Currently, various hardware and software companies are developing augmented reality devices, most prominently Microsoft with its Hololens. Besides gaming, such devices can be used for serious pervasive applications, like interactive mobile simulations to support engineers in the field. Interactive simulations have high demands on resources, which the mobile device alone is unable to satisfy. Th...

Video servers are essential in Video-on-Demand and other multimedia applications. In this paper, we present our high-performance clustered CBR video server, Odyssey. Odyssey is a server connecting PCs with switched Ethernet. It provides efficient support for normal play and interactive browsing functions such as fast-forward and fast-backward. We designed a set of algorithms for scheduling, syn...

We are developing mmGrid (Multimedia Grid) as an extensible middleware architecture supporting multimedia applications in a grid computing environment. Our vision is to provide support for interactive applications from the following domains: graphics, visualization, streaming media and tele-immersion. The initial deployment will be within an enterprise as a mechanism for provisioning computing ...

Hashcash was originally proposed as a mechanism to throttle systematic abuse of un-metered internet resources such as email, and anonymous remailers in May 1997. Five years on, this paper captures in one place the various applications, improvements suggested and related subsequent publications, and describes initial experience from experiments using hashcash. The hashcash CPU cost-function comp...

This paper presents an application of interactive fuzzy goal programming to the nonlinear multi-objective reliability optimization problem considering system reliability and cost of the system as objective functions. As the decision maker always have an intention to produce highly reliable system with minimum cost, therefore, we introduce the interactive method to design a high productivity sys...

The simulation of uid ows around complex geometries starts to be computationally possible. Thus, it has become important to provide the Computational Fluid Dynamics (CFD) community with tools that allow easy manipulation of physical geometry and, for an eecient use of resources , interactive splitting of computational domain. We propose here an object-oriented approach to the deenition of an In...

—Recognizing that privacy rights are complicit in the very forms of economic monitoring and data gathering they ostensibly oppose, this essay offers a critique of corporate surveillance as a technique for exploiting the work of being watched. Consumers who submit to comprehensive surveillance in response to offers of convenience and participation perform valuable work for corporations and marke...

We present an open-source virtual manipulative for conditional log-linear models. This web-based interactive visualization lets the user tune the probabilities of various shapes—which grow and shrink accordingly—by dragging sliders that correspond to feature weights. The visualization displays a regularized training objective; it supports gradient ascent by optionally displaying gradients on th...
