Semi-automatic ontology construction
This thesis addresses the task of formalizing and implementing the process of semi-automatic ontology construction. We propose a theoretical framework for formalizing the ontology construction process. The process is described as a sequence of operators applied to the ontology. Several types of common operators are identified and each type is …
Normobaric hyperoxia: haemodynamic responses to acute and long-term exposure
The aim of the present thesis was to examine the effect of acute and long-term normobaric hyperoxic exposure on selected haemodynamic and haematological responses during resting and exercise conditions in healthy aerobically well-trained males. This purpose was evaluated in four separate studies, and each of them had a specific aim …
Ion beam analysis of geometrically structured samples
An experimental set-up for the detection of scattered projectile ions was constructed at the external (in air) beamline of the Microanalytical Center at the Jožef Stefan Institute. The system is composed of a detector for the analysis of back-scattered projectiles, casually called the RBS detector, a precise positioning system and …
Model for Monitoring and Assessment of a Public Health Care Network
It is hard to imagine the management of any system without monitoring it as a process of continuously gathering data and performing real-time analyses. In general, monitoring can improve the estimation of the current state, optimization of the business processes, identification of the critical elements and new opportunities, and prediction …
Radon in Kosovo
Radon and its progeny play an important role contributing to the dose of radiation which a person receives from all natural sources of ionizing radiation. This is one of the reasons why this problem has been of great interest, as a result of which an increased number of scientific works …
Synthesis and Characterization of Aluminium Foams
Aluminium foams are prospective class of cell materials that offer a variety of applications in fields such as lightweight structures or crash-energy management. Due to interesting combination of physical and mechanical properties, such as high stiffness at low density, high impact energy absorption, flame and heat resistance, sound absorption, aluminium …
Parameter Estimation of Nonlinear Dynamic Systems with Application to Failure Prognostics
This dissertation addresses the problem of parameter estimation of stochastic, discrete-time, state-space models from input and output data. This class of problems can be found in many modern engineering applications, where the relationships in the real world processes have to be inferred from the observed data and available prior knowledge. …
Phase slip phenomena and vortex dynamics in mesoscopic superconductors
We investigate the dynamics in one-dimensional (1D) and two dimensional (2D) mesoscopic superconductors in an external magnetic field using the time-dependent Ginzburg-Landau equations. We analyze the different transitions between metastable states and describe the creation of topological defects that occur as the phase of the Ginzburg-Landau order parameter makes finite …
Synthesis and characterization of perovskite nanostructures
Polycrystalline, BaTiO3 nanorods and SrTiO3 nanotubes were synthesized by the electrophoretic deposition (EPD) of a barium titanate sol and a strontium titanate sol into 2D ordered anodic aluminium oxide templates (AAO) with a subsequent thermal treatment and template removal. The BaTiO3 nanorods grown within the AAO template membranes had diameters …
Mercury in the Process of Cement Clinker Production and Emission Control
Mercury is a very toxic element. Due to its volubility it is present everywhere in the environment at ambient temperature. High temperature processes increased levels of mercury on the global scale. Global and European action plans were established to reduce mercury emissions and remove mercury from the environment. Cement plants …
