SHALLOW LEVEL RECOMBINATION CURRENT DOMINANCE IN TRANSISTOR BETAS
IEEE ELECTRON DEVICE LETTERS
收藏 引用
IEEE ELECTRON DEVICE LETTERS 1993年 第2期14卷 49-50页
作者: LANYON, HPD Department of Electrical and Computer Engineering Worcester Polytechnic Institute Worcester MA USA
A new recombination mechanism, via the high density of shallow donor and acceptors present in the base-emitter junction of integrated circuit transistors, is suggested. In contrast to the recombination via deep center... 详细信息

A finite-element time-domain method using prism elements for microwave cavities
收藏 引用
IEEE TRANSACTIONS ON ELECTROMAGNETIC COMPATIBILITY 1995年 第4期37卷 519-527页
作者: Sacks, ZS Lee, JF Department of Electrical and Computer Engineering Worcester Polytechnic Institute Worcester MA USA
A finite-element time-domain (FETD) method for solving Maxwell's equations was developed by combining prism-based edge elements with central differencing in the time domain. This method solves for the electric fie... 详细信息

ANALYTICAL EXPRESSIONS FOR THE TIME-DOMAIN DISPLACEMENT RESPONSE OF A PIEZOELECTRIC PLATE RESONATOR
收藏 引用
IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL 1995年 第4期42卷 801-803页
作者: USTUNDAG, A LUDWIG, R LEVIN, P Computational Electromagnetics and Ultrasonics Group Department of Electrical and Computer Engineering Worcester Polytechnic Institute Worcester MA USA
An analytical one-dimensional series solution for the time-domain displacement response of a piezoelectric plate is derived. Rather than the usual charge driven electric boundary value formulation, this paper develops... 详细信息

A COMPARATIVE-STUDY OF NONPARAMETRIC SPECTRAL ESTIMATORS FOR APPLICATION IN MACHINE VIBRATION ANALYSIS
收藏 引用
MECHANICAL SYSTEMS AND SIGNAL PROCESSING 1992年 第6期6卷 551-574页
作者: NAJAFI, B HAKIM, H Electrical and Computer Engineering Department Worcester Polytechnic Institute Worcester MA 01609 U.S.A.
The vibration of a machine carries important information about the health of its internal components; this information, if properly extracted, can be extremely useful in the detection of developing faults within the m...

INTEGRATION OF STEREO VISION AND OPTICAL-FLOW BY USING AN ENERGY-MINIMIZATION APPROACH
收藏 引用
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION 1989年 第6期6卷 900-907页
作者: NASRABADI, NM CLIFFORD, SP LIU, Y []Computer Vision Research Group Department of Electrical Engineering Worcester Polytechnic Institute Worcester Massachusetts 01609
A cooperative method is proposed in which image intensity (brightness) and optical-flow information are integrated into a single stereo technique by modeling the input data as coupled Markov random fields (MRF’s). Th... 详细信息

Important considerations in the evaluation of absorbing boundary conditions
收藏 引用
ELECTROMAGNETICS 1996年 第4期16卷 417-433页
作者: Lee, R Chen, Z Jevtic, JO Lee, JF [a] Department of Electrical Engineering ElectroScience Laboratory The Ohio State University Columbus OH USA [b] Department of Electrical and Computer Engineering Worcester Polytechnic Institute Worcester MA USA
In this paper, we study the interaction of an absorbing boundary condition (ABC) with the discretization error. In many cases the major source of error is due to the discretization error and how it couples to the ABC.... 详细信息
