The goal of this master thesis has been to implement adaptive PI-control of two air flow heaters in an air sterilization module. This is done by modeling the module and using the information from the model to estimate the dynamics of the heaters. The idea of this thesis is to implement adaptive control with as simple control structures and tuning algorithms as possible, to keep it as generalized

The cost of healthcare in Sweden has risen steadily since the beginning of the 21st century and one of the major contributors to the increase are chronic diseases. Chronic diseases are complex and long-lasting disorders which cause disability and death worldwide. To counter the increasing trend, studies show that advancements in digitizing parts of the healthcare could make the treatment of patien

The plan for the final disposal of spent fuel front Swedish nuclear power plants is to place it in copper canisters that are sealed and stored in a deep repository. The canisters will be sealed by friction stir welding (FSW) and the reliability of this process has now been evaluated. The reliability study was performed in three steps: first an optimization experiment to identify optimal process se

Abstract in UndeterminedThe dominant explanation for China's unprecendented rates of economic growth in the last three decades has regarded them as the consequence of the reform policies that, after Mao, the Chinese leaders embarked upon in 1978. The present study, in contrast, argues for continuity between the socialist period and the post-refrom era in China's economic course.Chinse socialism, i

In this work, the influence of substrate bias voltage on the microhardness, adhesive strength, friction coefficient, and wear rate of AIP Cr2O3 films deposited on AISI 304 stainless steel substrates was investigated systematically. In the meantime, the wear failure mechanism of AIP Cr2O3 films in dry sliding contact was also analyzed and discussed. The results showed that the mechanical properties

Arrhythmic mammals are active both during day and night if they are allowed. The arrhythmic horses are in possession of one of the largest terrestrial animal eyes and the purpose of this study is to reveal whether their eye is sensitive enough to see colours at night. During the day horses are known to have dichromatic colour vision. To disclose whether they can discriminate colours in dim light a

Symptoms of fecal incontinence and constipation are common in the general population. These can, however, be unreliably reported and are poorly discriminatory for underlying pathophysiology. Furthermore, both symptoms may coexist. In the elderly, fecal impaction always must be excluded. For patients with constipation, colon transit studies, anorectal manometry and defecography may help to identify

In recent decades, many marine populations have experienced major declines in abundance, but we still know little about where management interventions may help protect the highest levels of marine biodiversity. We used modeled spatial distribution data for nearly 12,500 species to quantify global patterns of species richness and two measures of endemism. By combining these data with spatial inform

In recent years, the 'river basin as a management unit' approach has been adopted as a solution to water management. The situation between Swaziland, Mozambique and South Africa regarding managing the water resources of the Incomati, Maputo, and Umbeluzi shared river basins is an interesting case that might need a different approach. These rivers flow downstream to the Maputo estuary where their w

Context: Magnetic resonance imaging (MRI) combined with magnetic resonance spectroscopy imaging (MRSI), dynamic contrast-enhanced MRI, and diffusion-weighted MRI emerged as promising tests in the diagnosis of prostate cancer, and they show encouraging results. Objective: This review emphasizes different functional MRI techniques in the diagnosis of prostate cancer and includes information about th

For decades, foreign aid has been a way to uphold political relationships, promote growth and development as well as a response during emergencies. Research on the relationship between foreign aid and economic growth has been done extensively. However, research on aspects beyond economic ones is far more limited. To extend the discussion regarding foreign aid, this thesis examines foreign aid and

Purpose: The purpose of this thesis is to examine, which of those variables suggested by past research – i.e. consumer attitude, store image, perceived price, packaging and perceived quality - have a significant influence on the customer’s purchase behaviour of organic private labels. Methodology: A quantitative study with a deductive approach and a cross-sectional design was chosen to obtain qua

The purpose of this study was to gain insight into social workers’ views on young people who commit crimes, focusing on juvenile delinquency risk factors and the social work that is done for young people who commit crimes. Semi-structured qualitative interviews were conducted with ten social workers who have experience working with young people who commit crimes. The interviews were analyzed using

Through previous research, several factors concerning the lack of knowledge among professionals regarding their work with transgender clients have been identified. A need for more counseling support for transgender clients has also been identified. The following study aims to respond to these shortcomings by studying professionals in Sweden who have experience working with clients who are explorin

Denna examensuppsats resulterar med att principen om gemensamt men differentierande ansvar tillämpas med bästa resultat på det globala ansvaret att städa upp det fria havet från plastföroreningen, och att principen bekräftar att det föreligger ett historiskt ansvar för redan genomförda föroreningar av havet med plast. Även om uppstädningen är ett globalt samarbete är det industriländerna som har t
