Use of Lawesson's reagent in organic syntheses


Investigation of Stockbridge dampers for vibration control of overhead transmission lines
Kasap, Hüseyin; Özgen, Gökhan Osman; Department of Mechanical Engineering (2012)
This thesis aims to examine the performance of Stockbridge dampers used to suppress aeolian vibrations on overhead transmission lines arising from the wind. In this respect, a computer program, based on the Energy Balance Method, is developed using MATLAB. The developed computer program has also a graphical user interface (GUI), which allows the program to interactively simulate Stockbridge damper performance for vibration control of overhead transmission lines. Field tests results obtained from literature ...
Utilization of neural networks for simulation of vehicle induced flow in tunnel systems
Koç, Gencer; Albayrak, Kahraman; Sert, Cüneyt; Department of Mechanical Engineering (2012)
Air velocities induced by underground vehicles in complex metro systems are obtained using artificial neural networks. Complex tunnel shaft-systems with any number of tunnels and shafts and with most of the practically possible geometries encountered in underground structures can be simulated with the proposed method. A single neural network, of type feed-forward back propagation, with a single hidden layer is trained for modelling a single tunnel segment. Train and tunnel parameters that have influence on ...
Synthesis, structural characterization, DFT calculations and Hirshfeld surface analysis of (R)-2-((S)-2((S)(-)hydroxy(ferrocenyl)methyl)aziridin-1yl)butan-1-ol
Sen, Betul; Sevincek, Resul; BEKSULTANOVA, Nurzhan; Doğan, Özdemir (2018-12-05)
The title compound, C17H23FeNO2 (2), has been synthesized and its crystal structure has been determined from single crystal X-ray diffraction study. Crystals are monoclinic, a = 6.3541 (5), b = 10.1934 (5), c = 12.6744 (8) angstrom, beta = 92.898 (6)degrees, space group P2(1), Z = 2. The molecular geometry was also optimized using density functional theory (DFT/B3LYP) method with the 6-311G basis set in ground state. From the optimized geometry of the molecule, geometric parameters (bond lengths, bond angle...
Application of nonlinear unit root tests and threshold autoregressive models
Uysal, Ela; Yıldırım Kasap, Dilem; Department of Economics (2012)
Popularity of nonlinear threshold models and unit root tests has increased after the recent empirical studies concerning the effects of business cycles on macroeconomic data. These studies have shown that an economic variable may react differently in response to downturns and recoveries in a business cycle. Inspiring from empirical results, this thesis investigates dynamics of Turkish key macroeconomic data, namely capacity utilization rate, growth of import and export volume indices, growth of gross domest...

Natural and synthetic borates find widespread use in different industries. Among synthetic borates, the lithium borate compounds, lithium tetraborate (Li2B4O7) and lithium triborate (LiB3O5) are very important due to their thermoluminescence (TL) properties and usage potential in radiational dosimetry. It is possible to define the phenomenon of thermoluminescence (TL) or thermally stimulated luminescence (TSL) in several different ways, the simplest of which is emission of light when an irradiated material ...
