  1. 1. Hydropower generator and power system interaction

    Author : Johan Bladh; Urban Lundin; Rafael Escarela-Perez; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amortisseur windings; applied voltage test; automatic voltage regulators; damper windings; damping torque; empirical modelling; equivalent circuits; excitation control; finite element method; hydropower generators; power system restoration; power system stability; synchronous machines; self excitation; shaft torque amplification; short circuit test; single machine infinite bus; slip test; standstill frequency response test; subsynchronous oscillations; synchronising torque; synchronous generators; torsional interaction.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : After decades of routine operation, the hydropower industry faces new challenges. Large-scale integration of other renewable sources of generation in the power system accentuates the role of hydropower as a regulating resource. READ MORE

  2. 2. Exploring self-efficacy in end-user programming : a feminist approach

    Author : Lena Palmquist; Anna Croon Fors; Anders Broberg; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; end-user development; technological self-efficacy; gender HCI; interaction design; människa-datorinteraktion; människa-datorinteraktion;

    Abstract : Digital services and devices are today more spread than ever, forming a basis for new innovations, even among ordinary people. And yet, producers of such services and devices are mostly men with programming skills. Women's participation in development and design of digital products is thus not yet as influential as that of men. READ MORE

  3. 3. Egocentric interaction for ambient intelligence

    Author : Dipak Surie; Lars-Erik Janlert; Thomas Pederson; Hans Gellersen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ambient Intelligence; Human-Computer Interaction; Context-Aware computing; Ubiquitous Computing; Mixed-Reality; Smart Environments; Activity-Based Computing; Ambient Ecology; business data processing; administrativ databehandling;

    Abstract : Ambient intelligence refers to the vision of computationally augmented everyday environments that are sensitive, adaptive and responsive to humans and intelligently support their daily lives. Ambient ecologies are the infrastructures of ambient intelligence. READ MORE

  4. 4. How Does it Feel and How is it measured? Assessing Sitting Comfort and Postures of Rear-Seated Car Passengers in Stationary and Driven Scenarios Over Time

    Author : Melina Makris; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sitting posture; sitting comfort; driving study; stationary study; seat belt fit; car comfort; car passenger; mixed-methods; seat belt comfort;

    Abstract : This licentiate thesis presents the results of an empirical study focused on examining the comparative effectiveness of short stationary studies versus long driving studies in evaluating sitting postures, belt fit, and sitting comfort in cars. The study employed a mixed-methods approach, in which 19 participants experienced two different test scenarios in the rear seat of a car: a stationary scenario within an indoor garage and a driven scenario on a predefined route in regular traffic, each lasting 45 minutes.

  5. 5. The driver response process in assisted and automated driving

    Author : Linda Pipkorn; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automation safety; take-over request; driver behavior; response process; automated driving; driving performance;

    Abstract : Background: Safe assisted and automated driving can be achieved through a detailed understanding of the driver response process (the timing and quality of driver actions and visual behavior) triggered by an event such as a take-over request or a safety-relevant event. Importantly, most current evidence on driver response process in vehicle automation, and on automation effects (unsafe response process) is based on driving-simulator studies, whose results may not generalize to the real world.
