A nonlinear filter known as fuzzy cluster filter (FCF) is introduced. this filter can be used for different signal and image processing applications. the formulation of this filter is based on applying fuzzy clustering to a subset of the signal (or image) and finding the best candidate (i.e., the cluster prototype) for the output. the local statistics of the signal are used for learning the membership functions. Also, the performance of the filter is found for different signal to noise ratios (SNR) by using Monte Carlo simulations.

A system of T resources (wireless channels) shared by a number of un-buffered applications is considered. the shared transmission resources are defined to be the slots (packet transmission times) of a TDMA frame (service cycle). Packets which are not allocated a channel within the current service cycle are dropped. the quality of service (QoS) vector is equivalently described in terms of (diverse) packet dropping probabilities (p/sub i/), or (diverse) packet dropping rates (d/sub i/). From a precisely defined region of achievable QoS vectors, easy to implement scheduling policies that deliver the achievable QoS vectors are derived. As an example, a policy that delivers a target QoS vector is derived; its performance is verified through simulations.

the generic open architecture (GOA) framework is a Society of Automotive (SAE) Avionics systems Division standard, SAE AS4893. the GOA framework was developed as a framework for discussing open systems architecture and for identifying critical components and interfaces. the GOA framework is being used as a framework within the avionics community for developing a preferred set of interface standards catalog. this paper provides an overview of the GOA framework and other activities on-going within the SAE AS5C GOA subcommittee.

Traditions have us tied to a curriculum delivery format that is no longer viable and is detrimental to the student learning process. For well over a 100 years, undergraduate engineering programs have been structured within the format of academic-year semesters or quarters, and within these, to lumps of learning packages of 3- to 5-credit-hour courses. Such a traditional system developed naturally in that it accommodated the structure of institutional teaching. However, we no longer need be restrained by these traditions. the application of IT permits us to deliver subject material in smaller lumps that accommodate the learner as opposed to the teacher. By using computer-based learning and accommodating such technologies as the CD-ROM and Internet, certain types of courses are best delivered in modules. A typical 3-credit-hour course is best delivered by this technology in smaller lumps of 15 to 20 modules. Each engineering discipline might distribute these learning modules in a course over that program's 4- to 5-year degree where best suited for the students (e.g. chemical engineers need a different delivery pattern than electrical engineering in thermodynamics). Also, a core course in the basics of electronics and electrical systems is needed in an entirely different sequence by those majoring in electrical engineeringthan by those majoring in industrial engineering. By reducing the lumpiness of the subject material from 3 to 5 credit-hours to smaller modules for each course, subject material can be delivered "just in time". Another advantage is that students experience improved learning using IT.
