This thesis defines the finite projective plane and the affine projective plane. A method of construction is defined for the field planes by extension of the affine plane constructed from the vector space over a finite field. The thesis explores for which orders planes can and cannot be constructed, in particular, for the prime powers there exist planes. For n=6 a computer search is conducted usin
En mer flexibel och effektiv arbetsmarknad med olika lagregleringar har lett till en arbetsmarknad där allt fler bemanningsföretag hyr ut arbetstagare, ofta under kortare perioder. Att vara uthyrd arbetstagare ses ofta som en osäker anställningsform. Denna uppsats ämnar att undersöka konsultchefers syn på osäkra anställningsformer. Syftet är att undersöka konsultchefers perspektiv på osäkra anstäl
The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. Consequently, one of the algorithms is selected a
This essay analyzes the differences and similarities in the most recent EU and U.S. elections. A narrative analysis is employed, and the theory is based on a social constructionist approach to knowledge. An analytical framework is developed comparing categories/contents of right-wing populism and democracy in relation to the narrative elements building on Labov och Waletskys (1967). The study show
To reduce pollution and green house gas emissions associated with plastic production and waste, biobased production of the biodegradable plastic, polyhydroxybutyrate (PHB), is suggested to be a good substitute to petrochemically derived plastics used in foodstuff packaging. However, bacterial production of PHB has proven costly and production with plants occurs at the expense of arable land. Oleag
How we as viewers emotionally connect and interact with art and other aesthetic experiences is a widely debated topic in the art historical discourse. Following German aesthetician and philosopher Robert Vischer’s theorisation of the concept of Einfühlung during the 1870s, the empathic discourse has intrigued and engaged thinkers throughout centuries. With the discovery of mirror neurons in the hu
Antimicrobial resistance (AMR) is a growing problem worldwide as more drug-resistant bacteria are identified. However, resistance is comparably rare against antibiotics that target the cytoplasmic membrane. Membrane thickness is an important factor for the mode of action of these antibiotics, and difficult to study. Thus, constructing a biosensor to measure membrane thickness in vivo is of great i
Sustainability transition research investigates why the necessary change towards more sustainable patterns of consumption and production has not yet been achieved and how it can be accelerated. Taking into account the complexity of the globalised dynamics underlying today's sustainability challenges, it has been suggested that the existence of global regimes limits the possibilities for change
Uppsatsen utforskar vilka historiedidaktiska perspektiv man kan tillämpa på de populära Assassin's Creed-spelen, med fokus på Assassin's Creed II och Assassin's Creed: Brotherhood. Historiebruk, historiekultur och historiemedvetande, vilka tillsammans bildar den historiedidaktiska teorin, utgör de teoretiska underlagen. Det metodologiska tillvägagångssättet är en kombinerad text- och b
Current post-carbon transition trajectories are primarily based on a belief in technical solutions wherein considerations of the citizens’ role in collective mobilisation and transformation are largely overlooked. To this end, the thesis seeks to understand how citizens can become active agents of change within transition efforts and how their political agency can be empowered accordingly. This, b
There are many advantages with the development towards Integrated Circuits (ICs) with smaller, faster, and more transistors. However, tighter margins lead to a need of on-chip instruments to test, tune, and configure. These on-chip instruments, which can be in the range of thousands per IC, must be accessed through the life-time. However, access is challenged by complex system hierarchies. When IC
The aim of this study was to examine pollution-induced community tolerance (PICT) of biofilm communities induced by chemical mixtures, characteristic of agricultural aquatic environments. Additionally, the use of biofilms as a natural passive sampler was investigated. In situ biofilms grown on artificial substrate for 4 to 6 weeks from sites located in agricultural areas were used to conduct a PIC
In this project, I start by addressing the issue of the creativity decrease that happen within children when they start school. I wanted to emphasize the importance of creative play to develop problem-solving skills. After I ran some user tests, my project took a new turn and instead I started designing a board game for an older target group. The aim of the game is to improve the visual comm
The many cases of malignant melanoma and the following relapses after standard-of-care treatment demands inventions on finding new treatment to this cancer disease. One of the reasons for reduced clinical response in melanoma is the downregulation of tumor specific antigens which results in decreased tumor recognition, followed by tumor escape and progression. This study investigated the potential
