The relationship between smart devices and human beings is one of the research hotspots Fourth Industrial Revolution (4IR). In this regard, we explored practical 3D electric field components measured by atmospheric apparatus (AEFA) thunderstorm activity from perspective observer. Especially, in application AEFA, a calibration method proposed to solve problem inconvenient data acquisition. First...

This paper explores the potential of solar energy generation in the area of The Hashemite University in Jordan (32.05_N, 36.06_E) by investigating the optimal inclination and azimuth angles of photovoltaic (PV) modules for every hour, day, month, and of the whole year. The object of this study is to maximize the annual energy production of PV systems by tracking the changes of sun's position in...

We consider a multiple-input-multiple-output radar system and derive a theoretical framework for the recoverability of targets in the azimuth-range domain and the azimuth-range-Doppler domain via sparse approximation algorithms. Using tools developed in the area of compressive sensing, we prove bounds on the number of detectable targets and the achievable resolution in the presence of additive ...

Contrast and gray scale stability are important attributes in determining the quality of a liquid crystal display. For LCD TVs the influence of the viewing angle is especially important. In the present paper, we use a Fourier optics based instrument to measure the gray scale behavior of different LCD displays along most of their viewing angle. The measurements can be made in luminance, color or...

ETRI Journal, Volume 27, Number 3, June 2005 This paper presents an efficient algorithm for using the two-axis magnetic compass in portable devices. The general magnetic compass module consists of a three-axis magnetic compass and a two-axis inclinometer to calculate tilt-compensated azimuth information. In this paper, the tilt error is compensated using just a two-axis magnetic compass and two...

The capability of a skywave over-the-horizon radar (SWR) to achieve the continuous observation wide range ocean dynamics parameters via single ionospheric reflection has been demonstrated by many scholars. In order expand method SWR detection parameters, simulation model an sea echo spectrum based on Barrick surface scattering cross-section (Barrick model) and 3D ray-tracing method, suitable fo...

This paper presents a novel machine-hearing system that exploits deep neural networks (DNNs) and head movements for binaural localisation of multiple speakers in reverberant conditions. DNNs are used to map binaural features, consisting of the complete cross-correlation function (CCF) and interaural level differences (ILDs), to the source azimuth. Our approach was evaluated using a localisation...
