Turning the tide on marine biodiversity loss: How Swedish coastal cities are leveraging citizen interaction to improve conservation outcomes

Rapid coastal urbanization and declining marine biodiversity rates are complex problems that require broad, integrated sets of solutions. Although isolating nature from human impact prevails as the standard conservation approach, social-ecological systems require more holistic solutions. Coastal cities have the opportunity to encourage human interaction with nature – while still achieving positive

Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. The model is a stoichiometric pre-sorted polyethylene feed and is based on experimental pyrolysis results. Product

Machine Condition Monitoring of Production Equipment

This study investigates the possibility of implementing a machine monitoring system on IBAS2, a production machine responsible for aligning an optical lens with an image sensor. A machine-monitoring system could possibly reduce downtime, costs, and production recalls. After examining IBAS2, vibration analysis emerged as a promising monitoring approach. The research aimed to capture the natural vib

Kunskapssammanställning över kravställning på cykelbanor inom kommuner

Cykeln är en avgörandefaktor för en uppnå en samhällseffektiv och långsiktigt hållbar transportförsörjning där en mer attraktiv cykelinfrastruktur kan ge upphov till att fler väljer att resa med cykel i stället för bil. Överflyttningseffekterna från biltrafiken skulle innebära en reduktion av avgasutsläpp, icke-avgaspartiklar från vägtrafik, bulleremissioner och mindre trängsel i staden. SamtidigtBicycles are a prerequisite for a long term sustainable transportation service, where a more attractive infrastructure would contribute to a more sustainable transport mode such as cycling in favour of using motor vehicles. Success in changing the main mode of travel from cars to bicycles would result in reduction of greenhouse gas and exhaust emissions, non-exhaust emissions, noise pollution and

Widows, land rights and women’s empowerment: “Who will own the kitchen”? - findings from the Kilimanjaro region, Tanzania

Women around the world are constantly being denied their land rights due to discriminatory practices. Widowed women are particularly at risk. This prevents advancing women’s empowerment and women’s equal opportunities for participation and leadership at all levels of decision making processes. Through a qualitative case study within the Chagga community in Kilimanjaro, Tanzania, this thesis’ aim i

Optimizing First-Order Method Parameters via Differentiation of the Performance Estimation Problem

This thesis treats the problem of finding optimal parameters for first-order optimization methods. In part, we use the Performance Estimation Problem (PEP), a framework for convergence analysis of first-order optimization methods. The fundamental idea of the PEP is to formulate the problem of finding the worst-case convergence rate of a first-order optimization algorithm, as an optimization proble

Avoiding Misattribution Errors through Recollection: Can Retrieval Practice Suppress the Illusory Truth Effect?

Misinformation is a major global issue and presents major negative impacts on many aspects of our lives. One of the factors facilitating misinformation belief is the illusory truth effect, the phenomenon of how repeated exposure to information can increase subjective truth. This occurs when processing fluency, caused by repeated exposure to an item, is misattributed to the truth status of an item.

A glimpse from inside the "EU bubble": A qualitative interview study of European youth doing traineeships at the EU institutions

European citizens demand more bottom-up debates in opposition to the existing elite-driven voices heard within European policymaking. The youth is one of the groups which demands more participation and involvement, and the EU is partly involving young people by having trainees at the EU institutions. With the goal of hearing the voice of these young people and getting insights on youths’ experienc

Överturism - Existerar det på Gotland? - En kvalitativ studie baserad på aktörers och lokalbefolkningens attityder

Problemdiskussion: Turism är en växande sektor som idag är viktig för flera destinationer. Kombinerat med att den tekniska och digitala utvecklingen, som skapat lättillgängliga och billigare resor vilket har resulterat i en högre efterfrågan, bidrar detta till ett intressant balansproblem där överturism har blivit allt mer diskuterat. Detta fenomenet är väl förekommande på flera europeiska destina

Macro-based Adjustment Factors for Valuations in Venture Capital

This paper focuses on creating macro-based adjustment factors which can be applied to the valuation of start-up companies. Since start-up companies are private, market valuations are limited to events such as funding rounds or M&A transactions, which happen only at discrete points in time. This is a drawback when compared to the continuous valuations produced in public markets, with current li

Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. In this study the porosi
