A lyapunov based model reference adaptive control of a quadrotor
Akgün, Onur; Subaşı, Evren; Türker, Türker (Ieee, 2017)Model reference adaptive controller is proposed to control the position of a quadrotor with uncertain model parameters. The controller design procedure is provided considering position and attitude dynamics as outer and ... -
Micro and nano damage observations of martensitic and austenitic open cell cast foams
Kaya, Ali Can; Fromert, Jan; Jost, Norbert; Fleck, Claudia (Elsevier Science, 2022)In current study a detailed investigation of the 304 austenitic and 420 martensitic foams damage has been carried out at all hierarchical levels. In-situ compression testing of foams and microtensile testing of single ... -
Modeling of complex gray cast iron open-cell foams revealing insights on failure and deformation on different hierarchical length-scales
Kaya, Ali Can; Zaslansky, Paul; Fleck, Claudia (Wiley-VCH, 2021)Open-cell gray cast iron foams are a class of porous materials of increasing interest, with great potential to be used in energy damping applications and for sound isolation. We created finite element (FE) models from 3D ... -
A new spectroscopic imager for X-rays from 0.5 keV to 150 keV combining a pnCCD and a columnar CsI(Tl) scintillator
Schlosser, Dieter Michael; Hartmann, Robert; Kalok, D.; Bechteler, A.; Abboud, Ali; Shokr, Mohammad Mahdi; Strüeder, Lothar; Çonka Yıldız, Tuba (Iop Publishing Ltd, 2017)By combining a low noise fully depleted pnCCD detector with a columnar CsI(Tl) scintillator an energy dispersive spatial resolving detector can be realized with a high quantum efficiency in the range from below 0.5 keV to ... -
Performance analysis of Hexagonal QAM constellations on quadrature spatial modulation with perfect and imperfect channel estimation
Çögen, Fatih; Aydın, Erdoğan (Elsevier, 2021)In this study, the quadrature spatial modulation (QSM) technique, which is a rational multiple-input multiple-output (MIMO) transmission technique and frequently encountered in recent studies in the literature, and the ... -
Single steel strut mechanical testing: challenges and future research directions
Kaya, Ali Can; Zaslansky, Paul; Fischer, Sebastian; Fleck, Claudia (Taylor & Francis Ltd, 2019)Open-cell stainless steel foams, composed of hollow struts, are excellent candidates for energy absorption and thermo-mechanical applications. The basic mechanical element responsible for the function of these foams is the ... -
Single-shot full strain tensor determination with microbeam X-ray Laue diffraction and a two-imensional energy-dispersive detector
Abboud, Ali; Kirchlechner, C.; Keckes, J.; Çonka Yıldız, Tuba; Send, S.; Micha, J. S.; Pietsch, U. (Int Union Crystallography, 2017)The full strain and stress tensor determination in a triaxially stressed single crystal using X-ray diffraction requires a series of lattice spacing measurements at different crystal orientations. This can be achieved using ... -
