Accuracy-aware SRAM: a reconfigurable low power SRAM architecture for mobile multimedia applications
Authors: Minki Cho, Jason Schlessman, Wayne Wolf, Saibal Mukhopadhyay
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

We propose a dynamically reconfigurable SRAM architecture for low-power mobile multimedia applications. Parametric failures due to manufacturing variations limit the opportunities for power saving in SRAM. We show that, using a lower voltage for cells storing low-order bits and a nominal voltage for cells storing higher order bits, ~45% savings in memory power can be achieved with a marginal (~10%) reduction in image quality. A reconfigurable array structure is developed to dynamically reconfigure the number of bits in different voltage domains.
MotifMap

Venue: Bioinformatics (2009)

Motivation: Achieving a comprehensive map of all the regulatory elements encoded in the human genome is a fundamental challenge of biomedical research. So far, only a small fraction of the regulatory elements have been characterized, and there is great interest in applying computational techniques to systematically discover these elements. Such efforts, however, have been significantly hindered by the overwhelming size of non-coding DNA regions and the statistical variability and complex spatial organizations of mammalian regulatory elements. Results: Here we combine information from multiple mammalian genomes to derive the first fairly comprehensive map of regulatory elements in the human genome. We develop a procedure for identifying regulatory sites, with high levels of conservation across different species, using a new scoring scheme, the Bayesian branch length score (BBLS). Using BBLS, we predict 1.5 million regulatory sites, corresponding to 380 known regulatory motifs, with an estimated false discovery rate (FDR) of <50%. We demonstrate that the method is particularly effective for 155 motifs, for which 121 056 sites can be mapped with an estimated FDR of <10%. Over 28K SNPs are located in regions overlapping the 1.5 million predicted motif sites, suggesting potential functional implications for these SNPs. We have deposited these elements in a database and created a user-friendly web server for the retrieval, analysis and visualization of these elements. The initial map provides a systematic view of gene regulation in the genome, which will be refined as additional motifs become available.

Reviving the Living, Volume 6: Meaning Making in Living Systems
Authors: Yair Neuman
Venue: Studies In Multidisciplinarity (2008)

Modern biology portrays living systems, from the amoeba to the human organism, as mechanical toys shaped by the brute logic of natural selection. In "Reviving the Living": Meaning Making in Living Systems, Dr. Yair Neuman challenges the dogmas that frame our understanding of living systems and presents an alternative that avoids the pitfalls of non-scientific perspectives such as Vitalism and Creationism. In this thought provoking and iconoclastic manuscript, Dr. Neuman follows the footsteps of Gregory Bateson, Mikhail Bakhtin, Michael Polanyi and others, to suggest that living systems are "meaning making" systems. Dr. Neuman delves into the unique processes of meaning making that characterize organisms as a unique category of nature, and presents new and fascinating insights into a variety of enigmatic biological phenomena from immune memory to hidden life (cryptobiosis). Written by a polymath, Reviving the Living is a tour-de-force in interdisciplinary research which is of high interest to any reflective individual who is willing to examine the realm of the living from a novel and fascinating perspective.* Presents a novel perspective that relates to current biological knowledge and issues* Poses thought provoking ideas for theoretical biologists, those studying philosophy of science and the mind, cognitive scientists, semioticians, and people involved with Artificial Intelligence. * Includes examples based in current science to illustrate core concepts and themes
Design and Implementation of Real-time Video Compression System Control Framework
Authors: Li Xiaoli, Liu Chao, Wang Qiang, Ding Wenrui
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 02 (2009)

In order to implement the real-time video compression system, the compression algorithm should be improved and also need a reasonable control framework which brings no additional overhead and efficient to use of the hardware resources. With the perspective of improve the degree of parallelism of the on-chip peripherals and the core, this paper analyzed the disadvantages of the ping-pong buffers pipeline mechanism at first, and then introduced a improved control framework based on dual-core DSP polling control and ping-pong buffers pipeline to avoid that disadvantages. A H.264 based video encoder used this control framework was implemented on the platform of ADSP-BF561, and the experimental results show that the framework can meet the video compression system’s real-time capability and reliability requirements by reducing the coding time、 falling the frame loss frequency and improving the system's work efficiency.
A new methodology of mobile robot navigation: The agoraphilic algorithm
Authors: L. McFetridge, M. Y. Ibrahim
Venue: Robotics and Computer-Integrated Manufacturing (2009)

The Agoraphilic algorithm is an optimistic approach to reactive path planning for mobile robot platforms. The technique uses virtual, attractive forces derived from the surrounding free space. Fuzzy logic is utilised to limit the 'free-space' force so as to promote the movement towards the goal. The algorithm was designed to be a robust technique for reactive navigation that could be implemented without the fuss of tuning the sensitive parameters required for other classical navigation routines. Several simulations plus some preliminary experimental results are presented here to demonstrate the algorithm's potential.
Data dependency in multiple classifier systems
Authors: Rozita A. Dara, Mohamed S. Kamel, Nayer Wanas
Venue: Pattern Recognition (2009)

In this paper, the data dependency of aggregation modules in multiple classifier system is being investigated. We first propose a new categorization scheme, in which combining methods are grouped into data-independent, implicitly data-dependent and explicitly data-dependent. It is argued that data-dependent approaches present the highest potential for improved performance. In this study, we intend to provide a comprehensive investigation of this argument and explore the impact of data dependency on the performance of multiple classifiers. We evaluate this impact based on two criteria, prediction accuracy and stability. In addition, we examine the effect of class imbalance and uneven data distribution on these two criteria. This paper presents the findings of an extensive set of comparative experiments. Based on the findings, it can be concluded that data-dependent aggregation methods are generally more stable and less sensitive to class imbalance. In addition, data-dependent methods exhibited superior or identical generalization ability for most of the data sets.
Healthcare Information Exchange in Regional eHealth Networks Implications for Initiatives in Advancing Shared Care
Authors: Kari Harno, Pirkko Nykänen, Jukka Ohtonen, Antto Seppälä, Kyösti Kopra
Venue: Proceedings of the 2009 International Conference on eHealth, Telemedicine, and Social Medicine (2009)

Healthcare information exchange (HIE) has been refined from point-to-point messaging to wide-area networks integrating multiple service providers. Presently, federated information systems connect more than 25 hospitals with 60 municipal health centres in three Finnish hospital districts. The usability and benefits of these regional eHealth networks (RHIN) were studied in a subset of 10.000 end-users from secondary and primary care in these hospital districts. The usability of several functions was assessed by on-line survey in 72 physicians and the benefits by interviewing 30 health care professionals after subsequent operational use of RHIN in patient care. Although the survey revealed physician dissatisfaction with several key functions of usability, user experiences indicated that 85 % of the doctors and nurses found HIE with RHIN to have a beneficial effect on patient care. This information may be applied when reshaping the human context of shared care and migrating RHIN to upgraded national eHealth network.
Distributed simulation in industry -- a survey, part 3 -- the HLA standard in industry
Authors: Csaba A. Boer, Arie de Bruin, Alexander Verbraeck
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Distributed simulation, more specifically the HLA standard, is hardly applied in industry. We have conducted an extensive survey with COTS (commercial off-the-shelf) simulation package vendors and simulation experts, both from defence and industry, that focuses, amongst others, on the question what the reasons are behind this phenomenon. In this paper we analyze the reactions that we obtained, categorizing them into arguments related to distributed simulation in general, arguments related to HLA and arguments pertaining to the embedding of HLA concepts in COTS packages. These answers will lead us, we believe, to insights that can serve as guidelines to make distributed simulation more attractive for the industrial simulation community.
Two semi-online scheduling problems on two uniform machines
Authors: C. T. Ng, Zhiyi Tan, Yong He, T. C. E. Cheng
Venue: Theoretical Computer Science (2009)

This paper considers two semi-online scheduling problems, one with known optimal value and the other with known total sum, on two uniform machines with a machine speed ratio of s&ge;1. For the first problem, we provide an optimal algorithm for s&isin;[1+&radic;3/2, 1+&radic;21/4], and improved algorithms or/and lower bounds for s&isin;[1+&radic;21/4, &radic;3], over which the optimal algorithm is unknown. As a result, the largest gap between the competitive ratio and the lower bound decreases to 0.02192. For the second problem, we also present algorithms and lower bounds for s&ge;1. The largest gap between the competitive ratio and the lower bound is 0.01762, and the length of the interval over which the optimal algorithm is unknown is 0.47382. Our algorithms and lower bounds for these two problems provide insights into their differences, which are unusual from the viewpoint of the known results on these two semi-online scheduling problems in the literature.
Teach Yourself VISUALLY Adobe Photoshop Lightroom 2
Authors: Lynette Kent
Venue:  (2008)

The amateur and home photographers today take many more photos than they ever would have with film cameras, and the sorting process alone can be an ominous and time consuming chore. Unlike Photoshop, Lightroom enables the photographer to organize, process, and output large numbers of files and effectively streamline the so called digital workflow, reducing the work and enhancing the flow of processing digital photographs. All the features of Lightroom such as moving the cursor directly on the image to adjust it, which are intended to simplify digital editing for the professional photographer, also make the photo editing process easier for the amateur. For once the professional level application is easier to use for everyone. This book provides the general photo enthusiast easy to follow steps to get past the intimidation factor of "a professional tool." Teach Yourself Visually Adobe Photoshop Lightroom will simplify the "photo geek speak," explain the interface and tools so the average person with a digital camera will feel comfortable and be able to start organizing, editing, and outputting photos right away.
Nonnegative Matrix Factorization for Combinatorial Optimization: Spectral Clustering, Graph Matching, and Clique Finding
Authors: Chris Ding, Tao Li, Michael I. Jordan
Venue: Proceedings of the 2008 Eighth IEEE International Conference on Data Mining (2008)

Nonnegative matrix factorization (NMF) is a versatile model for data clustering. In this paper, we propose several NMF inspired algorithms to solve different data mining problems. They include (1) multi-way normalized cut spectral clustering, (2) graph matching of both undirected and directed graphs, and (3) maximal clique finding on both graphs and bipartite graphs. Key features of these algorithms are (a) they are extremely simple to implement; and (b) they are provably convergent. We conduct experiments to demonstrate the effectiveness of these new algorithms. We also derive a new spectral bound for the size of maximal edge bicliques as a byproduct of our approach.
Web search and information credibility analysis: bridging the gap between Web1.0 and Web2.0
Authors: Katsumi Tanaka
Venue: Proceedings of the 3rd International Conference on Ubiquitous Information Management and Communication (2009)

As computers and computer networks become more common, a huge amount of information, such as that found in Web contents including multimedia content (images, videos etc.), has been accumulated and circulated. Such information gives people a framework for organizing their private and professional lives. However, in general, the quality control of Web content is insufficient due to low publishing barriers. In result there is lot of mistaken and unreliable information on the Web that can have detrimental effects on users. This calls for technology that would facilitate judging the trustworthiness of content and the accuracy of the information that users encounter on the Web. Such technology should be able to handle a wide range of tasks: extracting credible information related to a given topic, organizing this information, detecting its provenance, clarifying background, facts, and other related opinions and the distribution of them, and so on. Also, as for Web search, conventional Web search engines still suffer from their low precision/recall ratio especially for searching multimedia contents (images, videos etc.). In this paper, we propose an idea to enhance conventional Web search and to analyze Web information credibility by bridging the gap between Web 1.0 contents and Web 2.0 contents. Based on the idea, we overview our research activities on Web search and their information credibility.

Authors: Joshua D. Jackson, Dale W. Callahan, Jon R. Marstrander, Jim A. Richardson, Ihsan K. Hakima
Venue: Proceedings of the 8th conference on Signal processing, computational geometry and artificial vision (2008)

The majority of vehicle tracking solutions are designed for general navigation, and as a result have low positional accuracy requirements. Projects requiring above average accuracy quickly run into high costs, while projects requiring sub-meter accuracy are limited by cost and availability. This paper presents a novel low-cost approach for using off-the-shelf components to provide relative-tracking precise to ±5 cm over a limited spatial domain.

Authors: Mahmoud Z. Iskandarani
Venue: Proceedings of the 12th WSEAS international conference on Computers (2008)

The design, build and characterization of a reprogrammable neural switch (RNS) are carried out. The function of such a switch is to operate as a synaptic processor behaving in an adaptive manner and suitable to be used as a compact programmable device with other artificial neural network hardware. Interaction between constituent materials forming the switch is discussed and carrier interaction during Programming cycles is explained. Modeling of the switch is carried out using a simple semiconducting circuit, which is accompanied by mathematically description, thus assisting in the process of characterization. Programmability of the switch is proved to be bi-directional and reversible with hysterisis effect which is due to excess charge storage.

Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

Minicomputers are quite useful for the acquisition and reduction of data from physical and biomedical research equipment. Minicomputers have become progressively less expensive and are now comparatively easily available for research investigators. At that point, the problem arises to interface minicomputers effectively to research equipment. This interfacing task became recently somewhat facilitated by specialized books and articles. Quite recently minicomputers were utilized for multiple ion detection in combined gas chromatography---mass spectrometry. A computer centered instrument for simultaneous measurements of absorption and fluorescence was also described quite recently. Finally, a computer system for the acquisition and analysis of temperature jump data was described. Although a Biomation 802 transient recorder was used as fast analog-to-digital converter by the latter authors, they utilized a Digital Equipment Corporation PDP 11/20-8k and a teletypewriter ASR-33 as equipment connected to the output of the Biomation 802. In this paper we will describe the use of a Digital Equipment Corporation PDP 8/e-8k minicomputer as active processor between the Biomation 802 and a Hazeltine 2000 CRT terminal, which is also connected to a Hazeltine dual tape cassette.

Venue: Integrated Circuit and System Design. Power and Timing Modeling, Optimization and Simulation: 18th International Workshop, PATMOS 2008, Lisbon, Portugal, September 10-12, 2008. Revised Selected Papers (2009)

Considering the digital switching noise viewpoint, in this paper we illustrate a methodology to compare different logic synthesis techniques by applying a stochastic analysis to switching currents. The technique consists in three main steps. First, we synthesize the Boolean function into two logic expressions (classical SOP form and the three-level 2-SPP form). Then, we simulate the corresponding circuits at transistor level to obtain the switching currents. Finally, we post-process the obtained currents to obtain their amplitude density functions and power spectral densities.
A linguistic comparison of MUMPS and COBOL
Authors: Thomas Munnecke
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

There are endless discussions in data processing circles about which computer language is best. Not surprisingly, the arguments generally boil down to each participant saying: "The language I know is best." These dogmatic beliefs often lead to vigorous debates among programmers who use different languages.
Real time extraction of related terms by bi-directional lexico-syntactic patterns from the web
Authors: Hiroaki Ohshima, Katsumi Tanaka
Venue: Proceedings of the 3rd International Conference on Ubiquitous Information Management and Communication (2009)

We propose a method for detecting related terms of a given term quickly using a conventional Web search engine. There are many kinds of related terms. For example, hypernyms and hyponyms are basic related terms that are treated in dictionaries. Synonyms and coordinate terms are also well defined related terms. Topic terms and description terms represent topics of the given term and they are vaguely defined. There are other related terms such as abbreviations and nicknames. The proposed method can be used these many kinds of related terms. It extracts related terms from text resources only from Web search results, which consist of titles, snippets, and URLs of Web pages. We use two different kind of lexico-syntactic patterns to extract related terms from the search results, and they are called bi-directional lexico-syntactic patterns. The proposed method can be applied to both languages where words are separated by a space such as English and Korean and ones where words are not separated by a space such as Japanese and Chinese. The proposed method does not need any advanced natural language processing such as morphological analysis or syntactic parsing. It works relatively fast with good precision.
