1. 1. Starbursts at Cosmic Dawn : Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Olof Nebrin; [2022]
   Keywords : Cosmology; Galaxy Formation; Globular Clusters; First Stars; Dark Matter; Cosmic Dawn; Reionization; Ultra-Faint Dwarfs;

   Abstract : In the standard model of cosmology (ΛCDM) the first stars, star clusters, and galaxies are expected to have formed in short bursts of star formation in low-mass dark matter halos at high redshifts (). Up to this point, attempts to predict the properties and abundances of these luminous objects have made use of numerically expensive cosmological simulations. READ MORE

3. 2. Software tool for a configuration of a radiation detector for space applications

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Natálie Vítová; [2022]
   Keywords : radiation detection; sensor configuration; Space Dosimetry System Demonstrator; SpacePix Radiation Monitor; SpacePix-2-Lin-S;

   Abstract : The thesis deals with design of configuration software, ConfPix, for radiationdetecting sensor - SpacePix2. It describesdesign and implementation, as well as thetesting procedure. The software is implemented in Python, with Graphical UserInterface created using the Tkinter module for Python. READ MORE

4. 3. Creation of a Finite Element Model andSystem Analysis for the Low and HighFrequency Cryogenic Telescopes of theSpace Mission LiteBIRD

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Matias Rittatore Texeira; [2022]
   Keywords : FEM; FEA; mesh model; CMB; IRAP;

   Abstract : The Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection (LiteBIRD) is a Japan Aerospace Exploration Agency (JAXA)-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the early Universe, through the measurement of their imprint onto the polarization of the Cosmic Microwave Background (CMB). It is an international collaboration, with European Union (EU) operations being coordinated by France. READ MORE

5. 4. A Study on Fault Tolerance of Image Sensor-based Object Detection in Indoor Navigation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yang Wang; [2022]
   Keywords : Gazebo; YOLO; Object detection; Fault tolerance; Fault Injection; Network pruning; Gazebo; YOLO; Objektdetektering; Feltolerans; Felinjektion; Nätverk beskärning;

   Abstract : With the fast development of embedded deep-learning computing systems, applications powered by deep learning are moving from the cloud to the edge. When deploying NN onto the devices under complex environments, there are various types of possible faults: soft errors caused by cosmic radiation and radioactive impurities, voltage instability, aging, temperature variations, etc. READ MORE

6. 5. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Blahoslav Rataj; [2021]
   Keywords : Physics and Astronomy;

   Abstract : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. READ MORE
