Observations of energetic particles and radio emissions during multiple coronal mass ejections
(Turun yliopisto, 2018-08-08)
This doctoral thesis studies the characteristics of solar energetic particle (SEP) events and solar radio bursts during multiple coronal mass ejections (CMEs). As well the influences of solar and interplanetary (IP) processes ...
Exploring connections between open quantum systems, relativity and complex quantum networks
(Turun yliopisto, 2020-12-05)
This thesis is a collection of works focusing on interrelations between the fields of special relativity, open quantum systems and complex networks. As each of the aforementioned fields encompasses a huge variety of topics, ...
Electrostatic instrumentation and measurements on powders and powder mixtures
(Turun yliopisto, 2019-05-25)
In the powder industry, such as the pharmaceutical or chemical industry, powder particles collide frequently with the surrounding surfaces and with other particles and become electrostatically charged in different processes. ...
Mass and radius constraints for neutron stars using X-ray timing, spectral, and polarization observations
(Turun yliopisto, 2020-12-11)
Neutron stars (NSs) are the most dense objects in the Universe that can be directly observed. The nature of the cold ultra-dense matter inside them is still unresolved, and determining the equation of state (EoS) of that ...
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). ...
Developing Exchange-Correlation and Kinetic Energy Functional Approximations for Density Functional Theory
(Turun yliopisto, 2018-01-13)
A nearly endless amount of technology relies on the understanding of the properties of matter and materials. Because the properties emerge from the motion of the electrons within matter, deepest and most accurate understanding ...
Activity and dust environment of comet 67P/Churyumov-Gerasimenko
(Turun yliopisto, 2018-06-01)
Comets are scientifically interesting objects for several reasons. Comets are among the most pristine objects of the Solar System, which can give us a way to directly study the imprints of the Solar System formation ...
Surface and bulk analysis of Sr2FeMoO6 thin films – Sr2FeMoO6 based spin valve
(Turun yliopisto, 2020-09-26)
This thesis deals with the analysis of Sr2FeMoO6 (hereafter refered to as SFMO) thin films. The material is a part of a versatile double perovskite structure family and exhibits potential attributes for basic scientific ...
Bl lac objects - view from the highest energies
(Turun yliopisto, 2020-06-16)
Relativistic jets launched by a super-massive black holes are among the most extreme particle accelerators in the Universe. BL Lac objects host a relativistic jet that points very close to our line of sight. They are the ...
