This paper presents the results of an extensive research study to develop a national model for an undergraduate curriculum in Industrial engineering. A departmental reform strategy was developed and applied to reengineer the IE curriculum. The reform strategy began with identifying the voice of the customer, including both industry and academic institutions which employ or enroll IE students after they graduate with their IE undergraduate degree. The emerging topics and desired characteristics of undergraduate IE graduates were identified in an earlier research study. These emerging topics were used in a focus group to identify high-level knowledge clusters of information that future IE graduates would need to master based on possible future work scenarios. The emerging topics were mapped to the high level knowledge clusters to generate curriculum requirements of future progress. This research effort developed a revised IE curriculum that can be used as a national model for IE departments. This curriculum focuses on nontraditional industry sectors, incorporating enhanced instructional strategies that can improve learning and retention, as well as state-of-the art technologies that support these strategies. The national model also includes material to help engineers gain knowledge that will help to prepare them for roles of leadership and management in their careers, as well as provides for recruiting strategies to increase the numbers of underrepresented minorities and women in IE programs. This paper describes the approach used in this research effort to develop the national model, as well as details of the resulting model for undergraduate IE curriculum. © American Society for engineering Education, 2007.

In multi-agent systems, blackboard communication provides an easy way for agents to communicate. However, in a distributed architecture, the blackboard is commonly implemented in a single node, that is the "blackboard server". This approach may work well for a small number of agents. Nevertheless, when the number of agents increases, the blackboard server becomes the bottleneck for the system scalability. In this work we propose a novel agent communication system based on distributed-shared mechanisms that allows the implementation of a shared address space on a distributed system, without centralizing the blackboard. Our idea is to distribute the shared data over the nodes and use a message passing sub-system, totally transparent to the agents. We implemented this idea in a multi-agent system based on social laws, and used a distributed-shared memory system to handle the messaging. We created a conflict simulator, and showed that the distributed-shared mechanisms easy the implementation of a truly distributed blackboard.

Echolocating bats have long demonstrated the potential for air-coupled sonar to guide agile navigation through complex 3D environments. While air-coupled sonar has been extensively used in mobile ground robotics and a considerable amount of the bat's auditory system has been studied, little work has been done to understand how the neural circuitry of the bat can integrate echoes into a coherent, behaving system. This paper addresses the unique characteristics of bat echolocation and how they impact the design of a neuromorphic VLSI-based echolocation system. By constructing a system to solve bat-specific sensorimotor tasks the authors have encountered a number of interesting issues and questions that commonly face neuromorphic VLSI designers. Successes, problematic issues, and future directions are discussed

Intrusion detection systems (IDSs) have been substantially improved in recent past. However, network attacks have become more sophisticated and increasingly complex: many of current attacks are coordinated and originated in multiple networks. To detect these attacks, IDSs need to obtain information on network events from multiple networks or administrative domains. This work demonstrates that a Distributed IDS (DIDS) can be composed of existing IDSs, improving the detection of misuses in a multiple network environment. We use a grid middleware for creating a service-based intrusion detection grid. We demonstrate through experimental results that the proposed DIDS allows the integration of heterogeneous existing IDSs and improves the detection of attacks by exploring the synergy between existing IDSs.

The Department of Technology systems (TSYS) at East Carolina University has implemented a new faculty mentoring process to enable junior faculty members to learn from senior faculty members as they prepare for a career in academia. Five tenured professors and associate professors in the TSYS department have recently established a new process to mentor faculty members within the department who have begun not yet completed their initial tenure process at a major university. This process includes a series of workshops regarding academic performance expectations during the early stages of an academic career. Our commitment to new faculty takes on several related, yet distinct features. Examples of these initiatives include: 1) reduced workloads for new faculty for the first two years to enable them to generate individual and collaborative research activities, funded grants, and publications, 2) periodic university-wide training to learn policies and procedures that affect day-to-day activities on a college campus, 3) periodic workshops hosted by senior faculty mentors, and 4) one-on-one discussions between senior faculty members and junior faculty members to encourage candid dialogue between professional colleagues. Another feature of the mentorship philosophy is a proposal to the dean of the college to offer newly hired faculty a contractual start date of July 1steach year instead of starting their contract one week prior to the start of fall classes, normally in late August. This additional period of time will be used to train new faculty in essential policies and procedures, to complete a variety of administrative tasks on campus, to get a head start on preparing for classes in the fall, and cleaning up those supplemental tasks that accompany every move to a new location. The goal of this early commitment to new faculty is to reduce the stress associated with preparing for a new course, in a new environment, with a new set of operating procedures. This will also enab

Statechart has been utilized as a visual formalism for the modeling of complex and interactive systems for its illuminating features on describing properties of causality, concurrency, and synchronization. This paper presents the application of satechart to the modeling, design and implementation of an elevator system, whose system behavior involves aggregating complexity of state descriptions, and imposition of underlying control policy. Based on the operational flow of an elevator, we derive the associated statechart model by looking into the inherent hierarchical structure of the elevator. The advantage of the proposed approach is the clear presentation of system behavior in terms of conditions and events that cause the transitions in system dynamics. Implementation of the controlled elevator based on the modeled statechart is also presented.

The Broadband Wireless Access (BWA) technology has been proposed to support different traffic classes with distinct quality of service (QoS) requirements in broadband metropolitan area networks. Therefore, as part of its specifications, such a system must properly address the combined requirements of wireless communications and multimedia applications. We propose in this paper an extension to the MAC protocol presented in [1, 2], by assigning variable priorities to the network stations sharing access to the communication channel. An analytical model to evaluate the performance of the proposed protocol is also developed and results obtained for the messages waiting times at different stations are presented. In addition, simulation data are used to compare the results obtained from the analytical model presented previously. It is concluded that the proposed variable priority MAC protocol is able to improve channel utilization and provide throughput and queueing delay fairness among the stations in the network. © 2006 SBrT.
