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 ...
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 ...
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 ...
Effects of the cell number and anisotropy in the open cell metal foams on the energy absorption efficiency
(Pamukkale Univ, 2020)
By means of cellular structure, open cell metal foams can be used as a light-weight material, and they can absorb impact energy effectively. In this study, effects of cell number and anisotropy in 30 and 45 ppi (pores per ...
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 ...
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, ...
Heat treatment temperature-induced microstructure, microhardness and wear resistance of inconel 718 produced by selective laser melting additive manufacturing
(Elsevier GmbH, 2021)
Additive manufacturing (AM) has been becoming more widespread and its usage area has been increasing in various industries. However, the mechanical and microstructural properties of the metal parts fabricated by additive ...
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 ...
