1. 1. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Robert Petersen; [2023]
   Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

   Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

3. 2. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

   University essay from Umeå universitet/Institutionen för fysik

   Author : Malin Gelfgren; [2023]
   Keywords : ;

   Abstract : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. READ MORE

4. 3. Extension of the Mission Timeline Simulator with Modern Optimization Capabilities

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Flavia Pérez Cámara; [2022]
   Keywords : Optimization; timeline; simulator; matlab; control;

   Abstract : The Advanced Telescope for High-Energy Astrophysics (ATHENA) has been selected as the second large (L-class) mission designed to address the Cosmic Vision science theme “The Hot and Energetic Universe”. The European Space Agency has produced a Mission Observation Plan which contains objectives and constraints of the mission. READ MORE

5. 4. System:Forest

   University essay from KTH/Arkitektur

   Author : Samira Hedberg Ibáñez; [2022]
   Keywords : Kronby; Forest; tree; Wood; Design for Deconstruction; Deconstruction; Dissassemble; Reassemble; Architecture; System; construction; Iso timber; CLT; Gluelam; Cabin; House; Gazebo; Complementary building;

   Abstract : What I have tried to do in this project is to come up with a system of building that gives the building and the materials within, a chance for a longer life. A system that does not only make it easier to change the layout on the inside, but also makes it easier to disassemble the entire structure with minimal damage to the materials and the surroundings.

6. 5. A concept to evaluate dynamic daylight glare

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Efthymia Eirini Tsianaka; [2018]
   Keywords : glare; daylight; zonal; long-term; adaptation possibility; TPG; STG; directional glare; weighting system; dynamic; visual comfort; fenestration system; Arts and Architecture; Technology and Engineering;

   Abstract : A method towards a dynamic daylight glare evaluation in the early stage of design was developed in this thesis, using existing glare metrics under multiple observer positions and gazes. The results pointed out that it is possible for a zonal characterization regarding glare sensation to be achieved with the combination of multiple existing metrics and a weighting system, named the adaptation possibility.
