Model-based design is in many ways seen as a potential instrument in process industries due to the close link between the process and the model. In Växjö, the process industry of Lantmännen Reppe AB produces syrup. The syrup goes through an evaporation process in order to raise the sugar concentration. If the concentration gets to high the syrup turns solid, which can make the process a bit tricky
Climatic condition is what ultimately frames all ecosystems and is now undergoing dramatic change. IPCC models predict, in 100 years, a temperature increase between 2-5 ˚C and, as a consequence of warmer and wetter conditions, increased humic content in northern temperate freshwater systems. To study the impact of increasing temperature and humic content on shallow freshwaters a long-term outdoor
The main goal of this master thesis project was to take a manually controlled consumer quality quadrocopter and build the foundations which allows it to be autonomously controlled. This was achieved by introducing a exterior frame of reference through the use of a webcam coupled with image analysis algorithms. The position and rotation of the quadrocopter was identified, and several control struct

This Master Thesis describes the mathematical modeling of a Delta-3 robot actuated by motors and drive units developed by ELAU GmbH. A given model of the ELAU GmbH drive unit and motor is used when building the Delta-3 robot model including three drive units, one for each motor to be able to actuate the three upper arms. The Delta-3 robot model is divided into kinematics and dynamics parts. The ki
In dealing with calorimetry, safety aspects are very important. It is therefore very useful to be able to study a process before carrying out experiments on it. A computer model can then be very useful to save time and money. The purpose of this thesis was to construct a computer model of the Chemisens reaction calorimeter, in the modeling software Dymola. For the purpose of the modeling, a new Dy
Young people, who previously have been placed away from home in foster care, are from the political perspective, a particularly vulnerable group. This is a very general manner that previously placed young people live or has lived more volatile and turbulent, with changing within education and very poor self-management, What these peoples experience when they enter the independent adulthood is an a
Gambro is one of the biggest developers and manufactures of machines for hemodialysis treatments in the world. One component on their machines, the air level detector (ALD), has been identified to have a possibility to be further improved from usability perspective. The ALD is located at the front of the machine and has the function to hold the venous drip chamber in place and detect whether or no
The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. I will first simulate the influence, that the other planets have on
In this thesis we use theory of branch groups and profinite groups to find infinite finitely generated residually finite torsion-free groups whose profinite completions are pro-p. We achieve this by defining a property analogous to the congruence subgroup property of integer matrix groups, which most GGS-groups satisfy, and use this to show that the commutator subgroups of such groups has pro-p pr
The management of immigrants in the Basque region is an outlier among the administration of immigrants in democratic pollical communities. Basque autonomous Community government shows an unparallel handling of immigrants, particularly the irregular immigrants by institutionalizing policy that can diminish the effects of the restrictive Spain’s alien policy. The Basque policy has the objectives of
Single-domain antibody fragments, also called nanobodies, that target the spike glycoprotein of SARS-CoV-2 can potently neutralize the virus and prevent infection. In our first aim, we investigated whether their neutralization potency can be further increased by multimerization and generated multivalent constructs of a recently identified SARS-CoV-2 neutralizing nanobody, Ty1. We applied a novel m
MicroProteins are small, separately expressed parts of a larger protein and able to interfere with the full-length protein’s function. To enable modulation of hormone perception, microProteins were designed from the ethylene, cytokinin and gibberellin receptors. The protein isoforms designed to function as microProteins were overexpressed in Arabidopsis. Overexpression of a shortened gibberellin r
This study aims to investigate and model statistical properties of Bitcoin and other major cryptocurrencies. There were recent drastic changes in the level of Bitcoin prices as it moved from $740 in 2014 to $19,187 in 2017, and down to $3,830 in 2018. The current study aims to fill the gap in the analysis of cryptoccurencies, primarily Bitcoin returns statistical process. Specifically, the study s
