  1. 16. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

    University essay from

    Author : Ali Amena Hussain; [2022-03-09]
    Keywords : Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

    Abstract : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

  3. 17. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

    University essay from KTH/Teknisk mekanik

    Author : Nikolaos Bozikis; [2022]
    Keywords : Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

    Abstract : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. READ MORE

  4. 18. Process monitoring of turbine blades : Monitoring of blade tip clearance using eddy current sensors

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Keywords : Blade tip clearance; Blade tip timing; Eddy current sensor; Turbine monitoring; Maintenance.; Bladtoppspel; Bladvibrationer; Eddy current sensorer; Turbinövervakning; Underhåll.;

    Abstract : This thesis has been a collaboration between the Royal Institute of Technology (KTH) and Siemens Energy which invest in the research facility at KTH. The objective was to investigate the use of eddy current sensors in real-time monitoring of turbine blades. READ MORE

  5. 19. An Application of Channelized Hotelling Observer for Optimization of CT Scanning Protocols

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Yuting Wang; [2022]
    Keywords : ;

    Abstract : Low contrast detection tasks like detecting a lesion in an image are of high importance in medical image diagnostics. If performed by human observers, the results are subjective, and the reproducibility is limited. READ MORE

  6. 20. Development of CFD method to model thermal properties of laminates in a truck cab : Modeling solids and HVAC performance

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aniruddh Mohan; [2022]
    Keywords : CFD; Conjugate heat transfer; HVAC; Shell modeling;

    Abstract : The study of Heating, Ventilation and Air Conditioning (HVAC) system performance is important to understand its energy consumption, especially for electric vehicles. The purpose of this thesis is to develop a methodology to simulate the flow within the Scania S20H cab while also capturing the thermal properties of the fluid and solids within the cab. READ MORE
