In this paper an arm rehabilitation scenario was set-up to estimate and evaluate the principal activities of this limb by the suggested WBAN-based approach. A couple of wearable sensors mounted on the arm and a fixed node constitute the wireless network. In order to identify and classify the rehabilitation activities an algorithm based on the Received Signal Strength Indicator (RSSI), a parameter...
This paper presents an efficient hybrid method for analyzing scattering/radiation from electrically large arrays in the vicinity of nearby obstacles. Electrically large arrays are widely used in several applications such as radars, remote sensing systems, and modern communication systems. In general, these arrays radiate in the presence of nearby obstacles, such as an array on a mast. The proposed...
In this paper, an efficient method for the analysis of electromagnetic scattering/radiation from the obstacles nearby electrically large array antennas, with nonuniform excitation, is proposed. The approach is based on the combination of a ray field representation of electrically large arrays and a DFT (discrete fourier transform) based representation of array current distribution. Proposed method...
