An XML-based Synchronization of Audio and Graphical Representations of Music Scores
Authors: Adriano Barate, Luca A. Ludovico
Venue: Proceedings of the Eight International Workshop on Image Analysis for Multimedia Interactive Services (2007)

This paper presents an overview on a future IEEE standard aimed at providing an overall description of music. This format, known as IEEE PAR1599, is based on the XML meta-language. Its purpose is taking into account the heterogeneous multimedia representations of music, such as audio tracks, video clips and graphical instances of score. The key characteristics of the format are the possibility to enjoy such heterogeneous contents in a synchronized way and the possibility to switch from a particular representation to another in real-time. After a short description of the particular XML language we have adopted, a case study will be presented: an application installed at the exhibition "Celeste Aida" held at Teatro alla Scala in November 2006 - January 2007.
Designing extensible IP router software
Authors: Mark Handley, Eddie Kohler, Atanu Ghosh, Orion Hodson, Pavlin Radoslavov
Venue: Proceedings of the 2nd conference on Symposium on Networked Systems Design & Implementation - Volume 2 (2005)

Many problems with today's Internet routing infrastructure--slow BGP convergence times exacerbated by timer-based route scanners, the difficulty of evaluating new protocols--are not architectural or protocol problems, but software problems. Router software designers have tackled scaling challenges above all, treating extensibility and latency concerns as secondary. At this point in the Internet's evolution, however, further scaling and security issues require tackling latency and extensibility head-on. We present the design and implementation of XORP, an IP routing software stack with strong emphases on latency, scaling, and extensibility. XORP is event-driven, and aims to respond to routing changes with minimal delay--an increasingly crucial requirement, given rising expectations for Internet reliability and convergence time. The XORP design consists of a composable framework of routing processes, each in turn composed of modular processing stages through which routes flow. Extensibility and latency concerns have influenced XORP throughout, from IPC mechanisms to process arrangements to intra-process software structure, and leading to novel designs. In this paper we discuss XORP's design and implementation, and evaluate the resulting software against our performance and extensibility goals.
Cad tools for dna micro-array design, manufacture and application
Authors: Alexander Zelikovsky
Venue:  (2006)

Motivation. As the human genome project progresses and some microbial and eukaryotic genomes are recognized, numerous biotechnological processes have attracted increasing number of biologists, bioengineers and computer scientists recently. Biotechnological processes profoundly involve production and analysis of high-throughput experimental data. Numerous sequence libraries of DNA and protein structures of a large number of micro-organisms and a variety of other databases related to biology and chemistry are available. For example, microarray technology, a novel biotechnology, promises to monitor the whole genome at once, so that researchers can study the whole genome on the global level and have a better picture of the expressions among millions of genes simultaneously. Today, it is widely used in many fields---disease diagnosis, gene classification, gene regulatory network, and drug discovery. For example, designing organism specific microarray and analysis of experimental data require combining heterogeneous computational tools that usually differ in the data format; such as, GeneMark for ORF extraction, Promide for DNA probe selection, Chip for probe placement on microarray chip, BLAST to compare sequences, MEGA for phylogenetic analysis, and ClustalX for multiple alignments. Solution. Surprisingly enough, despite huge research efforts invested in DNA array applications, very few works are devoted to computer-aided optimization of DNA array design and manufacturing. Current design practices are dominated by ad-hoc heuristics incorporated in proprietary tools with unknown suboptimality. This will soon become a bottleneck for the new generation of high-density arrays, such as the ones currently being designed at Perlegen [109]. The goal of the already accomplished research was to develop highly scalable tools, with predictable runtime and quality, for cost-effective, computer-aided design and manufacturing of DNA probe arrays. We illustrate the utility of our approach by taking a concrete example of combining the design tools of microarray technology for Harpes B virus DNA data.
Graphical dictionaries and the memorable space of graphical passwords
Authors: Julie Thorpe, P. C. van Oorschot
Venue: Proceedings of the 13th conference on USENIX Security Symposium - Volume 13 (2004)

In commonplace textual password schemes, users choose passwords that are easy to recall. Since memorable passwords typically exhibit patterns, they are exploitable by brute-force password crackers using attack dictionaries. This leads us to ask what classes of graphical passwords users find memorable. We postulate one such class supported by a collection of cognitive studies on visual recall, which can be characterized as mirror symmetric (reflective) passwords. We assume that an attacker would put this class in an attack dictionary for graphical passwords and propose how an attacker might order such a dictionary. We extend the existing analysis of graphical passwords by analyzing the size of the mirror symmetric password space relative to the full password space of the graphical password scheme of Jermyn et al. (1999), and show it to be exponentially smaller (assuming appropriate axes of reflection). This reduction in size can be compensated for by longer passwords: the size of the space of mirror symmetric passwords of length about L + 5 exceeds that of the full password space for corresponding length L ≤ 14 on a 5 × 5 grid. This work could be used to help in formulating password rules for graphical password users and in creating proactive graphical password checkers.
Analysis of Irregularities in Human Actions with Volumetric Motion History Images
Authors: Alexandra Branzan Albu, Trevor Beugeling, Naznin Virji-Babul, Cheryl Beach
Venue: Proceedings of the IEEE Workshop on Motion and Video Computing (2007)

This paper describes a new 3D motion representation, the Volumetric Motion History Image (VMHI), to be used for the analysis of irregularities in human actions. Such irregularities may occur either in speed or orientation and are strong indicators of the balance abilities and of the confidence level of the subject performing the activity. The proposed VMHI representation overcomes limits of the standard MHI related to motion self-occlusion and speed and is therefore suitable for the visualization and quantification of abnormal motion. This work focuses on the analysis of sway, which is the most common motion irregularity in the studied set of human actions. The sway is visualized and quantified via a user interface using a measure of spatiotemporal surface smoothness, namely the deviation vector. Experimental results show that the deviation vector is a reliable measure for quantifying the deviation of abnormal motion from its corresponding normal motion.
Visualising A Skeletal Dysplasia Knowledgebase
Authors: Ingrid B. Jakobsen, Theodor G. Wyeld, David P. Hansen, Andreas Zankl
Venue: Proceedings of the International Conference on Medical Information Visualisation - BioMedical Visualisation (2007)

Skeletal dysplasias affect around 4 million people worldwide. Various nosologies exist for describing and classifying their clinical, radiological, and genetic features. A methodological framework is needed to establish a single consolidated nosology for skeletal dysplasias based on the existing multiple classification systems.. Once established, the terms used can be linked to an existing database of exemplar x-ray images and explored interactively. As a proof-of-concept, a pilot study was conducted to investigate the potential in both establishing a consolidated nosology and visualisation of the results. This paper reports on a preliminary methodological framework for proceeding and initial visualisation results which go some way towards demonstrating the potential of such a system. The aim of this project is to assist clinicians to make more accurate diagnoses of skeletal dysplasias and to foster translational research. This is set against the background of an existing unwieldy classification system.
Adaptive Image Segmentation Based on Fast Thresholding and Image Merging
Authors: Ye Zhang, Hongsong Qu, Yanjie Wang
Venue: Proceedings of the 16th International Conference on Artificial Reality and Telexistence--Workshops (2006)

Image segmentation is the first essential and important step of low level vision. This paper proposes a novel algorithm for adaptive image segmentation, based on thresholding technique and segments merging according to their characteristics combine with spatial position. Our earlier work of getting the entire information of the histogram could help choose the multiple thresholds. However, not all the peaks of the histogram correspond to obvious structural unit in the image. Spatial information must be involved. This paper also suggests subjoining segments matching for video image tracking. They will give great help to image segmentation. The proposed algorithm can meet the real-time requirement and lead to higher segmentation accuracy, some types of texture can also be segmented well; it can be applied in many conditions, including complex target segmented. We describe the algorithm in detail and perform simulation experiments. The computation based on pixels can fully parallel processing to save time.
Restraint Order Component Model Execution
Authors: Andreea Vescan
Venue: Proceedings of the Eighth International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (2006)

In this paper we discuss a way of composing a system from components and two different execution approaches of the obtained solutions. Secondly, we argue that the selection of the accurate model that best represents the user requirements supposes semantic involvement by the user. We illustrate the synergy of model construction and model execution by giving a real life example. The integration of an automatic composition model has validated our approach as a simple but powerful tool for customizing software to support client-specific requirements.
Obfuscating document stylometry to preserve author anonymity
Authors: Gary Kacmarcik, Michael Gamon
Venue: Proceedings of the COLING/ACL on Main conference poster sessions (2006)

This paper explores techniques for reducing the effectiveness of standard authorship attribution techniques so that an author A can preserve anonymity for a particular document D. We discuss feature selection and adjustment and show how this information can be fed back to the author to create a new document D' for which the calculated attribution moves away from A. Since it can be labor intensive to adjust the document in this fashion, we attempt to quantify the amount of effort required to produce the anonymized document and introduce two levels of anonymization: shallow and deep. In our test set, we show that shallow anonymization can be achieved by making 14 changes per 1000 words to reduce the likelihood of identifying A as the author by an average of more than 83%. For deep anonymization, we adapt the unmasking work of Koppel and Schler to provide feedback that allows the author to choose the level of anonymization.

Analysis of MPLS Signaling Protocols and Traffic Dissemination in OSPF and MPLS
Authors: Sang-Chul Kim, Jong-Moon Chung
Venue: Proceedings of the First Asia International Conference on Modelling & Simulation (2007)

This paper analyzes MPLS signaling protocols for traffic engineering, shows the capability of providing traffic engineering in MPLS compared to the conventional routing protocol, and explains the MPLS LSR operations based on the basic LSR functionality of classification, queue, and scheduling. CR-LDP, RSVP and RSVP-TE are summarized and analyzed based on how to set up LSP for TE with help of protocol messages. In addition, the comparisons of CR-LDP, RSVP, and RSVP-TE are conducted based on the aspects of LSP reliability and LSP adaptability. A performance metric such as throughput is adopted in order to measure the capability of MPLS traffic engineering based on computer-based simulation.
Optimizing a design based undergraduate power engineering education program
Authors: J. A. Momoh
Venue: Proceedings of the 26th Annual Frontiers in Education - Volume 01 (1996)

Howard University is continually renewing its engineering program for fast integration of new and developing technologies. The continuing effort is to further incorporate design in the curriculum up-date of undergraduate engineering programs. The objective is to make our products more competitive in the new world and labor environment. This philosophy has been applied to a traditional electrical engineering option, the electric power engineering program, which had been experiencing decreasing intake. This paper presents a success story at optimizing a design based undergraduate power engineering education program at Howard University. The basic philosophy, methodology and results obtained are discussed. Sample projects carried out by students are briefly presented and these demonstrate the broad base and multi-disciplinary nature of the design projects. These design projects include 'Integrated Optimal Power Flow and Dynamic Security Design', 'Hybrid Transit Electric Vehicle', and 'Medicine Bottle Opener'. The overall effect has been to improve professionalism and problem solving skills and increase self esteem of students, and thereby, their productivity. It has heightened interest and awareness of the electric power program, increased both the number of students graduating in the electrical power program and the retention ratio. The lessons learnt will be of value to other engineering schools.
ANIQUE+: A new American national standard for non-intrusive estimation of narrowband speech quality: Research Articles
Authors: Doh-Suk Kim, Ahmed Tarraf
Venue: Bell Labs Technical Journal (2007)

Non-intrusive estimation of speech quality is a challenging problem in that the estimation has to be performed without the original reference speech signals. This paper presents a new American national standard (ANS) for non-intrusive estimation of narrowband speech quality. The proposed auditory non-intrusive quality estimation plus (ANIQUE) model is a perceptual model simulating the functional roles of the human auditory system and employs improved modeling of quality estimation by a statistical learning paradigm. Experimental evaluation demonstrated that the performance of the ANIQUE model is significantly superior to that of the current International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) standard recommendation P.563 on 34 different subjective mean opinion score (MOS) databases. &copy; 2007 Alcatel-Lucent.
Model Analysis Geometry Imagery Correlation Tool Kit (MAGIC-TK) for Model Development and Image Analysis
Authors: Thomas M. Taczak, Matthew Rundquist, Colin P. Cahill
Venue: Proceedings of the 35th Applied Imagery and Pattern Recognition Workshop (2006)

The application of IR signature prediction codes in DoD has been predominantly in two areas: 1.) the development of total signature requirements under a broad set of environmental and operational conditions and 2.) the evaluation of signatures of vessels and signature treatments to ensure the specifications are met. As computing power and IR scene generation techniques have advanced, simulation capabilities have evolved to scene injection into real hardware systems. To capture the real world effects required to accurately analyze search and track algorithms, the fidelity of the complete IR scene has required improvement. New validation methodologies are required to evaluate the accuracy of advanced IR scene generation models. This paper will review some of the approaches incorporated into a new model validation tool that will be able to verify model inputs and quantitatively evaluate differences between measured and predicted imagery.
Physical simulation for animation and visual effects: parallelization and characterization for chip multiprocessors
Authors: Christopher J. Hughes, Radek Grzeszczuk, Eftychios Sifakis, Daehyun Kim, Sanjeev Kumar, Andrew P. Selle, Jatin Chhugani, Matthew Holliman, Yen-Kuang Chen
Venue: ACM SIGARCH Computer Architecture News (2007)

We explore the emerging application area of physics-based simulation for computer animation and visual special effects. In particular, we examine its parallelization potential and characterize its behavior on a chip multiprocessor (CMP). Applications in this domain model and simulate natural phenomena, and often direct visual components of motion pictures. We study a set of three workloads that exemplify the span and complexity of physical simulation applications used in a production environment: fluid dynamics, facial animation, and cloth simulation. They are computationally demanding, requiring from a few seconds to several minutes to simulate a single frame; therefore, they can benefit greatly from the acceleration possible with large scale CMPs. Starting with serial versions of these applications, we parallelize code accounting for at least 96% of the serial execution time, targeting a large number of threads.We then study the most expensive modules using a simulated 64-core CMP. For the code representing key modules, we achieve parallel scaling of 45x, 50x, and 30x for fluid, face, and cloth simulations, respectively. The modules have a spectrum of parallel task granularity and locking behavior, and all but one are dominated by loop-level parallelism. Many modules operate on streams of data. In some cases, modules iterate over their data, leading to significant temporal locality. This streaming behavior leads to very high on-die and main memory bandwidth requirements. Finally, most modules have little inter-thread communication since they are data-parallel, but a few require heavy communication between data-parallel operations.
Teaching graduate teaching assistants (GTAs) how to teach
Authors: L. G. Richards
Venue: Proceedings of the 30th Annual Frontiers in Education - Volume 02 (2000)

From 1992 to 1998, an Engineering Concepts course was taught to first year students at the University of Virginia (UVa). In that time, enrolments increased from 250 students to over 500 each fall. As the course grew, we employed a team of graduate teaching assistants (GTAs) to provide individual and small group learning experiences. Over 50 students served as GTAs during the life of the course. They varied greatly in communication skills and teaching effectiveness. From 1994 to 1998, we compiled data on all aspects of this course, including ratings for individual faculty and GTAs. What makes a successful GTA? Why do some students fail to perform well? We reflect on our experiences with these graduate students and their contributions to this course. We also report the results of surveys of their students. There were some surprises, faculty members cannot always predict who will do well and who will fail as teachers. The issues raised by the undergraduate students in evaluating their GTAs are not always what we expect.
Glottal flow derivative modeling with the wavelet smoothed excitation
Authors: A. P. Lobo
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 200. on IEEE International Conference - Volume 02 (2001)

This paper discusses a method for estimating glottal flow derivative model parameters using wavelet-smoothed excitation. The excitation is first estimated using the weighted recursive least squares with variable forgetting factor algorithm. The raw excitation is then smoothed by applying a discrete wavelet transform (DWT) using biorthogonal quadrature filters, and a thresholding operation carried out on the DWT amplitude coefficients, followed by an inverse DWT. The pitch period and the instant of glottal closure (IGC) are estimated from the wavelet-smoothed excitation. A six-parameter glottal flow derivative model consisting of three amplitude and three timing parameters is aligned with the IGC and optimized by minimum square error fitting to the speech waveform. The optimization is done by the method of simulated annealing. The. model is then used to reestimate the vocal-tract filter parameters in an ARX procedure followed by further stages of voice source-vocal tract estimation. The results of analysis of speech utterances from the BK TIMIT database are presented. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

SDRAM Delay Fault Modeling and Performance Testing
Authors: Yu-Tsao Hsing, Chun-Chieh Huang, Jen-Chieh Yeh, Cheng-Wen Wu
Venue: Proceedings of the 25th IEEE VLSI Test Symmposium (2007)

DRAM timing parameter testing has always been considered a time-consuming process. This paper presents a systematic approach to analysis and classification of the synchronous DRAM (SDRAM) delay failure modes. Four delay fault models with March expression are proposed to cover important DRAM timing parameters. By at-speed March testing of these four types of delay faults, we can verify the DRAM timing specifications.
