Microphysical particle properties derived from inversion algorithms developed in the framework of EARLINET
(European Geosciences Union, 2015-12-08)We present a summary on the current status of two inversion algorithms that are used in EARLINET for the inversion of data collected with EARLINET multiwavelength Raman lidars. These instruments measure backscatter ... -
Topological embeddings into transformation monoids
(2024-09-01)In this paper we consider the questions of which topological semigroups embed topologically into the full transformation monoid ℕ ℕ or the symmetric inverse monoid I ℕ with their respective canonical Polish semigroup ... -
Finite element analysis of drilling-induced damage responses on FRP hybrid bio/composite laminates
(EDP Sciences, 2024-08-27)Machining/drilling is crucial in the joining process of composites. However, drilling composite materials often leads to hole dimensional inaccuracy, surface roughness and delamination, among others. These drilling-induced ... -
Design and development of a small-scale cement-based 3D printing robot extrusion nozzle
(EDP Sciences, 2024-08-28)Additive manufacturing (AM), also known as three-dimensional (3D) printing, offers great potential to create complex structures layer by layer from computer-aided design (CAD) models. Despite advancements in printable ... -
Numerical Simulation of the Effects of Surface Roughness on Light Scattering by Hexagonal Ice Plates
(2024-09-30)Cirrus clouds have an extensive global coverage and their high altitude means they play a critical role in the atmospheric radiation balance. Hexagonal ice plates and columns are two of the most abundant species present ... -
