A Mathematical Model for Performability of Beowulf Clusters
Authors: Enver Ever, Orhan Gemikonakli, Ram Chakka
Venue: Proceedings of the 39th annual Symposium on Simulation (2006)

Beowulf clusters have become very popular as an alternative to supercomputers world-wide. However, the most pressing issues of today's cluster solutions is the need for high availability and performance. Such systems, clearly, are prone to break-downs. Even if cover is provided with some probability c, there will be reconfiguration and/or rebooting delays to resume the operation of a cluster. In this paper, the performance modelling for Beowulf multiprocessor systems is presented. For these systems, one head processor and several identical processors serving a common stream of arriving jobs is considered. To account for delays due to reconfiguration and rebooting, such systems are modelled and solved for exact performability measures, for both bounded and unbounded queuing capacities, using the spectral expansion method.
Designing Embedded Hardware
Authors: John Catsoulis
Venue:  (2005)

Embedded computer systems literally surround us: they're in our cell phones, PDAs, cars, TVs, refrigerators, heating systems, and more. In fact, embedded systems are one of the most rapidly growing segments of the computer industry today. Along with the growing list of devices for which embedded computer systems are appropriate, interest is growing among programmers, hobbyists, and engineers of all types in how to design and build devices of their own. Furthermore, the knowledge offered by this book into the fundamentals of these computer systems can benefit anyone who has to evaluate and apply the systems. The second edition of Designing Embedded Hardware has been updated to include information on the latest generation of processors and microcontrollers, including the new MAXQ processor. If you're new to this and don't know what a MAXQ is, don't worry--the book spells out the basics of embedded design for beginners while providing material useful for advanced systems designers. Designing Embedded Hardware steers a course between those books dedicated to writing code for particular microprocessors, and those that stress the philosophy of embedded system design without providing any practical information. Having designed 40 embedded computer systems of his own, author John Catsoulis brings a wealth of real-world experience to show readers how to design and create entirely new embedded devices and computerized gadgets, as well as how to customize and extend off-the-shelf systems. Loaded with real examples, this book also provides a roadmap to the pitfalls and traps to avoid. Designing Embedded Hardware includes: The theory and practice of embedded systems Understanding schematics and data sheets Powering an embedded system Producing and debugging an embedded system Processors such as the PIC, Atmel AVR, and Motorola 68000-series Digital Signal Processing (DSP) architectures Protocols (SPI and I2C) used to add peripherals RS-232C, RS-422, infrared communication, and USB CAN and Ethernet networking Pulse Width Monitoring and motor control If you want to build your own embedded system, or tweak an existing one, this invaluable book gives you the understanding and practical skills you need.
Damon: a decentralized aspect middleware built on top of a peer-to-peer overlay network
Authors: Rubén Mondéjar, Pedro García, Carles Pairot, Antonio F. Gómez Skarmeta
Venue: Proceedings of the 6th international workshop on Software engineering and middleware (2006)

In this paper we present Damon, a decentralized wide-area runtime aspect middleware built on top of a structured peer-to-peer (p2p) substrate and a dynamic Aspect Oriented Programming (AOP) framework. By using this methodology, we provide innovative benefits like aspect persistence and discovery, a high performance one-to-one/one-to-many messaging system, reflective skills, and a decentralized aspect container. Furthermore, new pointcut abstractions (anypointcut, manypointcut and multipointcut) are introduced, which allow development of shared aspect functionalities in a transparent way. We believe that such middleware is a novel solution for allowing decentralized crosscutting concerns like fault-tolerance or load-balancing for distributed systems. This paper describes these ideas and it presents a use case of our middleware implementation.
Topological and geometric beautification of reverse engineered geometric models
Authors: F. C. Langbein, C. H. Gao, B. I. Mills, A. D. Marshall, R. R. Martin
Venue: Proceedings of the ninth ACM symposium on Solid modeling and applications (2004)

Boundary representation models reverse engineered from 3D range data suffer from various inaccuracies caused by noise in the measured data and the model building software. Beautification aims to improve such models in a post-processing step solely working with the boundary representation model. The improved model should exhibit topological and geometric regularities representing the original, ideal design intent. This paper gives an overview of algorithms for a complete beautification system suitable for improving the topology and the geometry of low to medium complexity reverse engineered models.
Security Checkpoint Optimizer (SCO): an application for simulating the operations of airport security checkpoints
Authors: Diane Wilson, Eric K. Roe, S. Annie So
Venue: Proceedings of the 38th conference on Winter simulation (2006)

For most security planners, a key challenge is to continuously evaluate how changes or additions to their facilities or procedures impact security effectiveness, operational costs, and passenger throughput. Each change must be analyzed to ensure negative effects do not outweigh the benefits. This paper presents Security Checkpoint Optimizer (SCO), a 2-D spatially aware discrete event simulation tool developed by Northrop Grumman for the Transportation Security Administration (TSA), a part of the U.S. Department of Homeland Security. SCO is designed to allow security analysts to graphically build a simulation model and layout a series of screening activities to take place. Once the model is defined, SCO simulates passenger movement using both path-based and pathless movement algorithms to mimic a semi-autonomous passenger traversal of a 2-D space. The software is designed to allow analysts to perform multiple "what-if" analyses to balance benefits and tradeoffs.
Free Iris and Focus Image Generation by Merging Multiple Differently Focused Images Based on a Three-Dimensional Filtering
Authors: Kazuya Kodama, Akira Kubota
Venue: IEICE - Transactions on Information and Systems (2007)

This paper describes a method of free iris and focus image generation based on transformation integrating multiple differently focused images. First, we assume that objects are defocused by a geometrical blurring model. And we combine acquired images on certain imaging planes and spatial information of objects by using a convolution of a three-dimensional blur. Then, based on spatial frequency analysis of the blur, we design three-dimensional filters that generate free iris and focus images from the acquired images. The method enables us to generate not only an all-in-focus image corresponding to an ideal pin-hole iris but also various images, which would be acquired with virtual irises whose sizes are different from the original one. In order to generate a certain image by using multiple differently focused images, especially very many images, conventional methods usually analyze focused regions of each acquired image independently and construct a depth map. Then, based on the map, the regions are merged into a desired image with some effects. However, generally, it is so difficult to conduct such depth estimation robustly in all regions that these methods cannot prevent merged results from including visible artifacts, which decrease the quality of generated images awfully. In this paper, we propose a method of generating desired images directly and robustly from very many differently focused images without depth estimation. Simulations of image generation are performed utilizing synthetic images to study how certain parameters of the blur and the filter affect the quality of generated images. We also introduce pre-processing that corrects the size of acquired images and a simple method for estimating the parameter of the three-dimensional blur. Finally, we show experimental results of free iris and focus image generation from real images.

Hallucinating multiple occluded face images of different resolutions
Authors: Kui Jia, Shaogang Gong
Venue: Pattern Recognition Letters (2006)

Learning-based super-resolution has recently been proposed for enhancing human face images, known as ''face hallucination''. In this paper, we propose a novel algorithm to super-resolve face images given multiple partially occluded inputs at different lower resolutions. By integrating hierarchical patch-wise alignment and inter-frame constraints into a Bayesian framework, we can probabilistically align multiple input images at different resolutions and recursively infer the high-resolution face image. We address the problem of fusing partial imagery information through multiple frames and discuss the new algorithm's effectiveness when encountering occluded low-resolution face images. We show promising results compared to those of existing face hallucination methods from both simulated facial database and live video sequences.
Some Equivalences between Kernel Methods and Information Theoretic Methods
Authors: Robert Jenssen, Torbjørn Eltoft, Deniz Erdogmus, Jose C. Principe
Venue: Journal of VLSI Signal Processing Systems (2006)

In this paper, we discuss some equivalences between two recently introduced statistical learning schemes, namely Mercer kernel methods and information theoretic methods. We show that Parzen window-based estimators for some information theoretic cost functions are also cost functions in a corresponding Mercer kernel space. The Mercer kernel is directly related to the Parzen window. Furthermore, we analyze a classification rule based on an information theoretic criterion, and show that this corresponds to a linear classifier in the kernel space. By introducing a weighted Parzen window density estimator, we also formulate the support vector machine in this information theoretic perspective.
Improved quality of reconstructed images using floating point arithmetic for moment calculation
Authors: Chandan Singh
Venue: Pattern Recognition (2006)

Zernike moments which are superior to geometric moments because of their special properties of image reconstruction and immunity to noise, suffer from several discretization errors. These errors lead to poor quality of reconstructed image and wide variations in the numerical values of the moments. The predominant factor, as observed in this paper, is due to the discrete integer implementation of the steps involved in moment calculation. It is shown in this paper that by modifying the algorithms to include discrete float implementation, the quality of the reconstructed image improves significantly and the first-order moment becomes zero. Low-order Zernike moments have been found to be stable under linear transformations while the high-order moments have large variations. The large variations in high-order moments, however, do not greatly affect the quality of the reconstructed image, implying that they should be ignored when numerical values of moments are used as features. The 11 functions based on geometric moments have also been found to be stable under linear transformations and thus these can be used as features. Pixel level analysis of the images has been carried out to strengthen the results.
QOMA: quasi-optimal multiple alignment of protein sequences
Authors: Xu Zhang, Tamer Kahveci
Venue: Bioinformatics (2007)

Motivation: We consider the problem of multiple alignment of protein sequences with the goal of achieving a large SP (Sum-of-Pairs) score. Results: We introduce a new graph-based method. We name our method QOMA (Quasi-Optimal Multiple Alignment). QOMA starts with an initial alignment. It represents this alignment using a K-partite graph. It then improves the SP score of the initial alignment through local optimizations within a window that moves greedily on the alignment. QOMA uses two parameters to permit flexibility in time/accuracy trade off: (1) The size of the window for local optimization. (2) The sparsity of the K-partite graph. Unlike traditional progressive methods, QOMA is independent of the order of sequences. The experimental results on BAliBASE benchmarks show that QOMA produces higher SP score than the existing tools including ClustalW, Probcons, Muscle, T-Coffee and DCA. The difference is more significant for distant proteins. Availability: The software is available from the authors upon request.

Tracing surface intersections with validated ODE system solver
Authors: H. Mukundan, K. H. Ko, T. Maekawa, T. Sakkalis, N. M. Patrikalakis
Venue: Proceedings of the ninth ACM symposium on Solid modeling and applications (2004)

This paper presents a robust method for tracing intersection curve segments between continuous rational parametric surfaces, typically rational polynomial parametric surface patches. The tracing procedure is based on a validated ordinary differential equation (ODE) system solver which can be applied, without substantial overhead, for transversal as well as tangential intersections. Application of the validated ODE solver in the context of eliminating the phenomenon of straying and looping is discussed. In addition, we develop a method to fulfill the condition of a continuous gap-free boundary with a definite numerically verified upper bound for the intersection curve error in parameter space and is further mapped to an upper bound for the intersection curve error in 3D model space, which assists in defining well-formed boundary representation models of complex 3D solids.

Venue:  (2005)

In a typical organization, there's always plenty that to do such as: pay vendors, invoice customers, answer customer inquiries, and fix bugs in hardware or software. You need to know who wants what and keep track of what is left to do. This is where a ticketing system comes in. A ticketing system allows you to check the status of various tasks: when they were requested, who requested them and why, when they were completed, and more. RT is a high-level, open source ticketing system efficiently enabling a group of people to manage tasks, issues, and requests submitted by a community of users.RT Essentials, co-written by one of the RT's original core developers, Jesse Vincent, starts off with a quick background lesson about ticketing systems and then shows you how to install and configure RT. This comprehensive guide explains how to perform day-to-day tasks to turn your RT server into a highly useful tracking tool. One way it does this is by examining how a company could use RT to manage its internal processes. Advanced chapters focus on developing add-on tools and utilities using Perl and Mason. There's also chapter filled with suggested uses for RT inside your organization.No matter what kind of data your organization tracks--from sales inquiries to security incidents or anything in between--RT Essentials helps you use RT to provide order when you need it most.
Part family formation through fuzzy ART2 neural network
Authors: R. J. Kuo, Y. T. Su, C. Y. Chiu, Kai-Ying Chen, F. C. Tien
Venue: Decision Support Systems (2006)

In order to overcome some unavoidable factors, like shift of the part, that influence the crisp neural networks' recognition, the present study is dedicated in developing a novel fuzzy neural network (FNN), which integrates both the fuzzy set theory and adaptive resonance theory 2 (ART2) neural network for grouping the parts into several families based on the image captured from the Vision sensor. The proposed network posses the fuzzy inputs as well as the fuzzy weights. The model evaluation results showed that the proposed fuzzy neural network is able to provide more accurate results compared to the fuzzy self-organizing feature maps (SOM) neural network [R.J. Kuo, S.S. Chi, P.W. Teng, Generalized part family formation through fuzzy self-organizing feature map neural network, International Journal of Computers in Industrial Engineering, 40 (2001b) 79-100] and fuzzy c-means algorithm.
From COURSEWRITER to APL to ???

Venue: ACM SIGCUE Outlook (1975)

One of the advantages of small size is presumably the ability to rapidly shift position as the need becomes apparent -- and, in the field of computer-assisted instruction, to evolve flexibly with the state-of-the-art without being burdened by the inertia of long-established and deeply entrenched prior practice. If this is true, then Simon Fraser's CAI effort, certainly one of the smaller ones in terms of people, would seem to be exploiting its size to the utmost.
