The so-called "last mile" of the telecommunications network, which links residences and business locations to the network, has traditionally been the last bastion of old technology. Residential voice service is still mostly provided via an analog signal over a pair of copper wires that connects the telephone to a switching system in a central office. The high-speed digital technology employed by modern switching systems and inter-office transmission systems does not extend to most residences. The local access network is a landscape of copper wires bound into large cables, splices, cross-boxes and other equipment that has provided voice-grade service over the years. However, the landscape is changing dramatically as both residential and business customers demand more and more bandwidth for a growing number of services including highspeed Internet access and video as well as voice. Teleos such as AT&T and Verizon as well as Multi-Service Operators (MSOs) are both vying to provide the "triple play" (voice, data and video) to these customers. In order to provide the triple play, service providers are introducing digital transmission and optical fiber, which have revolutionized long-haul communication, to the local access network. The Telecommunication engineering technology program at RIT is responding to this trend by providing courses and laboratory facilities to introduce students to the associated technology. Our Telecommunication Systems Laboratory now features both passive optical network (PON) and hybrid fiber/coax (HFC) technology. These are two leading approaches to provide broadband access to support the triple play. In addition, we are developing new courses to cover topics such as video transmission and broadband network engineering. This paper presents the current status of our laboratory and course development along with our plans for future enhancements. © American Society for engineering Education, 2008.

The initial years of a tenure track position are difficult for a variety of reasons, including the lack of preparation and experience that new faculty members have for various aspects of the job. Much advice has been given regarding the use of mentoring and workshops to accelerate the acclimatization period, but these methods may not involve the relaxed atmosphere and open discussion conducive to the development and free exchange of ideas and ideologies. In this paper, we discuss our approach of regular peer meetings of such discussions. Peer meetings promote the discussion of problems encountered by new faculty as the problems develop. Not only does discussing problems in such meetings assist in the creation of solutions, but everyone who participates in the discussion is thereafter prepared to avoid similar problems in the future. Considerations of group composition, group size, and what topics to discuss are examined. © American Society for engineering Education, 2008.

This paper presents the result of our experiment in a sophomore Circuit Analysis course using the learning-through-teaching method. The main goals of students teaching students are to have the student learn the material effectively and to promote life-long learning by cultivating self-learning. Details of how to make it a successful learning and teaching experience for the students are discussed. Topics discussed include: Why is self leaning important? How is a student teaching assignment organized? How are students motivated? How is the effectiveness of learning-through-teaching assessed? What are the common mistakes? Hopefully, the experience from the learning-through-teaching presented in this paper can provide useful information for others who are interested in this kind of cooperative learning practice. © American Society for engineering Education, 2008.

Teaching engineering and technology subjects involves conveying understanding of abstract information structures and processes such as complex telecommunications protocols, complex mathematical concepts, and data structures. These are multidimensional and can be difficult to grasp quickly. Supported by a Hewlett-Packard (HP) technology for Teaching grant, the School of engineering and technology at National University has embarked on a project to enable students to grasp these complex concepts more quickly and easily, using continuous dialog among students and instructors as the structures are first introduced and then examined from multiple perspectives through real-time interaction among students, small groups, and instructors. HP Wireless Tablet PCs are used to discuss and experiment with diagrams and processes in realtime. This allows combining lectures and problem-solving sessions into a single class session. Our hypothesis is that: 1) an in-depth learning of theory is accomplished, and 2) student engagement is enhanced. Presentation of theory by the instructor is integrated with application while the theory is still in the student's short-term memory. Students no longer have to wait for a separate session such as a recitation session to apply the concepts. This approach often takes less time. In addition to accelerating the learning process, expert instructors find this approach more rewarding as students grasp new concepts more quickly. Analysis of data captured from both students and instructors are presented to support our hypotheses, and our results are compared with similar research carried out by other universities. In addition, the level of interaction enabled by the use of HP Tablets in on-line classes is discussed. The best teaching tools available in existing on-line teaching platforms are compared with the additional tools available in on-site courses when every student has a wireless Tablet PC and specific recommendations are made to on-line teachi

Solution techniques for Markov decision problems rely on exact knowledge of the transition rates, which may be difficult or impossible to obtain. In this paper, we consider Markov decision problems with uncertain transition rates represented as compact sets. We first consider the problem of sensitivity analysis where the aim is to quantify the range of uncertainty of the average per-unit-time reward given the range of uncertainty of the transition rates. We then develop solution techniques for the problem of obtaining the max-min optimal policy, which maximizes the worst-case average per-unit-time reward. In each of these problems, we distinguish between systems that can have their transition rates chosen independently and those where the transition rates depend on each other. Our solution techniques are applicable to Markov decision processes with fixed but unknown transition rates and to those with time-varying transition rates.

This paper describes the objectives, strategies, assessment and evaluation, and special program features of the Rochester Institute of technology's (RIT) Multi-department engineering and engineering technology (MEET) Scholars program. This program began in December, 2004 and is designed to recruit, retain and graduate additional transfer students in our selected engineering and engineering technology degree programs. The MEET Scholars program represents a collaborative effort of five academic departments across two colleges, and the Enrollment Management and Career Services Division at RIT. All of the programs in the five participating departments are ABET-accredited, and require students to obtain one year of industry co-op experience before graduation. The MEET Scholars program builds upon our excellent infrastructure for mentoring students, and involves our mandatory cooperative education program - both of which help students address their financial needs and facilitate placement in the high technology workforce. RIT has an exceptional record in engineering student placement in industry after graduation and an excellent record for both retaining and graduating upper-division transfer students.

This article adds to the research literature on international R&D alliances by focusing on alliances formed by multinational corporations with Chinese organizations. Using publicly available information, we developed a sample of 80 international R&D alliances between multinational corporations and Chinese organizations in the information technology industry in China formed during the period from 1997 to 2003. We use these data to test hypotheses on the connections between the declared motives, organizational form and R&D activity function of such alliances. Our analysis shows that the two most frequent motives of multinational corporations when establishing R&D alliances with Chinese organizations are establishing vertical linkages and obtaining human resources. Within the context of a strong preference for non-equity-based cooperative agreements, our analysis also provides some evidence for an association between the choice of form and motive, strong evidence for an association between function and motive, and strong evidence for an association between the form and function. © 2005 Elsevier Inc.

Due to the scarce resources of small devices in wireless networks, it is preferable that security protocols be lightweight and energy efficient while being secure. In this paper, we describe the existing WLAN standard for authentication and key management (AKM), namely, IEEE 802.11i. The AKM protocol in 802.11i can be fairly energy hungry especially when mobile stations roam or temporarily disconnect from the infrastructure. We demonstrate the possibility of maintaining and allowing secure roaming and reconnections in WLANs while reducing the energy consumption of devices by proposing two modifications to the 802.11i protocol that are lightweight and energy-efficient. We provide performance comparison between our proposed schemes and the standard schemes. © 2005 IEEE.

The globalization of our economy has stimulated international collaborations on collegiate education. As a predominant manufacturing base and an emerging mass market, China has become an important base for engineering and technology (E&T) in the past decade. It is apparent that collaboration with Chinese universities on E&T education will help further our understandings of the needs and the developing trends for engineering and technology professionals. This article explores the potentials and issues of collaborating with Chinese universities for E&T education from a curriculum perspective. By analyzing the TAC of ABET accredited ECET curriculum at Western Carolina University and that from a representative Chinese university, East China University of Science and technology, the authors found that there are great potentials to collaborate with Chinese universities in E&T education. Though issues exist during the process of establishing such collaborations, they can be resolved through a thorough understanding of Chinese engineering curricula and careful planning.
