Background: This study aims to evaluate the negative health impacts of exposure to electromagnetic field and to prepare a risk map of two selected call centers. Materials and Methods: Two call centers whose electromagnetic field values were measured by calibrated low high and point frequency measurement device. The measurements were performed by following the EN 50492 Standards. 178 employees ...

We present methods to measure the spatial, angular and depth resolution of LF displays using off-the-shelf equipment and performing a subjective experiment. The spatial resolution is measured in circles per degree and the challenge is to display and quantify sinusoidal patterns with varying spatial frequencies on displays, which in general do not exhibit regular or pixel-like structure. Being s...

This article reviews the use of gyroresonance emission at radio wavelengths to measure coronal magnetic fields. The spiralling motion of electrons in the 200– 2000 G fields in the solar corona produces sufficient opacity to render the corona optically thick, making it easy to recognize such sources in microwave images from their coronal brightness temperatures. Where gyroresonance sources are p...

Emissivity measurements were made during the ReSeDA experiment. Emissivities are necessary for obtaining surface temperatures from remote sensing data in the thermal infrared, and they enter the radiative balance in the atmosphere-surface system. The objective of this study was to assess the spatial variation of surface emissivity in the area, with special regard to the spectral variation of em...

-As reported in [1], the Material Characteristics in Frequency Domain coupled with a 2 layer feed-forward Neural Network, MCFD/NN, has been successfully applied to soil moisture determination. The results were obtained under controlled laboratory conditions. Extension to open field soil moisture determination has been reported in [2] and it was shown that the MCFD/NN approach gives accurate res...
