The paper presents a novel form of acceleration detection which is suitable for use in hydraulic amplification stages for relatively low frequency, high power output servo systems. The acceleration detector was developed as part of a research program concerned with the development of a servo assisted pantograph to provide improved current collection on high speed electrified railways.

The continuously increasing performance data of the modern diesel engines as well as the fulfillment of the very restricted emission standards cannot be realized without the aid of the turbocharger. Due to the prevalence of the turbo charged engines the customer’s attitude to the emitted noises has been changed. The customer wishes a high power output, but no longer wants to hear it. Thus the consideration of the noise characteristics during the development work is recently as important as the thermodynamic or durability issues. This paper deals with different turbocharger noises, describes its sources, transmission routes and possibilities of noise reduction.

According to popular belief, air temperature effects on wind turbine power output are produced solely by air density variations, and power is proportional to air density. However, some cases have been reported, all involving stall-controlled wind turbines, in which unexpected high power output was observed at very low temperatures.As a preliminary study, this article intends to quantify the influence of air temperature on the power production of the Tacke TW600 wind turbine installed in Tiverton, Ontario, Canada. Increases in power output due to air temperature variation are stratified by wind velocity, showing that these increases are below the theoretical limits of air density variations during operation in low winds and are comparable to and beyond those theoretical limits at higher wind velocities. At – 9°C and 0°C, narrow bands of power at distinct levels are observed in the stall regime of the turbine; they are typical of many stall phenomena observed on stall-controlled rotors, but these levels have been found to be independent of any parameters recorded.
