Abstract: The Jordan Valley’s territorial extent is defined for this study as an elongated stretch of border area, located west of Jordan’s boundary with the West Bank, Palestine. This region along with the West Bank was conquered by the Israeli Army during the June 1967 War and has been held by Israel since. Almost 88% of its 200,000 Palestinian population then living in the region were expelled and turned overnight into refugees in Jordan and elsewhere. In the subsequent 56 years since, the region, declared by Israel as a highly militarized zone, has often been discursively publicized as the front line of Israel’s eastern defense. This paper seeks to refute such a notion that indirectly gave Israel justification to subject the remaining Palestinian inhabitants residing there (currently numbering ca. 60,000) to a harsh discriminatory regimen of surveillance and control under military occupation. At the same time, the Israeli government has over decades privileged the ca. 10,000 incoming Jewish settlers, now living in some 30 Israeli Jewish settlements in the Jordan Valley. Employing a grounded theory approach in our study provided an opportunity for the local Palestinians to have their voices heard, shedding needed analytical light on their difficult situation on the ground.2023-04-22T00:00:00ZEffect of Dust Storm Intensity Variations on Total Path Attenuation Prediction

Title: Effect of Dust Storm Intensity Variations on Total Path Attenuation Prediction
Authors: Elsheikh, Elfatih A. A.; Rafiqul, Islam Md.; Habaebi, Mohamed Hadi; Zyoud, Alhareth; Suliman, F. M.; Eltahir, E.I.; W. A, Nadir
Abstract: This paper proposes a novel dust-storm total path attenuation prediction model. This model is formulated as a function of specific attenuation (dB/km) and the effective distance, which considers the non-uniform dust storm intensity variations throughout the link. The effective distance is obtained as a combination of the total link distance and the reduction factor. The reduction factor is developed based on the modeled 2-D structure of the observed dust storm characteristics. A measurement campaign of atmospheric characteristics, their properties, and effects on several microwave links operated in Khartoum-Sudan was conducted. In an earlier report, an empirical dust storm attenuation prediction model was proposed based on short-distance links by assuming uniform dust storm intensity variations. However, it was observed that the dust intensity varies with the distance, which affects total attenuation, and this issue is not addressed yet. One year measurement on the 6.2 km and 7.6 km long microwave links operating at 21.2 GHz and 14.5 GHz are used to validate the proposed dust storm total path attenuation model.2021-12-01T00:00:00ZMaximum Power Point Tracking Controller Technique Using Permanent Magnet Synchronous Generator

Abstract: In this research, Maximum Power Point Tracking (MPPT) control was applied to capture the maximum possible power from Permanent Magnet Synchronous Generator (PMSG). The Wind Energy Conversion System (WECS) was applied using Simulink tools in MATLAB. The parameters of WECS tuning to reach the unity power factor, thus it can capture the maximum possible power from WECS. Simulation results show that wind speed plays an essential role in rotor speed and electromagnetic torque due to the proportional relation between wind speed and power.2021-12-01T00:00:00ZThe Simplest Estimation Method of Weibull Probability Distribution Parameters

Title: The Simplest Estimation Method of Weibull Probability Distribution Parameters
Authors: Badawi, Ahmed Samir; Ouda, Mohamed; Zyoud; Alhareth; Yusoff, Siti Hajar
Abstract: This study aims to calculate the parameters of Weibull distribution based on a simple numerical analysis method. Two numerical analyses methods; Empirical Method (EM) and Method of Moments (MOM) are compared in this research based on the simplicity of the numerical analysis. Wind speed data was measured and analysed from January 2014 to December 2015 in Ashqelon city, Palestine as a sample of actual data. Based on the shape factor “k” and scale factor “c” the probability distribution curve can be determined to estimate the potential of wind energy. Moreover, it can be used in selecting the best location for installing wind turbine generators.2021-12-21T00:00:00Z
