Engineering ... The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.. ...

Social Psychology ... Social psychologists typically explain human behavior as a result of the interaction of mental states and immediate social situations. In Kurt Lewin's conceptual formula, behavior (B) can be viewed as a function (f) of the person (P) in the environment (E), B = f (P, E)...

NASA ... Since February 2006, NASA's mission statement has been to "pioneer the future in space exploration, scientific discovery and aeronautics research." On September 14, 2011, NASA announced that it had selected the design of a new Space Launch System that it said would take the agency's astronauts farther into space than ever before and provide the cornerstone for future human space exploration efforts by the U. S. NASA was established by the National Aeronautics and Space Act on July 29, 1958, replacing its predecessor, the National Advisory Committee for Aeronautics (NACA). The agency became operational on October 1, 1958...

Business Intelligence ... BI technologies provide historical, current and predictive views of business operations. Common functions of business intelligence technologies are reporting, online analytical processing, analytics, data mining, process mining, complex event processing, business performance management, benchmarking, text mining and predictive analytics...

Website ... A webpage is a document, typically written in plain text interspersed with formatting instructions of Hypertext Markup Language (HTML, XHTML). A webpage may incorporate elements from other websites with suitable markup anchors...

Holography ... The holographic recording itself is not a plain image – it consists of an apparently random structure of either varying intensity, density or profile. Overview and history The Hungarian-British physicist Dennis Gabor (Hungarian name: Gábor Dénes), was awarded the Nobel Prize in Physics in 1971 for "for his invention and development of the holographic method"...

Database ... The term database is correctly applied to the data and their supporting data structures, and not to the database management system (DBMS). The database data collection with DBMS is called a database system...

Satellite ... The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth; also some satellites, notably space stations, have been launched in parts and assembled in orbit...

Mathematical Optimization ... The domain A of f is called the search space or the choice set, while the elements of A are called candidate solutions or feasible solutions...

Search Warrant ... Jurisdictions that respect the rule of law and a right to privacy put constraints on the powers of police investigators, and typically require search warrants, or an equivalent procedure, for searches conducted as part of a criminal investigation... Conversely, in authoritarian regimes, the police typically have the right to search property and people without having to provide justification, or without having to secure the permission of a court... United Kingdom Search warrants are issued by a local Magistrate and require a Constable to provide evidence to support the warrant application...

DNA ... DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel...

Blog ... The emergence and growth of blogs in the late 1990s coincided with the advent of web publishing tools that facilitated the posting of content by non-technical users. (Previously a knowledge of such technologies as HTML and FTP had been required to publish content on the Web.) Although not a must, most good quality blogs are interactive, allowing visitors to leave comments and even message each other via GUI widgets on the blogs and it is this interactivity that distinguishes them from other static websites...

Privacy ... The right not to be subjected to unsanctioned invasion of privacy by the government, corporations or individuals is part of many countries' privacy laws, and in some cases, constitutions. Almost all countries have laws which in some way limit privacy; an example of this would be law concerning taxation, which normally require the sharing of information about personal income or earnings...

Cryptanalysis ... Cryptanalysis is also used to refer to any attempt to circumvent the security of other types of cryptographic algorithms and protocols in general, and not just encryption. However, cryptanalysis usually excludes methods of attack that do not primarily target weaknesses in the actual cryptography, such as bribery, physical coercion, burglary, keystroke logging, and social engineering, although these types of attack are an important concern and are often more effective than traditional cryptanalysis...

Artificial Intelligence ... The field was founded on the claim that a central property of humans, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine. This raises philosophical issues about the nature of the mind and the ethics of creating artificial beings, issues which have been addressed by myth, fiction and philosophy since antiquity...

Subscriber Identity Module ... A SIM is embedded into a removable SIM card, which can be transferred between different mobile devices. SIM cards were first made the same size as a credit card (85.60 mm × 53.98 mm × 0.76 mm)...

European Space Agency ... ESA's space flight program includes human spaceflight, mainly through the participation in the International Space Station program, the launch and operations of unmanned exploration missions to other planets and the Moon, Earth observation, science, telecommunication as well as maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana, and designing launch vehicles. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle...

Search Engine Technology ... Some search engines go through the indexing process every few weeks and refresh the complete index used for web search requests while others keep updating small fragments of the index continuously... Before web pages can be indexed, an algorithm decides which node (a server in a distributed service) will index any given page and makes the information available as metadata for other components in the search engine... The choice of compression algorithm involves a trade-off between on-disk storage space and speed of decompression when needed to satisfy search requests...
