  2. 1. Interest and Engagement: Perspectives on Mathematics in the Classroom

    Author : Rimma Nyman; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interest; engagement; mathematics; introduction to algebra; TDS; years 6-9; video analysis; interviews;

    Abstract : The aim of this research project is to illuminate interest manifested as student engagement in mathematics in years 6-9. In particular, the studies capture how engagement is recognised by teachers and researchers and what didactical strategies the teachers use to engage students in an introduction to algebra.

  4. 2. Benefits and risks with digital dermoscopy and teledermoscopy

    Author : Johan Dahlén Gyllencreutz; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; melanoma; non-melanoma skin cancer; teledermoscopy; dermoscopy; teledermatology; e-health;

    Abstract : The increasing incidence of malignant melanoma and non-melanoma skin cancer (NMSC) makes it necessary to optimize the management of patients with suspicious skin lesions, from triaging, to establishing a diagnosis and planning treatment. The purpose of this thesis is to investigate the use of teledermoscopy (TDS) as a way of achieving such an optimization, as well as to study safety aspects of digital dermoscopy and teledermoscopy while pointing out risks and pitfalls so that they can be avoided.

  5. 3. Dynamic Security Region Assessment

    Author : Marina Oluic; Mehrdad Ghandari; Bertil Berggren; Jovica V. Milanovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parametrization; power system transient stability; security boundary; short-term voltage instability; Voltage Impasse Region VIR ; parametrisering; spänningsimpassregion VIR ; spänningsinstabilitet; säkerhetsgräns; transient stabilitet i kraftsystem; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Among a wide variety of topics that are covered by Dynamic Security Assessment (DSA), maintaining synchronous operation and acceptable voltage profiles stand out. These two stability categories are mostly jeopardized in the seconds after a large contingency occurs. READ MORE

  6. 4. Phase retrieval method for quantitative terahertz spectroscopy in reflection geometry

    Author : Kasturie Jatkar; Stefano Bonetti; Magnus Berntsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terahertz; reflection; THz spectroscopy; InSb; Physics; fysik;

    Abstract : Terahertz time-domain spectroscopy (THz-TDS) is a reliable technique used for studying the complex optical properties of materials. Its frequency range makes it suitable for detecting low-energy collective excitations such as phonons, magnons, and plasmons. THz-TDS in transmission geometry has gained much attention over the years. READ MORE

  7. 5. Periarticular changes in association with osteoarthritis in the hip, knee or shoulder

    Author : Mustafa Ibrahim; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Tendinopathy; Bone mineral density;

    Abstract : The aim of this thesis was to evaluate the presence of degenerative changes in the periarticular tendons in association with osteoarthritis (OA) in the hip, knee or shoulder. Moreover, changes in bone mineral density (BMD) in the hip, spine and calcanei were investigated after total hip arthroplasty (THA). READ MORE
