Mechanical properties of brass sheets

open access: yesMetalurgija, 2021
Brass is widely used in the machine industry, automotive, shipbuilding, construction, metalworking industries, as well as in the production of fittings. Certain types of brass, despite the almost identical chemical composition and the same form resulting

HF/VHF Radar Sounding of Ice from Manned and Unmanned Airborne Platforms

open access: yesGeosciences, 2018
Ice thickness and bed topography of fast-flowing outlet glaciers are large sources of uncertainty for the current ice sheet models used to predict future contributions to sea-level rise.

Wintertime storage of water in buried supraglacial lakes across the Greenland Ice Sheet [PDF]

open access: yesThe Cryosphere, 2015
Increased surface melt over the Greenland Ice Sheet (GrIS) is now estimated to account for half or more of the ice sheet's total mass loss. Here, we show that some meltwater is stored, over winter, in buried supraglacial lakes. We use airborne radar from

Annual Greenland accumulation rates (2009–2012) from airborne snow radar [PDF]

open access: yesThe Cryosphere, 2016
Contemporary climate warming over the Arctic is accelerating mass loss from the Greenland Ice Sheet through increasing surface melt, emphasizing the need to closely monitor its surface mass balance in order to improve sea-level rise predictions.

Crystal structure of 1,3-dihydroxy-2-(hydroxymethyl)propan-2-aminium 2-(4-isobutylphenyl)propanoate: a simple organic salt of racemic ibuprofen

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
In the title organic salt of ibuprofen with trometamol, C4H12NO3+·C13H17O2−, the carboxylic acid group of ibuprofen has transferred its proton to the amino N atom of trometamol. In the crystal, the trometamol cations are linked via N—H...O hydrogen bonds,

A Mobile, Multichannel, UWB Radar for Potential Ice Core Drill Site Identification in East Antarctica: Development and First Results

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
We developed a high-performance, multichannel, ultra-wideband radar system for measurements of the base and interior of the East Antarctic Ice Sheet. We designed the radar to be of high power (4000-W peak) yet portable and to be able to operate with 60 ...

Deformation and recrystallization texture and microstructure evolution of thin grain-oriented silicon steel sheets

open access: yes工程科学学报, 2015
Combined with magnetic property measurements of thin grain-oriented silicon steel sheets annealed to different recrys-tallization stages, the deformation and recrystallization texture and microstructure evolution of the sheets was analyzed by using the ...

Bayes-Optimal Set-Valued Tracking of Single Point Targets

open access: yesIEEE Access, 2021
Conventional single-point-target tracking algorithms are recursive point estimators with point-measurement input data. In less well-known approaches, the tracking algorithm is a recursive set estimator with point-measurement or set-measurement input data.
