  1. 1. Dynamic Queries

    Författare :Christopher Ahlberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dynamic queries is an approach to database querying, information exploration, and information retrieval. Building on principles of direct manipulation, dynamic queries utilizes visualizations and graphical query devices to allow users to visually explore, browse, and query large datasets. LÄS MER

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

    Författare :Ola Bengtsson; Christian Schlegel; Chalmers tekniska högskola Göteborg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile robot; Self-localization; Scan matching algorithm; Changed environments; Dynamic environments; o-variance matrix; Kalman filter; Signal processing; Signalbehandling;

    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

  4. 3. Repeated Path Planning for Mobile Robots in Dynamic Environments

    Författare :Maarja Kruusmaa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision-making; mobile robot; case-based reasoning; navigation; dynamic environments; path planning;

    Sammanfattning : This thesis presents a global navigation strategy for repeated traverse of mobile robots in dynamic environments. The research is motivated by the fact that most real-world applications of mobile robotics imply repeated traverse between predefined target points in large, uncertain real-world domains. LÄS MER

  5. 4. Shared Virtual Environments : Technology, Social Interaction, and Adaptation over Time

    Författare :Maria Spante; Erik Stolterman; Institutionen för teknik och samhälle Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Shared virtual environments; virtual reality technology; social interaction; adaptation; collaboration; time; Informatik; Informatics;

    Sammanfattning : This thesis investigates social interaction and adaptation over time in shared virtual environments. Shared virtual environments (SVEs) are computer generated 3D graphical spaces where geographically distributed people can meet and interact with each other in a graphical space. LÄS MER

  7. 5. Dynamic Software Architectures

    Författare :Jesper Andersson; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Software architecture; Dynamic re-configuration; Software engineering; Programvaruteknik; Data- och informationsvetenskap; Computer and Information Sciences Computer Science; Computer science;

    Sammanfattning : Software architecture is a software engineering discipline that provides notations and processes for high-level partitioning of systems' responsibilities early in the software design process. This thesis is concerned with a specific subclass of systems, systems with a dynamic software architecture. LÄS MER
