Model metal-oxide electrocatalysts for energy conversion
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 14. 11. 2024The development of novel (electro-)catalysts is commonly based on a trial-and-error approach without detailed understanding of the catalytic processes at the atomic scale. Reaching such understanding would be desirable, ... -
Adsorption geometry and protective properties of phenylphosphonic acid on inorganic materials
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2025)Datum obhajoby: 28. 2. 2025The thesis investigates the adsorption and thermal stability of phenylphosphonic acid (PPA) on Cu(111) and cerium oxide films of different stoichiometry, composition, and morphology. A combination of advanced analytical ... -
Understanding the catalytic and gas-sensing properties of metal oxide nanostructures with advanced surface science techniques
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2025)Datum obhajoby: 28. 2. 2025Title: Understanding the catalytic and gassensing properties of metal oxide nanostructures with advanced surface science techniques Author: Lesia Piliai Department: Department of Surface and Plasma Science Supervisor: ... -
Theory and numerical solution of traffic models
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2025)Datum obhajoby: 27. 5. 2025In this thesis, we describe a numerical technique for the solution of macroscopic traf- fic flow models on networks. On individual roads, we consider the standard Lighthill- Whitham-Richards model which is discretized using ... -
The role of rheology and water in the deformation of subducting slabs
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 8. 11. 2024The process of subduction, a key driver of plate tectonics, has been intensively studied over the past few decades. Understanding the complex mechanisms that control subduction dynamics is essential for comprehending slab ... -

Integrated nested Laplace approximation
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2025)Datum obhajoby: 4. 2. 2025This work explores Bayesian inference for Generalized Linear Mixed Ef- fects Models (GLMMs), essential tools for analyzing hierarchical and group- structured data. While traditional Markov Chain Monte Carlo (MCMC) methods ... -
Detekcia oblakov na snímke oblohy, analýza a vylepšenie metodík
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2025)Datum obhajoby: 11. 2. 2025There are many algorithms available for the cloud detection from ground-based images. These typically differ in the image pre-processing steps and the type of segmentation. Each of these algorithms has been developed for ... -
Vysvětlitelná evaluace generování textu založená na velkých jazykových modelech a chybové analýze
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2025)Datum obhajoby: 4. 2. 2025Traditional metrics for evaluating natural language generation (NLG) often struggle to capture linguistic complexity or align with human judgment. Recently, approaches based on large language models (LLMs) have been proposed ...
