Numerical and experimantal analysis of flapping motion
Sarıgöl, Ebru; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2007)
The aerodynamics of two-dimensional and three-dimensional flapping motion in hover is analyzed in incompressible, laminar flow at low Reynolds number regime. The aim of this study is to understand the physics and the underlying mechanisms of the flapping motion using both numerical tools (Direct Numerical Simulation) and experimental tools (Particle Image Velocimetry PIV technique). Numerical analyses cover both two-dimensional and three-dimensional configurations for different parameters using two differen...
Aerodynamic parameter estimation using flight test data
Kutluay, Ümit; Platin, Bülent Emre; Mahmutyazıcıoğlu, Gökmen; Department of Mechanical Engineering (2011)
This doctoral study aims to develop a methodology for use in determining aerodynamic models and parameters from actual flight test data for different types of autonomous flight vehicles. The stepwise regression method and equation error method are utilized for the aerodynamic model identification and parameter estimation. A closed loop aerodynamic parameter estimation approach is also applied in this study which can be used to fine tune the model parameters. Genetic algorithm is used as the optimization ker...

Purification and characterization of cytoplasmic and proteasome associated chymotrypsin-like proteases from Thermoplasma volcanium
Özdemir, F. İnci; Kocabıyık, Semra; Department of Biology (2003)
In this study, two novel cytoplasmic serine proteases were isolated and characterized from thermophilic archaea Thermoplasma volcanium. The first protease was purified by ion exchange and affinity chromatographies and identified as a chymotrypsin-like serine protease mainly based on its substrate profile and inhibition pattern. The presence of protease activity was analyzed by gelatin zymography which was detected as a single band (35 kDa). Optimum temperature was found to be 60oC for azocasein hydrolysis a...
Investigation over a national meteorological fire danger approach for Turkey with geographic information systems
Yamak, Çağatay; Akyürek, Sevda Zuhal; Department of Geodetic and Geographical Information Technologies (2006)
The aim of this study was to investigate Meteorological Fire Danger Indices for Turkey. A number of internationally implemented fire danger indices were calculated with Fire Danger Processing software and their performances were tested with Mandallaz and Ye’s Performance Score Method. As a result, among other meteorological fire danger indices that have been applied by several fire fighting administrations and services, the U.S. National Fire Danger Rating System, Mc.Arthur’s Fuel Moisture Model and Forest ...
