Crosstalk measurement is made on audio systems to determine the amount of signal leaking across from one channel to another. Interchannel crosstalk applies between the two channels of a stereo system, and is usually not very important on modern systems, though it was hard to keep below the desired figure of 30dB or so on vinyl record ings and FM radio . Crosstalk between channels in mixing consoles, and between studio feeds is much more of a problem, as these are likely to be carrying very different programmes or material. The IBA drew up a weighting curve for use in crosstalk measurement that gives due emphasis to the subjective audibility of different frequencies, as shown here. This is still in use, despite the demise of the IBA, and in the absence of any international standards is worth adopting.

It is concerned with the length of time it takes to complete a work task assigned to a specific job. Usage Work measurement helps to uncover non standardization that exist in the workplace and non value adding activities and waste. A work has to be measured for the following reasons To discover and eliminate lost or ineffective time. To establish standard times for performance measurement. To measure performance against realistic expectations. To set operating goals and objectives.

Measurement and Verification demonstrates how much energy the ECM has avoided using, rather than the total cost saved. The latter can be affected by many factors, such as energy prices.

Unreferenced stub auto yes date December 2009 Grade measurement is the geodesy geodetic determination of the local radius of curvature of the figure of the Earth by determining the difference in astronomical latitude between two locations on the same meridian geography meridian , the metric distance between which is known. The first known grade measurement was performed by Eratosthenes 240 BC between Alexandria and Syene in what is now Egypt, determining the radius of the Earth with remarkable correctness. The Dutch geodesist Snellius 1620 repeated the experiment between Alkmaar and Bergen op Zoom using more modern geodetic instrumentation. Later grade measurements aimed at determining the flattening of the Earth ellipsoid by measuring at different geographic latitude s. The first of these was the one commissioned by the French Geodesic Mission French Academy of Sciences in 1735 1738, involving measurement expeditions to Lapland Pierre Louis Maupertuis Maupertuis et al. and Peru Pierre Bouguer et al. . br Later, Struve measured a geodetic triangle chain between the Arctic Sea and the Black Sea, and Bessel compiled several arcs to compute the famous Bessel ellipsoid 1841 . Nowadays, the method is replaced by worldwide geodetic network s and by satellite geodesy .

Noise measurement is carried out in various fields. In acoustics , it can be for the purpose of measuring environmental noise , or part of a test procedure using white noise , or some other specialised form of test signal . In electronics it relates to the sensitivity of communications systems, the purity of signals, or the quality of audio systems . The concept is to define the noise level below which signals cannot reliably be detected. It can be thought of as uncertainty of the information being carried over a communications channel . In audio systems and broadcasting specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the differing spectral distribution and temporal properties of the noise that they generate. In particular, the ITU R 468 noise weighting was devised specifically for this purpose, and is widely used for professional audio and broadcast measurements. Standards There are a number of standards for noise measurement, each with a different goal or focus, including Standard ITU R BS 468 widely used in Broadcasting and professional Audio. Standard IEC A weighting is widely used in Environmental Noise measurement. Standard CCIR recommendation 468 4 is now maintained as ITU R BS 468 Standard CCITT 0.41 refers to Psophometric weighting used on telephone circuits. Standard CCITT P53 is now continued as CCITT0.41 Standard BS 6402 1983 specifies Personal sound exposure meters. Standard BS 3539 1968 specifies Sound level meter s for motor vehicle noise.

POV check date November 2010 Weak measurements are a type of quantum measurement , where the measured system is very weakly coupled to the measuring device. After the measurement the measuring device pointer is shifted by what is called the weak value . So that a pointer initially pointing at zero before the measurement would point at the weak value after the measurement. The system is not disturbed by the measurement. Although this may seem to contradict some basic aspects of quantum theory, the formalism lies within the boundaries of the theory and does not contradict any fundamental concept. The idea of weak measurements and weak values, first developed by Yakir Aharonov , David Albert and Lev Vaidman ref Y. Aharonov, D.Z. Albert, L.

merge Quantum mind body problem date November 2010 The measurement problem in quantum mechanics is the unresolved problem of how or if wavefunction collapse occurs. The inability to observe this process directly has given rise to different interpretations of quantum mechanics , and poses a key set of questions that each interpretation must answer. The wavefunction in quantum mechanics evolves according to the Schr dinger equation into a linear Quantum superposition superposition of different states, but actual measurements always find the physical system in a definite state. Any future evolution is based on the state the system was discovered to be in when the measurement was made, meaning that the measurement did something to the process under examination.
