Information and Communication technology

From Wikipedia, the free encyclopedia

Information and Communications Technology - or technologies (ICT) is an umbrella term that includes all technologies for the communication of information. It encompasses: any medium to record information (whether paper, pen, magnetic disk/ tape, optical disks - CD/DVD, flash memory etc. etc.); and also technology for broadcasting information - radio, television,; any technology for communicating through voice and sound or images- microphone, camera, loudspeaker, telephone to cellular phones. At present, it appears to be culminating with the advent of information technology that is based on Personal Computers (PCs) to computers networked through the Internet using satellite systems or intercontinental cables. Indeed ever since information technology (IT) has become a kind of a hub for communicating information, most often using computers, it has apparently become a dominant medium for communicating information. But, with an expanding fraction of population getting interested in sharing information it may not continue to be so.

ICT Application In Mechatronic Engineering

Robotics is the science and technology of robots, manufacture, and application. A person working in the field is a roboticist. Although the appearance and capabilities of robots vary vastly, all robots share the features of a mechanical, movable structure under some form of autonomous control. The mechanical structure of a robot must be controlled to perform tasks. The control of a robot involves three distinct phases - perception, processing and action (robotic paradigms). Sensors give information about the environment or the robot itself. Using strategies from the field of control theory, this information is processed to calculate the appropriate signals to the actuators or motors which move the mechanical structure. The control of a robot involves path planning, pattern recognition, obstacle avoidance and others.

Industrial Automation or numerical control is the use of control systems such as computers to control industrial machinery and processes, replacing human operators. In the scope of industrialization, it is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well. Processes and systems can also be automated.

Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information. The information technology umbrella can be quite large, covering many fields. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.

The basic of robotic and industrial automation is basic computer programming. The purpose of programming is to create a program that exhibits a certain desired behavior (customization). The process of writing source codes requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.. The most basic Programming languages is C and C++. In industrial automation, software or program are needed to control the machine as to order the machine to do the certain tasks. The first step in most formal software development projects is requirements analysis, followed by modeling, implementation, and failure elimination (debugging). There exist a lot of differing approaches for each of those tasks. One approach popular for requirements analysis is Use Case analysis. Popular modeling techniques include Object-Oriented Analysis and Design (OOAD) and Model-Driven Architecture (MDA). The Unified Modeling Language (UML) is a notation used for both OOAD and MDA. A similar technique used for database design is Entity-Relationship Modeling (ER Modeling). Implementation techniques include imperative languages (object-oriented or procedural), functional languages, and logic languages.

Debugging is most often done with IDEs like Visual Studio, NetBeans, and Eclipse. Separate debuggers like gdb are also used.

Other part in robotics and industrial automation is Programmable Logic Control (PLC). PLC is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result. PLCs were invented as replacements for automated systems that would use hundreds or thousands of relays, cam timers, and drum sequencers. Often, a single PLC can be programmed to replace thousands of relays.

Defense of the Ancients

Defense of the Ancients

DotA Allstars loading screen




Defense of the Ancients (often referred to as DotA) is a custom scenario for Warcraft III: The Frozen Throne, based on the "Aeon of Strife" map for StarCraft. The objective of the scenario is to destroy the opponents' "Ancient", a heavily guarded structure in each corner of the map. Players use powerful units known as heroes, and are assisted by allied heroes and AI-controlled fighters called "creeps". As in role playing games, players level up their hero and use gold to buy equipment during the mission.[1]

The scenario was developed with the World Editor of Warcraft III: Reign of Chaos, and was updated upon the release of The Frozen Throne. There have been many variations of the original concept, the most popular of which is DotA Allstars,[2] which has been maintained by several authors during development. Since its release, Allstars has become a feature at several worldwide tournaments, including Blizzard Entertainment's Blizzcon and the Asian World Cyber Games, as well as the Cyberathlete Amateur and CyberEvolution leagues.

Development

Warcraft III is the third title in the Warcraft series of real-time strategy games developed by Blizzard Entertainment. As with Warcraft II, Blizzard included a free "world editor" in the game that allows players to create custom scenarios or "maps" for the game, which can be played online with other players through Battle.net.[3] These custom scenarios can be simple terrain changes, which play like normal Warcraft games, or they can be entirely new game scenarios with custom objectives, units, items, and events;[3] Defense of the Ancients is one of the latter. Created by a mapmaker known as Eul, Defense of the Ancients is a custom scenario based on a previous StarCraft scenario known as "Aeon of Strife".[4] After the release of Warcraft's expansion The Frozen Throne, which added new features to the World Editor, Eul did not update the scenario.[2] Numerous variants were created based on the original, but Allstars is the version that made Defense of the Ancients popular. Allstars was developed by an author under the alias Guinsoo. After version 6.x, another author by the name of IceFrog took over development of the scenario.[2] With successive versions, IceFrog fixes bugs and adds or updates features; for example, in version 6.48, IceFrog added a feature which automatically changes the terrain from grass to snow. Each release is accompanied with a changelog.[5] On the Allstars forum, users can post ideas for new heroes or items, some of which are added to the map.[6] Versions of the scenario where enemy heroes are controlled by artificial intelligences have also been released.

Gameplay

Defense of the Ancients pits two teams of players against each other: the Sentinel and the Scourge. Players on the Sentinel team are based at the southwest corner of the map, and those on the Scourge team are based at the northeast corner. Each base is defended by towers and waves of units which guard the main paths leading to their base. In the center of each base is the "Ancient", a building that must be destroyed to win the game.[7][8]

Each human player controls one Hero, a powerful unit with unique abilities. In Allstars, players on each side choose one of ninety heroes, each with different abilities and tactical advantages over other heroes.[9] The scenario is highly team-oriented; it is difficult for one player to carry the team to victory alone.[10] Nevertheless, some heroes, given enough time, can change the outcome single-handedly, while countering the opposing team's heroes. Defense of the Ancients allows up to ten players in a five versus five format and an additional two slots for referees or observers, often with an even number of players on each side.[2]

Because the gameplay revolves around strengthening individual heroes, it does not require one to focus on resource management and base-building, as in most traditional real-time strategy games.[6] Killing computer-controlled units earns the player experience points; when enough experience is accumulated, the player gains a level. Leveling up improves the hero's toughness and the damage it can inflict, and allows players to upgrade their spells or skills. In addition to accumulating experience, players also manage a single resource: gold. The typical resource gathering of Warcraft III is replaced by a combat-oriented money system; in addition to a small periodic income, heroes earn gold by killing hostile units, base structures, and enemy heroes.[11] Using gold, players buy items to strengthen their hero and gain abilities. Certain items can be combined with recipes to create more powerful items. Buying items that suit one's hero is an important tactical element of the scenario.[6][12]

Allstars offers a variety of game modes, selected by the game host at the beginning of the match. The game modes dictate the difficulty of the scenario, as well as whether people can choose their hero or are assigned one randomly. Many game modes can be combined (for example, an easy difficulty level and a random hero pick), allowing more flexible options.[4]

Reception

The popularity of Defense of the Ancients has increased over time. The scenario was featured by Computer Gaming World in a review of new maps and mods in Warcraft III,[13] and has been called "the ultimate RTS".[14] Allstars has become an important tournament scenario, starting with its prominence at the debut of Blizzard's BlizzCon convention in 2005.[15] Allstars was also featured in the Malaysia and Singapore World Cyber Games starting in 2005, and the World Cyber Games Asian Championships beginning with the 2006 season.[16] Defense of the Ancients is now included in the game lineup for the internationally recognized Cyberathlete Amateur League and CyberEvolution leagues.[17] Additionally, the scenario is slated to appear in Electronic Sports World Cup (ESWC) 2008;[18][19] Oliver Paradis, ESWC's competition manager, noted that the high level of community support behind the scenario, as well as its worldwide appeal, were among the reasons it was chosen.[20] LAN tournaments are a major part of worldwide play,[20] including tournaments in Sweden and Russia; however, due to a lack of LAN tournaments and championships in North America, several teams have since disbanded.[21]

The scenario is popular in many parts of the world; in the Philippines and Thailand, it is played as much as the game Counter-Strike.[21][22] It is also popular in Sweden and other Northern European countries, where the Defense of the Ancients-inspired song "Vi sitter i Ventrilo och spelar DotA" by Swedish musician Basshunter reached the European 2006 charts at #116 and cracked the top ten Singles Charts in Sweden, Norway,[23] and Finland.[24] Defense of the Ancients has been credited as one of the influences for the upcoming Gas Powered Games title Demigod.[25][26]

Manchester United's emblem

Manchester United Football Club is an English football club, based at the Old Trafford stadium in Trafford, Greater Manchester, and is arguably the most popular football club in the world, with over 330 million supporters worldwide; 5% of the world's population.[2] The club was a founding member of the Premier League in 1992, and has played in the top division of English football since 1975. Average attendances at the club have been higher than any other team in English football for all but six seasons since 1964–65.[3]

The club is the second most successful in the history of English football and by far the most successful of recent times, having won 18 major honours since the start of Alex Ferguson's reign as manager in November 1986.[4] They are the Premier League's reigning champions, and have won the Premier League/Football League 16 times. In 1968, they became the first English club to win the European Cup, beating S.L. Benfica 4–1, and they won a second European Cup in 1999. They also hold the record for the most FA Cup titles with 11.[5]

Since the late 1990s, the club has been one of the richest in the world with the highest revenue of any football club,[6], and is currently the second richest club in the world, based on revenue.[7] Manchester United, which remains the most valuable club in the world,[8] was a founding member of the now-defunct G-14 group of Europe's leading football clubs and its replacement, the European Club Association.

Sir Alex Ferguson has been manager of the club since 6 November 1986. The current club captain is Gary Neville, who succeeded Roy Keane in November 2005.[9]
