Bioacoustic sound event detection (SED) is a critical field for biodiversity monitoring, yet the high cost of annotating data poses significant challenges. This thesis explores the application of active learning strategies to reduce the amount of annotated data required for effective model training. This is done for a segment based SED model, where batch active learning is performed by querying fu
The need for speed in communications systems is increasingly prevalent in modern society, which is one of the driving factors for the evolution of new technologies. At the forefront of this evolution are Multiple-input Multiple-output (MIMO) systems. Through the usage of many antennas at the base station (BS) and user equipment (UE), significantly enhances the potential maximum data transfer rates
Flooding in oil palm plantations in Southeast Asia is a common problem. The oil palm’s habitable range is restricted to lowland equatorial areas, and the high rainfall and degraded landscapes associated with oil palm cultivation leaves oil palm prone to flooding. Flooding diminishes yields in mature palms, increases mortality in young palms, and disrupts operational processes. This reduces the ec
In October 2022, the European Commission announced a legislative proposal to make instant payments in euro available to all citizens with a bank account in the EU and EEA countries. When adopting new payment technologies, it can be challenging to balance security and convenience. Consideration must be given to whether compromised security is an unavoidable effect of instant payments or if both obj
This study investigates interculturality in health communication and deriving power relations. The Bilharzia Storytelling Lab 2022 in Kigali is a health communication program devoting significant attention to the role of culture and representing a new approach to respectful health communication practices. Exploring the Storytelling Lab methodology and its roles provides insights into the innovativ
Credit activity is essential for financial institutions, acting as the primary means banks deploy resources and generate revenue. As a key indicator of financial distress, corporate default has severe repercussions on investors, creditors, regulators, and policymakers. Credit risk embodies the uncertainty banks confront prior to lending, accounting for the partial or complete non-recovery of loan
The current reality is that cities are losing green spaces rather than creating more of them, leading to many urban challenges. Urban nature-based solutions (NbS), through renaturing urban landscapes, are seen as a promising solution to help cities deal with climate change and build a better future for communities worldwide. In Europe, specifically, NbS is also seen as a way of boosting green innov
The maturation of whisky is a long and complex process, the extremely long waiting time causes a large cost for new whisky distilleries, and without sufficient funding, it is hard to start a whisky business. To produce satisfying whisky products within the short term, accelerating the reaction during aging provides a promising approach. Various chemical reactions take place during this stage, this
The unicellular green alga of genus Chlamydomonas are well studied within the fields of photosynthesis and flagellar research. Although many molecular tools have been developed for use on Chlamydomonas, little research has been done on its ecology and population dynamics. Species within the genus are morphologically indistinguishable using light microscopy and as such a molecular method is necessa
I denna avhandling har jag kritiserat EPI (Environmental Performance Index) och det sätt ett lands hållbarhetspolicy tenderar att mätas. Jag har granskat tidigare bortsedda aspekter av nationernas miljöpolicy och försökt föra dem fram i hopp om att dessa kommer att användas för framtida miljömätningar. Jag har också tittat på sambandet mellan jämställdhet och statlig miljö och försökt hitta empiri
Based on the context of a developing country, this research engages key identified political-economy aspects that influence the operations and performance of the electricity supply industry in Tanzania. Departing from this political-economy perspective, this paper explores dencentralized approaches to rural electrification through agro-industry co-generation and influencing factors behind the slow
There is a global demand for sustainable industrial development and a call to make manufacturing “greener”. Nanotechnologies are in a promising position to be early adopters of this concept. Advancements in the nanomaterial industry can help confront global issues, and aid in sustainable development that enables positive economic, environmental, and social changes. Formal evaluation of a product’s
This is a representation study of the antagonist character and monstrous female vampire Drusilla from the TV-show ”Buffy the Vampire Slayer” (1997). The purpose of this study is to find out how Drusilla as an antagonist is portrayed from a feministic perspective. The theories that are used focus on monstrous female, sex, motherhood and female objectification in TV, film and literature. Using these
Female drivers operating in the public transport sector are underrepresented in the literature on women’s mobility which largely addresses the fear of crime among female riders. Alternative modes of transport, as well as job opportunities, have nevertheless started to emerge as international and local ride-hailing firms mushroom across the globe in urban cities. The World Bank Group International
The global transport industry stands in front of the next big technology shift; the implementation of autonomous vehicles. This shift might remove the physical driver from the truck, increase safety and improve flexibility. This will most likely change the fundamentals of the transportation industry. Autonomous trucks are anticipated to be implemented for short distance transportation in gated are
Efforts to reform the public sectors of Zambia have been ongoing since the 1990s with objectives to ensure efficient and high-quality provision of public goods and services to all citizens and battling persistently high levels of poverty. Outcomes have however been mixed at best. This study assesses how reforms to the public sectors of Zambia have been framed in terms of what problem representati
Wetland and biodiversity loss affect both ecosystem function and human wellbeing. However, it is argued that the incremental rate of farmland abandonment provides opportunities for ecological restoration to help reverse this negative trend. This thesis applies ecosystem service framework and psychological ownership theory to analyse a wetland restoration project in a semi-urban town of Jablonné v
A translocation between chromosomes 9 and 22 produces the fusion gene BCR-ABL that leads to the constitutive activity of a tyrosine kinase. This initiates the uncontrolled proliferation of myeloid cells causing Chronic Myeloid Leukaemia (CML). The disorder is treated by tyrosine kinase inhibitors (TKIs) that prevent the progression of CML into more advanced phases. The treatment must be sustained
