Each of the three phase converters can be usedto control a DC machine when only two of the three power-poles are used or a three-phase ACmachine when all the three poles are used.

illustrate to undergraduatestudents the concept of nonuniform convergence of successive partial sums over the intervalfrom 0 to B.1. Introduction Gibbs Phenomenon is intimately related to the study of Fourier series. When a periodic functionf(x) with a jump discontinuity is represented using a Fourier series, for example, it is observedthat calculating values of that function using a truncated series leads to results that oscillate nearthe discontinuity [12]. As one includes more and more terms into the series, the oscillationspersist but they move closer and closer to the discontinuity itself. Indeed, it is found that theseries representation yields an overshoot at the jump, a value that is consistently larger inmagnitude than that of the actual

of the BOK as shown in theframe below. The BOK could be fulfilled by obtaining a Bachelor’s degree plus either aMaster’s or approximately 30 acceptable credits and experience (“B + M/30 & E”). The“E” in “B + M/30 & E” refers to progressive, structured engineering experience which,when combined with the educational requirements, results in attainment of the requisiteBody of Knowledge. “B + M/30” represents two different (B + M and B + 30), butrelated methods to satisfy the formal educational requirements for entry into theprofessional practice of civil engineering. Both are equally satisfactory in fulfilling theBOK requirements. The two paths are diagramed below and will be described in thefollowing paragraphs

Course content ofboth courses will be discussed as well as the philosophy of placement of various topics inthe two-course sequence.Introduction:The two-course sequence is designed to challenge PLC students and provide more well-prepared students for the manufacturing environment. The challenge requires moreprogramming than may be presently taught in a more traditional PLC course.[1-9]The first course concentrates on programming the PLC. A choice must be made for thePLC manufacturer and Allen-Bradley (A-B) was chosen. Any course should

use the program to check every single step of the calculation.The following sections describe three phase circuits, the developed program, some examples andfinally a conclusion.Overview of Three Phase CircuitsThe three-phase circuit is composed of a three-phase system of voltages connected to a three-phase load configuration. If the voltages have the same magnitude and frequency and eachvoltage is 120° out of phase with the other voltages, the voltages are said to be balanced. Inaddition, if the loads are configured in a way that the resulting currents are balanced, then theresult is a balanced three-phase circuit [1-5].In a three-phase circuit, the voltages are connected to the corresponding loads by lines a, b and c

A thorough discussion ofstructured design would include topics of “divide-and-conquer” techniques, structure charts,UML activity diagrams, implementation and testing techniques, and thorough systemdocumentation procedures [10].

The need to convert most variable names to cell addresses in the model equations. 2. The necessity to provide separate documentation to the model equations. 3. The lack of tools for easily solving differential equations.Recently we have enhanced the Polymath (copyrighted by M. Shacham, M. B.
