In order to make the hydrogen economy fully sustainable, renewable resources have to be employed for its production. Simulation models, developed with Aspen Plus to calculate mass and energy balances, will be used to integrate the process steps necessary to produce pure hydrogen from biomass in a 2-stage fermentation process. The main challenge is the reduction of water and heat demand connected t
Fermentation of biomass residues and second generation biomasses is potentially a way to enable a sustainable production of hydrogen. Simulation models which calculate mass and energy balances, developed with Aspen Plus (R), are used to integrate the process steps necessary to produce pure hydrogen from biomass in a 2-stage fermentation process. Process and heat integration are introduced to reduc
The number of copies of DNA in human cells can be measured using array comparative genomic hybridization (aCGH), which provides intensity ratios of sample to reference DNA at genomic locations corresponding to probes on a microarray. In the present paper, we devise a statistical model, based on a latent continuous-index Markov jump process, that is aimed to capture certain features of aCGH data, i
Biomass gasification is one of the alternatives to producing liquid fuels and chemicals from biomass residues. The gas produced in gasification contains CO, H2, H2O, CO2, light hydrocarbons and tars. Depending on the gasifier type, operating conditions and fuel, the light hydrocarbons can contain as much as 50 % of the total energy contents in the gas. The gas also contains catalyst poisons such a
The utilization of industrial side streams for generating value has always been of interest, but in today's society, with a high focus on the circular economy, it is becoming increasingly important. Lime mud (whose major component is calcium carbonate, CaCO3) is a low-value by-product of the pulp and paper industry that is generated in considerable amounts during the causticizing process.

We investigate the performance of concatenated coding schemes based on Faster Than Nyquist(FTN) signaling over the AWGN channel. We test both serial and parallel concatenations. In serial concatenation the FTN signaling is considered as the inner encoder and the outer code is a rate b/c convolutional code. In parallel schemes we use two parallel Gaussian channels and transmit FTN pulse trains in b
The automotive industry in Europe has been forced to develop new solutions for the vehicles in order to fulfill the emission standards set by the European Commission according to European Emission Standards (Euro). The latest, Euro 6, involves new demands on continuous audits of emissions during a vehicles lifecycle. The standards are legislated and without approval a manufacturer may lose its lic
We investigate faster-than-Nyquist modulation based on short finite pulses over the AWGN channel. We consider several pulse shapes and compare their information rates for several system setups. We compare the effect of increasing the alphabet size versus of increasing the signaling rate. The outcome is that for these pulses the FTN symbol rate is of greater importance than the alphabet size. Final
Geospatial data is becoming increasingly important as artificial intelligence develops rapidly, creating new opportunities in the field of Geographic Information Systems. The thesis investigates the possibility of establishing a method to automatically calibrate a network camera’s geolocation and heading direction by using a camera view image and its corresponding satellite image. The aim is to lo
