Turbine engines are light and, particularly when used on aircraft, efficient.[citation needed] On the other hand, they cost more and require careful maintenance. They can also be damaged by ingesting foreign objects, and they produce a hot exhaust. Trains using turbines are called gas turbine-electric locomotives. Examples of surface vehicles using turbines are M1 Abrams, MTT Turbine SUPERBIKE and the Millennium. Pulse jet engines are similar in many ways to turbojets, but have almost no moving parts. For this reason, they were very appealing to vehicle designers in the past; however their noise, heat and inefficiency has led to their abandonment. A historical example of the use of a pulse jet was the V-1 flying bomb. Pulse jets are still occasionally used in amateur experiments. With the advent of modern technology, the pulse detonation engine has become practical and was successfully tested on a Rutan VariEze. While the pulse detonation engine is much more efficient than the pulse jet and even turbine engines, it still suffers from extreme noise and vibration levels. Ramjets also have few moving parts, but they only work at high speed, so that their use is restricted to tip jet helicopters and high speed aircraft such as the Lockheed SR-71 Blackbird. Rocket engines are primarily used on rockets, rocket sleds and experimental aircraft. Rocket engines are extremely powerful. The heaviest vehicle ever to leave the ground, the Saturn V rocket, was powered by five F-1 rocket engines generating a combined 180 million horsepower (134.2 gigawatt). Rocket engines also have no need to "push off" anything, a fact that the New York Times denied in error. Rocket engines can be particularly simple, sometimes consisting of nothing more than a catalyst, as in the case of a hydrogen peroxide rocket. This makes them an attractive option for vehicles such as jet packs. Despite their simplicity, rocket engines are often dangerous and susceptible to explosions. The fuel they run off may be flammable, poisonous, corrosive or cryogenic. They also suffer from poor efficiency. For these reasons, rocket engines are only used when absolutely necessary.[citation needed] Electric motors are used in electric vehicles such as electric bicycles, electric scooters, small boats, subways, trains, trolleybuses, trams and experimental aircraft. Electric motors can be very efficient: over 90% efficiency is common. Electric motors can also be built to be powerful, reliable, low-maintenance and of any size. Electric motors can deliver a range of speeds and torques without necessarily using a gearbox (although it may be more economical to use one). Electric motors are limited in their use chiefly by the difficulty of supplying electricity.[citation needed] Compressed gas motors have been used on some vehicles experimentally. They are simple, efficient, safe, cheap, reliable and operate in a variety of conditions. One of the difficulties met when using gas motors is the cooling effect of expanding gas. These engines are limited by how quickly they absorb heat from their surroundings. The cooling effect can, however, double as air conditioning. Compressed gas motors also lose effectiveness with falling gas pressure. Ion thrusters are used on some satellites and spacecraft. They are only effective in a vacuum, which limits their use to spaceborne vehicles. Ion thrusters run primarily off electricity, but they also need a propellant such as caesium, or more recently xenon. Ion thrusters can achieve extremely high speeds and use little propellant; however they are power-hungry ------------------------------ Date: Fri, 21 Aug 2020 08:58:09 -0400 From: "Health Alert" Subject: Foods To Eat If You Have Arthritis Foods To Eat If You Have Arthritis http://observical.buzz/nxen72W2M-v8pLj8EUUwXhfH27sCBhkKw6P4fPPImIMA7WdQ http://observical.buzz/WoKc5co5Eg7C1diFbTTfYms4hsldeNRdDdYtwdLrtx3yXRzP Continuous track is sometimes used instead of wheels to power land vehicles. Continuous track has the advantages of a larger contact area, easy repairs on small damage, and high maneuverability. Examples of vehicles using continuous track are tanks, snowmobiles and excavators. Two continuous tracks used together allow for steering. The largest vehicle in the world, the Bagger 288, is propelled by continuous tracks. Propellers (as well as screws, fans and rotors) are used to move through a fluid. Propellers have been used as toys since ancient times, however it was Leonardo da Vinci who devised what was one of the earliest propeller driven vehicles, the "aerial-screw". In 1661, Toogood & Hays adopted the screw for use as a ship propeller. Since then, the propeller has been tested on many terrestrial vehicles, including the Schienenzeppelin train and numerous cars. In modern times, propellers are most prevalent on watercraft and aircraft, as well as some amphibious vehicles such as hovercraft and ground-effect vehicles. Intuitively, propellers cannot work in space as there is no working fluid, however some sources have suggested that since space is never empty, a propeller could be made to work in space. Similarly to propeller vehicles, some vehicles use wings for propulsion. Sailboats and sailplanes are propelled by the forward component of lift generated by their sails/wings. Ornithopters also produce thrust aerodynamically. Ornithopters with large rounded leading edges produce lift by leading-edge suction forces. Paddle wheels are used on some older watercraft and their reconstructions. These ships were known as paddle steamers. Because paddle wheels simply push against the water, their design and construction is very simple. The oldest such ship in scheduled service is the Skibladner. Many pedalo boats also use paddle wheels for propulsion. Screw-propelled vehicles are propelled by auger-like cylinders fitted with helical flanges. Because they can produce thrust on both land and water, they are commonly used on all-terrain vehicles. The ZiL-2906 was a Soviet-designed screw-propelled vehicle designed to retrieve cosmonauts from the Siberian wilderness. Friction All or almost all of the useful energy produced by the engine is usually dissipated as friction; so minimising frictional losses is very important in many vehicles. The main sources of friction are rolling friction and fluid drag (air drag or water drag). Wheels have low bearing friction and pneumatic tyres give low rolling friction. Steel wheels on steel tracks are lower still. Aerodynamic drag can be reduced by streamlined design features. Friction is desirable and important in supplying traction to facilitate motion on land. Most land vehicles rely on friction for accelerating, decelerating and changing direction. Sudden reductions in traction can cause loss of control and accidents. ------------------------------ Date: Fri, 21 Aug 2020 08:33:08 -0400 From: "Peak Bioboost" Subject: Add THIS to coffee or tea to eliminate constipation Add THIS to coffee or tea to eliminate constipation http://fostrage.cyou/USTd--WBHWZflpCbwmNLQ8Nw5fAVv5uCennR_mctq0bMkbKP http://fostrage.cyou/uyZS0obU8dY58erkWCygn-k5nRBygt6wmdXhnSh9To7faYDP Roll is a rotation about the longitudinal axis (equivalent to the rolling or heeling of a ship) giving an up-down movement of the wing tips measured by the roll or bank angle. Pitch is a rotation about the sideways horizontal axis giving an up-down movement of the aircraft nose measured by the angle of attack. Yaw is a rotation about the vertical axis giving a side-to-side movement of the nose known as sideslip. Flight dynamics is concerned with the stability and control of an aircraft's rotation about each of these axes. Stability The empennage of a Boeing 747-200 An aircraft that is unstable tends to diverge from its intended flight path and so is difficult to fly. A very stable aircraft tends to stay on its flight path and is difficult to maneuver. Therefore, it is important for any design to achieve the desired degree of stability. Since the widespread use of digital computers, it is increasingly common for designs to be inherently unstable and rely on computerised control systems to provide artificial stability. A fixed wing is typically unstable in pitch, roll, and yaw. Pitch and yaw stabilities of conventional fixed wing designs require horizontal and vertical stabilisers, which act similarly to the feathers on an arrow. These stabilizing surfaces allow equilibrium of aerodynamic forces and to stabilise the flight dynamics of pitch and yaw. They are usually mounted on the tail section (empennage), although in the canard layout, the main aft wing replaces the canard foreplane as pitch stabilizer. Tandem wing and tailless aircraft rely on the same general rule to achieve stability, the aft surface being the stabilising one. A rotary wing is typically unstable in yaw, requiring a vertical stabiliser. A balloon is typically very stable in pitch and roll due to the way the payload is slung underneath the center of lift. Control Flight control surfaces enable the pilot to control an aircraft's flight attitude and are usually part of the wing or mounted on, or integral with, the associated stabilizing surface. Their development was a critical advance in the history of aircraft, which had until that point been uncontrollable in flight. Aerospace engineers develop control systems for a vehicle's orientation (attitude) about its center of mass. The control systems include actuators, which exert forces in various directions, and generate rotational forces or moments about the aerodynamic center of the aircraft, and thus rotate the aircraft in pitch, roll, or yaw. For example, a pitching moment is a vertical force applied at a distance forward or aft from the aerodynamic center of the aircraft, causing the aircraft to pitch up or down. Control systems are also sometimes used to increase or decrease drag, for example to slow the aircraft to a safe speed for landing. The two main aerodynamic forces acting on any aircraft are lift supporting it in the air and drag opposing its motion. Control surfaces or other techniques may also be used to affect these forces directly, without inducing any rotation. ------------------------------ Date: Fri, 21 Aug 2020 10:01:15 -0400 From: "casino near me" Subject: This is Amazing!

The technology uses magnets to levitate the train above the track, reducing friction and allowing higher speeds. An early prototype was demonstrated in 1913. The first commercial maglev train was an airport shuttle introduced in 1984 at Birmingham Airport in England. The Shanghai Maglev Train, opened in 2003, is the fastest commercial train service of any kind, operating at speeds of up to 430 km/h (270 mph). Maglev has not yet been used for inter-city mass transit routes. Railcar Main article: Railcar The Bombardier Talent articulated regional railcar In British and Australian English, a "railcar" is a self-propelled railway vehicle designed to transport passengers. The term is usually used in reference to a train consisting of a single passenger car (carriage, coach) with a driver's cab at one or both ends. Some railways, e.g. the Great Western Railway, used the term "railmotor". If the railcar is able to pull a full train, it is more likely to be called a "motor coach" or a "motor car". The term "railcar" is sometimes also used as an alternative name for the small types of multiple unit that consist of more than one coach. Other types A British heritage passenger train hauled by the historic locomotive Flying Scotsman Named trains See also: Lists of named passenger trains Railway companies often give a name to a train service as a marketing exercise, to attract more passengers and gain recognition for the company. Naming is usually reserved for the most prestigious services, such as high-speed express trains that run between major cities, stopping at few intermediate stations, or for particularly luxurious trains. The names of special passenger trains have passed into popular culture: the Orient Express has been a setting for films and other works of fiction. The Flying Scotsman, Golden Arrow, and Royal Scot are examples of famous British trains; the Texas Eagle and California Zephyr are particularly well known in the US; and the Red Arrow is a celebrated Russian sleeper train. In India, some of the popular specially-named train services are the Brindavan Express (ChennaibBengaluru), Deccan Queen (Mumbai CSTbPune), and Flying Ranee (Mumbai CentralbSurat). A less common practice is the naming of freight trains, for the same commercial reasons. In the 1960s, the Condor was an overnight London to Glasgow express goods train, hauled by pairs of Metro-Vick diesel locomotives. In the mid-1960s, British Rail introduced the Freightliner brand, for the new train services carrying containers between dedicated terminals around the rail network. The Rev. W. Awdry also named freight trains, coining the name "Flying Kipper" for the overnight express fish train that appeared in his stories in The Railway Series books. ------------------------------ Date: Fri, 21 Aug 2020 08:00:26 -0400 From: "Early Life Blindness" Subject: Brain Scan Uncovers Root Cause For Vision Loss Brain Scan Uncovers Root Cause For Vision Loss http://hockets.buzz/JOc-RNt7I5NwfBo0J8KPLFsW-GaWfeM5xt2fvAhgafo_UvVf http://hockets.buzz/bJ-PwhgG6rl2KBDoH_PiPPDDRqD8meAnNW5pJQDGsY6sRhse amounts of time, the land speed record for human-powered vehicles (unpaced) is 133 km/h (83 mph), as of 2009 on a recumbent bicycle. The most common type of energy source is fuel. External combustion engines can use almost anything that burns as fuel, whilst internal combustion engines and rocket engines are designed to burn a specific fuel, typically gasoline, diesel or ethanol. Another common medium for storing energy is batteries, which have the advantages of being responsive, useful in a wide range of power levels, environmentally friendly, efficient, simple to install, and easy to maintain. Batteries also facilitate the use of electric motors, which have their own advantages. On the other hand, batteries have low energy densities, short service life, poor performance at extreme temperatures, long charging times, and difficulties with disposal (although they can usually be recycled). Like fuel, batteries store chemical energy and can cause burns and poisoning in event of an accident. Batteries also lose effectiveness with time. The issue of charge time can be resolved by swapping discharged batteries with charged ones; however, this incurs additional hardware costs and may be impractical for larger batteries. Moreover, there must be standard batteries for battery swapping to work at a gas station. Fuel cells are similar to batteries in that they convert from chemical to electrical energy, but have their own advantages and disadvantages. Electrified rails and overhead cables are a common source of electrical energy on subways, railways, trams, and trolleybuses. Solar energy is a more modern development, and several solar vehicles have been successfully built and tested, including Helios, a solar-powered aircraft. Nuclear power is a more exclusive form of energy storage, currently limited to large ships and submarines, mostly military. Nuclear energy can be released by a nuclear reactor, nuclear battery, or repeatedly detonating nuclear bombs. There have been two experiments with nuclear-powered aircraft, the Tupolev Tu-119 and the Convair X-6. Mechanical strain is another method of storing energy, whereby an elastic band or metal spring is deformed and releases energy as it is allowed to return to its ground state. Systems employing elastic materials suffer from hysteresis, and metal springs are too dense to be useful in many cases.[clarification needed] Flywheels store energy in a spinning mass. Because a light and fast rotor is energetically favorable, flywheels can pose a significant safety hazard. Moreover, flywheels leak energy fairly quickly and affect a vehicle's steering through the gyroscopic effect. They have been used experimentally in gyrobuses. Wind energy is used by sailboats and land yachts as the primary source of energy. It is very cheap and fairly easy to use, the main issues being dependence on weather and upwind performance. Balloons also rely on the wind to move horizontally. Aircraft flying in the jet stream may get a boost from high altitude winds. Compressed gas is currently an experimental method of storing energy. In this case, compressed gas is simply stored in a tank and released when necessary. Like elastics, they have hysteresis losses when gas heats up during compression. Gravitational potential energy is a form of energy used in gliders, skis, bobsleds and numerous other vehicles that go down hill. Regenerative braking is an example of capturing kinetic energy where the brakes of a vehicle are augmented with a generator or other means of extracting energy ------------------------------ Date: Thu, 20 Aug 2020 09:10:08 -0400 From: "2-4 Inches Bigger In 5 Steps" <2-4InchesBiggerIn5Steps@valuatin.buzz> Subject: These 3 Guys All Grew - Hear Their Stories These 3 Guys All Grew - Hear Their Stories http://valuatin.buzz/XZNLS8kY5VHDMNXmjxXv8eHUKrjjkCw3cRLtZ8McwsVlzLJA http://valuatin.buzz/g7vB_ynlV4KZM5CSNiCoAYJbYQ2wnP-Bmez3c1eS_sVGjcJz The results of cryptanalysis can also vary in usefulness. For example, cryptographer Lars Knudsen (1998) classified various types of attack on block ciphers according to the amount and quality of secret information that was discovered: Total break b the attacker deduces the secret key. Global deduction b the attacker discovers a functionally equivalent algorithm for encryption and decryption, but without learning the key. Instance (local) deduction b the attacker discovers additional plaintexts (or ciphertexts) not previously known. Information deduction b the attacker gains some Shannon information about plaintexts (or ciphertexts) not previously known. Distinguishing algorithm b the attacker can distinguish the cipher from a random permutation. Academic attacks are often against weakened versions of a cryptosystem, such as a block cipher or hash function with some rounds removed. Many, but not all, attacks become exponentially more difficult to execute as rounds are added to a cryptosystem, so it's possible for the full cryptosystem to be strong even though reduced-round variants are weak. Nonetheless, partial breaks that come close to breaking the original cryptosystem may mean that a full break will follow; the successful attacks on DES, MD5, and SHA-1 were all preceded by attacks on weakened versions. In academic cryptography, a weakness or a break in a scheme is usually defined quite conservatively: it might require impractical amounts of time, memory, or known plaintexts. It also might require the attacker be able to do things many real-world attackers can't: for example, the attacker may need to choose particular plaintexts to be encrypted or even to ask for plaintexts to be encrypted using several keys related to the secret key. Furthermore, it might only reveal a small amount of information, enough to prove the cryptosystem imperfect but too little to be useful to real-world attackers. Finally, an attack might only apply to a weakened version of cryptographic tools, like a reduced-round block cipher, as a step towards breaking of the full system. History Main article: History of cryptography Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptographybnew ciphers being designed to replace old broken designs, and new cryptanalytic techniques invented to crack the improved schemes. In practice, they are viewed as two sides of the same coin: secure cryptography requires design against possible cryptanalysis.[citation needed] Classical ciphers First page of Al-Kindi's 9th century Manuscript on Deciphering Cryptographic Messages See also: Frequency analysis, Index of coincidence, and Kasiski examination Although the actual word "cryptanalysis" is relatively recent (it was coined by William Friedman in 1920), methods for breaking codes and ciphers are much older. David Kahn notes in The Codebreakers that Arab scholars were the first people to systematically document cryptanalytic methods. ------------------------------ End of alt.music.moxy-fruvous digest V14 #4815 **********************************************
