Theoretical investigation of block copolymerization of tetrahydrofuran and pyrrole
Yurtsever, M; Toppare, Levent Kamil (1999-09-01)
In this work, semi-empirical quantum mechanical techniques were employed in order to discuss the feasibility of the copolymerization reaction between tetrahydrofuran and pyrrole starting from two different macromonomers in which polytetrahydrofuran has a pyrrole moiety at one or both ends.
Flow visualization and determination of temperature distribution in inclined channels
Sağlamcı, Abdülaziz Mehmet; Bayer, Özgür; Department of Mechanical Engineering (2018)
Subway transportation systems play an important role in human life in this century. Millions of people make use of subway transportation every day in metropolises. In subways, there is a very crucial situation "case of fire and smoke generation" that must be prevented. In subway areas, it is known that stairs are used to connect the ground with the subway area, metro stations in other words. Stairs have an angle with the ground horizontal called as tilt angle. The most important case of smoke movement in ca...
Numerical solution of solidification in a square prism using an algebraic grid generation technique
Dursunkaya, Zafer (Springer Science and Business Media LLC, 2003-12-1)
The solidification of an infinitely long square prism was analyzed numerically. A front fixing technique along with an algebraic grid generation scheme was used, where the finite difference form of the energy equation is solved for the temperature distribution in the solid phase and the solid-liquid interface energy balance is integrated for the new position of the moving solidification front. Results are given for the moving solidification boundary with a circular phase change interface. An algebraic grid ...
Effective gauge theories from fuzzy extra dimensions
Ünal, Gönül; Kürkcüoğlu, Seçkin; Department of Physics (2016)
In this thesis, we investigate the formulation and various aspects of gauge theories with fuzzy extra dimensions. In SU (N ) gauge theories coupled to a suitable number of adjoint scalar fields, we determine a family of fuzzy vacuum configurations dynamically emerging after the spontaneously symmetry breaking of the gauge symmetry. The emergent models are conjectured to be effective U (n) (n < N ) gauge theories with fuzzy extra dimensions. Making use of the equivariant parametrization technique and focusin...
Complex monopoles in the Georgi-Glashow-Chern-Simons model
Tekin, Bayram; Hosotani, Y (1999-02-01)
We investigate the three-dimensional Georgi-Glashow model with a Chern-Simons term. We find that there exist complex monopole solutions of finite action. They dominate the path integral and disorder the Higgs vacuum, but electric charges are not confined. Subtleties in the gauge-fixing procedure in the path integral and issues related to Gribov copies are noted. (C) 1999 Elsevier Science B.V.
