Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. More specifically, the use of new measures to optimize the weights of a weighted sum of spectrograms was tested and evaluated. The o

As the greenhouse gas emissions keep on increasing the need for solutions to help reduce emissions across all sectors has never been greater. The European Union has pointed out green hydrogen as a step in increasing the sustainability of the energy sector in Europe. Goals has been set to boost the development of hydrogen technology since the green hydrogen production today is only existing in an i

The adoption of the Rome Statute of the International Criminal Court identified for the first time in international criminal law the crime against humanity of persecution on gender grounds. The inclusion was however not uncontested, and especially the term gender was a source of debate during the negotiation process. Because of diverging national positions on what the term gender meant, it was dec

Social, ecological, and cultural impacts associated with the U.S. military in Hawaii are egregious. However, due to the historical oppressions and injustices to Hawaiians, the U.S. military maintains their hegemony by wielding a disproportionate decisive political and economic power. This study aims to explore perceptions of Native Hawaiian and non-native activists regarding the military impacts a

Oats (Avena sativa) are a cereal crop rich in dietary fibre, vitamins, antioxidants, and other nutrients. It is considered to have higher nutritional values compared to other cereals, with a higher fat content (2-13%). Oats also have high content of lipase enzymes when compared to other crops. The high lipase activity is unwanted in oats as it may induce hydrolytic rancidity, with a soapy, bitter

As Sweden has been a pioneer when it comes to agendas for the inclusion of women, the decision to terminate the feminist foreign policy was met with surprise. The newly elected government was quick at declaring the feminist foreign policy insufficient to represent Swedish interests and this research has provided insights to understand how this came to be. By analyzing the case with the application

Throughout the years, the church has played an integral role in the community. It has served as a spiritual hub, a political symbol, and a center point for the community. One thing that cannot be denied is that the church has had some sort of power and influence on the community throughout different periods of time. You may even argue if the impact it has had on the community is positive or not. S

Bakgrund: I Sverige råder det en obalans mellan behov och tillgång på organ och vävnad från avlidna. IVA-sjuksköterskor har en aktiv roll i donationsprocessen, en roll som forskning har visat kan upplevas som påfrestande. Syfte: Studiens syfte var att belysa sjuksköterskors erfarenheter av donationsprocessen på en intensivvårdsavdelning. Metod: En systematisk litteratursammanställning enligt Bet

Although based on decentralized principles, the World Wide Web has become highly centralized with a few multinational tech corporations hosting and providing all of the services most people use the internet for. This has led to the unproportionate power some companies hold over the world’s people and has wide consequences, not least is reduced integrity. As a response to this development, decentra

De allra flesta företags marknadsföring har blivit alltmer digitaliserad. Med hjälp av modern digital marknadsföring kan även företag med begränsade resurser effektivt nå ut till sin målgrupp, tack vare lättillgängliga verktyg och plattformar. Men de senaste åren har de ökade kraven på digital integritet inneburit gränsdragningar gällande hur datan som driver dessa verktyg får samlas in och hanter

Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. This thesis covers the development of a low-dimensional model for a l

Microplastics are a present and future threat to the sustainability of coastal socio-economic systems. Current solutions and management could be improved by developing citizen science programs to foster community engagement and knowledge generation. However, research is limited on the actual learning outcomes and impacts of citizen science. To help close this gap, this research builds upon existin

Addressing climate change will entail groups of people working together to bring about changes in fundamental societal structures. This research investigates how the members of three collective initiatives on climate change in Sweden envision the process of change, based on their understandings of structures and agency. Margaret Archer and Pierre Bourdieu’s theorisations on this matter serve as an

The aim of my thesis is to provide research-based insight into AI technologies for information seeking’s place in future school library operations. To achieve this aim, I am looking at Swedish school librarians’ perceptions and views on AI technologies for information seeking, especially in connection with their work on media and information literacy. My research questions are as follows: (Q1) How

The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. Rhinocort® is a nasal spray suspension manufactured by McNeil AB to reduce the severity of symptoms, and like all medicines, must und

The objective of this thesis is to examine Swedish climate law to discuss and examine the concept of “rights of future generations”. Global warming is inevitable causing the world to change rapidly, thus future generations will be faced with monumental environmental challenges. Recently, states around the world are being sued by the younger generations claiming their rights have been violated. As

Bakgrund: Oavsiktlig awareness innebär en misslyckad anestesi, det vill säga, patienten är medveten om sin omgivning, när den skall vara smärtfri, sövd och muskelrelaxerad. Oavsiktlig awareness drabbar 1:1000 till 1:20 000, det är oklart hur många som drabbas, då mörkertalet kan vara stort. Patienter har framfört oro inför oavsiktlig awareness. Anestesisjuksköterskan har ansvar att kontrollera ane

Studies on how small states act within the international system are usually performed using the major theories in international relations. After Russia’s invasion of Ukraine in 2022, Sweden applied for a membership in the North Atlantic Treaty Organization (Nato). This thesis’s purpose is to gain knowledge on how strategic narratives were used to legitimize policy changes in a nation that has been

This case study investigates the involvement of private military companies (PMCs) in two African conflicts. Nigeria and Mozambique hired PMCs in 2014 and 2019 respectively to combat internal insurgencies. The paper aims to answer why these countries hired PMCs and if the PMCs were successful in combating the insurgencies. For the first question, the intensity of the insurgency and the state of the
