Purpose – Over the past 50 years India has been experiencing rapid population growth, causing the migration of a large part of the population to the cities looking for livelihood. This resulted in massive increments of population in the cities that has led to the increase of pollution. Gujarat, being a highly industrialized state, is a case in point. The systems for treatment and water disposal of this state are highly challenged. The northwestern state of Gujarat has no effective systems for treatment or disposal of waste water. The purpose of this article is to address this problem, introducing a geographic information system (GIS) approach to record the characterization, analyze the needs and generate a conceptual GIS database in the state. Design/methodology/approach – This paper outlines the background, suggested methodology for the development of a GIS database pollution dependent control of water pollution in the state of Gujarat in India. The present research is to install a document management system that has been developed in providing organizing chart, sorting, querying and retrieving of key data. A computerized laboratory information system on monitoring of quality of ambient air has been developed. Findings – An integrated GIS database has been generated involving creation of pollutant contours, querying and visualizing the query output in spatial and nonspatial form. Originality/value – The authors have created a complete geospatial database for the environmental monitoring for the whole state of Gujarat. They have dealt with nearly 36,000 different files from different sources and put them together to create the database. A computerized laboratory information system on monitoring of quality of ambient air has been developed. Frontend application programs have been developed in Visual Basic and the backend database to integrate the laboratory data and the existing data in oracle database. © 2005, Emerald Group Publishing Limited

VLSI Test Symposium

TARO test patterns are transition fault test patterns that sensitize each transition fault to all of the outputs that can be reached from the fault location. We were not able to identify any ATPG tool that can generate TARO test patterns directly. This paper describes a technique to use an existing transition fault ATPG tool to efficiently generate TARO test patterns. This technique was used to generate TARO patterns for the ELF35 test chip. When these patterns were applied to the ELF35 chips, all of the defective chips were discovered (no test escapes).

In this paper, we propose new convolutive source separation and selective null beamforming methods using a pilot-based channel estimation technique in reverberation environments. First, we show convolutive sound source separation methods in determined and overdetermined cases. For the acoustic channel estimation, we propose a new channel estimation method using pilot sequence conceptually similar to a pilot code in wireless communication. Pilot sequence is composed of sum of sinusoidal sequences at frequencies matching STFT (Short-Time Fourier Transform) frequencies. Proposed channel estimation method considered the effect of spectral sampling with frequencies matching STFT frequencies provides precise channel information we want to know and has less computational loads than other competitive methods. After acoustic channel estimation, we can separate the signals from observations using inverse(or pseudo-inverse) operator of estimated channel matrix at each frequency bins. We show the proposed method has better performance than other competitive methods in various measures. Second, we propose selective null beamforming using a pilot-based channel technique. If we use same pilot sequence at each transmitter, we can obtain relative difference of acoustic channel between transmitters as well as between microphone array. From estimated channel information, we can calculate beamforming weight vectors to null the signals at target location and to transmit the signals to desired location without distortion using singular value decomposition at each frequency bins. We evaluate the performance of proposed methods through experiments as well as the computer simulations.

High-throughput proteome annotation refers to the activity of extracting information from all proteins in a particular organism using bioinformatics software on a high performance computing platform such as the grid. The Encyclopedia of Life (EOL) project [1] aims to catalog all proteins in all species for public benefits using an Integrative Genome Annotation Pipeline [2] (iGAP). The intrinsic complexity of the pipeline makes iGAP an ideal life sciences application to drive grid software development. It is a flagship application for the TeraGrid project [3]. The deployment of iGAP on the grid using grid middleware and mediator software has been described previously [4]. The heterogeneous and distributed computing environment on the grid requires an interactive user interface where jobs may be submitted and monitored. Here we describe our international collaborative effort in creating a grid portal solution for grid computing in life sciences under the auspices of PRAGMA [5]. Specifically, the development of GridMonitor for interactive monitor of iGAP workflow, and the use of a GridSpeed [6] generated iGAP application portal are described. The portal solution was part of the EOL demonstration at Supercomputing 2003 (SC'03) [7], where resources from 6 institutions on 5 continents are utilized to annotate more than 36,000 proteins from various species. It is a testimony to the necessity and expediency for international collaboration in an increasingly global grid computational environment to advance life sciences research. © Springer-Verlag Berlin Heidelberg 2005.

In today's fast paced economy product design is becoming increasingly complex and requires tighter integration of the engineering and business processes not only within the individual businesses, but also across enterprises. This high demand for real-time business-to-business collaboration across enterprises requires a robust and secure channel not only for data exchange but also for process interaction. This paper presents a robust and secure collaborative environment to enable engineers to perform complex design analysis such as CAD, CAE, PDM, optimization, cost modeling, etc. across the network and Business firewalls. However, maintaining the secure communication protocol and close monitoring of the distributed computing process across network can present itself as a significant challenge. A multi-level security approach is developed to prevent any potential security and/or communication failure. This paper presents a typical engineering design scenario between General Electric (GE) and one of its vendors. In particular it will demonstrate how this environment can facilitate the communication of both data and applications across enterprise boundaries to tightly integrate a vendor into the GE's Design for Six Sigma process.

Five state colleges and universities in the University of Georgia System are collaborating to develop an online B.S. IT degree, slated to open for enrollment in Fall 2004. The participating institutions range in size and mission from large regional universities to regional colleges. The process of jointly designing a degree to be offered either wholly or substantially online for a non-traditional audience has produced several noteworthy intermediate outcomes. The first peripheral but important outcome is the benefit of collaborative self-study, which has already affected participating programs. Second, online BSIT planning has informed the definition of state-level course requirements for Associate degree level concentrations in Information Technology. In terms of the program itself, intermediate outcomes include a curriculum developed by consensus in reference to emerging accreditation guidelines, closely examined program and course prerequisites, and a process for jointly planning, reviewing and certifying courses. This paper first describes the project's context, background and the needs assessment, then briefly describes the technological and administrative infrastructure required to deliver the degree collaboratively and at a distance. We focus on the program's impact to this point, curricular structure and rationale, and conclude with our expectations for the project's future. Copyright 2003 ACM.

The complexity of both parallel architectures and parallel applications poses several problems for the development of performance analysis and optimization tools. In this paper, we describe the motivations and the main aspects of the design of the Dynamic Probe Class Library (DPCL), an object based C++ class library that provides an infrastructure to reduce the cost of writing instrumentation for performance tools. Additionally, we present some of the performance tools built on top of DPCL, which demonstrate the power and flexibility of the library. © 2001 IEEE.

Image segmentation is a mixture of complex sub-problems. Following the concept of perceptual organization, we first discuss categorization of these problems. Then we propose a method to bind most of all pixels in each image regions. It is based on image region scanning dynamic wave propagation and region label information represented in the probability distribution. This wave propagation method realizes boundary noise robustness as well as its interpolation. The segment representation in probability distribution enhances the stability of the segmentation result.

The influence of electrostatic truncation on simulations of polarizable systems

引用

AIP Conference Proceedings 1999年第1期492卷 114-126页

作者： Steven W. Rick Advanced Biomedical Computing Center SAIC-Frederick NCI-Frederick Cancer Research and Development Center Frederick Maryland 27102

Different schemes for the treatment of long-ranged electrostatic interactions will be examined for water simulations using the polarizable fluctuating charge potential. Several different methods are compared, including Ewald sums, potential shifting, spherical truncation and reaction field corrections. For liquid water, properties such as the energy, pressure, dynamics and structure are more sensitive to the treatment of the long-ranged interactions with polarizable than with non-polarizable potentials.
