Fourier transform spectroscopy emissionspectroscopy Earth observation stratospheric chemistry
2015/9/16
Fourier transform emission spectroscopy can make an important contribution in the observation of the Earth's atmosphere and in the investigation of atmospheric physics and chemistry. In this paper, we...
MAPPING LAND COVER IN THE TAITA HILLS, SE KENYA, USING AIRBORNE LASER SCANNING AND IMAGING SPECTROSCOPY DATA FUSION
GEOBIA LCCS Hyperspectral data
2015/5/7
The Taita Hills, located in south-eastern Kenya, is one of the world’s biodiversity hotspots. Despite the recognized ecological importance of this region, the landscape has been heavily fragmented d...
Detecting supercounterfluidity by Ramsey spectroscopy
Two-component system ultracold atomic optical lattice condensed matter the particles
2014/12/20
A two-component system of ultracold atoms in an optical lattice at integer total filling factor and strong enough onsite repulsion can form a supercounterfluid (SCF) phase, which can be viewed as the ...
Proton magnetic resonance spectroscopy reveals increased hepatic lipid content after a single high-fat meal with no additional modulation by added protein
H-MRS IHL IMCL postprandial protein
2018/12/20
Background: Fat accumulation in nonadipose tissue is linked to insulin resistance and metabolic diseases. Earlier studies have shown that hepatic lipid accumulation can occur after 4 d of a high-fat d...
Discriminant analysis of Olomouc curd cheese by Fourier transform near infrared spectroscopy
ripening Mahalanobis distance
2014/3/28
We used the discriminant analysis of curd cheese during storage by Fourier transform near infrared spectroscopy method (FT-NIRs). Olomouc curd cheese samples were stored at 5 and at 20°C during seven ...
