Level sensor — Level sensors are used to detect liquid level. The liquid to be measured can be inside a container or can be in its natural form (e.g. a river or a lake). The level measurement can be either continuous or point values. Continuous level sensors… … Wikipedia
Error diffusion — is a type of halftoning in which the quantization residual is distributed to neighboring pixels which have not yet been processed. Its main use is to convert a multi level image into a binary image, though it has other applications.Unlike many… … Wikipedia
Frequency synthesizer — A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie… … Wikipedia
Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) … Wikipedia
Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… … Wikipedia
Cumulative frequency analysis — is the applcation of estimation theory to exceedance probability (or equivalently to its complement). The complement, the non exceedance probability concerns the frequency of occurrence of values of a phenomenon staying below a reference value.… … Wikipedia
Utility frequency — The waveform of 230 volt, 50 Hz compared with 110 V, 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the frequency at which alternating current (ac, also AC) is transmitted from a… … Wikipedia
Medical error — A medical error may be defined as a preventable adverse effect of care, whether or not it is evident or harmful to the patient. This might include an inaccurate or incomplete diagnosis or treatment of a disease, injury, syndrome, behavior,… … Wikipedia
Configural frequency analysis — (CFA) (Lienert, 1969) is a method of exploratory data analysis. The goal of a configural frequency analysis is to detect patterns in the data that occur significantly more (such patterns are called Types) or significantly less often (such… … Wikipedia
Single-frequency network — For other uses, see SFN (disambiguation). A single frequency network or SFN is a broadcast network where several transmitters simultaneously send the same signal over the same frequency channel. Contents 1 Overview 2 OFDM and COFDM 3 DVB T SFN … Wikipedia
Speech error — A speech error is a speech pattern that differs from some standard pattern. Speech errors are common among children, who have yet to refine their speech, and can frequently continue into adulthood. They sometimes lead to embarrassment and… … Wikipedia
