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
