Manufactured VLSI chips are prone to defects. These chips must be thoroughly tetsted prior to shipment to customers. In this talk a brief introduction to the issues involved in test of large VLSI designs is given. A method we developed recently to reduce the cost of test application will also be presented.

People have been inventing new ideas in computer systems for nearly four decades, usually driven by Moore's law. Many of them have been spectacularly successful: virtual memory, packet networks, objects, relational databases, and graphical user interfaces are a few examples. Other promising ideas have not worked out: capabilities, formal methods, distributed computing, and persistent objects. And the fate of some is still in doubt: parallel computing, RISC, and software reuse. The most important invention of the last decade, the World Wide Web, was not made by computer systems researchers. In the light of all this experience, I will talk about the topics that I think will be exciting to work on in the next few years.

Automated biometrics systems can be modeled as generic pattern recognition systems to study their accuracy performance. Manufacturers as well as researchers of biometrics systems quantify the error performance in terms of Receiver Operating Characteristics (ROC) curves. We argue that confidence intervals or margins of error should be reported for the ROCs to determine whether accuracy differences between systems are statistically significant. We introduce a novel bootstrap technique for computing the confidence regions of the error estimates and compare them to a commonly used parametric method. The proposed technique is inspired by moving block bootstrap which samples data with replacement from blocks of data to account for dependence among the data. We will present results from regular bootstrap and the proposed subset bootstrap to argue that subset bootstrap can provide a better estimate of the confidence interval in biometrics system performance measures.

Pawan Kumar Gupta had graduated B.Tech. from IIT Delhi. After passing out established and managed a chemical unit for nearly 10 years before quitting in search for meaning in life. Took to Vipassanna seriously and along with my wife Anuradha decided to do study the co-relations between Vipassanna and Jungian psychology. Started SIDH an organization working exclusively in the area of education in 1998. Besides running schools catering to various age groups of students SIDH also has a research publication wing. Involved in producing more relevant teaching /learning material to bridge the gap between school & home, school & society. Edit a journal "Raiber" - a serious journal in Hindi critiquing modern "development", "education","modern science" and trying to final viable solutions to the problems India is facing. Write regularly for "Jansetta" (India Exp Group) and other journals. Have edited a book containing articles written over the past 40 years by Dharampal called "Re-discovery India" and "Bharat Ki Panchan". Since 2001 involved in understanding "Madhyastha Darshan" profounded by A. Nagraj and trying to incorporate the understanding in school education.

Currently, visualization of complex biological and physico-chemical systems offers qualitative, heuristic insights or quantitative yet empirical information via statistical summaries. Visualization methods to extract quantitative information and knowledge about the various processes, phenomena and behaviors in the system would be valuable, but currently do not exist. We report on such a methodology developed based on thermodynamic principles and image analysis. A common characteristic of such systems, comprised of multiple phases separated by distinct boundaries or interfaces, is their complex spatial structure. The interfacial areas between the phases, aij, (where i and j can be pairs of phases i and j) provide more accurate metrics for morphology, tortuosity, heterogeneity and anisotropy of such systems, which can be used to improve the analysis and prediction of several phenomena (e.g. flow, signal transfer and communication, energy transfer, reaction coupled with transport, diffusion, heat, mass and momentum transfer) and behaviors (e. g. self-organization, growth, division, atrophy, malignancy), which are strong, direct functions of surface energetics and hence interfacial areas (aij). Algorithms can be developed, using images or graphics as input, for the calculation of phase interfacial areas, saturations and several quantitative indices, metrics and summaries based on the interfacial areas, which represent valuable information about the complexity of the systems, as well as the various physico-chemical, biological or abstract phenomena and behaviors. Such metrics are not empirical, but phenomenologically rooted; hence, they can be directly incorporated into the computational processes simulating the various phenomena and behaviors in complex systems, thus providing effective, quantitative bridges between visualization and computation. Recent work on the use of these metrics for the analysis of several phenomena, such as diffusion, dissolution, bacterial transport, wettability, flow and transport in porous materials demonstrates significant improvement in their prediction. Using microbial, metallurgic and sub-surface systems, we demonstrate how the proposed algorithms can enhance visualization to serve as an integral part of computation and data (knowledge) discovery.

This presentation is a high-level introduction to Tecplot, a scientific visualization software with extensive 2- and 3-D capabilities for visualizing technical data from analyses, simulations and experiments. Tecplot combines general engineering plotting with high-end 3-D scientific data visualization, used in a variety of industries including aerospace, automotive, energy, semiconductor, environmental, and education.면 Tecplot is used by engineers and scientists who need to create a wide range of high-quality plots from simple XY plots to sophisticated 3-D plots from data sets of up to millions of data points. Many Tecplot users are post-processing data created by finite-difference and finite-element numerical simulations of physical processes like fluid dynamics, geophysics, structural dynamics, and electromagnetics. It basically transforms massive amounts of data into a variety of XY, 2-D and 3-D plots. It can load and plot data organized in a variety of grid structures that are used in computer programs to simulate physics (like fluid dynamics, electromagnetics, and heat transfer). Data points can be arranged in multiple blocks of rectangular and body-fitted curvilinear grids, unstructured finite-element grids made of triangles, quadrilaterals, prisms, and bricks. Tecplot can also interpolate random or irregular data into grid structures and even triangulate the data points.
