The hose resource provisioning model promises to provide an easy–to–use characterization framework for Virtual Private Network service offerings. Significant research effort has recently been spent on proposing new algorithms for provisioning cost–optimal networks specified according to this new model. However, a detailed comparison of the bandwidth requirement for networks designed based on th...

as spending on it rises steeply, organizations become increasingly technology-dependent and, consequently, they become highly vulnerable to the risks of it failure. the latest report on the failure of many complex it projects to deliver key benefits on time and to target cost and specification was published jointly by the royal academy of engineering and the british computer society. one of the...

A supply chain is a set of suppliers, manufactures and distributors, which are linked together. The first chain is a supplier and the last one is customers. What is the most important in supply chain are highquality products by the least cost and the most benefit. In this regard, each input and output and intermediate have unit price and unit cost information. The cost-minimization and the prof...

Minimally invasive procedures become increasingly popular due to their potential advantages. The correct choice of access to the operation area is essential for a safe and successful surgery. Besides traditional training options (e.g. cadaver-based,) virtual training systems gain importance due to their flexibility and cost efficiency. We developed a novel 3D interaction method to improve the u...

Current touch technology provides precise and accurate large multi-touch surfaces, which allow multiple users to collaborate in these two-dimensional setups. Furthermore, recent developments in the field of display technology support visualization of three-dimensional (3D) virtual environments (VEs) in high-fidelity visual detail on these surfaces. Finally, cost-efficient depth cameras such as ...

Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...

Server virtualization solutions such as VMware Infrastructure are increasingly being deployed because of their effectiveness in addressing current challenges related to the cost and operation of the server environment in the data center. VMware addresses these challenges by running multiple virtual machines on a single physical server, thus increasing utilization and simplifying operations, whi...

This paper presents a novel enhancement in design of virtual keyboards for consumers of tablets and standard computing devices. Hand video is captured for virtual keyboard functionality. Hand video is augmented with a background keyboard and displayed on lower part of screen to provide feedback to user for seamless interaction with virtual keyboard. Hands are detected in video sequence. Finger ...

Efficient allocation of tasks to available resources is a critical problem in cloud computing. Load balancing algorithms are basic approach to optimized resource allocation. This paper presents a static load balancing algorithm to allocate tasks to virtual machines in optimized way. The algorithm is based on a group based allocation strategy. The strategy determines the allocation of virtual ma...

A virtual prototype of a synthetic aperture radar processor is being created by Lockheed Sanders. It includes VHDL models and Ada application code. The virtual prototype is a behavioral and structural model which matches the hardware architecture which was selected as part of this effort. A s part of the RASSP program, we are answering the question: "How can one use VHDL to validate hardware / ...
