(2005)We then consider the problem of fair endtoend resource allocation in wireless networks. First, we consider the problem of allocating resources (time slots, frequency, power, etc.) at a base station to many competing ...

(200903)The SarbanesOxley Act inspired research on longterm highintegrity retention of business records, based on the longterm immutability guarantees that WORM storage servers offer for files. Researchers recently proposed a ...

Efficient Bayesian Network Inference: Genetic Algorithms, Stochastic Local Search, and Abstraction (1999)Two major research results are presented that relate to creating hard synthetic Bayesian networks for empirical research on inference algorithms. One method translates deceptive problems studied in genetic algorithms to a ...

(1992)An independence system consists of a ground set and a collection of subsets of the ground set called independent sets with the property that any subset of an independent set is independent. We study the problem of computing ...

PDF (8MB) 
(1994)Program analysis is critical to many software engineering tools. However, modern programming languages make use of a number of constructs that greatly complicate dataflow analyses, for example, unrestricted pointers, ...

(2007)While the previous two directions reduce integration costs by improving the performance of automatic tools (either by improvements to the tool itself, or by leveraging users to boost tool accuracy), the last direction ...

(1999)Our experiments with all proposed approaches on IBM SP2s, using the Panda parallel I/O library as a testbed, show that our strategies significantly reduce the I/O time required for the checkpoint and snapshot operations ...

PDF (7MB) 
(2008)Given the cost of physically modifying the backbone, as well as the relatively slow speed at which core architectures change compared to higher layers, it is important to be able to optimize the network using soft solutions ...

PDF (2MB) 
(1989)The directmethod circuit simulation technique solves the entire system at every iteration and thus avoids the problem of slow convergence or even nonconvergence, which could occur when relaxationbased techniques are ...

PDF (7MB) 
(1998)We address the issue of transforming multiphase designs, a popular industry practice to equivalent onephase designs to enable the application of the current equivalence checking techniques. We propose an algorithm to ...

PDF (202kB) 
(1997)The increasing amount of instructionlevel parallelism required to fully utilize high issuerate processors forces the compiler to perform increasingly advanced transformations, many of which require adding extra operations ...

PDF (13MB) 
(1993)The use of index structures can increase the performance of query processing. However, the index structures for standard databases are not suitable for the nonstandard database applications such as geographical applications, ...
