The use of ceramic materials in thermal pulverization technique has led to a massive enlargement of the range of areas in which they find their use. Due to the large hardness, the dielectric properties, the resistance to high temperatures, ceramic materials find many applications in areas such as the automotive industry, the aviation industry, the ...

Drying is one of the most important operations in the food and processing industry, primarily because of maintaining the quality of foods intended for storage and use over a longer period of time. Therefore, this process is justifiable to use wherever possible, and most often for drying fruits, vegetables, medicinal herbs, etc. The process of dryin...

This research introduces the theoretical and experimental study of the plastic deformation through drawing of the copper wire, the presentation of the microstructures resulting after each drawing, certain possible flaws which occur within this plastic deformation process and the conclusions on the grains` flip- over and elongation. During the drawi...

This paper deals with a problem of finding the right address in the new city or unknown part of the city, the right door. The psychological pressure on people in this situation can be quite large and unpleasant, especially when the GPS could not provide enough support. The outdoor position systems are based on GPS signal and besides that, they are ...

 The paper deals with the problem of determining the stator end winding inductance of A.C. machines. It refers to the two-layer windings with shortened pitch, the relative pitch being less than one. The inductance has been determined by numerical analysis based on finite elements method (FEM), the procedure being described in this paper. In or...

 In order to model natural phenomena, a faithful model describing the evolution of the analyzed phenomena must consider as many aspects as possible. An advantage of a correct representation of the studied phenomenon is the highlighting of the aspects hard to notice initially. To support these affirmations, two examples are brought into attenti...

In this article we obtain some numerical results for the considered problem u'' - u' + (-u^2 + 1)e^(-1/(1+u)) = 0 on [0,1] u'(0) - u(0) = 0u'(1) = 0 This problem arises from the theory of adiabatic tubular chemical reactors. To solve the problem from above we applied a common fixed point result for non-deceasing and weakly increasing operators i...

In this paper we present a technological problem encountered in the machining accuracy of the parts for aerospace, made of aluminium alloy extruded profile with 7 meters length. Those parts have very tight tolerances and on milling process appear deviation due to thermal expansion effect, that influence the repeatability of machining processes. Thr...
