Popular Abstract in English This thesis is concerned with the efficient generation of ultra-short light pulses, far beyond the visible spectral range. Such light pulses can reach durations below 100 attoseconds, where one attosecond is one billionth of a billionth of a second. Why do we want to generate such extreme light pulses? Our knowledge of basic processes in physics and chemistry is to a High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. However, the rather low efficiency of the HHG process, which implies a limited pulse energy and repet

The comfortable garment is about creating a comfortable experience with all that it implies, both physiologically and psychologically. The project describes the interaction between expectations and needs, in and across situations, in order to be and feel prepared, relaxed, and while still well dressed. The Expectation of this project is that it should be an eye opener to take get new knowledge abo

The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. The use of biomass gasification for energy purposes can help lower the net emissions of greenhouse gases,

We study a scenario where a monitor is interested in the freshest possible update from a remote sensor. The monitor also seeks to minimize the number of updates that exceed a certain freshness threshold, beyond which, the information is deemed to be too old. Previous work has presented results for First Come First Served (FCFS) systems. However, it has been shown that Last Come First Served (LCFS)

This essay is an overview about research in EE, Expressed Emotion, during the years of 1972 – 2008. This concept comes from research on schizophrenia where it became apparent that in families having high EE, as exemplified by hostility, criticism and overinvolvment, the patient had a larger risk of recurrence. To evaluate EE most often the Camberwell Family Interview is used. The concept of EE has

Nowadays the technology is progressing continuously. The designers are developing products with new features and always giving to the user an innovative technological solution for the society problems. The standard methods to design new devices are becoming slower for the demand of the products. Due to this growing complexity, some possible substitutes of the traditional Register Transfer Level (R

Popular Abstract in English Sugar is the main source of energy in our bodies. If your blood sugar drops below a certain level, it can cause serious damage to your brain. On the other hand, having a very high blood sugar level for a long time can cause diabetes. For this reason, blood sugar levels in our bodies are maintained within a certain range by a group of hormones that work together. These hIslet dysfunction is central to the development and progression of type 2 diabetes (T2D). Epigenetic modifications are essential for establishing and maintaining cell identity and function in normal circumstances. Exposure to adverse environmental factors may alter the epigenome, and result in changes of gene expression and the resulting phenotype. The aim of this thesis was to analyze DNA methyla

There are high demands on companies today to survive when competition is high and that also applies to companies that manufacture ethylene oxide. The raw material in the production of ethylene oxide is ethylene and oxygen where ethylene is the largest cost. To facilitate the reaction a catalyst, which increases the reaction rate, is used. The catalyst has a major influence on the efficiency and ec

This study is an assessment of the functioning of the three year old Transparency Mechanism. The mechanism has a surveiling role in the WTO of the Regional Trade Agreements (RTA). Formation of RTAs has been increasing rapidly during the latest twenty years, causing a tension in the multilateral trading system. RTAs give more preferable treatment to parties within the agreement than to trading part

A series of homoleptic bis(tridentate) [Ru-(L)(2)](2+) (1, 3) and heteroleptic [Ru(L)(dqp)](2+) complexes (2, 4) [L = dqxp (1, 2) or dNinp (3, 4); dqxp = 2,6-di(quinoxalin-5-yl)pyridine, dNinp = 2,6-di(N-7-azaindol-1-yl)pyridine, dqp = 2,6-di(quinolin-8-yl)pyridine) was prepared and in the case of 2 and 4 structurally characterized. The presence of dqxp and dNinp in 1-4 result in anodically shifte

Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. Some plants can recognize these effectors via resistance proteins that reactivate plant defence and lead to effector

Popular Abstract in English Nowadays, the majority of energy production comes from combustion which is universally linked to daily human activities. Public awakening of the environmental effects of combustion pollution evokes extensive research activities in improving combustion efficiency and reducing pollutant production. Development of combustion processes also includes the use of renewable bioThe work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons

3D pose estimation is a crucial element for enabling robots to work in industrial environment to perform tasks like bin-picking or depalletizing. Even though there exist various pose estimation algorithms, they usually deal with common daily objects applied in lab environments. However, coping with real-world industrial objects is a much harder challenge for most pose estimation techniques due to 3D pose estimation is a crucial element for enabling robots to work in industrial environment to perform tasks like bin-picking or depalletizing.

Due to the refugee crisis that evolved in 2015, the Swedish Government introduced a new refugee policy in order to decrease the number of asylum seekers arriving in Sweden. This new refugee policy resulted, among other things, in a temporary law that limits the possibilities to receive a residence permit in Sweden. The temporary law has received a great amount of criticism from several consultatio
