Kelvin-Havelock source
Opis:: This paper discusses the numerical evaluation of the hydrodynamic characteristics of submerged and surface piercing moving bodies. Generally, two main classes of potential methods are used for hydrodynamic characteristic analysis of steady moving bodies which are Rankine and Kelvin-Havelock singularity distribution. In this paper, the KelvinHavelock sources are used for simulating the moving bodies and then free surface wave patterns are obtained. Numerical evaluation of potential distribution of a Kelvin-Havelock source is completely presented and discussed. Numerical results are calculated and presented for a 2D cylinder, single source, two parallel moving source, sphere, ellipsoid and standard Wigley hull in different situation that show acceptable agreement with results of other literatures or experiments.

Opis:: Many oxides are applied as a catalysts for commercially important processes. Recently, decomposition of nitrous oxide into nitrogen and oxygen have became a topic of vital interest for catalytic chemistry. Two possible ways of deN₂O reaction, low temperature and high-temperature, can be distinguished. Promising results were obtained for spinel oxides which contained cobalt. Because of cationic redox route, triggered by electron transfer, of N₂O decomposition over these oxides, investigation of their electronic properties was justifi ed. Th erefore the work function measurements, using Kelvin method were carried out. Moreover in-situ monitoring of processes occurred at catalyst’s surface was performed using mass spectrometry.
