Design and simulation of solar grid-connected charger for electric vehicles

© 2018 IEEE. Electric Vehicles (EV) are playing major role in decreasing carbon emissions. The major problem so far with the Electric Vehicles are overloading the Distribution Grids and availability of enough charging stations. The main objective of this research is to design and install a solar powered charging station for EVs in the UAE environment. This research aims to focus on the need for the shifting from the traditional gas and petrol vehicles to Electric vehicles in the UAE. Additionally, the project intends to ease the problem of the additional load that these EVs impose on the grid by powering the charging station from solar energy. This will help evolve the existing transport system of the UAE into a cleaner and greener system. The project is divided mainly into three important parts. First of all, the system components are designed to match with the ratings of available most common EVs. Then the system has been modelled in DIgSILENT Power factory for the simulation and validation of design. Finally, the results from calculations and simulations are described and compared

The Arab Gulf countries and the Arab- Israeli conflict;: the linkages and dynamics (1970-2000)

This thesis examines the changing linkages and dynamics of the relationship between the Arab Gulf countries and the Arab-Israeli conflict through the period of 1970-2000. The Arab Gulf countries' level of involvement in supporting the Arabs and Palestinians in the Arab-Israeli conflict diminished throughout the period of study. The thesis explains this diminishing role by discussing the impact of the developments of international struggle for influence in the Gulf as well as the Israeli ambitions and relations to the Gulf region, largely expressed through the Israeli relationship with Iran under the Shah. The thesis shows that the years 1973, 1979 and 1990 formed important turning points for international influence in the region. These turning points influenced on the level of the Arab Gulf countries' involvement in the Arab-Israeli conflict. Throughout the seventies, the Arab Gulf countries played an active role in supporting the Arab side in the Arab-Israeli conflict. The clearest expression of this support was the implementation of the oil embargo against the West during the October 1973 War. The eighties witnessed the birth of the Gulf Cooperation Council (GCC), the formation of which symbolized the emerging security challenges within the Gulf region. These security challenges represented by the Iranian Revolution, the Iran-Iraq war and the Soviet invasion and occupation of Afghanistan exhausted most of the capabilities and efforts of the Arab Gulf countries. Their focus and attention shifted away from the Arab-Israeli conflict, in spite of the serious and dramatic developments in that conflict. The repercussions of the Iraqi invasion of Kuwait in 1990 resulted in a further diminishment of the role of the Arab Gulf countries in backing the Palestinians in the Arab-Israeli conflict. Only after September 2000 and the beginning of the Second Palestinian Intifada did the Arab Gulf countries again play a vital role, by means of financial, political and media support. The thesis explains the linkages between security in the Gulf and the Arab- Israeli conflict. It examines the hypothesis that a reciprocal relationship explaining the level and type of Arab Gulf countries involvement in the Arab-Israeli conflict has existed throughout the period of the study

Fecundity of mosquitofish, Gambusia affinis (Baird & Girard) as a function of female size in fish from two lakes in Libya

The re!ationships between length and weight of the female Gambusia affinis and location with the fecundity (eggs and eyed embryos) were analysed. The weight of fish was the most accurate predictor of fecundity: the heavier the female, the larger was their fecundlty. The brood fish from BuDezera produce double the number of eyed embryos per 0.01g weight increase, cornpared to brood fish from Ain Ziana. In genera!, fish frorn BuDezera has fecundity higher than fish of tke same weight grocp from Ain Ziana lake. Fisk length was also positively correlateci with fecundity, but nct as closely as weight.

Meristic and morphometric characters of Saurida tumbil (Actinopterygii: Aulopiformes: Synodontidae) from Iraq

Morphometric and meristic characters of the greater lizardfish Saurida tumbil were examined from the marine waters of Iraq, Arabian Gulf. Eight morphometric (in the percentage of the total fish length) and six meristic traits have been analyzed. No significant differences were observed between male and female fish specimens, except for length of dorsal fin and predorsal length, which have shown isometric growth; the rest of the morphometric characters showed negative allometry. This study provides data to fishery biologists regarding the morphometric traits of S. tumbil, for conservation policies of this fish species of Iraqi waters

Three Dimensional Mapping of Texture in Dental Enamel

We have used synchrotron x-ray diffraction to study the crystal orientation in human dental enamel as a function of position within intact tooth sections. Keeping tooth sections intact has allowed us to construct 2D and 3D spatial distribution maps of the magnitude and orientation of texture in dental enamel. We have found that the enamel crystallites are most highly aligned at the expected occlusal points for a maxillary first premolar, and that the texture direction varies spatially in a three dimensional curling arrangement. Our results provide a model for texture in enamel which can aid researchers in developing dental composite materials for fillings and crowns with optimal characteristics for longevity, and will guide clinicians to the best method for drilling into enamel, in order to minimize weakening of remaining tooth structure, during dental restoration procedure
