Dynamic sidelobe multiplexing in beamspace MIMO systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Recent studies on multiplexing concept over beamspace multiple-input-multiple-output (MIMO) can reduce the need for using phase shifters while keeping the directivity performance at similar levels. Thus, beamspace MIMO ...
A spatially adaptive antenna array for mm-wave wireless channel control with microfluidics based reconfiguration
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Spatially adaptive antenna array (SAA) is an electronically scanned antenna array with capability of changing its physical location. This new capability allows SAA to control the wireless channel environment to increase ...
OFDM with hybrid number and index modulation
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division ...
User pairing and power allocation strategies for 3D VLC-NOMA systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
In this letter, we propose two novel, yet efficient, user pairing schemes for non-orthogonal multiple access (NOMA) in 3D visible light communication (VLC). Our analysis is carried out assuming different heights for the ...
A hybrid deep model using deep learning and dense optical flow approaches for human activity recognition
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
Human activity recognition is a challenging problem with many applications including visual surveillance, human-computer interactions, autonomous driving and entertainment. In this study, we propose a hybrid deep model to ...
Predicting path loss distribution of an area from satellite ımages using deep learning
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
Path loss prediction is essential for network planning in any wireless communication system. For cellular networks, it is usually achieved through extensive received signal power measurements in the target area. When the ...
Fabrication of nickel manganese cobalt oxide (NMCO) anodes for lithium-ion batteries via hydrothermal process
(Springer, 2020)
Nickel manganese cobalt oxide (NMCO) powders have been fabricated by hydrothermal method followed by a calcination. The present work reports for the first time in the open literature, the effects of ammonium fluoride (NH4F) ...
Cytotoxicity of standardized curcuminoids mixture against epithelial ovarian cancer cell line SKOV-3
(MDPI, 2020)
Herbal medicine has been in use for centuries for a wide variety of ailments; however, the efficacy of its therapeutic agents in modern medicine is currently being studied. Curcuminoids are an example of natural agents, ...
Mathematical modelling of sound transmission loss performances of different coloured surfaces coated with polyurethane-based paint
(Taylor and Francis Ltd., 2020)
The aim of this study is to investigate the effect of morphologies and the structure of polyurethane-based coatings created by different colour pigments, on sound transmission loss properties. To achieve this goal, coatings ...
Temperature and precipitation risk assessment under climate change effect in northeast algeria
(Springer International Publishing AG, 2020)
Climate change impacts on social, economic, industrial, agricultural, and water resource systems tend to increase incrementally with each passing day. Therefore, it is necessary to plan to control its effects, especially ...
