In this paper, we develop a new paradigm for access control and authorization management, called task-based authorization controls (TBAC). TBAC models access controls from a task-oriented perspective than the traditional subject-object one. Access mediation now involves authorizations at various points during the completion of tasks in accordance with some application logic. By taking a taskori...

Modern realities in a rapidly changing world are condensing events with conflict potential, which will certainly affect the prospects for further development of mankind as whole, well relation to individual states and social groups. Such phenomena disunity, racial ethnic intolerance, terror, often resulting dramatic interethnic conflicts, actualize need develop institution mediation. In October...

In this work we present our participation in the ImageCLEF 2017 tuberculosis task. The task consists of detecting five tuberculosis (TB) types and predicting drug resistance from lung CT (Computed Tomography) volumes. Our approach is based on a previously developed non-parametric method. Tested on CT images of Chronic Obstructive Pulmonary Disease (COPD) patients, it consists of describing each...

the ph.d. entrance examinations of islamic azad university in iran are administered annually to select the best applicants for ph.d. programs. in consideration of the important decisions, which are made on the basis of the results of these examinations, the present study was conducted to provide a qualitative evaluation of field-specific language subtests (flss) of four entrance examinations ad...

The construction of semi-empirical Hamiltonians for materials that have the predictive power is an urgent task in materials simulation. This task is necessitated by the bottleneck encountered in using density functional theory (DFT)-based molecular dynamics (MD) schemes for the determination of structural properties of materials. Although DFT/MD schemes are expected to have predictive power, th...

The task-switching paradigm offers enormous possibilities to study cognitive control as well as task interference. The current review provides an overview of recent research on both topics. First, we review different experimental approaches to task switching, such as comparing mixed-task blocks with single-task blocks, predictable task-switching and task-cuing paradigms, intermittent instructio...

We consider the task allocation problem in open environments where providers have special interests for some tasks and consumers have some expectations w.r.t. the results they get. We propose Libra, a mediation mechanism that adapts online to the consumer and providers’ expectations. We implemented Libra and compared it to two important baseline methods for allocating tasks, namely Capacity bas...

We introduce in this paper correspondence patterns as templates to model ontology alignments. Correspondence patterns capture regularities recurring when aligning ontologies. They come in complement of ontology matching algorithms and graphical mapping tools, and facilitate the task of the engineer building the alignment between a pair of ontologies. We develop an ontology mediation framework b...
