising incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applied to income from business and capital, because it may be reliant on such considerations 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 zero under a consumption-based tax.

Average income tax rates show the portion of total income that is taken in taxation. The pattern of average rates is the one that is relevant for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally grow with income, both because personal allowances are allowed 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 for the most part by high-income households can swamp these effects, producing regressivity, as indicated by average tax rates that lower as income increases.

The Development of Data Projectors

Posted: June 30th, 2010 | Author: squadron | Filed under: Uncategorized | No Comments »

The LCDs utilised in projection systems are usually small reflective or transmissive panels lit up by a bright arc lamp source. A number of lenses expands the reflected or transmitted image then displays it on a screen. For front-projection systems the LCD is set on the same side of the screen as the viewer, while in rear-projection systems the screen is lit up from behind. Projectors of more expense and capability might be found with three separate LCD panels, creating separate red, green, and blue images that mesh to reflect a coloured image on the screen.

The increasing desire for video displays has granted a particular emphasis on the switching speed of liquid crystals. This has led to the invention of devices using smectic liquid crystals, certain types of which give a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most sophisticated smectic device. Inside it the liquid crystal molecules are set out in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and throughout the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible result of the optical activity and the tilt 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 is a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The resultant change in optical properties can cause a change from light to dark if or when one or more polarizers are used.

SSFLC devices have been publicized for larger passive-matrix displays, but their high cost and complexity has stopped them from making any great 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 quick reacting allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast pulsing (about 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state for the red and green periods but then to a nontransmissive state in the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Posted: June 26th, 2010 | Author: squadron | Filed under: Uncategorized | Tags: , | No Comments »

From each of the furniture needs, the chair might be the paramount one. While most of the other objects (except the bed) are devised to support objects, the chair supports a human form. The term chair is intended to be regarded here in the largest sense, from stool to throne to complex forms for example the bench or sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinuishable.

The social history of the chair is as exciting as its history as an art and craft. The chair is not merely a physical support and aesthetic piece; it is historically symbolic of social place. Within the past royal courts there were social signifiers between having a chair with arms, sitting on a chair with a back but without arms, and having to sit on a stool. From the recent century, a director’s or manager’s chair has developed an indicator of superior standing, and even in democratic government meeting the speaker sits on an elevated floor.

In a furniture purpose, the chair can be utilised for a number of various makes. There are chairs structured to attend to man’s age and physical abilities (the high chair, the wheelchair) and to denote his rank in society (the executive chair, the throne). From historical days there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs to die in (the electric chair). There are chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has developed particular chairs for use in automobiles and aircraft. Each of these chair shapes has been adapted to match to growing human uses. Because of its particular relationship with man, the chair comes to its full meaning only when in use. Though it is irrelevant to one’s appreciation of a cupboard or a chest of drawers if there might be things inside or not, a chair is understood best and tested by a person utilising it, because chair and sitter require one another. Thus the several parts of the chair have been labeled likened to the areas of a human shape: arms, legs, feet, back, and seat.

Because the primary role of your chair is to support the body, its worth is judged firstly from how suitably it measures up to this practical function. Within the design of the chair, the carpenter is bound under the static rules and principal measurements. Within these limits, however, the chair maker has great freedom.

The history of the chair lasted over a period of several thousand years. There were peoples that created individual chair shapes, as expressive of the premier object in the industries of technique and aesthetics. In such peoples, 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 structures of skilled design, are now found from tomb discoveries. The first of these is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have four legs structured as akin to those of a designated animal, a curved seat, and with a sloping back supported over vertical stretchers. From this design a solid triangular structure was obtained. There was to our knowledge no particular difference between the structure of Egyptian thrones and chairs for typical people. The simple variation exists in the intricacy of its ornamentation, in the selection of more valuable inlays. The Egyptian folding stool in all probability was made for an easily carried seat for army officers. As a camp stool that stool continued for much later points in time. But the stool then was created for the task of a ceremonial seat, its original history as a folding stool simply forgotten. This can today be observed, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the form of folding stools but cannot be folded as the seats were formed with wood. The easy manufacture of the folding stool, being of two frames that rotate on metal bolts and bear a seat of leather or fabric fastened between them, reappeared but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this type is the folding stool, made out of ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not from any ancient fossil still extant but from a wealth of pictorial items. The iconic kind is the klismos posited on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs would be displayed. These curving legs were presumed to have been manufactured out of bent wood and were in that case bore extreme pressure from the weight of the sitter. The joints joining the legs to the frame of the seat were therefore super stable and were visibly denoted.

The Romans borrowed from the Greek designs; designs of statues of seated Romans are designs of a heavier and are a somewhat less delicately designed klismos. Both types, the light or heavy, were seen again as part of the Classicist period. The klismos design can be evidenced in French Empire styles, in English Regency, and in special types of profound iconicism of Denmark and Sweden around 1800.

China
The ancestry of the chair in China cannot be charted as far back as the history of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) an undamaged folio of images and artworks had been kept, with images of the insides and outside of Chinese buildings and the kinds of furniture. Also kept from the 16th century are a trove of chairs constructed of wood or lacquered wood, that show an amazing resemblance to representations of ancient chairs.

As was the case in Egypt, there existed two fundamental chair designs in China: a chair with four legs and a folding stool. This chair was constructed both with and without arms although always having the square seat and straight stiles (standing side supports) to give support to the back. In one kind, it has been seen, the stiles are delicately curved above the arms so as to sit correctly with the angle of the S-shaped back splat (the centre upright of the back). The three limbs had been mortised onto the yoke-like top rail. Though the design of the Chinese back splat later had an inspiration for English chairs from the Queen Anne period, wooden items that would only to a limited extent stabilise corner joints (and were loose as a result) represent a signature solely to Chinese chairs. The four legs sit through the seat frame, which ends around the rounded staves. Every member is round in section or possesses rounded edges—referable perhaps to the bamboo tradition. The seat is not pleasant and had on occasion a plaited form. These chairs required the sitter to stay stiff and upright; when too much pressure is pushed on the back, the chair has a tendency to topple over. In patriarchal Chinese homes of this period armchairs likely were kept for elderly people, for they were esteemed greatly.

The Chinese folding stool is presumed to have taken to China from the West. It does not vary much from the Egyptian or Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is prettily held to the two legs of the stool by a curved member, which is more often than not possessing metal mounts. From a Western understanding the resulting effect of both of these furniture forms is stylized. The constructive and aesthetic elements are combined in a style that is all at once both naïve and refined. The piecemeal appearance is a result of the fact that the individual items do not appear to have been fixed together by means of either glue or screws, but have been mortised on one another and held in its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also put its name on the chair. Paintings project a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in the layers, stitched to produce a pattern of little pads. The front board and a related board at the back could be folded after loosening some small iron hooks. In this way the chair was a readily portable piece of furniture in traveling which, in the same era, granted the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be displayed in engravings of the interior of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this style of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not believed that the form actually began in The Netherlands. Normally, the legs of the chair are smooth, round in section, and of thin measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was made in vast amounts, as can be surmised from one of Abraham Bosse’s engravings, in which there is a row of such chairs lined up against a wall. The design asserts itself by its harmonious proportions and delicate upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that is, as progressed in Paris around 1750—spread over most of Europe and was imitated or copied in the mid-20th century. The style owes the popularity to a combination of comfort and elegance. The seat suits to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back cover all the joints, which are constructed solidly on craftsmanlike methods 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 members are deeply molded, all extraneous wood has been cut away, and finer items can be further embellished with special delicate and decorative woodwork. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for all of the upholstery on the seat, back, and armrests; canework is occasionally used instead of upholstery.

English chairs from the 18th century were more variable in design than the French. The French touch for stylistic uniformity, which came from the highest circles in Paris and Versailles over most of France and found favour in several 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
During the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

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

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

What is Bookkeeping?

Posted: June 23rd, 2010 | Author: squadron | Filed under: Uncategorized | No Comments »

Bookkeeping is the charting of the money values of the transactions of a business. Bookkeeping provides the numbers from which accounts are drafted but is a different process, preliminary to accounting.

Essentially, bookkeeping records two parts of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking position in the enterprise over a given time.

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

Pieces of financial and numerical charts have been found for just about every civilization with a commercial backbone. Records of commercial contracts were uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The dual-entry process of bookkeeping started with the progression of the enterprising republics of Italy, and tutorials for bookkeeping were created within the 15th century in various Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial recordkeeping a paramount factor. The history of bookkeeping, in fact, closely reflects the past of commerce, industry, and government and, in some part, helped in forming it. The international market of industrial and commercial activity required greater professional decision-making methodology, which itself needed greater sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government legislature became more important and resulted in greater need for information; business entities had to show information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the requirement for bookkeeping for their own inner operations became higher.

Though bookkeeping methods can be extremely detailed, all are based on two kinds of books employed in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger has the information of individual accounts. The daily records in the journals are put in the ledgers.

Each month, as a general rule, an income statement and a balance sheet are created from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to display an analysis of any changes that have taken place in the business equity because of the transactions of the period. The balance sheet shows the financial condition of the corporation at the particular day derived from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

Posted: June 9th, 2010 | Author: squadron | Filed under: Uncategorized | Tags: , , | No Comments »

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 yielded 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. 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.
