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

The DSWIG scheme proposed in this paper uses an inverter with apparent power lower than the corresponding generator power. The expected ratio between the inverter power and the generator power is 50% in the case of DSWIG. This is similar to DFIG applications. The advantage of DSWIG is the lack of brushes. DSWIG can be used in variable speed applica...

 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...
