Hypergeometric series are powerful mathematical tools with many usages. Many mathematical functions, such as trigonometric functions, can be partly or entirely expressed in terms of them. In most cases this allows efficient ...

This thesis proposes a robust method of creating a 3D digital model of an object through stereoscopic reconstruction. There are existing methods and tools for achieving this, but they tend to only perform well under favorable ...

*This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation). The CD requires the following system requirements: Windows MediaPlayer or RealPlayer.

In this paper, we first characterize the fine-grained encounter pattern among mobile users found in a large-scale Bluetooth trace collected by 123 participants at the University of Illinois campus from March to August 2010. ...

3D Tele-immersive systems create real-time multi-stream and multi-view 3D collaborative contents from multiple sites to allow interactive shared activities in virtual environments. Applications of 3DTI include online sports, ...

This thesis describes a module planner for decomposing arbitrary functional specifications of any complexity into abstract cells for custom-VLSI module generation. A graph representing random logic is partitioned and the ...

This dissertation investigates novel methods of accelerating the central computations of physically-based light transport algorithms. We present novel mappings of the crucial primitive operations of ray tracing and shading ...

We evaluate our model on the criteria of expressiveness, performance and usability. The model is sufficiently expressive for applications used in our Active Space. The performance overhead of our access control is demonstrated ...

In evaluating a query using a network database, the links need to either be followed or be saved. Most of the previous approaches follow the links in evaluating a query using a network database. Actually, it is not always ...

In this paper, we propose a new protocol, named DDA (Distributed Delay Allocation), which provides average delay guarantees to real-time multimedia applications in wireless ad hoc networks. By adapting the contention window ...
