Mercury in the Process of Cement Clinker Production and Emission Control

Author(s): Tanja Ljubič Mlakar (Author), Milena Horvat (Supervisor)

Year: 2011

Type: Doctoral dissertation

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 …

Nitrate migration in plant-soil-groundwater system

Author(s): Martina Šturm (Author), Sonja Lojen (Supervisor)

Year: 2011

Type: Doctoral dissertation

Nitrogen (N) is an essential nutrient for plant growth and one which has the greatest effect on the yield. Since effective indigenous sources are insufficient by far to support current levels of global agricultural outputs, N is intensively applied by farmers in the form of N-based fertilisers. However, excessive rates …

Development of analytical methods for speciation of organotin compounds in environmental samples using gas chromatography and mass spectrometry

Author(s): Mitja Vahčič (Author), Janez Ščančar (Supervisor)

Year: 2011

Type: Doctoral dissertation

Organotin compounds (OTCs) are the organometallic compounds with the most numerous applications. Today, it is more than 50 years of their intensive development and use. While they are highly useful chemicals they are also extremely toxic to a wide array of aquatic and terrestrial living organisms at very low concentrations. …

Ensembles for predicting structured outputs

Author(s): Dragi Kocev (Author), Sašo Džeroski (Supervisor)

Year: 2011

Type: Doctoral dissertation

In this thesis, we address the task of learning models for predicting structured outputs, which take as input a tuple of attribute values and produce as output a structured object. In contrast to classification and regression, where the output is a single scalar value, in our case the output is …

Test Infrastructure Design for ADC Cores in System-on-Chip

Author(s): Peter Mrak (Author), Franc Novak (Supervisor)

Year: 2010

Type: Doctoral dissertation

With the advent of System-on-Chip (SoC), intense research efforts are being carried out in order to find efficient practical solutions for testing deeply embedded, mixed-signal cores. Due to restricted access, a built-in self-test (BIST) of mixed-signal cores is in many cases a preferred alternative to a conventional test using external …

Measuring the probability for heterogenous recombination of hydrogen and oxygen atoms on surfaces of fusion relevant materials

Author(s): Aleksander Drenik (Author), Miran Mozetič (Supervisor)

Year: 2009

Type: Doctoral dissertation

This thesis presents studies of probability of heterogeneous recombination of oxygen and hydrogen atoms on surfaces of different types of carbon-based materials. The probability of heterogenous recombination is described with a quantity called recombination coefficient, which is defined as the probability that an atom which impinges upon a solid surface …

Nonequilibrium Dynamics of Charge and Collective Modes in Charge Density Waves Compounds

Author(s): Andrej Tomeljak (Author), Jure Demšar (Supervisor)

Year: 2009

Type: Doctoral dissertation

This thesis presents studies of ultrafast carrier relaxation dynamics in charge density wave (CDW) materials by means of femtosecond time-resolved optical spectroscopy. In these experiments, a femtosecond pump pulse excites electrons via interband transitions, thereby changing the optical properties of the material. The dynamics of relaxation processes is then recorded …

Occurrence, fate and removal of pharmaceutical residues in water treatment

Author(s): Tina Kosjek (Author), Ester Heath (Supervisor)

Year: 2009

Type: Doctoral dissertation

The presence of pharmaceutical residues in surface waters is an emerging environmental issue that provides a new challenge to treatment systems for potable water, wastewater and water reuse. Their principle pathways into the sewerage system are twofold: first, after being administered to patients they are normally excreted as various metabolites …

Text mining for discovering implicit relationships in biomedical literature

Author(s): Ingrid Petrič (Author), Tanja Urbančič (Supervisor), Bojan Cestnik (Co-Supervisor)

Year: 2009

Type: Doctoral dissertation

Data analysis with machine learning methods, when applied to large collections of text data, enables us to discover new knowledge. This knowledge, once put together, might describe the still unknown connections among phenomena and thus contribute to the formation of new hypotheses in different fields, medicine including. Also, connectivity and …

Monitoring of the product quality in manufacturing industries

Author(s): Jani Kleindienst (Author), Đani Juričić (Supervisor)

Year: 2009

Type: Doctoral dissertation

Unexpected production breakdowns and unpredictable defects in product quality remain critical problems in modern manufacturing systems. Usually occuring by no obvious exterior cause and often during periods of smooth production, they lead to production losses and reduced process availability, which results in lower profit rates. Conventional statistical methods of process …
