  1. 1. A Quantitative Rule System for Musical Performance

    Författare :Anders Friberg; Johan Sundberg; Giovanni Di Poli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; music performance; expression; interpretation; rules; computer music; midi; jnd; time discrimination; locomotion; motion; listening experiment; perception; timing; phrasing; intonation; Speech and Music Communication; Tal- och musikkommunikation;

    Sammanfattning : A rule system is described that translates an input score file to a musical performance. The rules model different principles of interpretation used by real musicians, such as phrasing, punctuation, harmonic and melodic structure, micro timing, accents, intonation, and final ritard.

  3. 2. Touching the Essence of Life : Haptic Virtual Proteins for Learning

    Författare :Petter Bivall; Anders Ynnerman; Lena A. E. Tibell; Matthew D. Cooper; Miriam Reiner; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haptics; Educational Research; Biomolecular Education; Life Science; JND; Just Noticeable Difference; Protein-ligand Docking; Haptic docking; Visualization; Haptic Transfer Functions; Volume Data Haptics; History Dependent Transfer Function; Log file analysis; Molecular Recognition; Force Feedback; Virtual Reality; Other information technology; Övrig informationsteknik;

    Sammanfattning : This dissertation presents research in the development and use of a multi-modal visual and haptic virtual model in higher education. The model, named Chemical Force Feedback (CFF), represents molecular recognition through the example of protein-ligand docking, and enables students to simultaneously see and feel representations of the protein and ligand molecules and their force interactions.

  5. 4. Source and Channel Coding for Audiovisual Communication Systems

    Författare :Moo Young Kim; Bastiaan Kleijn; Richard Heusdens; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Information theory; high-rate theory; source coding; channel coding; quantization; Telekommunikation; Telecommunication; Telekommunikation;

    Sammanfattning : Topics in source and channel coding for audiovisual communication systems are studied. The goal of source coding is to represent a source with the lowest possible rate to achieve a particular distortion, or with the lowest possible distortion at a given rate. Channel coding adds redundancy to quantized source information to recover channel errors. LÄS MER

  7. 5. Hard magnetism in novel glassy bulk Nd-Fe-Al

    Författare :Richardo J. Ortega-Hertogs; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis focuses on the magnetic properties of a newclass of Nd-based bulk glassyhard magnet, by measuring themagnetization in AC- and DC- fields up to 30 tesla, in thetemperature range 1 - 570 K. The main results of ourinvestigations and analyses in the framework of existing modelsare summarized as follows:1) The bulk glassy Nd-Fe-Al is found to be magneticallyisotropic, with hysteresis losses Wh?120 kJ/m3and maximum energy product (BH)max?2.
