Performance analysis of Hexagonal QAM constellations on quadrature spatial modulation with perfect and imperfect channel estimation
(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 ...
Effects of alumina (Al2O3) addition on the cell structure and mechanical properties of 6061 foams
(Cambridge Univ Press, 2013)
In this study, a powder blend representing 6061 Al-alloy was first mixed with Al2O3 ceramic particles and then foamed by using the powder compact melting method. 6061-Al2O3 foams and control specimens 6061 foams (without ...
Application of a pnCCD for energy-dispersive Lauc diffraction with ultra-hard X-rays
(Int Union Crystallography, 2015)
In this work the spectroscopic performance of a pnCCD detector in the ultra-hard energy range between 40 and 140 keV is tested by means of an energy-dispersive Laue diffraction experiment on a GaAs crystal. About 100 Bragg ...
Microbial peptidyl-prolyl cis/trans isomerases (ppIases): virulence factors and potential alternative drug targets
(Amer Soc Microbiology, 2014)
Initially discovered in the context of immunomodulation, peptidyl-prolyl cis/trans isomerases (PPIases) were soon identified as enzymes catalyzing the rate-limiting protein folding step at peptidyl bonds preceding proline ...
Hybrid paper sheets with improved barrier properties
(Scientific & Technical Research Council Turkey-TUBITAK, 2021)
Hybrid paper sheets were prepared by applying a thin coating layer of cross-linked polydimethylsiloxane (PDMS) and inorganic particles onto Whatman Grade 1 filter paper substrates. Several coatings with different inorganic ...
Hexaazatriphenylene doped carbon nitrides-biomimetic photocatalyst with superior oxidation power
(Elsevier Science Bv, 2017)
Pyrazine rings are a fundamental part of folic acid and flavine - cofactors that participate in natural electron transfer processes. Electron deficient carbon nitrides, more specifically poly(heptazine imides) (PHI), ...
NdFeB Magnets recycling process: an alternative method to produce mixed rare earth oxide from Scrap NdFeB Magnets
(MDPI, 2021)
Neodymium iron boron magnets (NdFeB) play a critical role in various technological applications due to their outstanding magnetic properties, such as high maximum energy product, high remanence and high coercivity. Production ...
Application of machine learning methods for pallet loading problem
(MDPI-Multidisciplinary Digital Publishing Institute, 2021)
Because of continuous competition in the corporate industrial sector, numerous companies are always looking for strategies to ensure timely product delivery to survive against their competitors. For this reason, logistics ...
Sustainability impact of digitization in logistics
(Elsevier Science Bv, 2018)
Today, most enterprises are undergoing a digitization process with the fourth industrial revolution, named industry 4.0. The focus of the digital transformation lies mainly on production, therefore the terms such as "Factory ...
Performance analysis of HQAM based spatial modulation over Nakagami-m Fading Channels
(Institute of Electrical and Electronics Engineers, 2020)
In this study, the performance analysis of the recently proposed Hexagonal Square Amplitude Modulation Spatial Modulation (HQAM-SM) system on Nakagami-m fading channels is presented. Performance analysis was performed ...
