Thesequizzes are useful because each student will see a different set of numbers for each question.In addition, these quizzes can be set up as adaptively graded. Adaptive grading is thededuction of a certain percentage for each answer attempt. Below, is an example of aquestion from both the faculty as well as student’s perspective.Faculty PerspectiveFigure 1 shows an example taken from my fluids course for Spring 2012.

the electromagnetic immunity of digital ICs could help the IC designer build betterICs and help the board designer build better systems that use these ICs, but unfortunately suchmodels are not widely available. A test IC containing components common to all digital ICs wasbuilt to help develop immunity modeling strategies (Figure 1). One component in test IC is anSRAM circuit, which requires many digital signals to properly read and write values frommemory. A method was needed for generating and reading the digital signals to and from theFPGA at high speeds. Digital signals were generated with a Cyclone III FPGA developmentboard with an external clock speed of 50 MHz. The switching frequency of the signals had to bearound 400 MHz, which is

To compound the issue, instructors in the “hard” disciplines deal with instructional 2material that lends itself to a more “teacher-centered” approach to learning where transmission ofinformation and worked examples are the highest goal.1 However, some research studies havefound that this approach is linked more to surface learning. Deeper learning has been linked to amore “student-focused/conceptual change” approach, more regularly seen with instructors in thehumanities and soft sciences. 2At a land-grant, research-intensive

well at low frequencies [1]. Optimization of the antenna design would force a compromise between frequency bandwidth (range resolution) and angular resolution. The upper bound of this frequency band was limited by the available instrumentation (a vector network analyzer), and the lower bound was limited by the size of the antenna. The frequency band of 1 - 6 GHz was chosen as an optimal solution to the requirements. This frequency band also achieved the acceptable compromise between the required resolution and penetration depth due to the size limitations of the array. Once the operating points of the antenna array were determined, a suitable antenna design was sought. In this case, a Vivaldi antenna design (an endfire, tapered-slot

While this design provided a reduction in dragcompared to fuselages with a non-circular frontal area, there were some issues with the design.A full-walled cylindrical tube made access to the various electronics in the front of the aircraftdifficult. Attaching the wing and landing gear to the fuselage also became difficult due to thelack of flat surfaces. This issue will be discussed further in the landing gear section.

In addition, video produced in previoussemesters are available to students currently enrolled in the class in an asynchronous manner tohelp to reinforce key concepts on an as needed basis. This project addresses four focus areas, namely 1) enhance student professionaldevelopment, 2) increase faculty-student interaction, 3) promote active learning and 4) improveattainment of learning outcomes.

The current is then directed through theconducting rod to a spherical load which will discharge electromotive forces after reaching aparticular electrical surface charge density. A similar device is used as the receiver. The receiverconsists of coils which mirror those of the transmitter and its pancake shape. The receiver isconnected to devices such as a motor or light through its primary coil that will then make use ofthe received current.
