This work is an extension of Hinton's work on \"under-specification\". Even though emergence is a universal phenomenon that can hardly be modeled, there are still attempts to understand, propose solution what is known by non-desired emergent properties in industrial systems design. This paper focuses also on under specification and impact of requirement evolution. Some approaches even appear to be infeasible as in natural systems; however industrial systems are designed following various methods and techniques and the interface to user is often poorly specified and developed. In that respect, interfaces between systems and human are very hard to model as emergent behavior is hardly predicted and hence largely unknown. The paper attempts at characterising such properties and initiate the debate on a roadmap for such research to support case studies and applications.","PeriodicalId":123709,"journal":{"name":"2015 Third World Conference on Complex Systems (WCCS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129242732","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}

Thus many studies have been focusing on capitalizing knowledge and practices of systems engineering processes. We proposed in a former work a complete solution (SysPEM: System Process Engineering Metamodel) to this problem starting from the engineering process models to process orchestration and execution control. One of the main components of this solution is a scheduling engine able to reach balance between time consumption and the respective interest of each resource. But, as we implemented our solution in the context of a real-life case study, we noticed its inability to provide high quality schedules when the available resources are severely reduced, this limitation is due to the fact that the scheduling engine is limited to using the available resources given as input as an absolute constraint. In this paper we will provide a solution to this problem through the proposition of additional resources in a cost optimization context. Our work is strongly linked to our former publications, conveniently cited in this paper, as the completion of the original solution and, as we shall see at the end of the paper, shall be considered in the context of the same case study in order to review execution results.","PeriodicalId":123709,"journal":{"name":"2015 Third World Conference on Complex Systems (WCCS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116744696","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}

Medical Image Sharing is a term for the electronic exchange of medical images between hospitals, physicians and patients. Rather than using traditional media, such as a CD or DVD, and either shipping it out or having patients carry it with them, technology now allows sharing of these images using the internet. In this research paper, the proposed approach is to secure medical images stored in the cloud by using Iris recognition as a human biometrics to check identity of the user who has the authorization to access the medical images. Experiments using well know benchmark CASIA-Iris V4 data sets show that the obtained results is more efficient in protecting the data on the cloud compared to the approach presented in [24] by 20%.","PeriodicalId":123709,"journal":{"name":"2015 Third World Conference on Complex Systems (WCCS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117184790","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}

Access control is one of these required security concerns. Several access control models are defined in the literature and this multitude of models creates heterogeneity of access control systems between the collaborating organizations. And this is manifested in the policy definition languages as well as in the enforcement mechanisms. In this paper, we propose a generic model of access control that allows defining each authorization rule in an abstract manner (high level language). These abstract policies can be mapped into low level concrete policies written according to the model adopted by the organization. The abstraction of the access control will involve elements of access control systems that are: models, policies and mechanisms.","PeriodicalId":123709,"journal":{"name":"2015 Third World Conference on Complex Systems (WCCS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124904925","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 toughest challenge of these networks is the energy conservation. So, most of MAC protocols designed for WSNs, aim to reduce energy consumption, which affects negatively the latency, especially if these networks are deployed in emergency response applications. In this paper we present a strategy that respects energy constraint and, in the same time, aims to manage the medium access according to the priority of messages. Our results prove that our algorithm enhances the quality of service (QoS) in terms of prioritized message latency, as well in other performance criteria.","PeriodicalId":123709,"journal":{"name":"2015 Third World Conference on Complex Systems (WCCS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125000046","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}
