XACML Policies for Exclusive Resource Usage

The extensible access control markup language (XACML) is the standard access control policy specification language of the World Wide Web. XACML does not provide exclusive accesses to globally resources. We do so by enhancing the policy execution framework with locks.

An Algebra for Composing Ontologies

Ontologies are used as a means of expressing agreements to a vocabulary shared by a community in a coherent and consistent manner. As it happens in the Internet, ontologies are created by community members in a decentralized manner, requiring that they be merged before being used by the community. We develop an algabra to do so in the Resource Discription Framework (RDF). To provide formal sema...

Securing Workflows with XACML, RDF and BPEL

The XACML is the access controller of the World Wide Web (WWW). The current reference implementation has a single policy decision point and a policy enforcement point. If XACML policies are used to control workflow among cooperating web services, such as those envisioned in more contemporary languages like (BPEL), it requires coordination to be policy compliant. We propose the necessary enhance...

Probabilistic approach for biorhythmic analysis to prevent aviation accidents

This paper presents a new methodology, based on the probabilistic approach, for biorhythmic analysis to prevent aviation accidents. The methodology has been developed using the Gaussian distribution technique for reliability evaluation of the aviation system, keeping in mind the biorhythmic effects of the pilot. The normal distributed data of the US Air Force were tested and analysed based on t...
