Faking Signals to Fool Deep Neural Networks in AMC via Few Data Points
IEEE Access, 2021 The recent years has witnessed a rapid development of Deep Learning (DL) based Automation Modulation Classification (AMC) methods, which has proved to outperform traditional classification approaches. In order to disturb the deep neural networks for AMC,

Safety analysis of rotors in ground effect [PDF]
Aerospace Science and Technology, 2021 In this work, computational fluid dynamics was used to support safety analyses of rotors operating in ground effect. Initially, the research focused on the evaluation and prediction of the outwash generated by a hovering micro-rotor, and time-averaged outflow velocities were compared with experimental results. Then, using scaling factors, the simulated

The Ground Effect in Anguilliform Swimming [PDF]
Biomimetics, 2020 Some anguilliform swimmers such as eels and lampreys swim near the ground, which has been hypothesized to have hydrodynamic benefits. To investigate whether swimming near ground has hydrodynamics benefits, two large-eddy simulations of a self-propelled anguilliform swimmer are carried out—one swimming far away from the ground (free swimming) and the ...

Novel Methodology for Sizing a Single U-Tube Ground Heat Exchanger Useful at the Early Design Stage
Buildings, 2021 Renewable energy system (RES) is an environmentally friendly source of energy. A suitable design of RES is crucial to implement an energy-efficient building such as a zero energy building (ZEB).

Grounding as a Side‐Effect of Grounding [PDF]
Topics in Cognitive Science, 2018 AbstractIn relation to semantics, “grounding” has (at least) two relevant meanings. “Symbol grounding” is the process of connecting symbols (e.g., words) to perception and the world. “Communicative grounding” is the process of interactively adding to common ground in dialog. Strategies for grounding in human communication include, crucially, strategies

Toward Hybrid CAA with Ground Effects [PDF]
International Journal of Aeroacoustics, 2014 CAA based on the Linearised Euler Equations (LEE) is applied to propagate aerodynamic sound over an extended distance including ground effects. The LEE are coupled to data from an LES via an acoustic analogy to follow-up the sound from the source to the extended far field: the complete chain is illustrated on the sound generated by a cylinder in a M ...
