As the world moves towards CO2 emissions reduction the creation of alternative means of transport primary energy forms. One of the promising energy forms - electric, effectively transferred to mechanical energy by electric motors. Problem analysis of regenerative energy usage for total energy consumption is performed and selected as research object...

In this study, a permanent magnet synchronous generator (PMSG) topology with compensated reactance windings in parallel rod configuration is proposed to reduce the armature reactance XL and to achieve higher efficiency of PMSG. The PMSG was designed using iron-cored bifilar coil topology to overcome problems of market-dominant rotary type generator...

This study presents the results of electromagnetic feld parameters measurements in an open area under different air temperature and humidity conditions. An attempt to consider the electromagnetic wave as a holistic harmonic oscillation, which takes into account all frequency components of the field at the measurement point, was also presented in th...

Bioremediation is one of the most efficient and widely applied methods of biotechnology, which also plays an important role in cleaning the environment from pollution by oil and oil products as well as rehabilitating the soil. Time is a limiting factor which prevents the effective use of biological treatment method, since the biodegradation of oil...

In this paper, wind speed measurements are considered for Mardin region in Turkey. Mardin city is situated in East part of Turkey. Mardin is a mountainous area suitable for wind. And also, its wind energy potential is at an acceptable level. Wind speed data in this study, is obtained from the national meteorology station. This real-time measured da...

In this study, current situation of natural gas and its geo-energetics in our country are analysed and its supply and demand equilibrium is compared. Today, some factors such as its cheapness relatively to many other kinds of fuel, high efficiency, easiness of its use, demand flexibility and low investment cost brought natural gas use into the f...

In this study, a wind speed data of the Kirklareli region of Turkey is considered and Hurst parameter is calculated for this data. For this purpose at first statistical parameters of the wind speed data are calculated. And, as a result of this analysis it is determined as a non-gaussian distribution. After that, it is shown as Weibull distribution...

In this study, ceramic plate behaviour was elaborated on the basis at sound signal variations caused by the impact. All tests were performed using plate specimens and pendulum testing station; with date acquisition and analysis systems. Two various methodologies such as; spectral and statistical were used. In the spectral analysis, power spectral d...

The paper considers the issue of control of linear springless oscillating electrical motor by means of FFT analysis data of motor total current. The main idea of this control is the usage of relationships between harmonics information and oscillation velocity, distance; the controller would calculate the control signal for the next period. This con...

In various appliances and equipment of sundry transport means there is a lot of diverse mechanisms of periodical movement. So, the various piston or membrane pumps of fuel feeding and lubrication systems, circulation pumps, air and refrigerating coolant compressors, etc. are the typical examples of innovative and well promising application of the o...
