Can constructed wetlands be used to fight cyanobacterial blooms? Cyanobacterial blooms are more than just a nuisance that prevents swimmers from making the most of the warmest months. Cyanobacterial blooms can cause a wide array of problems such as polluting freshwater reservoirs and causing fish die offs, owing to their ability to grow rapidly and release toxins which are harmful to both humans

A prerequisite for the effective conservation of species, is the accurate assessment of a species’ distribution and numbers. In order to look into the population sizes of birds, a quantitative atlas project from 1981 included a total count of the inland birds in the Faroe Islands. The aim for my thesis was to look at the population changes from 1981 until 2020, by repeating the 1981 atlas project,

There is a need for harmonisation of stability study designs of monoclonal antibodies. Monoclonal antibodies (mAbs) are widely used in treatments for various diseases. Like all drugs, their quality must be verified through stability studies. The ICH guidelines give general recommendations regarding stability studies of antibodies, and specifications should often be determined on a case-by-case bas

There is uncertainty about whether AI-generated output can and should be protected under EU copyright law and, in that case, who should obtain the rights. This thesis examines this legal issue by interpreting the legal text especially the InfoSoc Directive, case law and by considering legal scholarships. It has been established in the thesis that an AI-generated output can be considered protectabl

Modern vetenskap och teknik är starkt beroende av avancerade datorsimuleringar för att lösa komplexa problem, till exempel inom klimatmodellering eller flygteknik. Dessa simuleringar kan dock vara extremt beräkningskrävande, särskilt när man måste följa systemets utveckling över lång tid. I denna avhandling utvecklar vi en ny metod för att skapa förenklade modeller som behåller noggrannheten hos dReduced-order models (ROMs) have become indispensable tools for reducing the computational complexity of high-fidelity simulations in science and engineering. In this thesis, we introduce a novel training framework that combines the integral form of Operator Inference (OpInf ) with adjoint-state methods to yield robust, data-driven ROMs. By formulating a continuous-time loss functional that integr

With food shortage becoming a growing problem at the same time as the world population increases and cities become more densely populated than ever before, resource efficiency has become a more dire issue than ever. One major problem in food production today is that production efficiency is very weather dependent, transportation is also a big factor in environmental impact and almost half the worl

This project has been about understanding the public furniture market from a designers perspective and to develop a competitive design concept based on the needs of different stakeholders in the field of outdoor public products. The research has been mainly in forms of interviews and observations with a focus on Stockholm as geographical scope. I chose to focus on one city as the structure and r

När man pratar om industriellt underhållsarbete är mänskliga fel ett viktigt ämne att hantera. Olika typer av mänskliga misstag till följd av farliga tillstånd i vissa speciella parametrar, s.k. Performance Shaping Factors (PSFs) introducerar nya och oförutsägbara risker. Detta examensarbete presenterar en metod som, till skillnad från många metoder som finns tillhands idag, är tänkt som en enkel When discussing industrial maintenance, human error is a topic that easily comes to mind. Slips, lapses and mistakes due to hazardous settings of critical conditions referred to as Performing Shaping Factors (PSFs) introduce unforeseen and unanticipated risks. Unlike several tools to date, the methodology presented in this master thesis is thought to serve as an easy and fast way to identify risks

I en tid med återuppbyggnad av svenskt totalförsvar efterlyser olika aktörer ytterligare kunskap om civilsamhällets frivillighet. Den tidigare forskningen om frivillighet inom det här området saknar ett djupare individperspektiv kring hur frivillighet upplevs av den civila frivilliga, i förhållande till plikt, ansvar och krav. Syftet med denna fallstudie är därför att med kulturanalys fördjupa kunIn a time of reconstruction of the Swedish total defence various actors seek more knowledge about volunteering within the civil society. Previous research on volunteering in this area lack deeper micro perspectives on civil experiences of volunteering in relation to duty, responsibility and demands. Therefore, the purpose of this case study has been to deepen the cultural analytical knowledge of t

This thesis explores a video phenomenon called “Let’s Play”, that allows people to share their gaming experience with an online audience, for example on YouTube. Let’s Play-videos are a favorite pastime with children. Yet, the knowledge about the information in these videos is sparse. The aim of this study is to contribute with knowledge about how Swedish Let’s Play-producers on YouTube, targeting

En radar använder elektromagnetiska vågor för att kunna skicka och motta signaler. Precis på samma sätt som att våra öron, ögon och tungor är mottagare och vår röst och vårt kroppsspråk är sändare av signaler till världen omkring oss. För både människan och för radarn så behövs det skydd mot omgivningen. Till exempel, har våra ögon ögonlock och vår röst är dold inne i halsen. Utan ögonlock skulle The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. Radomes come in many different shapes, materials and thicknesses, where each of these parameters are decided based on the need for the given radar applicati

Att bedriva yrkesmässig verksamhet med uppfödning och träning av hästar som huvudsaklig syssla har blivit vanligt förekommande. Liksom för all yrkesmässig verksamhet, behöver ett företag som arbetar med hästar nå upp till en viss ekonomisk nivå för att anses vara näringsdrivande och inte klassas som hobbyverksamhet. Dessa krav kan vara svåruppnåeliga för en hästföretagare, vilket ofta beror på attIn Sweden the Consumer Sales Act (Konsumentköplagen 1990:932) is applied on sales of movables, when the seller is a businessman and the buyer is a consumer. The law was modified in 2002 after an EU-initiated directive - Directive on the Sales of Consumer Goods and Associated Guarantees (1999/44/EC). The directive applies to all member states in the EU and sets out the minimum level of consumer pro

To study and compare the safety of intersection, traffic scientists today typically manually monitor the intersection during several days and count how often certain events such as evasive manoeuvres occur. This is a laboursome and costly procedure. The aim of this thesis is to provide tools that can reduce the amount of manual labour required by using automated video analytics. Two methods for cr

Background: Performance of migrating birds can be affected by a number of intrinsic and extrinsic factors like morphology, meteorological conditions and migration strategies. We compared travel speeds of four raptor species during their crossing of the Sahara desert. Focusing the analyses on this region allows us to compare different species under equivalent conditions in order to disentangle whic

Gravitational encounters between a single star and a binary system can frequently occur in the cores of dense stellar systems like globular clusters. These three-body scattering encounters can lead to a variety of outcomes since the energy of the binary components can be exchanged with the interacting single star. The outcome of these interactions strongly depend on the initial conditions of the i

The cost of developing and researching novel molecular compounds in the pharmaceutical industry is very high today. If an actor accidentally releases too much information about a novel molecule to the public the molecule becomes prior art, and as an effect, can not be patented. This has resulted in a fragmented space where collaboration across organizations is virtually non-existent. We propose a

The thesis aims to understand if seed saving practiced by oppressed small-scale farmers and peasants who are affiliated with Navdanya can be seen as a technology of resistance against the dominant agri-food industrial paradigm. Another aim is to find out how political and cultural meanings are attached to seed saving. It also aims to challenge this aforementioned paradigm. The inquiry is exemplifi
