Using OMP and SD algorithms together in mm-Wave mMIMO channel estimation
(Springer London Ltd, 2022)
Lens antenna array is considered as an effective beam selection mechanism in millimeter wave massive multiple input multiple output systems. Efficient channel estimation (CE) algorithms are required to use the advantage ...
Hydroelectric energy potential classification via hypsographical curve concept
(Wiley, 2022)
Human activities are directly related to fossil fuel consumption and cause global warming and climate change effects by emitting greenhouse gas into the lower atmosphere. To reduce and adapt to such effects, renewable ...
Online routing and searching on graphs with blocked edges
(Springer, 2022)
We study routing and searching decisions of a search-and-detection (SDT) team on a road network under online uncertainty setting. Given an undirected edge-weighted bounded graph, a static target is positioned at an unknown ...
Exploiting user diversity in OTFS transmission for beyond 5G wireless systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Orthogonal time frequency space (OTFS) modulation is a recent technology that offers a significant advantage on link reliability due to its strong delay-Doppler resilience. In classical cellular technology, overall system ...
Explainable artificial intelligence through graph theory by generalized social network analysis-based classifier
(Nature Portfolio, 2022)
We propose a new type of supervised visual machine learning classifier, GSNAc, based on graph theory and social network analysis techniques. In a previous study, we employed social network analysis techniques and introduced ...
Free vibration of axially FG curved beam on orthotropic Pasternak foundation via mixed FEM
(Springer Science and Business Media Deutschland GmbH, 2022)
The main objective of this study is to present an accurate and consistent original formulation to describe the interaction between planar straight/curved beam structure and orthotropic foundation by highlighting the ...
Successive probable maximum precipitation (SPMP) methodology and applications
(Springer Wien, 2022)
PMP has two different estimation methods, namely statistical and hydro-meteorological approaches. The statistical method is based on the calculation of frequency factor (FF) by taking into account the arithmetic mean and ...
Channel randomness-based adaptive cyclic prefix selection for secure OFDM system
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
A novel method for cyclic prefix (CP) adaptation based on wireless channel randomness is proposed for orthogonal frequency-division multiplexing (OFDM) systems in urban areas. Especially, a quantization algorithm and an ...
Microwave-promoted continuous flow synthesis of thermoplastic polyurethane-silver nanocomposites and their antimicrobial performance
(Royal Society of Chemistry, 2022)
Thermoplastic polyurethane-silver nanocomposites (PU-Ag NCs) have considerable potential in many medical applications due to their superior mechanical and antimicrobial properties. Herein, a microwave-promoted flow system ...
Characterization and biological evaluation of crataegus azarolus fruit polysaccharides
(Elsevier B.V., 2022)
The polysaccharide obtained from Crataegus azarolus fruit, by water extraction followed by ethanol precipitation and fractionation using copper complex, shows physiological activities: prebiotic and antioxidant. The total ...
