Configuration Management
Configuration management (CM) is a process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings. Introduction CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle. The CM process facilita ...

Configurational Analysis
In cultural and social studies, configurations are patterns of behaviour, movement (→movement culture) and thinking, which research observes when analysing different cultures and/ or historical changes. The term “configurations” is mostly used by comparative anthropological studies and by cultural history. Configurational analysis became a special method by the Stuttgart school of Historical Behaviour Studies during the 1970s and later by body culture studies in Denmark. Configurational analysis is marked by its distance towards the history of ideas and intentions, which are conceived as mainstreams in historical studies. Configurations of human behaviour and movement have attracted special attention in the framework of Phenomenology (philosophy), phenomenology and particularly in materialist phenomenology. Configurations in earlier cultural studies Configurations in different cultures were studied since early twentieth century. Ruth Benedict (1934) contributed to the ant ...

Configuration (geometry)
In mathematics, specifically projective geometry, a configuration in the plane consists of a finite set of points, and a finite arrangement of lines, such that each point is incident to the same number of lines and each line is incident to the same number of points. Although certain specific configurations had been studied earlier (for instance by Thomas Kirkman in 1849), the formal study of configurations was first introduced by Theodor Reye in 1876, in the second edition of his book ''Geometrie der Lage'', in the context of a discussion of Desargues' theorem. Ernst Steinitz wrote his dissertation on the subject in 1894, and they were popularized by Hilbert and Cohn-Vossen's 1932 book ''Anschauliche Geometrie'', reprinted in English as . Configurations may be studied either as concrete sets of points and lines in a specific geometry, such as the Euclidean or projective planes (these are said to be ''realizable'' in that geometry), or as a type of abstract incidence geometry. ...

Configuration Space (mathematics)
In mathematics, a configuration space is a construction closely related to state spaces or phase spaces in physics. In physics, these are used to describe the state of a whole system as a single point in a high-dimensional space. In mathematics, they are used to describe assignments of a collection of points to positions in a topological space. More specifically, configuration spaces in mathematics are particular examples of configuration spaces in physics in the particular case of several non-colliding particles. Definition For a topological space X, the ''n''th (ordered) configuration space of X is the set of ''n''-tuples of pairwise distinct points in X: :\operatorname_n(X):=\prod^n X \smallsetminus \. This space is generally endowed with the subspace topology from the inclusion of \operatorname_n(X) into X^n. It is also sometimes denoted F(X, n), F^n(X), or \mathcal^n(X). There is a natural action of the symmetric group S_n on the points in \operatorname_n(X) given by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electron Configuration
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is , meaning that the 1s, 2s and 2p subshells are occupied by 2, 2 and 6 electrons respectively. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals. Mathematically, configurations are described by Slater determinants or configuration state functions. According to the laws of quantum mechanics, for systems with only one electron, a level of energy is associated with each electron configuration and in certain conditions, electrons are able to move from one configuration to another by the emission or absorption of a quantum of energy, in the form of a photon. Knowledge of the electron configuration of different atoms is useful in understanding the structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Configuration Space (physics)
In classical mechanics, the parameters that define the configuration of a system are called ''generalized coordinates,'' and the space defined by these coordinates is called the configuration space of the physical system. It is often the case that these parameters satisfy mathematical constraints, such that the set of actual configurations of the system is a manifold in the space of generalized coordinates. This manifold is called the configuration manifold of the system. Notice that this is a notion of "unrestricted" configuration space, i.e. in which different point particles may occupy the same position. In mathematics, in particular in topology, a notion of "restricted" configuration space is mostly used, in which the diagonals, representing "colliding" particles, are removed. Example: a particle in 3D space The position of a single particle moving in ordinary Euclidean 3-space is defined by the vector q=(x,y,z), and therefore its ''configuration space'' is Q=\mathbb^3. ...

Configuration File
In computing, configuration files (commonly known simply as config files) are computer file, files used to configure the Parameter (computer programming), parameters and Initialization (programming), initial settings for some computer programs. They are used for user application software, applications, Server (computing), server processes and operating system settings. Some applications provide tools to create, modify, and verify the syntax of their configuration files; these sometimes have graphical interfaces. For other programs, system administrators may be expected to create and modify files by hand using a text editor, which is possible because many are human-editable plain text files. For server processes and operating-system settings, there is often no standard tool, but operating systems may provide their own graphical interfaces such as YaST or debconf. Some computer programs only read their configuration files at Booting, startup. Others periodically check the configur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Configuration
In communications or computer systems, a configuration of a system refers to the arrangement of each of its functional units, according to their nature, number and chief characteristics. Often, configuration pertains to the choice of hardware, software, firmware, and documentation. Along with its architecture, the configuration of a computer system affects both its function and performance See also * Auto-configuration *Configuration management - In multiple disciplines, a practice for managing change **Software configuration management *Configuration file - In software, a data resource used for program initialization *Configure script (computing) *Configurator *Settings (Windows) References * Federal Standard 1037C Federal Standard 1037C, titled Telecommunications: Glossary of Telecommunication Terms, is a United States Federal Standard issued by the General Services Administration pursuant to the Federal Property and Administrative Services Act of 1949, a ...

Configurator
Configurators, also known as choice boards, design systems, toolkits, or co-design platforms, are responsible for guiding the user through the configuration process. Different variations are represented, visualized, assessed and priced which starts a learning-by-doing process for the user. While the term “configurator” or “configuration system” is quoted rather often in literature, it is used for the most part in a technical sense, addressing a software tool. The success of such an interaction system is, however, not only defined by its technological capabilities, but also by its integration in the whole sale environment, its ability to allow for learning by doing, to provide experience and process satisfaction, and its integration into the brand concept. () Advantages Configurators can be found in various forms and different industries (). They are employed in B2B (business to business), as well as B2C (business to consumer) markets and are operated either by trained staf ...

Configuration (polytope)
In geometry, H. S. M. Coxeter called a regular polytope a special kind of configuration. Other configurations in geometry are something different. These ''polytope configurations'' may be more accurately called incidence matrices, where like elements are collected together in rows and columns. Regular polytopes will have one row and column per ''k''-face element, while other polytopes will have one row and column for each k-face type by their symmetry classes. A polytope with no symmetry will have one row and column for every element, and the matrix will be filled with 0 if the elements are not connected, and 1 if they are connected. Elements of the same ''k'' will not be connected and will have a "*" table entry. Every polytope, and abstract polytope has a Hasse diagram expressing these connectivities, which can be systematically described with an incidence matrix. Configuration matrix for regular polytopes A configuration for a regular polytope is represented by a matrix whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Configuration
The molecular configuration of a molecule is the ''permanent'' geometry that results from the spatial arrangement of its bonds. The ability of the same set of atoms to form two or more molecules with different configurations is stereoisomerism. Used as drugs, compounds with different configuration normally have ''different'' physiological activity, including the desired pharmacological effect, the toxicology and the metabolism.Everhardus Ariëns: ''Stereochemistry, the basis for sophisticated nonsense in pharmacokinetics and clinical pharmacology'', European Journal of Clinical Pharmacology 26 (1984) 663-668, . Configuration is distinct from chemical conformation, a shape attainable by bond rotations. See also * Absolute configuration Absolute configuration refers to the spatial arrangement of atoms within a chiral molecular entity (or group) and its resultant stereochemical description. Absolute configuration is typically relevant in organic molecules, where carbon is bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
