OBJECTIVE To evaluate the effects of strain rate and temperature on the mechanical properties of resin composite restorative materials (RCs) and to investigate the construction of temperature--strain rate equivalence 'master curves'. METHODS Four visible light-cured resin composite RCs, all of shade A3, were used: Heliomolar Radiopaque (HR) and Tetric Ceram (TC) (Ivoclar, Schaan, Liechtenstei...

The settlement drag coefficient of non-spherical particles (SDCNPs) is a crucial parameter in the field petroleum engineering. Accurately predicting SDCNPs fluid essential to selection and design proppant hydraulic fracturing scheme. Although many models for anticipating have been proposed, none them can be adopted non-Newtonian (NNF) Newtonian (NF). In investigation, NF NNF are studied experim...

Propositional directed acyclic graphs (PDAG) continue the line of research on knowledge compilation in the context of Negational Normal Forms (NNF) and Binary Decision Diagrams (BDD). This paper summarizes previous results and open problems concerning knowledge representation based on PDAG and its sub-languages. In addition, it gives a short introduction to some application areas.

One of the major problems in multiple target tracking is to obtain an accurate association between targets and noisy measurements. We introduce a new scheme, called Constrained Optimal Data Association (CODA), that finds the optimal data association by a MAP estimation method and uses a new energy function. In this scheme, the natural constraints between targets and measurements are defined so ...

Medicine Paring Analysis is one of the most important tasks in the research of Traditional Chinese Medicine Prescriptions. The most essential and difficult step is to mine associations between different medicine items. This paper proposes an effective approach in solving this problem. The main contributions include: (1) proposing a novel data structure called indexed frequent pattern tree (IFPT...

A negation normal form (NNF) is a circuit on unbounded fanin conjunction (AND) and disjunction (OR) gates, with fanin one negation (NOT) gates applied to input gates only. A NNF is decomposable (DNNF) if, for each AND node, the subcircuits rooted at the children of the node are variable disjoint. We prove an unconditional exponential lower bound on the DNNF size of CNF formulas; thus far, only ...

UNLABELLED Advances in all-ceramic systems have established predictable means of providing metal-free aesthetic and biocompatible materials. These materials must have sufficient strength to be a practical treatment alternative for the fabrication of crowns and fixed partial dentures. OBJECTIVES The aim of this study was to compare the biaxial flexural strength of three core ceramic materials....

This study was conducted to evaluate the compressive strength, compressive fatigue limit and the amount of fluoride released from the Smart Dentin Replacement SDR TM restorative material in comparison to another fluoride released from hybrid resin composite material Tetric N Ceram. A total of eighty (80) specimens were used in this study, where forty (40) specimens were used to evaluate the com...
