Optimum geometry design of geodesic domes using harmony search algorithm
Saka, M. P. (2007-12-01)
The optimum geometry design of geodesic domes presents difficulty due to the fact that the height of the dome keeps on changing during the design process. This in turn makes it necessary to automate the computation of the coordinates of joints in the dome when the height of crown changes. The algorithm presented in this study carries out the optimum geometry design of single layer geodesic domes. It treats the height of the crown as design variable in addition to the cross-sectional designations of members....
Saluting the sun under the shadow of neoliberalism: an ethnographic study of yoga teacher training course attendees and yoga teachers
Aydıner Juchat, Pelin; Karababa, Eminegül; Department of Social Anthropology (2019)
This study is based on a six months ethnographic research conducted in Ankara with yoga trainers and yoga teacher training course attendees. Individuals subject to the study were dreaming of creating an alternative space, adopting a new profession and a new way of life by becoming professional yoga teachers. While the neoliberal dynamics that lead to the need for such an escape were questioned, the commercialization and institutionalization of yoga and yoga teacher training programs were also analyzed. This...
Optimum design of 3-d irregular steel frames using ant colony optimization and harmony search algorithms
Aydoğdu, İbrahim; Saka, Mehmet Polat; Tokdemir, Turgut; Department of Engineering Sciences (2010)
Steel space frames having irregular shapes when subjected to lateral loads caused by wind or earthquakes undergo twisting as a result of their unsymmetrical topology. As a result, torsional moment comes out which is required to be resisted by the three dimensional frame system. The members of such frame are generally made out of steel I sections which are thin walled open sections. The simple beam theory is not adequate to predict behavior of such thin-walled sections under torsional moments due to the fact...
Optimum topology design of various geometrically nonlinear latticed domes using improved harmony search method
Carbas, Serdar; Saka, Mehmet P. (2012-03-01)
Domes are elegant and economical structures used in covering large areas. They are built in various forms. According to their form, they are given special names such as lamella, network, and geodesic domes. In this paper, optimum topological design algorithm is presented that determines the optimum number of rings, the optimum height of crown and tubular section designations for the member groups of these domes. The design algorithm developed has a routine that generates the data required for the geometry o...
Electromagnetic simulation and optimization of an electromagnetic launcher
Ceylan, Doğa; Keysan, Ozan; Department of Electrical and Electronics Engineering (2018)
Electromagnetic launcher (EML) is an electromagnetic accelerator which uses electrical pulse power instead of conventional gunpowder. A large amount of electric current in the pulse waveform flows in the rails and armature. This current creates large magnetic field between rails. As a result of Lorentz force, armature and projectile accelerate. In this study, finite element (FE) model of an EML which includes both pulsed power supply (PPS) circuits with 2~MJ total electrical energy and barrel with 3~m lengt...
