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.

2008 ASEE Annual Conference and Exposition

作者： Zhan, Wei Beasley, Ryan Goulart, Ana Elisa Texas A and M University Department of Electronics Engineering Technology Texas Aand M University Department of Electrical Engineering Technology Texas A and M University Telecommunications Engineering Technology Program Department of Engineering Technology and Industrial Distribution Texas A and M

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.

This paper discusses phase noise characteristics of an Fr oscillator focusing on a signal output position. Oscillation circuits can be divided into an amplifier and a feedback circuit. We compared that phase noise characteristics before passing through a feedback circuit or a after. As a result, it turned out that the slope of the phase noise characteristic does not relate to the signal output position. © 2008 The Institute of Electrical Engineers of Japan.

作者： C. Charoenlarpnopparut Pramote Jangisarakul Electronics and Communication Engineering Program Sirindhorn International Institute of Technology Thammasat University Thailand

A representation of an m-D convolutional encoder is analogous to the representation of a transfer function for a MIMO m-D FIR system. The encoder matrix is usually not square and thus finding its inverse typically employs the Moore-Penrose generalized inverse. However, the result may not be FIR (polynomial matrix) even if the generator matrix is a polynomial. In this paper a constructive algorithm based on the usage of Grobner basis is presented along with detailed examples. The result obtained can be parameterized to cover the class of all possible FIR inverses. In addition, by using the computation method of syzygy with the Grobner basis module, the syndrome matrix for a given m-D convolutional encoder is shown.

In this paper, the application of spectral factorization by using Grobner basis approach to the problem of 2-D finite support QMF filter bank design is proposed along with illustrative example. Earlier, it has been shown that the Grobner basis can be applied to solve the problem of 2-D factorization and its effectiveness in dealing with polynomial equation system are demonstrated. Despite the fact that there exist many good techniques for designing one dimensional QMF synthesis and analysis filter banks, the two-dimensional counterpart has a major bottleneck due to the generalization of 2-D spectral factorization. The proposed algorithm is the direct generalization of the 1-D QMF filter bank design by spectral factorization. Furthermore, the filter coefficients can be computed in symbolic forms and thus provide a good opportunity for further optimization if additional criteria are given.

作者： Mohammad S. Sharawi Murad Shibli Mohammad I. Sharawi Computer Engineering Department Philadelphia University Amman Jordan Mechanical Engineering Department and Mechatronics Graduate Program American University Sharjah UAE Electronics Engineering Department Princess Sumaya University for Technology Amman Jordan

This paper presents the design and mechatronics implementation of a human stress detection system (HSDS) using a biomechanics approach. A simple, compact and easy to use system is developed and built on a 2-layer PCB. It consists of two transducers, an LCD display and a micro-controller chip along with their respective interfacing circuits. After characterizing the two transducers, an algorithm was developed based on the measurements to classify the human stress condition. A simple classification rule that was adopted revealed that the system can detect 78% of the stressed examinees. The overall system success rate in identifying one of three states (relaxed, half stressed and stressed) was 60%. One major application for HSDS could be in the automotive industry were the driver condition is constantly monitored, and if a stress state is detected, the driver can be notified to stop the car and relax.

An RFID system consists of an RFID reader, a server connected to a database, and RFID tags attached to the objects needed to be identified. We are interested in the case where two tags are needed to be simultaneously scanned in a readerpsilas field, for which many protocols have been proposed in literature. They however are all insecure for the special case, where an adversary, acting as a reader, can penetrate the server and access data stored in the server. In this paper, we propose a protocol to remedy this problem for two-tag environment. In addition, it can be extended to more-than-two-tag environment without much increasing total amount of time to scan all the tags.

A New Anti-Collision Based on A-Priori Information

A New Anti-Collision Based on A-Priori Information

5th International Conference on Electrical engineering/electronics, Computer, Telecommunications and Information technology (ECTI-CON 2008), vol.2

作者： Sarawut Makwimanloy Piya Kovintavewat Urachada Ketprom Charturong Tantibundhit Chaichana Mitrpant Electrical and Computer Engineering Department Thammasat University Thailand RFID Technology and Applications Research Unit Nakhon Pathom Rajabhat University Nakhon Pathom Thailand RFID Program National Electronics and Computer Technology Center Thailand

A collision occurs when more than two tags present in the reader's field of a radio frequency identification system. Anti-collision algorithms such as binary trees and dynamic framed slotted aloha (DFSA) have been employed to prevent such a collision. The identification number of tag consists of 64 bits and certain parts of 64 bits can be considered a priori-information. This paper proposes a new anti-collision algorithm based on a-priori information about the manufacturer code. This prior-information reduces the number of bits to analyze in the algorithm, hence reduces the operation time for the faster read-performance. Results indicate that the proposed anti-collision algorithm required a less number of used time slots, thus minimizing the operation time more than 50% comparing to the existing ones.
