Deformation analysis by an improved similarity transformation
Applied Computing and GeosciencesIn this contribution, deformation analysis is rigorously performed by a non-linear 3-D similarity transformation. In contrast to traditional methods based on linear least-squares (LLS), here we solve a non-linear problem without any linearization.

Long term Ultra-Violet Variability of Seyfert galaxies [PDF]
, 2018 Flux variability is one of the defining characteristics of Seyfert galaxies, a class of active galactic nuclei (AGN). Though these variations are observed over a wide range of wavelengths, results on their flux variability characteristics in the ultra ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

A weighted adjustment of a similarity transformation between two point sets containing errors
Journal of Geodetic Science, 2017 For an adjustment of a similarity transformation, it is often appropriate to consider that both the source and the target coordinates of the transformation are affected by errors.

An Improved Point-to-Plane Registration Method for Terrestrial Laser Scanning Data
IEEE Access, 2018 Registration of point clouds is vital in point cloud data processing. By registering, the point cloud data from different views are transformed into a common coordinate system.
