(1c)The relationship (1a) corresponds to that of a resistor or equivalent; the relationship (1b)corresponds to that of an inductor or equivalent; and the relationship (1c) corresponds to that ofa capacitor or equivalent. These relationships are not required in the statement of the extendedTellegen’s theorem that we propose. However, they are required in the analysis. The analysismay be carried out either in the time-domain or in the Laplace transform domain. The Laplacetransform domain equations corresponding to Eqs. (1a), (1b) and (1c) are given below: Av(s) = k1 . Tv(s) (2a) Av(s) = (sk2) . Tv(s

application ofthe proposed algorithm.II. Formulation of AlgorithmConsider two polynomials in s, N(s) and D(s) over a field, given by: N(s) = ansn + an-1sn-1 + an-2sn-2 + . . . +a , 0 and (1) D(s) = bdsd + bd-1sd-1 + bd-2sd-2 + . . . +d 0Where d > or = n. D(s) = Q(s)N(s) + R(s). (2)It can be shown that the quotient polynomial Q(s) is of the form: Q(s) = bdsd-n/an + {c1sd-n-1 + c2sd-n-2 + ... + cd-n} (3)and the remainder polynomial R(s) is given by: R(s) = r1s n-1 + r2sn-2 + . . . + rn (4)A tableau can be constructed from
accomplishing that outcome. Finally, again as othershave done, the committees went the extra step of requiring course chairs to develop sub-outcomes (e.g., course outcomes) that give explicit guidance to faculty about specific results thatare required in individual courses if the broader program outcome(s) are to be achieved. It isthese course outcomes that have taken on a central role in the quality control process.Course Outcomes In identifying course outcomes, the intent of the curriculum committees was to create a setof clear metrics by which course successes could be judged. Thus, it was essential that courseoutcomes be stated in clear terms and in a way that lent them to objective measurement. To thatend, course chairs were charged with

principal benefitsattributable to service-learning (S-L) dispersed through core required courses through surveys,interviews, and focus groups. As S-L continues to become a significant part of the community-engagement movement in higher education, and as more university professors are encouraged toincorporate S-L activities in their course requirements, it is essential that educators build anunderstanding of what students gain with S-L and that they give students a voice in their owneducational process and in the community. The service-learning (S-L) program SLICE (Service-Learning Integrated throughout a College of Engineering), based within the Francis College ofEngineering at the University of Massachusetts Lowell, began as a curricular reform

allows the student to view both root locus andBode information. Unlike the GUI in this paper, the built in design tools are not based on theunified design procedures of the author’s previous work.9,10 Consequently, it does not providethe same seamless integration for the students as they transition from simple classroom exercisesto more complicated lab and design projects.Compensator DesignThe integrated design procedure using time or frequency domain plant data requires ageneralization of the angle criterion from root locus design. The standard closed-loop system isshown in Figure 1 where K is the control gain, Gc (s) is the compensator and G p ( s ) representsthe plant dynamics. R ( s
plant transfer function Gp(s) had to be easily isolated for open looptests, and the ability to close the loop had to also be included.Derivation of the CircuitThe basis for the simulator lies in the fact that differential equations can be solved/simulatedusing an analog computer. Using this fact, a circuit for simulating type 0 and type 1 systems canbe derived.For a type 0 system, Gp(s) = k/(s^2 + a s + b)Since Gp(s) represents the output Y(s) divided by the input R(s), Y(s)/R(s) = k/(s^2 + a s +b)or Y(s) (s^2 + a s +b) = k R(s)Taking the inverse Laplace transform, y’’(t) + a y’(t) + b y(t) = k r(t)or y’’(t) = k r(t) – a y’(t) – b y(t)This differential equation is simulated using the analog circuitry shown in

mechanical systems. Then, students will solve them by using a directmethod in the real domain and by applying the transform methods either in the frequency domain(Phasor Transform) or in the complex s-domain (Laplace Transform). Since the application oftransform techniques is much quicker and more efficient, especially when a real system carriesthe initial condition(s) or boundary conditions, we will focus on the Phasor Transform todetermine the steady-state response for an AC circuit and the Laplace Transform to derive thecomplete system solution, which includes transient and steady-state responses for both electricaland mechanical models.
