Organic light-emitting diode

An organic light-emitting diode (OLED), also Light Emitting Polymer (LEP) and Organic Electro-Luminescence (OEL), is any light-emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. The layer usually contains a polymer substance that allows suitable organic compounds to be deposited. They are deposited in rows and columns onto a flat carrier by a simple "printing" process. The resulting matrix of pixels can emit light of different colors.

Neptune

Neptune (pronounced /'n?ptju? n/[8]) is the eighth and farthest planet from the Sun in the Solar System. It is the fourth largest planet by diameter, and the third major by mass. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus, which is 15 Earth masses and less dense. The planet is named following the Roman god of the sea. Its astronomical symbol is a stylized story of Poseidon's trident.

Discovered on September 23, 1846, Neptune was the first planet found by mathematical prediction quite than regular observation. Unexpected changes in the orbit of Uranus led astronomers to realize the gravitational perturbation of an unknown planet. Neptune was found within a degree of the predict position. The moon Triton was found shortly thereafter, but none of the planet's other 12 moons were discovered preceding to the twentieth century. Neptune has been visit by only one spacecraft, Voyager 2, which flew by the planet on August 25, 1989.

Mosasaurs

Mosasaurs (from Latin Mosa meaning the 'Meuse river' in the Netherlands, and Greek sauros meaning 'lizard') were serpentine marine reptiles. The first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse about 1780. These ferocious marine predators are now considered to be the closest relatives of snakes, due to cladistic analysis of symptomatic similarities in jaw and skull anatomies.Mosasaurs were not dinosaurs but lepidosaurs, reptiles with overlapping scales.

These predators evolved from semi-aquatic squamates known as the aigialosaurs, close relatives of modern-day monitor lizards, in the Early Cretaceous Period. During the last 20 million years of the Cretaceous Period (Turonian-Maastrichtian), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators.

Synthetic biology

The term synthetic biology has long been used to describe an approach to biology that attempts to integrate (or "synthesize") different areas of research in order to create a more holistic understanding of life. More recently the term has been used in a different way, signaling a new area of research that combines science and engineering in order to design and build ("synthesize") novel biological functions and systems. The present article discusses the term in this latter meaning.

Cybernetics

Cybernetics is the study of feedback and derived concepts such as communication and control in living organisms, machines and organisations. Its focus is how anything (digital, mechanical or biological) processes information, reacts to information, and changes or can be changed to better accomplish the first two tasks.

The terms "systems theory" and "cybernetics" have been widely used as synonyms. Some authors use the term cybernetic systems to denote a proper subset of the class of general systems, namely those systems that include feedback loops. However Gordon Pask's differences of eternal interacting actor loops (that produce finite products) makes general systems a proper subset of cybernetics. According to Jackson (2000), Bertalanffy promoted an embryonic form of general system theory (GST) as early as the 1920s and 1930s but it was not until the early 1950s it became more widely known in scientific circles.

Trotskyism

Trotskyism is the theory of Marxism as advocated by Leon Trotsky. Trotsky considered himself a Bolshevik-Leninist, arguing for the establishment of a vanguard party. He considered himself an advocate of orthodox Marxism. His politics differed sharply from those of Stalin or Mao, most importantly in declaring the need for an international "permanent revolution". Numerous groups around the world continue to describe themselves as Trotskyist and see themselves as standing in this tradition, although they have diverse interpretations of the conclusions to be drawn from this.

Trotsky advocated proletarian revolution as set out in his theory of "permanent revolution", and he argued that in countries where the bourgeois-democratic revolution had not triumphed already (in other words, in places that had not yet implemented a capitalist democracy, such as Russia before 1917), it was necessary that the proletariat make it permanent by carrying out the tasks of the social revolution (the "socialist" or "communist" revolution) at the same time, in an uninterrupted process.

Neuropsychology

Neuropsychology is an interdisciplinary branch of psychology and neuroscience that aims to understand how the structure and function of the brain relate to specific psychological processes and overt behaviors. The term neuropsychology has been applied to both lesion studies of humans and animals and efforts to record electrical activity from individual cells (or groups of cells) in higher primates.

It is scientific in its approach and shares an information processing view of the mind with cognitive psychology and cognitive science.

Clinical psychology

Clinical psychology includes the study and application of psychology for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development. Central to its practice are psychological assessment and psychotherapy, although clinical psychologists may also engage in research, teaching, consultation, forensic testimony, and program development and administration. Some clinical psychologists may focus on the clinical management of patients with brain injury—this area is known as clinical neuropsychology. In many countries clinical psychology is a regulated mental health profession.

Anti-realism

In philosophy, the term anti-realism is used to describe any position involving either the denial of an objective reality of entities of a certain type or the denial that verification-transcendent statements about a type of entity are either true or false. This latter construal is sometimes expressed by saying "there is no fact of the matter as to whether or not P." Thus, we may speak of anti-realism with respect to other minds, the past, the future, universals, mathematical entities (such as natural numbers), moral categories, the material world, or even thought. The two construals are clearly distinct and often confused.

KHR-1

The KHR-1 is a programmable, bipedal humanoid robot introduced in June 2004 by a Japanese company Kondo Kagaku. At the time of its introduction it was one of the least expensive programmable bipedal robots (prices averaging around $1,600 in the United States and ¥128,000 in Japan). The robot is 34cm high and has 17 degrees of freedom (each joint is powered by individual servomotor). It is capable of a wide range of motions, including quick kung-fu-style fighting moves.

The KHR-1 can be controlled via RF remote control and modified receiver; however, these units do not come with the robot and must be purchased separately. Other accessories/modifications include additional degrees of freedom (waist and leg motion), a high performance motion processor microcontroller capable of real-time master/slave operation, gyros and multi-axis accelerometers, larger foot/sole plates.

Wireless networks

A wireless network is basically the same as a LAN or a WAN but there are no wires between hosts and servers. The data is transferred over sets of radio transceivers. These types of networks are beneficial when it is too costly or inconvenient to run the necessary cables. For more information, see Wireless LAN and Wireless wide area network. The media access protocols for LANs come from the IEEE.

The most common IEEE 802.11 WLANs cover, depending on antennas, ranges from hundreds of meters to low kilometers. For larger areas, either communications satellites of various types, cellular radio, or wireless local loop (IEEE 802.16) all have advantages and disadvantages. Depending on the type of mobility needed, the relevant standards may come from the IETF or the ITU.

List of nanotechnology applications

Although there has been much hype about the potential applications of nanotechnology, most current commercialized applications are limited to the use of "first generation" passive nanomaterials. These include titanium dioxide nanoparticles in sunscreen, cosmetics and some food products; silver nanoparticles in food packaging, clothing, disinfectants and household appliances; zinc oxide nanoparticles in sunscreens and cosmetics, surface coatings, paints and outdoor furniture varnishes; and cerium oxide nanoparticles as a fuel catalyst. The Woodrow Wilson Center for International Scholars' Project on Emerging Nanotechnologies hosts an inventory of consumer products which now contain nanomaterials.

However further applications which require actual manipulation or arrangement of nanoscale components await further research. Though technologies currently branded with the term 'nano' are sometimes little related to and fall far short of the most ambitious and transformative technological goals of the sort in molecular manufacturing proposals, the term still connotes such ideas. Thus there may be a danger that a "nano bubble" will form, or is forming already, from the use of the term by scientists and entrepreneurs to garner funding, regardless of interest in the transformative possibilities of more ambitious and far-sighted work.

wireless LAN

A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. WLAN utilizes spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area, also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network.

For the home user, wireless has become popular due to ease of installation, and location freedom with the gaining popularity of laptops. Public businesses such as coffee shops or malls have begun to offer wireless access to their customers; some are even provided as a free service. Large wireless network projects are being put up in many major cities. Google is even providing a free service to Mountain View, California and has entered a bid to do the same for San Francisco. New York City has also begun a pilot program to cover all five boroughs of the city with wireless Internet access.

What is Dynamic compilation in Java?

Dynamic compilation is a method used by some programming language implementations to increase performance during program execution. The best-known language that makes use of this technique is Java. The dynamic compiling is originated in self. It permits optimizations to be made that can only be well-known at runtime. The Runtime environments by dynamic compilation characteristically have programs run slowly for the first few minutes, and then after that, nearly all of the compilation and recompilation is done and it runs fast. Because of this initial performance lag, dynamic compilation is undesirable in some cases. In most implementations of the dynamic compilation, few optimizations that could be done at the initial compile time are delayed until further compilation at runtime, causing additional unnecessary slowdowns. Just-in-time compilation is a type of dynamic compilation in java.

Destructor in C++

A destructor is a class associate function that has the same name as the constructor (and the class) but with a ~ (tilde) in front. It is declared as like this in a program
~Circle() ;
When an object goes out of extent or more rarely is explicitly destroyed, its destructor is called. For example if the object has dynamic variables, like pointers then that require to be freed and the destructor is the proper place. Unlike constructors, the destructors can and should be made virtual if you have derived classes.

The use of the destructor is to release or relinquish all resources for example memory, close any open files etc when an object of this class is destroyed. Normally such resources will have been acquired by the class constructor.

Supercar-Development of the regulations

The V8 Supercar is the most important motor racing series in Australia. A V8 Supercar is a five-liter V8 powered sedan, and the races are held in all states of Australia and New Zealand and also China.

To the disappointment of a greater part of fans who had watched a long history of Ford-Holden battles in Australian touring the car categories since 1960s, international touring car regulations seemed destined to stop the Australian-built Holden Commodore and Ford Falcon in the early 90s. But, this was avoided with V8 only regulations being drafted, in partnership the Ford and Holden, to showcase their big Australian made cars.

What do you mean by Training Effect?

The Training Effect is a physical phenomenon identified to athletes. When a person exercises at an assured level for certain duration more than a certain number of weeks, their body will lift up its metabolism to an upper level - it will maintain at this level as long as a certain amount of exercise is performed all couple of days. This outcome was discovered by Dr. Kenneth H. Cooper of United States Air Force in the late 1960s. Dr. Cooper coined the term "Training Effect".

The considered effects were that muscles of respiration were strengthened, the heart was strengthened, the blood pressure was sometimes lowered and the whole amount of blood and number of red blood cells rises, making the blood a more competent carrier of oxygen. The VO2 Max was raises.

The exercise essential can be accomplished by any aerobic exercise in an extensive variety of schedules - Dr. Cooper found it is the finest to award "points" for all amount of exercise and necessitate 30 points a week to keep the Training Effect.

Freeway and its Design features

A freeway (is also superhighway, expressway or motorway as further explained below) is a multi-lane public road or highway planned for high-speed travel by great numbers of vehicles, and having no traffic lights, stop signs, or other regulations requiring vehicles to stop for cross-traffic.

Freeways have high speed limits and multiple lanes for travel in every direction. The number of lanes may differ from four or six in rural areas to as high as sixteen or eighteen in definite global cities. Freeway entrances and exits are restricted in number, and are intended with special onramps and off ramps, so as to make sure that vehicles do not disrupt the most important flow of traffic as they enter or leave the freeway. In few countries, the exits are numbered. Exit numbering may perhaps be by mile or kilometer, or in a simple sequential fashion. Where freeways cross, engineers give interchanges with elaborate ramp systems that permit for smooth, uninterrupted transitions connecting all through routes (as funds permit).

For the reason that the high speeds lessen decision time, freeways generally have more traffic signs than the equivalent signs on most highways and roads; the signs are time and again also larger. In most important cities, mainly on freeways six lanes in width or wider, guide signs are mounted on overpasses or overhead gantries so that drivers can see where each lane goes. Another ordinary problem with freeways is that it is almost impossible to keep away from wrong-way drivers, and the subsequent head-on collisions are often fatal. For that reason, special signage and lane markings are used to discourage drivers from going the wrong way. Freeways do not generally have traffic lights, but expressways may, in places where this distinction is made.

A general view on Glasses

The Glasses, spectacles, or eyeglasses are frames manner lenses worn in front of the human eyes, sometimes for just aesthetic reasons but in general for vision correction or eye protection. The Special glasses are used for viewing the three-dimensional images or experiencing virtual reality.

The Modern glasses are typically supported by pads on the bridge of the nose and by temples placed over the ears. The Historical types consist of the pince nez, monocle, and lorgnette. The Glasses are more often called eyeglasses in North American English, rarely spectacles in British English, and (rarely) frames or lenses. The Spectacles are often shortened to specs. In hipster jargon they are cheaters.

The Glasses were initially made from glass, but many are now made from plastic (often polycarbonate) because of the danger of breakage and the greater weight of glass lenses. Some plastics also have more beneficial optical properties than glass, like better transmission of visible light and better absorption of ultraviolet light. Some plastics have a greater index of refraction than the majority types of glass, allowing thinner lenses for a given prescription. Scratch-resistant coatings can be applied to most plastic lenses charitable them similar scratch resistance to glass. Hydrophobic coatings intended to ease cleaning are also obtainable, as are anti-reflective coatings designed to improve night vision and make the wearer's eyes more visible.

The Corrective spectacles have lenses created to correct vision abnormalities, like myopia. The Safety glasses are a type of eye protection against flying debris or noticeable and near visible light or radiation. The Sunglasses care for against high levels of visible and ultraviolet light.

The real facts about Jupiter

Jupiter is the fifth planet from the Sun and by distant the largest. Jupiter is above twice as huge as all the additional planets combined. Jupiter is about 90% hydrogen and 10% helium (by numbers of atoms, 75/25% by mass) with traces of methane, water, ammonia and "rock". This is very near to the composition of the primordial Solar Nebula from which the full solar system was formed. Saturn has a related composition, but Uranus and Neptune have much fewer hydrogen and helium.

Jupiter is the fourth shinning object in the sky (after the Sun, the Moon and Venus). It has been recognized since prehistoric times as a bright "wandering star". However in 1610 when Galileo first pointed a telescope at the sky he revealed Jupiter’s four large moons Io, Europa, Ganymede and Callisto (currently known as the Galilean moons) and recorded their motions back and forth just about Jupiter. This was the first finding of a center of motion not it seems that centered on the Earth. It was a most important point in favor of Copernicus's heliocentric theory of the motions of the planets (along with other new facts from his telescope: the phases of Venus and the mountains on the Moon). Galileo's outspoken support of the Copernican theory got him in mess with the Inquisition. Today anyone can replicate Galileo's observations (without fear of retribution :-) using binoculars or a cheap telescope.

Jupiter and the added gas planets have high velocity winds which are confined in broad bands of latitude. The winds blow in reverse directions in adjacent bands. Slight chemical and temperature differences between these bands are in charge for the colored bands that govern the planet's appearance. The brightness colored bands are called zones; the dark ones belts. The bands have been identified for some time on Jupiter, but the complex vortices in the boundary regions between the bands were first seen by Voyager. The data from the Galileo probe specify that the winds are even faster than expected (more than 400 mph) and make bigger down into as far as the probe was able to view; they may extend down thousands of kilometers into the center. Jupiter's atmosphere was also found to be pretty turbulent. This indicates that Jupiter's winds are determined in large part by its internal heat fairly than from solar input as on Earth.
