A Comparative Study on the Deposition of FTO Thin Films by Conventional and Ultrasonic Spray Pyrolysis Methods for Dye Sensitized Solar Modules
Özenbaş, Ahmet Macit (null; 2017-08-27)
Fluorine-doped tin dioxide (FTO) thin films were produced via conventional spray pyrolysis and ultrasonic spray pyrolysis (USP) methods using alcohol-based solutions. The prepared films were compared in terms of crystal structure, morphology, surface roughness, visible light transmittance, and electronic properties. Upon investigation of the grain structures and morphologies, the films prepared using ultrasonic spray method provided relatively larger grains and due to this condition, carrier mobilities of t...
A comparative study on biodegradation and mechanical properties of pressureless infiltrated Ti/Ti6Al4V-Mg composites
ESEN, ZİYA; Butev, Ezgi; Karakas, M. Serdar (2016-10-01)
The mechanical response and biodegradation behavior of pressureless Mg-infiltrated Ti-Mg and Ti6Al4V-Mg composites were investigated by compression and simulated body fluid immersion tests, respectively. Prior porous preforms were surrounded uniformly with magnesium as a result of infiltration and the resultant composites were free of secondary phases and intermetallics. Although the composites' compressive strengths were superior compared to bone, both displayed elastic moduli similar to that of cortical b...

Terahertz (THz) radiation is part of the electromagnetic spectrum lying between microwaves and the far-IR. Sensing and imaging using terahertz waves is a rapidly progressing technology which has wide-range applications in different areas such as security, medicine, quality control and etc. The importance of developing passive and active devices which work in terahertz frequencies is ever more increasing in this popular field [1]. One of the most important devices in THz applications is band pass filters, wh...
A comparative study on the nonlinear behavior of chevron and suspended zipper braced steel frames
Özçelik, Ahmet Yiğit; Sarıtaş, Afşin; Department of Civil Engineering (2010)
Chevron braced steel frames require large beams to redistribute the unbalanced vertical forces exerted on the beams after brace buckling. A new frame configuration similar to chevron brace was proposed in literature, where zipper columns were attached between mid-spans of the beams from second to top story. During severe ground motion, the unbalanced vertical forces caused by buckling of lower story braces are in this case redistributed to the upper story braces by these zipper columns. Consequently, all st...
A comparative study on Kalman filtering techniques designed for state estimation of industrial AC drive systems
Akin, B; Orguner, Umut; Ersak, A (2004-06-05)
In this paper, two different Kalman Filtering techniques, Unscented Kalman Filter (UKF) and Extended Kalman Filter (EKF) are investigated and compared both experimentally and theoretically. These non-linear, stochastic observers are employed as a state estimation tool in field-oriented control (FOC) of sensorless AC drives in this work. Using the superiorities of Kalman filtering, rotor speed and dq-axis fluxes of an induction motor are estimated only with the sensed stator currents and voltages information...
