Coefficient of Thermal Expansion $73.28 High Quality Content by WIKIPEDIA articles All materials change their size when subjected to a temperature change as long as the pressure is held constant. In the special case of solid materials, the pressure does not appreciably affect the size of an object, and so for solids, it usually not necessary to specify that the pressure be held constant. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional change in volume per degree change in temperature at a constant pressure. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient. All substances expand or contract when their temperature changes, and the expansion or contraction always occurs in all directions. Substances that expand at the same rate in any direction are called isotropic. Unlike gases or liquids, solid materials tend to keep their shape. For solids, one might only be concerned with the change along a length, or over some area. Expansion coefficients are specially defined for these cases, and they are known as the linear and area expansion coefficients.

Coefficient of Relationship $68.51 High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles In population genetics, Sewall Wrights coefficient of relationship or coefficient of relatedness or relatedness or r is defined as 2 times the coefficient of kinship. The coefficient of kinship is defined as the probability that the alleles at a particular locus chosen at random from two individuals are identical by descent. For example, in a diploid species (e.g. all mammals), the coefficient of relationship between parent and offspring is 0.5, meaning half of the offsprings genome comes from that parent. Or, more precisely said, half the genes are identical by descent. Some other relatedness examples: (assuming no consanguinity, for diploid species unless noted otherwis).

Differential Coefficient $60.54 In mathematics, the differential coefficient of a function f(x) is what is now called its derivative df(x)/dx, the (not necessarily constant) multiplicative factor or coefficient of the differential dx in the differential df(x). A coefficient is usually a constant quantity, but the differential coefficient of f is a constant function only if f is a linear function. When f is not lineive#Differen, hence, the modern term, derivative. Early editions of Silvanus P. Thompsons Calculus Made Easy use the older term. Martin Gardner lets the first use of differential coefficient stand, along with Thompsons criticism of the term as a needlessly obscure phrase that should not intimidate students, and substitutes derivative for the remainder of the book.

Pressure Coefficient $84.44 High Quality Content by WIKIPEDIA articles The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own unique pressure coefficient, Cp. In many situations in aerodynamics and hydrodynamics, the pressure coefficient at a point near a body is independent of body size. Consequently an engineering model can be tested in a wind tunnel or water tunnel, pressure coefficients can be determined at critical locations around the model, and these pressure coefficients can be used with confidence to predict the fluid pressure at those critical locations around a fullsize aircraft or boat. The pressure coefficient is a very useful parameter for studying the flow of incompressible fluids such as water, and also the lowspeed flow of compressible fluids such as air.

Coefficient of Performance $60.54 High Quality Content by WIKIPEDIA articles The coefficient of performance or COP, of a heat pump is the ratio of the change in heat at the output to the supplied work. The COP for heating and cooling are thus different, because the heat reservoir of interest is different. When one is interested in how well a machine cools, the COP is the ratio of the heat removed from the cold reservoir to input work. However, for heating, the COP is the ratio of the heat removed from the cold reservoir plus the heat added to the hot reservoir by the input work.

Standardized Coefficient $58.94 High Quality Content by WIKIPEDIA articles In statistics, standardized coefficients or beta coefficients are the estimates resulting from an analysis performed on variables that have been standardized so that they have variances of 1. This is usually done to answer the question of which of the independent variables have a greater effect on the dependent variable in a multiple regression analysis, when the variables are measured in different units of measurement (for example, income measured in dollars and family size measured in number of individuals). Before fitting the multiple regression equation, all variables (independent and dependent) can be standardized by subtracting the mean and dividing by the standard deviation. The standardized regression coefficients, then, represent the change in terms of standard deviations in the dependent variable that result from a change of one standard deviation in an independent variable. Some statistical software packages like PSPP/SPSS report them automatically, labeling them Beta while the ordinary unstandarized coefficients are labeled B. Others, like DAP/SAS, provide them as an option and label them Standardized Coefficient. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Heat Transfer Coefficient $81.25 The heat transfer coefficient, in thermodynamics and in mechanical and chemical engineering, is used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid: From the above equation, the heat transfer coefficient is the proportionality coefficient between the heat flux, Q/, and the thermodynamic driving force for the flow of heat. The heat transfer coefficient has SI units in watts per meter squaredkelvin. Heat transfer coefficient is the inverse of thermal insulance. There are numerous methods for calculating the heat transfer coefficient in different heat transfer modes, different fluids, flow regimes, and under different thermohydraulic conditions. Often it can be estimated by dividing the thermal conductivity of the convection fluid by a length scale. The heat transfer coefficient is often calculated from the Nusselt number.

A Study of Additive Coefficient Models. $115.71 This dissertation extends spline smoothing methods to additive coefficient models. The computational approach employs a novel combination of Kalman filtering and backfitting methodology. The overall computational effort required to evaluate the estimator is O(Nd), with d the number of effect modifying variables and N the sample size. It also develops an algorithm for computing the generalized crossvalidation criterion for selection of smoothing parameters that can be accomplished in concert with iterative evaluation of the coefficient function estimators. Bayesian confidence intervals for each coefficient function are provided as part of the estimation algorithm.

Simulation of Ingan Blue Laser Diode $172.06 In this book, the design of InGaN LDs structures including multi quantum wells (MQWs) active region device are described and investigated by integrated system engineering technology computer aided design (ISE TCAD) device simulator. The parameters of the LDs structures are varied and optimized for high performance. This optimization study involves aspects such as thickness of active region, doping, thickness of stopper layer region, thickness of quantum wells and quantum barriers, number of quantum wells and several approaches to improve and achieve high efficiency, low threshold current and high output power of InGaN LDs. The basic LDs structures treated here are FabryPerot type InGaN double heterostructure (DH), separate confinement heterostructure (SCH) and multi quantum wells (MQWs).High performance LD has been obtained by using multi quantum wells incorporated with the optimized parameters. The lowest threshold current, higher external quantum efficiency and characteristic temperature are obtained when the number of InGaN well layers is two, at our laser emission wavelength of 415 nm, which is related to the problem of inhomogeneous carrier.
