1. 1. Flash Pulse Thermography Measurements of Coat Thickness

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Alexander Häggkvist; [2023]
   Nyckelord :Flash Pulse Thermography; Power Function; Dynamical Thermal Tomography;

   Sammanfattning : The application of varnish, metal coats, and paint is a common practice for modifying or enhancing material properties. Metal coats are frequently used as protective layers against corrosion, heat, and wear, while also influencing characteristics like conductivity, weight, and production costs. LÄS MER

3. 2. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Sara Lenman; Sofia Blaad; [2023]
   Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

   Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

4. 3. När militarisering mötte välfärdsstat : Beredskapsplaneringen av svensk sjukvård 1950–1985

   Master-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

   Författare :Gerhard Skriveus; [2023]
   Nyckelord :Civil defence; Cold war; Healthcare; Militarization; Military medicine; Organization; Planning; Sweden; Total defence; War medicine; War planning; Warfare; Welfare; Welfare state;

   Sammanfattning : This paper studies when warfare meets welfare in the Swedish contingency planning of healthcare in war during the period 1950 to 1985 with the aim of analysing how the planning changed, what caused these changes and how this can be linked to societal changes in the post-war Sweden. The analysis is carried out with the help of a self-adapted stakeholder model where first the change in planning and management is analysed and then seeks causal explanations for the key changes based on three military and three civilian drivers.

5. 4. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zhenyu Li; [2023]
   Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

7. 5. Creativity Management in Creative Organizations : The Economic versus Creative Perspective

   Kandidat-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

   Författare :Kayla Holliday; Mårten Brorsson; [2023]
   Nyckelord :creativity; creativity management; film and business; conflict management; creative organizations; creative versus economic perspective; dual executive leadership;

   Sammanfattning : For businesses that rely on creativity for their success, its effective and thought-out management is necessary for the entity to thrive. The field of creativity management has emerged as a result, highlighting the employment of a ‘creative climate,’ motivational tools, and an appropriate organizational structure as essentials for the asset’s optimization (Dubina, 2013, Sternberg and Lubart, 2004, Tonnquist, 2018, Csikszentmihalyi and Wolfe, 2014, Karambayya and Reid, 2009).
