Adaptive Neuro-Filtering Based Visual Servo Control of a Robotic Manipulator

open access: yesIEEE Access, 2019
This paper focuses on the solutions to flexibly regulate robotic by vision. A new visual servoing technique based on the Kalman filtering (KF) combined neural network (NN) is developed, which need not have any calibration parameters of robotic system ...

DIFFERENT SCALES OF URBAN TRAFFIC NOISE PREDICTION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Noise pollution is an important problem. Places around the road or railway corridor can get serious noise hazards in the outdoor environment. The problem of noise is dynamic and varies from one location to another.

High Dynamic Range Mapping for Synthetic Aperture Radar Images

open access: yesTelfor Journal, 2018
Luminance compression is often performed for high dynamic range images (still images and videos). A nonlinear tone mapping is applied for the compression in order to reproduce high dynamic range images using devices with a more limited (low) dynamic ...

On the Dynamical Behavior of Solitary Waves for Coupled Stochastic Korteweg–De Vries Equations

open access: yesMathematics, 2023
In this paper, we take into account the coupled stochastic Korteweg–De Vries (CSKdV) equations in the Itô sense. Using the mapping method, new trigonometric, rational, hyperbolic, and elliptic stochastic solutions are obtained.

Description of Anomalous Noise Events for Reliable Dynamic Traffic Noise Mapping in Real-Life Urban and Suburban Soundscapes

open access: yesApplied Sciences, 2017
Traffic noise is one of the main pollutants in urban and suburban areas. European authorities have driven several initiatives to study, prevent and reduce the effects of exposure of population to traffic.
