Security in provisioning virtual infrastructure services should address two general aspects: supporting secure operation of the provisioning infrastructure, and provisioning a dynamic access control infrastructure as part of the provisioned on-demand virtual infrastructure. The paper refers to the architectural framework for on-demand infrastructure services provisioning and defines the general security requirements to the security infrastructure. Dynamically provisioned access control infrastructure (DACI) reveals a wide spectrum of problems related to the distributed access control, policy and related security context management. Consistent security services design, deployment and operation require continuous security context management during the whole security services lifecycle, which is aligned to the main provisioned services lifecycle. The paper discusses conceptual issues, basic requirements and practical suggestions for provisioning dynamically configured access control services. The paper discusses security mechanisms that are required for consistent DACI operation, in particular use of authorisation tokens for access control and authorisation session context exchange between infrastructure services and providers. The proposed security infrastructure implementation is based on the GAAA-Toolkit that provides rich security session context management functionality with authorisation tickets and tokens. The defined Common Security Services Interface (CSSI) allows uniform call to security services both in the provisioning and virtual infrastructures.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117299630","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}

But in order to override the user's control the vehicle must reason with uncertain information: sensing provides noisy and partial input, vehicle dynamics models are never perfectly calibrated, and other agents (vehicles, pedestrians) may behave unpredictably. In the context of collision imminent braking (CIB), we explore the tradeoffs between risk and interference with normal driving behavior that are inherent in the presence of uncertainty. Specifically, control policies that take a conservative approach to uncertainty are more likely to brake unnecessarily. We compare several control policies on different scenarios using Monte-Carlo hardware-in-the-loop simulations in order to quantify their behavioral characteristics in terms of collision risk and driver interference. We demonstrate that a relatively high degree of safety can be achieved at a relatively low degree of interference, but “idealized” behavior is unattainable in the presence of uncertainty.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134606260","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 involves each appropriate discipline and follows a structured process which guides the team through the early phases of the product life-cycle. Furthermore, integrated design models and domain specific tools support the engineers in generating and exchanging design parameters. As is often misunderstood, Concurrent Engineering is not a design optimization performed by advanced software, but is a team effort where the product development is supported by tools but decisions still made by people. During feasibility studies of space craft design within the “Concurrent Engineering Facility (CEF)” of the German Aerospace Center (DLR) there is a certain set-up of domains each dealing with their respective hard- and software tools. Within the present paper the cases of human-to-human and human-to-machine interaction during the iterative design process is discussed. The focus is set on the interaction between and within the different parties during both the plenary and off-line design sessions. The importance of guided communication and the value of specific and common tool utilization is pointed out. Furthermore, the challenges, constraints, potential improvements and stumbling blocks are identified when dealing with a heterogeneous team of experts in such early design phases.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132610167","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}
