Light Beam
A light beam or beam of light is a directional projection of light energy radiating from a light source. Sunlight forms a light beam (a sunbeam) when filtered through media such as clouds, foliage, or windows. To artificially produce a light beam, a lamp and a parabolic reflector is used in many lighting devices such as spotlights, car headlights, PAR Cans, and LED housings. Light from certain types of laser has the smallest possible beam divergence. Visible light beams From the side, a beam of light is only visible if part of the light is scattered by objects: tiny particles like dust, water droplets ( mist, fog, rain), hail, snow, or smoke, or larger objects such as birds. If there are many objects in the light path, then it appears as a continuous beam, but if there are only a few objects, then the light is visible as a few individual bright points. In any case, this scattering of light from a beam, and the resultant visibility of a light beam from the side, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam, Great Torrington
Beam is an historic estate in the parish of Great Torrington, Devon, England. Beam House is situated about 1 1/2 miles north-west and downstream of that town, on the right-bank of the River Torridge. Both the Rolle Canal and the railway crossed the river nearby. It occupies a particularly beautiful setting, described by Lauder (1986) thus: ''"For lovers of rivers and woodland there can be few lovlier settings for a house than this. Steeply wooded banks shelter the valley and the house is situated on slightly higher ground above lush water meadows, almost completely surrounded by the Torridge"'' The estate was a subsidiary seat of the Baron Rolle, Rolle family, lords of the manor of Great Torrington, whose main seat was Stevenstone on the other (south) side of that town and therefore upstream from Beam. It was an outpost of the Royalists during the Civil War. Much of the estate is today owned by Baron Clinton, as heir to the Rolles, but it has had many occupants, including use by ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Beam (horse)
Beam (1924 – 1941) was a British Thoroughbred racehorse and Horse breeding#Terminology, broodmare. As a juvenile she showed promise by winning one race and finishing third in the Molecomb Stakes. In the following year she finished fourth in the 1000 Guineas and won the Haverhill Stakes before beating a strong field to take the Epsom Oaks in a race record time which stood for more than half a century. She was retired from racing at the end of the season. Beam made no impact as a dam of winners and died in 1941 at the age of seventeen. Background Beam was a bay mare bred in the United Kingdom by her owner John Lambton, 3rd Earl of Durham. She was sent into training with Frank Butters at his Fitzroy House stable in Newmarket, Suffolk. She was ridden in most of her races by Tommy Weston (jockey), Tommy Weston. She was one of the best horses sired by Galloper Light, an English-bred stallion who won the Grand Prix de Paris in 1919. Beam was a daughter of Mistrella (foaled 1907), ...

Beam (structure)
A beam is a structural element that primarily resists loads applied laterally across the beam's axis (an element designed to carry a load pushing parallel to its axis would be a strut or column). Its mode of deflection is primarily by bending, as loads produce reaction forces at the beam's support points and internal bending moments, shear, stresses, strains, and deflections. Beams are characterized by their manner of support, profile (shape of cross-section), equilibrium conditions, length, and material. Beams are traditionally descriptions of building or civil engineering structural elements, where the beams are horizontal and carry vertical loads. However, any structure may contain beams, such as automobile frames, aircraft components, machine frames, and other mechanical or structural systems. Any structural element, in any orientation, that primarily resists loads applied laterally across the element's axis is a beam. Overview Historically a beam is a squared ti ...

Apache Beam
Apache Beam is an open source unified programming model to define and execute data processing pipelines, including ETL, batch and stream (continuous) processing. Beam Pipelines are defined using one of the provided SDKs and executed in one of the Beam’s supported ''runners'' (distributed processing back-ends) including Apache Flink, Apache Samza, Apache Spark, and Google Cloud Dataflow. History Apache Beam is one implementation of the Dataflow model paper. The Dataflow model is based on previous work on distributed processing abstractions at Google, in particular on FlumeJava and Millwheel. Google released an open SDK implementation of the Dataflow model in 2014 and an environment to execute Dataflows locally (non-distributed) as well as in the Google Cloud Platform Google Cloud Platform (GCP) is a suite of cloud computing services offered by Google that provides a series of modular cloud services including computing, Computer data storage, data storage, Data analysi ...

Bigelow Expandable Activity Module
The Bigelow Expandable Activity Module (BEAM) is an experimental inflatable space habitat, expandable International Space Station#Pressurised modules, space station module developed by Bigelow Aerospace, under contract to NASA, for testing as a temporary module on the International Space Station (ISS) from 2016 to at most 2028, when the contract can not be further extended. It arrived at the ISS on 10 April 2016, was berthed to the station on 16 April 2016, and was expanded and pressurized on 28 May 2016. Although originally planned to be a two year test, it has exceeded expectations and is used as additional cargo storage. The module is under ownership of NASA after Bigelow Aerospace suspended operations in 2021. History NASA originally considered the idea of inflatable habitats in the 1960s, and developed the TransHab inflatable module concept in the late 1990s. The TransHab project was canceled by Congress in 2000, and Bigelow Aerospace purchased the rights to the patents d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam Search
In computer science, beam search is a heuristic search algorithm that explores a graph by expanding the most promising node in a limited set. Beam search is a modification of best-first search that reduces its memory requirements. Best-first search is a graph search which orders all partial solutions (states) according to some heuristic. But in beam search, only a predetermined number of best partial solutions are kept as candidates. It is thus a greedy algorithm. Details Beam search uses breadth-first search to build its search tree. At each level of the tree, it generates all successors of the states at the current level, sorting them in increasing order of heuristic cost. However, it only stores a predetermined number, \beta, of best states at each level (called the beam width). Only those states are expanded next. The greater the beam width, the fewer states are pruned. With an infinite beam width, no states are pruned and beam search is identical to best-first search. Conve ...

BEAM Robotics
BEAM robotics (from biology, electronics, aesthetics and mechanics) is a style of robotics that primarily uses simple analogue circuits, such as comparators, instead of a microprocessor in order to produce an unusually simple design. While not as flexible as microprocessor based robotics, BEAM robotics can be robust and efficient in performing the task for which it was designed. BEAM robots may use a set of the analog circuits, mimicking biological neurons, to facilitate the robot's response to its working environment. Mechanisms and principles The basic BEAM principles focus on a stimulus-response based ability within a machine. The underlying mechanism was invented by Mark W. Tilden where the circuit (or a Nv net of Nv neurons) is used to simulate biological neuron behaviours. Some similar research was previously done by Ed Rietman in 'Experiments In Artificial Neural Networks'. Tilden's circuit is often compared to a shift register, but with several important features ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BEAM (Erlang Virtual Machine)
BEAM is the virtual machine at the core of the Erlang Open Telecom Platform (OTP). BEAM is part of the Erlang Run-Time System (ERTS), which compiles Erlang source code into bytecode, which is then executed on the BEAM. BEAM bytecode files have the .beam file extension. Originally BEAM was short for ''Bogdan's Erlang Abstract Machine'', named after Bogumil "Bogdan" Hausman, who wrote the original version, but the name may also be referred to as ''Björn's Erlang Abstract Machine'', after Björn Gustavsson, who wrote and maintains the current version. Both developers worked on the system while at Ericsson (), commonly known as Ericsson (), is a Swedish multinational networking and telecommunications company headquartered in Stockholm, Sweden. Ericsson has been a major contributor to the development of the telecommunications industry and is one .... The predecessor of the BEAM was JAM (Joe's Abstract Machine), which was the first virtual machine for the Erlang language and w ...

Robin Hood Energy
Robin Hood Energy was a not-for-profit energy company launched in September 2015 by Nottingham City Council as a competitor to the "big six" energy suppliers in the United Kingdom. The company supplied gas and electricity nationally to homes and businesses until September 2020, when its customer accounts were sold to Centrica, the parent company of British Gas. Structure and operations The company was wholly owned by Nottingham City Council. Its role was to provide low-cost energy to households and address fuel poverty. It offered special tariffs to residents within the boundaries of Nottingham City Council and provided a socially-orientated pricing structure to the whole of the UK. The company operated on a not-for-profit basis by keeping overheads as low as possible, and did not pay bonuses to directors. Any profits made are reinvested. The chair of the company's board was a Nottingham councillor. As a publicly owned energy company, the business aimed to "champion the a ...
