IEEE International Test Conference

作者： B. Deng W. Glauert Institute for Computer Aided Circuit Design University of Erlangen Nuremberg Erlangen Germany

This work proposes an approach to the formal description of test specifications and automatic test equipment (ATE) architectures for mixed-signal test. For this purpose, two sets of standard components are defined. A test specification and an ATE can then be described using these components and their properties. In the end, they can be represented by several mathematical matrices. Such a description, because of its clarity, is suitable for analysis using mathematical methods and, therefore, forms a basis for the automatic generation of an optimal test concept, which is now a particularly weak spot for the test program and device interface board development.

The most common pharmacophore building concepts based on either 3D structure of the target or ligand information are discussed together with the application of such models as queries for 3D database search. An overview of the key techniques available on the market is given and differences with respect to algorithms used and performance obtained are highlighted. Pharmacophore modelling and 3D database search are shown to be successful tools for enriching screening experiments aimed at the discovery of novel bio-active compounds. © 2004 Elsevier Ltd.

This course provides an introduction to acting and drawing techniques used to develop stronger character animation. Physical warm ups, trust and improvisation will be introduced. Participants will physically participate in theater games and drawing methods. The exercises will inspire an instinctive understanding of staging principles, thumbnail drawing, animal personification, mime, emotional recall and audience awareness. Participants will view demonstrations of acting and drawing by lecturers. Each participant will be provided with theater props, animation paper and pencils for exercises. Animation, from Siggraph's Animation and Electronic Theater, will spotlight excellent acting in animation examples during the course.

Vehicle occupants that are out-of-position can be deadly injured by the deployment of the air bag in a crash situation. In recent years many different sensors and systems have been proposed to detect the type of occupant and the position of the occupant's head. This work presents a method for classification and occupant's head detection based on passive stereo vision. The proposed system uses depth surface analysis and scene statistics together with support vector machines for classification and selection of head candidates. Evaluation of the method shows 99% correct for classification and 98% correct for head detection, using large sets of image data, and image sequences recorded in a driving vehicle.

Modern high-speed optical transmission systems rely heavily on forward error control (FEC) codes to provide quasi error-free transmission over optical channels. The ITU recommendations G.709 and G.975 that underly current optical systems prescribe the use of an FEC code of length 32640 that consists of 16 interleaved 8-error correcting [255,239] Reed-Solomon (RS) codes with 8-bit symbols. The objective is to replace this standard FEC code by a powerful RS code. An obvious candidate is a single 85-error correcting [2720,2550] RS code of length 32 640 with 12-bit symbols, that is shown to have superior random and burst error correction capabilities and to achieve a 2 dB gain relative to the standard FEC code. To implement such a code, a general high-speed parallelized and pipelined encoder and decoder (codec) architecture is developed. It is then shown that the [2720,2550] RS encoder and decoder can be realized in 0.18 /spl mu/m CMOS technology at 1.8 V for a 43 Gb/s optical transmission system with 475 k gates and 1.6 M gates, respectively. The proposed [2720,2550] RS code thus proves to be a good candidate to replace the standard FEC code.

This paper present a silicon microchips designed for rapid, simultaneous testing of samples for DNA amplification by polymerase chain reaction-PCR. Over the last years a lot of researches have been focused in the field of miniaturized reaction and separation systems, including the construction of fully integrated 'lab-on-chip' systems. Microreactors, which initially targeted DNA based reactions such as the polymerase chain reaction, are now used in several other chemical and biochemical assays. We have analysed the temperature uniformity and distribution on the PCR-chip, the temperature distribution of DNA sample, and the transient temperature difference between the heater and DNA sample.

Very Long Instruction Word (VLIW) architectures exploit instruction level parallelism (ILP) with the help of the compiler to achieve higher instruction throughput with minimal hardware. However, control and data dependencies between operations limit the available ILP, which not only hinders the scalability of VLIW architectures, but also result in code size expansion. Although speculation and predicated execution mitigate ILP limitations due to control dependencies to a certain extent, they increase hardware cost and exacerbate code size expansion. Simultaneous multistreaming (SMS) can significantly improve operation throughput by allowing interleaved execution of operations from multiple instruction streams. In this paper we study SMS for VLIW architectures and quantify the benefits associated with it using a case study of the MPEG-2 video decoder. We also propose the notion of virtual resources for VLIW architectures, which decouple architectural resources (resources exposed to the compiler) from the microarchitectural resources, to limit code size expansion. Our results for a VLIW architecture demonstrate that: (1) SMS delivers much higher throughput than that achieved by speculation and predicated execution, (2) the increase in performance due to the addition of speculation and predicated execution support over SMS averages around 12%. The minor increase in performance might not warrant the additional hardware complexity involved, and (3) the notion of virtual resources is very effective in reducing no-operations (NOPs) and consequently reduce code size with little or no impact on performance. © Springer-Verlag Berlin Heidelberg 2003.

The interface and structure of a package of applied programs for the description of plastic deformation by slip in f.c.c. materials are developed. The mathematical model used for calculations is based on the set of differential equations of balance of deformation defects in f.c.c. materials. The processes of generation and annihilation of deformation defects have essentially different rates, and the system of ODE (ordinary differential equations) is stiff. Application of implicit absolutely steady methods is necessary in this situation, because classical Runge-Kutta's methods can require much time for calculations. In this case the use of implicit multistep Gear's method of the variable order for decision the system of ODE is more effective. The applied programs for the description of plastic deformation are oriented for the users who have different qualification in programming and are not require an experience of decision of ODE. © 2003 7th Korea-Russia Intl Sym on Science.
