Similarity has become a classical tool for ontology confrontation motivated by alignment, mapping or merging purposes. In the definition of an ontologybased measure one has the choice between covering a single facet (e.g., URIs, labels, instances of an entity, etc.), covering all of the facets or just a subset thereof. In our matching tool, OLA, we had opted for an integrated approach towards s...

This research investigates the implementation mechanism of block-wise ILU(k) preconditioner on GPU. The block-wise ILU(k) algorithm requires both the level k and the block size to be designed as variables. A decoupled ILU(k) algorithm consists of a symbolic phase and a factorization phase. In the symbolic phase, a ILU(k) nonzero pattern is established from the point-wise structure extracted fro...

This paper presents practical methods for computation of disturbance rejection measures, which are useful for assessing the dynamic operability of the process. Using L1 optimal control theory, we consider the cases of steady-state, frequency-wise and dynamic systems. In comparison to the available methods, the proposed approach ensures that a linear, causal, feedback-based controller exists tha...

This paper presents practical methods for computation of disturbance rejection measures [1], which are useful for assessing the dynamic operability of the process. Using L1 optimal control theory, we consider the cases of steady-state, frequency-wise and dynamic systems. In comparison to the available methods [2–4], the proposed approach ensures that a linear, causal, feedback-based controller ...

BACKGROUND AND AIM: Sesame has a high content of calcium. Regarding to the lack of adequate data about its remineralizing potential, we conducted this study to evaluate the surface hardness of enamel exposed to sesame extraction gel in comparison to artificial saliva and fluoride.METHODS: After mounting and polishing twenty-four caries-free human premolars, the baseline microhardness was record...
