CALCULATION OF RELIABILITY OF TYPICAL COOLING SYSTEM BY DESIGNING OF TREE FAILURE METHOD
In the introductory part we give definitions and relationships to determine the reliability and probability of failure of technical systems. After that, the analysis and calculation of reliability, we proposed method, based on the construction of tree failure in the form of logical structure. The second part was performed to verify the model set on...

HEAT TRANSFER THROUGH FLAT WALLS COMPLEX PROMBLEMS SOLVING BY ELECTRICAL ANALOGY
Starting from the Fourier's law for stationary heat transfer and Ohm's law for DC through the resistor, the paper presents the analogy between thermodynamic and electrical quantities. Based on this analogy, has been used knowledge of circuit theory for of the heat transfer through walls in the multilayer characteristic positions to derive the schem...

A FUNCTION PROPERTY OF POLYTROPHIC PROCESS WITH ASPECT OF TANGENT CONSTRUCTION
In this paper, starting from general tangent equation in arbitrary point of specified curve, using principles of differential geometry and given mathematical transformation tangent equation of polytrophic function in p – v diagram was obtained. This form is convenient for solving numerous practical and theoretical problems in engineering ther...

QUALITY ANALYSIS OF BASIC RESOURCES FROM THE ASPECT OF FEASIBLITY OF ALUMINA CEMENT PRODUCTION
Main objective of this paper is feasibility of alumina cement production on the Republic of Srpska resources basis. As is known calcium-alumina cement is type of mineral hydraulic binder. As basic resources of CAC production are used bauxite and calcite. There are two main production processes: the fusion, Al2O3 less than 50% and the sintering...
