A method for achieving frequency synchronization between two distantly positioned high frequency oscillators is presented. The method is based on using GPS disciplined 10 MHz reference sine waves and phase locked dielectric ...

In this study, the attenuation in mobile communication due to snow and vegetation is simulated by using Discrete Propagation Model. The study includes simulation results according to different frequencies of propagating ...

This paper presents and analyses combining measurement of the RF and ELF bands of the EMF's from the external sources located around the 24 schools in Nilufer / Bursa, TURKEY throughout 2013 - 2015. The study has been ...

Electromagnetic waves caused from base stations, which are rapidly increasing due to the opportunities provided by modern technology, create an undesired effective electromagnetic pollution in the environment. Mobile phones, ...

In this study, we have presented a new approach to separate noisy components and to characterize frequency-energy variability for local real-time noisy earthquakes where epicentral distance is 0-10 degrees. This approach ...

In this study, the method to apply the Elman's recurrent neural networks using resilient back propagation for harmonic detection is described. The feed forward neural networks are also used for comparison. The distorted ...

Our environment is full of radio frequency (RF) electromagnetic radiation due to rapid progress of wireless communication technologies, which have many applications, such as base stations of mobile communication networks ...

Measurements of hydrogen plasma density, are made in a symmetric single frequency confined capacitively coupled plasma (C-CCP) RF system. Comparison is made between density measured by microwave interferometer (MWI) and ...

The wavelet transform is one of the most important method used in signal processing. In this study, we have introduced frequency-energy characteristics of local earthquakes using discrete wavelet transform. Frequency-energy ...
