Bidirectional LSTM
Bidirectional may refer to: * Bidirectional, a roadway that carries traffic moving in opposite directions * Bi-directional vehicle, a tram or train or any other vehicle that can be controlled from either end and can move forward or backward with equal ease without any need to be turned around * Bidirectional text, text containing text in both text directionalities * Duplex (telecommunications), communication in both directions * Bidirectionalization, a process in computer science * Bidirectional railway signalling; see Application of railway signals#Bidirectional signalling * Bidirectional learning/process refers to two way learning. In terms of socialization, the process helps both novices and experts learn from each other. * Bidirectional LED A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roadway
A carriageway (British English) or roadway (North American English) consists of a width of road on which a vehicle is not restricted by any physical barriers or separation to move lateral movement, laterally. A carriageway generally consists of a number of lane, traffic lanes together with any associated shoulder (road), shoulder, but may be a sole lane in width (for example, a highway Interchange (road), offramp). Description A single carriageway road (North American English: undivided highway) has one carriageway with 1, 2 or more lanes together with any associated sidewalk, footways (North American English: sidewalk) and road verges (North American English: tree belt). A dual carriageway road (North American English: divided highway) has two roadways separated by a central reservation (North American English: median). A local-express lanes, local-express lane system (also called collector-express or collector-distributor) has more than two roadways, typically two sets of 'loc ...

Bi-directional Vehicle
A bi-directional vehicle is a vehicle that can be driven in either direction, forwards or backwards. Usually, the term refers to rail vehicles, such as trains or trams, and some airside transfer buses, that are equipped with driver's cabs at both ends. These vehicles generally have entry and exit doors on either side of the vehicle. One major benefit of bi-directional vehicles is the ability to reverse direction at a terminal station with a stub-end track. On a system using double track, a crossover switch is often used to move the vehicle to the other track. This situation contrasts with the use of uni-directional vehicles, which requires the use of a balloon loop, triangle junction, or turntable A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogu ... to reverse direction.

Bidirectional Text
A bidirectional text contains two text directionalities, right-to-left (RTL) and left-to-right (LTR). It generally involves text containing different types of alphabets, but may also refer to boustrophedon, which is changing text direction in each row. Many computer programs fail to display bidirectional text correctly. For example, this page is mostly LTR English script, and here is the RTL Hebrew name Sarah: spelled sin on the right, resh , and heh on the left. Some so-called right-to-left script such as the Persian script (and Arabic) are mostly but not exclusively right-to-left; mathematical expressions, numeric dates and numbers bearing units are embedded from left to right. That also happens if e.g. English is embedded in them, or vice versa, if Arabic, Persian or Hebrew is embedded in a left-to-right script. Bidirectional script support Bidirectional script support is the capability of a computer system to correctly display bidirectional text. The term is often sh ...

Duplex (telecommunications)
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment of equipment in the field. There are two types of duplex communication systems: full-duplex (FDX) and half-duplex (HDX). In a full-duplex system, both parties can communicate with each other simultaneously. An example of a full-duplex device is plain old telephone service; the parties at both ends of a call can speak and be heard by the other party simultaneously. The earphone reproduces the speech of the remote party as the microphone transmits the speech of the local party. There is a two-way communication channel between them, or more strictly speaking, there are two communication chann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bidirectionalization
In computer science, bidirectionalization refers to the process of given a source-to-view transformation (automatically) finding a mapping from the original source and an updated view to an updated source. See also * Bidirectional transformation * Inverse function * Reversible computing * View (database) In a database, a view is the result set of a ''stored'' query on the data, which the database users can query just as they would in a persistent database collection object. This pre-established query command is kept in the database dictionary. Un ... Further reading * Janis Voigtländer, Zhenjiang Hu, Kazutaka Matsuda, and Meng Wang.

Application Of Railway Signals
The application of railway signals on a rail layout is determined by various factors, principally the location of points of potential conflict, as well as the speed and frequency of trains and the movements they require to make. Non-provision of signals Before discussing the application of signals, it is useful to highlight some situations where signals are ''not'' required: * Sidings generally need not be signalled, as all movements within them are made cautiously at low speed. * Tram lines frequently employ "running on sight" without any signals (similar to road traffic). * Where movement authorities are passed to drivers exclusively by means other than fixed signals (e.g. by written or verbal authority), token, or cab signalling. Purpose of signals Signals exist primarily to pass instructions and information to drivers of passing trains. The driver interprets the signal's indication and acts accordingly. The most important indication is 'danger', which means 'stop'. No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
