Technical report TR04-13. Existing random models for the constraint satisfaction problem (CSP) all require an extremely low constraint tightness in order to have non-trivial threshold behaviors and guaranteed hard instances at the threshold. We study the possibility of designing random CSP models...

Maani, Rouzbeh, Kalra, Sanjay, Yang, Yee-Hong
In this paper, we applied texture analysis to evaluate cerebral degeneration in amyotrophic lateral sclerosis (ALS). Two well-known methods, the gray level co-occurrence matrix (GLCM) and the gray level aura matrix (GLAM) were employed to extract texture features from routine T1 and T2 MR images....

Oliveira, Stanley, Zaiane, Osmar
Technical report TR02-13. Discovering hidden patterns from large amounts of data plays an important role in marketing, business, medical analysis, and other applications where these patterns are paramount for strategic decision making. However, recent research has shown that some discovered...

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...

Pu, Calton, Meersman, Robert, Liu, Ling
Technical report TR96-11. We propose a transactional activity model (TAM) for specification and management of open-ended cooperative activities. TAM is a careful combination of an activity composition model with extended transaction models such as split/join transactions. In contrast to each of...

Lower Bounds on the Population Size in Genetic Algorithms and Implicit Parallelism Revisited
Download2002
Technical report TR02-20. Determining an appropriate population size is very important in genetic algorithms and is closely related to the principle of implicit parallelism. In this paper, the problem of sizing the population is formulated as that of minimization of sampling errors. Two sampling...

Technical report TR94-01. Objectbase Management Systems are expected to serve data management needs of a wide range of application domains with possibly different query optimization requirements, creating the need of extensibility in the query optimizer to be able to handle the diversity of those...

Technical report TR04-10. This report overviews the Mass Spectrometry Data Classification and Feature Extraction problem. After reviewing previous research new classification and feature extraction techniques are presented and empirically evaluated on three data sets. One of the key points made...
