Determinant Expansion by Minors Also known as "Laplacian" determinant expansion by minors‚ expansion by minors is a technique for computing thedeterminant of a given square matrix . Although efficient for small matrices‚ techniques such as Gaussian elimination are much more efficient when the matrix size becomes large. Let denote the determinant of a matrix ‚ then where is a so-called minor of ‚ obtained by taking the determinant of with row and column "crossed out." For example‚ for a matrix

Experiment 1: Thermal Linear Expansion Abstract: The thermal linear expansion of copper and aluminum is the focus of this experiment where the two metals have a tendency to expand their length in response to the change of temperature. Each metals have their own coefficient of linear expansion which describes how the size of an object changes with a change in temperature while the pressure is held constant. We ’re able to determine the theoretical coefficient of linear expansion of the two metals by substituting

Page 1 of 4 Expansion Devices I. Introduction Expansion devices are basic components of a refrigeration system which carry out two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass

Clive Beddoe and three other entrepreneurs founded Westjet on February 29th 1996. They had only three airplanes and five destinations and 220 employees‚ Beddoe believes that “Just because you pay less for your flight‚ doesn’t mean you should get less”. With this motto‚ Westjet becomes one of the lowest operating costs and the most successful airline company nowadays. In the early 1990s‚ the airline industry suffered a serious threat‚ caused by high fuel costs and a decline in air travel. At that
