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 ...
Code-index modulation aided quadrature spatial modulation for high-rate MIMO systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2019)
In this correspondence paper, a novel code-index modulation (CIM) aided quadrature spatial modulation (QSM) scheme, called CIM-QSM, is proposed for highly spectrum and energy efficient multiple-input multiple-output (MIMO) ...
Applications of a pnCCD detector coupled to columnar structure CsI(Tl) scintillator system in ultra high energy X-ray Laue diffraction
(Iop Publishing Ltd, 2017)
Most charge coupled devices (CCDs) are made of silicon (Si) with typical active layer thicknesses of several microns. In case of a pnCCD detector the sensitive Si thickness is 450 mu m. However, for silicon based detectors ...
An adaptive block backstepping controller for a quadrotor
(Ieee, 2018)
An adaptive block backstepping controller is proposed to control the position of a quadrotor with uncertain model parameters. The controller design procedure is provided considering the stability of six blocks involving ...
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 ...
Drilling process and resulting surface properties of Inconel 718 alloy fabricated by selective laser melting additive manufacturing
(Elsevier B.V., 2020)
One of the challenges is to produce holes with expected dimensional accuracy in metal additive manufacturing. Although post-processing is usually carried out for the additively manufactured components but improving the ...
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 ...
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 ...
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 ...
