A three-dimensional heat transfer model is built according to the rotor structure of an asynchronous motor, and three-dimensional temperature fields of the rotor under different working conditions, such as the unloaded, rated loaded and that with broken rotor bars, are studied based on the finite element numerical method and experiments. The…

This paper presents several methods for motivating students taking a power system protection (PSP) course. The paper reviews the laboratory activities developed for the PSP course at Curtin University, Australia; these methods are applicable and can be used for PSP course instruction at any institution. These activities were developed to improve…

Adjustable-speed drives based on multiphase motors are of significant interest for safety-critical applications that necessitate wide fault-tolerant capabilities and high system reliability. Although multiphase machines are based on the same conceptual theory as three-phase machines, most undergraduate electrical machines and electric drives…

This paper discusses the situation in a 3-phase motor or any other 3-phase system operating under unbalanced operating conditions caused by an open fault in an inverter switch. A dc voltage source is assumed as the input to the inverter, and under faulty conditions of the inverter switch, the actual voltage applied between the line to neutral…

The exilic mode of being, a living on boundary-lines, produces a constant relativization of one's home, one's culture, one's language, and one's self, through the acknowledgement of otherness. It is a homesickness without nostalgia, without the desire to return to the same, to be identical to oneself. The encounter with the other which produces a…

Purpose: To examine how cognitive speed of processing training affects driving mobility across a 3-year period among older drivers. Design and Methods: Older drivers with poor Useful Field of View (UFOV) test performance (indicating greater risk for subsequent at-fault crashes and mobility declines) were randomly assigned to either a speed of…

The number of automobile recalls in the U.S. has increased sharply in the last two decades, and the numbers of units involved are often counted in the millions. In 2010 alone, over 20 million vehicles were recalled in the United States, and the massive recalls of full model lines by Toyota have brought this issue to the front pages around the…

Theory and practice in education are interrelated and interdependent. The credibility of any set of postulates depends upon how well the position holds up in practice. There are three ways we can utilize theory in practice: (1) to reexamine our traditional approaches; (2) to give some direction to our future practices; and (3) to generate…

The article presents six remedial handwriting activities which address a variety of deficits commonly affecting the handwriting of learning disabled (LD) students. Each activity is presented with a rationale, step-by-step instructions, exemplary worksheets as necessary, and suggestions for teaching. In the "Coin Challenge" students learn correct…

The purpose of this study was to begin to explore the link of gesture and voice when teaching children and to examine how the children used these gestures in singing. Semi-structured interviewing techniques and observation were used extensively to collect information from the respondents. Five children were asked to participate in this preliminary…

Analysis of accident rates for 64 visually impaired persons licensed to drive with Bioptic Telescopic Spectacles determined that they were not more likely than controls to have a first accident, but those having one accident were more likely to have additional accidents. They were at fault in 82 percent of their accidents. (Author/VW)

This study investigated observational strategies that were used by six experienced physical education teachers when viewing a videotape of motor skills (standing vertical jump, overarm throw, tennis serve, basketball jump shot and dance sequence). Four observational frameworks were proposed as being representative of subdisciplinary knowledge…

The author offers curriculums, teaching guides, assessment instruments, and course descriptions for teaching independent living skills to handicapped adolescents and young adults. A guide on cooking and eating is designed to teach students how to use cooking utensils, cook healthy meals, plan nutritious meals, shop wisely, and budget food…

These classroom guides, designed to accompany the daily CNN (Cable News Network) Newsroom broadcasts for the month of May, provide program rundowns, suggestions for class activities and discussion, student handouts, and a list of related news terms. Topics include: Chelsea Clinton decides to attend Stanford University, Zaire's president and rebel…
