  1. 1. Magnetic Fields and Induced Power in the Induction Heating of Aluminium Billets

    Author : Mark William Kennedy; Ragnhild E. Aune; Andreas Westermoen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction; heating; billets; coils; magnetic fields;

    Abstract : Induction heating is a common industrial process used for the reheating of billets before extrusion or forging. In this work the influence of the coil and work piece geometry, the effect of the electrical properties of the work piece, and the coil current and frequency, on the magnetic flux density and resulting work piece heating rates were studied.

  2. 2. Reaction Mechanisms and Dynamics in the Early Stage of High-κ Oxide Atomic Layer Deposition : Investigations by In Situ and Operando X-ray Photoemission Spectroscopy

    Author : Giulio D Acunto; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atomic layer depostion ALD ; high-k oxide; in situ and operando study; XPS; APXPS; Fysicumarkivet A:2022:D Acunto;

    Abstract : Atomic layer deposition (ALD) is an outstanding deposition technique to deposit highly conformal and uniform thin films with atomic precision. In particular, ALD of transition metal oxide layers from metal amido complexes and water finds its way in several technological fields, including green energy devices and in the semiconductor industry.

  3. 3. Mm-wave Radio Astronomy Instrumentation for the Onsala Space Observatory and SEST

    Author : Nicholas D. Whyborn; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mm-wave receiver; phase retrieval holography; focal plane imaging array; radio astronomy instrumentation; SIS mixer;

    Abstract : The thesis presents work done in developing instrumentation for mm- and submm-wave radio astronomy. The work described is in several fields. The greater part of the thesis is concerned with sensitive heterodyne receivers and in particular the cryogenically cooled mixers. In paper A the SEST telescope and its observing system are described. READ MORE

  4. 4. Information Systems Development for Emerging Public Sector Cross-sector Collaborations : The Case of Swedish Emergency Response

    Author : Kayvan Yousefi Mojir; Sofie Pilemalm; Stefan Holgersson; Johanna Sefyrin; Erik Borglund; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Information systems (IS) seem prevalent in modern societies and have resulted in the rapid digitalisation of different societal sectors. One application domain of IS is emergency response, which is responsible for delivering essential services to save lives and minimise environmental damage in both small , frequent and large-scale emergencies.

  5. 5. Excited-state dynamics of small organic molecules studied by time-resolved photoelectron spectroscopy

    Author : Ting Geng; Richard D. Thomas; Ben Whitaker; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time-resolved photoelectron spectroscopy; excited-state dynamics; organic molecules; kemisk fysik; Chemical Physics;

    Abstract : Ultra-violet and visible light induced processes in small organic molecules play very important roles in many fields, e.g., environmental sciences, biology, material development, chemistry, astrophysics and many others. Thus it is of great importance to better understand the mechanisms behind these processes. READ MORE
