  1. 1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Författare :Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Sammanfattning : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. LÄS MER

  2. 2. Robust self-localization of mobile robots in dynamic environments using scan matching algorithms

    Sammanfattning : The most fundamental task for any mobile robot is to perform self-localization in the world in which it is currently active, i.e. determine its position relative its world. Encoders that count wheel rotations are often used, which can be turned into relative position estimates by mean of integration. LÄS MER

    Sammanfattning : From the begiining of the 20th century producer co-operative bacon factories were established in the south of Sweden. In his thesis Lars Hansson studies how class relations were shaped and transformed within this rural industry. LÄS MER

  4. 4. Scan Statistics for Space-Time Cluster Detection

    Författare :Benjamin Allévius; Martin Sköld; Michael Höhle; Paula Moraga-Serrano; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Scan statistics are used by public health agencies to detect and localize disease outbreaks. This thesis provides an overview of scan statistics in the context of prospective disease surveillance and outbreak detection, presents a novel scan statistic to deal with the type of zero-abundant data that is often encountered in these settings, and—perhaps most importantly—implements this and other scan statistics in a freely available and open source R package.
