, “Communications Measurement Laboratory.” This new course was designed to reinforce student knowledge of their course work in signals and systems, digital and analog communication systems, and digital signal processing. The primary course objectives were to familiarize students with vector signal analysis and develop a thorough understanding of I and Q-based demodulation techniques. This paper provides an overview of this course and describes student projects that utilize a vector signal analyzer (VSA) to detect, localize, and record decimated I and Q data as would be available at the output of an intermediate frequency (IF) analog-to-digital converter (ADC) stage of a software defined radio (SDR).1 IntroductionThe

These differences reflect many local influences such as theundergraduate curriculum, individuals teaching at these institutions, and the types of industry inthe region. Relevant to this paper is classifying the different structures of design classes acrossthe nation.Lovas identified several levels at which senior design classes can be taught: the engineeringschool level, the engineering program level, and the engineering stem level.

And two decades later, Jordan had its first college of engineering in its capital,Amman. The colleges in Lebanon and Syria paralleled, by and large, the French schools ofengineering; except for the American University of Beirut (AUB), typically a North Americanschool, looked after by a consortium representing colleges on the East Coast of the USA.Colleges in Egypt and Iraq were influenced, at the time of their establishment, by the Britishsystem of education.1, 2 , 3Engineering education in the Arab Gulf States started, in earnest, during the early to mid sixties.Initially, colleges of

the power stroke. For a simple case of constant angular acceleration, andassuming that acceleration starts from the same initial angular velocity for each cylinder (say atω0), as shown below, power generated by a cylinder is proportional to the square of the increasein the engine speed. In real life, angular acceleration is not constant since torque is not constant.Nevertheless, square of the change in the engine speed is an indication of relative cylinder power.For a constant angular acceleration, the governing equations are:ω2 = ω02 + 2*ω*(θ-θ0) (1)T = I*α (2)ΔP = T*(Δω) (3)Substituting equation (1) into equation (2) and usingω2 = (ω0 + Δω)2 ≈ ω02

Schoenfeld discussesresources mainly in terms of conceptual or cognitive resources.1 For our analysis we adopt abroader notion of resources by also including the students’ material and social resources. Thisunderstanding of resources closely resembles the definition of resources McGinn and Boote usedfor their study of problem solving15. Two of the main resources available to the students weretools (mainly a material resource) and experts, such as instructors or graduate students in thedepartment (social resources).

The studentperformance and course evaluations in parallel sections of the course were tracked overseveral semesters. The findings indicate that learning effectiveness in an online coursecan be just as good as in a traditional course.1. IntroductionThe traditional approach to higher education involves a cohort of students comingtogether at a specified time and location in a formal classroom setting to meet with aninstructor. Students typically learn in a lecture format in which the students are mostlypassive recipients of knowledge disseminated by the ‘expert’ instructor. The emergenceof new educational technologies

Inclass-D amplifiers, the sinusoidal reference waveform is replaced with a low-power audiosignal, and the filtered PWM output of the inverter becomes the amplified audio signal.The energy-savings aspect of class-D amplification has long been known and has beenwell documented [3]. In class-D amplification, an audio signal is converted to a pulse-width modulated voltage that changes between two levels. Power losses are mainly dueto imperfect switching in the transistors during voltage transitions. Most audio amplifiersuse the well-known class AB amplification method. The

Few courses are offeredthat are at the discretion of the student to enhance their personal growth; therefore, there is littleemphasis placed on measuring the impact a course may have on a student’s cognitive orbehavioral growth. Wilde stated in 1983 that, “The route from school direct to university for anengineering degree without practical experience in the industrial environment does not give theyoung engineer the basic skills, knowledge or attitude required for a career in engineeringdesign.”1 A common practice in engineering curriculum at most higher education institutions isthe use of simulations or design projects to give students hands-on and real-world experiencewith the objective of not only

In response, many engineering schools are developing full-semester study abroad options. Perhaps the US university most active in overseas education isGeorgia Tech, which has grown their international programs over the past seven years into a setof 22 programs, involving more than 750 students, representing more than a third of their annualundergraduate degrees awarded.1 Many of these students study at the permanent GT Lorrainecampus, where 76% of the participating undergraduate students are in engineering disciplines.The International Engineering Program at the University of Rhode Island is essentially
