wasfound that almost no one took advantage of the late homework policy, and instead would just notturn in the homework at all if they knew it would be late.Accumulation of points on tests, homework, in-class activities, and other assignments allowedstudents to obtain grades better than C−. The final grade breakdown based on how many points astudent earned is shown in Table 2. A grade of D or F was only given if a student did not pass allten mastery topics during the semester. Table 2.

operation11, the two streams can be treated as two frames aligned in verticallayers. The top layer and bottom layer are known as a foreground frame and a backgroundframe, respectively. We consider three blending schemes and a video core can select a schemethat fits its need. Let f and b be the colors of the foreground pixel and background pixel and let rbe the blended result. The formula for the three schemes are • Multiplexing: r = α*f + (1 - α)*b where α = 0 or 1 • Alpha blending: r = α*f + (1- α)*b where 0.0 ≤ α ≤ 1.0 , • Chroma-key blending: , The multiplexing scheme treats the streams as two independent video sources and selects onesource and routes it to
: Implementing Sophomore Cornerstone Courses in Electrical and Computer EngineeringMany engineering programs have significant project- and design-based courses in the freshmanand senior years. Freshman courses usually serve a dual purpose: a) making engineering a moreattractive study option for undecided students, and b) introducing the basics of technical andnon-technical skills, such as teamwork and project planning. On the other hand, seniors doingtheir capstone projects are expected to perform at a more proficient level, one that woulddemonstrate their readiness for entering the workforce as engineers.As will be discussed below, the project component in our freshman year-long sequence evolvesfrom minimally structured projects

project evolved from a System Requirements Review to the Preliminary,Critical, and Final Design Reviews. This senior design project was especially notable for three factors:(a) the emphasis on an early implementation which facilitated multiple passes along the design spiral, (b)the close synergy between the evolution of the hardware and the simulation models, and (c) theinter-disciplinary nature of the design which provided opportunities for electrical engineers to consideritems such as material properties, forces on the barrel, temperature effects, aerodynamic drag, railablation, and velocity measurements. In the process of the design, students were able to leverage theircircuit analysis skills and build on their simulation experience in both

involved in using continually-evolving system-level design tools and theefforts made to reduce their learning times.IntroductionABET 2000 requires providing students with a significant hands-on design experience.Graduating electrical engineering students should have the ability to develop system-leveldesigns for a variety of applications, implement these designs in functional hardware, and test thehardware in real-life operating conditions. To achieve such professional competence, studentsshould be required to participate in a sequence of hardware design experiments and projects.These laboratory exercises aim at: a) sharpening students’ abilities to design complex digitalcircuits and systems, and to interface these designs to peripheral devices, b
defines the transmitted waveforms anddemodulates the received waveforms. Software radio has led the trend in the wirelesscommunication arena to design and build wireless communication systems using reconfigurablesoftware rather than fixed hardware. We see this as an opportunity for STEM educationinnovation by bringing in this new technology within a limited budget. Figure 2. (a) USRP software radio board; (b) Current teaching lab setup.At Wright State University, in the past several years, we have experimented in our undergraduatewireless communication course (EE421) with off-the-shelf Universal Software Radio Peripheral(USRP) boards7 that support GNU software radio8 for course laboratories.

For example, according to oursurveys, individuals with physical disabilities who are confined to a wheelchair may experiencelower self-esteem and self-acceptance, and greater social isolation than those without disabilities[3-8]. To address this problem, a group of senior students from mechanical, computer andelectrical engineering disciplines developed a wheelchair which has the following features: a) theseat on the wheelchair can be raised, allowing the user to bring himself to the same eye level of astanding person; b) the seat rotates about its axis allowing the user to address persons on his sidewithout the need to move the whole chair; and c) the seat is mounted at the end of an arm whichcan be rotated, maintaining balance by outriggers
and thepower rails for the amplifier. We again note that many non-major (as well as freshmen major)students quite often forget to power the amplifier in the laboratory. This is a very typical mistakethat should be explained in class from the very beginning of the amplifier topic. The samestrategy is applicable to a push-pull transistor amplifier.Fig. 1. Current flow in a non-inverting amplifier operating in a) push mode, and b) pull mode.The path of the load current is marked in bold. The same concept applies to the push-pulltransistor amplifiers (when studied in class). Page 15.1048.33. Basic semiconductor (diode) theory - is it difficult

Consequently,the students were split into 3 groups of 6 students, and each of the 3 groups was provided a singlemultiuser transmitter to share among the 6 students. Within each group of 6 students, the studentswere asked to form pairs, with each pair of students constituting a team. This partition is shown inFig. 3.

Thealuminum contacts are then defined using a final photolithography process in which all of thealuminum is removed expect for the contact pads over the contact windows. The devices arethen ready for testing.TestingFrom the beginning it was expected that testing these devices would present the greatestchallenge. Testing required us to overcome three major challenges: create a low noiseenvironment, create the strong B-field required to generate the Hall Voltage, and increase thecurrent flow through the Hall Effect device

Page 25.648.6 b) Then add a four tile sprite that moves from left to right across the middle of the screen. c) Next, change the program such that the sprite moves diagonally across the screen. The sprite must reappear on the opposite edge if it moves off the screen. The speed of the movement can be fixed and dependent upon delays placed in the program since the program need not perform other operations. d) Make the sprite “bounce” at screen boundaries or for an added challenge use the collision detection features to make the sprite

Side “A” is filled with a specific gas. Side “B” is atheoretically perfect vacuum. Once a portion of the divider is removed, the molecules on side A will tendto move towards the area of lower concentration (side B).
