Heterogeneous catalytic conversion of non-edible lipid biomass to biochemicals
(PhD Thesis;2016:84, Doctoral thesis, 2016)The use of fuel increases consistently given the high demand for energy. This demand is mostly met by fossil fuels. Considering the uncertainties connected to fossil fuel reserves and the related natural effects of their ... -
NGS-based rDNA barcoding in fungal species identification and delimitation : limits, opportunities and relation to phenotypic HT FT-IR spectroscopy
(PhD Thesis;2017:28, Doctoral thesis, 2017)The abundance of ribosomal DNA (rDNA) in the yeast and fungal genomes derives from their multigene nature. During the last decade of the XX century, this DNA region has become very popular for the molecular characterization ... -
Prediction of spring wheat yield and grain quality with remote VIS-NIR spectroscopy and multivariate data analysis
(PhD Thesis;2012:26, Doctoral thesis, 2012)Along with an increasing population, both globally and locally, demands on agriculture increase. A sustainable increase in cereal yields is particularly focused and in this context, precision agriculture is becoming ... -
A study of potential energy sources used by cheese ripening bacteria
(PhD Thesis;2012:21, Doctoral thesis, 2012)Non-starter lactic acid bacteria (NSLAB) continue to grow in cheese during ripening even though lactose and its monosaccharide moieties (glucose and galactose (Gal)) are depleted. This indicates that the NSLAB are able to ... -
Optimisation of the coagulation process to improve plant availability of phosphorus in wastewater sludge
(PhD Thesis;2016:61, Doctoral thesis, 2016)Coagulation is used for the removal of colloids, particles and phosphates in wastewater treatment. The efficiency and economics of chemical coagulation, one of the most robust wastewater treatment processes, is critically ... -
Multiscale vibrational spectroscopy of pollen
(PhD Thesis;2016:10, Doctoral thesis, 2020-11-19)Pollen has a vital role in the reproduction of flowering plants by producing genetically diverse offspring via pollination. Environmental effects have strong influence on reproductive structures of plants, including on ... -
Information extraction from large point cloud data : a deep learning approach
(PhD Thesis;2020:25, Doctoral thesis, 2020)Recent advances in Light Detection and Ranging (LiDAR) sensors have led to an increasing amount of large scale point cloud data collections. The LiDAR sensors can capture the fine spatial details of a remote environment ... -
Analysis of land use / land cover change dynamics and underlying driving forces in the Lake Hawassa Watershed, Ethiopia, based on satellite remote sensing, GIS and field investigations
(PhD Thesis;2015:89, Doctoral thesis, 2020-11-04)Lake Hawassa Watershed, in the Central Rift Valley, is one of the most environmentally vulnerable areas in Ethiopia. The rapidly increasing population and vegetation clearance in search of farming and grazing land, firewood, ... -
The potential of molten salts as heat transfer media in fast pyrolysis of wood
(PhD Thesis;2015:1, Doctoral thesis, 2020-11-04)Growing energy consumption and greater environmental concerns have contributed to a need for more research on alternatives to fossil-derived products. Biomass such as wood is a potential source of renewable fuels and ... -
Scattering and absorption in nano- and microstructured media
(PhD thesis;2020:51, Doctoral thesis, 2020)When electromagnetic radiation interacts with objects of the same wavelength as the radiation, the objects can act as resonators and strong scattering effects appear. The goal of this PhD project has been to understand ... -
Chaos enhanced light trapping in optically thin solar cells
(PhD thesis;2020:3, Doctoral thesis, 2020)Photovoltaics is one of the most important sources of renewable energy. Solar cells with thin absorbing layers can be more cost-effective and leave a smaller environmental footprint than the current commercial technology. ... -
Environmental monitoring with ground-based interferometric radar systems
(PhD Thesis;2019:56, Doctoral thesis, 2019)The need for environmental monitoring is increasing with climate changes and natural resources exploitation, but the monitoring possibilities are also improving with the technological development enabling high spatial and ... -
Extracting movement patterns from geographical trajectory data
(PhD Thesis;2018:96, Doctoral thesis, 2018)Thanks to the recent advent of inexpensive positioning technologies, data about movement of various mobile objects are collected in rapidly growing amounts. Massive repositories of movement data require developing new data ... -
Rapid spectroscopic methods for predicting water-holding capacity in meat
(PhD Thesis;2018:3, Doctoral thesis, 2018)Water-holding capacity (WHC) is one of the most important quality traits in meat, and the main aim of this thesis was to examine the potential for rapid spectroscopic techniques to predict WHC in meat. A secondary aim was ... -
