this paper presents a method for modeling robot and human resources in the context of assembly systems planning. In assembly systems, several redundant resources can be used to increase system flexibility. However, the "quality" of a sequence planning strongly depends on the "quality" of the system modeling. Furthermore, occurrence of unexpected events or variations in availability of resources may have significant impact on the actual planning. Instead of using simplistic models such as available or unavailable resources, the method presented in this paper proposes a more detailed modeling of resource abilities. Products and resources are considered on the same levels and matched together on a final step. the aim of this modeling is to permit analyses and to increase system flexibility.
Systems of systems typically contain many technical systems but also span across and affect different legal and economic entities (e.g., companies, public bodies, etc.). the economic entities are involved in exchanges...

Automatic recovery of 3d pose of multiple interacting subjects from unconstrained monocular image sequence is a challenging and largely unaddressed problem. We observe, however, that by tacking the interactions explicitly into account, treating individual subjects as mutual "context" for one another, performance on this challenging problem can be improved. Building on this observation, in this paper we develop an approach that first jointly estimates 2d poses of people using multiperson extension of the pictorial structures model and then lifts them to 3d. We illustrate effectiveness of our method on a new dataset of dancing couples and challenging videos from dance competitions.
Today advancements in information technology have led to multi-user information systems of high complexity, where users can group, collaborate and share resources. the variety of such systems include a wide range of a...

the Role-Based Access Control (RBAC) model, under which the users are assigned to certain roles while the roles are associated with prescribed permissions, remains one of the most popular authorization control mechanisms. Workflow is a business flow composed of several related tasks. these tasks are interrelated and context-dependent during their execution. Execution context can introduce uncertainty in authorization decisions for tasks. this paper investigates the role-based authorization model withthe context constraints and dynamic cardinality constraints. the Petri-net is used to model the authorization process and the formal expression of the model is presented. the general stochastic Petri-net simplifying method is used to analyze and calculate the authorization workload of a role in the system. Withthis work, given the workflow load, context and role authorization system parameters, we can predict the performance of the constraints role-based authorization system on mobile devices. Based on these performance metrics, the mobile system parameters can be adjusted to achieve the optimal system performance and meet the user demand best.
