Cooperative quadrature spatial modulation with Euclidean distance and capacity optimized antenna selection
(Wiley, 2021)
In this study, new cooperative-quadrature spatial modulation techniques based on Euclidean distance and capacity optimized antenna selection techniques (EDAS-CQSM and COAS-CQSM) are proposed for cooperative communication ...
In situ shear behavior of open-cell austenitic 316L steel foams
(Elsevier Science Sa, 2020)
Foam cores in crash boxes are subjected to large shear forces during crash situations. Here, the failure behavior of 316L open-cell stainless steel foams under shearing conditions was investigated. A custom-made grip system ...
Influence of heat treatment temperature on the microstructural, mechanical, and wear behavior of 316L stainless steel fabricated by laser powder bed additive manufacturing
(Springer London Ltd, 2020)
A metal component fabricated by additive manufacturing (AM) is generally required to be heat treated to enhance microstructural and mechanical aspects. This present study aims to contribute to the literature in understanding ...
Investigation of temperature effect on the electrical properties of MWCNTs/epoxy nanocomposites by electrochemical impedance spectroscopy
(Taylor & Francis Ltd, 2020)
This study investigates the impact of the temperature exposure on the electrical properties of the multi-walled carbon nanotubes (MWCNTs)/epoxy based nanocomposites for the temperature range from 20 degrees C to 80 degrees ...
Foams of gray cast iron as efficient energy absorption structures: a feasibility study
(Wiley-V C H Verlag Gmbh, 2019)
Gray cast iron foams, were produced using a reticulated polyurethane by using a modified investment casting process. To evaluate the attributes of the produced micro-geometries, foam segments and single struts are investigated ...
Electrical impedance analysis of carbon nanotube/epoxy nanocomposite-based piezoresistive strain sensors under uniaxial cyclic static tensile loading
(Sage Publications Ltd, 2020)
Carbon nanotubes-based nanocomposites have gained a great amount of attraction and play a key role in the realization of strain sensors owing to their remarkable physical properties. In this study, the piezoresistivity of ...
Micro and nano damage observations of martensitic and austenitic open cell cast foams
(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 ...
Differential chaos shift keying assisted media-based modulation
(İstanbul Üniversitesi, 2021)
This study proposes a new energy-efficient and high data-rated communication technique by combining media-based modulation (MBM) and differential chaos shift keying technique (DCSK), called DCSK–MBM. The MBM technique, ...
Strain hardening reduces energy absorption efficiency of austenitic stainless steel foams while porosity does not
(Elsevier Sci Ltd, 2018)
Strain hardening significantly affects the mechanical function of steel foams. We compare hardening and failure of two commercially available austenitic stainless steel foams (316L and 310) spanning strut porosities of 9.4 ...
Direct and indirect signal detection of 122 keV photons with a novel detector combining a pnCCD and a CsI(T1) scintillator
(Elsevier, 2016)
By combining a low noise fully depleted pnCCD detector with a CsI(TI) scintillator, an energy-dispersive area detector can be realized with a high quantum efficiency (QE) in the range from below 1 keV to above 100 keV. In ...
