This paper presents a detailed analysis of the power-supply voltage (IR) drop scaling in DSM technologies. For the first time, the effects of temperature, electromigration and interconnect technology scaling (including resistivity increase of Cu interconnects due to electron surface scattering and finite barrier thickness) are taken into consideration during this analysis. It is shown that the IR-drop effect in the power/ground (P/G) network increases rapidly with technology scaling, and using well-known counter measures such as wire-sizing and decoupling capacitor insertion with resource allocation schemes that are typically used in the present designs may not be sufficient to limit the voltage fluctuations over the power grid for future technologies. It is also shown that such voltage drops on power lines of switching devices in a clock network can introduce significant amount of skew which in turn degrades the signal integrity.

The paradigm of design for biosystem-on-a-chip (BioSoC), is that multidisciplinary skills are required. Thus, the educational goals are to develop an understanding of micro/macro collaboration along with the ability to apply and use multidisciplinary skills for the design and performance evaluation of a "biosystem on a chip". The need for the architectural design of the BioSoC addresses the next-generation of intelligent information processing systems.

作者：张建武刘延庆 School of Mechanical Engineering Shanghai Jiaotong University Shanghai 200030 China School of Mechanical Engineering Shanghai Jiaotong University Shanghai 200030 Chinaasically on the multi-body system dynamics the virtual prototype of the hydraulic shock absorber for the bench test is developed in the ADAMS environment. Dynamic behaviors of the absorber are studied by both computer simulation and real test. Numerical predictions of dynamic responses are produced by the established virtual prototype of the absorber and compared with experimental results. It has been shown from the comparison that the vibration behaviors of the prototype with hysteretic damping characteristics are considered to be more identical with the bench test results than those of the same prototype with piecewise linear damping properties are. The current virtual prototype of the shock absorber is correct and can be a developing terrace for the optimizing design of the absorber and matching capability of the whole car.

Transforming knowledge between connectionist and symbolic machine learning approaches is not a uniform task and there is no general recipe for performing it. Irrespective of the way the transformation of knowledge, the developed methods usually fall into two classes: methods with high rate of transformed knowledge is done, but with a lot of restrictions concerning the type of data in the training sets, training methods, and the size of data sets;and methods with moderate rate of transformed knowledge, but with less restrictions. Our main interest was to find or develop a technique that would possess the knowledge acquisition power of neural networks and explanation power of decision trees. That is why we developed a NN-DT Cascade method, an embedded hybrid of neural networks and decision trees, which is capable of transforming a part of knowledge from the neural network into a decision tree. © 2002 Nanyang Technological University.

Modern medicine generates huge amounts of sensitive data. Data mining and knowledge discovery systems can be used to extract useful information/knowledge in order to to improve future diagnoses and reduce costs. On the other hand, when analysing data, the most recent methods, that extract the most accurate knowledge and decision models, should be used. This can be established with a service enabling quick access to newly developed methods. In this paper, a service for doing this, named IFSIMS (Internet Framework Service for Intelligent Medical systems), is presented.

High dynamic range CMOS image sensor with conditional reset

High dynamic range CMOS image sensor with conditional reset

Custom Integrated Circuits Conference (CICC)

作者： Sung-Hyun Yang Kyoung-Rok Cho Communication Circuit & System Design Laboratory Department of Computer and Communication Engineering Chungbuk National University Cheonghu Chungbuk South Korea

In this paper, we propose a new image pixel structure for high dynamic range operation, which is based on a multiple sampling scheme and conditional reset circuits. To expand the dynamic range of the sensor, the output of the pixel is sampled multiple times in an integration time. In each sampling, the output of the pixel is compared with a reference voltage, and the result of this comparison activates the conditional reset circuit. The times of conditional reset during the integration contribute to the increase of the dynamic range of the sensor. Dynamic range can be increased to N, where N is the sampling times in an integration time. The test chip was fabricated with a 0.65-/spl mu/m CMOS technology (2-P, 2-M).

Searching for new rules and new knowledge in problem areas, where very little or almost none previous knowledge is present, can be a very long and demanding process. In our research we addressed the problem of finding new knowledge in the form of rules in the diabetes database using a combination of decision trees and association rules. The first question we wanted to answer was, if there are significant differences in sets of rules both approaches produce, and how rules, produced by decision trees behave, after being a subject of filtering and reduction, normally used in association rule approaches. In order to accomplish that, we had to make some modifications to both the decision tree approach and association rule approach. From the first results we can conclude, that the sets of rules, built by decision trees are much smaller than the sets created by association rules. We could also establish, that filtering and reduction did not effect the rules derived from decision trees in the same scale as association rules.

A qualification platform for design reuse

The application and development of reusable components (intellectual property, IP) has become a regular part of modern design practices. The IP provider on one side and the IP integrator (user) on the other may be in the same company or separate participants in the microelectronic design market. In both cases, the transfer of IP remains a complex and time-consuming task. The qualification of IP gains a significant relevance for successful application and transfer of IP. This paper proposes an IP qualification methodology for an automated quality check that also incorporates current standards. Through embedding of the new concept into the regular design flow, IP transfer comes closer to an easy mix and match of virtual components. The presented approach has been validated during an industrial case study.

AEven small leakage in submarines can lead to serious consecutive damage, since they operate under high water pressure. Such leakage including damage to piping and the bull eventually result in human casualties and loss of expensive equipment as well as the loss of combat capabilities. In such cases, a decision-making system is necessary to respond immediately to the damage in order to maintain the safety or the survival of the submarine. So it is necessary to have an automatic system that can generate responses and give advice to the operator on bow to make decisions to maintain the survivability of the damaged vessel. In this paper a knowledge-based decision support system for submarine safety is developed. The domain knowledge is acquired from submarine design documents, design expertise, and interviews with operators. The knowledge consists of responses regarding damage of the pressure bull and piping systems. Expert elements are deduced to obtain the decision from the knowledge base, and the system makes recommendations on bow to cope with damage to the bull and piping and whether the submarine should stay in the sea or to surface. It is demonstrated that the developed system is well simulated to the real situation through sample applications.
