AUTOMATIC DETECTION AND CHARACTERISATION OF POWER LINES AND THEIR SURROUNDINGS USING LIDAR DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Light Detection and Ranging (LiDAR) is nowadays one of the most used tools to obtain geospatial data. In this paper, a method to detect and characterise power lines of both high and low voltage and their surroundings from 3D LiDAR point clouds ...

Screw sense excess and reversals of helical polymers in solution

open access: yesNature Communications, 2023
Reversals are structural motifs found in helical polymers that are difficult to determine experimentally. Here, the authors turn to photochemical electrocyclization as a tool to establish their presence and estimate excess screw sense in solution.

Biomimetic cell-derived nanocarriers in cancer research

open access: yesJournal of Nanobiotechnology, 2022
Nanoparticles have now long demonstrated capabilities that make them attractive to use in biology and medicine. Some of them, such as lipid nanoparticles (SARS-CoV-2 vaccines) or metallic nanoparticles (contrast agents) are already approved for their use

Les interprétations sémantiques des groupes nominaux sans déterminant en ancien-haut-allemand

open access: yesCorela, 2023
In modern German, singular noun phrases without any actualizer (type [ØN]sg) encode a non-discrete and undefined aim. In old high German, the marking of nominal categories is the object of current development, and the interpretation of a noun phrase ...

Benchmarking of FinFET, Nanosheet, and Nanowire FET Architectures for Future Technology Nodes

open access: yesIEEE Access, 2020
Nanosheet (NS) and nanowire (NW) FET architectures scaled to a gate length (LG) of 16 nm and below are benchmarked against equivalent FinFETs. The device performance is predicted using a 3D finite element drift-diffusion/Monte Carlo simulation toolbox ...

Four-Dimensional Gait Surfaces for a Tilt-Rotor—Two Color Map Theorem

open access: yesDrones, 2022
This article presents the four-dimensional surfaces that guide the gait plan for a tilt-rotor. The previous gaits analyzed in the tilt-rotor research are inspired by animals; no theoretical base backs the robustness of these gaits.

Highly Dispersive Optical Solitons with Four Forms of Self-Phase Modulation

open access: yesUniverse, 2023
This paper implements the enhanced Kudryashov approach to retrieve highly dispersive optical solitons and study it with four nonlinear forms. These are the power law, generalized quadratic-cubic law, triple-power law, and the generalized non-local law ...
