AN OPEN SOURCE APPROACH FOR THE INTRINSIC ASSESSMENT OF THE TEMPORAL ACCURACY, UP-TO-DATENESS AND LINEAGE OF OPENSTREETMAP
Data Quality Lineage Open Source OpenStreetMap Temporal Accuracy Thematic Accuracy Up-to-dateness
2018/11/8
OpenStreetMap (OSM) is the most popular crowdsourced geographic information project. The main factor that still limits the practical use of OSM is the lack of quality assurance. OSM quality assessment...
POINT CLOUD REFINEMENT WITH A TARGET-FREE INTRINSIC CALIBRATION OF A MOBILE MULTI-BEAM LIDAR SYSTEM
LIDAR Intrinsic Calibration Mobile Mapping 3D Automatic Computer Processing Velodyne
2016/7/27
LIDAR sensors are widely used in mobile mapping systems. The mobile mapping platforms allow to have fast acquisition in cities for example, which would take much longer with static mapping systems. Th...
Estimating Intrinsic Accuracy of Airborne Laser Data with Local 3D-Offsets

2015/5/26
Airborne laser systems provide a three-dimensional (3D) perception of the Earth’s topography with clouds of points. Whereas the
technique ensures a high theoritical quality, one can observe discrepan...
Relationship between intrinsic viscosity, thermal and retrogradation properties of amylose and amylopectin
DSC enthalpy storage corn starch
2014/10/11
The relationships between intrinsic viscosity and some properties of amylose and amylopectin were investigated. The intrinsic viscosities determined by Ubbelohde viscometer for rice, maize, wrinkled p...

A miniature surface plasmon resonance sensor is fabricated from a gold-coated standard optical fiber with an in-core tilted fiber Bragg grating fabricated by UV exposure. The sensor h...
Intrinsic Reactivity of Gold Nanoparticles: Classical, Semi- Empirical and DFT Studies
Gold catalysis Chemisorption Nanoparticles Fermi level
2009/7/28
Gold nanoparticles used in most experiments(1-10 nm) in gold catalysis show varying degrees of
reactivity, with particles below 5 nm generally beingmore reactive. The origin of this ctivity is a subj...
Crystal growth nucleation and Fermi energy equalization of intrinsic spherical nuclei in glass-forming melts
metallic glasses intrinsic growth nuclei crystal nucleation
2010/1/18
The energy saving resulting from the equalization of Fermi energies of a crystal and its melt is added to the Gibbs free-energy change ΔG2ls associated with a crystal formation in glass-forming melts....
Intrinsic Activity of Inulinase from Kluyveromyces marxianus ATCC 16045 and Carbon and Nitrogen Balances
carbon source nitrogen source inulinase production
2009/3/6
Kluyveromyces marxianus ATCC 16045 was cultivated in a batch on minimal medium to overproduce inulinase. The fermented broth was purified by fast protein liquid chromatography and ultrafiltration, and...
Material Dispersion in Intrinsic GaAs for the Far-Infrared Range
Material dispersion GaAs far-infrared group index
2010/12/9
An expression for the coefficient of material dispersion in intrinsic gallium arsenide for the far-infrared range is derived. From this result, the variation of the group index in the above range is d...
