This work is devoted to the study of novel optical fibers doped with Er3+ ions. Fibers were drawn from the phosphate glasses with different compositions. One of the optical fibers was drawn from a heat-treated preform in ...

Current work focuses on applications of computer simulations for design optimization of a magnetron sputtering source. In order to perform the optimization, a program was written that allows to model all stages of magnetron ...

Quantum dots are novel semiconductor nanostructures that show great potential to be the future of a wide range of nanoscale optoelectronic device applications like photodetectors, solar cells and lasers. Self-assembled ...

The main target of this work was to investigate the influence of the host matrix on the upconversion luminescence. The quantum yield was used as a measure of luminescence efficiency. For this, a reliable and sensitive ...

Multiple samples of graphite were given for measurement for the study. Three of them wereperforated, and two of them were pure to give a reference point to the perforated samples.The purpose was to measure and determine ...

Kandidaatintyön tavoite oli tutustua kvanttitietokoneeseen ja sen mahdollisiin sovelluskohteisiin etenkin optimoinnin parissa. Kandidaatintyössä kartoitettiin erilaisia kvanttitietokoneen toteutusmahdollisuuksia, kuten ...

The main focus of the project was on the development of a method for three-dimensional printing of matrixes of drug carriers. For implementation, a wide instruction was applied, because for the solution of problems it was ...

The aim of this thesis was to get acquainted with and compare the performances of several label fusion algorithms experimentally using retinal image segmentations. Because the initial retinal image data could not be used ...

This work contains information about two different approaches to model the emission of radiation from semiconductor nanowires. Modeling part was performed with the COMSOL Multiphysics software to solve Maxwell’s equations ...

The study of wind turbine aerodynamics is crucial to get the best power output from the available wind flow. This thesis investigate the aerodynamics effect of twist angle variation of the blade on the power output of the ...
