The valve modulates the oil flow from a free-wheeling mode to braking-and-storing energy, to full braking, to recovering energy and accelerating a load. The valve design achieves this by combining the operating characteristics of the sliding and the rotary operation. The key goals of the present analysis are to demonstrate that the four-position operation is attainable, and to evaluate the valve stability during the transient and the steady state modes of operation and compare it with the stability of the conventional stepped-spool valves. The normal, freewheeling position of the valve is determined by locating its spool in between the two springs of unequal stiffness, thus making it “unbalanced”. The solid model of the proposed design is presented and analysed here.","PeriodicalId":22356,"journal":{"name":"Tenth International Conference on Computer Modeling and Simulation (uksim 2008)","volume":"46 1","pages":"58-63"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75024086","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}

Recently, researchers have tested computational tools to model these systems in order to elucidate the organizational principles. In this paper we recommend using Holonic Multiagent systems for biological networks simulation. Holonical systems guarantee to provide a recursive and hierarchical modeling for complex systems with dynamic and runtime reorganization. They are adopted for simulation where systems have a hierarchical structure and can be decomposed into individual cooperating entities.","PeriodicalId":22356,"journal":{"name":"Tenth International Conference on Computer Modeling and Simulation (uksim 2008)","volume":"43 1","pages":"617-622"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77654018","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}

Research was performed in an effort to improve health service, in particular to reduce average waiting times as well as their variability. Discrete-event simulation modeling provided valuable input into new facility design decisions and showed the efficacy of pooling sources of variation, particularly patient demand and service times. Initial performance of the redesigned facilities was positive; however, dynamic feedback within the system of service centers eventually resulted in unanticipated performance problems. System dynamics models were developed to help predict these implementation problems and suggest some ways to improve results.","PeriodicalId":22356,"journal":{"name":"Tenth International Conference on Computer Modeling and Simulation (uksim 2008)","volume":"39 1","pages":"649-654"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79178622","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}

Computer modelling techniques can be used to simulate motion of the gun during the firing cycle. A three dimensional finite element model of a large calibre gun was developed using ANSYS commercial software and its motion during the firing cycle was simulated to study and predict the effects of various design factors on the dynamic response of the gun. Physical contact conditions of the gun system components have been modelled using contact technology in ANSYS. Results are compared with general responses of the gun system obtained through available docummented sources. Effectiveness of the software for accurate modelling of gun dynamics is discussed.","PeriodicalId":22356,"journal":{"name":"Tenth International Conference on Computer Modeling and Simulation (uksim 2008)","volume":"96 1","pages":"18-22"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80332373","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}

These oscillators are forced by cyclic inputs representing basically the diurnal cycles corresponding to the periodical changes of light and dark phases and adapt their own natural circadian rhythm to them. This adaptation is referred to as entrainment and the oscillators considered for this circadian rhythm entrainment are based on Van der Pol and Lorenz type models. The Van der Pol type oscillator is proposed in a matrix form and subsequently compared with a generalized Lorenz model. The proposed oscillators are linked to a delayed Volterra model and the generic structure is applied to the case of cyanobacteria population growth. Using data recently obtained from the measurements on a laboratory-scale photobioreactor the parameters of oscillators are tuned to fit measured excited growth responses of cyanobacteria concentration.","PeriodicalId":22356,"journal":{"name":"Tenth International Conference on Computer Modeling and Simulation (uksim 2008)","volume":"22 1","pages":"175-179"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82583800","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}
