  2. 1. Talk the walk : Empirical studies and data-driven methods for geographical natural language applications

    Author : Jana Götze; Johan Boye; Martin Raubal; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pedestrian wayfinding; salience; route instructions; reference resolution; Computer Science; Datalogi;

    Abstract : Finding the way in known and unknown city environments is a task that all pedestrians carry out regularly. Current technology allows the use of smart devices as aids that can give automatic verbal route directions on the basis of the pedestrian's current position. READ MORE

  4. 2. Power System Damping - Structural Aspects of Controlling Active Power

    Author : Olof Samuelsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information Retrieval; GIR; Framework; Indexing; Retrieval Model; Other information technology; Övrig informationsteknik;

    Abstract : Geographic information is one of the most important and the most common types of information in human society. It is estimated that more than 70% of all information in the world has some kind of geographic features. READ MORE

  6. 4. Stochastic Modeling and Management of an Emergency Call Center : A Case Study at the Swedish Emergency CallCenter Provider, SOS Alarm Sverige AB

    Author : Klas Gustavsson; Leif Olsson; Panagiotis Papapetrou; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Call Center Management; Burst Modeling; Stochastic Resources; Skills-Based Routing; Discrete-Event-Simulation;

    Abstract : A key task of managing an inbound call center is in estimating its performance and consequently plan its capacity, which can be considered a complex task since several system variables are stochastic. These issues are highly crucial for certain time-sensitive services, such as emergency call services. READ MORE

  7. 5. Work and Technology Use in Centers of Coordination : Reflections on the relationship between situated practice and artifact design

    Author : Maria Normark; Kerstin Severinsson Eklundh; Susanne Bødker; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sociology; Sociologi; Computer and systems science; Data- och systemvetenskap;

    Abstract : The research problem explored in this thesis is how technology and work practice are related in coordinative situations (collocated and over distance). Further, the problem of how this kind of research results can be transformed and used in the development of new technology is discussed. READ MORE
