50 The programs have shortcut functions that are used to calculate: nt(E), pt(E), LINT and Lx (LINT is an integral required to find Us, Lx is the function within the integral); the functions are just computational shortcuts and do not affect the Idea behind the method. In short, the method calculates an array of all possible Qo(i) values, and, by a simple value by value search, finds the smallest Qo(i), and the phi_s(i) that corresponds to that Qo(i), then from that, it calculates Us, Se (Seff) Inputs: for n and p type: output file name: eight characters maximum, no extension the program creates two files with a .txt and a .pm extension the .prn is comma delineated and can be read by Excel and Mathcad delta _n 10^x range: enter x, y (with the comma) where, x is the 10^x of the lowest delta _n and y is the 10^y of the highest delta_n Qf, Dit, vth: enter x.xxxxeyy, x.xxxxeyy, x.xxxxeyy (with the commas) note the eyy is how the program understands scientific notation where eyy = 10^yy
