This paper describes the curriculum details of an on-going NSF DUE project that commenced in the fall 2004 semester at the University of Oklahoma (OU). This three-year project offers a new active-learning and hands-on laboratory program that is interdisciplinary, in which engineering, geoscience, and meteorology students are encouraged to actively participate. The program is intended to generate a unique, interdisciplinary research-oriented learning environment that will train future engineers and meteorologists in the full set of competencies needed to take raw radar data and transform it into meaningful interpretations of weather phenomena. The heart of the program is the development of a set undergraduate courses, offered by the School of Meteorology and the School of electrical & computerengineering, that will provide hands-on laboratory experiences in the special knowledge and skills necessary for organizing real-time weather data, improving and preparing that data for display, and interpreting its meteorological and scientific significance. In addition, programs for middle school students have been generated for the purpose of increasing their interest in science and engineering prior to entering college.

The School of engineering at the University of Puerto Rico-Mayaguez (UPRM), has developed a module to integrate ethics into capstone design courses in the electrical and computerengineering (ECE) Department. This module entitled, "Social and Ethical Implications of engineering Design", helps students to reflect on issues and challenges associated with technological education that include (i) professional integrity, (ii) engineering, industry and social responsibility, and (iii) technological impact, societal and global awareness. This paper will describe this module and show how it has been implemented in ECE design courses in digital signal processing, power systems, applied electromagnetics, and electrical systems design. It also discusses student response by reporting student-based assessment results

This paper proposes a supervised version of a learning algorithm for a constructive neuro-immune network. The proposed methodology is developed by taking ideas from the immune system and learning vector quantization. The resulting classification algorithm is characterized by high-performance, similar to the ones produced by alternative methods in the literature, and parsimonious solutions, with a much smaller set of prototypes per class when compared with the other approaches. The number of prototypes is automatically defined by the convergence criterion. The algorithm requires a single user-defined parameter for training, associated with the convergence criterion, and the computational cost is sufficiently reduced to support applications involving large data sets.

This paper deals with joint channel estimation and pseudo-noise code acquisition for ultra-wideband communications. The estimation and acquisition in a realistic frequency selective channel, and in the presence of additive white Gaussian noise are based on the maximum-likelihood criterion. In particular, three systems are considered, namely, time-hopping, direct-sequence, and bi-orthogonal time-hopping CDMA digital systems. The efficiency of the synchronization process and the quality of the channel estimates are assessed and compared via analysis and simulations. Specifically, the performance of different systems are compared in terms of probability of correct synchronization, mean-square error of the channel estimates, and bit-error-rate.
