  1. 1. Enhancing Salient Features in Volumetric Data Using Illumination and Transfer Functions

    Författare :Daniel Jönsson; Anders Ynnerman; Kwan-Liu Ma; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The visualization of volume data is a fundamental component in the medical domain. Volume data is used in the clinical work-flow to diagnose patients and is therefore of uttermost importance. LÄS MER

  2. 2. Perceptually motivated speech recognition and mispronunciation detection

    Författare :Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

    Sammanfattning : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. LÄS MER

  3. 3. Industrial Digital Fabrication Using Inkjet Technology

    Författare :Ingo Reinhold; Carl-Mikael Zetterling; Matti Mäntysalo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inkjet printing; droplet formation; digital fabrication; sintering; nanoparticles; printed electronics; Industrial Information and Control Systems; Industriella informations- och styrsystem; Media Technology; Medieteknik; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The use of acoustic waves initiated by the deformation of a microchannel is one method for generating monodisperse, micrometer-sized droplets from small orifices and is employed in piezo-electric inkjet printheads. These printheads are used in both graphical printing and digital fabrication, where functionalities, such as optical, biological, electrical or mechanical, are being produced locally. LÄS MER

  4. 4. Travelling through time : Students’ interpretation of evolutionary time in dynamic visualizations

    Författare :Jörgen Stenlund; Lena Tibell; Konrad Schönborn; Niklas Gericke; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolution; visualization; time; learning; threshold; zooming;

    Sammanfattning : Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. LÄS MER

  5. 5. Embodying Politeness in Persuasive Humanoid Agents for Small Group Scenarios

    Författare :Sahba Zojaji; Christopher Peters; Tony Belpaeme; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; politeness; persuasiveness; small free-standing conversational groups; embodiment; embodied conversational agents; humanoid robots; virtual reality; immersiveness; human-agent interaction; social norms; multimodal expressive communication; artighet; övertalningsförmåga; små fristående samtalsgrupper; förkroppsligande; förkroppsligade samtalsagenter; humanoida robotar; virtuell verklighet; uppslukande; interaktion mellan människa och agent; sociala normer; multimodal uttrycksfull kommunikation;

    Sammanfattning : In both physical and virtual environments, small group interactions significantly shape our social experiences. Understanding and replicating situated group interactions with virtual agents or physical robots pose possibilities and challenges. LÄS MER
