MI 2N
The MI 2N (French: ''Matériel d'Interconnexion à 2 Niveaux'', English: ''two-level interconnection rolling stock'') is a family of double-deck, dual-voltage electric multiple unit trainsets that are operated on the Réseau Express Régional (RER), a hybrid suburban commuter and rapid transit system serving Paris and its Île-de-France suburbs. There are two variants of the MI 2N that look very similar but feature different motorization and interior layout: * The MI 2N "Altéo" is operated by RATP on the RER A line. 43 trains or 215 cars were built. * The Class Z 22500 (MI 2N "Eole") is operated by SNCF on the RER E line. 53 trains or 265 cars were built. The trainsets were by a consortium of French manufacturer Alstom (at the time known as GEC Alstom) and Canadian conglomerate Bombardier. The final assembly of the trains was performed at Alstom's Valenciennes factory and Bombardier's Crespin factory between 1995 and 2005. The double-decker trains grew out of an effo ...

JEDEC
The JEDEC Solid State Technology Association is an independent semiconductor engineering trade organization and standardization body headquartered in Arlington County, Virginia, United States. JEDEC has over 300 members, including some of the world's largest computer companies. Its scope and past activities includes standardization of part numbers, defining an electrostatic discharge (ESD) standard, and leadership in the lead-free manufacturing transition. The origin of JEDEC traces back to 1944, when RMA (subsequently renamed EIA) and NEMA established the Joint Electron Tube Engineering Council (JETEC) to coordinate vacuum tube type numberings. In 1958, with the advent of semiconductor technology, the joint JETEC-activity of EIA and NEMA was renamed into Joint Electron Device Engineering Council. NEMA discontinued its involvement in 1979. In the fall of 1999, JEDEC became a separate trade association under the current name, but maintained an EIA alliance, until EIA ceased o ...

2N2222
The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture. The 2N2222 is considered a very common transistor, and is used as an exemplar of an NPN transistor. It is frequently used as a small-signal transistor, and it remains a small general purpose transistor of enduring popularity. The 2N2222 was part of a family of devices described by Motorola at a 1962 IRE convention. Since then it has been made by many semiconductor companies, for example, Texas Instruments.''The Transistor and Diode Data Book for Design Engineers'', Texas Instruments Incorporated, no date, TI publication number CC413 71242-73-CSS, page 4-93 Specifications The JEDEC registration of a device number ensures particular rated values will be met by all p ...

Uninterruptible Power Supply
An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or flywheels. The on-battery run-time of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment. It is a type of continual power system. A UPS is typically used to protect hardware such as computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from ones designed to protect a single computer without a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powers Of 2
A power of two is a number of the form where is an integer, that is, the result of exponentiation with number two as the base and integer as the exponent. In a context where only integers are considered, is restricted to non-negative values, so there are 1, 2, and 2 multiplied by itself a certain number of times. The first ten powers of 2 for non-negative values of are: : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, ... Because two is the base of the binary numeral system, powers of two are common in computer science. Written in binary, a power of two always has the form 100...000 or 0.00...001, just like a power of 10 in the decimal system. Computer science Two to the exponent of , written as , is the number of ways the bits in a binary word of length can be arranged. A word, interpreted as an unsigned integer, can represent values from 0 () to () inclusively. Corresponding signed integer values can be positive, negative and zero; see signed numbe ...

Ploidy
Ploidy () is the number of complete sets of chromosomes in a cell (biology), cell, and hence the number of possible alleles for Autosome, autosomal and Pseudoautosomal region, pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, Tissue (biology), tissues, and Individual#Biology, individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploidy, polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexual reproduction, sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different or ...

New Jersey Route 17
Route 17 is a state highway in Bergen County, New Jersey, United States, that provides a major route from the George Washington Bridge, Lincoln Tunnel and other northeast New Jersey points to the New York State Thruway at Suffern, New York. It runs from an intersection with Route 7 and County Route 507 (CR 507) in North Arlington north to the New York border along Interstate 287 (I-287) in Mahwah, where New York State Route 17 (NY 17) continues into New York. Between Route 7 and Route 3 in Rutherford, Route 17 serves as a local road. From Route 3 north to the junction with U.S. Route 46 (US 46) in Hasbrouck Heights, the road is a suburban arterial with jughandles. The portion of Route 17 from US 46 to I-287 near the state line in Mahwah is a limited-access road with all cross traffic handled by interchanges, and many driveways and side streets accessed from right-in/right-out ramps from the right lan ...

RER A
RER A is one of the five lines in the Réseau Express Régional (English: Regional Express Network), a hybrid commuter rail and rapid transit system serving Paris, France and its suburbs. The line crosses the region from east to west, with all trains serving a group of stations in central Paris, before branching out towards the ends of the line. The initial portion of the line was built in stages between December 1969 and December 1977 by connecting two existing suburban commuter rail lines with a new tunnel under Paris: the line between Vincennes and Boissy-Saint-Léger in the east (which formerly terminated at the now-closed Gare de la Bastille), and the line between Saint-Germain-en-Laye and Nanterre line in the west (which formerly used a surface alignment to Paris Saint-Lazare which is still in use as Transilien L). The viaduct between Vincennes and the former Gare de la Bastille terminus was redeveloped into the Promenade plantée elevated park in 1993. Since opening, th ...

HP 2N
ISO/IEC 8859-2:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 2: Latin alphabet No. 2'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as "Latin-2". It is generally intended for Central or "Eastern European" languages that are written in the Latin script. Note that ISO/IEC 8859-2 is very different from code page 852 (MS-DOS Latin 2, PC Latin 2) which is also referred to as "Latin-2" in Czech and Slovak regions. Code page 912 is an extension. Almost half the use of the encoding is for Polish, and it's the main legacy encoding for Polish, while virtually all use of it has been replaced by UTF-8 (on the web). ISO-8859-2 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. Less than 0.04% of all web pages use ISO-8859-2 as of October 2022. Microsoft has assigned code page 28 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
