  3. 2. Selection of stimuli for listening tests by software-assisted ranking

    Författare :Jonas Ekeroot; Nicholas Zacharov; Luleå tekniska universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ljudteknik; Audio Technology;

    Sammanfattning : Within the academic field of audio technology, which is the context of this thesis, research questions related to various forms of perceptual audio evaluation of different types of audio systems are important and commonly encountered. Methods for systematic evaluations of listeners’ perceived audio quality, based on different experimental designs, have evolved over a time span of several decades and are collectively referred to as listening tests.

  4. 3. Predictive testing for contact allergy : comparison of some guinea pig and mouse protocols including dose-response designs

    Författare :Helen Wahlkvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :contact allergens; contact allergy; cumulative contact enhancement test; dose-response; evaluation; Freund s complete adjuvant test; guinea pig maximization test; local lymph node assay; mouse ear swelling test; patch test; predictive testing; statistical analysis;

    Sammanfattning : Contact allergy (delayed hypersensitivity) may develop as a result of skin exposure to contact allergens (haptens) and can lead to allergic contact dermatitis. The purpose of this study was to evaluate some predictive animal test methods for contact allergens. LÄS MER

  5. 4. Sport-sort : sorting algorithms and sport tournaments

    Författare :Hans Block; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Arrange a really short, thrilling and fair tournament! Execute parallel sorting in a machine of a new architecture! The author shows how these problems are connected. He designs several new tournament schemes, and analyses them both in theory and in extensive simulations. He uses only elementary mathematical and statistical methods. LÄS MER

  7. 5. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

    Författare :Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

    Sammanfattning : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. LÄS MER
