1. 1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

   Författare :Doris Dijak; Elin Torstensson; [2023]
   Nyckelord :Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

   Sammanfattning : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

3. 2. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Harald Agelii; [2023]
   Nyckelord :Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

   Sammanfattning : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. LÄS MER

4. 3. Dynamic Modeling of Target's Cooling Systems

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Maximilian Cahlin; [2021]
   Nyckelord :Dynamic modeling; Modelica; Dymola; Fluid mechanics; Thermodynamics; Technology and Engineering;

   Sammanfattning : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. LÄS MER

5. 4. CHP process evaluation, optimization and troubleshooting in OpenModelica

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

   Författare :HANNES WISTRAND; [2017]
   Nyckelord :;

   Sammanfattning : As an important part in creating a sustainable energy sector the most prevalent sources of energy production must be in the forefront of being both reliable and effective. In Sweden district heating is utilized in more than half of all households and must therefore be subject to the same scrutiny and analyses as other energy producing technologies. LÄS MER

7. 5. Studies of pyridine in water clusters with synchrotron radiation and 3D momentum spectrometry

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Författare :Benjamin Bolling; [2017]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : By using the site-selectivity enabled by synchrotron radiation, we can choose the ionization site on a molecule. Core-ionization can result in that the molecule dissociates into charged (and uncharged) ions. With mass spectroscopy, the dissociated fragments’ mass-over-charge can be identified in a time-of-flight spectrum. LÄS MER
