Keywords: Systems with time delays Distributed delay Exponential stability Perturbations a b s t r a c t We consider preservation of exponential stability for a system of linear equations with a distributed delay under the addition of new terms and a delay perturbation. As particular cases, the system includes models with concentrated delays and systems of integrodifferential equations. Our met...

Keywords: Continuous time difference systems Exponential stability Lyapunov–Krasovskii functionals a b s t r a c t This paper provides further Lyapunov results for the exponential stability of linear continuous time difference system involving discrete and distributed delays. We consider such a class of systems in the case when the discrete and distributed delays are independent thus completing...

Wireless sensor network is collection of sensor nodes. These nodes can communicate by transferring data to neighbor node. Nodes also have some resources those are limited. In this paper we discuss the different clustering algorithms for efficient utilization of resources. Also discuss the quality parameters of nodes. And gives the proposed solution method “Distributed Weighted Clustering Algori...

one of the ubiquitous routines in medical practice is searching through voluminous piles of clinical documents. In this paper we introduce a distributed system to search and exchange clinical documents. Clinical documents are distributed peer-to-peer. Relevant information is found in multiple iterations of cross-searches between the clinical text and its domain encyclopedia. Keywords—Clinical d...

We propose a fast silent self-stabilizing building a k-independent dominating set, named FID. The convergence of protocol FID, is established for any computation under the unfair distributed scheduler. FID reaches a terminal (also legitimate) configuration in at most 4n+k rounds, where n is the network size. FID requires (k + 1)log(n+ 1) bits per node. keywords distributed computing, fault tole...

This paper presents a dynamic adaptation scheme for the frequency of inter-deme migration in distributed genetic algorithms (GA), and its VLSI hardware design. Distributed GA, or multi-deme-based GA, uses multiple populations which evolve concurrently. The purpose of dynamic adaptation is to improve convergence performance so as to obtain better solutions. Through simulation experiments, we pro...

This paper will present the initial findings of a research into distributed computer rendering. The goal of the research is to create a distributed computer system capable of rendering a 3D model into an MPEG-4 stream. This paper outlines the initial design, software architecture and hardware setup for the system. Distributed computing means designing and implementing programs that run on two o...

A test suite for a key interface within a dimensional measuring system (coordinate measuring machine or CMM) is presented. The test suite consists of test procedures, test definitions, and various testing utilities. A real-time, distributed test utilizing the test suite has been performed and is described. Keywords— conformance test, coordinate measuring machine, distributed testing, interface ...

With an aim of ultra-low power operation, membranetype distributed-feedback (DFB) lasers consisting of wirelike active regions are realized with an InP-based high index-contrast waveguide by using benzocyclobutene (BCB) as well as direct boding on a silicon-on-insulator (SOI) substrate. Lateral current injection (LCI) type lasers on a semi-insulating (SI) InP substrate are also presented. Keywo...

Towards a data-centric workflow approach, we introduce an artifact model to capture data and workflow management activities in distributed settings. The model is built on Active XML, i.e., XML trees including Web service calls. We argue that the model captures the essential features of business artifacts as described informally in [1] or discussed in [2]. To illustrate, we briefly consider the ...
