Cloud-Edge Suppression for Visual Outdoor Navigation

open access: yesRobotics, 2017
Outdoor environments pose multiple challenges for the visual navigation of robots, like changing illumination conditions, seasonal changes, dynamic environments and non-planar terrain. Illumination changes are mostly caused by the movement of the Sun and

La videoproiezione architetturale

open access: yesDisegnare con, 2011
Trasfigurare un edificio, seppure temporaneamente, comporta una serie di responsabilità: l'edificio  non è semplicisticamente uno schermo su cui proiettare immagini, si trasforma invece nel luogo dove l'idea architettonica viene portata ad un livello ...

Bending torsion in Γ-shaped rigid and warping hinge joints

open access: yesMagazine of Civil Engineering, 2020
This paper investigates the effect of bending torsion which is the cross-sectional warping of thin-walled rods at plane frame joints in the framework of the “semi-shear” theory of V.I. Slivker.

View synthesis with sparse light field for 6DoF immersive video

open access: yesETRI Journal, 2022
Virtual view synthesis, which generates novel views similar to the characteristics of actually acquired images, is an essential technical component for delivering an immersive video with realistic binocular disparity and smooth motion parallax.

Accounting of cross-sectional deformation of the contour in the calculation of thin-walled rods

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2014
One of the main hypotheses in the calculation of thin-walled rods theory is the assumption that there is no deformation of the contour of the cross section.

Estimation of geoacoustic parameters and source range using airgun sounds in the East Siberian Sea, Arctic Ocean

open access: yesFrontiers in Marine Science
Dispersion is a representative property of low-frequency sound propagation over long distances in shallow-water waveguides, making dispersion curves valuable for geoacoustic inversion. This study focuses on estimating the geoacoustic parameters using the

Effect of Annealing Time of GaN Buffer Layer on Curvature and Wavelength Uniformity of Epitaxial Wafer

open access: yesCondensed Matter
In this study, the curvature changes of an unintentionally doped GaN end and third quantum well were observed in situ when the annealing times of a GaN buffer layer were 40 s, 50 s and 55 s, respectively.

Putting the Warp into Warp Drive

open access: yes, 2008
Over the last decade, there has been a respectable level of scientific interest regarding the concept of a warp drive. This is a hypothetical propulsion device that could theoretically circumvent the traditional limitations of special relativity which restricts spacecraft to sub-light velocities. Any breakthrough in this field would revolutionize space
