This problemcan be solved by placing the poles of the compensated system at certain locations using full statefeedback. The procedure for solving this problem using MATLAB is described in the following.1. Assume that A, B, C, and D matrices of (1) were created in MATLAB

The phone solid was created fromthe geometry by using solid loft, solid extrusions, solid Boolean operations (intersection,subtraction) and corner filleting in the GibbsCAM [3]. Three segments slightly shown inFigure 2.a were used to generate the phone model. Figure 2.a also shows the finished solidmodeling. Page 10.1219.3 Proceedings

of interfaces is a matter ofconcern for software developers, and might be a barrier in solid modeling education and inengineering practice7. This is because it is believed that the layout of GUI elements influencesthe way users can interpret these elements8. While the user’s correct mental model of theinterface can help with their productivity, a false image of the interface might mislead them andlimit their ability to work with the software effectively9. For example, a recent experimentalstudy showed that, if an unknown icon A in software 1 looked like a well-known icon B insoftware 2, the users supposed that the icon A represented the same function as the icon B, evenif both pieces of software were quite different10. Therefore, it is clear

As a result the majority of theteams that designed the posters did not get instant feedback because they were unable tostand by their posters and defend their designs. If they were able to

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

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

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
