detailedrubrics. The grades in these models are not purely percentage or points and rather are labeled withspecific levels of understanding. But in order to ensure students the best opportunity to achievethose competencies (which translate later into a letter grade), it is critical to (a) give strongfeedback and (b) allow students to attempt a particular learning objective more than once. Thisrepetition could be repeating the same concept in different ways or revisiting the originalquestion/assessment with a different approach and more guidance.This feedback cycle could be viewed as an impediment to widespread implementation ofcompetency-based grading, as it requires instructors to have multiple assessments and provide fastand specific feedback.

moreindependent processors into a single package, which is capable of executing multiplethreads simultaneously. The L2 cache on a multicore processor can be either private orshared, as depicted in Figure 1 (a) and (b), respectively. Clearly, multicore processors cannaturally benefit multithreaded programs by running them on different cores concurrentlyto improve the throughput. However, unlike other advances of microprocessors aiming atthe transparent increase of single-threaded performance (e.g., frequency scaling, pipelines,caches, and superscalar architectures), multicore processors cannot automatically reducethe latency of single-threaded programs. In many cases, there is no way to effectivelyutilize the performance of additional processor cores or

The hour counter counts 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and repeats. Oneway to design the clock is to break it up into smaller parts as shown in Figure 3 below.

here.The questions given to the IEEE club are given below. Note that the “a” questions (1a, 2a, etc.)are “generic” to courses (and associated labs), while the corresponding “b” questions (1b, 2b,etc.) are specific to the big_blinky lab/tutorial. Very similar “a” questions were used for the EGR101 students, except modified to refer to “this course” instead of “my courses”, and using“engineering” instead of “ECE”. But the “b” questions were identical.1a. The lab work I do for my courses is relevant to my learning.1b. The big_blinky lab/tutorial was relevant to my learning.2a.

Next to the sensor is a vertical array of LEDs. Further down the track are twoswinging gates connected to separate servo motors. The servo motors are be operated to openand close the respective gates. Across from each gate is a proximity detector which can be usedto detect objects that pass in front of the detector.

In addition, this project includes the design and fabrication of a sleek, carbon fibercomposite body, which is used in construction of many modern unmanned vehicles. Thedevelopment of this vehicle utilizes the knowledge gained from many aspects of theundergraduate engineering degree while adding more capability to the open source unmannedsystem community. The project was performed by an undergraduate engineering student whowas mentored and supervised by two faculty members.2.

Reference 6 has suggested topics usingtransmission lines first approach and also uses MATLAB examples.It is true for students as well as for some ECE faculty that the subject of electromagneticsis possibly the toughest mathematically oriented subject in the undergraduate curriculumfor electrical engineering and some computer engineering majors. Basically there arefour (4) major equations, MAXWELL’S EQUATIONS, which govern the behavior oftime-varying (dynamic) electromagnetic fields and wave propagation. In most commonform these equations are stated as:ı · E = - • B/ • t ; ı · H = J + • D/ • t ; ı· D = t ; ı ·B=0where t is volume

The softwareincludes computation, viewing, and programming in a user-friendly environment. AlthoughMATLAB has a user-friendly graphical user interface (GUI) interface, its functions are primarilyexecuted through commands. Therefore, the user must know these commands and the syntax ofthe programming language. Common uses of MATLAB include: a) plotting of complexmathematical equations, b) mathematical computations, c) algorithm development, and d)modeling and simulation.SIMULINK has an interactive environment that facilitates
assignment is labeled as a performance indicator for a particular Course Objective orProgram Outcome. A 70% score on the assignment is determined to be the minimum level of Page 12.1281.5achievement for the indicator. Ten students in Class A and ten students in Class B complete theassignment. In both classes, 60% of the students achieved a score of at least 70% on theassignment. In Class A, the class average on the assignment is 72%, while in Class B, the classaverage is 54%. How shall these results best be interpreted?The answer, of course, depends on the individual program and its use of the assessment data.The following examples highlight how

The Avg Class Grade/4.0 column represents theaverage grade in ECE300 for all students in that group out of a 4.0 scale with 4.0=A, 3.5=B+,3.0=B, 2.5=C+, 2.0=C, 1.5=D+, 1.0=D, 0.0=F, and 0.0=Withdraw.The benchmark to which all changes are compared is the original version of ECE300 (first rowof Table III), for which 8 years’ worth of data is reported. Even though the subset of questionschanged between groups, this group was used as the basis of comparison in order to have a largerdata set. Furthermore, because the normalized gain is being used as the measure of performance,the impact of the different subsets is somewhat lessened.The

First attach the PCB to the power supply a. Assure that the hot and ground wires are attached correctly, with one other member verifying a proper connection to avoid destroying the PCB. b. Turn on the power supply and set slightly above 9V. c. Check for power LCD on PCB if present, good. If no power LCD turn off immediately. 2. The next step is to open an AVR Studio 4 project. a. Select and open AVR Studio. b. Once opened click the “New Project” button to open a new project. i. Next select the “AVR GCC” and name

an FPGA device such as dig-ital clock management, phase lock loops, and soft core processors are more valuable. W sug-gest that an FPGA device is preferable and more flexible. Concise, optimized logic can still betaught by setting appropriate assignment constraints while using a more flexible FPGA. b) Compatibility with vendor design software As an example, the Spartan 6 was used in the design of OwlBoard. The software used toprogram Spartan 6 devices, ISE, was deprecated by Xilinx at version 14.7 in October 2013.Spartan 7 devices were not yet available in a surface mount package during design of the Owl-Board. While this does not seem like a major problem, note that Xilinx ISE 14.7 does notsupport SystemVerilog. Also note that the design
