A trail-based model is proposed to support deadlock-free routing in any networks with node degree no less than four. Basically, given a graph G representing an interconnection network, a walk in G is a finite sequence of edges. The trail-based model generalizes the trip-based model proposed earlier and it eliminates the need for virtual channels. Fundamentals of this model, including the necessary and sufficient condition of constructing a special trail for deadlock-free routing are investigated. The potential of this model is illustrated by applying it to meshes and hypercubes.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129251546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The critical steps in this process include path planning, drilling, and part placement or insertion. To enhance production speed it is important that an optimal (or near-optimal) assembly sequence can be found which performs these tasks in a minimal time. The general PCB assembly problem is at least as complex as the traveling salesperson problem (TSP) which is known to be NP-complete, so that an exact solution using optimization theory is out of the question for any but the smallest problems. Thus a heuristic line of attack must be used, which finds a near-optimal solution in an acceptable time. The present paper concentrates mainly on three such methods: Genetic Algorithms (GA), Evolutionary Programming (EP), and Simulated Annealing (SA). A critical discussion of each technique is given and their performance on realistic PCB assembly problems is analyzed.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123833496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is based on finite element approximation from which the auto-regressive (AR) parametric representation of the beam is obtained. This representation is used to estimate the structural parameters, viz., mass, stiffness and damping coefficient of the beam. The finite dimensional model is then used to design a state-space controller based on the linear quadratic regulator (LQR) principle. The on-line structural parameter estimation and the controller are then combined using the certainty equivalence principle to obtain a linear quadratic self-tuning controller for vibration suppression in cantilever beams. Experimental results on the control of vibration in an aluminium cantilever beam using piezoelectric sensors/actuators are presented.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129699899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have some kind of magic which bestows success on them. Failure, stagnation or growth are their inevitable destinies in proportion to the strength of the magic. As companies grow and merge, management and employees alike desperately hope that the magic will transfer as they take on new form. In most cases however, this magic, this elemental competitiveness dims and eventually disappears leaving only the brute force of headcount and capital in its wake. The author discusses why this is so. He discusses the nature of management and leadership together with the information requirements of managers and leaders.

It has been used successfully in many fields such as image processing, data compression and signal processing. Due to the fact that a wavelet can be chosen from a flexible class of analysis functions with different time-frequency localization properties, its performance surpasses that of the Fourier transform when dealing with transient, or time localized signals. It also has some applications in communication systems. The authors discuss the possibility of using wavelet functions in a digital communication system.

The objective is to travel the furthest distance in one hour on a limited charge, supplied by deep cycle marine type lead-acid battery packs. The rallies, open to any individual, club or educational institution, have been a popular sport in Great Britain and Australia for over a decade and have begun to grow in popularity in the United States. This paper describes how a University of Central Florida student design team is focusing on creating a vehicle capable of extending the current world Electrathon distance record. In addition to aerodynamic and safety concerns, the design focuses on minimizing energy losses in the electrical and drive systems. The completed design serves as the basis for fabrication of a vehicle to be raced in an upcoming Electrathon competition sponsored by the Florida Solar Energy Center.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131235458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
