Chaotic Good
In the ''Dungeons & Dragons'' (''D&D'') fantasy role-playing game, alignment is a categorization of the ethics, ethical and morality, moral perspective of player characters, non-player characters, and creatures. Most versions of the game feature a system in which players make two choices for characters. One is the character's views on "law" versus "Lawlessness, chaos", the other on "good" versus "evil". The two axes, along with "neutral" in the middle, allow for nine alignments in combination. Later editions of ''D&D'' have shifted away from tying alignment to specific game mechanics; instead, alignment is used as a roleplaying guide and does not need to be rigidly adhered to by the player. According to Ian Livingstone, alignment is "often criticized as being arbitrary and unreal, but... it works if played well and provides a useful structural framework on which not only characters but governments and worlds can be moulded." History ''D&D'' co-creator Gary Gygax credited the ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Group
The carbon group is a group (periodic table), periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). It lies within the p-block. In modern International Union of Pure and Applied Chemistry, IUPAC notation, it is called group 14. In the field of Semiconductor#Physics of semiconductors, semiconductor physics, it is still universally called group IV. The group is also known as the tetrels (from the Greek word ''tetra'', which means four), stemming from the Roman numeral IV in the group name, or (not coincidentally) from the fact that these elements have four valence electrons (see below). They are also known as the crystallogens or adamantogens. Characteristics Chemical Like other groups, the members of this family show patterns in electron configuration, especially in the outermost shells, resulting in trends in chemical behavior: Each of the chemical element, elements in this group has 4 electrons in its ...

Cloud-to-ground Lightning
Lightning is a natural phenomenon consisting of electrostatic discharges occurring through the atmosphere between two electrically charged regions. One or both regions are within the atmosphere, with the second region sometimes occurring on the ground. Following the lightning, the regions become partially or wholly electrically neutralized. Lightning involves a near-instantaneous release of energy on a scale averaging between 200 megajoules and 7 gigajoules. The air around the lightning flash rapidly heats to temperatures of about . There is an emission of electromagnetic radiation across a wide range of wavelengths, some visible as a bright flash. Lightning also causes thunder, a sound from the shock wave which develops as heated gases in the vicinity of the discharge experience a sudden increase in pressure. The most common occurrence of a lightning event is known as a thunderstorm, though they can also commonly occur in other types of energetic weather systems, such as ...

Center Of Mass
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weight function, weighted relative position (vector), position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the Phys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centigram
To help compare different ''orders of magnitude'', the following lists describe various ''mass'' levels between 10−67 kg and 1052 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe. Typically, an object having greater mass will also have greater weight (see mass versus weight), especially if the objects are subject to the same gravitational field strength. Units of mass The table at right is based on the kilogram (kg), the base unit of mass in the International System of Units ( SI). The kilogram is the only standard unit to include an SI prefix (''kilo-'') as part of its name. The ''gram'' (10−3 kg) is an SI derived unit of mass. However, the ''names'' of all SI mass units are based on ''gram'', rather than on ''kilogram''; thus 103 kg is a ''megagram'' (106 g), not a *''kilokilogram''. The ''tonne'' (t) is an SI-compatible unit of mass equal to a megagram (''Mg''), or 103 kg. The unit is in common use fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clock Gating
In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation (a significant source of power dissipation in digital designs), by removing the clock signal when the circuit, or a subpart of it, is idle. Clock gating Energy conservation, saves power by pruning part of the Clock_signal#Distribution, clock tree distribution, at the cost of adding more logic to a circuit. Pruning the clock turns off portions of the circuitry so that the Flip-flop (electronics), flip-flops in them do not switch state, as switching the state consumes power. When not switched, the switching power consumption is reduced. This technique is particularly effective in systems with significant idle time or predictable periods of inactivity within specific module Essential details Digital circuits consume power through multiple mechanisms, typically categorised into dynamic and static components. The equation can describ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conjugate Gradient Method
In mathematics, the conjugate gradient method is an algorithm for the numerical solution of particular systems of linear equations, namely those whose matrix is positive-semidefinite. The conjugate gradient method is often implemented as an iterative algorithm, applicable to sparse systems that are too large to be handled by a direct implementation or other direct methods such as the Cholesky decomposition. Large sparse systems often arise when numerically solving partial differential equations or optimization problems. The conjugate gradient method can also be used to solve unconstrained optimization problems such as energy minimization. It is commonly attributed to Magnus Hestenes and Eduard Stiefel, who programmed it on the Z4, and extensively researched it. The biconjugate gradient method provides a generalization to non-symmetric matrices. Various nonlinear conjugate gradient methods seek minima of nonlinear optimization problems.

Conceptual Graph
A conceptual graph (CG) is a formalism for knowledge representation. In the first published paper on CGs, John F. Sowa used them to represent the conceptual schemas used in database systems. The first book on CGs applied them to a wide range of topics in artificial intelligence, computer science, and cognitive science. Research branches Since 1984, the model has been developed along three main directions: a graphical interface for first-order logic, a diagrammatic calculus of logics, and a graph-based knowledge representation and reasoning model. Graphical interface for first-order logic In this approach, a formula in first-order logic (predicate calculus) is represented by a labeled graph. A linear notation, called the Conceptual Graph Interchange Format (CGIF), has been standardized in the ISO standard for common logic. The diagram above is an example of the ''display form'' for a conceptual graph. Each box is called a ''concept node'', and each oval is called a ''re ...

Computer-generated Imagery
Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in Digital art, art, Publishing, printed media, Training simulation, simulators, videos and video games. These images are either static (i.e. still images) or dynamic (i.e. moving images). CGI both refers to 2D computer graphics and (more frequently) 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and Visual effects, special effects (in films, television programs, commercials, etc.). The application of CGI for creating/improving animations is called ''computer animation'', or ''CGI animation''. History The first feature film to use CGI as well as the composition of live-action film with CGI was ''Vertigo (film), Vertigo'', which used abstract computer graphics by John Whitney (animator), John Whitney in the opening credits of the film. The first feature film to make use of CGI with live action in the storyline of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
