CNN-based ringed seal pelage pattern extraction
(2020)
The topic of this thesis is inspired by the conservation efforts of Saimaa ringed seals, which are in danger of becoming extinct with no appropriate actions. The work aims to develop a fur pattern extraction framework to ...
AFM investigation of the influence of relative humidity on the electrical potential of tin oxide films
(2021)
The influence of the relative humidity (RH) of the air on the electric potential of the materials' surfaces was investigated. Nickel-doped tin dioxide films were synthesized by magnetron sputtering in argon plasma. Atomic ...
Uncertainty quantification of FaIR climate model
(2021)
The FaIR model is a simple climate–carbon-cycle model. It is used for the estimation of temperature change caused by greenhouse gas emissions. The objective of the thesis was the conduction of sensitivity analysis of the ...
Estimation of Bełchatów Power Station emissions from TROPOMI nitrogen dioxide satellite observations
(2020)
The Bełchatów coal power station is the highest producer of nitrogen oxides, carbon dioxide, and sulphur dioxide emissions in Europe. The Tropospheric Monitoring Instrument (TROPOMI) aboard the Sentinel 5 satellite can ...
Instance segmentation of Ladoga ringed seals
(2020)
The wildlife photo-identification is an important issue today since it allows to identify and to track animals. It helps scientists to monitor the endangered species, although it is difficult to explore all the image ...
Spatiotemporal Matérn field modelling of Baltic Sea turbidity
(2021)
The state of the Baltic Sea has been a huge topic in recent years, at least in Finland. Algal blooms, eutrophication and environmental hypoxia have been a cause for worry for scientists. This thesis focuses on the modelling ...
Applicability of handheld Raman spectrometer for plant health monitoring
(2023)
In this study, Basil plants are monitored with a handheld Raman spectrometer. The objective is to find out if a handheld Raman spectrometer can be used as a monitoring tool for plant pollution and suggest a methodology to ...
Optimization of Signal-to-Noise Ratio for Fine Aerosol LIBS
(2023)
This thesis focuses on the optimization of the Signal-to-Noise Ratio (SNR) for fine aerosol Laser-Induced Breakdown Spectroscopy (LIBS). The objective is to investigate the impact of particle diameter and energy levels ...
