Thesis under the supervision of Prof. D. Karnopp, Prof. M. El Araby, and Dr. E.M.ElBeheiry, on "Integrated Active System for Emergency Maneuvers in Automobiles"
The subject includes modeling of passenger cars for dynamic analysis, lateral dynamics and control of vehicles, sliding mode controllers, Fuzzy logic controllers, Neural networks for friction coefficient identification between tire and road surface, driver's model using fuzzy inference for driver-in-the-loop simulations.
The subject includes modeling of rotor-bearing systems, Lumped and continuous field modeling, Critical speeds, stability prediction, and unbalance response. Investigations were carried out for both symmetrical and non-symmetrical bearing characteristics.
Ranked first in class.
Courses include: Mathematics (Calculus, Linear Algebra, Differential Equations...etc), Physics, Thermodynamics, Fluid Mechanics, Automatic Control, Mechanical Vibrations, Theory of Machines, Mechanical Design, Linear Programming, Electrical Circuits, Robotics,...etc.
Awarded a Full-mark grading (200/200) for the graduation project entitled: Fesibility Study for Qattara Depression, An Engineering Prospective.
A model-based methodology for assessing flight simulator fidelity in closed-loop fashion is exercised in analyzing rotorcraft low-altitude maneuvers for which flight test and simulation results were available.
The project includes the development of a comprehensive computer program using (MATLAB/SIMULINK), for the design of vehicle-pilot model dynamics. The program was capable of predicting the HQSF (Handling Qualities Sensitivity Function) and PIO (Pilot Induced Oscillation) ratings. The research efforts have resulted in some publications as well as the development of (PVDnl), an interactive computer program for modeling the human pilot in single axis tracking tasks. The program have been distributed to approximately 20 research organizations world-wide, such as Boeing, NASA Ames, NASA Langley.
Ten years of teaching experience in courses such as Mechanical Vibrations(see www.geocities.com/cairo_vibration) , Automatic Control and Robotics, Theory of Machines, Neural Networks, Fuzzy Logic, System Identifications...etc
The project was supervised by Prof. H. Koivo, Automatic Control Department, Tampere university. The subject included the training as well as the research on multi-input multi-output PID controllers.
Developed a computer data base system for company administrations.
