1. 11. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories

   Författare :Imran Khan; Lars Håkansson; Ingvar Claesson; Josef Ström Bartunek; Gustavo R. Alves; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

   Sammanfattning : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. LÄS MER

3. 12. On the establishment of a data-driven approach to gravel road maintenance

   Författare :Keegan Mbiyana; Mirka Kans; Lars Håkansson; Jaime Campos; Ramin Karim; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road; condition assessment; conceptual modelling; condition classification; data acquisition; data-driven methods; field experiment; literature review; maintenance; visual assessment; Maskinteknik; Mechanical Engineering;

   Sammanfattning : Gravel roads are essential for economic development as they facilitate the movement of people, transportation of goods and services, and promote cultural and social development. They typically connect sparsely populated rural areas to urban centres, providing essential access for residents and entrepreneurs. LÄS MER

4. 13. In-line rheology of cement grouts - Feasibility study of an ultrasound based non-invasive method

   Författare :Mashuqur Rahman; Stefan Larsson; Ulf Håkansson; Thomar Dalmalm; Lars-O Ericsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Grouting is used in underground construction to reduce the water flow into tunnels and caverns and to limit the lowering of the surrounding groundwater table. Due to their wide availability and low cost relative to other materials, cement based materials are commonly used as grouts and, in this context, the rheology of the cement grout is an important factor.

5. 14. Science in Business Interaction : A Study of the Collaboration between CERN and Swedish Companies

   Författare :Susanne Åberg; Håkan Håkansson; Anna Bengtson; Alexandra Waluszewski; Lars-Erik Gadde; Uppsala universitet; []
   Nyckelord :Science-business interaction; resources; public procurement; technology transfer; technical development; big science; Business Studies; Företagsekonomi;

   Sammanfattning : The aim of this thesis is twofold; to gain and understanding of how CERN, the European Organization for Nuclear Research, interacts with industry; and to gain an understanding of how CERN can become a resource for industry. Both parts of the purpose also have implications for the issue of CERN’s usefulness to industry. LÄS MER
