These expressions may contain mathematical functions, symbols, parameters, numbers, units or any combination of them. For those of you who are writing your thesis, here are some brief guidelines on how to write these mathematical expressions Keep in mind that your discipline may have slightly different or additional requirements, so always doublecheck with your supervisor.
The "best" fit after the ith iteration is obtained by using the following equations.
However, numerical experiments indicate that good convergence may be obtained even if the initial guess is off considerably. These numerical experiments show that the initial guesses for T and S may be overestimated or underestimated by about two or three orders of magnitude.
These experiments covered the normal range of T and S encountered in groundwater work. It is possible to obtain an initial guess for T and S from the data if reasonable values are not known.
At some time t0, the drawdown predicted by equation 31 will be zero. The method of least squares is ideally suited to this problem. Obviously, at least two drawdown-time pairs are needed to define a straight line.
If more than two pairs are given, the least squares technique finds the "best" fit. In this work, the last four drawdown-time pairs are used to make an estimate of T and S if reasonable values are not known.
If this condition is not met, then this procedure will probably not provide an acceptable guess for T and S.
Let se t represent the experimental data. This procedure works well if the restrictions on r and t are observed. The gal-day-foot system or any consistent set of units may be used. Figure 1 is a printout of a typical run. The program initiates a series of questions after the RUN command is typed and a carriage return is given.
A carriage return is required after each response. The first question asks if the user wants u, W, and the sensitivity coefficients printed. In Figure 1, the extra printout was requested.
The second question defines the system of units. The user can use the gal-day-foot system or any consistent set of units. A YES response, as in Figure 1, means the gal-day-foot system is being used.Standard friction equation.
The standard equation for determining the resistive force of friction when trying to move two objects or materials with respect to each other shows the relationship between the force of friction, the coefficient friction, and the normal force pushing the two objects together.

Find an equation for the line with the given properties. Express the answer using the slope-intercept form of the equation of a line.
The chosen TeX Gyre Heros is the font not only without serifs, but also has heavier weight compared to Charter — this results in a good visual separation of the headings from the rest text making TeX Gyre Heros a good companion for the body text typeset with Charter.
One can say that the career of Albert Einstein started in , when he was granted a teaching diploma by ETH school in Zurich.
Einstein there wrote his first published paper, titled "Consequences of the observations of capillarity phenomena”. Compose a draft thesis statement. If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or "working" thesis statement.
