Empirical research in DEM accuracy assessment has observed that DEM errors are correlated with terrain morphology, sampling density, and interpolation method. However, theoretical reasons for these correlations have not been accounted for. This paper introduces approximation theory adapted from computational science as a new framework to assess the accuracy of DEMs interpolated from topographic...

Mutations affecting the conversion of spectrin dimers to tetramers result in hereditary elliptocytosis (HE), whereas a deficiency of human erythroid alpha- or beta-spectrin results in hereditary spherocytosis (HS). All spontaneous mutant mice with cytoskeletal deficiencies of spectrin reported to date have HS. Here, the first spontaneous mouse mutant, sph(Dem)/ sph(Dem), with severe HE is descr...

We investigated the relationship between markers of mitochondrial biogenesis, cell signaling, and antioxidant enzymes by depleting skeletal muscle glutathione with diethyl maleate (DEM) which resulted in a demonstrable increase in oxidative stress during exercise. Animals were divided into six groups: (1) sedentary control rats; (2) sedentary rats + DEM; (3) exercise control rats euthanized imm...

In this paper, we borrow from blind noise parameter estimation (BNPE) methodology early developed in the image processing field an original and innovative no-reference approach to estimate Digital Elevation Model (DEM) vertical error parameters without resorting to a reference DEM. The challenges associated with the proposed approach related to the physical nature of the error and its multifact...

A raster grid with 1m spacing was created using simple kriging from LiDAR point clouds. The 2, 3, 4, 5, 8, and 10 m resolution were created from the original 1 m DEM using nearest neighbor resampling method. The derived DEM were used to study the sensitivity of terrain attributes while changing DEM resolution and possibly introduce a minimum required resolution for the study area. A variety of ...

the aim of the study is the classification of landform based on elevation, slope, relief and curvature inputs (old method) and topographic position index (tpi) (new method) in the south of bojnoord. the input data for the two methods is a digital elevation model (dem). the results of topographic position index (tpi) model showed that most area of landform were covered by class 5 (plains small) ...

In HPVis wird eine Programmierschnittstelle (API) entwickelt, die dem Programmierer die Kommunikation mit einem FPGA-Board erleichtert. Eine rechenintensive Applikation wird in parallele Prozesse aufgeteilt. So können bestimmte Prozesse der Gesamtapplikation auf das FPGA ausgelagert werden. Die API wird durch die Angabe der beteiligten Prozesse sowie deren Kommunikationskanäle untereinander in ...

In this paper, we introduce the results of automatic registration, bundle adjustment, and DEM generation from panoramic close-range images taken on the 1997 Mars Pathfinder mission. Image registration is based on Förstner interest points, cross-correlation coefficient-based matching, parallax verification, and graph consistency verification. A free-network approach is used for bundle adjustment...

Das Provisioning Tool automaIT wurde prototypisch um die Möglichkeit eines Data Discovery erweitert, mit dem Ziel nicht durch automaIT verwaltete Systeme anbinden und steuern zu können. Daten aus dem Data Discovery werden mittels dem Tool Facter gesammelt und können dynamisch in ausführbare Modelle von automaIT integriert und ausgewertet werden. Dadurch kann der Verlauf weiterer Provisionierung...
