1. 6. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

   Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Elias Önerud; [2023]
   Nyckelord :Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

   Sammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER

3. 7. Combustibility study of resin for warm magnet coils used at CERN

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Juan Carlos Lopez Santiago; [2023]
   Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

   Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

4. 8. Comparison of muscle oxygen kinetics between occluded and non-occluded dynamic low-intensity exercise performed till failure : A quantitative study

   Kandidat-uppsats, Umeå universitet/Avdelningen för fysioterapi

   Författare :Natalie Smith; Josefine Johansson; [2023]
   Nyckelord :venous occlusion; muscle oxygenation kinetics; blood flow restricted exercise; ischemia; exercise failure; low-intensity strength training; Near-infrared spectroscopy;

   Sammanfattning : Aim: To examine local muscle oxygen kinetics when performing wrist extensions till failure in an occluded versus non-occluded state, to compare the perceived ratings of pain and local muscle exertion, and analysing presence of gender differences. Methods: Twenty-one healthy individuals (mean age 25,6±3. LÄS MER

5. 9. Deriving Spectral Maps from JWST Data : A Study of Enceladus’ Plumes

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Stephan Weissenböck; [2023]
   Nyckelord :Data Analysis; Enceladus; Plumes; Atmosphere; JWST; NIRSpec; IFU; Infrared spectroscopy; Dataanalys; Enceladus; plym; atmosfär; JWST; NIRSpec; IFU; infraröd spektroskopi;

   Sammanfattning : This study investigates the presence of water vapor plumes in the region south of Enceladus, a moon in the Saturnian system, through observations conducted by the James Webb Space Telescope. Enceladus is believed to harbor a subsurface ocean or localized water reservoir that gives rise to water geysers, expelling vapor into its tenuous atmosphere and outer space. LÄS MER

7. 10. Using the James Webb Space Telescope to Find Carbon Dioxide on Ganymede

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Olof Helgesson; Oscar Lundin; [2023]
   Nyckelord :;

   Sammanfattning : The aim of this bachelor's thesis is to search for CO₂ on Ganymede by studyingobservations taken by the James Webb Space Telescope and in doing so, create aprocessing pipeline for JWST data. The data is collected by JWST's Near InfraredSpectrograph instrument which is used for spectroscopy in the near infrared spectrum. LÄS MER
