Bakalárska práca sa zaoberá problematikou klient-server aplikácií a technológiami používanými na softvérovú implementáciu klient-server aplikácií v programovacom jazyku java. Cieľom bakalárskej práce je paralelizácia genetického algoritmu pre problém batohu a vytvorenie dvoch distribuovaných modelov pre technológie CORBA a Hessian. V teoretickej časti práce sú popísané základné pojmy týkajúce sa sieťovej komunikácie, vysvetlenie klient-server modelu sieťovej komunikácie, sú rozobraté technológie java rmi, CORBA a Hessian. V práci je popísaný paralelný a distribuovaný model spracovania dát, genetický algoritmus a jeho využitie na vyriešenie problému naplnenia batohu. V praktickej časti je vytvorený paralelný a distribuovaný model genetického algoritmu pre problém naplnenia batohu s použitím technológií CORBA a Hessian. V práci je spravené porovnanie týchto modelov z hľadiska času výpočtu. Výsledky merania času genetického algoritmu sú v tabuľkách.

The author developed an rmi (referred to here as xrmi) that includes a code generation function for object serialization and confirmed its effectiveness. The distinguishing characteristics of xrmi are that it combines run-time code generation for object serialization and migration of generated code while maintaining the ease of use of the java rmi. This enables the. time required for the second and subsequent client-side serializations to be reduced and high-speed deserialization to be done at the server side by migrating the code for deserialization, which is generated at the client side, to the server side. As a result, xrmi runs faster than standard java rmi and a significant performance improvement can be expected for network applications. This paper presents the background for the research and describes the basic design and implementation of xrmi, as well as experiments for confirming xrmi performance. (C) 2003 Wiley Periodicals, Inc.

This paper introduces the constitute, structure and the software model of a set of networked manufacturing process monitoring system, using java network technique to realize a set of three layer distributed manufacturing process monitoring system which is comprised with remote manage center, manufacturing process supervision center and the units of measure and control layer such as displacement sensor, the device of temperature measure and alarm etc. The network integration of the production management layer, the process control layer and the hard ware control layer is realized via using this approach. The design using object-oriented technique based on java can easily transport to different operation systems with high performance of the expansibility.
