Regardless of the knowledge structure lack about Resource Description Framework (RDF) data, difficulties, principally, occur in specifying and answering queries. Approximate querying is the solution to find relevant information by getting a set of sub structures (e.g. sub graphs) matching the query. Approaches based on the structure and others based on semantic, marginalized the common meaning ...

This paper presents a new analytic method that can be used for analyzing perceptual relevance of unit selection costs and/or their sub-components as well as for tuning of unit selection weights. The proposed method is leveraged to investigate the behavior of a unit selection based system. The outcome is applied in a simple experiment with the aim to improve speech output quality of the system b...

In this paper we present the application of a recently proposed, general, algorithm for combinatorial optimization to the unbalanced minimum common string partition problem. The algorithm, which is labelled Construct, Merge, Solve & Adapt, works on subinstances of the tackled problem instances. At each iteration, the incumbent sub-instance is modified by adding solution components found in prob...

We propose a sub-structural niching method that fully exploits the problem decomposition capability of linkagelearning methods such as the estimation distribution algorithms and concentrate on maintaining diversity at the sub-structural level. The proposed method consists of three key components: (1) Problem decomposition and sub-structure identification, (2) sub-structure fitness estimation, a...

This paper evaluates the effects of the use of Product Lifecycle Management and its three sub-systems Organizational Memory, Project and Resource Management and Cooperative Work systems on three components of knowledge integration in New Product Development: knowledge transfer, translation and transformation. A second aim of this paper is to explicate and discuss the use of the crisp set versio...

Plackett-Burman design was used for selection of important media components such as carbon and nitrogen sources and minerals which affect poly(hydroxybutyrate) production and cell growth of Methylobacterium extorquens DSMZ 1340. Among the studied variables, nitrogen and phosphorus sources, MgSO4 and most of the trace elements were found to be significant variables for PHB product...

1. The kinetic properties of the two most frequent conductance states of glycine receptor channels from somata of mouse spinal cord neurones in cell culture were investigated using the outside-out patch clamp technique. At low concentrations of glycine (0.5, 1 and 2 microM), single-channel currents were recorded with two predominant amplitudes corresponding to a dominant or main-conductance sta...

Predicting the rates of spin-dependent processes characterised by nonradiative transitions between electronic states with different spin multiplicities is important for understanding mechanisms many photochemical and catalytic reactions. To calculate these rates, it necessary to define state representation couplings that drives interstate transitions. In this work, we describe three approaches ...
