calibration stability
1Color calibration — The aim of color calibration is to measure and/or adjust the color response of a device (input or output) to a known state. In ICC terms this is the basis for a additional color characterization of the device and later profiling[1]. In non ICC… …
2Measurement microphone calibration — In order to take a scientific measurement with a microphone, its precise sensitivity must be known (in volts per Pascal). Since this may change over the lifetime of the device, it is necessary to regularly calibrate measurement microphones. This… …
3Ghrsst-pp — The Global Ocean Data Assimilation Experiment (GODAE) high resolution sea surface temperature pilot project (GHRSST PP) provides a new generation of global high resolution ( …
4Scattering parameters — or S parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering describing the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small… …
5Fast Kalman filter — The fast Kalman filter (FKF), devised by Antti Lange (1941 ), is an extension of the Helmert Wolf blockingfn|1 (HWB) method from geodesy to real time applications of Kalman filtering (KF) such as satellite imaging of the Earth. Kalman filters are …
6Microelectromechanical system oscillator — Microelectromechanical system (MEMS) oscillators are timing devices that generate highly stable reference frequencies. These reference frequencies are used to sequence electronic systems, manage data transfer, define radio frequencies, and… …
7Network analyzer (electrical) — Not to be confused with packet analyzer or telecom network protocol analyzer. ZVA40 vector network analyser from Rohde Schwarz. A network analyzer is an instrument that measures the network parameters of electrical networks. Today, network… …
8Kilogram — Kg redirects here. For other uses, see Kg (disambiguation). Kilogram A computer generated image of the international prototype kilogram (IPK). The IPK is the kilogram. The IPK, which is roughly the size of a golf ball, sits here alongside a ruler …
9Earth Sciences — ▪ 2009 Introduction Geology and Geochemistry The theme of the 33rd International Geological Congress, which was held in Norway in August 2008, was “Earth System Science: Foundation for Sustainable Development.” It was attended by nearly… …
10Sea level rise — is an increase in sea level. Multiple complex factors may influence this change. Sea level has risen about 130 meters (400 ft) since the peak of the last ice age about 18,000 years ago. Most of the rise occurred before 6,000 years ago. From 3,000 …
