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 A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward th ... (see also pendulum (mathematics)), as well as in the design of electronic elliptic filters. While trigonometry, 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 def ...

Carbon Nanotubes
A scanning tunneling microscopy image of a single-walled carbon nanotube Rotating single-walled zigzag carbon nanotube A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. ''Single-wall carbon nanotubes'' (''SWCNTs'') are one of the allotropes of carbon, intermediate between fullerene cages and flat graphene, with diameters in the range of a nanometre. Although not made this way, single-wall carbon nanotubes can be idealized as cutouts from a two-dimensional hexagonal lattice of carbon atoms rolled up along one of the Bravais lattice vectors of the hexagonal lattice to form a hollow cylinder. In this construction, periodic boundary conditions are imposed over the length of this roll-up vector to yield a helical lattice of seamlessly bonded carbon atoms on the cylinder surface. ''Multi-wall carbon nanotubes'' (''MWCNTs'') consisting of nested single-wall carbon nanotubes weakly bound together by van der Waals interactions in ...

Northern Cyprus
Northern Cyprus ( tr, Kuzey Kıbrıs), officially the Turkish Republic of Northern Cyprus (TRNC; tr, Kuzey Kıbrıs Türk Cumhuriyeti, ''KKTC''), is a '' de facto'' state that comprises the northeastern portion of the island of Cyprus. Recognised only by Turkey, Northern Cyprus is considered by the international community to be part of the Republic of Cyprus. Northern Cyprus extends from the tip of the Karpass Peninsula in the northeast to Morphou Bay, Cape Kormakitis and its westernmost point, the Kokkina exclave in the west. Its southernmost point is the village of Louroujina. A buffer zone under the control of the United Nations stretches between Northern Cyprus and the rest of the island and divides Nicosia, the island's largest city and capital of both sides. A coup d'état in 1974, performed as part of an attempt to annex the island to Greece, prompted the Turkish invasion of Cyprus. This resulted in the eviction of much of the north's Greek Cypriot populat ... [...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 incl ...

Neural Crest
Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm germ layer, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia. After gastrulation, neural crest cells are specified at the border of the neural plate and the non-neural ectoderm. During neurulation, the borders of the neural plate, also known as the neural folds, converge at the dorsal midline to form the neural tube. Subsequently, neural crest cells from the roof plate of the neural tube undergo an epithelial to mesenchymal transition, delaminating from the neuroepithelium and migrating through the periphery where they differentiate into varied cell types. The emergence of neural crest was important in vertebrate evolution because many of its structural derivatives are defining features of the vertebrate clade. Underlying the development of neural crest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netcat
netcat (often abbreviated to nc) is a computer networking utility for reading from and writing to network connections using TCP or UDP. The command is designed to be a dependable back-end that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and investigation tool, since it can produce almost any kind of connection its user could need and has a number of built-in capabilities. Its list of features includes port scanning, transferring files, and port listening: as with any server, it can be used as a backdoor. Features The original netcat's features include: * Outbound or inbound connections, TCP or UDP, to or from any ports * Full DNS forward/reverse checking, with appropriate warnings * Ability to use any local source port * Ability to use any locally configured network source address * Built-in port-scanning capabilities, with randomization * Built-in loose source-routing capability * Can read ...

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 sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Canaan
New Canaan () is a town in Fairfield County, Connecticut, United States. The population was 20,622 according to the 2020 census.

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 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 radiation alters the ...

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 print ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
