Measurement of ultrahigh vacuum (UHV) and extremely high vacuum (XHV) is important in many advanced research and technology fields such as: equipment for surface analysis, particle accelerators, simulation of interstellar space, processing of advanced semiconductors, electron tubes, FE displays, etc. For traceable calibrations of UHV and XHV gauges we need …

In this doctoral thesis, we present the superhydrophilic effect on surfaces of three different materials, i.e. highly oriented pyrolytic graphite, graphite foil and graphite grain in polymer composite. In order to induce this complicated effect on the surface we used reactive oxygen plasma treatment. The plasma was created in glass …

This thesis presents the results of our experimental work in the field of new advanced materials such as liquid crystal elastomers (LCEs), electrocalorics and magnetoelectrics. In the first part, the conversion of thermal to mechanical energy is addressed in LCEs. The three important, newly discovered, chemical and physical parameters for …

This work had three aims. In the first part the influences of the sizes of the particles of barium ferrite (BaM) and their magnetic properties on the stability of the suspension were investigated. In second part the deposits were prepared by electrophoretic deposition (EFN) and the influence of particle size, …

Can a model constructed by machine learning or data mining programs be trusted? For example, it is known that a decision tree model can contain less-credible parts caused by pathologies in induction algorithms, noise and missing values in data, or simply because of the complexity of a domain. Such models …

Mechanical drives are the most ubiquitous items of equipment in almost all industrial branches. Wear, excessive operational loads or errors in assembly can cause premature unexpected failures resulting in partial or total production downtime, damaged equipment or even loss of lives. Proper condition monitoring of such equipment is therefore of …

The shift towards including human factors as part of system design has a direct impact on the security of the system. The users' misunderstanding of how a secure mechanism works usually results in security failures. People encounter security mechanisms daily, most often required to authenticate themselves using knowledge-based schemes such …

The research work presented in this thesis considers the development of new biocompatible surfaces that are able to control the adhesion of specific proteins responsible for the development of neurodegenerative diseases such as Creutzfeldt–Jakob, Alzheimer, Parkinson and Lewis body disease. Our approach was focused on problems prior to the detection …

In computer science, ontologies enable formalized knowledge representation. The goal of ontology extension is to correctly augment the existing ontology with new formalized knowledge (e.g., concepts, relationships etc.). This thesis addresses the ontology extension process based on text mining methods. News analysis is the application of the extended ontology. A …

Adaptation to altitude can enhance performance if the hypoxic dose and the frequency of the exposures are appropriate. While many hypoxic training modalities exist, the protocols utilizing short intermittent hypoxic exposures are gaining popularity. However, the effects of such novel hypoxic protocols on athletic performance are unclear. The aim of …
