Society faces multiple and interconnected crises that require transformation. Education has long been theorized as key to transformation, yet an important driver of transformation, imagination, is marginalised within pedagogical approaches to sustainability. This thesis examines Beyond the Fossil Era (BFE), a pedagogy that invites learners to become co-creators of a speculative museum looking back
With an increasing emphasis on sustainability, and the necessity to align with new regulations, companies face the challenge of transforming their business models to incorporate circularity. Many companies today operate according to a linear business model, where products are designed for consummation and disposal. However, to comply with new demands surrounding sustainability, companies will need
With the vigorous development of the electric vehicle industry, there is an increasing demand for high-capacity, high-stability batteries, and higher requirements are also placed on clean, non-toxic, and efficient battery production processes. The electrode is one of the most important components in lithium-ion batteries. It determines the capacity and overall performance of the battery. The fabri
The violation of baryon number, B, is a vital component of a process promoting the excess of matter over antimatter, as it is necessary to explain the baryon imbalance observed in the universe. Since experimental evidence for such an occurrence has yet to be discovered, the HIBEAM-NNBAR experiment, at the European Spallation Source facility, is a proposed two-stage program aimed at expanding the c
Machine learning has been growing in popularity for many years now and is currently popular among both businesses and private individuals. Running machine learning models takes a lot of computational resources, which means a large amount of energy is consumed. The aim of this thesis is to investigate the usage of machine learning model specific hardware on Field Programmable Gate Arrays (FPGAs) a
Chirality can be understood as a property of an object that cannot be superimposed on its mirror image, such as our left and right hands. It is ubiquitous in nature and can also be found in the photosynthesis process involving chlorosomes from green sulfur bacteria. Understanding the dynamics of chiral properties in chlorosomes, due to the excitons formed by the interaction between bacteriochlorop
Purpose – The purpose of this master’s thesis is to investigate the applicability and functions of tender platforms for logistics projects hosted by consultancy firms (CFs), and the benefits and challenges for logistics companies. Background – The digitization trend has transformed procurement practices, with e-tendering and tender platforms gaining attraction across industries. This shift is gra
Event generators are useful for simulating collision experiments in high-energy particle physics. In the event generator PYTHIA 8, parameters may be varied to compare competing models against experimental data. It is then beneficial to employ reweighting techniques to explore the results for multiple parameter values with only one simulation. This study aims to develop and implement a reweighting
In the automotive industry today, safety is of highest priority. ASIL is a safety standard that quantifies risk. This project investigates how a redundant speed estimate in a sensorless BLDC motor can be developed to meet ASIL B requirements. The proposed solution involves tracking the shape of the phase curve to determine the angular velocity. This is accomplished by changing the boundaries on th
I detta arbete diskuterar jag problematiken kring olika radiometriska dateringsmetoder samt möjligheten att generera noggranna och precisa dateringar. Goda dateringar av nedslagskratrar är en förutsättning för att undersöka intensiteten av nedslag på vår planet, korrelationen till massutdöende eller de hydrotermala system som uppstår efter ett nedslag och pågår i tusentals år. Problem relaterade tIn this study, I discuss the issues related to radiometric dating methods and the possibility of generating accurate and precise ages. Such dating of impact craters is crucial for investigating impact intensity, correlation with mass extinctions, or the hydrothermal systems that form after an impact and last for thousands of years. Problems related to both analytical and geological causes can resu
The chirality-flow formalism has been proven to simplify the calculation of helicity amplitudes, both analytically and in a first numerical implementation developed as an extension of MadGraph5_aMC@NLO. Expanding on this work, two new implementations have been developed. The first provides an alternative algorithm for the evaluation of diagrams, where helicity amplitudes are obtained by combining
The aim of this thesis project has been to develop an architecture for L2 ethernet switches that would be optimized for silicon area, targeting smaller low-end switches. A selection was made of three different switching architectures, which were compared and analyzed to explore the benefits and drawbacks of different approaches. From these, one architecture called Shared Memory Linked-List was sel
As time is moving forward, the world is becoming more dependent on Internet of Things (IoT) devices. The vision for the future involves IoT devices participating in various aspects of our daily lives, including sensing, controlling, and communicating. Such a future requires a significant number of IoT devices, which raises questions regarding sustainability in terms of battery waste. One promising
In this Bachelor thesis we will provide a light treatment to the topic of optimality gaps and regularity for integral functionals. First we will establish the classical existence result by Tonelli, via the so calleddirect method. Proceedingly we discuss examples of gaps between the infima over different classes of functions. We start with the classical Lavrentiev phenomenon (gap between AC and Lip
Surveillance cameras are used for video monitoring. To complement the video stream, different external accessories can be attached to a camera. The addition of external accessories brings certain limitations in terms of aesthetics and functionality. To overcome these limitations, an internal platform for connecting accessories would enable the creation of better and more future-proof products. Thi
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
Förevarande studie utforskar betydelsen av partisanship när svenskar exponeras för politisk desinformation genom fake news.
