Complexity-Reduced Iterative MAP Receiver with Partial Sphere Decoding in Spatial Multiplexing System
– In this paper, a partial sphere decoding approach is proposed to reduce the computational complexity of implementing the iterative MAP receiver for spatial multiplexing system,...

Positive higher-order queries
We investigate a higher-order query language that embeds operators of the positive relational algebra within the simply-typed λ-calculus. Our language allows one to succinctly de...

Reliability-driven layout decompaction for electromigration failure avoidance in complex mixed-signal IC designs
The negative effect of electromigration on signal and power line lifetime and functional reliability is an increasingly important problem for the physical design of integrated cir...

Query Rewriting for Semistructured Data
We address the problem of query rewriting for TSL, a language for querying semistructured data. We develop and present an algorithm that, given a semistructured query q and a set ...

Plan Selection Based on Query Clustering
Query optimization is a computationally intensive process, especially for complex queries. We present here a tool, called PLASTIC, that can be used by query optimizers to amortize...
