Retrieval of sea level and surface loading variations from geodetic observations and model simulations: an integrated approach
Rietbroek, Roelof (2015)The mass distribution in the system Earth changes dynamically over time. Time-variable mass transport mainly arises from the interplay between the terrestrial hydrological water cycle, the ocean and atmosphere, and the ... -
Robot mapping and navigation in real-world environments
Bogoslavskyi, Igor (2020)Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ... -
Robust determination of station positions and Earth orientation parameters by VLBI intra-technique combination
Böckmann, Sarah (2011)In this thesis, it is shown that combining contributions of different VLBI analysis centers, a so called intratechnique combination, improves the robustness and stability of the final VLBI results. For this purpose, a ... -
Robust Wide-Baseline Stereo Matching for Sparsely Textured Scenes
Dickscheid, Timo (2013)The task of wide baseline stereo matching algorithms is to identify corresponding elements in pairs of overlapping images taken from significantly different viewpoints. Such algorithms are a key ingredient to many computer ... -
Sensor fusion for localization of automated vehicles
Merfels, Christian (2020)Automated vehicles need to precisely know where they are at all times to be able to make informed driving decisions. Therefore, multiple localization systems are typically installed on such vehicles to provide redundant ... -
Sensoren für kinematische Anwendungen: Sensors for Kinematic Applications
Klingbeil, Lasse; Kuhlmann, Heiner (2014)Dieser Artikel bietet einen Überblick über die Sensoren, die in kinematischen Anwendungen zur Bestimmung der Trajektorie einer bewegten Sensorplattform verwendet werden können. Dabei wird insbesondere darauf eingegangen, ... -
Separablity of deformations and measurements noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
Li, Lihua (2012)The separation of the deformations and measurement noise of GPS coordinate time series and accuracy improvement of GPS real-time coordinates are major aspects of the thesis. In order to reduce the influence of the colored ... -
Sequential learning using incremental import vector machines for semantic segmentation
Roscher, Ribana (2013)We propose an innovative machine learning algorithm called incremental import vector machines that is used for classification purposes. The classifier is specifically designed for the task of sequential learning, in which ... -
Simulated satellite formation flights for detecting the temporal variations of the Earth's gravity field
Elsaka, Basem (2010)In this thesis, the concept of satellite formation flight (SFF) is studied by means of simulated satellite observations. With various formation types enabling inter-satellite measurements in various directions (e.g. ... -

Singular Value Decomposition and Cluster Analysis as Regression Diagnostics Tools in Geodetic VLBI
Vennebusch, Markus (2008)It is well known that high-leverage observations significantly affect the estimation of parameters. So far, mainly redundancy numbers have been used for the detection of single high-leverage observations or of single ... -
Socio-environmental impacts of settlement growth under conditions of fostered infill development: A methodological framework for a multicriteria assessment
Schetke, Sophie (2013)The major objective of this study is to analyze socio-environmental conditions under which a sustainable and resource-preserving settlement development can be promoted and to assess respective impacts of greenfield and ... -
Spatio-temporal Correlations of Terrestrial Laser Scanning: Raumzeitliche Korrelationen beim terrestrischen Laserscanning
Kauker, Stephanie; Holst, Christoph; Schwieger, Volker; Kuhlmann, Heiner; Schön, Steffen (2016)This contribution investigates correlations in terrestrial laser scanning on the scientific level. It summarizes recent approaches to model correlations, to develop measurement scenarios for the determination of correlations ... -
Stadtumbau im Konsens!?: zur Leistungsfähigkeit und Fortentwicklung des städtebaulichen Instrumentariums unter Schrumpfungsbedingungen
