However, it will be proved in this paper that, even if suchinformation is not available, under quite general conditions Richardson extrapolation willimprove the accuracy of the numerical result (or, at the very least, maintain the accuracy).The following material is a brief description of Richardson extrapolation. Let q denote anunknown exact quantity that is desired. Let q1 and q 2 denote numerical approximations to qthat are computed using the same formula (and at the same grid point) but with different,sufficiently small positive grid spacings, h1 and h2 , respectively. If the dominant term in thediscretization error is proportional to h p , for some positive number p , then we

The analysis results in formulas for temperaturedistribution, the rate of heat exchange with the surrounding environment, and the fin efficiency.Boundary conditions used in the analysis will influence the resulting equations. For example, foran infinitely long fin of a uniform cross-sectional area the temperature distribution and heattransfer are given by the following equations.

It wasin this manner that counters, conditionals, and loops were introduced. The syntax of thecommands was agreed upon by the students and the only requirements were that the commandsmust be elementary and non-ambiguous. The students were presented with problems that couldnot be solved using a single S robot and asked to find the minimum number of such machinesthat were required to solve the problem. Then Q robots were introduced – pick from front ofdeck, put down at end of deck. More complicated problems were assigned and the groupspresented a variety of

Utilizing polymers with gas specific qualities, it is possible tocalibrate the MEMS resonator for gas detection purposes such that the concentrations can bedetermined. The process of absorption is a temperature dependent reaction, therefore control ormonitoring of the device temperature is important.For the gas sensing to be effective, the resonance should be well defined with a high “QualityFactor, Q” at atmospheric pressure. “Quality Factor” is defined as the ratio of the
