Heat transfer coefficient Heat transfer coefficient. The heat transfer coefficient or film coefficient, or film effectiveness, in thermodynamics and in mechanics is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, δT): where:

Bearing In the illustration, the inner race turns with the shaft. Under certain combinations of load, speed, fluid viscosity, and bearing geometry, a fluid film forms and separates the contacting surfaces in a sliding bearing; this is known as a hydrodynamic film.

- The Speaker of the House is the only House leadership position mentioned in the Constitution. Over time, as the United States grew and the membership of the U.S. House of Representatives increased, a need for additional leaders developed.very two years, the Members of the U.S. House of Representatives vote on the first day of each new Congress. Both of the major political parties nominate one candidate for the position of Speaker. The candidate from the majority party usually wins.

coefficient correlation coefficient a numerical value that indicates the degree and direction of relationship between two variables; the coefficients range in value from +1.00 (perfect positive relationship) to 0.00 (no relationship) to −1.00 (perfect negative or inverse relationship).

- Correlation Coefficient is a vital aspect used in statistics to calculate the strength and direction of the linear relationship or the statistical relationship (correlation) between the two population data sets. In the formula, the symbols μx and μy represents the mean of the two data sets X and Y respectively.

Correlation Coefficients Correlation Coefficient. A number that is a measure of the strength and direction of the correlation between two variables. Correlation coefficients are expressed using the variable r, where r is between 1 and –1, inclusive. The closer r is to 1 or –1, the less scattered the points are and the stronger the relationship. Only data points with a scatterplot which is a perfectly straight line can have r = –1 or r = 1.

What is the 'Correlation Coefficient' What is the 'Correlation Coefficient'. The correlation coefficient is a measure that determines the degree to which two variables' movements are associated. The range of values for the correlation coefficient is -1.0 to 1.0. If a calculated correlation is greater than 1.0 or less than -1.0, a mistake has been made.

Film festival Grand Jury Prize redirects here. For the prize at the Venice Film Festival, see Grand Jury Prize (Venice Film Festival). A film festival is an organised, extended presentation of films in one or more cinemas or screening venues, usually in a single city or region. Increasingly, film festivals show some films outdoors. Films may be of recent date and, depending upon the festival's focus, can include international and domestic releases.

What is the Damping Coefficient of Materials? What is the Damping Coefficient of Materials? A damping coefficient is a material property that indicates whether a material will bounce back or return energy to a system. For example, a basketball has a low damping coefficient (a good bounce back). If the bounce is caused by an unwanted vibration or shock, a high damping coefficient in the material will diminish the response. It will swallow the energy and reduce the undesired reaction.

Coefficient of determination The coefficient of determination R 2 is a measure of the global fit of the model. Specifically, R 2 is an element of [0, 1] and represents the proportion of variability in Y i that may be attributed to some linear combination of the regressors (explanatory variables) in X.

Partition coefficient In the physical sciences, a partition-coefficient (P) or distribution-coefficient (D) is the ratio of concentrations of a compound in a mixture of two immiscible phases at equilibrium. This ratio is therefore a measure of the difference in solubility of the compound in these two phases.

- For the genre of films, see slow cinema. Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to measure the sensitivity of digital imaging systems. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film.

Film transition A film transition is a technique used in the post-production process of film editing and video editing by which scenes or shots are combined. Most commonly this is through a normal cut to the next shot.

coefficient of friction coefficient of friction. A measure of the amount of resistance that a surface exerts on or substances moving over it, equal to the ratio between the maximal frictional force that the surface exerts and the force pushing the object toward the surface.

Coefficient of determination The coefficient of determination R 2 is a measure of the global fit of the model. Specifically, R 2 is an element of [0, 1] and represents the proportion of variability in Y i that may be attributed to some linear combination of the regressors (explanatory variables) in X.n this form R 2 is expressed as the ratio of the explained variance (variance of the model's predictions, which is SS reg / n) to the total variance (sample variance of the dependent variable, which is SS tot / n).

Coefficient of Variation Coefficient of Variation. In statistics, the ratio of the standard deviation of a series of data points to the expected return. In investing, the coefficient of variation is used to measure the volatility (represented by the standard deviation) to the expected return on an investment.A lower coefficient of variation indicates a higher expected return with less risk.n investing, the coefficient of variation is used to measure the volatility (represented by the standard deviation) to the expected return on an investment.

Film Thickness Film thickness is the depth of the coating applied. Film thickness can be broadly classified as: Wet film thickness - Wet film thickness (WFT) is the thickness of wet paint or any coating film that is liquid-based. Wet thickness is at its peak right after the application of the coating.

Coefficient of variation In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution.t is often expressed as a percentage, and is defined as the ratio of the standard deviation to the mean (or its absolute value,). The CV or RSD is widely used in analytical chemistry to express the precision and repeatability of an assay.

Attenuation coefficient A large attenuation coefficient means that the beam is quickly attenuated (weakened) as it passes through the medium, and a small attenuation coefficient means that the medium is relatively transparent to the beam.The SI unit of attenuation coefficient is the reciprocal metre (m −1). small attenuation coefficient indicates that the material in question is relatively transparent, while a larger value indicates greater degrees of opacity. The attenuation coefficient is dependent upon the type of material and the energy of the radiation.

Coefficient of Determination (R-Squared) Purpose. Coefficient of determination (R-squared) indicates the proportionate amount of variation in the response variable y explained by the independent variables X in the linear regression model. The larger the R-squared is, the more variability is explained by the linear regression model.
