Characterization of a Double Mesospheric Bore Over Europe [PDF]

open access: yes, 2017
Observations of a pair of mesospheric bore disturbances that propagated through the nighttime mesosphere over Europe are presented. The observations were made at the Padua Observatory, Asiago (45.9\ub0N, 11.5\ub0E), by the Boston University all-sky ...

Simulation of undular bores evolution with damping [PDF]

open access: yes, 2017
Propagation of undular bores with damping is considered in the framework of perturbed extended Korteweg-de Vries (peKdV) equation. Two types of damping terms for the peKdV equation, namely linear and Chezy frictional terms, which describe the turbulent ...

Mesospheric bores at southern midlatitudes observed by ISS-IMAP/VISI: a first report of an undulating wave front [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Large-scale spatial structures of mesospheric bores were observed by the Visible and near-Infrared Spectral Imager (VISI) of the ISS-IMAP mission (Ionosphere, Mesosphere, upper Atmosphere and Plasmasphere mapping mission from the International Space ...

Against pleasure: the art that bores us

open access: yesANIAV, 2021
The traditional concept of art is closely related to beauty and also to aesthetic pleasure. However, the emergence of avant‐garde and contemporary art has subverted that imagination.

Transcritical flow of a stratified fluid over topography: analysis of the forced Gardner equation [PDF]

open access: yes, 2013
Transcritical flow of a stratified fluid past a broad localised topographic obstacle is studied analytically in the framework of the forced extended Korteweg--de Vries (eKdV), or Gardner, equation.

Influence of LPBF Parameters and Strategies on Fine Machining of Pre-Built Bores

open access: yesJournal of Machine Engineering, 2021
Additive manufacturing changes the classical possibilities of production. However, post-processing is usually unavoidable for these components to achieve functional performance.

Consideration of the Mechanisms for Tidal Bore Formation in an Idealized Planform Geometry [PDF]

open access: yes, 2018
A tidal bore is a positive wave traveling upstream along the estuary of a river, generated by a relatively rapid rise of the tide, often enhanced by the funneling shape of the estuary.

Cavitation in Single-Vane Sewage Pumps

open access: yesInternational Journal of Rotating Machinery, 2008
Chair fluidsystemdynamics at TU Berlin investigated the cavitation behavior of a full-size single-vane sewage pump. Single-vane pumps are used for raw sewage with high content of dirt and sediments in larger sewage pumping stations.

Experimental Investigations on Temperature and Frictional Behaviors of Textured Journal Bearings

open access: yesTribology in Industry, 2022
Experimental work provides a greater insight into the performances of journal bearings under actual operating conditions. Moreover, experimental findings also provide a platform for validation of numerical model based results and helps to point out ...
