An improved hybrid method is discussed, employing a finite-element method along with Faraday's law and standard circuit analysis, in order to predict the induced voltages and currents on a pipeline with defects on its coating, running parallel to a faulted line and remote earth. Such defects are a frequent situation especially when old pipelines are considered and are modeled as resistances, called leakage resistances. The fault is assumed to be outside the parallel exposure so that conductive interference is negligible and therefore the problem is a two-dimensional one. Input data are power line and pipeline configuration, physical characteristics of conductors and pipeline, fault and power system terminal parameters and location and value of leakage resistances. Simulation results show that for small values of leakage resistances, defects act as a mitigation method for the induced voltages on the pipeline. However, in that case large currents that flow to earth through the defects can damage the pipeline.

作者： E.-S. El-Alfy Yu-Dong Yao H. Heffes Wireless Systems Engineering Laboratory (WISELAB) Department of Electrical and Computer Engineering Stevens Institute of Technology Hoboken NJ USA

In the next generation cellular mobile multimedia networks, a resource allocation policy, which prioritizes handoff requests over new calls while making efficient use of the network resources, will be an essential component for successful operation. In this paper we develop a new handoff prioritized scheme which adapts the allocation policy according to the current traffic conditions. The goal is to minimize the new call blocking while keeping the handoff failures close to a targeted objective. This problem is formulated as a constrained semi-Markov decision process (SMDP) with average cost criterion. A simulation-based learning algorithm is developed to determine a control policy from direct interaction with the network without a priori knowledge of the network dynamics or traffic. Extensive simulations test the effectiveness of the algorithm under a variety of traffic conditions. Comparisons with other resource allocation policies, such as complete sharing and channel reservation, are presented.

A design strategy for a rail-to-rail input/output operational amplifier in standard CMOS 0.18 /spl mu/m digital process with a 0.5-V threshold is presented. It uses a novel level shifting technique of the input signal and a dynamically biased class AB output stage based on a switched-capacitor configuration. The amplifier is capable of working with a power supply as low as 1-V while providing a 26.6 MHz unity gain frequency and a 67 degree phase margin with a load condition of 5 pF and 20 k/spl Omega/. The overall circuit dissipates 400 /spl mu/W.

This work gives an analytical performance measure of the common packet channel (CPCH) in 3rd Generation Partnership Project (3GPP) wideband code division multiple access (W-CDMA) systems. The CPCH procedure of the channel assignment (CA) mode is modeled as an Erlang loss network, and a technique for analyzing Erlang loss networks is applied to get the expression of the system throughput and delay. The theoretical results are verified with computer simulations.

This paper studies the performance of negative acknowledgement- (NAK-) based ARQ which is a conventional selective repeat ARQ except sending an acknowledgment message only when a transmission error occurs. A Markovian error channel model is considered for both forward and feedback channels. The throughput and mean extra delay in terms of RTD (round trip delay) are obtained. The result shows that the throughput of NAK-based ARQ in a noisy feedback environment is as good as that of a selective repeat ARQ scheme with a perfect feedback channel.

Two architectures for a 1-V, 10-bit 200-kS/s successive approximation analog-to-digital converter (ADC) implemented in a standard CMOS 0.18 μm digital process are presented. A track-and-hold circuit based on a novel implementation of the bootstrapped low-voltage analog CMOS switch with a novel rail-to-rail track-and-latch comparator circuit is described. A pMOS-only ladder containing a rail-to-rail current-to-voltage converter, performs the DAC function in the second ADC topology whereas a conventional R-2R ladder is used in the first one. Successive approximation and control logic is implemented using of robust single clock phase D flip flop. © 2001 IEEE.

Though the areas of secure multicast group architecture, key distribution and sender authentication are under scrutiny, one topic that has not been explored is how to integrate these with multilevel security. Multilevel security is the ability to distinguish subjects according to classification levels, which determines to what degree they can access confidential objects. In the case of groups, this means that some members can exchange messages at a higher sensitivity level than others. The Bell-La Padula model outlines the rules of these multilevel accesses (see Bell, D. and La Padula, L., MITRE Report, M74-244, MTR 2547 v2, 1973). In multicast groups that employ multilevel security, some of these rules are not desirable, so a modified set of rules is developed and is termed differential security. Also, this paper proposes three methods to set up a differentially secure multicast group: (1) naive approach, (2) multiple tree differential security (DiffSec) approach, and (3) single DiffSec tree approach. Our simulation studies show that both single and multiple DiffSec tree approaches offer similar performance in terms of bandwidth consumption, which is significantly better than that of the naive approach. We also discuss the suitability of the schemes, taking into account scalability and implementation issues.

Micro-sensors and actuators are differentiated from conventional sensors and actuators by their size, cost, and techniques used in their manufacture. The small size of MEMS is a convenience, a contribution to their potentially low cost, and a source of new conceptual challenges. Improvements in sensing structures, process technology, and circuit technology are presently addressed by the MEMS research community. Unavoidable, the next logical step in-the MEMS evolution will be development of precision micro-systems by integrating a number of smart control functions including self-calibration, self-testing, structural compensation, and even communication with one or more other sensors located on the same chip. The control community will be the critical driving force in these developments. This paper gives an overview of functional blocks needed for Smart MEMS and provides several examples highlighting benefits of the paradigm.

We develop a new software layer called the Automatic parallel Detection Layer (APDL) for the automatic transformation from sequential to parallel code. The main interest, in this research, is the parallelism at loop level, because significant parallelism in programs almost invariably occurs in loops. The proposed APDL has five processes for code transformation: the sequential source code parser, data dependence analysis of this code, partitioning, scheduling both task and data, and generating parallel source code. Many cases have been studied to evaluate the performance of the developed layer. The performance is evaluated depending on the execution time of: the sequential code, the parallel programmer code, and the code output from APDL for the same case study. Performance results show that APDL greatly improves the execution time with respect to sequential execution time, and saves on the high cost of a parallel programmer.
