Characterization and testing of novel single core phosphate fibers
(2019)
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 ...
Modeling of magnetic field distribution and optimization of a magnetron for magnetron sputtering technology
(2019)
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 ...
Optical properties of close-to-surface self-assembled InAs/GaAs quantum dots
(2018)
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 ...
Efficiency of upconversion process in lanthanide-doped host lattices
(2019)
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 ...
Additive manufacturing of medications and static light scattering analysis of mesoporous structures
(2019)
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 ...
Comparison of two modeling methods to describe the light emission from III-V nanowires
(2019)
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 ...
Numerical analysis of twist angle variations on the aerodynamic performance of NREL 5-MW wind turbine
(2019)
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 ...
Wind shear detection from Doppler weather radar data
(2019)
Intensive wind shear phenomena, such as downbursts and gust fronts, pose a hazard to aviation, and issuing local forecasts of them could improve safety and decrease costs. In this thesis, a methodology for detecting and ...
A risk model with renewal shot-noise Cox process
(2019)
Catastrophic events may lead to sudden changes in the claim arrival rate and as a result it is difficult to predict the likelihood for the occurrence of these events. These random fluctuation cannot be modeled as a homogeneous ...
Constitutive modeling of hyperelastic fibrous material
(2018)
This thesis will concentrate on the deformation of bodies from incompressible and compressible materials. The analysis is based on several approaches, the first approach is an analytical way. Here we will plan to consider ...
