IEs.The influence of computer technologies is not a new phenomenon in IE: Consider theperiod from the 1960's to the 1980's. It is interesting to observe that the use of computersnot only facilitated the solution of analytical models in this era, but also affected the typeof analytical models themselves, and solution approaches in a very profound manner.The mainframes were the workhorses for the pre-1980's, mostly running in a batchprocessing mode. (A program was submitted to the computer as one of many jobs.) This"batch job" paradigm is still visible in the models and methods of IE, and, consequently,many algorithmic procedures still follow the batch-job paradigm. Under this paradigm,the algorithm has a set of inputs. It then goes through a

. DEVELOPING SKILLS IN PROJECT DEVELOPMENT ABSTRACT By Lucian P. Fabiano New Jersey Institute of Technology INTRODUCTION Today’ s competitive need to develop high quality products has redefined the development role of engineers and engineering technologists . Historically, they have been hired to manage their own technical work activities and have not been expected to take on responsibilities required for overall project success. Today, engineers and engineering technologists assume much broader responsibilities . Responsibility for achieving specific

This acknowledged(’-s) course is a required,three-credit, first semester, capstone course for all senior mechanical engineering students. The course wasdesigned around the concept of providing our students with a taste of real mechanical engineering bychallenging them with small open-ended projects of industrial origin. The course focuses on defining andsolving problems of engineering value by experimental methods, integrating the necessary fundamentalprinciples learned in previous theoretical-oriented classes. Thus, the course is able to aide the mechanicalengineering student in bridging the gap between the abstractness of academia and the practicality of industry. The majority of

the time thatcan be devoted to this algebra practice. A simple method of partial fraction expansion, to check the studentswork or do the work for them, allows the students to learn more about how mathematical expressionsrepresent the circuits operation. In Matlab, the residue@,D) command provides a partial fraction expansion of a polynomial withnumerator, N, and denominator, D. For instance, consider a simple series RLC circuit with the output takenacross the capacitor. After transformation of this circuit into the Laplace domain and a few calculations,Equation [1] is found to represent the Laplace polynomial of the output of the circuit, where VO(S) is theoutput across the capacitor and VI(S) is the generalized input waveform.A common

Previous works in using MATLAB [16] in graduate level control systems, such as [3-4], have beenfocusing on the numerical solutions and simulation capabilities of MATLAB. In this section we will introduce,by way of several examples, some functions in the Symbolic Math toolbox that are useful in obtaininganalytical solutions to common control system problems. A typical problem in linear control is to obtain the transfer function matrix of a system given in statespace representation. If the system is given by i(t) = Ax(t)+ Bu(t) y(t) = Cx(t) +Du(t)where A, B, C, and D are constant matrices of appropriate dimensions, the transfer function matrix, H(s

Finally, outstanding issues will be mentioned.Motivating Factors and Long Term Goals Prior to this revision, the basic undergraduate EE program at Princeton had not changed forsome 30 years. In the late 80’s and early 90’s, several factors combined to lead the departmentto review its program. The first was the perceived changing nature of the incoming students.While equally as bright as their predecessors of 20 years ago, the students now seem to have lessof an inherent feel for engineering and less of an idea of what it is that engineers really do. Thishad led to a lower interest in course material, especially in introductory level courses. Whilethe first

Conference ProceedingsI. EVOLUTION OF ENGINEERING EDUCATION Engineering education objectives and methods have progressed greatly during the post-World War IItechnology boom. During the 1950's, teaching material was characterized by multitudes of design rules fordifferent practice scenarios, i.e. rules of thumb for particular engineering problems. It soon became evident that"cookbook" engineering was insufficient to meet the needs accompanying the rapid growths in new technologyand the ever-broadening scope of engineering problems. The emphasis of classroom education shifted in the1960's toward "engineering science," or the fundamentals of physical phenomena. This constituted an effort toinstill in students the necessary foundations for

thisalternate design process rest on powerful algorithms, developed by Simons and Harden to solve differential equations. [SIM088]These algorithms can be adapted to greatly reduce the number of computations required to derive a bilinear transformed digital H(z)model from a prototype H(s) analog model. This reduction in processing makes it feasible to base the optimal digital filter design onan analog prototype and arrive at solutions based on the changing coefficients of the analog filter. The end result is an optimallydesigned digital filter as well as an analog filter that could be claimed to be optimal in some sense. In order to verify and converge on a proper filter design, the frequency response of the current filter in the design process must

Inexamining the expanded utilization possibilities of engineering computer laboratories, though, other issues mustbe addressed before a strategy of implementation can be advocated. To explore the role of informationtechnology in the college classroom, we must more clearly define its missions in both the educationenvironment and the engineering workplace. We can then identify key areas that information technology andservices (IT&S), and specifically engineering computer laboratories, can assist in achieving these goals,supported by examples from the

properties with respect to their ability toextract solutes from complex matrices [Hawthorne and Miller, 1987]. The basis for predicting the volubility of a solute in a supercritical fluid solvent is the equivalence of fugacitiesfor the particular solute in each phase: (1)where the superscript s represents the solid phase and f the supercritical fluid phase. If the volubility of thesupercritical fluid in the solid phase is assumed negligible, then the fugacity of the solute in the solid phase, ~is, isequal to the fugacity of the pure solute, ~,s. The fugacity of the pure solute in the solute phase is evaluated using[Modell and Reid, 1983
