RCQ-GA: RDF Chain Query Optimization Using Genetic Algorithms
Lecture Notes in Computer Science, 2009 The application of Semantic Web technologies in an Electronic Commerce environment implies a need for good support tools. Fast query engines are needed for efficient querying of large amounts of data, usually represented using RDF. We focus on optimizing a special class of SPARQL queries, the so-called RDF chain queries.

Rotating combined queueing (RCQ)
Computer Architecture News, 1996 Network service guarantees not only provide significant performance benefits to distributed computing systems (more balanced resource utilization, fast fault recovery, and fair network access), but they are also essential for many new applications requiring real-time communications with continuous data types (audio/video).

The use of the RCQ-D in patients with poly drug abuse [PDF]
Addiction Research & Theory, 2009 Aim: The transtheoretical model is often used in substance abuse treatment planning. For polydrug abusing patients, operationalizing the stages of change is more difficult, as their readiness to change may differ depending on the substances. It was the aim of this study to investigate if the same structure of the Dutch Readiness to Change Questionnaire

As society moves into the age of active knowledge management and sharing, inter-clinician relationships and communities of practice can be directed to support quality improvement efforts within healthcare organizations. It is argued that successful adoption of the processes that are critical to quality improvement is necessary for durable improvements ...

Two different methods of assessing alcohol-dependent clients' motivation for change or recovery on admission to a hospital-based, day-treatment alcohol problems unit were compared in their ability to predict post-treatment abstinence survivorship in a follow-up study.

RCQ-ACS: RDF Chain Query Optimization Using an Ant Colony System
2012 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology, 2012In order to effectively and efficiently disclose the ever-growing amount of widely distributed RDF data to demanding users in real-time environments, RDF query engines need to optimize the join order of partial query results. For this, a two-phase optimization (2PO) algorithm and a genetic algorithm (GA) have already been proposed.

IEEE Transactions on Audio Speech and Language Processing, 2010 The rate-distortion performance of conventional resolution-constrained quantization (RCQ) based on the mean-squared error criterion (MSE-RCQ) is generally compromised by the impact of distortion outliers and source mismatch. Not only the mean distortion,

Valid and constructive thoughts: Continuing the dialog about the RCQ
Communication Reports, 1991This brief essay continues the ongoing controversy over the status of the Role Category Questionnaire as a measure of cognitive complexity. The central thesis advanced is that several theoretical and methodological issues regarding the RCQ are still unanswered and await empirical investigation. The dozens of studies typically cited bv proponents of the
