Many implicit differential equations (IDEs) modelling practical problems can be partitioned into loosely coupled subsystems. In this paper the objective of the partitioning is to permit the numerical integration of one time step to be performed as the solution of a sequence of small subproblems. This reduces the computational complexity compared to solving one large system and permits efficient...

The paper presents the required parameters in the evaluation of the technical state for the High Voltage (HV) circuit breakers. It details some aspects regarding the influence of the kinematics characteristics to the circuit breakers performances. Also, it presents a possibility to use the artificial neural networks (ANN) in the analysis of the circuit breakers kinematics characteristics, in or...

Abstract: The analysis of transversal filters based on a novel cell design in common-source configuration (TF-CS) is presented. Based on this approach, a distributed transversal filter was designed as a monolithic microwave integrated circuit (MMIC) for optical-CDMA receiver systems [1]. In order to assess its performance, a transversal filter based on Gilbert cells (TF-GC) was designed using t...

The purpose of this paper is to present a methodology for the evaluation of the Defect Level in an IC design environment. The methodology is based on the extension of Williams-Brown formula to non equiprobable faults, which are collected from the IC layout, using the information on a typical IC process line defect statistics. The concept of weighted fault coverage is introduced, and the Defect ...

Formal Synthesis is a methodology developed at Kent for combining circuit design and veriication. We have reinterpreted this methodology in Isabelle's theory of higher-order logic so that circuits are synthesized using higher-order resolution. Our interpretation sim-pliies and extends Formal Synthesis both conceptually and in implementation. It also supports integration of this development styl...

Present-day photonic terahertz (100 GHz–10 THz) systems offer dynamic ranges beyond 100 dB and frequency coverage 4 THz. They yet predominantly employ free-space Terahertz propagation, lacking integration depth miniaturisation capabilities without sacrificing their extreme coverage. In this work, we present a high resistivity silicon-on-insulator-based multimodal waveguide topology including ac...

Until now only cursory descriptions of mathematical models for defect sensitivities of integrated circuit chips have been given in the yield literature. This paper treats the fundamentals of the defect models that have been used successfully at IBM for a period of more thanjifteen years. The effects of very small defects are discussedjirst. The case of photolithographic defects, which are of th...
