METHODOLOGY FOR THE EXTRACTION OF HOMOLOGOUS POINTS FROM A DEM/DSM TO EVALUATE THE RELATIVE POSITIONAL ACCURACY
(Univ Federal Parana, Centro Politecnico, 2020-01-01)
This work presents a new methodology for extracting 3D homologous points from a DEM/DSM for relative evaluation of positional accuracies, from terrain features such as ridgelines and hydrography. Firstly, it extracts 3D ...
A prospective multicentre diagnostic accuracy study for the Truenat tuberculosis assays
(European Respiratory Society, 2021)
BACKGROUND: Bringing reliable and accurate tuberculosis (TB) diagnosis closer to patients is a key priority for global TB control. Molbio Diagnostics have developed the Truenat point-of-care molecular assays for detection ...
Galileo's surveying potential E5 pseudorange precision
(2012-03-01)
New Galileo signals have great potential for pseudorange-based surveying and mapping in both optimal open-sky conditions and suboptimal under-canopy environments. This article reviews the main features of Galileo's E5 ...
Diagnostic accuracy of the EMG parameters associated with anterior knee pain in the diagnosis of patellofemoral pain syndrome
(2014)
Objective To assess the diagnostic accuracy of the surface electromyography (sEMG) parameters associated with referred anterior knee pain in diagnosing patellofemoral pain syndrome (PFPS). Design Sensitivity and specificity ...

A Note on Methods for Vertical Accuracy Assessment of DEMs
(2017)
This study investigates the vertical accuracy of a DEMs interpolated from 1:50,000
contours with universal kriging (UK) using DEMs interpolated from 1:10,000 contours as the
independent source of higher accuracy following ...
