between work and heat is that work can always be converted completely to heat but that only a fraction of work can ever be transferred to heat. For that reason alone, we can argue that of the two forms, work is the “higher value” form of energy transfer. More on this with the second law introduction later. So taking B as Energy in our Reynolds Transport Equation we can write the First law of Thermodynamics so :- Q% / W% - (m% e) in / (m% e) out - E% gen ?

The courseevaluation is a set of eighteen questions that students answer using an agreement scale (5=strongly agree, 4= agree, 3=neutral, 2= disagree, 1= strongly disagree). These questions aregrouped into six categories. Four of the eighteen questions and two of the six categories wereused to assess students’ satisfaction with the course and, specifically, the RGM project. Theresults per year are presented in Table 2. Table 2: Results of the project assessment using mean scores of course evaluations. First Three RGM Question (Q) / Category (C

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

formulated and solved by linear programming [6].• Inventory Models. An objective of the economic lot size model is to define an inventorymanagement policy of minimum cost. As suggested by the parameters “Q” and “t” in Figure 2,the inventory manager is interested in determining “How much?” and “When?” certain stockedmaterial should be replenished. In general, the optimal inventory level is dependent on customerdemand, while the costs of producing and holding inventory are balanced off against oneanother. The cost impact of inventory shortfalls (shortages) adds a further degree of complexityto the model. Page 9.521.3 Proceedings of the 2004

magnitude of the voltage or electrical “pressure” supplied to the circuit is analogous to thewater level in TANK A. The adjustable gate valve that meters the flow of water and reduces thepressure on the downstream side represents the resistor in the circuit, R. The on/off switch is thesolenoid valve, and the empty tank, TANK B, is the capacitor (uncharged or empty) prior tofilling. The electrical current flowing through the circuit, i, is simply the water flowing throughthe pipe.So the valve setting (or magnitude of resistance R and the tank diameter or capacitance, C bothinfluence the charging (or filling) rate of the capacitor. Recall that a capacitor stores andelectrical charge, q given by the equation, Q = CV where Q is the total charge across

Data was randomly generated, based on the stored problemspecific parameters, and displayed along with summary statistics (see Figure 2 for a depiction).After digesting the sampled data, the student could (1) request more data, (2) enter a solution, or (3)exit the system to return later.

This program can be run as an interactive program or on a batch mode viaan input file.

ceiling at42,950 feet (i.e., when specific excess power equals 100 feet per minute).A velocity versus load factor (V-n) diagram was constructed using the calculated stall velocity,given load limits5, and the calculated dynamic pressure (q) limit. At sea level, the q limit isdefined as the dynamic pressure corresponding to the maximum level velocity where thrustavailable equals the thrust required. This value of dynamic pressure is used at other altitudes anddensities to solve for the corresponding Mach number. The data indicates a similar method wasused to obtain the q limit of the published data. The calculated T-38 V-n diagrams for sea leveland 15,000 feet are shown in Figure 6. Proceedings of the
