The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. The common theme for all the work presented is the pyParticleEst software framework, which has b
The transition quadrupole moments Q(t) for the superdeformed band in Ca-40 have been determined through thin-target Doppler-shift attenuation analyses. A best-fit value of Q(t)=1.30+/-0.05 e b is obtained when a single value is assumed for the entire band. Fitting separate quadrupole moments for in-band transitions decaying from the high-spin states and the presumably admixed low-spin states resul
The influence of different dryer fabrics on the contact coefficient has been studied experimentally under various conditions. A bench-scale drying apparatus, in which the fabric could be fixed at variable tensions, was used in the experiments. A technique for measuring the heat flux and surface temperatures of the paper sample and the hot surface was developed. Three paper grades were used in the
A novel calcium-independent serine protease from an alkaliphilic bacterium, Nesterenkonia sp. AL20, has been purified and crystallized at 296 K using sodium formate as the main precipitant. This enzyme is optimally active at pH 10, exhibits high stability towards autolytic digestion and its stability is not affected by the presence of EDTA or detergents. The triangular prism-shaped crystals diffra
Aims and objectives. The aim of the study was to investigate the quality of life and related factors among older people who are in pain and in need of help to manage daily living. Background. To intervene against the low quality of life in nursing care knowledge about factors affecting it is needed and this is especially important for vulnerable people such as those who suffer from pain and who a
Varje år dör runt 40 till 60 arbetare på svenska arbetsplatser. För att sätta det i kontext kan nämnas att 43 människor miste livet i dödligt skjutvapenvåld år 2018. Arbetsplatsolyckor inträffar trots att det inte sällan finns tydliga varningssignaler och möjligheter till säkerhetsåtgärder, varför ett flertal sannolikt hade kunnat förhindras. Detta arbete undersöker arbetsmiljöbrott genom en rättsEach year around 40 to 60 workers die at Swedish worksites. In a wider context, it can be mentioned that 43 people lost their lives due to lethal use of firearms in 2018. Workplace fatalities occur even though there are often clear warning signs and possibilities of safety measures, which is why a great number of workplace fatalities likely could have been prevented. This thesis examines workplace

Bioenergy with Carbon Capture and Storage (BECCS) is a largely promoted, but also heavily contested solution to the problem of climate change. Whilst removing carbon from the atmosphere, it potentially leads to detrimental side effects. This thesis provides guidance for NGOs, industry and policymakers in Germany and the wider EU context on how to assess the sustainability of BECCS implementation p
Aim: To examine the incidence of post-lumbar puncture headache (PLPH) in patients admitted for cognitive disturbances. Methods: The incidence of PLPH and other general (subdural hematoma, meningitis, encephalitis) or local (local pain, spinal hematoma, local infection) complications was evaluated in 1,089 consecutive patients (aged 23-89 years) who underwent lumbar puncture as a part of the routin
Amelogenin, a matrix protein involved in biomineralization of enamel, can self-assemble to form nanospheres in a pH-dependent manner. Nucleic acids (single-stranded, double-stranded, and plasmid DNA, as well as RNA) could be co-precipitated with amelogenin, demonstrating a strong binding of nucleic acids to amelogenin. The amounts of co-precipitated nucleic acids were analyzed and binding levels u
According to traditional trade theory, trade reduces inequality between the rich and the poor. However, since the beginning of the 1980s, a constantly rise in within-country inequality has been observed in many developed and developing countries. With the rapidly increasing globalization during the same period in mind, a natural question to ask is whether the two phenomenon are linked. In this pap
The European Corn Borer (ECB) has the potential to markedly reduce the yield from corn plants and in turn affect the economy of farmers. The human world population is increasing and there is consequently an increased number of mouths to feed on a limited area, the Earth, and this makes this an important topic to study. It is thus important to find out whether the ECB likely will be an important pe
