31Pulse-density modulation — Pulse density modulation, or PDM, is a form of modulation used to represent an analog signal in the digital domain. In a PDM signal, specific amplitude values are not encoded into pulses as they would be in PCM. Instead it is the relative density …
32Exposure range — In photography, exposure range is one of several types of dynamic range:* The Light sensitivity range of photographic film, paper, or digital camera sensors. * The luminosity range of a scene being photographed. * The opacity range of developed… …
33Coast Range (ecoregion) — The Coast Range ecoregion is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in the U.S. states of Washington, Oregon, and California. It stretches along the Pacific Coast from the tip of the Olympic Peninsula in the …
34High-density lipoprotein — High density lipoproteins (HDL) is one of the 5 major groups of lipoproteins (chylomicrons, VLDL, IDL, LDL, HDL) which enable lipids like cholesterol and triglycerides to be transported within the water based blood stream. In healthy individuals …

36Recurrence period density entropy — (RPDE) is a method, in the fields of dynamical systems, stochastic processes, and time series analysis, for determining the periodicity, or repetitiveness of a signal. Overview Recurrence period density entropy is useful for characterising the… …
37Interquartile range — In descriptive statistics, the interquartile range (IQR), also called the midspread, middle fifty and middle of the #s, is a measure of statistical dispersion, being equal to the difference between the third and first quartiles.Unlike the (total) …
38Graduated neutral density filter — A graduated neutral density filter, also known as a graduated ND filter, split neutral density filter, or just a graduated filter, is an optical filter that has a variable light transmission. Typically half of the filter is of neutral density… …
39Ultra Density Optical — (UDO) is an optical disc format designed for high density storage of high definition video and data. Overview An Ultra Density Optical disc or UDO is a 133.35 mm (5.25 ) ISO cartridge optical disc which can store up to 60 GB of… …
40Variable range hopping — IntroductionVariable range hopping or Mott variable range hopping, is a model describing low temperature conduction in strongly disordered systems with localized states. [Mott, N.F., Phil. Mag. ,19,835,1969] It has a characteristic temperature… …
