The effect of foundations types on the snap-through buckling of a shallow arch under a point load moving at a constant speed for quasi-static and dynamic loading is investigated. First, the static and dynamic snap-through buckling of a shallow arch resting on a two-parameter elastic foundation (Pasternak model) under a point load moving at a constant speed are studied. For quasi-static analysis, it is noted that the first four modes in the exp...

In this book you are going to know the idea of taxes mainly in Egypt. We will be able to discover the different methods of tax and relate it to the international tax concepts. At the end of this book you are going to discover what is meant by Optimal tax methods as we are trying to imply each and every method with respect to all factors related to the economic system in country like Egypt and part of the political system as well.

The three body problem is one important object of space dynamics, because this problem has many applications on space dynamics objects. Also this problem attract many scientist during last three centuries. The motion of space craft around binary asteroid can be consider as restricted three body problem so that, the treatment this object was done. Where equations of motioncan be solved by using numerical integration methods (Runge Kutta fourth ...

Master's Thesis from the year 2016 in the subject Engineering - Robotics, Mansoura University, language: English, abstract: This thesis studies strategies for humanitarian demining using robotic units. The author presents a low-cost system for landmines detection. The proposed system uses fusion of low cost multi sensors instead of using very expensive one. The proposed robot used sensor fusion technique to increase the probability of mine det...

This book based on a research conducted between September 2013 and February 2016 aiming to evaluate puretone audiometry thresholds, neuro-otological brainstem auditory evoked potential and postural instability in Parkinson's disease, and correlate the findings with disease severity and duration. I hope this work to be useful for audio-vestibular physicians, neurologists and those concerned with Parkinson's disease.

The Precambrian rocks represent 10% of the total exposed rocks in Egypt. The Precambrian rocks exposed in Eastern Desert in Egypt are composed of vast varieties of Pan-African basement rock types including metasediments, metavolcanics, gabbros, volcanics and different types of granitoid bodies. The Precambrian basement rocks are one of the economically important type of rocks, that many metallic & non metallic ores are mined from them, also th...

This book investigates the minimization of torque ripples and harmonic noises in PMSM generated due to inverter switching system. In order to reduce torque ripples and harmonic noises in PMSM, three different methods have been proposed: a new dissipative passive filter topology to reduce torque ripples and harmonic noises in PMSM derived by FOC and HDTC algorithms have been proposed.In the second method an active filter topology have been prop...
