Non-destructive testing of internal structure of the low-quality wood

Radiographic non-destructive examination of the round timber became a popular technique in the middle of the twentieth century when radiography was first applied to study the structure of materials. The X-ray television testing equipment is widely used in non-destructive inspection for a long time, but up to now, this equipment was not applied to find the heartwood rot in wood sticks of any diameter. This article analyzes the innovative method of non-destructive testing of low-quality wood, which was performed using the portable X-ray television testing system. Furthermore, it provides positive results of experimental investigations. In addition, this article describes possibility of taking quality images of the internal structure of wood, as well as possibility of the automated image processing. © IAEME Publication

Organization of search for the optimum shape of the blades assembly for power plant

Abstract: The paper considers the exploratory search for the optimum shape of the blades assembly for power plant in terms of power load. To find the optimum area we apply a set of algorithms for power plant modeling and visualization elaborated before and presented in a form of technological chain. The results of exploratory parametric search allow to find needed directions for variation of key geometric parameters. Thus, considering the technological restrictions on the geometric parameters we find optimum zone in the space of the parameters that determine the shape of the blade assembly.Note: Research direction:Mathematical modelling in actual problems of science and technic
