Pressure vessels that are exposed to high stresses, due to unfavorable working conditions during exploitation, must be properly designed, taking into account all calculation factors, in order to be safe during their expected lifetime. Checking the condition of the vessel, or analyzing the load of the vessel in working and test conditions, is mandat...

There are many ways to accomplish optimization of machining process. In the experimental part of this paper, the optimization of machining process is accomplished from the aspect of cutting conditions, which are independent variables (speed, feed, and cutting depth), whereas the dependent variables refer to the surface roughness, more precisely, ar...

This paper deals with the numerical determination of the stress intensity factor KI for meridional cracks on the ellipsoidal head of pressure vessels. The experiment was carried out according to selected parameters, including vessel diameter, wall thickness and pressure. The analysis of the results concluded that the cylindrical segment of the elli...

Fracture mechanics is a field that is increasingly studied and applied in modern industry. One of the most widely accepted methods for assessing structural integrity in this field is the SINTAP method. Although there are many literary sources available that discuss thismethod, very few of them present its concrete application. This paper presents t...

In the time of the world’s growing need for multilingualism it is necessary to examine all possibilities for teaching foreign languages in a faster and more efficient manner. Instead of passive users, we need engineers who actively use foreign languages. CLIL is an approach that insists on economization of time needed for foreign language acq...

In this paper, a differential equation is derived that gives the relationship among the Loschmidt constant, the Avogadro constant, and the speed of sound in real gases as a function of the thermodynamic properties of the gas (pressure, temperature, and volume). The constant ratios NL/NA and the relative deviation of the NL/NA ratio from the mean va...

This paper shows optimization by using the Monte Carlo method, the mathematical model of roughness, or the mean arithmetic deviation of the profile. Optimization means finding the best of all possible solutions. According to the experiment plan, an experimentwas previously performed. Based on the results of the experiment and the plan matrix, the c...

3D scanning and 3D printing finds more and more application in digitalization, presentation and replicas making of different artworks. In this paper the capabilities of these technologies are represented on the example of a selected sculpture from Smrike national monument. Polygonal 3D model of the sculpture is made by using a manual 3D scanner. Us...
