  • list of map projections

    list of map projections. jump to navigation jump to search. this is a summary of map projections that have articles of their own on wikipedia or that are otherwise notable. because there is no limit to the number of possible map projections, .

  • causal filter

    in signal processing, a causal filter is a linear and time-invariant causal system.the word causal indicates that the filter output depends only on past and present inputs. a filter whose output also depends on future inputs is non-causal, whereas a filter whose output depends only on future inputs is anti-causal.systems including filters that are realizable i.e. that operate in real time .

  • quincunx

    a quincunx / ˈ k w ɪ n. k ʌ ŋ k s / is a geometric pattern consisting of five points arranged in a cross, with four of them forming a square or rectangle and a fifth at its center. it forms the arrangement of five units in the pattern corresponding to the five-spot on six-sided dice, playing cards, and dominoes.it is represented in unicode as u 2059 ⁙ five dot punctuation or for the die .

  • photographic filter

    in photography and cinematography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path.the filter can be of a square or oblong shape and mounted in a holder accessory, or, more commonly, a glass or plastic disk in a metal or plastic ring frame, which can be screwed into the front of or clipped onto the camera lens.

  • windows metafile

    windows metafile wmf is an image file format originally designed for microsoft windows in the 1990s. the original windows metafile format was not device-independent though could be made more so with placement headers and may contain both vector graphics and bitmap components. it acts in a similar manner to svg files.

  • waveguide flange

    a waveguide flange is a connector for joining sections of waveguide, and is essentially the same as a pipe flange—a waveguide, in the context of this article, being a hollow metal conduit for microwave energy. the connecting face of the flange is either square, circular or particularly for large or reduced-height rectangular waveguides , rectangular.

  • ringing artifacts

    the main cause of ringing artifacts is due to a signal being bandlimited specifically, not having high frequencies or passed through a low-pass filter; this is the frequency domain description. in terms of the time domain, the cause of this type of ringing is the ripples in the sinc function, which is the impulse response time domain representation of a perfect low-pass filter.

  • backward euler method

    the region of absolute stability for the backward euler method is the complement in the complex plane of the disk with radius 1 centered at 1, depicted in the figure. this includes the whole left half of the complex plane, making it suitable for the solution of stiff equations. in fact, the backward euler method is even l-stable.

  • speckle interference

    the lee filter converts the multiplicative model into an additive one, thereby reducing the problem of dealing with speckle to a known tractable case. wavelet analysis. recently, the use of wavelet transform has led to significant advances in image analysis. the main reason for the use of multiscale processing is the fact that many natural .

  • rectangular function

    plot of sinc x function with its frequency spectral components. using angular frequency ω, where is the unnormalized form of the sinc function.. note that as long as the definition of the pulse function is only motivated by its behavior in the time-domain experience, there is no reason to believe that the oscillatory interpretation i.e. the fourier transform function should be intuitive .

  • voronoi diagram

    in mathematics, a voronoi diagram is a partition of a plane into regions close to each of a given set of objects. in the simplest case, these objects are just finitely many points in the plane called seeds, sites, or generators . for each seed there is a corresponding region consisting of all points of the plane closer to that seed than to any other.

  • sinc function

    in mathematics, the historical unnormalized sinc function is defined for x ≠ 0 by ⁡ = ⁡ . alternatively, the unnormalized sinc function is often called the sampling function, indicated as sa x .. in digital signal processing and information theory, the normalized sinc function is commonly defined for x ≠ 0 by ⁡ = ⁡ . in either case, the value at x = 0 is defined to be the .

  • sedimentation water treatment

    basics. suspended solids or ss , is the mass of dry solids retained by a filter of a given porosity related to the volume of the water sample. this includes particles 10 μm and greater. colloids are particles of a size between 1 nm 0.001 µm and 1 µm depending on the method of quantification.

  • envelope

    an envelope is a common packaging item, usually made of thin, flat material. it is designed to contain a flat object, such as a letter or card . traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross or a kite. these shapes allow for the creation of.

  • digital ion trap

    the digital ion trap dit is an quadrupole ion trap driven by digital signals, typically in a rectangular waveform, generated by switching rapidly between discrete dc voltage levels. the digital ion trap has been mainly developed as a mass analyzer.

  • sinc filter

    in signal processing, a sinc filter is an idealized filter that removes all frequency components above a given cutoff frequency, without affecting lower frequencies, and has linear phase response. the filter's impulse response is a sinc function in the time domain, and its frequency response is a rectangular function. it is an 'ideal' low-pass filter in the frequency sense, perfectly passing low frequencies, perfectly cutting high frequencies; and thus may be considered to be a brick-wall filter

  • intersymbol interference

    one of the causes of intersymbol interference is multipath propagation in which a wireless signal from a transmitter reaches the receiver via multiple paths. the causes of this include reflection for instance, the signal may bounce off buildings , refraction such as through the foliage of a tree and atmospheric effects such as atmospheric ducting and ionospheric reflection.

  • rectangle

    the word rectangle comes from the latin rectangulus, which is a combination of rectus as an adjective, right, proper and angulus . a crossed rectangle is a crossed self-intersecting quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals.

  • butterworth filter

    the butterworth filter is a type of signal processing filter designed to have a frequency response as flat as possible in the passband.it is also referred to as a maximally flat magnitude filter.it was first described in 1930 by the british engineer and physicist stephen butterworth in his paper entitled 'on the theory of filter amplifiers'.
