Integrated Assessment and Modelling (IAM) provides an interdisciplinary approach to support ex-ante decision-making by combining quantitative models representing different systems and scales into a framework for integrated assessment. Scenarios in IAM are developed in the interaction between scientists and stakeholders to explore possible pathways of future development. As IAM typically combines m
Stable isotopes of nitrogen (delta(15) N) and carbon (delta C-13) were measured for Atlantic salmon Salmo salar and their intestinal cestode, Eubothrium crassum, sharing the same diet. Atlantic salmon muscle tissues were enriched in N-15 and depleted in C-13 compared to their prey (sprat Sprattles sprattus sprattus) and their intestinal cestode. There was no significant difference in delta N-15 or
The objective of this study was to investigate the feasibility of the Aerodynamic Particle Sizer (APS) and the Electrical Low-Pressure Impactor (ELPI) to study mass weighted particle size distributions. Unimodal and bimodal liquid test aerosols were produced to a small chamber. Simultaneous measurements were performed with an APS 3320, an APS 3321, an ELPI and a Dekati Low-Pressure Impactor (DLPI)
There are considerable biomass resources in the European Union (EU) and mature conversion technologies to exploit the potentials of bioenergy. The challenge confronting the EU and member states is how to accelerate the implementation of bioenergy systems. This paper contributes to the identification, analysis, and discussion of barriers for bioenergy in the EU. Adopting an innovative methodology i
The term 'synergy' - from the Greek synergia - means 'working together'. The concept of multiple elements working together towards a common goal has been extensively used in neuroscience to develop theoretical frameworks, experimental approaches, and analytical techniques to understand neural control of movement, and for applications for neuro-rehabilitation. In the past decade, roboticists have s
Popular Abstract in Swedish Syftet är att dels studera olika ventilationssystems förmåga att tillföra och föra bort luftflöden. Den andra delen av syftet är att studera konstruktionskriterier och energi användning för ett variabelflödessystem baserat på konstanttryckshållning av det statiska trycket på grenkanalnivå och som endast tillför uteluft. Ventilationssystemens luftflöden studeras med hjälOne part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only. To inves
The increasing focus on lithium-ion batteries (LIBs) in the context of electrification of transport sector has raised concerns about their high costs, resource and energy demands, environmental impact, and social supply chain risks. To address these challenges and maximize the value of LIBs throughout their lifecycle, circular economy (CE) strategies, such as reusing and repurposing, are being exp
The upcoming implementation of the ReFuelEU Aviation Initiative presents both challenges and opportunities for the European aviation sector. Starting January 2025, the EU’s aviation fuel mix must include at least 2% Sustainable Aviation Fuel (SAF), leading to higher operating costs for airlines due to SAF’s higher price than fossil kerosene. Additionally, the entire fuel supply chain will need to
Fresh water resources face risks due to urbanisation, economic development, and climate change (CC). Many small and medium-sized cities (SMCs) are particularly vulnerable to these risks due to the lower resource capacity required to mitigate them. Nature-based Solutions (NbS) for water resource management (WRM) are promising to tackle these issues in urban areas while providing extra benefits to s
In this thesis, a fault detection and diagnosis system is developed for the Crazyflie 2.1 unmanned aerial vehicle. Different types of faults are investigated and suitable methods and tests are implemented. The system is mainly developed for the lighthouse positioning, but the tests and methods are generic and suitable for other parts of the Crazyflie eco-system. For the faults investigated, differ
In this thesis work, the design challenges of building a robust Battery Management System with the existing solutions are discussed highlighting the communication within the battery pack. The initial plan of this master thesis work was to investigate wireless BMS technologies and to implement a wireless BMS, as a demo prototype for three segments with wired BMS for a full 7.2 kWh battery pack. Aft
Purpose – The purpose of this master thesis is to examine the profile of contemporary skills and knowledge provided in Logistics and Supply Chain Management (LSCM) postgraduate programs offered by Swedish universities and compares them with job requirements. Design/methodology/approach – This master thesis employs the desk-based research involving content analysis based on 14 postgraduate LSCM pro
Spread options have become very popular in basically every sector of the financial markets, although the pricing of these derivatives still remains a challenge. In this thesis we examine the pricing of spread options using the fast Fourier transform (FFT). We implement a FFT method derived by Hurd and Zhou [10] and investigate the performance of the method under three different market models: the
Medier och sport är nära relaterade och påverkar varandra. Den utveckling som sker på mediefronten i Sverige idag, inom framförallt digital-TV borde då även påverka den allsvenska fotbollen. Om den då gör det, hur gör den det och vad kan det ge för konsekvenser? Syftet med uppsatsen är att ge en bild av hur förhållandet ser ut idag mellan TV och allsvensk fotboll samt vad som kan tänkas hända i fr
As there currently are not so many known studies which directly evaluate how diversity indices have been used in different contexts, following literature study was made with the purpose of investigating how three of the most commonly used diversity indices (including Shannon-Wiener’s and Simpson’s Indices as well as a certain index measuring taxonomic diversity) are representing different categori
The objective of this thesis is to investigate how public Swedish family firms managed to perform during the most recent recession that started in 2008. Accounting data is combined with information regarding ownership structure to examine family firms’ performance in comparison to non-family firms. Our evidence implies that family firms perform better in terms of operating performance (return on a
Background: Electroencephalography (EEG) is widely used to assess neurological prognosis in patients who are comatose after cardiac arrest, but its value is limited by varying definitions of pathological patterns and by inter-rater variability. The American Clinical Neurophysiology Society (ACNS) has recently proposed a standardized EEG-terminology for critical care to address these limitations. I
