Salavatipour, Mohammad, Pirwani, Imran
Technical report TR09-06. We consider the problem of partitioning the set of vertices of a given unit disk graph (UDG) into a minimum number of cliques. The problem is NP-hard and various constant factor approximations are known, with the current best ratio of 3. Our main result is a polynomial...

Technical report TR03-11. Biological systems for spatial navigation provide fine-tuned mechanisms for orientation and complex navigational behavior. Experimentation in human beings is aimed to discover perceptual cues utilized to perform navigation in Virtual Reality environments. Such...

A Robust CBIR Approach Using Local Color Histograms
2001
Technical report TR01-13. Global color histograms are well-known as a simple and often way to perform color-based image retrieval. However, it lacks spatial information about the image colors. The use of a grid of cells superimposed on the images and the use of loca l color histograms for each...

A Stable Algorithm for Multi-dimensional Padé Systems and the Inversion of Generalized Sylvester Matrices
Download1994
Jones, Anthony, Cabay, Stan, Labahn, George
Technical report TR94-07. For k+1 power series a0(z), ..., ak(z), we present a new iterative, look-ahead algorithm for numerically computing Pade'-Hermite systems and simultaneous Pade' systems along a diagonal of the associated Pade' tables. The algorithm computes the systems at all those...

A Study of Image Indexing Techniques for Multimedia Database Systems
1995
Niu, Youping, Ozsu, M. Tamer, Li, Xiaobo
Technical report TR95-19. The role of indexing in query optimization is well-understood in the database community. Indexes enable efficient access to a subset of a database. There have been many studies on indexing within the context of relational database management systems (RDBMS). The most...

Marsland, Tony, Gao, Yaoqing, Lau, Francis
Technical report TR95-23. Multiple threads can be used not only as a mechanism for tolerating unpredictable communication latency but also for facilitating dynamic scheduling and load balancing. Multithreaded systems are well suited to highly irregular and dynamic applications, such as tree...

We present a distribution-based and transformation-based approach to synthetic data generation and demonstrate that the approach is very efficient in generating different types of multi-dimensional numerical datasets for data clustering and outlier analysis. We developed a data generating system...

Technical report TR97-04. Genetic algorithms (GAs) are probabilistic search algorithms that are loosely based on biological evolution. Analyzing genetic algorithms has proven difficult, for a variety of reasons, but a landscape paradigm that rigorously models the search of GAs has become...

Technical report TR94-10. In recent years, numerous new backtracking algorithms have been proposed. The algorithms are usually evaluated by empirical testing. This method, however, has its limitations. Our thesis adopts a different, purely theoretical approach, which is based on...

Technical report TR06-07. The development of the Ignorant Value Assessment Tool (DIVAT) for two-player Limit Texas Hold'em is discussed in detail. The tool is then applied to several poker matches to obtain a statistically unbiased reduced-variance analysis of skill differences. Please note:...
