Naming Conventions
A naming convention is a convention (generally agreed scheme) for naming things. Conventions differ in their intents, which may include to: * Allow useful information to be deduced from the names based on regularities. For instance, in Manhattan, streets are consecutively numbered; with east–west streets called "Streets" and north–south streets called "Avenues". * Show relationships, and in most personal naming conventions * Ensure that each name is unique for same scope Use cases Well-chosen naming conventions aid the casual user in navigating and searching larger structures. Several areas where naming conventions are commonly used include: * In astronomy, planetary nomenclature * In classics, Roman naming conventions * In computer programming, identifier naming conventions * In computer networking, naming scheme * In humans, naming offspring * In industry, product naming conventions * In the sciences, systematic names for a variety of things Examples Examples of naming c ...

Norton Commander
Norton Commander (NC) is a discontinued prototypical orthodox file manager (OFM), written by John Socha and released by Peter Norton Computing (later acquired in 1990 by the Symantec corporation). NC provides a text-based user interface for managing files on top of MS-DOS. It was officially produced between 1986 and 1998. The last MS-DOS version of Norton Commander, 5.51, was released on July 1, 1998. A related product, ''Norton Desktop'', a graphical shell for MS-DOS and Windows, succeeded Norton Commander. It came in two variants, ''Norton Desktop for DOS'' and ''Norton Desktop for Windows''. Background John Socha started work on Norton Commander in 1984; at the time, he called it "Visual DOS" or "VDOS". Norton Commander was easy to use because it had a constant view of two file manipulation objects at once. After starting the program the user sees two panels with file lists. Each panel can be easily configured to show information about the other panel, a directory tree, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazda MX-5 (NC)
The Mazda MX-5 (NC) is the third generation of the Mazda MX-5 manufactured from 2005 to 2015. At its introduction in 2005, it won the Car of the Year Japan Award and made ''Car and Driver''s 10Best list from 2006 to 2013. The NC is the first MX-5 generation to feature a retractable hardtop variant, with its roof being able to fold and unfold in 12 seconds without sacrificing trunk space. 2006—2008 (NC1) The exterior styling by Yasushi Nakamuta resembled the original design, but unlike the update from NA to NB, which was mostly a nose/tail/interior change, the NC shares no components with the NB, except for the fender-mounted turn signal lights on non-U.S. models, and rear differential internals. The chief designer of this model generation was Moray Callum. The 2003 Mazda Ibuki concept served as a preview of the new model. The suspension changed from a four-wheel double wishbone setup to a front wishbone/rear multilink setup, shared with the Mazda RX-8. Technologies includi ...

Numerical Control
Numerical control (also computer numerical control, and commonly called CNC) is the automated control of machining tools (such as drills, lathes, mills, grinders, routers and 3D printers) by means of a computer. A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following coded programmed instructions and without a manual operator directly controlling the machining operation. A CNC machine is a motorized maneuverable tool and often a motorized maneuverable platform, which are both controlled by a computer, according to specific input instructions. Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions such as G-code and M-code, and then executed. The program can be written by a person or, far more often, generated by graphical computer-aided design (CAD) or computer-aided manufacturing (CAM) software. In the case of 3D printers, the part to be printed is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normally Closed
In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching current can pass between them, while when the contacts are separated no current can flow. Switches are made in many different configurations; they may have multiple sets of contacts controlled by the same knob or actuator, and the contacts may operate simultaneously, sequentially, or alternately. A switch may be operated manually, for example, a light switch or a keyboard button, or may function as a sensing element to sense the position of a machine part, liquid level, pressure, or temperature, such as a thermostat. Many specialized forms exist, such as the toggle switch, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noun Class
In linguistics, a noun class is a particular category of nouns. A noun may belong to a given class because of the characteristic features of its referent, such as gender, animacy, shape, but such designations are often clearly conventional. Some authors use the term "grammatical gender" as a synonym of "noun class", but others consider these different concepts. Noun classes should not be confused with noun classifiers. Notion There are three main ways by which natural languages categorize nouns into noun classes: * according to similarities in their meaning (semantic criterion); * by grouping them with other nouns that have similar form (morphology); * through an arbitrary convention. Usually, a combination of the three types of criteria is used, though one is more prevalent. Noun classes form a system of grammatical agreement. A noun in a given class may require: * agreement affixes on adjectives, pronouns, numerals, etc. in the same noun phrase, * agreement affixes on the ve ...

Noise Curve
Noise curves are a common way to characterise background noise in unoccupied buildings and spaces. Their purpose is to produce a single-value representation of a complete sound spectrum. International standards organizations (ISO, ANSI and ASA ASA as an abbreviation or initialism may refer to: Biology and medicine * Accessible surface area of a biomolecule, accessible to a solvent * Acetylsalicylic acid, aspirin * Advanced surface ablation, refractive eye surgery * Anterior spinal ar ...) recognize the need to objectify judgements on the amount of ambient noise in enclosed spaces, and provide us with definitions for various noise curves. The ANSI/ASA S12.2-2008 standard, for example, recommends an NC value of 25-35 for schools and 15-18 for concert halls. Background noise may have several undesirable effects. Noise can be an annoyance that creates fatigue and negatively affects productivity, safety and the ability to communicate. Therefore, standard methodologies for quantifyi ...

National Radio Company
The National Radio Company, headquartered in Malden, Massachusetts, United States, was an American manufacturer of radio equipment from 1914 to 1991. History The company was incorporated, in 1914, as the "National Toy Company", but by 1916 had included household appliances in their product range. This expansion led to the name change to the "National Company, Inc.". By 1923 the product line included toys, food mixers, and radio components. Radio components were to play an important part in the company's growth in the mid-1920s as they moved into the large scale manufacture of capacitors. It was at this time that two engineers from Harvard University, Fred H. Drake and Glen Browning, approached National to manufacture components to their specifications for a radio receiver of their own design. This relationship led to the production and sale of the "National Regenaformer" kit for home construction of the Browning-Drake design. The set was capable of tuning the standard AM broadcast ...

National Coarse
The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. It has the same 60° profile as the ISO metric screw thread, but the characteristic dimensions of each UTS thread (outer diameter and pitch) were chosen as an inch fraction rather than a millimeter value. The UTS is currently controlled by ASME/ANSI in the United States. Origins : ''See the "History of standardization" section of the screw thread article.'' Basic profile Each thread in the series is characterized by its major diameter ''D''maj and its pitch, ''P''. UTS threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The outermost and the innermost of the height ''H'' of the V-shap ...

Nc (elliptic Function)
In mathematics, the Jacobi elliptic functions are a set of basic elliptic functions. They are found in the description of the motion of a pendulum (see also pendulum (mathematics)), as well as in the design of electronic elliptic filters. While trigonometric functions are defined with reference to a circle, the Jacobi elliptic functions are a generalization which refer to other conic sections, the ellipse in particular. The relation to trigonometric functions is contained in the notation, for example, by the matching notation \operatorname for \sin. The Jacobi elliptic functions are used more often in practical problems than the Weierstrass elliptic functions as they do not require notions of complex analysis to be defined and/or understood. They were introduced by . Carl Friedrich Gauss had already studied special Jacobi elliptic functions in 1797, the lemniscate elliptic functions in particular, but his work was published much later. Overview There are twelve Jacobi elliptic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Chemistry
Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. It is the chemistry of radioactive elements such as the actinides, radium and radon together with the chemistry associated with equipment (such as nuclear reactors) which are designed to perform nuclear processes. This includes the corrosion of surfaces and the behavior under conditions of both normal and abnormal operation (such as during an nuclear accidents, accident). An important area is the behavior of objects and materials after being placed into a nuclear waste storage or disposal site. It includes the study of the chemical effects resulting from the absorption of radiation within living animals, plants, and other materials. The radiation chemistry controls much of radiation biology as radiation has an effect on living things at the molecular scale. To explain it another way, the rad ...
