The Alps were formed over hundreds of millions of years as the African and Eurasian tectonic plates collided ; the extreme compression caused by the event resulted in marine sedimentation rising and folding into high mountain peaks such as Mont Blanc and the Matterhorn.

This is why a high compression engine requires fuels specially formulated to not self-ignite ( which would cause engine knocking when operated under these conditions of temperature and pressure ), or that a supercharger and intercooler to provide a lower temperature at the same pressure would be advantageous.

A diesel engine operates under even more extreme conditions, with compression ratios of 20: 1 or more being typical, in order to provide a very high gas temperature which ensures immediate ignition of injected fuel.

Many file archivers employ archive formats that provide lossless data compression to reduce the size of the archive which is often useful for transferring a large number of individual files over a high latency network like the Internet.

Due to engine knocking ( detonation ), the compression ratio in a gasoline or petrol-powered engine will usually not be much higher than 10: 1, although some production automotive engines built for high-performance from 1955 – 1972 had compression ratios as high as 13. 0: 1, which could run safely on the high-octane leaded gasoline then available.

A technique used to prevent the onset of knock is the high " swirl " engine that forces the intake charge to adopt a very fast circular rotation in the cylinder during compression that provides quicker and more complete combustion.

Motorcycle racing engines can use compression ratios as high as 14: 1, and it is not uncommon to find motorcycles with compression ratios above 12. 0: 1 designed for 86 or 87 octane fuel.

An engine with high static compression ratio and late intake valve closure will have a DCR similar to an engine with lower compression but earlier intake valve closure.

Lossless compression is unable to attain high compression ratios due to the complexity of wave forms and the rapid changes in sound forms.

analog intervals ) and high compression ( small integers generated ).

The diesel engine has the highest thermal efficiency of any regular internal or external combustion engine due to its very high compression ratio.

This high compression heats the air to.

As well as the high level of compression allowing combustion to take place without a separate ignition system, a high compression ratio greatly increases the engine's efficiency.

Because of the relatively high bit rate of uncompressed video, video compression is extensively used.

On the east is the Elbląg Upland ( Wysoczyzna Elbląska ), a dome pushed up by glacial compression, 390 km < sup > 2 </ sup > in diameter and high at its greatest elevation.

The combustion process typically results in the production of a great quantity of heat, as well as the production of steam and carbon dioxide and other chemicals at very high temperature ; the temperature reached is determined by the chemical make up of the fuel and oxidisers ( see stoichiometry ), as well as by the compression and other factors.

As the nuclear warhead reenters the Earth's atmosphere its high speed causes compression of the air, leading to a dramatic rise in temperature which would destroy it if it were not shielded in some way.

There are no sit-down interviews, and the shooting ratio ( the amount of film shot to the finished product ) is very high, often reaching 80 to one.

A column with a high reflux ratio may have fewer stages, but it refluxes a large amount of liquid, giving a wide column with a large holdup.

Conversely, factors that favor plate columns are: presence of solids in feed, high liquid rates, large column diameters, complex columns, columns with wide feed composition variation, columns with a chemical reaction, absorption columns, columns limited by foundation weight tolerance, low liquid rate, large turn-down ratio and those processes subject to process surges.

According to reliabilism, a belief is justified ( or otherwise supported in such a way as to count towards knowledge ) only if it is produced by processes that typically yield a sufficiently high ratio of true to false beliefs.

Automotive engines must also be able to start reliably at-30 ° C (- 22 ° F ) and have a high power to volume ratio ( typically 2. 5 kW per liter ).

He began to increasingly focus on performing and later claimed: " With time I became disenchanted with teaching because the ratio of girls to boys was more than ten to one, and once the girls reached sixteen the dropout rate was very high.

It is extremely difficult to over water coir due to its perfect air-to-water ratio, plant roots thrive in this environment, coir has a high cation exchange, meaning it can store unused minerals to be released to the plant as and when it requires it.

The ice beers are typically known for their high alcohol-to-dollar ratio.

As it is, they consider that the North is now reaping the fruits of excess egalitarianism, that in spite of its high standard of living the `` American way '' has been proved inferior to the English and Scandinavian ways, although they disapprove of the socialistic features of the latter.
