A theoretical design assessment performed here to evaluate the idea of utilizing wave energy in the Red sea to power electric-cargo ships, in the route between Port Sudan and Jeddah Islamic port. The calculated mean wave power in 2018 was (1.4 MW), five wave p…

Decision making is a mental process in which one of the different options is chosen. All decision-making processes end with a decision. In this thesis, site selection for a new project was examined. Investments requiring very high budgets, such as the construc…

In the phases of hydrological model calibration, the impact of control parameters of optimization algorithms on the related fitness (cost) function (reaching the global solution correctly and expeditiously) is rather essential. These control parameters’ dynami…

In this study, the effects nano-SiO2 and nano-Al2O3 on cement mortars were experimentally studied. The percentage of nano-powders were used as 1%, 3% and 5% into the material. Different types of analysis were used to nano-powder’s impact on the cement mortars.…

Anti-thyroid drugs are relatively simple molecules known as thionamides, which contain a sulfhydryl group and a thiourea moiety within a heterocyclic structure [1]. Methimazole (1-methyl-2-mercaptoimidazole) is widely used drug in medicine for treatment of hyp…

Many structures, machinery, equipment, heritages, also socio-cultural systems may be subjected to the unfavourable impact caused by various disaster risks, such as flooding, heavy snow, earthquakes, landslides, hurricanes etc. For prevention and reduction of d…

This paper presents the theoretical aspect of the creep behavior in materials, particularly in metallic materials. Different creep mechanisms were displayed. The main models developed to determine or extrapolate the rupture time of materials were presented. So…

In this study, a single switch cascade DC/DC boost converter has been preferred instead of conventional cascade DC/DC boost converter to reduce cost and provide simple system control. High-performance controller design for DC/DC converters is the most importan…
