All segments of the wireless industry - cellular, personal communication services (PCS), paging, and specialized mobile radio (SMR) - are expected to grow at double-digit rates. In 1993, wireless services accounted for only $40 billion or 9% of the $640 billion telecommunications market, but by the year 2000, wireless is expected to control $200 billion or 18%, of an expected $1.1 trillion telecommunications market [1]. This phenomenal growth in wireless communications has put new demands on engineering technology curricula. Industry seeks graduates with appropriate background and training in wireless technologies. Electronics engineering technology (EET) graduates are not only expected to understand the theory of state-of-the-art wireless technologies, but also to exhibit hands-on analytical and problem solving skills. To address these changing industrial needs, it is imperative that new courses in wireless technologies be developed and incorporated into the Electronics Engineering Technology program. To help achieve this goal, a survey was conducted in the wireless industry to determine the required level of training for EET graduates. This paper describes a proposed wireless technology lecture/laboratory course implementing the future trends identified through feedback from the wireless industry.

The industrial workplace models of team-dynamics tend to misrepresent the character of collaborative activities and professional relationships in educational communities. An alternative model is suggested of self-directed, of educators in an creating academic work units with all the characteristics of positive team formations in business and industry, and the additional qualities of reciprocity and kindness found in friendship circles. A campus in a system of for-profit post-secondary DeVry Institutes is employed as an example of the benefits of organizing physical of educational activities in an integrated manner. Educators, support staff and technical resources are brought together across the range of the institution's educational offerings, creating by the campus as open space the conditions for successful informal teams in institutions of higher learning.

Madness is perpetually bound up with contemporary works of art. Michel Foucault, toward the end of Madness and Civilization, describes contemporary texts as frequently “explod[ing] out of madness” (286), creating a dialectic in which madness and art continually, radically oppose one another. The relationship between unreason and art becomes one of competition, “a game of life and death” (287). An insurmountable gulf exists between the two because “madness is the absolute break with the work of art” (287), which tries to make sense of the world.

In this paper, we present a scheme where a (d - 1)-dimensional subcube is allocated in a faulty d-dimensional circuit-switched hypercube in the presence of up to 2(d - 1) faulty nodes. The scheme is then extended to allocate a (d - 1)-dimensional subcube in the presence of a combination of faulty nodes and faulty links. Theoretical proofs and simulation results are presented to analyze the performance of the scheme.

Summary form only given. According to a study by the College Board, today's average college student is a female in her thirties with children and a job. Such students frequently have difficulty attending a traditional full-time college program, but the alternatives may not meet their needs either. In an effort to combine the benefits of the classroom and lab experiences, the alternative scheduling of evening programs, and the relatively short time span of a full-time degree program, DeVry Institute of Technology has developed an Accelerated Computer Information Systems program. The Accelerated program allows students to attend class 12 hours a week (one evening and all day Saturday). This program enables students to earn a bachelor of science degree in Computer Information Systems in just three and one-third years (attending twenty consecutive 7-8 week sessions). In each session, students take two courses, with class sit time reduced by at least 30%. To enable students to achieve the course objectives, we have blended a distance learning component with a traditional classroom component. In addition to lectures and labs, instructors use Internet technologies such as web forums, Asynchronous Learning Networks, web pages, and e-mail to assist students in mastering the course objectives as outlined in our standard curriculum guides while minimizing the time they need to spend in a classroom.

The display of energy of ultrasonic backscattered echoes simultaneously on a joint time-frequency (t-f) plane reveals critical information pertaining to time of arrival and frequency of echoes. The quadratic t-f distributions play important role in displaying the energy of the signal on a joint t-f plane. The t-f energy distribution of the signal is dependent on a weighting function, kernel, of generalized quadratic t-f distribution. This kernel, a function of product of time lag and frequency lag variables, controls the t-f concentration of the signal and the suppression of artifacts generated by the quadratic t-f distribution. A generalized exponential product (GEP) kernel function is explored in this paper, Exponential (i.e., Choi-Williams) distribution is a special case of this generalized exponential distribution. A whole family of Quadratic exponential distributions can be generated by varying the parameters of the generalized exponential product kernel. We evaluate these parameters on the basis of optimum concentration of the ultrasonic backscattered echoes, resolution of defect echoes, suppression of the cross-terms artifacts, and performance in the presence of noise. These parameters are evaluated by reducing the cross-terms and keeping auto-terms on the ambiguity plane close to the ideal. It is shown that by controlling the parameters of the generalized exponential product kernel we can achieve better performance in the form of time-frequency concentration, and resolution for multiple echoes as compared to exponential distribution. The application of GEP kernel to ultrasonic experimental data, with properly chosen parameters, not only discern the defect echo embedded in grain echoes but diminish the cross-terms generated by the bilinear structure of the t-f distribution.
