Analýza sentimentu ve finančních zprávách
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 5. 9. 2024In the current era of information overload, monitoring associations and comprehending media and online news content, especially for investment purposes, is becoming increasingly demanding. This thesis addresses the challenge ... -
Dynamics of negative molecular ions
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 19. 9. 2024Phenomena occuring in low-energy electron-molecule collision have been the subject of intense study for the past several decades. Nonlocal resonance models proved to be a succesful tool for describing the nuclear dynamics ... -

U-based thin films: electronic structure and physical properties
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 17. 9. 2024Title: U-based thin films: electronic structure and physical properties Author: Oleksandra Koloskova Department / Institute: Department of Condensed Matter Physics, Faculty of Mathematics and Physics, Charles University ... -
Vliv Sc na mikrostrukturu a vlastnosti plynule odlévaných modelových slitin na bázi Al-Li
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 17. 9. 2024The solidification rate of high-strength aluminum alloys strongly impacts the cast structure. The size of eutectic cells could be reduced from several hundred micrometers, typical for ingot-cast materials, down to ... -
Broadband kinematic ground motion modeling of tectonic earthquakes
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 16. 9. 2024Broadband earthquake ground motion simulations represent a promising approach to seismic hazard analysis. After validation of synthetics against recordings, it provides us the possibility to dense up the information needed ... -
Kvalita aproximace stochastické dominance v závislosti na pravděpodobnostním rozdělení
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2022)Datum obhajoby: 2. 2. 2022This work focuses on measuring the quality of stochastic dominance approx- imation. A measure of non-dominance is developed to quantify the error caused by assuming that a stochastic dominance relationship holds even when ... -
Modern amplitude methods for fundamental interactions
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 13. 9. 2024In this work the toolbox of modern amplitude methods is used to examine a theory that has been mostly neglected quantum electrodynamics. At first we focus on maximum helicity violating (MHV) amplitudes in massless ... -
Study of the double-Dalitz decay of neutral pion at the NA62 experiment
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 13. 9. 2024The NA62 experiment at CERN represents leading physics research of rare kaon decays. The NA62 aims to measure the K+ → π+ νν decay branching ratio which is approximately 10−10 . Any significant discrepancy between the ... -
Study of jet suppression in heavy-ion collisions with the ATLAS experiment
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 13. 9. 2024Ultra-relativistic heavy-ion collisions are performed to generate and examine QCD matter at high temperatures, known as the quark-gluon plasma. This extraordinary state of matter is theorized to have been present in the ...
