What determines whether a change is meaningful or not, and how can it be assessed? Distribution-based methods of assessing meaningful change focuses on statistical significance, while anchor-based methods use other ways of measuring the same construct as the original scale (e.g., PHQ-9), such as expert assessments or other rating scales. This study intends to introduce and validate a novel way of
I takt med att världens befolkning växer ökar även mängden genererat hushållsavfall, vilket utgör en betydande påverkan på miljö och samhälle. Under 2018 genererades cirka 2 miljarder ton avfall globalt, en siffra som förväntas stiga till 3,4 miljarder ton till 2050. En stad som på senare år har gjort stora framsteg inom avfallshantering är Rwandas huvudstad Kigali, känd som Afrikas renaste stad. This master’s thesis explores a Waste-to-Energy solution for Kigali, specifically focusing on the Mpazi Rehousing Project. Kigali faces challenges with Solid Waste Management (SWM) despite its reputation for cleanliness and efficient urban planning. It aims to transform biowaste into biogas, contributing to sustainable urban development and reducing waste at Nduba landfill. The research addresses
Poly- och perfluorerade alkylsubstanser, även kallade PFAS, är en grupp av kemikalier som har använts i ett flertal olika typer av produkter, bland annat brandskum. Dessa ämnen är särskilt problematiska eftersom de är svårnedbrytbara, vilket innebär att de kan finnas kvar i miljön under lång tid efter ett utsläpp. De kan också ha en relativt hög rörlighet i mark- och vattenmiljön, vilket innebär aPer- and polyfluoroalkyl substances (PFAS) is a group of synthetic organic compounds that has been used in a wide range of products, including fire extinguishing foam which represents the greatest source in Sweden. Their chemical properties make them toxic for humans and most living species, although research is still on-going to determine the specific toxicity of each compound in the family. A la
Wilhelm Röpke was a german economist best known as one of the founders of ordoliberalism. After the second world war Röpke was instrumental in rebuilding the German economy, and he is therefore most of all known as an economic thinker. This thesis, however, is centered around his sociological and political thoughts, as well as his ideas on the economy. It examines the ideas presented in his 1941 w
Pollution and its impact on the environment is one of the greatest problems facing humanity today. Since the building sector is responsible for 40\% of the total carbon dioxide emissions, it is important to investigate the sector to see how emissions can be reduced. Due to timber having a smaller impact on the environment compared to steel and concrete, it is of substance to investigate the possib
Prebiotics are complex carbohydrates that are selectively fermented by beneficial gut bacteria, resulting in the production of health-promoting metabolites, such as organic acids like lactic acid, acetic acid, intermediates for butyrate and propionate. Baobab (Adansonia digitata) fruit contains many small seeds, often used for oil production. It’s by-product, baobab seed press cake, is rich in lig
High Tech security solutions refer to advanced and innovative technologies designed to protect assets, data and individuals from various threats. These systems offer benefits that traditional security measures cannot match. Examples of high Technology security solutions include Biometric Access Control that uses fingerprints, iris and facial recognition, Surveillance drones with cameras for monito
This project is an exploration of what product longevity is, the role of the user and how to design for a desired behaviour. This project is conducted through two parts. The first part aims to learn from professionals in the field through a study trip to Stockholm and Östersund, whereas the second part presents a chance to portray these findings through the development of a physical object in co-o
In this thesis, a fault detection and diagnosis system is developed for the Crazyflie 2.1 unmanned aerial vehicle. Different types of faults are investigated and suitable methods and tests are implemented. The system is mainly developed for the lighthouse positioning, but the tests and methods are generic and suitable for other parts of the Crazyflie eco-system. For the faults investigated, differ
The “Endangered Oddballs” project addresses the pressing issue of biodiversity loss by using sculptures as a medium for raising awareness and funds for endangered species. Using a combination of artistic interpretation and scientific research to create a series of figures that accurately represent lesser- known endangered animals. The research method involves close observation and study of each sp
More and more cities are being marketed as green. Malmö has since the late 90ies transformed from a city in great economic downturn to being internationally known for its green profile, attracting companies, tourists and professional visitors. Despite its reputation of being the city of parks Malmö has the second to least green space per person in all of Sweden’s urban areas, and it’s shrinking. T
Large Language Model-based systems, such as ChatGPT, have gained tremendous popularity in recent years. These computational systems generate natural language text in a conversation-like manner, relying on “deep learning” to produce statistically probable language patterns. Many studies have focused on the potentials of such systems, including tasks that are intended to test for natural language un
Facing the limitations of current wildfire management practices, increasing attention has been paid to indigenous wildfire practices that use fire for ground fuel reduction. This study investigated the cooperation and association between indigenous and non-indigenous peoples for current wildfire management, with a focus on prescribed burning, to provide a comprehensive review of activities. Throug
De livsnödvändiga molekyler som kroppen behöver är många. Vissa kan vi själva tillverka, andra behöver tillföras via kosten. Kolhydrater (socker) är ett exempel på dessa livsnödvändiga molekyler. Dess primära uppgift är att förse kroppen med energi, men de har även många andra viktiga egenskaper; såsom cellulär uppbyggnad och cell-kommunikation. Kolhydrater är byggstenar till en rad olika bio-moleProtecting groups, or PGs, are important in synthetic organic chemistry. However, protective group free chemistry, i.e. to manage reactions without the use of traditional PGs, has recently caught the attention for the entire field of chemistry. When working with sugar molecules, it is important to know that the molecule contain several hydroxyl groups. It is thus essential to make sure the sugar
ABSTRACT Background: In the growing body of knowledge on how human environment impacts population health, the transport sector is observed to occupy strategic position. However, the transport corridors equally serve as sources of socio-economic challenges. Such is the case of the transport sector’s contribution to the HIV/AIDS epidemic. In this respect, truckers are observed to carry a disproporti
With the growing market for enhanced security combined with recent advancements in robotic technology, the possibility of integrating these two fields is of considerable interest. While traditional surveillance relies on mounted cameras and scheduled guard tours by humans, the next step would be to use a robot to complement a person in such systems. This project explores the integration of autonom
Mobile communications have evolved with the commercial deployment of 5G and initial studies of 6G. New solutions and innovative technologies are being incorporated to reach the target requirements. One of the key technologies in mobile networks is massive multiple-input-multiple-output (MIMO). Increasing the number of antennas offers significant benefits in coverage, reliability, and spectral effi
User Equipment (UE) grouping entails categorizing multiple UEs, including mobile phones or smart devices, according to defined criteria. It provides valuable insights for applications to optimize network resources, enhance handover procedures, and improve user experience. This study investigates UE grouping in a Fifth Generation (5G) Time Division Duplex (TDD) system based on Uplink (UL) Sounding
The rising influence of the far right in Europe and the advance of the climate crisis constitute intersecting trends. The AfD in Germany is no exception in gaining discursive and political power in this context of uncertainty. Particularly in the realm of social media and TikTok, the AfD receives unproportionate popularity and visibility, which enable the spread of its ideology-laden discourse and
