  2. 1. Human-Robot Interaction for Semi-Autonomous Assistive Robots : Empirical Studies and an Interaction Concept for Supporting Elderly People at Home

    Author : Marcus Mast; Arne Jönsson; Michael Burmester; Jonas Lundberg; Tony Belpaeme; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semi-autonomous assistive robots; human-robot interaction; user interface design; teleoperation; telemanipulation; elderly people; global environment maps; stereoscopy; Semi-autonoma robotar; människa-robotinteraktion; gränssnittsdesign; distansstyrning; distansmanipulation; äldre; globala omgivningskartor; stereoskopisk;

    Abstract : The research addresses current shortcomings of autonomous service robots operating in domestic environments by considering the concept of a semi-autonomous robot that would be supported by human remote operators whenever the robot cannot handle a task autonomously. The main research objective was to investigate how to design the human-robot interaction for a robotic system to assist elderly people with physical tasks at home according to this conceptual idea.

    Abstract : This thesis presents studies of semi-Markov models for insurance and option rewards. The thesis consists of the introduction and six papers. The introduction presents the results of the thesis in an informal way.In paper A, a general semi-Markov reward model is presented. READ MORE

  5. 3. Semi Markov chain Monte Carlo

    Author : Håkan Ljung; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Adaptive simulation; error-in-the-variables; Kullback-Leibler divergence; Markov chain simulation; Markov chain Monte Carlo; semi-regenerative; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk statistik; Mathematical Statistics;

    Abstract : The first paper introduces a new simulation technique, called semi Markov chain Monte Carlo, suitable for estimating the expectation of a fixed function over a distribution π, Eπf(χ). Given a Markov chain with stationary distribution p, for example a Markov chain corresponding to a Markov chain Monte Carlo algorithm, an embedded Markov renewal process is used to divide the trajectory into different parts.

  6. 4. The Establishment of Semi-Presidential Regimes : A Mixed Methods Approach to How and Why

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Semi-presidentialism; regime type; constitutional choice; diffusion; legacies; transitional bargaining; Intercultural Studies; Interkulturella studier;

    Abstract : One of the crucial constitutional choices made in a democratizing or recently independent state is the structure of executive-legislative relations that forms into a parliamentary, presidential, or semi-presidential regime. Even so, only a few studies have sought the reasons for the establishment and least of all is known when it comes to the most recent of them: the semi-presidential one. READ MORE

  7. 5. Restoration of semi-natural grasslands : Impacts on biodiversity, ecosystem services and stakeholder perceptions

    Author : Emelie Waldén; Regina Lindborg; Sara A O Cousins; Erik Öckinger; Aveliina Helm; Stockholms universitet; []

    Abstract : Humans play a major role shaping the living conditions for not only ourselves, but also all other species on Earth. In fact, some species-rich habitat types require human management to uphold the biodiversity and related ecosystem services. READ MORE
