1. 11. Monte Carlo evaluation of static and dynamic 6FFF treatments - Evaluation of dose distributions calculated with AAA, Acuros XB, and Collapsed Cone (RayStation and DoseCheck)

   Master-uppsats,

   Författare :Alma Blombäck; [2023-02-23]
   Nyckelord :Medical physics; Monte Carlo; 6FFF; AAA; Acuros XB; DoseCheck; RayStation; DVH evaluation; flattening filter free;

   Sammanfattning : There are several benefits to removing the standard flattening filter and using so-called flattening filter free (FFF) treatments in external radiation therapy with photons. The main advantage is the possibility of significantly shortening the treatment time, de spite this FFF is not widely used yet. LÄS MER

3. 12. Drop-weight impact tests on reinforced concrete beams

   Master-uppsats, KTH/Betongbyggnad

   Författare :John Abdalnour; Milad Saliba; [2023]
   Nyckelord :;

   Sammanfattning : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. LÄS MER

4. 13. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

   Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Gustav Larsson; [2023]
   Nyckelord :organic solar cells; polymer; morphology; film; AFM;

   Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

5. 14. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Md Mamunur Rashid; [2023]
   Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

   Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

7. 15. Meadowscape : Bring health to ecological systems through actions in the agricultural landscape

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Arkitekthögskolan vid Umeå universitet

   Författare :Anna Östlund; [2023]
   Nyckelord :Actor-network theory; landscape ecology; agriculture; artifacts; patterns;

   Sammanfattning : The physical landscape is a patchwork of different physical and immaterial structures and networks built up through time, where nature and culture cooperate in processes of shaping the landscape. Since the first settlers in Sweden the grass meadow has taken a central part in the agricultural practices, but today little of this landscape remains. LÄS MER
