Improvement of light emission from Tb-doped Si-based MOS-LED using excess Si in the oxide layer
Kulakci, Mustafa; Turan, Raşit (2013-05-01)
The fabrication of efficient silicon-based Light Emitting Devices (LEDs) is extremely important for the integration of photonic and electronic components on the same Si platform. In this paper, we report on the room temperature electroluminescence properties of Tb-doped MOS-LED devices with an active layer of SiO2 and Si-rich SiOx produced using the magnetron co-sputtering technique. The electroluminescence properties of both types of devices were studied as a function of processing conditions and material ...
Improvement of structural characteristics of composite thin-walled beams using variable stiffness concept via curvilinear fiber placement
Farsadi, Touraj; Bozkurt, Mirac Onur; Çöker, Demirkan; Kayran, Altan (2021-01-01)
This study presents the use of variable stiffness concept via curvilinear fiber placement to achieve improved structural characteristics in composite thin-walled beams (TWBs). The TWB used in the study is constructed in circumferentially asymmetric stiffness (CAS) configuration. The variation of fiber angles along the span and the width of the TWB is included by defining two fiber path functions. A parametric study is performed to investigate the effects of different fiber paths on the structural performanc...
Enhancement of the reliability of MEMS shock sensors by adopting a dual-mass model
Fathalilou, Mohammad; Soltani, Kamran; Rezazadeh, Ghader; Ciğeroğlu, Ender (Elsevier BV, 2020-03-01)
MEMS shock sensors are widely used with applications ranging from aircraft to electrical measurement systems. They are designed to operate at the shocks above a predefined threshold level. The conventional single-mass switches may lose their reliability at shock levels smaller than the threshold, if experience smaller unwanted pulse duration. This paper has proposed a dual-mass switch with auxiliary mass-spring attached to the main system which increases the reliability of the sensor against the unwanted pu...
Enhancement of the bottoming cycle in a gas/steam combined cycle power plant
Safyel, Zerrin; Yeşin, Tülay; Department of Mechanical Engineering (2005)
A combined cycle gas/steam power plant combines a gas turbine (topping cycle) with a steam power plant (bottoming cycle) through the use of a heat recovery steam generator. It uses the hot exhaust of the gas turbine to produce steam which is used to generate additional power in the steam power plant. The aim of this study is to establish the different bottoming cycle performances in terms of the main parameters of heat recovery steam generator and steam cycle for a chosen gas turbine cycle. First of all; fo...
Enhancement of flotation performance of oil shale cleaning by ultrasonic treatment
Altun, Naci Emre; Hicyilmaz, Cahit (Elsevier BV, 2009-04-16)
In this study, it was attempted to enhance the performance of flotation cleaning of oil shales by use of ultrasound. The use of an excitation effect through ultrasonication was investigated towards inorganic particles that remain clogged in pores/voids or attached as surface coatings. Ultrasonic treatment was applied prior to flotation at different ultrasonic power levels and for different ultrasonication periods. Ultrasonic treatment proved to be useful in improving the extent of ash rejection. After ultra...
