This paper describes the configuration of a cost-efficient monolithic render server aimed at multi-screen Virtual Reality display devices. The system uses common OfThe-Shelf (OTS) PC components and feeds up to 6 independent screens via 3 graphics pipes with the potential to feed up to 12 screens. The internal graphics accelerators each use at least 8 PCIe lanes which results in sufficient bandw...

Java bytecode subroutines are used to compile the Java source language try-finally construct into a succinct combination of special-purpose instructions. However, the space saved by using subroutines, in comparison to simpler compilation strategies, comes at a substantial cost to the complexity of the bytecode verifier and other parts of the Java Virtual Machine. This paper examines the trade-o...

Cloud computing is a trending technology to provide ease of access to services that a user requires with pay-as-you-go model. The number of user requests on the servers increase tremendously therefore increasing load on the servers. This requires a proper load balancing technique to balance the load on the virtual machines. In this paper we have modified an existing algorithm Optimal Cost Sched...

In this paper we establish a general framework for estimating the energy consumption of an embedded Java virtual machine (JVM). We have designed a number of experiments to find the constant overhead of the Virtual Machine and establish an energy consumption cost for individual Java Opcodes. The results show that there is a basic constant overhead for every Java program, and that a subset of Jav...

As low cost commercial video game sensors emerge, realistic full body interactions available in the household can also be utilized to support low cost dismounted Soldier training applications. These sensors, such as the Microsoft Kinect, are designed to work with users directly facing them. However, in an environment designed to train a team, larger spaces are necessary along with the freedom t...

With the availability of the Internet, virtual communities are proliferating at an unprecedented rate. Indepth understanding of virtual community dynamics can help us to address critical organizational and information systems issues such as communities-of-practice, virtual collaboration, and knowledge management. The biggest challenge in fostering a virtual community is the supply of knowledge ...

Java bytecode subroutines are used to compile the Java source language try-finally construct into a succinct combination of special-purpose instructions. However, the space saved by using subroutines, in comparison to simpler compilation strategies, comes at a substantial cost to the complexity of the bytecode veriier and other parts of the Java Virtual Machine. This paper examines the trade-oo...

Virtual machines raise the abstraction level of the execution environment at the cost of restricting the set of supported languages. Moreover, the ability of a language implementation to integrate with other languages hosted on the same virtual machine typically constrains the features of the language. In this paper, we present a highly flexible yet efficient approach to hosting multiple progra...

One possible alternative to standard in vivo exposure may be virtual reality exposure. Virtual reality integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer-generated virtual environment. Virtual reality exposure (VRE) is potentially an efficient and cost-effective treatment of anxiety disorders. VR...

Virtual environments and online games are becoming a major market force. At the same time, the virtual property contained in these environments is being traded for real money and thus attains a real value. Although the legal issues involved with this virtual property have not yet been decided, they will have to be soon. It is foreseeable that the next generation of very large virtual worlds wil...
