Computational Fluid Dynamics
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid ( liquids and gases) with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved, and are often required to solve the largest and most complex problems. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is typically performed using experimental apparatus such as wind tunnels. In addition, previously performed analytical or empirical analysis of a particular problem can be used for comparison. A final validation is often performed using full-scale testing, such as flight tests. CFD is applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (Berkeley Software Distribution, BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris (operating system), Solaris), Hewlett-Packard, HP/Hewlett Packard Enterprise, HPE (HP-UX), and IBM (IBM AIX, AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are chara ...

David Gosman
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges David and Jonathan, a notably close friendship with Jonathan (1 Samuel), Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of History of ancie ...

3840x1080 F16 OpenFOAM
__NOTOC__ Year 384 ( CCCLXXXIV) was a leap year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Ricomer and Clearchus (or, less frequently, year 1137 ''Ab urbe condita''). The denomination 384 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for giving names to years. Events By place Roman Empire * Magnus Maximus elevates his son Flavius Victor to the rank of ''Augustus''. * Magnus Maximus returns to Britain, to aid the Roman army with the barbarian raids triggered by Maximus' withdrawal of troops to the continent. * The Forum of Theodosius ("Forum of the Bull") is built in Constantinople. * Quintus Aurelius Symmachus becomes urban prefect of Rome. * An edict of Theodosius I closes pagan temples in the Nile Valley (Egypt). * Stilicho marries Serena, adopted niece of Theodosius I.

Software Versioning
Software versioning is the process of assigning either unique ''version names'' or unique ''version numbers'' to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software. At a fine-grained level, revision control is often used for keeping track of incrementally-different versions of information, whether or not this information is computer software. Modern computer software is often tracked using two different software versioning schemes: an ''internal version number'' that may be incremented many times in a single day, such as a revision control number, and a ''release version'' that typically changes far less often, such as semantic versioning or a project code name. History File numbers were used especially in public administration, as well as companies, to uniquely identify files or cases. For computer files this practice was i ...

Private Company Limited By Guarantee
In British, Australian, Bermudian, Hong Kong and Irish company law (and previously New Zealand), a company limited by guarantee (CLG) is a type of corporation used primarily (but not exclusively) for non-profit organisations that require legal personality. A company limited by guarantee does not usually have a share capital or shareholders, but instead has members who act as guarantors of the company's liabilities: each member undertakes to contribute an amount specified in the articles (typically very small) in the event of insolvency or of the winding up of the company. A company limited by guarantee can distribute its profits to its members, if allowed to by its articles of association, but then it would not be eligible for charitable status. Like a private company limited by shares, a company limited by guarantee must include the suffix " Limited" in its name, except in circumstances specifically excluded by law. One condition of this exclusion is that the company does n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Code
In computing, source code, or simply code, is any collection of code, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code that can be executed by the computer. The machine code is then available for execution at a later time. Most application software is distributed in a form that includes only executable files. If the source code were included it would be useful to a user, programmer or a system administrator, any of whom might wish to study or modify the program. Alternatively, depending on the technology being used, source code may be interpreted and executed directly. Definitions Richard Stallman's definition, formulated in his 1989 seminal li ...

Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that (ty ...
