Remote experimentation is the process of conducting real lab experiments without being physically in contact with lab devices. Recently, the development of Internet technologies fostered the spread of online laboratories, and significant benefits helped establish remote experimentation as a potential substitute to real experimentation. Internetworking lab experiments usually involve very expensive hardware;and providing remote access to this type of laboratories is highly desired, especially when a large number of students must share a limited set of devices. Very few remote internetworking laboratories have previously been implemented, and they had several drawbacks. In this paper, we discuss our design of a Remote Internetworking Laboratory which provided access to the internetworking lab at the American University of Beirut (AUB). The uniqueness of our approach is that it uses VLANs (Virtual LANs) to build network topologies, a technique that separates network subnets into different broadcast domains before allowing users to configure each lab device. The proposed scheme overcomes the limitations of other designs, and allows users to build any desired network topology and configure the lab devices in real-time. Many technical and educational features were integrated into the system, and possible enhancements were suggested based on several evaluation criteria. © American Society for engineering Education, 2006.

The neural networks are successfully applied to many applications in different domains. However, due to the results made by the neural networks are difficult to explain the decision process of neural networks is supposed as a black box. The explanation of reasoning is important to some applications such like credit approval application and medical diagnosing software. Therefore, the rule extraction algorithm is becoming more and more important in explaining the extracted rules from the neural networks. In this paper, a decompositional algorithm is analyzed and designed to extract rules from neural networks. The algorithm is simple but efficient;can reduce the extracted rules but improve the efficiency of the algorithm at the same time. Moreover, the algorithm is compared to the other two algorithms, M-of-N and Garcez, by solving the MONK's problem. © Springer-Verlag Berlin Heidelberg 2006.

Vertically aligned carbon nanotube field emission devices fabricated by furnace thermal chemical vapor deposition at atmospheric pressure

Journal of Vacuum science and Technology B: Microelectronics and Nanometer Structures 2006年第3期24卷 1190-1196页

Multiwalled carbon nanotubes (CNTs) grown by thermal chemical vapor deposition (CVD) in a tube furnace at atmospheric pressure are reported. The CNTs were synthesized at 750 °C using C2 H2 as the carbon source and a mixture of Ar H2 (80 vol %:20 vol %) as a carrier gas, with N H3 serving as a processing reagent. The catalytic properties of nickel (Ni) particles are strongly affected by the CVD process parameters and this effect is reflected in the morphologies and field emission behaviors of the as-grown CNTs. The flow rate ratio of N H3 to C2 H2 is found to be critical to the formation of vertically aligned CNTs, which demonstrated better field emission characteristics than the randomly oriented nanotubes. The successful synthesis of vertically aligned CNTs at atmospheric pressure in a tube furnace is beneficial for large area mass production such as flat panel field emission displays at lower cost. © 2006 American Vacuum Society.

This paper describes the development of a Multi-Electrode Array (MEA) with Guided Network for Cell-to-Cell Communication Transduction using a standard integrated circuit (IC) fabrication process. Unlike conventional electronic system, bio-system requires a special handling environment that is uncommon in conventional IC technology. The work presented here demonstrated the interaction between electrically active cells such as neuron and cardiac cells and an IC based system. Through a carefully designed array, and ionic action of a cell, extracellular signals can be captured and imaged. © 2006 IEEE.

With support from HBCU-UP (Historically Black College and University - Undergraduate program) at National science Foundation (NSF), the ACTION (Advanced Curriculum and Technology-Based Instructional Opportunities Network) program at University of Maryland Eastern Shore (UMES) is promoting inquiry based active learning and research projects among undergraduate STEM (science, Technology, engineering and Mathematics) majors. This paper highlights efforts of selected freshman and sophomore engineering majors while performing ACTION projects at UMES. Integration of Lego-Mindstorm Robotic Invention System as well as ProEngineer and ProMechanica software for solid modeling and analysis are the focus of the reported endeavors. Involvement in ACTION projects have not only reinforced concepts introduced in classroom setting but have inspired students to be engaged in the process of learning and discovery well beyond expectations of the course syllabi, format, and structure. © American Society for engineering Education, 2006.

This presentation builds on panel discussions that began at the ASEE 2004 National Conference and continued at the 2005 Conference. Our focus is on promoting diversity in engineering education, with an emphasis on graduate education. This paper serves as a summary and introduction to this session, which is co-sponsored by three ASEE divisions-the Graduate Division, Women in engineering Division, and Minorities in engineering Division. In previous years, we presented evidence of the need for diversity in engineering education to promote the national good. We discussed specific issues of concern for promoting diversity in graduate engineering education. We outlined an overall strategy for achieving diversity in engineering education in general and in graduate engineering education in particular, based on a holistic model applicable to both education and industry. Now our goal is to identify best practices which can help to implement this strategy and to disseminate these practices to a broad audience. © American Society for engineering Education, 2006.

Neural prostheses have received considerable attention due to their potential to dramatically improve the quality of life of severely disabled patients. Cortically-controlled prostheses are able to translate neural activity from cerebral cortex into control signals for guiding computer cursors or prosthetic limbs. Non-invasive and invasive electrode techniques can be used to measure neural activity, with the latter promising considerably higher levels of performance and therefore functionality to patients. We review here some of our recent experimental and computational work aimed at establishing a principled design methodology to increase electrodebased cortical prosthesis performance to near theoretical limits. Studies discussed include translating unprecedentedly brief periods of “plan” activity into high information rate (6.5 bits/s) control signals, improving decode algorithms and optimizing visual target locations for further performance increases, and recording from chronically implanted arrays in freely behaving monkeys to characterize neuron stability. Taken together, these results should substantially increase the clinical viability of cortical prostheses.

OBF (Orthonormal Basis Function) Fuzzy models have shown to be a promising approach to the areas of nonlinear system identification and control since they exhibit several advantages over those dynamic model topologies usually adopted in the literature. Although encouraging application results have been obtained, no automatic procedure had yet been developed to optimize the design parameters of these models. This paper elaborates on the use of a genetic algorithm (GA) especially designed for this task, in which a fitness function based on the Akaike information criterion plays a key role by considering both model accuracy and parsimony aspects. The use of linear (actually affine) and nonlinear local models is also investigated. The proposed methodology is evaluated in the modeling of a real nonlinear magnetic levitation system.
