The SAR Interferometry is a tecnique for measuring the topography of surface and its change through the phase component of a coherent radar signal [1]. This paper reports on the results of the SAR Interferometry application to the study to the Sarno landslide. Two ERS-1/2 tandem pairs acquired over the Sarno area after the 1998 landslide have been processed to generate a SAR DEM. Due to the str...

Background. Oculomotor dysfunction (OMD) is one of many visual anomalies that can be successfully treated with optometric vision therapy (OVT). A widely used diagnostic indicator of OMD is a low score on the Developmental Eye Movement test (DEM) Ratio. Methods. Thirty-six subjects with OMD per a DEM Ratio standard score of 92 or lower were retested with DEM one or more years later. None of the ...

Computational Fluid Dynamics (CFD) and Discrete Element Modelling (DEM) studies relevant to inhaled drug delivery are reviewed. CFD is widely used in device design to determine airflow patterns and turbulence levels. CFD is also used to simulate particles and droplets, which are subjected to various forces, turbulence and wall interactions. These studies can now be performed routinely because o...

We report on the synthesis of the Discrete Element Method (DEM) modelling the behaviour of granular materials and a finite volume model for the continuous interstitial fluid using Computational Fluid Dynamics (CFD). DEM captures the physics of granular materials best but is computationally time-consuming. For this reason, the DEM is complemented by a Discrete Phase Model (DPM) for disperse gran...

INTRODUCTION Social functioning is a core domain in the life of people with dementia, but there is no accepted instrument to measure it. We aimed to develop the Social Functioning in Dementia (SF-DEM) scale and test its psychometric properties for assessing social function in people with dementia. METHODS We interviewed people with mild dementia and family caregivers to develop patient and ca...

including baseline length and tilt. Successful implementation Ground tie points have been used to improve the accuracy of a DEM derived from interferometric SAR (I~SAR) data. The number of tie points required for ensuring certain accuracy of the I~SAR-derived DEM was investigated in this study in two ways. One is the least-squares estimate of the corrections to a DEM using tie points, and the o...

A geometric representation for images is studied in this work. This is based on two complementary geometric structures for the topographic representation of an image. The first one computes a description of the Morse structure, while the second one computes a simplified version of drainage structures. The topographic significance of the Morse and drainage structures of Digital Elevation Maps (D...

Seit Mitte der 90er Jahre entwickelte sich eLearning an der TUM auf Initiative einiger Hochschullehrer und mit Hilfe unterschiedlicher Fördermaßnahmen wie dem MEILEProgramm und dem Förderprogramm „Neue Medien in der Bildung“. Dadurch entstanden meist von einander unabhängige eLearning-Bausteine zur Bereicherung der Präsenzlehre, die nicht in ein eLearning-Konzept der Hochschule eingebunden ware...

A Digital Elevation Model (DEM) refers to a quantitative model of a part of the earth’s surface in digital form (Burrough and McDonnell, 1998). A DEM consists of either (1) a twodimensional array of numbers that represents the spatial distribution of elevations on a regular grid; (2) a set of x, y, and z coordinates for an irregular network of points; or (3) contour strings stored in the form o...

The Interferometric Point Target Analysis (IPTA) technique was applied to Izu-Oshima volcano, Japan, using both JERS SAR data from 1992 to 1998 and a 50-meter mesh digital elevation model (DEM) measured in 1981. The caldera region showed significant extension in the radar line-of-sight (LOS) at a maximum rate of 4 cm/yr around the 1986 eruption vent. Also, the DEM turns out be corrected by 10-3...
