Integrated Copyright Protection in Peer-to-Peer Networks
Authors: Xiaosong Lou, Kai Hwang, Runfang Zhou
Venue: Proceedings of the 27th International Conference on Distributed Computing Systems Workshops (2007)

We propose an integrated copyright-protection scheme for large-scale content delivery over the Internet. We focus on using trust-enhanced peer-to-peer (P2P) networks. Our framework integrates anonymous peer authentication, content poisoning, peer collusion detection and reputation aggregation. Some of the trust and security mechanisms are newly developed and first-time reported. Complementary protection techniques from DRM (digital right management) and watermarking are explored for P2P copyright protection. The proposed integrated system enables large-scale distribution of copyrighted digital content in existing P2P networks such as Gnutella, KaZaA, BitTorrent, eMule, etc. Analytical and simulation results are reported to support the claimed advantages. The reported trust-enhancement mechanisms, gossip aggregation protocol, and experimental results have broader impact to future Internet applications. The copyright-protection system will widen the legal applications of P2P networks in business services, e-commerce, and distance learning, where intellectual property rights are of primary concerns.

Authors: Gavin LaRowe, Ryutaro Ichise, Katy Borner
Venue: Proceedings of the 11th International Conference Information Visualization (2007)

This paper reports a bibliometric analysis of evolving co-author networks. Using 5,009 articles covering the years 1993 to 2005 from Transactions D. (Information Systems) of the Institute of Electronics Information and Communication Engineers (IEICE), we attempt to compare the network characteristics for each year, the co-author network characteristics for the entire time span, and the four major components of the entire data set. Finally, we analyze each of these in contrast to extant co-authorship network data and find that the pattern of co-authorship within Information Systems does not change significantly over this time period.
WikiTUI: leaving digital traces in physical books
Authors: Chih-Sung Andy Wu, Susan J Robinson, Alexandra Mazalek
Venue: Proceedings of the international conference on Advances in computer entertainment technology (2007)

This article describes the design of WikiTUI, a tangible user interface system that allows readers to manipulate multimedia information tied to page-level locations in common books. This system will also facilitate the exchange of information with other readers using wiki technology. While other projects have coupled the dual worlds of atoms and bits, few have combined the idea of collaborative and distributed authoring with tangible interfaces. WikiTUI not only bridges the real and digital worlds, but facilitates multiple contributions to a reference base spanning across these worlds. The goal of our work is to apply the paradigm of coupling atoms and bits in order to extend the collaborative annotation and authoring possibilities of wiki media.
Integrated online courseware for computer science courses
Authors: Michael T. Helmick
Venue: Proceedings of the 12th annual SIGCSE conference on Innovation and technology in computer science education (2007)

Computer Science CourseWare (CSCW) is a Web-based integrated online courseware system for the management of computer science courses developed by the Miami University Department of Computer Science and Systems Analysis. The system is designed to support a unified student experience for content delivery and programming (and general) assignment management. CSCW promotes incremental development through rapid feedback for students with its integrated Java style checking (using PMD [2]) and automatic grading capabilities. CSCW integrates with existing version control infrastructure (using Subversion [4]) and authentication infrastructure (LDAP or custom plug-in) to minimize administration. Paperless handling of programming assignments is encouraged with the ability for precise feedback to be entered by instructors for student consumption. CSCW focuses on the needs of courses using computer programs as a primary assessment measure. CSCW is actively being used at Miami University.
Feature selection using genetics-based algorithm and its application to speaker identification
Authors: M. Demirekler
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 01 (1999)

This paper introduces the use of genetics-based algorithm in the reduction of 24 parameter set (i.e., the base set) to a 5, 6, 7, 8 or 10 parameter set, for each speaker in text-independent speaker identification. The feature selection is done by finding the best features that discriminates a person from his/her two closest neighbors. The experimental results show that there is approximately 5% increase in the recognition rate when the reduced set of parameters are used. Also the amount of calculation necessary for speaker recognition using the reduced set of features is much less than the amount of calculation required using the complete feature set in the testing phase. Hence it is mote desirable to use the subset of the complete feature set found using the genetic algorithm suggested.
Accessible interface for multimedia presentation in inclusive education
Authors: Lourdes Moreno, Paloma Martínez, Belén Ruíz, Ana Iglesias
Venue: ACM SIGCSE Bulletin (2007)

Among the technological solutions to achieve an inclusive education, the educative electronic accessible resources providing content adaptability is an alternative which reduces discrimination. It also favors the inclusion with right equalities which can be used by students regardless of their specific need and use contexts. Following this line of adaptability of contents on the web, a practical case [1] has been launched: an accessible interface of a multimedia resource with caption and audio description that offers the user the control over the decision of which sound and/or visual alternatives he wants to be introduced to. This resource has been designed with Universal Design criteria which are found in the Inclusive Design methodological framework.

Authors: Masahiro Shiomi, Takayuki Kanda, Hiroshi Ishiguro, Norihiro Hagita
Venue: IEEE Intelligent Systems (2007)

This article reports on a field trial with four interactive humanoid robots at a science museum where visitors are encouraged tostudy and develop an interest in science. Participating visitors wore RFID tags touring the museum's exhibits. The trial system usedinformation obtained from the RFID tags to direct the robots' autonomous interactions with the visitors. The interactions includedgestures and utterances resembling the free play of children. The robots also guided visitors around several exhibits and explained theexhibits on the basis of sensor information. Visitors gave the robots good evaluations during a two-month trial. Another experimentduring the field trial compared in detail effects of exhibit-guiding and free-play interaction under three operating conditions. Theresults revealed that the combination of free-play interaction and exhibit-guiding positively affected visitors' experiences at thescience museum. This article is part of a special issue on Interacting with Autonomy.
Using evolution patterns to find duplicated bugs
Authors: E. James Whitehead,  Jr.
Venue:  (2006)

The widespread use of software configuration management repositories to record the evolution of a software project raises the possibility of mining these repositories to better understand how developers fix software defects. In the repository that records a software project's change history, there are many changes where developers fix bugs (known as bug fix changes) as opposed to adding new features or refactoring source code. Bug fixes are interesting, since they not only provide the source code of a bug, but also the source code for how the bug is fixed. This dissertation defines 27 static bug fix patterns, which are automatically extractable, based on the syntax components and context of the source code involved in bug fix changes. Instances of static bug fix patterns are extracted from the configuration management repositories of seven open source projects, all written in Java (ArgoUML, Columba, Eclipse, JEdit, Scarab, Lucene, and MegaMek). Defined static bug fix patterns cover 45.7% to 63.6% of the total bug fix changes in these projects. Two classes of static bug fix pattern instances, those related to if statements and method calls, together account for 44.6% to 60.3% of all observed static bug fix patterns. Several analyses were performed on the extracted pattern instances on the projects. This dissertation also presents a bug finding algorithm, BugMem, to find duplicated bugs using bug fix memories: a project-specific bug and fix knowledge base developed by analyzing the history of bug fixes. This approach is a learning process, hence identified bug patterns are project-specific, the number of bug patterns grows as the software evolves, and high-level project-specific bugs can be detected. The algorithm and tool were assessed by evaluating if duplicated bugs and fixes in project histories could be found in the bug fix memories. Analysis of five open source projects (ArgoUML, Columba, Eclipse, JEdit, and Scarab) shows that, for these projects, 17.5%--32.4% of bugs appear repeatedly in the memories, and 7.5%--13.0% of bug and fix pairs are found in memories. The results demonstrate that project-specific bug fix patterns occur frequently enough to be useful as a bug detection technique. Furthermore, for the bug and fix pairs, it is possible to both detect the bug and provide a strong suggestion for the fix.
Modelling Nonrigid Object from Video Sequence Based on Power Factorization
Authors: Guanghui Wang, Guoqiang Sun, Xingtang Li, Shewei Wang
Venue: Proceedings of the 16th International Conference on Artificial Reality and Telexistence--Workshops (2006)

Recovering the 3D structure and motion of nonrigid object from a monocular image sequence is an important and difficult task in computer vision. Many previous methods on this problem utilize the extension technique of SVD factorization based on rank constraint to the tracking matrix. In this paper, we propose a constrained power factorization (CPF) algorithm that combines the orthonormal constraint and the replicated block structure of the motion matrix directly into the iterations. The proposed algorithm overcomes the limitations of previous SVD based methods. It is easy to implement and can even cope with the tracking matrix with missing data. Based on the solutions of the CPF, a novel sequential factorization technique is proposed to recover the shape and motion of new frames in realtime. Extensive experiments on synthetic data and real sequences validate the effectiveness of the algorithm and show noticeable improvements over the previous methods.
Dynamic simulation of chemical process as a tool to teach "the real problem" of identification and control
Authors: M. S. Basualdo
Venue: Proceedings of the Frontiers in Education Conference, on 1995. Proceedings., 1995 - Volume 02 (1995)

Simulation is the construction and use of a computer based representation, or model, of some part of the real world as a substitute vehicle for experiment and behavior prediction. In an environment of change, as the control of a chemical process, it offers an attractive opportunity for future engineers to try out the real control problem. The paper examines the practical use of simulation, within process control application areas, and the benefits released by the undergraduate pupils. The discussion draws on a study of the employment of simulation, which serves as an authentic pilot plant, to design an adequate feedback SISO control structure of a distillation column. Concluding the paper, several proofs are carried out in order to identify the nonlinear system and then the controlled plant is tested for reference and load changes.

Becoming the total quality manager (TQM) [engineering education]
Authors: J. B. Re Veele
Venue: Proceedings of the 28th Annual Frontiers in Education - Volume 03 (1998)

Because so few universities and colleges understand, teach and/or practice the philosophy, concepts and tools of total quality management (TQM), industry practitioners have for many years been providing this much-needed education and training in a variety of venues, both to recent graduates and their more senior colleagues. This paper reviews the intent, content and results of a comprehensive TQM course which has been taught under the sponsorship of the Institute of Industrial Engineers (IIE) and The George Washington University Continuing Engineering Education Program (GWU/CEEP).

Estimation of the velocity of mobile units in microcellular systems using the instantaneous frequency of the received signals
Authors: G. Azemi
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 200. on IEEE International Conference - Volume 02 (2001)

Handover processes in microcellular systems are more involved than in cellular systems. In particular, microcellular systems suffer from the so-called corner effect where line-of-sight between the mobile station and the base station is suddenly lost when the mobile rounds a comer. As a result, the received signal drops rapidly below threshold level and the call can be lost. It has been shown that, if an accurate estimation of the velocity of the mobile unit is available, the call can be rescued by applying short temporal window averaging on the received signal. Current methods for estimating the velocity of mobile units in microcellular systems are based on the level crossing rate of the envelope of the received signals. This paper presents a new velocity estimator based on the instantaneous frequency of the received signal. The performance of the proposed estimator is shown to be superior to that of the level crossing rate method. The average relative error of the proposed estimator is down to below 8% whereas that of the LCR method reaches 14%.
Initial evaluation of hidden dynamic models on conversational speech
Authors: J. Picone
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 01 (1999)

Conversational speech recognition is a challenging problem primarily because speakers rarely fully articulate sounds. A successful speech recognition approach must infer intended spectral targets from the speech data, or develop a method of dealing with large variances in the data. Hidden dynamic models (HDMs) attempt to automatically learn such targets in a hidden feature space using models that integrate linguistic information with constrained temporal trajectory models. HDMs are a radical departure from conventional hidden Markov models (HMMs), which simply account for variation in the observed data. We present an initial evaluation of such models on a conversational speech recognition task involving a subset of the SWITCHBOARD corpus. We show that in an N-best rescoring paradigm, HDMs are capable of delivering performance competitive with HMMs.

Authors: M. Chrzanowska-Jeske, G. Greenwood, B. Wang
Venue: Proceedings of the Evolutionary Computation on 2002. CEC '02. Proceedings of the 2002 Congress - Volume 02 (2002)

We introduce a new procedure for constructing nonslicing floorplans with soft modules. The procedure uses an evolution strategy to place hard modules, after which the final best placement is relaxed. The procedure is computationally efficient and our results surpass recently published results using the MCNC benchmarks.
A longitudinal study of undergraduate women in engineering and science
Authors: S. G. Brainard
Venue: Proceedings of the Frontiers in Education Conference,1997. on 27th Annual Conference. Teaching and Learning in an Era of Change. - Volume 01 (1997)

With a six-year grant from the Alfred P. Sloan Foundation, the Women in Engineering (WIE) Initiative at the University of Washington, USA, is conducting a longitudinal study of undergraduate women pursuing degrees in science or engineering. Now in its sixth year, five of six cohorts of approximately 100 students each year have been added to the study. The objectives of this study are to: (a) determine a more accurate measure of retention by tracking individual students through their science and engineering academic career; (b) examine the factors affecting retention of females in science and engineering; (c) increase the retention rates of female students pursuing degrees in science and engineering by providing interventions for the students themselves, primarily during the freshman and sophomore years which are critical attrition points; and (d) report these factors to the dean and departments involved for consideration in policy development.
Bioinformatics: a new field in engineering education
Authors: R. Hughey
Venue: Proceedings of the Frontiers in Education Conference, 2001. 31st Annual - Volume 02 (2001)

Bioinformatics is a new engineering field poorly served by traditional engineering curricula. Bioinformatics can be defined in several ways, but the emphasis is always on the use of computer and statistical methods to understand biological data, such as the voluminous data produced by high-throughput biological experimentation including gene sequencing and gene chips. As the demand has outpaced the supply of bioinformaticians, the UCSC School of Engineering is establishing undergraduate and graduate degrees in bioinformatics. Although many schools have or are proposing graduate programs in bioinformatics, few are creating undergraduate programs. In this paper we explore the blend of mathematics, engineering, science, and bioinformatics topics and courses needed for an undergraduate degree in this new field.
The Case for Distributed Execution Replay Using a Virtual Machine
Authors: Nicolas Loriant, Jean-Marc Menaud
Venue: Proceedings of the 15th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2006)

Debugging grid systems is complex, mainly because of the probe effect and non reproducible execution. The probe effect arises when an attempt to monitor a system changes the behavior of that system. Moreover, two executions of a distributed system with identical inputs may behave differently due to non determinism. Execution replay is a technique developed to facilitate the debugging of distributed systems: a debugger first monitors the execution of a distributed system and then replays it identically. Existing approaches to execution replay only partially address the probe effect and irreproducibility problem. In this paper, we argue for execution replay of distributed systems using a virtual machine approach. The VM approach addresses the irreproducibility problem, it does not completely avoid the probe effect. Nevertheless, we believe that the full control of the virtual hardware addresses the probe issue well enough to debug distributed system errors.
The Infinity Project: building a high school curriculum which emphasizes the engineering, math, and science principles of modern technology
Authors: M. A. Yoder
Venue: Proceedings of the 30th Annual Frontiers in Education - Volume 01 (2000)

A bold new plan has been initiated to bring state-of-the-art science-based technology and engineering education to high schools. This effort, called The INFINITY Project, aims to develop a novel and interactive curriculum emphasizing the engineering fundamentals and the fun of the modern high-tech age. This course isn't about "surfing the web"-rather, it teaches students about the science and engineering which enable the web. This course doesn't focus on how to use email to reach friends and family-rather, it teaches the physics and modern engineering which have given rise to cellphones and high speed digital networks. This course does not focus on how to use computers to play video games or DVD players to watch high resolution digital videos-rather, it focuses on the basic mathematics, and algorithms which enable these devices to entertain us and enrich our lives.
On Sorting Multiple Bitonic Sequences
Authors: De-Lei Lee, Kenneth E. Batcher
Venue: Proceedings of the 1994 International Conference on Parallel Processing - Volume 01 (1994)

Bitonic sorters sort a single bitonic sequence into an ascending sequence. A multi-bitonic sorter is presented here, which sorts k bitonic sequences of n keys each into an ascending sequence in at most \left( {\left\lceil {\log _2 \left( {k + \left\lceil {\frac{k} {2}} \right\rceil } \right)} \right\rceil+ 1} \right)\left( {\left\lceil {\log _2 n} \right\rceil- 1} \right)+T(1,k)+\left\lceil {\log _2 k} \right\rceil +1 time delay, where T(1,k) is the time delay needed to sort k keys in order; and k is any integer not restricted to 1.
The 8/sup th/ international conference on communications systems: system level buffer size estimation on QoS demands
Authors: V. G. Luo, J. Z. Gu
Venue: Proceedings of the The 8th International Conference on Communication Systems - Volume 02 (2002)

Buffer size estimation on QoS demands of a multimedia communication system is an important and challenging issue. Because the QoS is often related with many aspects, it is hard to resolve this problem with an analytic method based on a mathematical model. We propose a simulation method based on an operational Distributed Co-Design Model (DCDM). This method is used in the ROCS, and the operating process is shown by taking the MPEG video transmission over a wireless channel.
R-Sentry: Providing Continuous Sensor Services against Random Node Failures
Authors: Shengchao Yu, Yanyong Zhang
Venue: Proceedings of the 37th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (2007)

The success of sensor-driven applications is reliant on whether a steady stream of data can be provided by the underlying system. This need, however, poses great challenges to sensor systems, mainly because the sensor nodes from which these systems are built have extremely short lifetimes. In order to extend the lifetime of the networked system beyond the lifetime of an individual sensor node, a common practice is to deploy a large array of sensor nodes and, at any time, have only a minimal set of nodes active performing duties while others stay in sleep mode to conserve energy. With this rationale, random node failures, either from active nodes or from redundant nodes, can seriously disrupt system operations. To address this need, we propose R-Sentry, which attempts to bound the service loss duration due to node failures, by coordinating the schedules among redundant nodes. Our simulation results show that compared to PEAS, a popular node scheduling algorithm, R-Sentry can provide a continuous 95% coverage through bounded recoveries from frequent node failures, while prolonging the lifetime of a sensor network by roughly 30%.
