— Concerning algebraic grammars in reduced form, bisimulation in the graph ofleft dérivations is known to be décidable. The quotient of the above graph by ils greatest bisimulation, called the canonical graph, is indeed isomorphic to the graph ofleft dérivations for another algebraic grammar in reduced form, produced by an effective procedure.

One very effective method for managing large data sets is aggregation or binning. In this paper we consider two aggregation methods that are tightly coupled with interactive manipulation and the visual representation of the data. Through this integration we hope to provide effective support for the aggregation process, specifically by enabling: 1) automatic aggregation, 2) continuous change and...

This article reports on the results of a national survey of AAMFT Approved Supervisors. The respondents (N .= 550) answered questions regarding areas of concentration during supervision, specific techniques employed, professional goals and priorities, and theoretical models used in supervision. Results are compared with a previous survey conducted in 1976 (Everett, 1980). Although audiotapes of...

Only limited attempts have been made in the financial or outsourcing streams of academic writings to explore or quantitatively model the relationship(s) between operational and financial performance metrics of outsourced service providers. Since humanitarian supply chains (which are formed in response to human or environmental disasters) rely on an outsourcing model it is critical that there is...

Characters are vital to large video game worlds as they bring a sense of life to the world. However, background characters are known to rarely exhibit any sign of motivated behavior or emotional state. We want to change this by assigning these characters emotions that can be identified through their non-verbal behavior. We feel the addition of emotion will allow players to feel more connected t...

The pattern-based sequence classification system (PBSC) identifies regularly occurring patterns in collections of sequences and uses these patterns to predict meta-information. This automated system has been proven useful in identifying patterns in written language and musical notations. To illustrate the wide applicability of this approach, we classify symbolic representations of speech-accomp...

Semantic hierarchy construction aims to build structures of concepts linked by hypernym–hyponym (“is-a”) relations. A major challenge for this task is the automatic discovery of such relations. This paper proposes a novel and effective method for the construction of semantic hierarchies based on word embeddings, which can be used to measure the semantic relationship between words. We identify w...

In this work we present a novel approach to ensemble learning for regression models, by combining the ensemble generation technique of random subspace method with the ensemble integration methods of Stacked Regression and Dynamic Selection. We show that for simple regression methods such as global linear regression and nearest neighbours, this is a more effective method than the popular ensembl...

The indentation slope curve from a spherical indentation on elastic-plastic materials is examined. By comparing it with that of an linear elastic material of the same elastic properties, we found that the start point of plastic yielding for an elastic-plastic material can be easily located from the indentation slope curve. Based on this analysis, a simple but effective method is proposed tomeas...

This paper introduces a new algorithm for approximate mining of frequent patterns from streams of transactions using a limited amount of memory. The proposed algorithm consists in the computation of frequent itemsets in recent data and an effective method for inferring the global support of previously infrequent itemsets. Both upper and lower bounds on the support of each pattern found are retu...
