North Carolina
North Carolina () is a state in the Southeastern region of the United States. The state is the 28th largest and 9th-most populous of the United States. It is bordered by Virginia to the north, the Atlantic Ocean to the east, Georgia and South Carolina to the south, and Tennessee to the west. In the 2020 census, the state had a population of 10,439,388. Raleigh is the state's capital and Charlotte is its largest city.

NC (complexity)
In computational complexity theory, the class NC (for "Nick's Class") is the set of decision problems decidable in polylogarithmic time on a parallel computer with a polynomial number of processors. In other words, a problem with input size ''n'' is in NC if there exist constants ''c'' and ''k'' such that it can be solved in time using parallel processors. Stephen Cook coined the name "Nick's class" after Nick Pippenger, who had done extensive research on circuits with polylogarithmic depth and polynomial size.Arora & Barak (2009) p.120 Just as the class P can be thought of as the tractable problems ( Cobham's thesis), so NC can be thought of as the problems that can be efficiently solved on a parallel computer.Arora & Barak (2009) p.118 NC is a subset of P because polylogarithmic parallel computations can be simulated by polynomial-time sequential ones. It is unknown whether NC = P, but most researchers suspect this to be false, meaning that there are probably some tractable pr ...

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] |
Network Computer
The Network Computer (or NC) was a diskless desktop computer device made by Oracle Corporation from about 1996 to 2000. The devices were designed and manufactured by an alliance, which included Sun Microsystems, IBM, and others. The devices were designed with minimum specifications, based on the Network Computer Reference Profile. The brand was also employed as a marketing term to try to popularize this design of computer within enterprise and among consumers. The NC brand was mainly intended to inspire a range of desktop computers from various suppliers that, by virtue of their diskless design and use of inexpensive components and software, were cheaper and easier to manage than standard fat client desktops. However, due to the commoditization of standard desktop components, and due to the increasing availability and popularity of various software options for using full desktops as diskless nodes, thin clients, and hybrid clients, the Network Computer brand never achieved t ...

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 Geography of Cyprus, island of Cyprus. List of states with limited recognition, Recognised only by Turkey, Northern Cyprus is considered by the international community to be part of the Cyprus, Republic of Cyprus. Northern Cyprus extends from Cape Apostolos Andreas, 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 United Nations Buffer Zone in Cyprus, 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.

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 ...

Isocyanide
An isocyanide (also called isonitrile or carbylamine) is an organic compound with the functional group –. It is the isomer of the related nitrile (–C≡N), hence the prefix is ''isocyano''.IUPAC Goldboo''isocyanides''/ref> The organic fragment is connected to the isocyanide group through the nitrogen atom, not via the carbon. They are used as building blocks for the synthesis of other compounds. Properties Structure and bonding The C-N distance in isocyanides is 115.8 pm in methyl isocyanide. The C-N-C angles are near 180°. Akin to carbon monoxide, isocyanides are described by two resonance structures, one with a triple bond between the nitrogen and the carbon and one with a double bond between. The π lone pair of the nitrogen stabilizes the structure and is responsible of the linearity of isocyanides, although the reactivity of isocyanides reflects some carbene character, at least in a formal sense. Thus, both resonance structures are useful representations. They are sus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
