A computer model is developed for a system consisting of an electronic chopper circuit driving a magnetic actuator, which in turn operates a hydraulic valve that controls a hydraulic cylinder. Here the entire system is modeled using SPICE, a widely used electric circuit simulation program. Besides the SPICE model of the chopper circuit, included are a model of the magnetic actuator obtained by electromagnetic finite element analysis and a model of the hydraulic valve and cylinder based on their hydraulic and mechanical equations. The complete model is used to compute typical system performance. Copyright © 2002 SAE International and NFPA.

Mid-depth Text Understanding by Abductive Chains for Topic Sentence Selection

International Journal of computer Processing of Languages 2002年第3期15卷 341-357页

This paper introduces a mid-depth text understanding methodology. By mid-depth we mean that the methodology is: (1) based on shallow text understanding, (2) accomplished with currently available linguistic instruments, and (3) focused towards understanding texts as deeply as possible. To realize the methodology, we set up two new linguistic devices for sentence extraction — sentence abstraction and abductive chains. Sentence abstraction is processing for sentence revision with concept abstraction. Abductive chains are lexical chains with abduction. The chain consists of abductive links which connect coherent parts of abstracted sentences. It aims to identify the causal propensity described or implied in the text as well as to delineate its recurring concepts. With this methodology, a preliminary attempt at mid-depth text understanding is made to locate the topic sentences of a given text. We expect that this methodology will lead us to develop another practical text summarization system.

Given a test set for stuck-at faults, a primary input value may be changed to the opposite logic value without losing fault coverage. One can regard such a value as a don't-care (X). The don't care values can be filled appropriately to achieve test compaction, test data compression, or power reduction during testing. However, these uses are better served if the don't cares can be placed in desired/specific bit positions of the test patterns. In this paper, we present a method for maximally fixing Xs on specific bits of given test vectors. Experimental results on ISCAS benchmark circuits show how the proposed method can increase the number of Xs on specific bits compared with an earlier proposed method.

In ad hoc networks, each node utilizes its limited resources to carry out the collective operation of the network. It is not always in the best interests of the network's nodes to demand the continuous participation of all nodes in the network operations. We propose an energy dependent participation (EDP) scheme, where a node periodically re-evaluates its participation in the network based on the residual energy in its battery. More importantly, a node gives special consideration to supporting the communication needs of its active network applications and preventing further network partitioning. EDP's localized partition checking algorithm is particularly well suited for the zone routing protocol, where the link-state information is proactively maintained within each node's local zone and routes to faraway nodes are reactively obtained via global queries. Through simulations, we evaluate the impact of our proposed scheme on battery life and network connectivity. Our results suggest that the EDP scheme can increase the usable lifetime of a battery-constraint ad hoc network by over 50%.

Conservation Laws, Uncertainty Relations, and Quantum Limits of Measurements

引用

Physical Review Letters 2002年第5期88卷 050402-050402页

The uncertainty relation between the noise operator and the conserved quantity leads to a bound on the accuracy of general measurements. The bound extends the assertion by Wigner, Araki, and Yanase that conservation laws limit the accuracy of “repeatable,” or “nondisturbing,” measurements to general measurements, and improves the one previously obtained by Yanase for spin measurements. The bound represents an obstacle to making a small quantum computer.

Computational web portals are designed to simplify access to diverse sets of high performance computing resources, typically through an interface to computational Grid tools. An important shortcoming of these portals is their lack of interoperable and reusable services. This paper presents an overview of research efforts undertaken by our group to build interoperating portal services around a Web Services model. We present a comprehensive view of an interoperable portal architecture, beginning with core portal services that can be used to build Application Web Services, which in turn may be aggregated and managed through portlet containers. © 2002 IEEE.
