The reusability of available multimedia and middleware services brings new challenges for enabling flexible and efficient development and deployment of distributed end-to-end multimedia applications with specific ...

In terms of application size---when an application involves one-to-many group communication, we explore resource sharing, both in network bandwidth and computational resources, by proposing a special type of multicasting ...

We present a new method for simplifying simplicial complexes of any type embedded in Euclidean spaces of any dimension. At the heart of this system is a novel generalization of the quadric error metric used in surface ...

Surface remeshing is a fundamental problem in computer graphics, and can be found in most digital geometry processing systems. The majority of work in this area has focused on remeshing with triangle elements, yet quadrilateral ...

Understanding people's commonsense knowledge about physical world is a fundamental problem in building intelligent systems. If this knowledge can be represented and used by computers, they can duplicate people's ability ...

With the emergence of ad hoc networking technology came efforts to provide necessary security support for ad hoc networks. However, due to challenging characteristics of ad hoc environments, providing the same level of ...

Despite advances in intrusion detection and prevention systems, attacks on networked computer systems continue to succeed. Intrusion tolerance and forensic analysis are required to adequately detect and defend against ...

The thesis also proposes Software RISC, a technique for organizing and optimizing component-based systems. The advantages of Software RISC are demonstrated using the flexibility and performance of Quarterware .

Finally, we propose a new class of symmetric updates for use in a quasi-Newton method for nonlinear programming. We show how these updates model the underlying nonlinear equation better than the standard symmetric updates ...
