Development of SiC-based composite material for fusion application
Nuclear fusion offers a prospect of a safe, economical and environmentally friendly source of energy. For the advanced concepts of nuclear fusion, SiC-based fibre reinforced composites were proposed as a structural material for the first wall of the reactor vessel, enabling higher operating temperatures and efficiencies. Already developed techniques for …
Algorithms for Learning Regression Trees and Ensembles on Evolving Data Streams
In this thesis we address the problem of learning various types of decision trees from timechanging data streams. In particular, we study online machine learning algorithms for learning regression trees, linear model trees, option trees for regression, multi-target model trees, and ensembles of model trees from data streams. These are …
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 …
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 …
Development of analytical methods for speciation of organotin compounds in environmental samples using gas chromatography and mass spectrometry
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. …
Effect of ingested nanofibers and nanoparticles on digestive gland epithelium of a model test organism
Engineered nanofibers and nanoparticles are recognized as capable of inducing cellular perturbations according to the oxidative stress paradigm or by interacting directly with biological membranes. A number of authors in their investigations with the nanofibres and nanoparticles has reported the ability of nanofibers and nanotparticle to cause the different damage …
