  2. 1. Undifferenced GPS for Deformation Monitoring

    Author : Johan Vium Andersson; Lars Sjöberg; Jonas Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : deformation monitoring; GPS; modified NGS-parameters; undifferenced GPS-observations; Kalman filter; Geoengineering; Geoteknik;

    Abstract : This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. READ MORE

  4. 2. Automated performance monitoring of concrete dams

    Author : Christian Bernstone; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; teknisk geologi; geographical and geological engineering; Maintenance; Uplift pressure; Crack; Deformation; Image processing; Dams; Condition monitoring; Time-domain reflectometry; GPS; Image analysis; Concrete structures; teknisk geografi; Hydrogeology;

    Abstract : The Swedish hydropower industry operates a large number of power plants and dams geographically spread over the country. The level of safety of a specific dam is to a large extent determined during the design and construction phases that in the case of Swedish hydropower plants took place several decades ago.

  5. 3. A Complete Model for Displacement Monitoring Based on Undifferenced GPS Observations

    Author : Johan Vium Andersson; Lars Sjöberg; Milan Horemuz; Jan Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Undifferenced GPS observations; Real-time displacement monitoring; Early warning system; CUSUM; Surveying; Lantmäteri;

    Abstract : During recent years there has been a great focus on the climate changes within the media. More or less every day more newspaper articles are presented about the global warming issue and the effect on us human race. Climate models predict higher temperatures and more rain in the northern part of Europe. READ MORE

  6. 4. Urban Travel Time Estimation from Sparse GPS Data : An Efficient and Scalable Approach

    Author : Mahmood Rahmani; Harilaos Koutsopoulos; Nikolas Geroliminis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; map-matching; path inference; sparse GPS probes; floating car data; arterial; urban area; digital road network; iterative travel time estimation; fixed point problem; Stockholm; taxi; Transportvetenskap; Transport Science;

    Abstract : The use of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place, with significant number of mobile sensors moving around covering expansive areas of the road network. Many travelers carry with them at least one device with a built-in GPS receiver. READ MORE

  7. 5. Path Inference of Sparse GPS Probes for Urban Networks : Methods and Applications

    Author : Mahmood Rahmani; Harilaos Koutsopoulos; Clas Rydergren; KTH; []
