Bamboo Filters were introduced in 2007.

Filters with bandpasses overlapping as little as possible were desirable.

Filters were added late into construction at the insistence of Sir John Cockcroft and these were housed in galleries at the very top of the discharge stacks.

Filters were also used to inject pale blues into the scene being filmed.

These may be heuristics-based such as the Extended Kalman Filter or the Assumed Density Filters described in Peter S. Maybeck's book or more methodologically driven such as the projection filters introduced by Damiano Brigo, Bernard Hanzon and François Le Gland, some sub-families of which are shown to coincide with the Assumed Density Filters.

Filters can be implemented in many different ways: by a software program on a personal computer, via network infrastructure such as proxy servers that provide Internet access.

Filters can be represented by block diagrams, which can then be used to derive a sample processing algorithm to implement the filter with hardware instructions.

X-rays are generally filtered ( by use of X-Ray Filters ) to a single wavelength ( made monochromatic ) and collimated to a single direction before they are allowed to strike the crystal.

: " Fade Away ", accompanied by friend and Oasis fan Johnny Depp and Depp's then-girlfriend Kate Moss ; and The Beatles ' 1969 hit " Come Together ", along with Paul Weller, Paul McCartney and others in a supergroup called Smokin ' Mojo Filters.

: Filters can redirect requests to different web pages or to local files, either by sending the new location as a directive to the browser or by " transparently " connecting to the new location directly.

Filters, filter sets, compatible DLLs and other files, and GUI patches to restyle and / or update Proxomitron's graphical user interface are also being provided by users.

For example, G841 is a dark blue made by Great American Market ( GAM ), and R02 is a light amber made by Rosco and L216 is a diffusion filter made by Lee Filters.

Filters such as A-weighting attempt to adjust sound measurements to correspond to loudness as perceived by the typical human.

Filters can also be used to partially compensate for the effects of light pollution by blocking out unwanted light.

Filters by various methods:

Filters with excessively strong water intake are dangerous because this little fish is prone to get sucked in by strong currents, perhaps even more so than the neon tetra.

In a 1985 song by Jan Krzysztof Kelus the name of the cigarettes is compared to Auschwitz Filters due to the fact that many thousands of Gulag prisoners had died during the construction of the Canal.

Filters that use reverse osmosis, those labeled as “ absolute one micron filters ,” or those labeled as certified by an American National

* A version of The Beatles ' song " Come Together ", by new supergroup the Smokin ' Mojo Filters: Paul McCartney, Paul Weller, Noel Gallagher, Steve Cradock, Steve White, and Carleen Anderson.

Filters using passive filter and active filter technology can be further classified by the particular electronic filter topology used to implement them.

Filters of this type can be used to equalize the group delay of recursive filters.

Filters, such as diffusion filters or color-effect filters, are also widely used to enhance mood or dramatic effects.

Filters can be used in front of the lens or, in some cases, behind the lens for different effects.

Filters are frequently used to achieve impedance matching in telecommunications and radio engineering.

Filters, usually thin pieces of colored plastic, can be used to increase or decrease an image's contrast ( the difference between dark tones and light tones ).

Filters are used to view an object at particular frequencies or frequency ranges.

Filters are often used to remove solid substances suspended in fluids, for example to remove air pollution, to make water drinkable, and to prepare coffee.

Filters and / or monochromators may be used in fluorimeters.

Slow filter in " Warsaw Water Filters | Filtry Lindleya ", WarsawSlow sand filters are used in water purification for treating raw water to produce a potable product.

Filters are used in many aspects of audiology and psychoacoustics including the peripheral auditory system.

Filters are used to prevent spikes entering or leaving the equipment through wires, and the devices coupled electromagnetically to space ( such as radio-frequency pick-up coils in MRI scanners ) are protected by shielding.

* Filters out virtually all particles larger than their specified pore sizes.

Other color manufacturers, such as Lee Filters and Apollo Design Technology use polyester as their color substrate.

Filters in photography can be classified according to their use:

Filters may have fine meshes that must be replaced or cleaned, and ceramic water filters must have their outside abraded when they have become clogged with impurities.

* Email Filters allow users to delete messages, send message to other email address and to their cellphones and pagers.

In their 1977 article ‘ Filters and Control ,’ Chomsky and Howard Lasnik extended this to view markedness as part of a theory of ‘ core grammar :’

Filters are similar to Wrappers in the search approach, but instead of evaluating against a model, a simpler filter is evaluated.
