  1. 1. Internal Cooling Design Using Multiphysics Topology Optimization

    Author : Jonas Lundgren; Carl-Johan Thore; Anders Klarbring; Jan-Erik Lundgren; Joe Alexandersen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis investigates topology optimization (TO) as a tool for designing optimal internal cooling configurations in components subjected to external hot gas streams. The work is motivated by the challenge of simultaneously considering objectives from multiple physics domains, and the rapid development of additive manufacturing (AM) in the industry, which makes it possible to realize highly complex TO designs.

  2. 2. Design of Functional Structures and Measurement Techniques for Electromagnetic Waves

    Author : Johan Lundgren; Teoretisk elektroteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional structures; frequency selective structures; polarization selectivity; metasurface; near-field measurements; antenna measurements; scattering measurement; power density; random media;

    Abstract : Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. READ MORE

  3. 3. Behind the Screen : -Internet-Based Cognitive Behavioural Therapy to Treat Depressive Symptoms in Persons with Heart Failure

    Author : Johan Lundgren; Peter Johansson; Tiny Jaarsma; Anita Kärner Köhler; Gerhard Andersson; Cecilia Fagerström; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cognitive behavioural therapy; Depression; Heart failure; Internet-based cognitive behavioural therapy; Patients’ experiences; Self-care; Telehealth; Depression; Egenvård; Hjärtsvikt; Internetbaserad kognitiv beteendeterapi; Kognitiv beteendeterapi; Patienters upplevelse; Telehälsa;

    Abstract : IntroductionThe prevalence of depressive symptoms in persons with heart failure is higher than in age- and gender-matched populations not suffering from heart failure. Heart failure in itself is associated with an unpredictable trajectory of symptoms, a poor prognosis, high mortality and morbidity, and low health-related quality of life (HrQoL). READ MORE

  4. 4. Making the Dead Alive : Dynamic Routines in Risk Management

    Author : Martin Lundgren; Åsa Ericson; Johan Holmqvist; Stewart James Kowalski; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Risk management; information security; routine; practice; asset identification; risk analysis; risk treatment; organizational aspects; Information systems; Informationssystem; Centrumbildning - Centrum för säkerhet i samhälle och kritiska infrastrukturer CISS ; Centre - Centre for Critical Infrastructure and Societal Security CISS ;

    Abstract : Risk management in information security is relevant to most, if not all, organizations. It is perhaps even more relevant considering the opportunities offered by the digitalization era, where reliably sharing, creating, and consuming information has become a competitive advantage, and information has become an asset of strategic concern.

  5. 5. Experiences of Interns and General Practitioners of Communicating with and Writing Referrals to the Radiology Department

    Author : Johan Kruse; Åsa Engström; Solweig Lundgren; Luleå tekniska universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Referral; communication; knowledge; radiology; General Practitioner; medical intern; Health Science; Hälsovetenskap;

    Abstract : The aim of this licentiate thesis was to describe the experiences of medical interns and general practitioners (GPs) communicating with and writing referrals to the radiology department. The referral is a major communication tool between medical professionals to establish an accurate diagnosis. READ MORE
