LS 90
{{Short description, Czech and Slovak railway signalling system LS (abbreviation of ''liniový systém'' in Czech, literally 'line system', also translated as 'continuous system') is a cab signalling and train protection system used on the main lines of Czech and Slovak railways (mandatory on all lines where track speed exceeds 100 km/h in the Czech republic or 120 km/h in Slovakia). This system continuously transmits and shows a signal aspect of the next main signal in the driver's cabin while also periodically checking the driver's vigilance when their attention is required (e.g. a speed reduction). The on-board part of the system has two main functions: showing the next signal and checking the driver's vigilance. The signal aspect is shown on a dedicated panel in the driver's cabin, usually one of 4 lights (yellow, red, green, yellow annulus), corresponding to the four signal aspects. The panel also includes a blue light, indicating that driver's attention is not requ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chevrolet
Chevrolet ( ) is an American automobile division of the manufacturer General Motors (GM). In North America, Chevrolet produces and sells a wide range of vehicles, from subcompact automobiles to medium-duty commercial trucks. Due to the prominence and name recognition of Chevrolet as one of General Motors' global marques, "Chevrolet" or its affectionate nickname 'Chevy' or is used at times as a synonym for General Motors or its products, one example being the GM LS1 engine, commonly known by the name or a variant thereof of its progenitor, the Chevrolet small-block engine. Louis Chevrolet (1878–1941), Arthur Chevrolet (1884–1946) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angular Momentum Coupling
In quantum mechanics, angular momentum coupling is the procedure of constructing eigenstates of total angular momentum out of eigenstates of separate angular momenta. For instance, the orbit and spin of a single particle can interact through spin–orbit interaction, in which case the complete physical picture must include spin–orbit coupling. Or two charged particles, each with a well-defined angular momentum, may interact by Electrostatic#Coulomb's law, Coulomb forces, in which case coupling of the two one-particle angular momenta to a total angular momentum is a useful step in the solution of the two-particle Schrödinger equation. In both cases the separate angular momenta are no longer constants of motion, but the sum of the two angular momenta usually still is. Angular momentum coupling in atoms is of importance in atomic spectroscopy. Angular momentum coupling of electron spins is of importance in quantum chemistry. Also in the nuclear shell model angular momentum co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Löwenheim–Skolem Theorem
In mathematical logic, the Löwenheim–Skolem theorem is a theorem on the existence and cardinality of models, named after Leopold Löwenheim and Thoralf Skolem. The precise formulation is given below. It implies that if a countable first-order theory has an infinite model, then for every infinite cardinal number ''κ'' it has a model of size ''κ'', and that no first-order theory with an infinite model can have a unique model up to isomorphism. As a consequence, first-order theories are unable to control the cardinality of their infinite models. The (downward) Löwenheim–Skolem theorem is one of the two key properties, along with the compactness theorem, that are used in Lindström's theorem to characterize first-order logic. In general, the Löwenheim–Skolem theorem does not hold in stronger logics such as second-order logic. Theorem In its general form, the Löwenheim–Skolem Theorem states that for every signature ''σ'', every infinite ''σ''-structure ''M'' ...

Least Squares
The method of least squares is a mathematical optimization technique that aims to determine the best fit function by minimizing the sum of the squares of the differences between the observed values and the predicted values of the model. The method is widely used in areas such as regression analysis, curve fitting and data modeling. The least squares method can be categorized into linear and nonlinear forms, depending on the relationship between the model parameters and the observed data. The method was first proposed by Adrien-Marie Legendre in 1805 and further developed by Carl Friedrich Gauss. History Founding The method of least squares grew out of the fields of astronomy and geodesy, as scientists and mathematicians sought to provide solutions to the challenges of navigating the Earth's oceans during the Age of Discovery. The accurate description of the behavior of celestial bodies was the key to enabling ships to sail in open seas, where sailors could no longer rely on la ...

Land Surveyor
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designated positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. A professional in land surveying is called a land surveyor. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, lidar sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface loc ...

7400 Series
The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated circuits (ICs). In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package. A low-cost plastic package SN7400 series was introduced in 1966 which quickly gained over 50% of the logic chip market, and eventually becoming ''de facto'' standardized electronic components. Since the introduction of the original bipolar-transistor TTL parts, Pin-compatibility, pin-compatible parts were introduced with such features as low power CMOS technology and LVCMOS, lower supply voltages. Surface-mount technology, Surface mount packages exist for several popular logic family functions. Overview The 7400 series contains hundreds of devices that provide everything from basic logic gates, flip-flop (electronics), flip-flops, and counters, to special purpose bus transceivers and arithmetic logic units (ALU). Specific functions are described in a list of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Link-state Routing Protocol
Link-state routing protocols are one of the two main classes of routing protocols used in packet switching networks for computer communications, the others being distance-vector routing protocols. Examples of link-state routing protocols include Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). The link-state protocol is performed by every ''switching node'' in the network (i.e., nodes which are prepared to forward packets; in the Internet, these are called Router (computing), routers). The basic concept of link-state routing is that every node constructs a ''map'' of the connectivity to the network in the form of a graph theory, graph, showing which nodes are connected to which other nodes. Each node then independently calculates the next best logical ''path'' from it to every possible destination in the network. Each collection of best paths will then form each node's routing table. This contrasts with distance-vector routing protocols, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
