EDUCATION AND TRAINING
14 Sep 2002–12 Jul 2007 B.Sc. Communications & Electronics Engineering Assiut University - Faculty of Engineering, Assiut (Egypt)
Main Subjects: Digital Communications, Modulation/Demodulation Schemes, Multiple Access Techniques, Multiplexing, Networking, GSM, UMTS, Antennas and Radar Systems, Microwaves and Fiber optics, Assembly, Fortran, Pascal, Matlab, Analog communication, Digital communication, Electronic circuits, PLC, Local Area Networks (LAN), Digital exchanges, Digital design for logical circuits, Digital signal processing (DSP), Microprocessor interfacing.
Graduation Project: Emergency Telemedicine Biomedical System (Wireless Electro Cardio Graph) This project won the first prize in the Youth Week of Egyptian universities in 2007 and has participated in many conferences and competitions and has been highly appreciated. The project was to build a wireless ECG that extracts the heart signal from the human being and converts it to a digital format that is transmitted wirelessly through the mobile phone of the patient over the cellular network to the mobile phone (of the doctor) using a Data SIM card. The mobile phone at the receiver end (Doctor/Physician in this case) is connected to a computer through the USB/Serial port, where a Matlab software recognizes the signal and displays it in a GUI interface as well as saving this signal in the database along with the patients’ other data. My role included: ▪ Implementing the analog module required in the acquisition of the heart signal. ▪ Sharing ideas with the software interface and the database structure teams ▪ Developing the connection with the mobile phone receiver via the USB and Serial port. ▪ Leading the team responsible for the heart signal conditioning.
