Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

At (command)
In computing, at is a command in Unix-like operating systems, Microsoft Windows, and ReactOS used to schedule commands to be executed once, at a particular time in the future. Design Unix-like On Unix-like operating systems, at reads a series of commands from standard input and collects them into one "at-job" which is carried out at a later date. The job inherits the current environment, so that it is executed in the same working directory and with the same environment variables set as when it was scheduled. It differs from cron, which is used for recurring executions (e.g. once an hour, every Tuesday, January 1 every year). As with cron, many Unix systems allow the administrator to restrict access to the at command. at can be made to mail a user when done carrying out a scheduled job, can use more than one job queue, and can read a list of jobs to carry out from a computer file instead of standard input. The Linux at command was mostly written by Thomas Koenig. Microsoft Windo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Trail
The Appalachian Trail (also called the A.T.), is a hiking trail in the Eastern United States, extending almost between Springer Mountain in Georgia and Mount Katahdin in Maine, and passing through 14 states.Gailey, Chris (2006)"Appalachian Trail FAQs" Outdoors.org (accessed September 14, 2006) The Appalachian Trail Conservancy claims the Appalachian Trail to be the longest hiking-only trail in the world. More than three million people hike segments of the trail each year. The trail was first proposed in 1921 and completed in 1937 after more than a decade of work. Improvements and changes have continued since then. It became the Appalachian National Scenic Trail under the National Trails System Act of 1968. The trail is maintained by 31 trail clubs and multiple partnerships, and managed by the National Park Service, United States Forest Service, and the nonprofit Appalachian Trail Conservancy. Most of the trail is in forest or wild lands, although some portions traverse towns, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appropriate Technology
Appropriate technology is a movement (and its manifestations) encompassing technological choice and application that is small-scale, affordable by locals, decentralized, labor-intensive, energy-efficient, environmentally sustainable, and locally autonomous. It was originally articulated as intermediate technology by the economist Ernst Friedrich "Fritz" Schumacher in his work ''Small Is Beautiful.'' Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered. Appropriate technology has been used to address issues in a wide range of fields. Well-known examples of appropriate technology applications include: bike- and hand-powered water pumps (and other self-powered equipment), the universal nut sheller, self-contained solar lamps and streetlights, and passive solar building designs. Today appropriate technology is often developed using open source principles, which have led to ''open-source appropriate technology'' ( ...

At Sign
The at sign, , is normally read aloud as "at"; it is also commonly called the at symbol, commercial at, or address sign. It is used as an accounting and invoice abbreviation meaning "at a rate of" (e.g. 7 widgets @ £2 per widget = £14), but it is now seen more widely in email addresses and social media platform handles. The absence of a single English word for the symbol has prompted some writers to use the French ''arobase'' or Spanish and Portuguese ''arroba'', or to coin new words such as ''ampersat'' and ''asperand'', or the (visual) onomatopoeia ''strudel'', but none of these have achieved wide use. Although not included on the keyboard of the earliest commercially successful typewriters, it was on at least one 1889 model"The @-symbol, part 2 of 2" , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank Warfare
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft. Anti-tank warfare evolved rapidly during World War II, leading to the inclusion of infantry-portable weapons such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acceptance Testing
In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests, physical tests, or performance tests. In systems engineering, it may involve black-box testing performed on a system (for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. In software testing, the ISTQB defines ''acceptance testing'' as: Acceptance testing is also known as user acceptance testing (UAT), end-user testing, operational acceptance testing (OAT), acceptance test-driven development (ATDD) or field (acceptance) testing. Acceptance criteria are the criteria that a system or component must satisfy in order to be accepted by a user, customer, or other authorized entity. Overview Testing is a set of activities conducted to facilitate discovery and/or evaluation of properties of one or more items under test ...

Anguilla
Anguilla ( ) is a British Overseas Territory in the Caribbean. It is one of the most northerly of the Leeward Islands in the Lesser Antilles, lying east of Puerto Rico and the Virgin Islands and directly north of Saint Martin. The territory consists of the main island of Anguilla, approximately long by wide at its widest point, together with a number of much smaller islands and cays with no permanent population. The territory's capital is The Valley. The total land area of the territory is , with a population of approximately (). Etymology The native Arawak name for the island was ''Malliouhana''. In reference to the island's shape, the Italian ', meaning "eel" (in turn, from the Latin diminutive of ''anguis'', "snake") was used as its name. History Anguilla was first settled by Indigenous Amerindian peoples who migrated from South America. The earliest Native American artefacts found on Anguilla have been dated to around 1300 BC; remains of settlements da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Province Of Asti
The Province of Asti ( it, Provincia di Asti, Piedmontese: ''Provincia d’Ast'') is a province in the Piedmont region of northern Italy. Its capital is the city of Asti. To the northwest it borders on the Metropolitan City of Turin; to the southwest it borders on the province of Cuneo. To the east it borders on the province of Alessandria, while in the south it shares a very short border with the Ligurian province of Savona. It has an area of , and, , a total population of 215,871. History The Province of Asti was re-established on 1 April 1935 by Royal Decree No. 297 of King Victor Emmanuel III. It was detached from the existing Province of Alessandria into which it had been absorbed upon the creation of that province in 1859. The Province of Asti is among the institutions awarded the Gold Medal for Military Valor (''Medaglia d'Oro al Valor Militare'') for its contribution to the partisan struggle during the last two years of the Second World War.

IBM Personal Computer/AT
The IBM Personal Computer/AT (model 5170, abbreviated as IBM AT or PC/AT) was released in 1984 as the fourth model in the IBM Personal Computer line, following the IBM PC/XT and its IBM Portable PC variant. It was designed around the Intel 80286 microprocessor. Name IBM did not specify an expanded form of "AT" on the machine, press releases, brochures or documentation, but some sources expand the term as "Advanced Technology", including at least one internal IBM document. History IBM's 1984 introduction of the AT was seen as an unusual move for the company, which typically waited for competitors to release new products before producing its own models. At $4,000–6,000, it was only slightly more expensive than considerably slower IBM models. The announcement surprised rival executives, who admitted that matching IBM's prices would be difficult. No major competitor showed a comparable computer at COMDEX Las Vegas that year. Features The AT is IBM PC compatible, with the mo ...

Hayes Command Set
The Hayes command set (also known as the AT command set) is a specific command language originally developed by Dennis Hayes for the Hayes Smartmodem 300 baud modem in 1981. The command set consists of a series of short text strings which can be combined to produce commands for operations such as dialing, hanging up, and changing the parameters of the connection. The vast majority of dial-up modems use the Hayes command set in numerous variations. The command set covered only those operations supported by the earliest 300 bit/s modems. When new commands were required to control additional functionality in higher speed modems, a variety of one-off standards emerged from each of the major vendors. These continued to share the basic command structure and syntax, but added any number of new commands using some sort of prefix character – & for Hayes and USR, and \ for Microcom, for instance. Many of these were re-standardized on the Hayes extensions after the introduction of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transactional Analysis
Transactional Analysis (TA) is a psychoanalytic theory and method of therapy wherein social interactions (or “transactions”) are analyzed to determine the ego state of the communicator (whether parent-like, childlike, or adult-like) as a basis for understanding behavior. In transactional analysis, the communicator is taught to alter the ego state as a way to solve emotional problems. The method deviates from Freudian psychoanalysis which focuses on increasing awareness of the contents of subconsciously held ideas. Eric Berne developed the concept and paradigm of transactional analysis in the late 1950s. History Eric Berne presented Transactional Analysis to the world as a phenomenological approach, supplementing Freud's philosophical construct with observable data. His theory built on the science of Wilder Penfield and René Spitz along with the neo-psychoanalytic thought of people such as Paul Federn, Edoardo Weiss, and Erik Erikson.
