Design and realization of A 0.5-5 GHz cascaded feedback amplifier
Korkmaz, İbrahim Cem; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2015)
Wideband amplification is one of the most examined study areas in microwave engineering. In this thesis work, 2-stage amplifier operating in decade bandwidth of 0.5-5 GHz is designed, simulated and demonstrated using two different discrete transistors. Designed amplifier is based on cascaded feedback amplifier concept. In order to flatten the gain of the designed amplifier, feedback topology is applied to both stages. Primarily, first stage is designed and demonstrated with flat gain of 7.8±1.2 dB and minim...
Design and construction of an interferometric setup for dynamic measurement of clearances inside plain bearings
Jafari-Tabrizi, Atae; Dursunkaya, Zafer; Department of Mechanical Engineering (2017)
In this work with the help of fiber optic interferometry an experimental framework is designed and constructed to dynamically measure micron-level clearances inside main journal bearing of an engine crankshaft, and the trajectory of its shaft. For this purpose, the crankshaft is rotated at lower speeds than its operating speeds. An electric motor is used to rotate the crankshaft, and there are no pistons and connecting rods connected to the crankpins. Measured clearances from multiple points of the bearing ...

Design and construction of a cw mode nd:YAG laser prototype
Eryılmaz, Ertan; Esendemir, Akif; Department of Physics (2004)
In this thesis a theoretical background of Nd:YAG lasers has been presented and key parameters of a design have been stated. Both pulsed mode and CW mode designs have been made; a 500mJ xenon flash lamp has been investigated as the pulsed light source and a 500W tungsten halogen lamp has been used as the continuous light source for optical pumping. Closed cooling system has been constructed. De-ionized water has been used as coolant. The goal has been acomplished by constructing a CW mode prototype. The out...
