Ensemble Learning for Blending Gridded Satellite and Gauge-Measured Precipitation Data

open access: yesRemote Sensing, 2023
Regression algorithms are regularly used for improving the accuracy of satellite precipitation products. In this context, satellite precipitation and topography data are the predictor variables, and gauged-measured precipitation data are the dependent ...

GEOSPATIAL MONITORING OF ENGINEERING STRUCTURES AS A PART OF BIM [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Among the various civil engineering tasks, geospatial monitoring of engineering structures takes an essential place. In the digital era, the concept of geospatial monitoring needs a total re-definition.

Parametric mechanical analysis of thin- versus thick-skinned tectonics applied to the Jura belt

open access: yesBSGF - Earth Sciences Bulletin, 2023
Field observations and seismic interpretations testify that the front of the Jura fold-and-thrust belt is still submitted to compressive deformation, but whether the basement is deforming (thick-skinned) or not (thin-skinned) is an active question.

Reconnecting a Fragmented Monument through Digital Mapping: The City Walls of Athens

open access: yesStudies in Digital Heritage, 2019
The fortifications of Athens have been a recurrent theme of archaeological investigation. In the past two centuries, parts of the walls have been located during rescue interventions at numerous sites in the urban fabric. At present, the visibility of the

Corneal topography with an aberrometry-topography system [PDF]

open access: yesContact Lens and Anterior Eye, 2018
To investigate the agreement between the central corneal radii and corneal eccentricity measurements generated by the new Wave Analyzer 700 Medica (WAV) compared to the Keratograph 4 (KER) and to test the repeatability of the instruments.20 subjects (10 male, mean age 29.1 years, range 21-50 years) were recruited from the students and staff of the ...

Wettability influences cell behavior on superhydrophobic surfaces with different topographies [PDF]

open access: yes, 2012
Surface wettability and topography are recognized as critical factors influencing cell behavior on biomaterials. So far only few works have reported cell responses on surfaces exhibiting extreme wettability in combination with surface topography.

A BIM-IFC Technical Solution for 3D Crowdsourced Cadastral Surveys Based on LADM

open access: yesEarth, 2021
In most countries, three-dimensional (3D) property units are registered utilizing two-dimensional (2D) documentation and textual description. This approach has several limitations as it is unable to represent the actual extent of complicated 3D property ...

Comparison of Tree-Based Ensemble Algorithms for Merging Satellite and Earth-Observed Precipitation Data at the Daily Time Scale

open access: yesHydrology, 2023
Merging satellite products and ground-based measurements is often required for obtaining precipitation datasets that simultaneously cover large regions with high density and are more accurate than pure satellite precipitation products.

Curvature sensor for the measurement of the static corneal topography and the dynamic tear film topography in the human eye [PDF]

open access: yes, 2005
A system to measure the topography of the first optical surface of the human eye noninvasively by using a curvature sensor is described. The static corneal topography and the dynamic topography of the tear film can both be measured, and the topographies ...
