  1. 21. Techniques for Fast and High-Quality 3D Reconstruction of General Scenes

    Författare :Sverker Rasmuson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; voxels; 3D reconstruction; computer vision; computer graphics; volumetric video;

    Sammanfattning : This thesis is a collection of techniques used for 3D reconstruction; the creation of 3D models from real world objects or scenes. Given the increase in accuracy, robustness and speed of modern methods and algorithms, new and exciting applications of this technology is constantly appearing. LÄS MER

  3. 22. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  4. 23. Usable privacy for digital transactions : Exploring the usability aspects of three privacy enhancing mechanisms

    Författare :Julio Angulo; John Sören Pettersson; Simone Fischer-Hübner; Erik Wästlund; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Privacy-Enhancing Technologies; usability; usable privacy; mental models; mobile devices; security; digital transactions; e-commerce; User Interfaces; Information Systems; Informatik;

    Sammanfattning : The amount of personal identifiable information that people distribute over different online services has grown rapidly and considerably over the last decades. This has led to increased probabilities for identity theft, profiling and linkability attacks, which can in turn not only result in a threat to people’s personal dignity, finances, and many other aspects of their lives, but also to societies in general.

  5. 24. Cognition reversed : Robot learning from demonstration

    Författare :Erik Billing; Lars Erik Janlert; Thomas Hellström; Tom Ziemke; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Cognitive science; Kognitionsvetenskap; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : The work presented in this thesis investigates techniques for learning from demonstration (LFD). LFD is a well established approach to robot learning, where a teacher demonstrates a behavior to a robot pupil. This thesis focuses on LFD where a human teacher demonstrates a behavior by controlling the robot via teleoperation. LÄS MER

  7. 25. Obtaining Accurate and Comprehensible Data Mining Models : An Evolutionary Approach

    Författare :Ulf Johansson; Lars Niklasson; Tom Ziemke; Thorsteinn Rögnvaldsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rule extraction; Ensembles; Data mining; Genetic programming; Artificial neural networks; Computer science; Datalogi;

    Sammanfattning : When performing predictive data mining, the use of ensembles is claimed to virtually guarantee increased accuracy compared to the use of single models. Unfortunately, the problem of how to maximize ensemble accuracy is far from solved. LÄS MER
