The aim of this research was to develop a better tool for conducting safety analyses. Therefore, the goal of the research was to develop a data management tool from the viewpoint of the system safety concept and it was decided to narrow down available methods to the hazard and operability (HAZOP) analysis. This paper will explain the tools and methods which were used in developing the tool and give an overview of the development process. The developed data management tool improves analysis data management, by enabling safety analysts to conduct hazard and operability analysis more easily and to produce reports rapidly. Data is more structured in the database and the platform opens up new possibilities for additional development.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134074014","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}

Prediction of toxic effects of chemical compounds based on experiments involving animals and human beings is very expensive in terms of time, social and financial cost. Therefore it is vital to make use of all available information obtained from experiments and build up a more effective hybrid classification/prediction system to incorporate any available useful piece of knowledge for initial in silico toxicity validation. The paper proposes a correlative data-oriented fusion algorithm to develop effective models based on multi- source data for classification applied to predictive toxicology. Traditionally hybrid intelligent systems integrate just models build on individual data sets by some sort of voting algorithms. We propose an algorithm to generate improved classifiers by use of correlative information of chemical compounds on different endpoints for effective classification.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134081451","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}

Descriptions of engineering objects such as elements and structures of products, results of tests and analyses, and engineering processes for design, analysis, and manufacturing of products have developed into very complex integrated data structures. Application of these complex product models has been extended to support lifecycle management of product data. Engineering utilizes advanced characteristics of modeling software such as analysis of behaviors of modeled objects, adaptive actions for controlled modifications of engineering objects, selection of optimal sets of parameters, etc. The next step of integration is awaited to establish virtual intelligent spaces where all outside and inside effects are reacted by a high level model. The objective is simulation of physical intelligent spaces. The authors conceptualized virtual intelligent space as a well- organized structure of descriptions and behavior definitions for engineering objects that identified in a physical space. Sensor signals in physical intelligent space are replaced by received change information, processing of change information is done by behavior analysis, and actuators are replaced by adaptive action generators. This paper starts with characteristics, of virtual intelligent space. Following this, description of behaviors of modeled objects as essential technique of virtual space is explained. Finally, essential processes in virtual space are outlined.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130286422","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 contains modularized, distributed subsystems in configurable and maintainable software. Starting from the customer order, to planned order dispatch, the ERP main components and the information flow within the system is presented. The software architecture contains the ERP components that are implemented using enterprise Java beans, deployed in a J2EE application server.

We consider symmetric and asymmetric linear coupling. The internal dynamics of each neuron is modeled by the space-clamped Hodgkin-Huxley equations. We start with the symmetric case. Results in the literature show that for strong enough coupling the two neurons show the same behaviour at all times. They may be periodically spiking or at rest. We define these states as perfect synchrony. When decreasing the coupling strength to small positive values almost perfect synchronization is retained. As we move towards negative values of the coupling the two neurons still synchronize but in a different way, they spike periodically with half-period phase shift from each other. As we go towards lower negative values, the system becomes totally unstable. Periodic states where the two neurons synchronize are also defined as 1:1 phase locked modes. The asymmetric coupled system is studied as a perturbation from the symmetric case.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114830659","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}

In a PSO scheme each particle flies through the search space with a velocity that is adjusted dynamically according with its historical behavior. Therefore, the particles have a tendency to fly towards the best search area along the search process. PSO is also an evolutionary computation technique well adapted to the automatic design of electronic devices. In this line of thought, this paper proposes a PSO based algorithm for logic circuit synthesis. The results show the statistical characteristics of this algorithm with respect to number of generations required to achieve the solutions. The results are compared with other two evolutionary algorithms (EAs), namely genetic and memetic algorithms (GA and MA).","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133813669","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}
