thermal contact conductance (tcc) between an exhaust valve and its seat is one of the important parameters to be estimated in an internal combustion engine. an experimental study presented here to acquire temperature in some interior points to be used as inputs to an inverse analysis. an actual exhaust valve and its seat are utilized in a designed and constructed setup. conjugate gradient metho...

The syntheses of novel hydrazono acyclic nucleosides similar to miconazole scaffolds are described. In this series of acyclic nucleosides, pyrimidine as well as purine and other azole derivatives replaced the imidazole function in miconazole and the ether group was replaced with a hydrazone moiety using phenylhydrazine. To interpret the dominant formation of (E)-hydrazone derivatives rather tha...

A set of quality criteria is proposed to evaluate the performance of genetic algorithms for optimization. Instead of concentrating solely on the best solutions proposed by the algorithm, the quality criteria also consider the repeatability of the optimization and the coverage of the search space. They are tested by using various parameter settings of a genetic algorithm providing starting struc...

The drift velocities of spiral waves driven by a periodic mechanic deformation or a constant or periodic electric field are obtained under the weak deformation approximation around the spiral wave tip. An approximate formula is derived for these drift velocities and some significant results, such as the drift of spiral waves induced by a mechanical deformation with v53v0 , are predicted. Numeri...

We discuss a translation of financial reports from the XBRL format into Semantic Web language OWL. Different from existing approaches that do mechanic translation from XBRL’s XML schema into OWL, our approach can faithfully preserve the implicit semantics in XBRL and enable the logic model of financial reports. We show that such a translation reduces the risk of redundancy and inconsistency, an...

This article describes preliminary work on a research environment called Virtual Synergy to represent a shared virtual map of an area for multiple autonomous robots by modifying the GameBots 3D multi-agent system. The use of GameBots wil l allow multiple users to interact with robots and agents at different levels of adjustable or dynamic autonomy. By interacting with the robots as another team...

Warts are benign epithelial neoplasms of the skin and mucosa resulting from human Papilloma virus (HPV) infection. They are a common dermatologic complaint, with an estimated incidence of 10% in children and young adults [1]. The treatment is challenging and there is no single therapy established as completely curative [2]. In this report we presented a case of successfully removed resistant pl...
