Antennas are one of the key components that empower a new generation of wireless technologies, such as 5G and new radar systems. It has been shown that antenna design strategies based on modal theories represent a powerful systematic approach to design practical antenna systems with high performance. In this thesis, several innovative multi-antenna systems are proposed for wireless applications in
Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. This leads to major uncertainties in Holocene solar reconstructions. This PhD project aims to improve the Holoc
BackgroundIn primary health care people with mental health needs are often overlooked or masked with physical complaints. It has been suggested that public health nurses lack sufficient knowledge when encountering people with mental health problems. Low levels of mental health literacy among professionals are associated with negative patient outcome. There is a need to understand public health nur
BACKGROUND: Many factors influence housing choices among older adults, but far from all have been identified. There is little systematic analysis that has included economic factors and virtually no knowledge about the interplay among perceived costs of moving, health status, and the mobility rate of older homeowners. It is currently unclear whether economic factors influence older adults' willingn
The steel and chemical production industries are the largest industrial emitters of greenhouse gases in the European Union, together accounting for half of the EU’s industrial greenhouse gas (GHG) emissions. A promising strategy for achieving deep GHG emissions reductions is the electrification of these two industries, which would depend on the rapid expansion of renewable electricity supply. Such
In the numerical integration of nonlinear autonomous initial value problems, the computational process depends on the step size scaled vector field hf as a distinct entity. This paper considers a parameterized transformation hf↦hf∘(I-γhf)-1,and its role in the finite step size stability of singly diagonally implicit Runge—Kutta (SDIRK) methods. For a suitably chosen γ> 0 , the transformed map is L
BACKGROUND: There has been a growing body of evidence associating consumption of ultra-processed foods (UPF) with adverse health outcomes including depression, cardiovascular disease, all-cause mortality. However, whether UPF are associated with dementia is unknown. The authors investigated the associations between UPF and dementia incidence in UK biobank.METHODS: We included 72,083 participants (
Meteorological investigations were carried out in forests in the southwestern part of the Swabian Alb (SW Germany) to analyze the influences of exposition and silvicultural treatment on the microchmate within various stands of beech (Fagus sylvatica L.). The measurements were taken as part of an interdisciplinary project on the effects of climate and forest management on structures and processes w
In boreal summer, circumglobal Rossby waves can promote stagnating weather systems that favor extreme events like heat waves or droughts. Recent work showed that amplified Rossby wavenumber 5 and 7 show phase-locking behavior which can trigger simultaneous warm anomalies in different breadbasket regions in the Northern Hemisphere. These types of wave patterns thus pose a potential threat to human
On a planetary scale, the D/H ratio on Mars is a key diagnostic for understanding the past history of water on the planet; locally, it can help to constrain the sources and sinks of water vapor through the monitoring of condensation and sublimation processes. To obtain simultaneous measurements of H2O and HDO lines, we have used the Echelle Cross Echelle Spectrograph (EXES) instrument aboard the S
The sparse iterative covariance-based estimation (SPICE) algorithm is promising for hyperparameter-free sparse source location for time-division-multiplexing multiple-input-multiple-output (TDM-MIMO) radar systems, with well-documented merits in resolution enhancement and sidelobe suppression. Regrettably, the method typically requires a large number of iterations to converge, each requiring high-
Objective: We investigated differences in somatosensory profiles (SSPs) assessed by quantitative sensory testing in children and adolescents with cerebral palsy (CCP) with and without chronic pain and compared these differences to those in a group of typically developed children and adolescents (TDC) with and without chronic pain. Method: All included subjects were consecutively recruited from and
Popular Abstract in English These days we hear a lot about sustainability and most of us try to live in a more sustainable way. We use less water and energy, we sort our household waste and we prefer to consume products that are produced with less negative human impact. However, when it comes to our own excreta we definitely think of it as waste. And we are glad enough that wastewater treatment syEutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. To date the main global effort has been to remove such nutrients at source. However, with an increase in awareness of the
Lighting For Sustainable Development Lighting For Sustainable Development The Advanced Study Group of Lighting Appropriate lighting is a basic prerequisite for the quality of modern life. The electric light has enabled a great expansion of human activity. However, inappropriate light and light pollution also have serious side-effects on human health and quality of life. Furthermore, the energy and

Analysis and Design of an Adhesive Joint in Wind Turbine Blades Author: Jonatan Pettersson Creating a wind turbine blade which can be produced in sections and then assembled at the construction site is essential to further increase the length of blades and thereby also the power produc- tion. The dissertation shows that a very strong joint could be achieved, if designed properly, by using adhesive
