The energy dissipation capacity of reinforced concrete (RC) columns is investigated under inelastic cyclic displacements. Experimental data are obtained from 20 column specimens tested under constant-amplitude displacement cycles and from three column specimens tested under variable-amplitude displacement cycles. The effect of failure mode, displacement ductility, material properties, and detailing on the energy dissipation capacity of columns is investigated first under constant-amplitude loading. A simple model is developed for predicting the cyclic energy dissipation capacity under constant-amplitude inelastic displacement cycles. Then, an analytical procedure is introduced for estimating the energy dissipation under variable-amplitude displacement cycles by using the energy dissipation capacity, under constant-amplitude displacements. The proposed procedure is verified with the test results.

Adsorption and dissociation of PH3 on SiGe(100) (2x1) surface Turkmenoglu, Mustafa; Katırcıoğlu, Şenay (World Scientific Pub Co Pte Lt, 2008-06-01) The most stable structures for the adsorption and dissociation of phosphine (PH3) on SiGe(100) (2 x 1) surface have been investigated by relative total energy calculations based on density functional theory. According to the optimization calculations, PH3 is adsorbed on the Si (down) and Ge (down) site of the Ge-Si and Ge-Ge dimers on SiGe surface, respectively. The PH2 and H products have been found to be thermodynamically favored in the dissociation path of PH3 on SiGe surface when the system is thermally...
Quantum chemical calculations of warfarin sodium, warfarin and its metabolites Tekin, Emine Deniz (Calisir); ERKOÇ, Figen; YILDIZ, İLKAY; Erkoç, Şakir (2008-07-01) The structural, vibrational and electronic properties of warfarin sodium, warfarin and its metabolites have been investigated theoretically by performing the molecular mechanics (MM+ force field), the semi-empirical self-consistent-field molecular-orbital (AM1), and density functional theory calculations. The geometry of the molecules have been optimized, the vibrational dynamics and the electronic properties of the molecules have been calculated in their ground state in gas phase.
Energy Conversion Efficiency of Single-Phase Transformerless PV Inverters Özkan, Ziya; Hava, Ahmet Masum (2013-11-30) In grid-connected photovoltaic (PV) applications, power semiconductor energy conversion efficiency of PV inverters is one of the major figures of merits to evaluate and compare these systems as the payback ratio of the overall system is tightly related to the energy conversion efficiency and as semiconductor losses comprise the majority of energy losses. In order to wisely choose the PV inverter topology and associated semiconductors, analytic evaluation of semiconductor losses of topologies is required. Fu...
ELECTRICAL RESISTIVITIES OF LIQUID AL-MG AND AL-CU ALLOYS KHAJIL, TMA; Tomak, Mehmet (1989-05-01) The electrical resistivity of liquid Al−Mg and Al−Cu alloys is calculated using both the Faber-Ziman and «2k F» scattering theories. The partial structure factors are described by the hard-sphere system. The calculated resistivity values are in qualitative agreement with available experimental data.
Thermal stability of benzorods: Molecular-dynamics simulations Malcıoğlu, Osman Barış (Elsevier BV, 2005-12-01) Thermal stability of benzorods 2C6-20C6, which are obtained by stacking n (n=2-20) dehydrogenated benzene, have been investigated by molecular-dynamics simulations. It has been found that these structures assume a geometrical form depending on the number of dehydrogenated benzene layers, and they are stable under heat treatment up to elevated temperatures with a dependence on length.
