Space-Charge Effect on the Theoretical Design of Enzil Lens
...Show More Authors

The presentwork is a theoretical study in the field of charged particle optics. It concentrates on the design of electrostatic enzil lens for focusing charge particles beams, using inverse method in designingthe electrostatic lens. The paraxial ray equation was solved to obtain the trajectory of the particles, the optical properties such as the focal length and spherical and chromatic aberration coefficients were determined. The shape of the electrode of the electrostatic lens were determined by solving poison equation and the results showed low values of spherical and chromatic aberrations, which are considered as good criteria for good design.

A Theoretical and Experimental Investigation of the Effects of Inverted Wings Modifications on the Stability and Aerodynamic Performance of a Sedan Car at Cornering
...Show More Authors
ABSTRACT<p>This research examines the impact of cornering on the aerodynamic forces and stability of a Nissan Versa (Almera) passenger sedan car by introducing novel modifications. These modifications included single inverted wings with end plates as a front spoiler, double‐element inverted wings with end plates as a rear spoiler, and incorporating the ground as a diffuser under the car trunk. The goal is to enhance the performance and stability of conventional passenger cars. To ensure the accuracy of the numerical data, the study utilized multiple methodologies to model the turbulence model, ultimately selecting the most suitable option. This involved comparing numerical data with wind tunnel experimental d</p> ... Show More

GNSS Baseline Configuration Based on First Order Design
...Show More Authors

The quality of Global Navigation Satellite Systems (GNSS) networks are considerably influenced by the configuration of the observed baselines. Where, this study aims to find an optimal configuration for GNSS baselines in terms of the number and distribution  of baselines to improve the quality criteria of the GNSS networks. First order design problem (FOD) was applied in this research to optimize GNSS network baselines configuration, and based on sequential adjustment method to solve its objective functions.

FOD for optimum precision (FOD-p) was the proposed model which based on the design criteria of A-optimality and E-optimality. These design criteria were selected as objective functions of precision, whic

Advances On Computational Intelligence In Energy
A Theoretical Framework for Big Data Analytics Based on Computational Intelligent Algorithms with the Potential to Reduce Energy Consumption
...Show More Authors

Within the framework of big data, energy issues are highly significant. Despite the significance of energy, theoretical studies focusing primarily on the issue of energy within big data analytics in relation to computational intelligent algorithms are scarce. The purpose of this study is to explore the theoretical aspects of energy issues in big data analytics in relation to computational intelligent algorithms since this is critical in exploring the emperica aspects of big data. In this chapter, we present a theoretical study of energy issues related to applications of computational intelligent algorithms in big data analytics. This work highlights that big data analytics using computational intelligent algorithms generates a very high amo

Orientalism in all its stage had wrote thousands of studies and researches about Islamic and its civilization. It didn't leave any side of Islamic culture sides without saying award in it. Orientalists have their studies in Islamic jurisprudence. The study of jurisprudence give the orientalist and opportunity to deeper understanding for Islamic society in the past and nowadays considering that it is a veal application to Islamic general thought. They search in its sources, brunches, history, development, center, ideology, and effect. For this most of orientalist writings in Islamic jurisprudence start from criticism that deny its originality which to be about to gather that Islamic jurisprudence had been affected by non– Islamic resour

China is the first Asian country in the Far East that has been invaded by a foreign power, after following a policy of isolation against the outside world. Although Britain was the first foreign power that penetrated China and had many concessions within its lands, it was not the only one that directed its interests toward china. Russia was one of the powers which were interested in China, considering the special relationships that related together the neighboring countries, like the problematic boundaries. However, after World War II, the Soviet Union tries to extend its influence and power over Asia, and China was the first country that fell under the campaign on the Soviet Union. In spite of the fact that the political role of the Uni
