Sedan 1970-talet har antalet rapporterade cancerfall dubblerats, dels på grund av förändrade levnadsvanor och dels på grund av bättre screeningmetoder som upptäcker cancern i tidigt skede. Tidig upptäckt av cancern i kombination med utvecklad cancerbehandling har bidragit till att risken för att avlida av cancer har minskat. Cancerbehandling sker huvudsakligen genom operation, strålbehandling elle
Wireless Power Transfer (WPT) technology has experienced phenomenal success in the application of wireless charging of smartphones. With the Qi Specification becoming the dominant standard, wireless charging's convenience goes beyond cable-free charging to facilitate interoperability between chargers and devices from different vendors. For wireless charging to operate correctly, the power tr
Failure often captures public attention, especially in an intelligence context were the consequences can be devastating and the successes are rarely visible. Understanding failure is important if we are to prevent it and both the field of organizational theory and the field of intelligence have been interested in the nature of failure. This study aimed to further the understanding of intelligence
Polymers of N-substituted glycine (NSG) or as they are also called, peptoids, have shown potential in biomedical applications due to proteolytic resistance, among other interesting properties. In this thesis project, two synthetic routes have been performed and evaluated to achieve a better understanding of large-scale syntheses of peptoids as a bioinert coating for nanoparticles. The primary fo
Multiple modern methods of statistical feature extraction and machine learning are applied to classification of encoding and retrieval of episodic memories us- ing electroencephalogram (EEG) recordings. Raw data, different time-frequency methods, and multiclass common spatial patterns are used for statistical feature ex- traction. For each type of feature extraction multiple machine learning algor
Since the purchasing expenditure of many companies is such a large part of the total cost and 99,8 % of companies are classified as Small and Medium Sized Enterprises (SME), one might expect that theories on purchasing strategy would not only be conducted for large companies but also SMEs. In order to fill this gap in theory, this thesis aims to create a purchasing strategy framework for SMEs in t
Many people today possess a private digital photo collection. Such collections are often just chronologically sorted. One way to make photo browsing more interesting would be to suggest semantically related photos to a currently viewed photo, and if, in addition, such a relationship could be justified in words, that would create extra value for the user. To find a solution to this problem, the ap
There is a lot of discussion going on how to adapt to the changing climatic conditions, especially in countries where financial resources are limited. The built environment has been identified as a key area of intervention. As disasters, such as typhoons, can devastate entire cities, it is essential that the most important buildings in these cities, the lifelines so to speak, are resilient and can
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
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
Infant mortality is a powerful indicator to measure the health and social status of a country. The purpose of this study is to identify the important factors that in uence the infant mortality of Bangladesh. Moreover, this study suggests the government and the policy makers to improve the health and social sectors for reducing the country's infant mortality signicantly. To investigate the impo
Gendered violence against woman and children has been in existence and predominant in various societies for a long period of time with its intensity varying from one factor to the other. Many nations around the world including Ghana in West Africa have measures and directives to mitigate of the persistent social menace and possibly eradicate it towards sustainable welfare and development for indiv
Climate change is a long-term challenge that requires urgent actions. An increased amount of greenhouse gases in the atmosphere, causing changes in the climate system such as melting glaciers and extreme weather conditions, are correlated to economic growth. To mitigate climate change, there is a need to evolve efficient strategies to reduce greenhouse gas emissions from companies within all branc
