Accumulation of dust (also known as soiling) on the surface of solar panels decreases the
amount of sunlight reaching the solar cells underneath and thus the efficiency of the solar …

The paper illustrates some aspects of energy conversion processes during underground
electric train operation. Energy conversion processes are explained using exergy, in order to …

The paper presents experimental results on modelling and simulation of vehicle suspension.
Testing the performance practice of suspension dampers is performed using a device called …

The manner is illustrated in which energy conversion processes during electric train
operation can be analyzed using exergy. Loss of exergy reflects a loss of potential of energy …

The objectives of this paper consists in developing methods and technologies of command
and protection of performant static power converters for the drive systems, which meet the …

The focus of this study is to enhance the way of thinking that human activities cannot be
separated from the functioning of the entire system on Earth. Learning from Nature means to …

Within the present industrial society the humans further challenges are doubtless related to
