Service Redundancy Strategies in Service-Oriented Architectures
Redundancy can improve the availability of components in service-oriented systems. However, predicting and quantifying the effects of different redundancy strategies can be a comp...

An Analysis of Cardinality Constraints in Redundant Relationships
In this paper, we present a complete analysis of redundant relationships in the entity-relationship model. Existing approaches use the concept of functional dependencies for ident...

Optimization of Complex Nested Queries in Relational Databases
Due to the flexible structures of SQL, no general approach works efficiently for all kinds of queries. Some special kinds of queries can be further optimized for better performa...

Compliant motion tasks for robot manipulators subject to joint velocity constraints
We develop non-smooth motion controllers that enable redundant manipulators to perform surface tasks, that involve force/torque interactions. The robot joint rates are constrained ...

Fast Search Method for Image Vector Quantization Based on Equal-Average Equal-Variance and Partial Sum Concept
The encoding process of image vector quantization (VQ) is very heavy due to it performing a lot of k-dimensional Euclidean distance computations. In order to speed up VQ encoding,...
