Particle observations in near-earth space: Design and verification of particle instruments for CubeSat experiments
(Turun yliopisto, 2021-12-15)
This doctoral thesis presents the design, simulation, and calibration of two instruments developed to study energetic charged particles in low-Earth orbit. The near-Earth energetic charged particle populations include ...
Investigation of properties of solar energetic particles and geomagnetic storms related to coronal mass ejections
(Turun yliopisto, 2019-12-19)
Solar energetic particles (SEPs) and geomagnetic storms related to coronal mass ejections (CMEs) are a major research topic in solar-terrestrial and geospace physics. Solar energetic particles and coronal mass ejections ...
Measurement simulability and incompatibility in quantum theory and other operational theories
(Turun yliopisto, 2021-06-17)
Quantum theory is a particularly important instance of an operational theory.By looking at quantum theory from the perspective of more abstract operational framework one is able to study its properties in a wider context. ...
Ab initio investigations of the durability of iron alloys and titanium
(Turun yliopisto, 2019-06-14)
In this ab initio work the oxidation of Fe-Cr, Fe-Al, Fe-Cr-V and Fe-Cr-Al, and the elasticity of Fe-Cr-Al alloys and titanium were investigated. The computational method used was Exact Muffin-tin Orbitals method (EMTO). ...
Empirical modelling of solar energetic particles
(Turun yliopisto, 2021-06-28)
Solar energetic particles (SEPs) are an important component of space weather. They pose a serious radiation hazard to electronic equipment and biological organisms in space. They are produced in explosive events such as ...
Low bandwidth manganite (Gd, Ca)MnO3 for future memristor devices
(Turun yliopisto, 2022-05-21)
Particle decay in the early universe
(Turun yliopisto, 2020-12-12)
Particle decay processes have deep and profound implications in cosmology and especially on various early universe particle processes. Common decay rates, which may be experimentally verifed e.g., in particle accelerators, ...
YBCO superconductor on buffered metallic tapes for coated conductor based applications: Modifying the pinning landscape for improving the critical current densities
(Turun yliopisto, 2021-09-25)
High temperature YBa2Cu3Oz<sub>6+x</sub>superconducting films are deposited on top of differently fashioned buffered metals to enhance the critical current density and its isotropy for coated conductor applications. The ...
Statistical properties of solar energetic proton events
(Turun yliopisto, 2023-05-30)
The Sun is the source of several different kinds of high-energy particles that are most prominently released in sudden large eruptions, known as solar energetic particle events. These particles, which escape the Sun and ...
Determination of absorbed dose by radiophotoluminescence dosimetry and Monte Carlo simulations
(Turun yliopisto, 2023-04-21)
Radiation therapy (RT) utilizes the harmfulness of ionizing radiation for good, with the goal of destroying cancer cells without damaging too much healthy tissue. Dosimetry is always needed to achieve this goal. Dosimetry ...
