  2. 1. Sound perception and design in multimodal environments

    Author : PerMagnus Lindborg; Anders K. Friberg; Daniel Västfjäll; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sound; perception; design; multimodal; environment; soundscape; music; listening; crossmodal; psychoacoustics; psychophysiology; personality trait; emotion; appraisal; aesthetics; colour; correlation; regression; classification; sonification; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of  methods, and integration of science and art. READ MORE

  4. 2. Regression methods in multidimensional prediction and estimation

    Author : Anders Björkström; Rolf Sundberg; Philip J Brown; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; regression; prediction; principal compnents regression; ridge regression; partial least squares; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : In regression with near collinear explanatory variables, the least squares predictor has large variance. Ordinary least squares regression (OLSR) often leads to unrealistic regression coefficients. Several regularized regression methods have been proposed as alternatives. READ MORE

  5. 3. Polycystic Ovary Syndrome and Pregnancy : Prenatal Exposures and Pregnancy Complications

    Author : Heiddis Valgeirsdóttir; Anna-Karin Wikström; Inger Sundström Poromaa; Theodora Kunovac Kallak; Marie Blomberg; Uppsala universitet; []

    Abstract : Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of fertile age. The aetiology of PCOS is not fully understood and might be affected by foetal exposures. Women with PCOS have an increased risk of pregnancy complications, but information on rare severe complications is scarce. READ MORE

  6. 4. Cold exposure and health : A study on neurological and vascular hand symptoms in northern Sweden

    Abstract : Background: Living in a cold climate is associated with several adverse health effects. The main purpose of this thesis was to describe cold exposure characteristics in northern Sweden, and investigate the associations between such exposure and the reporting of neurological and vascular hand symptoms.

    Abstract : Traumatic brain injuries are common (hospitalization incidence: 250-300 per 100.000 inhabitants/year) and a great majority of these injuries (80-85%) are classified as mild traumatic brain injury (MTBI/concussion). Many patients with MTBI (20-80%) suffer from subsequent persistent and often disabling symptoms. READ MORE
