  2. 16. On Non Parametric Regression and Panel Unit Root Testing

    Author : Xijia Liu; Rolf Larsson; Johan Lyhagen; Niklas Ahlgren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : In this thesis, two different issues in econometrics are studied, the estimation of regression coefficients and the non-stationartiy analysis in a panel setting.Regarding the first topic, we study a set of measure of location-based estimators (MLBEs) for the slope parameter in a linear regression model with a single stochastic regressor.

  4. 17. Representing Future Situations of Service : Prototyping in Service Design

    Author : Johan Blomkvist; Stefan Holmlid; Robert Ramberg; Daniel Kindström; Youn-kyung Lim; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; service design; situated cognition; prototyping; representations; tjänstedesign; situerad kognition; prototypande; representationer;

    Abstract : This thesis describes prototyping in service design through the theoretical lens of situated cognition. The research questions are what a service prototype is, what the benefits of service prototyping are, and how prototypes aid in the process of designing services. Four papers are included. READ MORE

  5. 18. Movement Behaviors and Cognitive Health for Office Workers

    Author : Emil Bojsen-Møller; Maria Ekblom; Jonna Nilsson; Carl-Johan Boraxbekk; Teresa Liu-Ambrose; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Movement behavior; Physical activity; Sedentary behavior; cognitive functions; neuroplasticity; Medicin Teknik; Medicine Technology;

    Abstract : The lifetime trajectories of movement behavior and cognitive functioning depend on complex interactions between genetic and environmental factors. There is substantial evidence suggesting that physical activity benefits cognitive functions. However, how sedentary behavior and the composition of movement behaviors (i.e. READ MORE

    Abstract : The subject of this thesis is a new chip to substrate interconnection technique using self-aligning elastic chip sockets. This work was focused on the technology steps which are necessary to fulfill in order to realize the suggested technique. READ MORE

  7. 20. Optical measurements in brain tissue during radio frequency lesioning

    Author : Johan Antonsson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Radio frequency (RF) lesioning is a well well-known procedure within the field of stereotactic neurosurgery, commonly used for the treatment of movement disorders. During the intervention, an RF-electrode is inserted into the deeper parts of the brain, where a small volume of malfunctioning brain tissue will be coagulated. READ MORE
