Organic (model)
Organic describes forms, methods and patterns found in living systems such as the organisation of cells, to populations, communities, and ecosystems. Typically organic models stress the interdependence of the component parts, as well as their differentiation. Other properties of organic models include: *the growth, life or development cycle *the ability to adapt, learn, and evolve *emergent behaviour or emergent properties *steady change or growth, as opposed to instant change *regulatory feedback *composed of heterogeneous (diverse) parts Organic models are used especially in the design of artificial systems, and the description of social systems and constructs. Uses In the social sciences, the organic model has been drawn upon for ideas such as mechanical and organic solidarity and organic unity. Carl Ritter advanced the idea of Lebensraum using the metaphor of an organic, growing state. In computer science, organic networks grow in an ad hoc manner, while organic computing ...

Cell (biology)
The cell is the basic structural and functional unit of life forms. Every cell consists of a cytoplasm enclosed within a membrane, and contains many biomolecules such as proteins, DNA and RNA, as well as many small molecules of nutrients and metabolites.Cell Movements and the Shaping of the Vertebrate Body in Chapter 21 of Molecular Biology of the Cell '' fourth edition, edited by Bruce Alberts (2002) published by Garland Science. The Alberts text discusses how the "cellular building blocks" move to shape developing embryos. It is also common to describe small molecules such as ...

Bionics
Bionics or biologically inspired engineering is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. The word ''bionic'', coined by Jack E. Steele in August 1958, is a portmanteau from ''biology'' and ''electronics'' that was popularized by the 1970s U.S. television series ''The Six Million Dollar Man'' and ''The Bionic Woman'', both based upon the novel ''Cyborg'' by Martin Caidin. All three stories feature humans given various superhuman powers by their electromechanical implants. According to proponents of bionic technology, the transfer of technology between lifeforms and manufactured objects is desirable because evolutionary pressure typically forces living organisms – fauna and flora – to become optimized and efficient. For example, dirt- and water-repellent paint (coating) developed from the observation that practically nothing sticks to the surface of the lotus flower plant (the lot ...

Organic Law
An organic law is a law, or system of laws, that form the foundation of a government, corporation or any other organization's body of rules. A constitution is a particular form of organic law for a sovereign state. By country France Under Article 46 of the Constitution of France, organic laws (in French, ''lois organiques''; in English sometimes translated as Institutional Acts) are a short, fixed list of statutes (in 2005, there were about 30 of them) specified in the Constitution. They overrule ordinary statutes. They must be properly enacted by the Parliament of France following a special procedure and must be approved for constitutionality by the Constitutional Council of France before they can be promulgated. Organic laws allow flexibility if needed. An important category of organic laws includes the budgets of the French state and French social security. Other organic laws give the practical procedures for various elections. Organic laws reduce the need for amendments to the ...

Cybernetics
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics. London: Chapman & Hall, p. 1. including in ecological, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, conversation, and the practice of cybernetics itself. Cybernetics' transdisciplinary and "antidisciplinary" character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

Genetic Algorithm
In computer science and operations research, a genetic algorithm (GA) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high-quality solutions to optimization and search problems by relying on biologically inspired operators such as mutation, crossover and selection. Some examples of GA applications include optimizing decision trees for better performance, solving sudoku puzzles, hyperparameter optimization, etc. Methodology Optimization problems In a genetic algorithm, a population of candidate solutions (called individuals, creatures, organisms, or phenotypes) to an optimization problem is evolved toward better solutions. Each candidate solution has a set of properties (its chromosomes or genotype) which can be mutated and altered; traditionally, solutions are represented in binary as strings of 0s and 1s, but other encodings are also possible. ...

Military Unit
Military organization or military organisation is the structuring of the armed forces of a state so as to offer such military capability as a national defense policy may require. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as insurgent forces, often mimic military organizations, or use ''ad hoc'' structures, while formal military organization tends to use hierarchical forms. History The use of formalized ranks in a hierarchical structure came into widespread use with the Roman Army. In modern times, executive control, management and administration of military organization is typically undertaken by governments through a government department within the structure of public administration, often known as a ministry of defence or department of defense. These in turn manage military branches that themselves command formations a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organic (military)
An organic unit is a military unit that is a permanent part of a larger unit and (usually) provides some specialized capability to that parent unit. For instance, the US Marine Corps incorporates its own aviation units (distinct from the US Air Force and US Navy) that provide it with fire support, electronic warfare, and transport. Description At a lower level of organization, infantry units commonly incorporate organic armour or artillery units to improve their combined arms capability. Organic assets are closely integrated into their parent unit's command structure and their personnel are familiar with other personnel in the parent unit, improving coordination and responsiveness and making the parent unit more self-sufficient. However, over-emphasis of organic assets can create wasteful redundancy. For instance, an infantry unit assigned to urban peacekeeping duties might have little use for its organic artillery, while another unit deployed elsewhere might have less artillery ...

Organic Organisation
A term created by Tom Burns and G.M. Stalker in the late 1950s, organic organizations (Organic system theory), unlike mechanistic organizations (also coined by Burns and Stalker), are flexible and value external knowledge. The theories of Burns and Stalker impacted the field of organization theory, with their study of management and structure of Scottish electronics firms. In their writing contrasting mechanistic and organismic structures, they outlined the differences between the two types. Also called organismic organization, this form of organizational structure was widely sought and proposed, but difficult to prove it exists. As opposed to the mechanistic organization, it has the least hierarchy and specialization of functions. For an organization to be organic, the participants or workers should have equal levels, with no job descriptions or classifications, and communication should have a hub-network-like form. Organic organisation thrives on the power of personalities an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organic Growth
Organic business growth is related to the growth of natural systems and organisms, societies and economies, as a dynamic organizational process, that for business expansion is marked by increased output, customer base expansion, or new product development, as opposed to mergers and acquisitions, which is inorganic growth. For businesses organic growth typically excludes the impact of foreign exchange. "Core growth" is the term that is used to refer to growth that includes foreign exchange, but excludes divestitures and acquisitions. Organic business growth is growth that comes from a company's existing businesses, as opposed to growth that comes from buying new businesses. It may be negative. Through Growth planning, businesses are able to achieve organic growth by selecting the best strategies available to them. For example, by examining Ansoff's matrix, businesses can select from market penetration, market development, product development and diversification to grow their revenue ...

Passive Solar
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis. Elements to be considered include window placement and size, and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be adapted or "retrofitted". Passive energy gain ''Passive solar'' technologies use sunlight without active mechanical systems (as contrasted to ''active solar'', which uses thermal collectors). Such technologies convert sunlight into usable heat (in water, air, and thermal mass), cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organic Architecture
Organic architecture is a philosophy of architecture which promotes harmony between human habitation and the natural world. This is achieved through design approaches that aim to be sympathetic and well-integrated with a site, so buildings, furnishings, and surroundings become part of a unified, interrelated composition. An organicist is an architect in the organic movement. History The term "organic architecture" was coined by Frank Lloyd Wright (1867–1959), though never well-articulated by his cryptic style of writing: So here I stand before you preaching organic architecture: declaring organic architecture to be the modern ideal and the teaching so much needed if we are to see the whole of life and to now serve the whole of life, holding no traditions essential to the great TRADITION. Nor cherishing any preconceived form fixing upon us either past, present, or future, but instead exalting the simple laws of common sense or of super-sense if you prefer determining form by wa ...

Biology
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
