A quick development and delivery environment for test and exercises
Authors: D. Del Corso
Venue: Proceedings of the 30th Annual Frontiers in Education - Volume 02 (2000)

The paper presents a tool (X-LAMP) for quick design, development, and delivery of tests and interactive exercises for self-evaluation. The package allows the user to build groups of tests of various types, either as standalone modules or linked to theory pages. The tests can be delivered through the Internet or on CD-ROMs for independent use by students, or through controlled distribution with accesses monitored by the teacher.
Using the Internet for distance teaming/distance teaching
Authors: D. M. Etter, G. Orsak
Venue: Proceedings of the Frontiers in Education Conference on 1995. Proceedings., 1995 vol 1. - Volume 01 (1995)

This paper presents the results of two semesters of experiments involving distance teaming and distance teaching. In the Fall of 1994, students from senior-level digital signal processing classes at the University of Colorado and at George Mason University participated in joint project teams to design solutions to digital signal processing problems involving real data. In the Spring of 1995, a Special Topics in Digital Signal Processing course continued this joint experiment, with joint teaching by Professor Etter and Professor Orsak. Lectures were shared by video tape, and the Internet was used for general questions and comments between the students and the professors. Mosaic pages were developed relative to the classwork and were available on the World Wide Web. We believe that these experiences are excellent opportunities for students to prepare for the jobs, since companies frequently team their employees over widespread regions when undertaking large and detailed projects. At present, these industrial enterprises use leased analog and digital communication lines but they will no doubt switch to computer networks as the Information Superhighway becomes a reality. From a pedagogical point of view, this modern approach to teaming requires that educators develop in their graduates the skills required for this new reality. These skills include, among others, identifying expertise and interest within a larger distributed group, segmenting tasks in a meaningful fashion, integrating designs across a high-speed network verifying performance against specifications, and compiling and writing a comprehensive final report. The joint teaching efforts also allow universities to pool their talent, and hence, students have access to the wider pool of topics that are represented by a group of faculty at various universities who are interested in joint teaching.
Network-sensitive service discovery
Authors: An-Cheng Huang, Peter Steenkiste
Venue: Proceedings of the 4th conference on USENIX Symposium on Internet Technologies and Systems - Volume 4 (2003)

We consider the problem of network-sensitive service selection (NSSS): finding services that match a particular set of functional and network properties. Current solutions handle this problem using a two-step process. First, a user obtains a list of candidates through service discovery. Then, the user applies a network-sensitive server selection technique to find the best service. Such approaches are complex and expensive since each user has to solve the NSSS problem independently. In this paper, we present a simple alternative: network-sensitive service discovery (NSSD). By integrating network-sensitivity into the service discovery process, NSSD allows users who are looking for services to specify both the desired functional and network properties at the same time. Users benefit since they only have to solve a restricted version of the server selection problem. Moreover, NSSD can solve the NSSS problem more efficiently by amortizing the overhead over many users. We present the design of NSSD, a prototype implementation, and experimental results that illustrate how NSSD can be utilized for different applications.
Colombia Firm Energy Market
Authors: Peter Cramton, Steven Stoft
Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

A firm energy market for Colombia is presented. Firm energy-the ability to provide energy in a dry period-is the product needed for reliability in Colombia's hydro-dominated electricity market. The firm energy market coordinates investment in new resources to assure that sufficient firm energy is available in dry periods. Load procures in an annual auction enough firm energy to cover its needs. The firm energy product includes both a financial call option and the physical capability to supply firm energy. The call option protects load from high spot prices and improves the performance of the spot market during scarcity. The market provides strong performance incentives through the spot energy price. Market power is addressed directly: existing resources cannot impact the firm energy price.
Compaq's new engineering compute farm environment: moving forward with windows NT
Authors: Don Brace, Andrew Gordon, Scott Teel
Venue: Proceedings of the 1998 Conference on Large Installation System Administration of Windows NT (1998)

In the past, Compaq's design and verification distributed compute farm consisted of UNIX-based often times expensive proprietary hardware and operating systems. In addition, internal developers created site-specific load distribution software for the management of design verification compute intensive processing jobs. This environment offered Compaq design engineers (DEs) a finely tuned site-specific environment, where the benefits included on-site developers providing quick user-required modifications, in addition to a mature operating system environment. The downside included higher hardware purchasing and maintenance costs. However, with the emergence of Windows NT, Platform Computing's Load Sharing Facility (LSF) for Windows NT, the availability of Electronic Design Automation (EDA) applications for Windows NT, and high-end Intel-based workstations, a Compaq-based Windows NT LSF compute farm proved to be a viable solution. Compaq's internal systems engineers (SEs) and application engineers (AEs) began the process of developing a Windows NT-based compute farm environment that would provide a robust distributed compute farm to be used to facilitate the designing and verification of future Compaq products. This paper describes the issues encountered and the solutions required to bring the Compaq-based Windows NT LSF compute farm online and into production.
Context Awareness in Mobile Computing Environments
Authors: Christos B. Anagnostopoulos, Athanasios Tsounis, Stathes Hadjiefthymiades
Venue: Wireless Personal Communications: An International Journal (2007)

In this article, we report software architectures for context awareness in mobile computing environments, sensor centric systems and discuss context modeling issues. Defining an architecture for supporting context-aware applications for mobile devices explicitly implies a scalable description of how to represent contextual information and which are the abstraction models capable of handling such information. Using sensors to retrieve contextual information (e.g., user location) leads to a sensor network scheme that provides services to the applications level. Operations for capturing, collating, storing, and disseminating contextual information at the lowest level and aggregating it into increasingly more abstract models qualify the context-aware systems. In this article, we introduce context aware systems in mobile computing environments, review the basic mechanisms underlying the operation of such systems, and discuss notable work and important architectures in the area.
Towards expertise: the role of chunking in developing productive fluency in drawing (semester 1 summary)
Authors: Sona L. Hairabedian
Venue: Proceedings of the 6th ACM SIGCHI conference on Creativity cognition (2007)

"Chunking"--the process by which the mind absorbs information--has been a subject of study since the 1950s, when George A. Miller introduced the term. Research done since then by De Groot and Simon with master chess players and novices has shown evidence that experts chunk and retrieve learned information differently from novices. Other scholars, like D. N. Perkins, suggest that this difference may extend to other fields, like music and oral poetry. This paper explores the possible role of chunking in the process of gaining proficiency in drawing. It reports an observation study of a freshman drawing class through three months of learning, and shows 1.) How mental and physical skills were taught, according to the chunking principle, 2.) How evaluation skills were learned, and 3.) How a focus on complex skill learning sometimes drove a lower-level skill into unconscious competence--a step toward a state I call "productive fluency", which itself seems a step towards expertise.
Robust distant-talking speech recognition
Authors: J. Pearson
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1996. on Conference Proceedings., 1996 IEEE International Conference - Volume 01 (1996)

Most contemporary speech recognizers are designed to operate with close-talking speech and they work best in a quiet laboratory condition. There is an apparent need to render environment robustness to these systems. The objective of the paper is to explore utility of existing speech recognition technology in adverse "real-world" environments for distant-talking applications. A synergistic system consisting of microphone array and neural network (MANN) is utilized to mitigate environmental interference introduced by reverberation, ambient noise, and channel mismatch between training and testing conditions. The MANN system is evaluated with experiments on continuous distant-talking speech recognition. The results show that the MANN system elevates the word recognition accuracy to a level which is competitive with a retrained speech recognizer and that the neural network compensation performs better than some previously researched techniques.
Understanding Resiliency of Internet Topology against Prefix Hijack Attacks
Authors: Mohit Lad, Ricardo Oliveira, Beichuan Zhang, Lixia Zhang
Venue: Proceedings of the 37th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (2007)

A prefix hijack attack involves an attacker announcing victim networks' IP prefixes into the global routing system. As a result, data traffic from portions of the Internet can be diverted to attacker networks. Prefix hijack attacks are a serious security threat in the Internet and it is important to understand the factors that affect the resiliency of victim networks against these attacks. In this paper, we conducted a systematic study to gauge the effectiveness of prefix hijacks launched at different locations in the Internet topology. Our study shows that direct customers of multiple tier- 1 networks are the most resilient, even more than the tier- 1 networks themselves. Conversely, if these customer networks are used to launch prefix hijacks, they would also be the most effective launching pads for attacks. We verified our results through case studies using real prefix hijack incidents that had occurred in the Internet.
Managing a New Computer Device Development in a Creative ISO 9001 Certified Company: A Case Study
Authors: Wolfgang Molnar, Joe Nandhakumar
Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

This paper describes the findings of a case study that explores the micro level factors surrounding the processes of creativity and process management in a creative organization. The paper adopts an interpretive approach, which involves the collection and analysis of qualitative data in an ISO certified organization. The paper argues that structured process management provides a framework for organizations. However, we also observed that the attitude which surrounds process management is diverse inside an organization. Additionally, this framework results in positive effects as well as certain constraints for organizations. These constraints in turn affect its processes and innovations. Both intended and ingenuous actions occur as a response to these constraints. The creative potential of an organization helps to overcome the given constraints of structured process management. Therefore the paper claims that within a creative business environment such creative potential is essential.
Exploiting non-local features for spoken language understanding
Authors: Minwoo Jeong, Gary Geunbae Lee
Venue: Proceedings of the COLING/ACL on Main conference poster sessions (2006)

In this paper, we exploit non-local features as an estimate of long-distance dependencies to improve performance on the statistical spoken language understanding (SLU) problem. The statistical natural language parsers trained on text perform unreliably to encode non-local information on spoken language. An alternative method we propose is to use trigger pairs that are automatically extracted by a feature induction algorithm. We describe a light version of the inducer in which a simple modification is efficient and successful. We evaluate our method on an SLU task and show an error reduction of up to 27% over the base local model.
Aligning features with sense distinction dimensions
Authors: Nianwen Xue, Jinying Chen, Martha Palmer
Venue: Proceedings of the COLING/ACL on Main conference poster sessions (2006)

In this paper we present word sense disambiguation (WSD) experiments on ten highly polysemous verbs in Chinese, where significant performance improvements are achieved using rich linguistic features. Our system performs significantly better, and in some cases substantially better, than the baseline on all ten verbs. Our results also demonstrate that features extracted from the output of an automatic Chinese semantic role labeling system in general benefited the WSD system, even though the amount of improvement was not consistent across the verbs. For a few verbs, semantic role information actually hurt WSD performance. The inconsistency of feature performance is a general characteristic of the WSD task, as has been observed by others. We argue that this result can be explained by the fact that word senses are partitioned along different dimensions for different verbs and the features therefore need to be tailored to particular verbs in order to achieve adequate accuracy on verb sense disambiguation.
Gemini Lite: a non-intrusive debugger for Windows NT
Authors: Ryan S. Wallach
Venue: Proceedings of the 4th conference on USENIX Windows Systems Symposium - Volume 4 (2000)

It is frequently useful to debug a running software system in a production environment with a symbolic debugger without interfering with the operation of the system. The user of such a debugger may want to inspect data or trigger some data collecting operations whenever the running program hits an arbitrary address. Terminating or initiating the debugging session must also be transparent to users of the system. Debuggers available for Windows NT (or any debugger written with the Win32 debugging API) cannot detach from a running process without killing it, so they are unsuitable for debugging live systems. This paper presents the design of Gemini Lite, a debugger written without the Win32 debugger API, which has the capabilities needed to debug running production systems.
Review: On the statistical decorrelation of the wavelet packet coefficients of a band-limited wide-sense stationary random process
Authors: Abdourrahmane M. Atto, Dominique Pastor, Alexandru Isar
Venue: Signal Processing (2007)

This paper is a contribution to the analysis of the statistical correlation of the wavelet packet coefficients resulting from the decomposition of a random process, stationary in the wide-sense, whose power spectral density (PSD) is bounded with support in [-@p,@p]. Consider two quadrature mirror filters (QMF) that depend on a parameter r, such that these filters tend almost everywhere to the Shannon QMF when r increases. The parameter r is called the order of the QMF under consideration. The order of the Daubechies filters (resp. the Battle-Lemarie filters) is the number of vanishing moments of the wavelet function (resp. the spline order of the scaling function). Given any decomposition path in the wavelet packet tree, the wavelet packet coefficients are proved to decorrelate for every packet associated with a large enough resolution level, provided that the QMF order is large enough and above a value that depends on this wavelet packet. Another consequence of our derivation is that, when the coefficients associated with a given wavelet packet are approximately decorrelated, the value of the autocorrelation function of these coefficients at lag 0 is close to the value taken by the PSD of the decomposed process at a specific point. This specific point depends on the path followed in the wavelet packet tree to attain the wavelet packet under consideration. Some simulations highlight the good quality of the ''whitening'' effect that can be obtained in practical cases.

Venue: IEEE Distributed Systems Online (2007)

Many believe that multi-view video is poised to change how people watch television and that it could become a driving force in interactive multimedia entertainment, for both desktop and mobile environments. Owing to the massive amount of data involved and extensive processing requirements, real-time MVV processing presents research issues that lie at the frontier of video coding, image processing, computer vision, and display technologies.
A Case Study of Defect-Density and Change-Density and their Progress over Time
Authors: Anita Gupta, Odd Petter N. Slyngstad, Reidar Conradi, Parastoo Mohagheghi, Harald Ronneberg, Einar Landre
Venue: Proceedings of the 11th European Conference on Software Maintenance and Reengineering (2007)

We have performed an empirical case study, investigating defect-density and change-density of a reusable framework compared with one application reusing it over time at a large Oil and Gas company in Norway, Statoil ASA. The framework, called JEF, consists of seven components grouped together, and the application, called DCF, reuses the framework, without modifications to the framework. We analyzed all trouble reports and change requests from three releases of both. Change requests in our study covered any changes (not correcting defects) in the requirements, while trouble reports covered any reported defects. Additionally, we have investigated the relation between defect-density and change-density both for the reusable JEF framework and the application. The results revealed that the defectdensity of the reusable framework was lower than the application. The JEF framework had higher changedensity in the first release, but lower change-density than the DCF application over the successive releases. For the DCF application, on the other hand, a slow increase in change-density appeared. On the relation between change-density and defect-density for the JEF framework, we found a decreasing defect-density and change-density. The DCF application here showed a decreasing defect-density, with an increasing changedensity. The results show that the quality of the reusable framework improves and it becomes more stable over several releases, which is important for reliability of the framework and assigning resources.
Implementing Network Partition-Aware Fault-Tolerant CORBA Systems
Authors: Stefan Beyer, Francesc D. Munoz-Esco, Pablo Galdamez
Venue: Proceedings of the The Second International Conference on Availability, Reliability and Security (2007)

The current standard for Fault-Tolerance in the Common Object Request Broker Architecture (CORBA) does not support network partitioning. However, distributed systems, and those deployed on wide area networks in particular, are susceptible to network partitions. The contribution of this paper is the description of the design and implementation of a CORBA fault-tolerance add-on for partitionable environments. Our solution can be applied to an off-the-shelf Object Request Broker, without having access to the ORB's source code and with minimal changes to existing CORBA applications. The system distinguishes itself from existing solutions in the way different replication and reconciliation strategies can be implemented easily. Furthermore, we provide a novel replication and reconciliation protocol that increases the availability of systems, by allowing operations in all partitions to continue.
Set partitioning in oblivious data hiding
Authors: Litao Gang
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2001. on IEEE International Conference - Volume 03 (2001)

In oblivious steganography, host noise suppression is a great concern as the watermark signal energy is usually much less than that of the host signal. We model the data hiding as a more general H0/H1 hypothesis testing problem. Decision making is based on the statistical distinction between H0 and H1. A simple embedding scheme, viz., set partitioning, is proposed. The coefficients are divided into two sets to represent bit value 1 and 0. The average distortion introduced is calculated. Its optimum and suboptimal detection is discussed in detail. Analysis and simulation studies show improvement over existing schemes.
"Live and Learn" program for recruitment/retention
Authors: W. L. Cooley
Venue: Proceedings of the Frontiers in Education Conference,1997. on 27th Annual Conference. Teaching and Learning in an Era of Change. - Volume 01 (1997)

Recent trends in education have caused universities and colleges to invest considerable effort into recruitment and retention of students. This paper describes a pilot program at West Virginia University, USA, called "Live and Learn". The essence of the program is to cluster beginning students with the same major (such as engineering) together in the residence hall and to schedule them into the same section of several of their freshman classes. Other measures are taken to provide academic support and foster a sense of community. After one year, the authors report that the program has been a great success in retaining freshman engineering students. It seems to have helped improve their recruiting record for next year as well.
The extended least-squares and the joint maximum-a-posteriori maximum-likelihood estimation criteria
Authors: A. Yeredor
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 04 (1999)

Approximate model equations often relate given measurements to unknown parameters whose estimate is sought. The least-squares (LS) estimation criterion assumes the measured data to be exact, and seeks parameters which minimize the model errors. Existing extensions of LS, such as the total LS (TLS) and constrained TLS (CTLS) take the opposite approach, namely assume the model equations to be exact, and attribute all errors to measurement inaccuracies. We introduce the extended LS (XLS) criterion, which accommodates both error sources. We define 'pseudo-linear' models, with which we provide an iterative algorithm for minimization of the XLS criterion. Under certain statistical assumptions, we show that XLS coincides with a statistical criterion, which we term the 'joint maximum-a-posteriori-maximum-likelihood' (JMAP-ML) criterion. We identify the differences between the JMAP-ML and ML criteria, and explain the observed superiority of JMAP-ML over ML under non-asymptotic conditions.
