Research ArticleOpen accessIn the author namesA New Method for Multipath Clustering for Over-the-Horizon RadarAshraf M. Aziz, Senior Member, IEEE et al.Over-the-Horizon Radar (OTHR) exploits the refraction of high frequency radiation through the ionosphere layers to detect targets beyond the line-of-sight horizon. Multipath propagation between the radar and the detected targets may results in multiple spatially separated tracks for a single target to be observed at the receiver site. Consequently there is a heavy traffic, especially in case of multiple targets, … …American Journal of Applied Sciences, Vol. 13, Issue 10 · 29 Sep 2016 · 7,285 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEnergy Balance for a Diesel Engine Operates on a Pure Biodiesel, Diesel Fuel and Biodiesel-Diesel BlendsM. I. Al-Hasan, A. S. Al-GhamdiIn general, small part of fuel chemical energy transforms to effective power in diesel engines and other parts are going as energy losses, there for many researchers, as well as engine designers, are searching to increase this part by using various methods. In this study, the effect of pure biodiesel and biodiesel-diesel fuel blends on engine energy balance, compared with … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 29 Jan 2016 · 8,114 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAn Efficient Course Resolution Multiple-Receiver Approach for Reception of Slow Fading Signals in Digital Wireless Communication SystemsAshraf Mamdouh Aziz, Senior Member, IEEE et al.Multiple-receiver digital wireless communication systems employ several receivers and a digital central receiver with data fusion to reduce the effect of multipath fading problems. The multiple receiver observations are processed at individual receivers and sent to a digital central receiver. The digital central receiver fuses all the individual receiver data to form global data on which symbol was transmitted. In … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 7 Sep 2015 · 6,509 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSTUDY OF PHYSICO-CHEMICAL PROPERTIES OF THE SURFACE AND GROUND WATERA.Y. Al-Ghamdi, Mohamed El-Shahate Ismaiel Saraya, A.O. Al-Ghamdi, S.A. ZabinOf all the natural resources, water is unarguably the most essential and precious. Life began in water and life is nurtured by water. Ninety seven percent of the world’s water is found in oceans. Only 2.5% of the world’s water are non-saline fresh water. Saudi Arabia is a desert country with no permanent rivers or lakes and very little rainfall. … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 18 Apr 2014 · 7,787 accessesView PDF Cite

Research ArticleOpen accessIn the author namesThermodynamic Characteristics of Camel’s Urine as an Inhibitor for Mild Steel in 1.5 M H2SO4 Acid SolutionEhteram A. Noor, Azza A. Al-Ghamdi, Aisha H. Al-MoubarakiProblem statement: The corrosion inhibition of mild steel in 1.5 M H2SO4 by Camel’s Urine (CU) addition was evaluated at five different temperatures in the range from 30-70°C by weight loss measurements. CU acts as a good inhibitor for the corrosion of mild steel in 1.5 M H2SO4. The value of inhibition efficiency increases with increasing both inhibitor concentration and … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 22 Oct 2011 · 7,369 accessesView PDF Cite
