Biases in animal behaviour research are inevitable consequences of our societal and cultural standpoint. To remove our biases, the first stage is to identify them. We call on individual researchers to adopt a more active approach to addressing bias within their research. We propose that biases exist within a matrix defined by the general acceptance of a bias's existence and the understanding of th
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
A Credit Default Swap spread is a reliable measure of credit risk as it is the compensation demanded by a party to bear this risk. Officially, credit risk is denoted as credit ratings announced by credit rating agencies. Since rating announcements contain information regarding credit risk, the market should incorporate this new information into the CDS spread. The aim of this study is to investiga
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
This master thesis investigates the synthesis, structural characterization and electrochemical performance of copper(II) oxide (CuO) and cobalt-doped CuO nanofibers as electrocatalysts for the electrochemical nitrate reduction reaction (NO3-RR). The overarching aim is to assess their potential for sustainable ammonia production under ambient conditions. A series of exploratory synthesis trials rev
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
Future climate scenarios are predicting considerable threats to sustainable maize production in arid and semi-arid regions. These adverse impacts can be minimized by adopting modern agricultural tools to assess and develop successful adaptation practices. A multi-model approach (climate and crop) was used to assess the impacts and uncertainties of climate change on maize crop. An extensive field s
Galectins are a family of carbohydrate-recognising proteins involved in regulation of cell adhesion and cell signaling, leading to roles in e.g. cancer progression, fibrosis, and ulcerative colitis. Glycomimetic galectin inhibitors based on different molecular scaffolds are known and have demonstrated effects from cell experiments to the clinic. Presented here is the synthesis and evaluation of 3-
Certain oxygenated compounds, called oxygenates, when blended with gasoline, have the ability to inhibit the occurrence of engine knock, thus helping improve spark-ignition engine efficiency. Similarly, oxygenates can also be added to diesel fuel to decrease the exhaust emissions—soot in particular—from diesel engines. Although ethanol and biodiesel have had widespread use as oxygenates for gasoli
In the 20th century, the scientific community recognized global climate change as a preeminent challenge facing our planet. The primary driver of this predicament was identified as the substantial reliance on fossil fuels, constituting approximately 80% of the world's energy consumption. The combustion of these fossil fuels, particularly those rich in carbon, led to the emission of greenhouse gase
