Evaluation of four gridded climate products for streamflow and drought simulations in the Kelantan River Basin, Malaysia

open access: yesGeocarto International
Gridded climate products (GCPs) play a vital role in hydro-climatic modeling by overcoming the limitations of gauge data. This study compares the performance of the recently launched NASA POWER and ERA5-Land, with CHIRPS and APHRODITE, in simulating ...

Accuracy Analysis of a Dam Model from Drone Surveys

open access: yesSensors, 2017
This paper investigates the accuracy of models obtained by drone surveys. To this end, this work analyzes how the placement of ground control points (GCPs) used to georeference the dense point cloud of a dam affects the resulting three-dimensional (3D ...

MULTI-SCALE MATCHING FOR THE AUTOMATIC LOCATION OF CONTROL POINTS IN LARGE SCALE AERIAL IMAGES USING TERRESTRIAL SCENES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
A technique to automatically locate Ground Control Points (GCPs) in large aerial images is presented considering the availability of low accuracy direct georeferencing data. The approach is based on image chips of GCPs extracted from vertical terrestrial

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

Finite bias Cooper pair splitting

open access: yes, 2011
In a device with a superconductor coupled to two parallel quantum dots (QDs) the electrical tunability of the QD levels can be used to exploit non-classical current correlations due to the splitting of Cooper pairs.

Decomposing Dual Scale Soil Surface Roughness for Microwave Remote Sensing Applications [PDF]

open access: yes, 2012
Soil surface roughness, as investigated in this study, is decomposed in a dual scale process. Therefore, we investigated photogrammetrically acquired roughness information over different agricultural fields in the size of 6-22 m(2) and decomposed them ...

Single flap approach combined with periosteal pedicle flap as a regenerative procedure: A case report

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Single flap approach (SFA) is a validated procedure for obtaining clinical attachment gain and pocket closure when applied to deep intraosseous defects. However, the presence of an interdental crater as well as the tooth location were associated with a lower rate of primary intention closure, possibly jeopardizing the outcome of the

Ground-Control Networks for Image Based Surface Reconstruction: An Investigation of Optimum Survey Designs Using UAV Derived Imagery and Structure-from-Motion Photogrammetry

open access: yesRemote Sensing, 2016
The use of small UAV (Unmanned Aerial Vehicle) and Structure-from-Motion (SfM) with Multi-View Stereopsis (MVS) for acquiring survey datasets is now commonplace, however, aspects of the SfM-MVS workflow require further validation.
