In this thesis, a study is made into relative positioning and control systems for flying wing Micro Aerial Vehicles (MAVs) intended to be used by the Swedish Sea Rescue Society (SSRS) for the purpose of providing assistance during sea rescue missions. The particular scenario of interest is robust relative positioning to be used for autonomous landing of a MAV on a boat at the end of a rescue missi

Reducing emissions in the basic materials sector, which account for 25% of the global greenhouse gas emissions is a pressing climate mitigation task. Investments into decarbonising this sector are critical and therefore raising capital though climate finance is gaining attention. Green bonds are a new asset class that incorporate sustainability criteria into bonds. Despite the increasing use of gr

Dissolved organic carbon (DOC) enters inland waters from the surrounding terrestrial ecosystems, and is assimilated by bacterioplankton, mineralizing it to carbon dioxide (CO2). This bacterial respiration (BR) is an important part of carbon processing in freshwater, but it is also a process of global significance; in oceans and inland waters combined, BR is probably the largest single sink of orga

Purpose: The purpose of this thesis is to understand how Corporate Social Responsibility (CSR) as knowledge is anchored in an organization. The importance of this anchoring comes from the organizational need to adapt to the contextual global awareness related to CSR, amplified by the organizational transparency and exposure. Methodology: A hermeneutical approach has been taken in this thesis. We h

Background The objective of this study was to provide a multimodal biomarker characterization of amnestic objective subtle cognitive decline (obj-SCD) in aging and preclinical Alzheimer’s disease (AD). Methods Prospective observational study; data from the Alzheimer’s and Families+ (ALFAs+) cohort, including cognitively unimpaired (CU) individuals with available baseline CSF biomarkers (normal or

Advanced Parkinson’s disease (APD) often presents challenges such as irregular gastric absorption and delayed gastric emptying, leading to significant and unpredictable fluctuations in both motor and non-motor symptoms. Our study is a real-world, open-label study of the tolerability and efficacy of subcutaneous infusion of Foslevodopa/Foscarbidopa (FL/FC) focus on comparing White Caucasian patient

Consumption of clothing, fashion and shopping has increased and the fashion industry is driven by the constant need for bigger profits while fashion consumption today is a major villain in the globalization debate. New shopping centers and malls are steadily built throughout Sweden, and the craving never seems appeased. But what is it that drives us to continually consume this excess amount of clo

There are a lot of debates surrounding the sustainability of liquid biofuel as a means of mitigating some global challenges like climate change and energy insecurity. The European Union (EU) for example has set up renewable energy targets and sustainability criteria. Biofuel is expected to contribute significantly to meet up with these targets. Much of these targets will be met by importing liquid

In this paper a combustion diagnostic method is presented where measured pressure data is used to calculate the heat release, local temperatures and concentrations of NO and other species. This is done by a multizone model where the lambda value, i.e. 1/equivalence ratio, in each zone can be chosen arbitrarily. In homogenous charge engines lambda is given by the global air/fuel ratio. The local la

Introduction Epidemiological observations suggest that sunlight exposure is an important determinant of hip fracture risk. The aim of this ecological study was to examine the relationship between latitude and hip fracture probability. Methods Hip fracture incidence and mortality were obtained from literature searches and 10-year hip fracture probability computed from fracture and death hazards. Re

Reducing emissions from forest degradation and deforestation, conserving and enhancing forest carbon stocks, and sustainably managing forests (REDD+) has emerged as one of the most anticipated climate change mitigation tools. This paper aims to understand and identify the underlying discourses that have dominated the emergence of REDD+, by identifying the key story lines in the policy and academic

Global positioning system and time-depth recorders were deployed in combination to investigate the foraging behaviour of common murres Uria aalge breeding at Stora Karlsö Island, Baltic Sea, during the chick-rearing period. In the pre-breeding period the main prey species of murres, sprat Sprattus sprattus, is targeted by commercial fisheries, likely reducing prey availability during the breeding

In order to get to know the loads on bone and other tissues there is a need to measure motion. So far, the best way of measuring human locomotion is done in a gait laboratory. But since the equipment is quite expensive and it isn’t mobile, it cannot be used for measuring on people during their daily activities. There is a great interest of finding easier ways to capture the motion in daily situat

Predicted flight trajectories differ depending on which orientation cues are used by migrating birds. Results from radar and satellite tracking of migrating birds can be used to test which of the predicted trajectories shows the best fit with observed flight routes, supporting the use of the associated orientation mechanism. Radar studies of bird migration at the Northeast Passage and the Northwes

The purpose of the thesis is to analyze the recent growth figures of China and understand whether China will be able to sustain its outstanding economic growth pattern, in a time when it needs to rebalance its economy from investments towards domestic consumption. In fact, if China does not rebalance its economy to a consumption-­led economy, it might face difficulties to repay the massive investm

Purpose: The thesis aims to create an understanding to set the foundation of the social media landscape covering its historical evolution, driving mechanisms and business models. Methodology: The thesis has a qualitative character and an explorative art of discovering the social media landscape. A theoretical framing of the thesis is inspired by Christensen and Raynor. Theoretical perspective: The

With a worldwide increase in climate-related disasters and the global temperature on the rise, the effects of climate change are already being felt. Among those most at risk are the poor in developing countries, often living in informal settlements or „slums‟. In order to reduce associated risks and strengthen people‟s own coping capacities, there is an urgent need for knowledge about the factors
