Finding the coefficient of rolling friction (CRF) by the inclined plane method is similar to the manner used in establishing the coefficient of sliding friction. For the rolling case, the difficulty arises from the fact that the usual devices employed in angular measurements present errors greater than the effective angle. The paper surmounts...

 The paper presents different types of controlling and monitoring an industrial process through web interface, depending on the connection types made by PLC or HMI used in the process. We can control the industrial processes through HMI interface directly on the web or phone if we use a Weintek HMI in connection with a SIEMENS PLC for manipula...

The paper aims to carry out experimental research meant to increase the quality of some mass produced furniture items. In order for that to happen, a great number of size measurements have been done on beech and birch wood parts obtained through milling and drilling with numerically controlled machines. The experiment lasted for a week, with work b...

In this paper some results concerning fluid flow pattern and the evolution of flame propagation through unburnt mixture of two different hydrocarbon fuels in engine with strong macro flows were elucidated. Results presented in this paper were obtained by dint of multidimensional numerical modeling of reactive flows in very complex geometry of parti...

The most promising method for the conditions of operation of the drill string of the existing ones- is a method for predicting the durability of its elements, such as threaded lock joints (TLJ), which are based on the use of a means of individual assessment of load - indicators of fatigue. Taking into account the limited possibilities of the previo...
