1. 6. Analysis of atmospheric influences on ratio thermography for solar tower systems

   University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

   Author : Albin Englin; [2022]
   Keywords : Concentrated solar power; Ratio thermography; Shortwave infrared; Gray body assumption; Atmospheric compensation;

   Abstract : The knowledge of temperature and emissivity of the receiver are both critical for a solar tower power plant, in order to guarantee an efficient operation of the thermal receiver on the one hand, while monitoring any degradation of the receiver coating on the other hand. To make these measurements, a new thermographic system is currently being developed, using a multispectral camera working in the short wavelength infrared spectrum. READ MORE

3. 7. Blind Channel Equalization for Shortwave Digital Radio Communications

   University essay from Linköpings universitet/Reglerteknik

   Author : Tomas Busk; [2020]
   Keywords : Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

   Abstract : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

4. 8. Influence of microstructure on surface characteristics in cold-deformed stainless steel tubes

   University essay from Lunds universitet/Materialteknik

   Author : Fredrik Ottenklev; [2019]
   Keywords : Cold deformation; surface roughness; strain; microstructure; austenitic stainless steel; grain rotation; Technology and Engineering;

   Abstract : Cold deformation of metals is known to induce roughness on their free surface. In some of the processing equipment of Tetra Pak processing systems, tubes of austenitic stainless steel 316L are used. During the production of this processing equipment, such tubes are occasionally cold-deformed. READ MORE

5. 9. Cloud Observations at a Coastal site – Analysis of Ceilometer Measurements from Östergarnsholm, Sweden

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Aron Stenlid; [2019]
   Keywords : Ceilometer; Stratocumulus; cloud base height; LCL; DLS; upwelling; cloud cover;

   Abstract : In this study, four and a half months of ceilometer data from Östergarnsholm are used to analyze cloud related to processes in the boundary layer. Measurements are divided into two categories, which are defined by wind direction: a continental and a marine sector. READ MORE

6. 10. Climatic effects of changes in radiative forcing due to clear-cutting in Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Iris Muzic; [2019]
   Keywords : Physical Geography and Ecosystem Science; land-cover change; ICOS; albedo; carbon dioxide; radiative forcing; clear-cutting; Earth and Environmental Sciences;

   Abstract : Land cover conversion affects climate by imposing changes in the surface properties and carbon dioxide fluxes. Forest management programs often disregard that modification in surface albedo influences the exchange of energy and climate sensitivity. READ MORE
