Bypass (road)
A bypass is a road or highway that avoids or "bypasses" a built-up area, town, or village, to let through traffic flow without interference from local traffic, to reduce Traffic congestion, congestion in the built-up area, to improve road safety and as replacement for obsolete roads that are no longer in use as a result of devastating natural disasters (earthquakes, tsunamis, landslides, volcanic eruptions). A bypass specifically designated for trucks may be called a truck route. If there are no strong land use controls, buildings are often built in town along a bypass, converting it into an ordinary town road, and the bypass may eventually become as congested as the local streets it was intended to avoid. Many businesses are often built there for ease of access, while homes are often avoided for noise and pollution reasons. Bypass routes are often on new land where no road originally existed. This creates a conflict between those who support a bypass to reduce congestion in a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

By-pass Variegated
By-pass Variegated is a term coined by the cartoonist and architectural historian Osbert Lancaster in his 1938 book '' Pillar to Post''. It represents the ribbon development of houses in Britain in the 1920s and 1930s, in a mish-mash of architectural styles. Style Before 1947 there was no systematic legal control of property development in Britain: landowners could in general build as they wished on their land. Between the First and Second World Wars speculative builders bought large tracts of land alongside new arterial roads and built mile after mile of mostly semi-detached, and some detached, houses. They were built as cheaply as possible, allowing people with modest incomes to buy a home for the first time, rather than rent. In the inter-war period owner-occupation in Britain rose from 10 to 32 per cent. In a 2010 study of Britain in the 1930s, Juliet Gardiner gives an example of a working-class couple buying a new house of this kind in Hornchurch, Essex for £495. In Lancas ...

Railroad Bypass
A railroad (or railway) cutoff (or cut-off) is a new railroad line built to replace or supplement an existing route, typically one where the old line is deficient for some reason. Reasons and types The term "cutoff" refers to the fact that the new line ''cuts off'' distance (and/or time) and is, therefore, shorter distance-wise (or time-wise) than the old line. This is often the case, although the primary reason for building the cutoff may be to create a line with a better gradient profile, or other desirable features usually related to efficiency of operation that are lacking in the old line rather than merely shortening the distance between two endpoints. Bypassing a congested area, such as a city or railroad station, or a section of track with an already-existing high volume, is an additional reason to construct a new line. The building of a high-speed line to replace a lower-speed line is another possibility; one example of this is the New Lower Inn Valley railway in Austr ...

The Bypass
''The Bypass'' is a 2003 Indian-British short silent crime film written and directed by Amit Kumar starring Nawazuddin Siddiqui, Irfan Khan and Sundar Dan Detha. The Bypass was filmed on a stranded road somewhere in Rajasthan, India. The film was shown at the Edinburgh International Film Festival and Aubagne Film Festival. Plot The film is about two friends who stay by the stranded road "Bypass" and a corrupt police officer. The two friends frequently mug and ultimately kill the people who travel by the road. Amit Kumar starts the film by showing a couple traveling by the road, and then Nawazuddin Siddiqui stops the car by throwing a rock. The two friends then steal money and graphically kill the pair. Irrfan Khan's role as a corrupt police officer is established when he takes a watch by cutting the wrist of a dead man, then rapes a lady and tries to kill the two muggers for the money they had. The director represents the thrill of "Bypass" through violence and aggression. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diving Rebreather
A Diving rebreather is an underwater breathing apparatus that absorbs the carbon dioxide of a diver's breathing, exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the diver. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, and, for covert military use by frogmen or observation of underwater life, to eliminate the bubbles produced by an open circuit system. A diving rebreather is generally understood to be a portable unit carried by the user, and is therefore a type of self-contained underwater breathing apparatus (scuba). A semi-closed rebreather carried by the diver may also be known as a gas extender. The same technology on a submersible, underwater habitat, or surface installation ...

Blowoff Valve
A blowoff valve (also called dump valve or compressor bypass valve) is a pressure release system present in most petrol turbocharged engines. Blowoff valves are used to reduce pressure in the intake system as the throttle is closed, thus preventing compressor surge. Design A key function of blowoff valves is to prevent compressor surge, a phenomenon that would otherwise occur as the throttle is closed in a turbocharged engine. If the turbocharger's compressor wheel is spinning at high speed when the throttle is suddenly closed (such as during a gear change), the flow reduces beyond the surge line of the compressor. At this point the change in pressure across the compressor reduces, leading to a collapse in flow and possibly even flow reversal and a collapse in plenum pressure. As the compressor is still spinning at high speed, once the flow has reduced sufficiently, the change in pressure across the compressor begins to rise and flow is re-established into the plenum. This rap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bypass Tube
This article briefly describes the components and systems found in jet engines. Major components Major components of a turbojet including references to turbofans, turboprops and turboshafts: *Cold section: **Air intake (inlet) — For subsonic aircraft, the inlet is a duct which is required to ensure smooth airflow into the engine despite air approaching the inlet from directions other than straight ahead. This occurs on the ground from cross winds and in flight with aircraft pitch and yaw motions. The duct length is minimised to reduce drag and weight. Air enters the compressor at about half the speed of sound so at flight speeds lower than this the flow will accelerate along the inlet and at higher flight speeds it will slow down. Thus the internal profile of the inlet has to accommodate both accelerating and diffusing flow without undue losses. For supersonic aircraft, the inlet has features such as cones and ramps to produce the most efficient series of shockwaves which for ...

Bypass Switch
A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc. Active, in-line security appliances are single points of failure in live computer networks because if the appliance loses power, experiences a software failure, or is taken off-line for updates or upgrades, traffic can no longer flow through the critical link. The bypass switch or bypass tap removes this point of failure by automatically 'switching traffic via bypass mode' to keep the critical network link up. A bypass switch has four ports. Two network ports create an in-line connection in the network link that is to be monitored. This connection is fully passive; if the bypass switch itself loses power, traffic continues to flow unimpeded through the link. Two monitor ports are used to connect the in-line monitoring appliance. During normal operation, the bypass switc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Bypass
A flood bypass is a region of land or a large man-made structure that is designed to convey excess flood waters from a river or stream in order to reduce the risk of flooding on the natural river or stream near a key point of interest, such as a city. Flood bypasses, sometimes called ''floodways'', often have man-made diversion works, such as diversion weirs and spillways, at their head or point of origin. The main body of a flood bypass is often a natural flood plain. Many flood bypasses are designed to carry enough water such that combined flows down the original river or stream and flood bypass will not exceed the expected maximum flood flow of the river or stream. Flood bypasses are typically used only during major floods and act in a similar nature to a detention basin. Since the area of a flood bypass is significantly larger than the cross-sectional area of the original river or stream channel from which water is diverted, the velocity of water in a flood bypass will be ...

Bypass Duct
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more jet thrust relative t ...
