H2 Storage at Ambient Temperature using Cu(I)-SSZ-39
İpek Torun, Bahar; Üner, Deniz (2019-06-23)
Hydrogen storage capacities of transition metal cation exchanged zeolites; i.e., Cu(I)-SSZ-39 and Cu(I)-US-Y, were tested at temperatures between 279 K and 304 K and at pressures up to 1 bar. The hydrogen capacity values were higher for Cu(I)-exchanged SSZ-39, which has smaller pore openings and a cage when compared to a large-pore zeolite: Cu(I)-US-Y. Hydrogen capacities at 1 bar per gram of zeolites were found as 83 μmol g-1 (0.02 wt. %) at 278 K and 60 μmol g-1 at 296 K on Cu(I)-SSZ-39 and 35 μmol g-1 (0...

H₂/H∞ mixed robust controller synthesis for a fin actuation system
Ölçer, Tuncay Uğurlu; Balkan, Raif Tuna; Platin, Bülent Emre; Department of Mechanical Engineering (2013)
In fin actuation systems, the performance of classical linear control systems is not satisfactory due to uncertainty of the system parameters and disturbances of the working medium. For this reason, sliding mode, H2 or H∞ robust controllers are widely used in literature for such systems. However, use of such controllers results in very conservative system responses. Based on this fact, in this thesis, development of a more effective robust controller is aimed via integration of the optimum properties of the...
HF and DFT studies and vibrational spectra of 1,2-bis(2-pyridyl) ethylene and its zinc (II) halide complexes
Ozhamam, Z.; Yurdakul, Murat Hayrettin; Yurdakul, S. (2007-03-11)
Ab initio restricted Hartree-Fock and density function theory calculations using BLYP, B3LYP and B3PW91 functionals were carried out to study molecular structure and vibrational spectrum of 1,2-bis(2-pyridyl)ethylene (which is abbreviated as bpe). Comparison of calculated and experimental results indicates the density functional B3LYP and BLYP/6-311G* methods are more accurate in predicting fundamental vibrational frequencies than the scaled other approaches. On the basis of calculated results, assignment o...

A novel watermarking method is presented in which the data embedded into a 3D model is extracted from an arbitrary 2D view by using a perspective projective invariant. The data is embedded into 3D positions of selected interest points on a 3D mesh. Determining the interest point modification vectors for ensuring watermark detection constitutes an important part of the proposed method. Different watermark embedding schemes based on optimization of the watermark function are implemented and evaluated. Another...
