  1. 16. Perceive those things which cannot be seen : A cognitive systems engineering perspective on requirements management

    Author : Åsa Hedenskog; Rune Gustavsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software tools; Usability requirements; Cognitive systems engineering; Systems engineering; Systemteknik;

    Abstract : Non-functional requirements contribute to the overall quality of software, and should therefore be a part of any development effort. However, in practice they are often considered to be too difficult to handle. The purpose of this thesis is to gain understanding of where the nature and origin of these difficulties may lie.

  2. 17. Multivariate Data Analytics to Identify Driver’s Sleepiness, Cognitive load, and Stress

    Author : Shaibal Barua; Shahina Begum; Peter Funk; Mobyen Uddin Ahmed; Christer Ahlström; Nirmalie Wiratunga; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Driver monitoring; Driver state; Physiological signals; Machine learning; Contextual information; Computer Science; datavetenskap;

    Abstract : Driving a vehicle in a dynamic traffic environment requires continuous adaptation of a complex manifold of physiological and cognitive activities. Impaired driving due to, for example, sleepiness, inattention, cognitive load or stress, affects one’s ability to adapt, predict and react to upcoming traffic events. READ MORE

  3. 18. An Intelligent Non-Contact based Approach for Monitoring Driver’s Cognitive Load

    Author : Hamidur Rahman; Shahina Begum; Mobyen Uddin Ahmed; Peter Funk; Jerker Westin; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : The modern cars have been equipped with advanced technical features to help make driving faster, safer and comfortable. However, to enhance transport security i.e. to avoid unexpected traffic accidents it is necessary to consider a vehicle driver as a part of the environment and need to monitor driver’s health and mental state.

  4. 19. Geometric Models of Similarity

    Author : Mikael Johannesson; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; symmetry; similarity; separable dimensions; prominence; multidimensional scaling; Minkowski metric; machine learning; integral dimensions; familiarity; geometric models; distance metric; asymmetry; conceptual spaces; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Geometry; algebraic topology; Geometri; algebraisk topologi;

    Abstract : This dissertation examines and discusses some phenomena related to the geometric representation of similarity. It takes its inspiration from the existing body of empirical research within the fields of perceptual and cognitive psychology, but also connects to certain areas of machine learning. READ MORE

  5. 20. Perceptual Surface Reconstruction

    Author : Jens Månsson; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; system; kontroll; Psychology; Psykologi; numerisk analys; Datalogi; systems; control; numerical analysis; Surface; Contour; Depth; Vision; Binocular; Computer science;

    Abstract : How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theoretical and computational perspective, as well as through empirical investigations. In paper one, the fundamentals of stereopsis are briefly reviewed, and the difficulties related with resolving the (stereo) correspondence problem are particularly discussed. READ MORE
