Evaluation of Convolutional Neural Networks for Image Quality Classification based on Synthetic Data

In camera production the image quality is of utter importance. Several tests during the production ensure this high quality. In this thesis the possibility of creating a final test, that classifies the image quality with the help of machine learning, specifically convolutional neural networks, was investigated. The data used was made up of synthetic, simulated images with commonly observed quality

Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

En tredjedel av Sveriges årliga växthusgasutsläpp kommer idag från transportsektorn, vilket innebär att stora förändringar behöver ske om målet om nettonollutsläpp vid 2045 ska nås. En viktig åtgärd som diskuteras i denna kontext är en ökad elektrifiering och en lösning som har möjlighet att bidra i denna omställning är elvägssystem, där elfordon laddas dynamiskt. En typ av konduktiv elvägsteknik One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where ve

Syftet med studien var att beskriva kvinnors upplevelser av mammografi

Investigation of a Quark Production Process

Quark is a dairy product that has existed for a long time. However, it has grown in popularity during the last years due to the fact that it is often portrayed as a healthy alternative in the dairy section. There are no regulations connected to the manufacturing process of quark. At a specific dairy company, there is a desire to understand and optimise the quark production to obtain a consistently

Covid-19 pandemin har haft stor inverkan på alla delar av världen och har bidragit till att människor har varit tvungna att ta livsavgörande beslut. Det finns även individer som själva har valt att gå en annan väg i livet och tagit ett livsförändrande beslut. Vetenskapliga artiklar har påvisat resultat av att människor har själva valt att säga upp sig men även ökat ansökningar för organisationer u

An Archaeology of the Invisible? Tracing Poverty and its Ideology in the Viking Age and Urban Settlements

Publications have recently drawn attention to archaeology’s historically predominant focus on prestige items and the elite, highlighting the need for a greater focus on society’s lower classes. A few studies have discussed how, or even whether poverty can be addressed in historical archaeology. However, the phenomenon has not seen the same attention in Viking Age studies, despite the great deal of

Strategic Investment Conceptualization: The power of experience and knowledge in the programming of decisions

The purpose of this paper is to investigate one of the seven characteristics proposed by Northcott and Alkaraan (2007): the characteristic of non-programmability. This paper responds to the call for a nuanced understanding of how companies are programming strategic investment decisions (Alkaraan, 2016, p. 520). The purpose is fulfilled by conducting multiple case studies. The data collection metho

A study of the s-step biconjugate gradient method

In this thesis we will examine how to solve linear systems using the s-step biconjugate gradient algorithm, which is an iterative method based on the Krylov subspaces. It is useful especially when we have a large and sparse matrix. We begin looking over the biconjugate gradient algorithm (BiCG), in order to understand how to construct the s-step BiCG algorithm. We will go through some numerical ex

RoboVac - Ascender

For my bachelor thesis, I wanted to explore and develop a new kind of robot vacuum cleaner. A robot vacuum cleaner that can climb stairs. Not that there is a big need for it for us to function as human beings. But to make the already established robot vacuums go even further. Simply to make time for more important moments of the user’s life. During my project, I researched and evaluated di
