  2. 6. Robust large-scale mapping and localization : Combining robust sensing and introspection

    Author : Daniel Adolfsson; Henrik Andreasson; Martin Magnusson; Stephanie Lowry; Timothy Barfoot; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SLAM; Localization; Robustness; Radar;

    Abstract : The presence of autonomous systems is rapidly increasing in society and industry. To achieve successful, efficient, and safe deployment of autonomous systems, they must be navigated by means of highly robust localization systems. READ MORE

  4. 7. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation : Comparison of Methods and Climate Regions

    Author : Fredrik Wetterhall; Sven Halldin; Chong-Yu Xu; Lars-Christer Lundin; Deliang Chen; Hans von Storch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Statistical; Downscaling; Precipitation; Large-scale circulation; PCA; TWS; Weather pattern; Regression; Weather generator; Hydrologi; Hydrology; Hydrologi;

    Abstract : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale.

  5. 8. Optimisation methods for solving a large-scale avionics scheduling problem

    Author : Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

    Abstract : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. READ MORE

  6. 9. Analysis of large scale rock slopes

    Author : Jonny Sjöberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : The objective of this work was to (1) increase the knowledge of the behavior of large scale rock slopes, (2) improve the ability to estimate rock mass strength for such slopes, and (3) develop an improved design methodology for forward design of large scale slopes in open pit mining. A fourth objective included the application of the results to the Aitik open pit in northern Sweden. READ MORE

  7. 10. Statistical modeling in international large-scale assessments

    Author : Inga Laukaityte; Marie Wiberg; Kenny Bränberg; Ewa Rolfsman; Bernard Veldkamp; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multilevel model; plausible values; sampling weights; missing information; multiple imputation; non-monotone missing pattern; TIMSS; PISA; Statistics; statistik; pedagogik; Education;

    Abstract : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.
