theirlearning is likely due to the fact that many exam problems are similar to these examples. It isalso noteworthy that the mean rating for overarching problems was significantly lower forMechanics II. This is likely attributed to the increased complexity of the overarching problemsin the second course, as described later in the section of this paper entitled Challenges. Table 5.

However, an interesting idea surfacedregarding the team status meetings with the instructor in which an interview Q&A style could beused to gather sufficient evidence.A pilot was conducted in spring 2010 involving the capstone for Electrical Engineering as wellas Computer Engineering majors. The face-to-face meetings with the teams provided anexcellent opportunity to evaluate the skill levels. The instructor reported that each teamemployed all 3 skills at one or more point(s) during the semester. The results are shown in Table5 for all 6 teams. Good performance was observed in 2-3 teams for each skill; however, the bestteams were not always the same. No team

coefficient (Cv) ratingof a valve is used by fluid power designers to calculate circuit flow, and compare one valvedesign against another as part of the sourcing decision. As such, it is important that a valvemanufacturer publish an accurate Cv rating in order to provide customers the needed applicationdata. The team determined that Cv accurately predicts flow (Q) or pressure drop (dp), using thespecific gravity (SG) of the fluid with expression9; √ . They also discovered thatvalve Cv is determined using a standard test protocol, FCI 68-2-1998, published by the FluidControls Institute3. The standard mandates that Cv must be determined using water (fluid) at60OF, and a valve pressure drop of one psid (bar). When valves are tested with water

Thesuperposition of all forces is applied to the robot, which, in most cases, is assumed to be apoint in the configuration space. Such an artificial potential field smoothly guides the robottoward the goal while simultaneously avoiding known obstacles. The basic idea behind thismethod is that the robot is attracted toward the goal, while being repulsed by the obstaclesthat are known in advance.The capsule could traverse the whole GI tract by implementing the above algorithm.

The TIMS-provided BPSK experiment was simplified to eliminate the phase shifter andline-code encoder, but still have a functional modulator that produces the expected BPSKwaveform. Instead of using an M-level encoder to generate I and Q data signals from a bitstream, as is done in a TIMS-provided experiment, a QPSK modulator is constructed inExperiment 6 using two independent data streams from the Sequence Generator module, eachmultiplies either a sine or cosine carrier, and the two modulated carriers are added. The use ofthe spectrum-analyzer capabilities built into the oscilloscope again allows students to view signalspectra. Students easily verify that the bandwidth of the BPSK signal with message data at
