The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...

Background The use of a medical simulator should enhance the goals of minimally invasive surgery: patient safety, cosmesis, shortening the length of hospital admissions, and reducing cost. Using an innovative approach to the handling of ultrasound images in virtual reality simulation, this article describes a process that employs a hybrid model of deformable models that can be applied in the te...

In this paper, a low cost, wearable six Degree of Freedom (6-DOF) hand pose tracking system is proposed for Virtual Reality applications. It is designed for use with an integrated hand exoskeleton system for kinesthetic haptic feedback. The tracking system consists of an Infrared (IR) based optical tracker with low cost mono-camera and inertial and magnetic measurement unit. Image processing is...

Virtual Enterprise (VE) brings not only opportunities but also more uncertainties and risks for the enterprises. To deal with the uncertainty of the cost for risk control in virtual enterprise, this paper focuses on the method of VE multi-strategies multi-selections risk programming problem considering robustness. The risk programming model to minimize the global risk level with the constraint ...

Aiming at large-scale job scheduling, allocating resource dynamically in order to reduce cost is a significant problem in cloud. In this paper, we study the resource allocation at the application level, instead of studying to map the physical resources to virtual resources for better resource utilization in cloud computing environment. We propose a multi-dimensional resource allocation scheme f...

Realistic simulation and manipulation of virtual cloth based on energy minimization techniques require higher computations. A model realizing force as well as shape to manipulate the virtual cloth demands even more computational cost. Mesh resolution of cloth has a great effect on the computational cost of cloth simulation. Therefore, granularity of mesh must be chosen in a manner that represen...

The laboratory component of undergraduate engineering education poses challenges in resource constrained engineering faculties. The cost, time, space and physical presence requirements of the traditional (real) laboratory approach are the contributory factors. These resource constraints may mitigate the acquisition of meaningful laboratory experiences by students, which is especially true in de...

Despite the fact that large scale shared-memory multiprocessors have been commercially available for several years, system software that fully utilizes all of their features is still not available. These machines require system software that is scalable, supports fault containment, and provides scalable resource management. Software supporting these features is currently unavailable, mostly due...
