Multimedia data transmission is becoming a popular application in computer communications. Compared with digital media such as audio or text, real-time video is the most difficult medium for a communication system to handle. The difficulties lie, in part, in the strict end-to-end delay requirements of this medium. It is desirable to maintain a specified quality during a video session. To guaran...

After a successful evaluation at the IMC in the project MIRROR to enhance reflective learning by coaching and usage of two apps developed in the project, the instructional design was further developed. Below three phases are described that show the development from a research prototype to a commercial blended learning course. The first phase was a summative evaluation. Ten staff members took pa...

Economic activities and investments require resources and capital. Developing countries are faced with limited resource; thereforeو the need to select proper projects is intensified. Our country is not an exception to this rule, where lack of adequate resource allocation and planning has caused many projects to come to a standstill. This paper reports on the implementation of an expert system, ...

This paper examines the impact of managers’ social capital on managerial performance. Two dimensions of social capital are compared—the structural embeddedness (i.e., configuration) of a manager’s network of work relations and the relational embeddedness (i.e., quality) of those relations. Based on a sample of 120 product and sales managers in a Fortune 100 pharmaceutical firm, this paper prese...

In this paper we propose an ontology-based dynamic enterprise model to facilitate managerial control. Management control systems serve to implement enterprise strategies, and formal management control systems typically include strategic planning, budgeting, performance measurement, and performance evaluation processes (Anthony and Govindarajan 2004). We focus on the portion of the process where...

An efficient way to manage the workload on High Performance Computing Clusters is to use Resource Managers. One such of the resource manager and job scheduling system for Linux clusters is the Simple Linux Utility for Resource Management (SLURM). At National Energy Research Scientific Computing Center (NERSC), users regularly submit and run hundreds of jobs. Thus, it is necessary to have an acc...

We presents major extension of the widely used TORQUE Resource Manager. Unlike common resource managers that use queuing approach, our solution uses planning (job schedule construction) and schedule optimization in order to achieve better predictability, performance and fairness with respect to common queue-based approaches. Moreover, additional important features are supported, e.g., so called...

This paper presents a GridIMF framework that provides support for adaptive grid services in response to the change of resource supplies and demands in a dynamic computing environment. The framework features a 3-tier hierarchical resource management structure. At the top is a global information manager that serves as a service broker between resource requesters and providers. Resource providers ...

z Abstract AQUA is an integrated resource management architecture for an end-system that can deliver desired QOS to multimedia applications. The proposed architecture (called AQUA for Adaptive End-system Quality of Service Architecture) includes a common framework for managing resources such as CPU, network interface, memory, and bus bandwidth. Contributions of AQUA include an adaptation framew...

data envelopment analysis (dea) is a non-parametric method for assessing relative efficiency of decision-making units (dmus). every single decision-maker with the use of inputs produces outputs. these decision-making units will be defined by the production possibility set. resource allocation to dmus is one of the concerns of managers since managers can employ the results of this process to all...
