  • seismic inverse q filtering

    seismic inverse q filtering is a data processing technology for enhancing the resolution of reflection seismology images. q is the anelastic attenuation factor or the seismic quality factor, a measure of the energy loss as the seismic wave moves.

  • filter signal processing

    in signal processing, a filter is a device or process that removes some unwanted components or features from a signal.filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal.most often, this means removing some frequencies or frequency bands. however, filters do not exclusively act in the frequency domain .

  • wiener filter

    the causal finite impulse response fir wiener filter, instead of using some given data matrix x and output vector y, finds optimal tap weights by using the statistics of the input and output signals. it populates the input matrix x with estimates of the auto-correlation of the input signal t and populates the output vector y with estimates of the cross-correlation between the output and .

  • downsampling signal processing

    in digital signal processing, downsampling, compression, and decimation are terms associated with the process of resampling in a multi-rate digital signal processing system. both downsampling and decimation can be synonymous with compression, or they can describe an entire process of bandwidth reduction and sample-rate reduction. when the process is performed on a sequence of samples of a .

  • analogue filter

    there are three main stages in the history of passive analogue filter development: simple filters. the frequency dependence of electrical response was known for capacitors and inductors from very early on. the resonance phenomenon was also familiar from an early date and it was possible to produce simple, single-branch filters with these .

  • finite impulse response

    in signal processing, a finite impulse response fir filter is a filter whose impulse response or response to any finite length input is of finite duration, because it settles to zero in finite time. this is in contrast to infinite impulse response iir filters, which may have internal feedback and may continue to respond indefinitely usually decaying .

  • s10 nbc respirator

    the s10 was introduced in 1986 as a replacement for the s6 nbc respirator in service from the 1960s, and is manufactured by avon rubber. s10s were issued to british nationals in saudi arabia during the 1991 gulf war and were marked by a blue coloured psm primary speech module fitting or a blue painted spot on the forehead.. the s10 respirator was originally due to be replaced by the new .

  • membrane bioreactor

    membrane bioreactor mbr is the combination of a membrane process like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge is now widely used for municipal and industrial wastewater treatment.

  • belt filter

    the belt filter is mainly used for dewatering of sludge and slurry and juice extraction from apples, pears and other fruits, as well as grapes for winemaking, etc. belt filters are used both municipally and industrially in a range of areas including urban sewage and wastewater treatment, metallurgy and mining, steel plants, coal plants, breweries, dyeing, tanneries, as well as chemical and paper factories.

  • filter mathematics

    in mathematics, a filter is a special subset of a partially ordered set.filters appear in order and lattice theory, but can also be found in topology, from where they originate.the dual notion of a filter is an order ideal.. filters were introduced by henri cartan in 1937 and subsequently used by bourbaki in their book topologie générale as an alternative to the similar notion of a net .

  • broadbent's filter model of attention

    the early selection model of attention, proposed by broadbent, posits that stimuli are filtered, or selected to be attended to, at an early stage during processing. a filter can be regarded as the selector of relevant information based on basic features, such as color, pitch, or direction of stimuli.

  • low-pass filter

    a low-pass filter lpf is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. the exact frequency response of the filter depends on the filter design.the filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. a low-pass filter is the complement of a .

  • lamella clarifier

    a lamella clarifier or inclined plate settler ips is a type of settler designed to remove particulates from liquids. they are often employed in primary water treatment in place of conventional settling tanks. they are used in industrial water treatment. unlike conventional clarifiers they use a series of inclined plates. these inclined plates provide a large effective settling area for a small footprint.

  • trickling filter

    a trickling filter is a type of wastewater treatment system. it consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime to grow, covering the bed of media. aerobic conditions are maintained by splashing, diffusion, and either by forced-air .
