In products with multiple, movable components it is often important to know the position of them. Such an example is to localize the different optical modules used within a multidirectional surveillance camera. This thesis explores the feasibility of using ultrasound distance-measuring technology for that particular application. Various methods and technologies were examined before developing a co
Hur speglar användbarhetsproblem den upphandlade kravställningen? Vad är det viktigaste att kravställa inom digitala verksamhetssystem och hur görs det på bästa sätt? Det är frågorna som detta projekt har undersökt genom att utvärdera ett digitalt verksamhetssystem i två olika kommuner i Sverige. Genom intervjuer, enkätundersökningar, och utvärdering av upphandlingsdokumenten undersöktes hur kommu
Quadratic time-frequency representations are indispensable tools in non-stationary signal analysis. Thus the incorporation of such tools into signal detection is pre- dicted to yield more sensitive detectors especially in the context of non-stationary signal detection. We elucidate the theory of time-frequency representations and signal detection then implement a time-frequency detector using Wign
This master thesis analyses the future electricity mix in Sweden with a focus on 2035, 2045, and 2050. The study is done with regards to reaching the climate goals in Sweden, and to reach net zero greenhouse gas emissions by 2045, and thereafter have negative emissions. The thesis analyses political, economical, social, and technological aspects in a PEST-analyse for the power sources in the curre
Jag älskade arkitektskolan. Därför blev mitt exjobb att rita ett Kreativotek, som ett bibliotek, men för kreativt skapande. En ny typologi i staden där kvalitéerna med att vistas i en kreativ miljö (som en arkitektskola) blir en publik funktion i en urban kontext. En samling av ateljéer och verkstäder - Ankan, Räkan, Grodan, Krabban, Laxen, Hajen och Tigern - bildar kakbuffén Malmö Kreativotek. C
Global warming and climate change is projected to cause intensified extreme weather events. Food production is threatened by this and crop yields have shown to be negatively affected by extreme weather events. This study examined the correlations between extreme precipitation and temperature and crop yield of spring barley in Säby in Uppsala, Sweden in 1981-2021. Crop yield of spring barley was co
Advanced melanoma has for long been associated with poor prognosis. Recent advance- ments have improved outcomes; however, many challenges are yet to be overcome. Targeted therapy has in recent years been a good option for patients. Despite positive early responses to the treatment, tumours often grow resistant to these therapies over time rendering them ineffective. The development of resistance
The advent of new technologies for single-cell RNA sequencing analyses has resulted in the discovery that the myeloid compartment in the tumor microenvironment (TME) is far more complex than previously appreciated, and that intrinsic and extrinsic factors in the TME highly influence the immunosuppressive or active states of these cell types. There is now a need to develop multiplex assays to ident
Glycoprotein 2 (GP2) is a glycosylphosphatidylinositol (GPI)-anchored protein primarily produced by pancreatic acinar cells. It is expressed on M cells and can interact with the type 1 fimbrial adhesin (FimH), a component of type 1 pili found in gram-negative bacteria e.g Salmonella. It shares homology to Tamm-Horsfall protein (THP) which has been shown to have antibacterial effects and can also i
Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), is an inflammatory condition with high clinical relevancy, causing intestinal inflammation, diarrhea, and an overall impact on the quality of life. In some IBD patients, autoreactive antibodies against the pancreatic-derived glycoprotein-2 (GP2) have been identified, highlighting a break in immune toleran
Automation and robotics have been widely integrated across various industries, yet the building sector has not seen significant evolution over the last few centuries. This thesis presents a concept for integrating automation at construction sites, specifically for the assembly of wooden prefabricated walls. When working with wooden prefabricated house elements the sizes are typically large, 6-10 m
The efficient allocation of flexible resources, such as grid batteries and wind parks, across multiple energy market auctions, is pivotal for maximizing socio-economic welfare, interpreted here as profits. This study explores various optimization methods, including Linear Programming, Integer Linear Programming, Robust Optimization with Linear Programming, and Robust Optimization with Integer Line
Arbetet undersöker vilken roll musik har i att förändra samhället, vad som utmärker musik som påverkar samhället, och på vilket sätt musiken påverkar. Detta görs med hjälp av en historisk grund och genom intervjuer av tre personer som har en inblick i att påverka genom musik. Målet är att arbetet ska ge en inblick i hur man kan påverka genom musik, för att sedan själv kunna börja påverka genom detThe essay examines what role music have in changing society, how music that affects society is different, and in what way the music makes a change. This is done through a historical base and through interviews with three people with an insight into influencing through music. The goal is that the essay will give an insight into how one can influence through music, so that the reader then can start
Kemira Kemia AB produces a water treatment chemical named ”PIX-Sulfate”, where “PI” stands for “poly iron x”, and the “x” represents a conjugate ion, such as chloride or sulfate, in this case, sulfate. The main process for producing PIX Sulfate at Kemira’s plants today is to dissolve magnetite in diluted sulfuric acid and to oxidize the resulting liquid using oxygen. Currently, this process is car
Biomimetic models inspired by natural [FeFe] hydrogenases have good potential for clean hydrogen production. Improving these models to increase their efficiency is a challenge that requires further research and development. This study aims to explore the catalytic behavior of ruthenium-based clusters in proton reduction to create hydrogen production catalysts inspired by natural hydrogenases. Four
This study examined the relationship between adult attachment dimensions and life satisfaction among expatriates residing in European countries, with a particular focus on the challenges of social isolation and cultural adaptation. It hypothesized that expatriates with secure attachment styles were more likely to report higher levels of life satisfaction compared to those with avoidant or anxious
7 § LAS, som tidigare angav att en uppsägning ska vara sakligt grundad, har ändrats på så vis att en uppsägning ska grunda sig på sakliga skäl. Ändringen innebär att vid uppsägningssituationer som hänför sig till personliga skäl ska fokus numer främst ligga på avtalsbrottet. Den framtidsprognos som tidigare gjorts kring en arbetstagares lämplighet ska inte längre göras och en arbetstagares intress7 § of the employment protection act (LAS) was recently changed when it comes to what is required to dismiss an employee. The change means that when an employee is dismissed based on personal reasons, the focus will primarily be on the employee’s breach of the employment agreement and the severity of the breach. There will no longer be any consideration of the em-ployee’s interest in keeping their
Purpose: To get a clearer picture of the structure and evolution of our Galaxy, astronomers are trying to reach further and further beyond the Solar neighborhood with their observations. The dust obscuration towards the center of the Milky Way necessitates the use of infrared wavelengths for this, and cold giants provide a particularly bright and thus useful target. However, any methods for analyz
We aim to introduce to the concepts and constructions in Auslander– Reiten theory, and to prove the Auslander–Reiten Theorem. This involves introducing certain concepts, such as the Yoneda extension groups, which we equip with a vector space structure. We define projective resolutions and presentations, and their dual con- cepts. We prove that the extension group can be constructed using a project
This thesis focuses on the optimization of a dual-motor powertrain for an electric vehicle known as the LEVKART, a lightweight four-wheeled vehicle developed for both indoor and outdoor usage. The study examined the effect of different battery voltages, specifically 36 V, 39.6 V, and 43.2 V, on the vehicle’s performance. The main focus lies on reducing the energy consumption and increasing the ran
