  1. 1. Influence of building envelope on indoor air quality: Field measurements, analysis, and method development related to indoor odors

    Författare :Fredrik Domhagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material emissions; VOC; odor; ventilation; indoor air quality;

    Sammanfattning : The ventilation system should provide occupants with fresh air while removing excess pollutants from the building. However, increasing ventilation may inadvertently draw more pollutants into the occupant area or prove ineffective in altering emission rates from building materials and furnishings. LÄS MER

  3. 2. The alluring nature of episodic odor memory : Sensory and cognitive correlates across age and sex

    Författare :Christina Blåvarg; Peter Juslin; Mats J. Olsson; Steven Nordin; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; Age; Sex; Episodic odor memory; Odor identification; Recollective experience; Hedonic; Healthy; Adults; Psychology; Psykologi;

    Sammanfattning : Episodic memory for olfactory information is still relatively uncharted. The overall purpose of this thesis is to investigate the sensory and cognitive causes of the well-established age-related decline in olfactory episodic odor memory and of the age-independent sex difference in olfactory episodic memory.

    Sammanfattning : This thesis deals with machine learning techniques for the extraction of structure and the analysis of the vertebrate olfactory pathway based on related methods. Some of its main contributions are summarized below. LÄS MER

  5. 4. Critical Factors for digital Printing on Paperboard : Runnability, Functionality & Print Quality

    Författare :Veronica Gidlöf; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital printing; paperboard; electrophotography; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

    Sammanfattning : More than ten years ago, the first digital print units were introduced on the market and since then, the technology has developed rapidly. Digital printing on packaging material is, however, a rather new area, but a probable prediction is that there soon will be a market need for board products that can be used for digital printing.

  7. 5. Perceptual integration of odor mixtures

    Författare :Malin Schütze; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Virtually all perceptions of environmental odors are based on an integration process of many volatile components, in many cases hundreds of components. By investigating the perceptual dimensions in this perceptual integration process and how it is affected by the neurophysiology of the olfactory system we can begin to understand the nature of complex odor perception.
