beginning statement true and all statements along the path are executed, then the assertion at the end of the path is true. 4. If all paths in simulation are proven by induction, the model is proved to be correct.7. Introducing Mathematical Induction to M&S Engineering StudentsIn M&S, students should be utilizing probability distributions, such as the binomial, exponential,and beta, to name three. Proving probability distributions with mathematical induction is anatural introduction to the Formal V&V technique.For example, let the engineering student prove by induction on n that the binomial distribution: n b(k ; n, p ) =   p k q n−k , k = 0K

channels at a frequencysignificantly higher than the fundamental encoder frequency. In the case of the UC2system, the global clock is set at 11.0592 MHz which results in a maximum operationalspeed of over 300,000 rpm for a typical 512 slot codewheel. As illustrated in Figure 6, atwo-bit shift register employing D-type flipflops is used to detect transitions on channelsA and B.By way of example, a rising edge on channel A is detected when enc_dec0.q andenc_dec1.q are “1” and “0” respectively. The transitions between the various statesillustrated in Figure 5 can be decoded by analyzing the outputs of the four D-typeflipflops as shown in Table 1 below.State Transition Encoder Signals Flipflop outputs: enc_decX.q Past

analysis process. For any case, the first step in obtaining the wind loads is to determine the appropriatedynamic wind pressure. This pressure is obtained by treating the air as a perfect fluid and notingthat when wind strikes an object (a bluff body) in its path, the kinetic energy of the moving airparticles is converted to an effective dynamic wind pressure. This effective dynamic windpressure, q, at any height above ground is given by the following equation (Equation 6-13 inASCE 7):q z = 0.00256 K z K zt K d V 2 I (lb/ft2) (1)where,q = effective dynamic velocity pressure to be used in the appropriate equation to evaluate the effective static wind pressure for main wind-force

It should be noted that the display of gm for FETs wasnot available on either curve tracer directly from the instrument (βF was available only on the571). Thus the LabVIEW interface for the Tektronix 370 would not only provide the user withmore user-friendly interaction but additional capability for the FETs. A comprehensive user’smanual for the LabVIEW interface was another significant deliverable.After setting these design goals, a suitable LabVIEW GPIB driver that could be used as a startingpoint was downloaded from the National Instruments website (www.ni.com/devzone/idnet/).The project began late in the fall semester of 2002 with projected completion for student usage

Section3.6, the “clouds” represent the circuits used to implement the expressions. Again, the expressioncircuits are operated concurrently although only one computation result is routed to the output.3.8 Template for register In VHDL, memory elements can be inferred in various mechanisms and can be easily“embedded” in code. To enforce good design practice, our approach is to separate the memoryelements from the remaining circuit and describe them in explicit code segments. We use aprocess template, which is treated as a black box, to explicitly specify the desired D FFs orregisters. The VHDL code segment is : PROCESS(clk) BEGIN IF (clk'EVENT AND clk='1') THEN q <= d; END IF; END PROCESS

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

laboratory book 6 . The values of the resistors, RE (emitter resistor) and RC(collector resistor), were calculated and chosen in such a way that the direct current (DC)operating point known as quiescent (Q) point will lie in the middle of the load line. Having aQ point located in the middle of the load line is critical because under this condition, theamplified voltage signal will have no clipping (i.e. no distortion), even if the waveformengages in maximum positive and negative swings. The voltage gain ( AV ) of the C-Eamplifier (under no load) can be expressed as follows: RC AV = (1) ( RE - re ) where re = dynamic resistance, and the dynamic resistance can be calculated as VT (mV )re
