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...

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...

A major objective of tribological researches is characterisation of rolling friction, due to various cases encountered in classical engineering applications, like gear transmissions and cam mechanisms or more recent examples met in bioengineering and biomedical devices. A characteristic of these examples consists in reduced dimensions of the contac...

The braking system is one of the most important and complex subsystems of railway vehicles, especially when it comes for safety. Therefore, installing efficient safe brakes on the modern railway vehicles is essential. Nowadays is devoted attention to solving problems connected with using high performance brake materials and its impact on thermal an...

The paper presents a comparative analysis between experimental results and modelling in order to interpret the value of the contact pressure on the asymmetric longitudinal rolling. It is also intended action and the different behaviour of upper cylinder compared to the lower cylinder action in situations when both are driven, or only one operates. ...
