A fleet of autonomous sailboat could change our perception of the planet. An autonomous sailboat could not only conduct environmental research but also perform month long operations through the energy efficient wind propulsion. This thesis is the work behind the development of an autonomous catamaran model sailboat. A new mathematical model is brought forward and implemented for simulations perfo
This report details the development and evaluation of fibre-based primary packaging concepts for the growing ready-meals category, focusing on a concept packaging design project for Micvac AB. The research methodology employed the Double Diamond of Design Thinking as an innovation model. The project encompassed an assessment of the desirability, feasibility, and viability of fiber-based packaging.
With the rapid growth of AI and large language models, concerns about their energy consumption have become increasingly prominent. The traditional digital von Neumann architecture is ill-suited for deep neural networks, prompting the exploration of neuromorphic computational models. These models draw inspiration from nature and the brain to integrate memory and computation efficiently. This thesis
Thesis purpose: To investigate the role of algorithmic literacy in the case of TikTok, and how its strategic performance, including the challenges and associated ethical issues, affects global marketers. Methodology: Adapting a social constructivist approach, twelve qualitative semi-structured interviews with global marketers allowed us to gather deeper insights Theoretical perspective: In order
This is a study of the promotion of democracy and governance as a part of Japan’s official development cooperation. Despite being one of few Asian democracies among aid donors, Japan’s work with democracy and governance has largely been overlooked in the discussion of its aid programme. This research seeks to expand on the current literature by examining what factors and driving forces interact to
Every day more devices all over the world are connected to networks. Some of these devices have microphones that could potentially be used in a networked array. This opens up the possibility to determine where sounds in the environment are produced, given the positions of the microphones are known. This thesis investigates the feasibility of using a number of network connected speakers with built-
This thesis examines what barriers and opportunities exist for public participation in addressing biodiversity loss and adapting to climate change in Swedish biosphere reserves (BRs). This was approached by conducting an instrumental case study of all seven BRs in Sweden, consisting of semi-structured interviews and a case-specific literature review. The results identified that while a significant
Lignin, the most abundant aromatic polymer in nature, is a valuable renewable resource due to its high phenolic compound content. Utilizing depolymerized lignin for the bioproduction of valuable industrial precursors such as muconic acid has garnered significant attention. In this study, several genetically modified strains of Pseudomonas putida were constructed to bioconvert vanillin and guaiacol
The Lyapunov exponent is a wide-reaching and useful tool for the analysis of chaotic systems. In this thesis, we go through the necessary mathematical and computational framework to extract both the maximum Lyapunov exponent and Lyapunov spectrum for the double pendulum system. An analysis of the maximum exponent through time and the validity of Liouville's theorem were conducted, showing good
Dividing wall columns are single shell distillation columns which are thermally fully coupled. DWC has the ability to create three product streams from one feed stream. A simulation of DWCs is hard due to the complexity of the system. Unfortunately, there is no good software package that can be used for simulations. Instead a detailed flowsheet with the right components and good arrangement over t
In this thesis, we study the Jarrow and Yildirim framework for inflation modeling and provide a new specification based on spread modeling which allows to calibrate the model to Zero-Coupons and Year-on-Year options jointly with convexity adjustments. We use this model to provide closedform formulas for options volatilities, convexity adjustments and Year-on-Year swaptions prices. Calibration resu
Denna uppsats behandlar den romerska lagen lex Aquila och dess roll i det svenska rättsväsendet i stort och dess påverkan på skadeståndsrätten särskilt. Den syftar till att definiera lex Aquilias regler och bakgrund. Syftet är även att visa när lex Aquilias regler tillträde Sverige och hur dom har tillämpats. Utifrån ovannämnda redogörs följande frågeställningar: Lex Aquilias uppkomst och innehållThe purpose of the essay is to examine the ancient roman law lex Aquilia and its role in the Swedish regulatory framework. The essay is focused on lex Aquilias influence on Swedish tort law. The purpose is to define lex Aquilias code and its historic background. It also treats in which time frame it started to impact Swedish law and how it has been applied. Based on the above the following questio
Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. Oily yeasts have several advantages in comparison to alternatives; their doubling
Processors grow more and more complex, even more so in the field of GPUs, where the instruction set, in general, is not publicly available. This enables them to change more rapidly than CPUs, since backwards compatibility is not an issue. In this thesis multiple approaches are investigated for code generation for a clause-based GPU. An optional pre-scheduler is implemented, together with two appro
The aim of this bachelor degree project is to design a modular luminaire with a longer lifespan, in order to reduce consumption. The project aims to explore how design can contribute to sustainable development by creating a durable and adaptable lighting solution. The luminaire is versatile and can either be hung from the ceiling, mounted on the wall, or placed on a table. It can be expanded
The efficiency of combustion engines is crucial for their future development, prompting researchers to explore various factors to enhance performance. Among these factors, exhaust gases hold significant potential. Typically, exhaust gases carry about 30-40% of the engine's energy, which often remains underutilized. Although technologies like turbochargers have made progress in recovering some
Digital integrated circuits are fundamental to modern electronic devices, with increasing design complexity requiring robust verification methods to ensure error free functionality. This thesis examines the critical role of formal verification in digital Integrated Circuits (IC) design, particularly during the architecture modeling phase. Using a state machine module that controls clock frequency
Computed tomography (CT) segmentation models are frequently used within radiotherapy treatment planning, but similar models are not available to the related imaging modality cone beam computed tomography (CBCT) due to the scarcity of labeled data from this domain. Such models could have multiple clinical applications whereby it is of interest to study whether the CT segmentation models can be adap
