Top 10 Linux Distributions

2010-09-03T05:31:00.001-07:00

1. Ubuntu
Ubuntu is based on Debian and includes well-known applications such as Firefox and OpenOffice.org. It has a conventional, six-month free schedule, with infrequent Long Term Support (LTS) versions that are supported with safety updates for three to five years.

2. Fedora
Fedora is the free version of Red Hat, whose RHEL (Red Hat Enterprise Linux) has been a profitable product since 2003. Because of that close connection, Fedora is mainly strong on venture features, and it often offers them before RHEL does.

3. Linux Mint
Linux Mint is an Ubuntu-based distro that was just launched in 2006. The operating system adds to Ubuntu with its own, distinct desktop theme and a different set of applications; also unique to the distro are a variety of graphical tools for improved usability, such as mintDesktop for configuring the desktop environment, mintInstall for easier software installation and mintMenu for easier navigation.

4. OpenSUSE
openSUSE holds the No. 4 spot in popularity on the site and is also the base for Novell's SUSE Linux Enterprise Desktop and SUSE Linux Enterprise Server products.

The package's administration utility, YaST, is widely recognized as one of the best, and its boxed edition comes with some of the best printed documentation you'll find for any distro. I'd say openSUSE rates a "medium" on difficulty level.

5. PCLinuxOS
PCLinuxOS uses the KDE desktop environment and is basically a lighter-weight version of Mandriva. With good support for graphics drivers, browser plugins and media codecs, PCLinuxOS can be a good choice for beginners

6. Debian
Debian is currently known as one of the most well-tested and bug-free distros obtainable today. Though it serves as the foundation for Ubuntu, most view Debian as a distro best-suited for those knowledgeable with Linux

7. Mandriva
Mandriva is notable for its cutting-edge software, excellent administration suite and 64-bit edition. It was also the first major distribution to jump on the netbook bandwagon with out-of-the box support.

8. Sabayon/Gentoo
Italian Sabayon is essentially a LiveCD version of Gentoo, which is known for allowing users to individually optimize each component. Both are considered advanced Linux distributions aimed primarily at experienced users.

9. Arch Linux... plus Slackware

Arch is another package aimed primarily at experienced users interested in tweaking and optimizing their systems. Though not in the top 10 currently, Slackware is similarly oriented toward Linux gurus.

10. Puppy Linux... plus DSL
Puppy Linux, a compact distro that's ideal for older hardware and situations where computing resources are minimal.

Springbrook conservation plan

2009-02-25T23:31:00.000-08:00

A comprehensive conservation management plan designed to help protect and preserve the Springbrook Region Conservation Reserves into the future was today endorsed by Council’s Sustainable City Future Committee.

Committee Chair Cr Peter Young said the Springbrook Region Conservation Reserves Management Plan had been developed to protect the area’s biodiversity and unique cultural heritage.

“The management plan covers a large range of priorities for the area, such as native plant and animal conservation, bushfire management, ecological restoration and recreational opportunities for residents and visitors,” said Cr Young.

“The area is one of our city’s best natural areas and is truly a unique part of the Gold Coast.”

Divisional Councillor Ted Shepherd said it was very important to have in place a comprehensive strategic management plan that will regulate and protect the region’s significant natural value.

“Under the plan, Council’s key strategic priorities for the Springbrook Region Conservation Reserves also includes informing the community about protecting their environment and its wildlife, as well as community awareness and education campaigns on the importance of bushfire prevention and management,” said Cr Shepherd.

“The conservation plan is also supported by a detailed bushfire strategy for Springbrook developed in partnership by Council, the EPA and the Queensland Fire and Rescue service and this strategy is due to go before Council in the next six weeks.

“Community feedback on the draft plan was extensive, with a number of detailed submissions received.

“I believe we have the balance right between protecting the area’s conservation values and the ever growing demands of visitors.”

Space Shuttle

2009-01-22T05:12:00.000-08:00

NASA's Space Shuttle, officially called Space Transportation System (STS), is the United States government's present manned launch vehicle. At launch, it consists of a rust-colored outer tank, two white, slender solid rocket boosters (SRBs), and a winged orbiter. The orbiter carries astronauts and payload such as satellites or space location parts into low earth orbit. Normally, five to seven astronauts ride in the orbiter, with two pilots, eight have been carried, and eleven could be accommodated in an urgent situation landing. When the orbiter's work is complete, it fires its orbital maneuvering thrusters to drop out of orbit and re-enters the Earth's atmosphere. During the descent and landing, the shuttle orbiter acts as a glider and makes a completely unpowered landing. Five spaceworthy orbiters were build, of which three remain.

The Shuttle is the first orbital spacecraft considered for partial reusability. It carries large payloads to various orbits, provides crew rotary motion for the International Space Station (ISS), and performs servicing missions. The orbiter can also recover satellites and other payloads from orbit and return them to Earth, but this capability has not been used often. However, it has been used to return large payloads from the ISS to Earth, as the Russian Soyuz spacecraft has limited capacity for return payloads. Each Shuttle was designed for a expected lifespan of 100 launches or 10 years' operational life.

Pantechnicon & Pantech

2008-12-11T04:57:00.001-08:00

Pantechnicon is a old British expression for a furniture removal van. It was originally coined in 1830 as the name of a craft shop or bazaar, in Motcomb Street in Belgravia, London; the first name is Greek for pertaining to all the arts or crafts. The shop soon closed down and the building was twisted into a furniture warehouse, but the name was kept. Vehicles transporting furniture to and from the building, is called as pantechnicon vans, soon came to be known just for as pantechnicons.

A pantech truck or van is a word origin of "pantechnicon" usually currently used in Australia. A pantech is a truck and or van with a cargo hull made of (or converted to) hard panels.

Gear

2008-10-10T01:50:00.001-07:00

A gear is a wheel with teeth around its circumference, the purpose of the teeth being to mesh with similar teeth on another mechanical device possibly another gear wheel so that force can be transmitted between the two strategies in a direction tangential to their surfaces. A non-toothed wheel can transmit some tangential force but will slip if the force is large; teeth put off slippage and permit the transmission of large forces.

A gear can mesh with any device having teeth friendly with the gear's teeth. Such devices include racks and other non-rotating policy; however, the most common condition is for a gear to be in mesh with another gear. In this case revolution of one of the gears necessarily causes the other gear to rotate. In this way, rotational motion can be transferred from one position to another. While gears are sometimes used simply for this reason to transmit rotation to another shaft perhaps their most significant feature is that, if the gears are of asymmetrical sizes, a mechanical advantage is also achieved, so that the rotational speed, and torque, of the second gear are dissimilar from that of the first. In this way, gears provide a means of increasing or decreasing a turning speed, or a torque.

University

2008-07-09T10:43:00.000-07:00

A university is an institution of higher education and research, which grants intellectual degrees at all, levels in a selection of subjects. A university provides together tertiary and quaternary education. The word university is resultant from the Latin universities magistrorum ET scholarium, roughly importance community of teachers and scholars. The funding and organization of universities is very different in different countries around the world. In some countries universities are primarily funded by the state, while in others funding may come from donors or from fees which students’ presence the university must pay. In some countries the vast majority of students attends university in their local town, while in other countries universities attract students from all over the world, and may provide university space for their students.

The Carnegie Basic Classification system distinguishes between institutions on the basis of the prevalence of degrees they grant. As the names of their categories designate names indicate, the Carnegie Foundation considers the granting of master's degrees necessary, though not sufficient, for an institution to be classified as a university.

Animals

2008-05-14T10:45:00.000-07:00

Animals are a major group of generally motile, multicultural organisms that feed by consuming material from other living things. Their body plan becomes fixed as they develop, usually early on in their development as embryos, although some undergo a process of metamorphosis later on.

The word "animal" comes from the Latin word animal, of which animal is the plural, and is derived from anima, meaning vital breath or soul. In everyday colloquial usage, the word usually refers to non-human animals. The biological definition of the word refers to all members of the Kingdom Animalia. Therefore, when the word animal is used in a biological context, humans are included.

Rice

2008-03-14T06:05:00.000-07:00

Domesticated rice Poaceae ("true grass") family, Oryza sativa and Oryza glaberrima. These plants are native to humid and subtropical southern Asia and southeastern Africa. Rice provides more than one fifth of the calories consumed global by humans.(The term "wild rice" can refer to the wild species of Oryza, but predictably refers to species of the related genus Zizania, both wild and domesticated.) Rice is grown as a monocarpic annual plant, although in tropical areas it can endure as a perpetual and can produce a ratoon crop. Rice can grow to 1–1.8 m tall, intermittently more depending on the variety and soil fecundity. The grass has long, slender leaves 50–100 cm long and 2–2.5 cm broad. The small wind-pollinated flowers are shaped in a branched arching to pendulous inflorescence 30–50 cm long. The seed is a particle (caryopsis) 5–12 mm long and 2–3 mm thick.

Rice is a fasten for a large part of the world's human populace, especially in East, South and Southeast Asia, making it the most consumed cereal grain. Rice cultivation is well-suited to countries and regions with low labour costs and high precipitation, as it is very labour-intensive to develop and requires plenty of water for cultivation.

Rice can be grown virtually anywhere, even on steep hillsides. Although its species are native to South Asia and certain parts of Africa, centuries of trade and exportation have made it humdrum in many cultures.

The conventional method for cultivating rice is flooding the fields with or after setting the young seedlings. This simple method requires sound planning and servicing of the water damming and channeling, but reduces the growth of lesser strong tidy and pest plants and reduces vermin that has no submerged growth state. However, with rice growing and agriculture the flooding is not mandatory, whereas all other methods of irrigation require higher effort in weed and pest control during growth periods and a different draw near for fertilizing the mud.

Tiger

2008-03-12T07:27:00.000-07:00

The tiger (Panthera tigris) is a creature of the Felidae family, the largest of four "big cats" in the Panthera genus. Native to much of eastern and southern Asia, the tiger is an apex marauder and an necessitate carnivore. Reaching up to 4 metres (13 feet) in total length and weighing up to 300 kg (660 pounds), tigers are equivalent in size to the biggest vanished felids. Aside from their great bulk and power, their most recognizable feature is the pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts.

Highly adjustable, tigers range from the Siberian taiga to open grasslands to tropical mangrove swamps. They are defensive and generally solitary animals, often requiring large adjacent areas of habitat that support their prey demands. This, coupled with the fact that they are prevalent to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are destroyed and the remaining are classified as endangered, some critically so. The primary direct causes are habitat destruction and disintegration and hunting. Their historical range, which once reached from Mesopotamia and the Caucasus through most of South and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats.

Nonetheless, tigers are among most decipherable and popular of the world's charismatic megafauna. They have featured outstandingly in ancient mythology and folklore, and continue to be depicted in modern films and literature. Tigers appear on many flags, coats of arms and as mascots for sporting teams and serve as the national animal of several Asian nations.

River

2008-02-29T04:11:00.001-08:00

The water in a river is usually restrained to a channel, made up of a stream bed between banks. In larger rivers there is also a wider flood-plain shaped by flood-waters over-topping the feed. Flood plains may be very wide in relative to the size of the river channel. This dissimilarity between river channel and flood-plain can be blurred especially in urban areas where the flood-plain of a river channel can become greatly developed by housing and industry.

The river channel itself typically contains a single stream of water but some rivers flow as several interconnecting streams of water, producing a braided river. All-embracing braided rivers are found in only a few regions worldwide, such as the South Island of New Zealand. They also occur on peneplains and some of the larger river deltas. Anastamosing rivers are similar to braided rivers. They have multiple graceful channels carrying large volumes of sediment. Due to the dynamics of this type of system, they are also quite rare.

A river flowing in its channel is a source of energy which acts on the river channel to change its shape and form. In steep torrential zones this can be seen as erosion channels through hard rocks and the creation of sands and gravels from the devastation of larger rocks. In U shaped glaciated valleys, the consequent river valley can often easily be identified by the V shaped channel that it has carved. In the middle reaches where the river may flow over flatter land, loops (meanders) may form through eroding of the river banks and declaration on the inside of bends. Sometimes the river will cut off a loop, shortening the channel and forming an oxbow lake or billabong. Rivers that carry large amounts of deposit may develop conspicuous deltas at their mouths, if conditions permit. Rivers, whose mouths are in brackish tidal waters, may form estuaries. River mouths may also be fjords or rias.

Poetry

2008-02-12T04:10:00.001-08:00

Poetry is a form of art in which language is used for its artistic and reminiscent qualities in addition to, or in lieu of, its seeming meaning. Poetry may be written independently, as distinct poems, or may occur in concurrence with other arts, as in poetic drama, hymns or lyrics.

Poetry, and discussions of it, have a long history. Early attempts to define poetry, such as Aristotle's Poetics, focused on the uses of speech in rhetoric, drama, song and comedy. Later attempts concentrated on features such as reiteration and rhyme, and emphasised the aesthetics which discriminate poetry from text. From the mid-20th century, poetry has sometimes been more loosely defined as a fundamental creative act using language.

Poetry often uses particular forms and conventions to swell the accurate meaning of the words, or to evoke emotional or sensual responses. Devices such as assonance, alliteration, onomatopoeia and rhythm are sometimes used to achieve musical or incantatory effects. Poetry's use of uncertainty, symbolism, irony and other stylistic elements of poetic diction often leaves a poem open to multiple interpretations. Similarly, metaphor and simile create a significance between otherwise disparate images—a layering of meanings, forming connections previously not perceived. Kindred forms of resonance may exist, between individual verses, in their patterns of rhyme or rhythm.

Some forms of poetry are specific to particular cultures and genres, responding to the characteristics of the language in which the poet writes. While readers accustomed to identifying poetry with Dante, Goethe, Mickiewicz and Rumi may think of it as being written in rhyming lines and regular meter, there are traditions, such as those of Du Fu and Beowulf, that use other approaches to achieve rhythm and euphony. In today's globalized world, poets often borrow styles, techniques and forms from different cultures and languages.

Sound

2008-01-31T08:23:00.000-08:00

Sound is what can be professed by a living organism through its sense of hearing. Physically, sound is vibrational reflex energy that propagates through matter as a wave.

For humans, hearing is limited to frequencies between about 20 Hz and 20000 Hz, with the upper limit generally decreasing with age. Other species may have a different range of hearing. As a signal perceived by one of the major senses, sound is used by many species for detecting danger, navigation, predation, and statement. In Earth's atmosphere, water, and soil practically any physical phenomenon, such as fire, rain, wind, surf, or earthquake, produces (and is characterized by) its unique sounds. Many species, such as frogs, birds, marine and worldly mammals, have also developed special organs to produce sound. In some species these became highly evolved to fabricate song and (in humans) speech. Furthermore, humans have developed culture and technology (such as music, telephony and radio) that allows them to generate, record, transmit, and broadcast sounds.

The mechanical vibrations that can be interpreted as sound can travel during all forms of matter: gases, liquids, solids, and plasmas. However, sound cannot circulate through space. The matter that supports the sound is called the medium. Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called density waves. Through solids, however, it can be transmitted as both longitudinal and oblique waves. Sound is further characterized by the generic properties of waves, which are frequency, wavelength, period, amplitude, intensity, speed, and direction (sometimes speed and direction are combined as a velocity vector, or wavelength and direction are combined as a wave vector). Transverse waves, also known as shear waves, have an additional property of divergence. Sound characteristics can depend on the type of sound waves (longitudinal versus transverse) as well as on the physical properties of the transmission medium.

Cattle

2008-01-10T09:03:00.000-08:00

Cattle, colloquially referred to as cows, are disciplined ungulates, a member of the subfamily Bovina of the family Bovidae. They are raised as livestock for meat dairy products (milk), leather and as draught animals. In some countries, such as India, they are honored in religious ceremonies and revered. It is expected that there are 1.4 billion head of cattle in the world today.

Cattle were originally known by Carolus Linnaeus as three separate species. These were Bos taurus, the European cattle, including similar types from Africa and Asia, Bos indicus, the zebu,and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to together zebu and European cattle. More newly these three have increasingly been grouped as one species, sometimes using the names Bos primigenius taurus, Bos primigenius indicus and Bos primigenius. Complicating the matter is the capacity of cattle to interbreed with other closely related species. Hybrid individuals and even breeds exist, not only between European cattle and zebu but also with yaks, banteng, gaur, and bison, a cross-genera fusion. Cattle cannot effectively be bred with water buffalo or African buffalo.

Hardware

2007-12-14T07:13:00.001-08:00

Hardware is a general term that refers to the physical artifacts of a technology. It may also mean the physical components of a computer system.

Hardware historically meant the metal parts and fittings that were used to make wooden products stronger, more functional, longer lasting and easier to fabricate or assemble. In modern usage it includes equipment such as keys, locks, hinges, latches, corners, handles, wire, chains, plumbing supplies, tools, utensils, cutlery and machine parts, especially when they are made of metal. In the United States, this type of hardware has been traditionally sold in hardware stores, a term also used to a lesser extent in the UK.

In the electronics and especially computer industries, computer hardware specifically means the physical or tangible parts of the equipment, such as circuit boards, keyboards, monitors etc., in contrast to non-physical software running on the computer or other device.

In a more colloquial sense, hardware can refer to major items of military equipment, such as tanks, aircraft or ships.

Clothing

2007-11-28T04:56:00.000-08:00

Clothing protects the vulnerable nude human body from the extremes of weather, other features of our situation, and for safety reasons. Every article of clothing also carries a enriching and social meaning. Human beings are the only creatures known to wear clothing, with the exemption of pets clothed by their owners. People also decorate their bodies with makeup or foundation, perfume, and other ornamentation; they also cut, dye, and organize the hair of their heads, faces, and bodies, and sometimes also mark their skin. All these streamers contribute to the overall effect and message of clothing, but do not constitute clothing per se.

Articles carried rather than worn are normally counted as fashion garnishing rather than as clothing. Jewelry and eyeglasses are usually counted as accessories as well, even though in general speech these items are described as being worn rather than carried. The practical function of clothing is to protect the human body from dangers in the surroundings: weather, insects, noxious chemicals, weapons, and get in touch with with abrasive substances, and other hazards. Clothing can protect against many things that might injure the naked human body. In some cases clothing protects the environment from the clothing wearer as fine.

Humans have shown intense inventiveness in devising clothing solutions to practical problems and the difference between clothing and other protective equipment is not always clear-cut. See, among others: air inured clothing, armor, diving suit, swimsuit, bee-keeper's uniform, motorcycle leathers, high-visibility garments, and protective clothing.

Sea

2007-11-20T06:29:00.001-08:00

A sea is a great expanse of saline water associated with an ocean, or a large, generally saline, lake that lacks a natural opening such as the Caspian Sea and the Dead Sea. The term is used colloquially as identical with ocean, as in "the tropical sea" or "down to the sea shore", or even "sea water" to refer to water of the ocean. Large lakes, such as the Great Lakes, are at times referred to as inland seas. Many seas are marginal seas, in which currents are caused by ocean winds; others are Mediterranean seas, in which currents are caused by differences in salinity and temperature.

Trailer

2007-10-29T08:15:00.000-07:00

A Trailer is normally an unpowered vehicle pulled by a powered vehicle, because powered trailers are more explicitly called pot railers. Commonly, the term trailer refers to such vehicles used for transport of goods and materials. Trailer winches are intended to load (or unload) boats and other cargo to and from a trailer. The are invented a ratchet mechanism and cable. The handle on the ratchet mechanism is twisted to tighten or loosen the tension on the winch cable. There are both manual and motorized trailer winches

Popup campers are trivial, aerodynamic trailers that can be towed by a small car, such as the BMW Air Camper and the Coleman Bayside. They are built to be shorter than the tow vehicle, minimizing drag. Others range from two-axle campers that can be pulled by most mid-sized pickups to trailers that are as long as the host country's law allows for drivers without individual permits. Larger campers tend to be fully integrated leisure vehicles, which often are used to tow single-axle dolly trailers to allow the driver to bring small cars on their travels.

Rainbow

2007-10-19T03:06:00.000-07:00

Rainbows can be practical whenever there are water drop in the air and sunlight shining from behind the observer at a low altitude or angle. The most spectacular rainbow displays when half of the sky is still dim with draining clouds and the observer is at a spot with clear sky overhead. The rainbow effect is also commonly seen near waterfalls or fountains. Rainbow fringes can sometimes be seen at the edges of backlit clouds and as vertical bands in far rain or virga. The effect can also be artificially created by dispersing water droplets into the air during a sunny day. Rarely, a moonbow, lunar rainbow or night-time rainbow, can be seen on stoutly moonlit nights. As human visual observation for colour is poor in low light, moonbows are most often perceived to be white.
The rainbow's exterior is caused by dispersion of sunlight as it goes through raindrops. The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and over refracted as it leaves the drop. The overall effect is that the incoming light is reflected back over a wide range of angles, with the most intense light at an angle of 40°–42°. The angle is self-determining of the size of the drop, but does depend on its refractive index. Seawater has a higher refractive index than rain water, so the radius of a 'rain'bow in sea spray is smaller than a true rainbow. This is visible to the naked eye by a misalignment of these bows.

Reverberation

2007-10-10T09:29:00.000-07:00

When active sonar is used, spreading occur from small objects in the sea as well as from the bottom and surface. This can be a main source of interfering but does not occur with passive sonar. This scattering cause is different from that in room reverberation which is a reflection incident. An analogy for reverberation is the diffusion of a car's headlights in fog or mist. A high-intensity pencil beam will break in the fog; main headlights are less directional and where the returned noise dominates. Similarly, to overcome reverberation, an active sonar requests to transmit in a narrow beam.

Capacitance

2007-09-24T07:18:00.001-07:00

Capacitance is a measure of the quantity of electric charge stored for a given electric potential. The most general form of charge storage device is a two-plate capacitor. If the charges on the plates are +Q and -Q, and V gives the voltage difference between the plates, then the capacitance is given by c=Q/v. The capacitance of the majority of capacitors used in electronic circuits is several orders of size smaller than the farad. The most ordinary units of capacitance in use today are the millifarad (mF), microfarad (µF), the nanofarad (nF) and the picofarad (pF).
The dielectric constant for a number of very useful dielectrics changes as a function of the applied electrical field, e.g. ferroelectric materials, so the capacitance for these devices is no longer purely a purpose of device geometry. If a capacitor is driven with a sinusoidal voltage, the dielectric constant, or more exactly referred to as the dielectric permittivity, is a function of frequency. A changing dielectric constant with frequency is referred to as a dielectric dispersion, and is governed by dielectric recreation processes, such as Debye relaxation.

River

2007-09-05T09:07:00.001-07:00

A river is a natural waterway that transits water through a setting from higher to lower elevations. A river may have its basis in a spring, lake, from damp, boggy landscapes where the soil is waterlogged, from glacial melt, or from surface runoff of precipitation. Almost each and every one river is joined by other rivers and streams termed tributaries the highest of which are known as headwaters. Water may also begin from groundwater sources. Throughout the course of the river, the total volume transported downstream will often be a combination of the free water flow together with a important contribution flowing through sub-surface rocks and gravels that underlie the river and its floodplain. For many rivers in large valleys, this unseen component of flow may greatly go above the visible flow.
From their source, all rivers flow downhill, typically terminating in the sea or in a lake, through a confluence. In arid areas rivers sometimes end by losing water to desertion. River water may also infiltrate into the soil or pervious rock, where it becomes groundwater. Excessive abstraction of water for use in commerce, irrigation, etc., can also cause a river to dry before success its natural terminus.

Monitor

2007-08-29T03:42:00.000-07:00

A computer is a display device. A computer programming utility used for examining and modifying memory-resident engine code programs. The computer programming interface for synchronising concurrent access to a set of variables in a computer program. A hardware device that events electrical events such as pulses or voltage levels in a digital computer. A speaker used on stage to allow musicians to hear each other. Also called fold back a video monitor, a television-like device used in studio, lab or analysis environments. A supervisory control system for installations such as SCADA to monitor significant system parameters. Special installations require adapted monitoring installations like transformer monitors or substation monitors. A Hall monitor, one who patrols the entry of a school. A Prefect, schoolboy or schoolgirl given individual authority in some British schools, especially public schools.

Solar wind

2007-08-17T09:31:00.001-07:00

The solar wind is a stream of charged particles which are expelled from the upper atmosphere of the sun. It consists mostly of high-energy electrons and protons that are able to get away the sun's gravity in part because of the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time.

They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

Computation

2007-08-08T10:13:00.000-07:00

Computation is a common term for any type of information processing that can be represent mathematically. This includes phenomenon ranging from simple calculations to human idea. In a more narrow meaning, computation is a process following a well distinct model that is understood and can be expressed in an algorithm, protocol, network topology, etc.
These hypothetical computing equipment can be viewed as idealised analog computers which operate on real numbers and are differential, whereas digital computers are partial to computable numbers and are algebraic. Depending on the model select, this may enable real computers to solve problems that are inextricable on digital computers.

Power

2007-07-27T02:54:00.001-07:00

Power is the rate at which work is performed or energy is transmitted or the amount of energy essential or finished for a given unit of time. It is many types of conversion Power.Power (physics) is the quantity of work done or energy transferred per unit of time. Motive power is power which moves great, such as output of a motor. Electric power generation is the process of converting any form of energy to electrical energy.

Power station, a capability for generating electricity, nuclear power, the conversion of nuclear force to electricity, solar power, the translation of solar energy to electricity, wind power, the conversion of wind energy to electricity, wave power, the conversion of signal energy to electricity, tidal power, the conversion of energy of the tides energy to electricity, geothermal power, the conversion of geothermal power to electricity, hydropower, the conversion of possible or kinetic energy of water to electricity, Optical power of a lens is the opposite of its focal length, Effective radiated power in radio telecommunications is a calculate of radio station antennas

Reactance

2007-07-23T02:48:00.000-07:00

Reactance is the invented part of electrical impedance, a measure of opposition to a sinusoidal alternating current. Reactance arises from the occurrence of inductance and capacitance within a circuit, and the SI unit is the ohm. The value of the reactance is a lower maximum value on the amount of the impedance. A positive reactance implies that the phase of the voltage leads the phase of the current, while a harmful reactance implies that the phase of the voltage lags the phase of the current. A reactance of zero implies the current and voltage are in phase and equally if the reactance is non-zero then there is a phase distinction between the voltage and current

Energy meter

2007-07-17T04:46:00.000-07:00

An electric meter or energy meter is a machine that measures the amount of electrical energy supplied to a residence or business. These are customers of an electric company.

The most common type is more accurately known as a (kilo) watt-hour meter or a joule meter. They may also record other variables including the time, when the electricity was used. Modern electricity meters operate by continuously measuring the instantaneous voltage and current (amperes) and finding the product of these to give direct electrical power (watts) which is then integrated against time to give energy used (joules, kilowatt-hours etc). The meters fall into two essential categories, electromechanical and electronic. The type of meter described commonly used on a single-phase AC supply. Different phase of meter configurations use additional voltage and current coils. The most general type of electricity meter is the electromechanical induction meter.

Escalator

2007-07-11T05:30:00.001-07:00

An escalator is a conveyor transport device for transporting people, consisting of a staircase whose steps move up or down on tracks that keep the surfaces of the individual ladder horizontal. As a power-driven, continuous moving stairway planned to transport passengers up and down short vertical distances, escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage include shopping centers, airports, transit systems, convention centers, hotels, and public buildings.

They have the capacity to move large numbers of people, and they can be placed in the same physical space as set of steps. They have no waiting interval, except during very heavy traffic, they can be used to guide people towards main exits and they may be weather-proofed for outdoor use.

Computer

A computer is a machine for manipulating data according to a list of instructions.Computers take plentiful physical forms. Early electronic computers were the size of a large room, overriding as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to distinguish personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as a computer. However, the most general form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to organize other devices—for example; they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.
The ability to store and implement programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this flexibility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capability are not considerations.

Honey

Honey is a sweet and thick fluid produced by honey bees from the nectar of flowers. According to the United States National Honey Board and various international food system, honey stipulates a pure product that does not allow for the addition of any other substance...this includes, but is not limited to, water or other sweeteners. This article refers exclusively to the honey produced by honey bees honey twisted by other bees or other insect have very different properties. Honey is significantly sweeter than table sugar and has attractive chemical properties for baking. Honey has a typical flavor which leads some people to prefer it over sugar and other sweeteners.

Most microorganisms do not grow in honey because of its low water movement of 0.6[2]. However, it is important to note that honey frequently contains dormant end spores of the bacteria Clostridium outline, which can be perilous to infants as the end spores can transform into toxin-producing bacteria in the infant's immature intestinal tract, leading to disease and even death. The study of pollens and spores in raw honey can determine floral sources of honey. Because bees carry an electrostatic charge, and can attract other particles, the same techniques of melissopalynology can be used in area ecological studies of radioactive particles, sand, or particulate pollution.

Blocks

In computing, block size indicates a nominal size, usually expressed in bytes or bits, of a mass of data. Data thus controlled is said to be blocked. The process of putting data into blocks is called blocking. Blocking is used to assist the handling of the data-stream by the computer program receiving the data. Blocked data is generally read a block at a time. Blocking is almost universally employed when storing data to 9-track magnetic tape, to turning media such as floppy disks, hard disks, and optical discs, and to NAND flash memory.

Block storage is normally abstract by a file system or database management system for use by applications and end users. Database management systems(DBMS) often use their own Block I/O for superior performance and recoverability as compare to layering the DBMS on top of a file system.

Mortgage

2007-05-16T22:25:00.001-07:00

A mortgage is a method of using property as security for the payment of a debt. The term mortgage refers to the legal tool used in protecting the property, but it is also frequently used to refer to the debt secured by the mortgage, the mortgage loan.

In most jurisdictions mortgages are strongly related with loans secured on real estate rather than other property and in some cases only land may be mortgaged. Arranging a mortgage is seen as the standard method by which individuals or businesses can purchase residential or commercial real estate without the need to pay the full value immediately. See mortgage loan for residential mortgage lending, and commercial mortgage for lending against commercial property.

In many countries it is normal for home purchases to be funded by a mortgage. In countries where the demand for home ownership is highest, strong domestic markets have developed, notably in Spain, the United Kingdom and the United States.
