Terminology
Terminology is a group of specialized words and respective meanings in a particular field, and also the study of such terms and their use; the latter meaning is also known as terminology science. A ''term'' is a word, compound word, or multi-word expressions that in specific contexts is given specific meanings—these may deviate from the meanings the same words have in other contexts and in everyday language. Terminology is a discipline that studies, among other things, the development of such terms and their interrelationships within a specialized domain. Terminology differs from lexicography, as it involves the study of concepts, conceptual systems and their labels (''terms''), whereas lexicography studies words and their meanings. Terminology is a discipline that systematically studies the "labelling or designating of concepts" particular to one or more subject fields or domains of human activity. It does this through the research and analysis of terms in context for the pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Term
In mathematical logic, a ground term of a formal system is a term that does not contain any variables. Similarly, a ground formula is a formula that does not contain any variables. In first-order logic with identity, the sentence Q(a) \lor P(b) is a ground formula, with a and b being constant symbols. A ground expression is a ground term or ground formula. Examples Consider the following expressions in first order logic over a signature containing the constant symbols 0 and 1 for the numbers 0 and 1, respectively, a unary function symbol s for the successor function and a binary function symbol + for addition. * s(0), s(s(0)), s(s(s(0))), \ldots are ground terms; * 0 + 1, \; 0 + 1 + 1, \ldots are ground terms; * 0+s(0), \; s(0)+ s(0), \; s(0)+s(s(0))+0 are ground terms; * x + s(1) and s(x) are terms, but not ground terms; * s(0) = 1 and 0 + 0 = 0 are ground formulae. Formal definitions What follows is a formal definition for first-order languages. Let a first-order language b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minterms
In Boolean algebra, any Boolean function can be expressed in the canonical disjunctive normal form ( CDNF) or minterm canonical form and its dual canonical conjunctive normal form ( CCNF) or maxterm canonical form. Other canonical forms include the complete sum of prime implicants or Blake canonical form (and its dual), and the algebraic normal form (also called Zhegalkin or Reed–Muller). ''Minterms'' are called products because they are the logical AND of a set of variables, and ''maxterms'' are called sums because they are the logical OR of a set of variables. These concepts are dual because of their complementary-symmetry relationship as expressed by De Morgan's laws. Two dual canonical forms of ''any'' Boolean function are a "sum of minterms" and a "product of maxterms." The term "Sum of Products" (SoP or SOP) is widely used for the canonical form that is a disjunction (OR) of minterms. Its De Morgan dual is a "Product of Sums" (PoS or POS) for the canonical form that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telecom Enforcement Resource And Monitoring
Telecom Enforcement Resource and Monitoring (TERM), formerly known as Vigilance Telecom Monitoring (VTM), is the vigilance and monitoring wing of the Indian Department of Telecommunications (DoT). TERM is made up of 34 Cells in India's 22 telecom circles and 10 large telecom districts, each headed by a Senior Administrative Grade (SAG) level officer, termed as Deputy Director General (DDG). The main functions of TERM Cells are vigilance, monitoring and security of the network. Apart from this, TERM Cells also operate the Central Monitoring System (CMS), a clandestine mass electronic surveillance program, and carry out other functions. The TERM Cells function as the subordinate offices of the DoT in the field. These Cells represent the Telegraph Authority and the Licensor. History Vigilance Telecom Monitoring Cells (VTM) were created by the Government to control illegal/clandestine telecom operations. Three VTM Cells were set up in October 2004 at Delhi, Mumbai and Hyderabad, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Term Life Insurance
Term life insurance or term assurance is life insurance that provides coverage at a fixed rate of payments for a limited period of time, the relevant term. After that period expires, coverage at the previous rate of premiums is no longer guaranteed and the client must either forgo coverage or potentially obtain further coverage with different payments or conditions. If the life insured dies during the term, the death benefit will be paid to the beneficiary. Term insurance is typically the least expensive way to purchase a substantial death benefit on a coverage amount per premium dollar basis over a specific period of time. Term life insurance can be contrasted to permanent life insurance such as whole life, universal life, and variable universal life, which guarantee coverage at fixed premiums for the lifetime of the covered individual unless the policy is allowed to lapse due to failure to pay premiums. Term insurance is not generally used for estate planning needs or chari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Term (computers)
A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term ''terminal'' covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window. A terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications. These may be running either on the same machine or on a different one via telnet, ssh, dial-up, or over a direct serial connection. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine. Terminals usually support a set of escape sequences for controlling color, cursor position, etc. Examples include the family of terminal control sequence standards known as ECMA-48, ANSI X3.64 or ISO/IEC 642 ...

Term (argumentation)
In argumentation theory, a term is that part of a statement in an argument which refers to a specific thing. Usually, but not always expressed as a noun, one of the requirements to informally prove a conclusion with a deductive argument is for all its terms to be used unambiguously. The ambiguous use of a term in a deductive argument may be an instance of the fallacy of four terms The fallacy of four terms ( la, quaternio terminorum) is the formal fallacy that occurs when a syllogism has four (or more) terms rather than the requisite three, rendering it invalid. Definition Categorical syllogisms always have three terms: : .... Concepts in logic Term logic {{logic-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Term (architecture)
In Classical architecture a term or terminal figure (plural: terms or termini) is a human head and bust that continues as a square tapering pillar-like form. Some may appear similar to a herma. In the architecture and the painted architectural decoration of the European Renaissance and the succeeding Classical styles, term figures are quite common. Often they represent minor deities associated with fields and vineyards and the edges of woodland, Pan and fauns and Bacchantes especially, and they may be draped with garlands of fruit and flowers. Term figures were a particularly characteristic feature of the 16th-century style in furniture and carved interior decoration that is called Antwerp Mannerism Antwerp Mannerism is the name given to the style of a group of largely anonymous painters active in the Southern Netherlands and principally in Antwerp in roughly the first three decades of the 16th century, a movement marking the tail end of Ear ....

Term Symbol
In quantum mechanics Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, ..., the term symbol is an abbreviated description of the (total) angular momentum quantum numbers in a multi-electron atom (however, even a single electron can be described by a term symbol). Each energy level of an atom with a given electron configuration is described by not only the electron configuration but also its own term symbol, as the energy level also depends on the total angular momentum including spin. The usual atomic term symbols assume angular momentum coupling#LS coupling, LS coupling (also known as Henry Norris Russell, Russell–Frederick Albert Saunders, Saunders coupling or spin-orbit coupling). The ground state term symbol is predicted by List of Hund's rules, Hund's rules. The use of the word '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Term Logic
In philosophy, term logic, also known as traditional logic, syllogistic logic or Aristotelian logic, is a loose name for an approach to formal logic that began with Aristotle and was developed further in ancient history mostly by his followers, the Peripatetics. It was revived after the third century CE by Porphyry's Isagoge. Term logic revived in medieval times, first in Islamic logic by Alpharabius in the tenth century, and later in Christian Europe in the twelfth century with the advent of new logic, remaining dominant until the advent of predicate logic in the late nineteenth century. However, even if eclipsed by newer logical systems, term logic still plays a significant role in the study of logic. Rather than radically breaking with term logic, modern logics typically expand it, so to understand the newer systems, one must be acquainted with the earlier one. Aristotle's system Aristotle's logical work is collected in the six texts that are collectively known as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
