   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Babak Rouhani; [2022]
   Nyckelord :Mechanics; Vibration; Modal analysis; Electronic equipment; Circuit board; Mekanik; Vibration; Modal analys; Elektronik utrustning; Kretskort;

   Sammanfattning : This paper presents an investigation of a problem discovered in electronic equipment where mechanical load was the leading cause of the issue. Finite Element Analysis is used to investigate vibration issues in soldering and components. Simulations are performed with ANSYS modal and random vibration package. LÄS MER

4. 8. CFD Optimization of Hydrofoiling Concept for A New Era of Sea Transports

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Anlun Li; [2022]
   Nyckelord :Optimization; Hydrofoil; FoilCart; Transportation; CFD; Optimering; Hydrofoil; FoilCart; Transport; CFD;

   Sammanfattning : The aim of this master thesis is to develop and optimize the main wing of a T-shaped hydrofoil for a small passenger vessel called FoilCart. The project is in collaboration with KTH Maritime Robotic Lab. The existing prototype of the hydrofoil is built by a company called ZPARQ\cite{Zparq}, but the efficiency of the main wing is not optimized. LÄS MER

5. 9. Development of a Level-0 Geoprocessing Platform for a Multispectral Remote Sensing Payload

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Sergio Santiago Bernabeu Peñalba; [2022]
   Nyckelord :Infrared imagery; VIS; NIR; LWIR; geoprocessor; geolocation; quaternions; Aistech Space; image processing; ORB; RANSAC; Sentinel; Landsat; Infraröda bilder; VIS; NIR; LWIR; geoprocessor; geolokalisering; kvarternioner; Aistech Space; bildbehandling; ORB; RANSAC; Sentinel; Landsat;

   Sammanfattning : This thesis presented an overview of the development of a geolocating algorithm as part of a geoprocessor for raw satellite imagery. This algorithm was devised for and limited by the specifications of a state-of-the-art multispectral telescope designed by Aistech Space, hosted onboard the Guardian spacecraft, which will observe Earth through the visible, near infrared, and thermal infrared bands of the electromagnetic spectrum.

7. 10. CFD validation of a new gas turbinestage design with experimental data

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Claudia Florentina Balan; [2022]
   Nyckelord :;

   Sammanfattning : Gas turbines are present in two energy-intensive sectors: aviation and energy production. Improving the efficiency of gas turbines has a huge impact on the reduction of CO2 in the atmosphere, therefore many research groups are studying innovative strategies to improve the performance of these turbines.
