A bridge rectifier is a diamond-shaped configuration of diodes that serves to convert alternating current(AC) into direct current (DC). In our world of AC outlets and DC electronics, they are ubiquitous. Of course, most bridge rectifiers are built with regular diodes, not the light-emitting variety, because LEDs have a number of disadvantages. For…

Contribution: This paper has demonstrated that the use of blended learning in an electrical machines course has increased student engagement, pass rate, and scores across the GPA spectrum. Background: Lack of engagement by students in electric machine courses have been reported across the world. Interventions however, usually take the form of…

In this paper, a course on applied superconductivity is described. The course structure is outlined and the learning objectives and the learning activities are described. The teaching was multidisciplinary given by four departments each contributing with their expertise. Being applied superconductivity, the focus was on an application, which could…

The design of the drive system for an automatic machine and its correct sizing is a very important competence for an electrical or mechatronic engineer. This requires knowledge that crosses the fields of electrical engineering, electronics and mechanics, as well as the skill to choose commercial components based upon their technical documentation.…

This paper presents a low-cost hands-on experiment for a classical undergraduate controls course for non-electrical engineering majors. The setup consists of a small dc electrical motor attached to one of the ends of a light rod. The motor drives a 2-in propeller and allows the rod to swing. Angular position is measured by a potentiometer attached…

This paper describes the goals, pedagogical system, and educational outcomes of a three-semester curriculum in microelectromechanical systems (MEMS). The sequence takes engineering students with no formal MEMS training and gives them the skills to participate in cutting-edge MEMS research and development. The evolution of the curriculum from…

The Internet provides an opportunity for students to access laboratories from outside the campus. This paper presents a Web-based remote access real-time laboratory using SCADA (supervisory control and data acquisition) control. The control of an induction motor is used as an example to demonstrate the effectiveness of this remote laboratory,…

As part of a study of the application of communication satellites to educational development, certain technical aspects of such a system were examined. A current controlled bistable switching element using a CW Gunn diode is reported on here. With modest circuits switching rates of the order of 10 MHz have been obtained. Switching is initiated by…

The terms in this glossary come from the fields of electronics, communications, systems analysis, mathematics, and computer science. When two or more terms have the same meaning, the preferred term is noted. Relationships between terms are shown by descriptive cross-referencing expressions (i.e., similar to, contrasted with, related to, clarified…

An analysis of tasks performed by electronic draftsmen with implications for educational needs. (GB)

Discusses the need and usefulness of defining electromotive force, potential difference, and voltage in a precise way so that each can be distinguished from the other. (SL)

The microcomputer troubleshooter is regarded as a technically knowledgeable member of the team and is more active in equipment selection, site preparation, site supervision and preventive maintenance, and on-site training of operators, maintenance people, and programmers. Microcomputer troubleshooting can be incorporated into an electronics…

The manual is designed as a self-study text for use by personnel of the Navy and Naval Reserve who are preparing to meet professional requirements for advancement in the rating of Aviation Electronics Technician. The document opens with a review of leadership and qualifications for the Aviation Electronics Technician rating. Other chapters cover…

The State Technical Institute at Memphis, Tennessee, is part of a nationwide group of postsecondary institutions that are contracted to provide technical instructor services to Naval personnel. (SK)

Presents the plans for constructing a spectrophotometer which can scan the spectrum in a thirtieth of a second. The instrument can be used to determine the absorption characteristics of a solution compared to a pure solvent. The instrument allows time to investigate phenomena that occur quickly. (Author/SA)
