Formula Student is an international inter-universities competition about designing and building a single-seater racing car. One of the most important parts in a car is the suspension system, from the tires to the shock absorbers. This Master Thesis’ report goes through all these parts, looking to theory, different design options, the constraints (rules, economical, packaging, etc) and the final de
The Republic of Moldova is celebrating 20 years of independence and is still almost completely dependent on energy imports from the Russian federation. Renewable energy is in its infancy despite a climate that is well suited for solar and wind energy with 2,300 sunshine hours per year and measured wind speeds up to 8.5 m/s. Moldova has a history of wine production and wide spread usage of more tha
The major problem when developing primers and probe sets for detection of HIV-1 is its high genetic variability and strong ability to mutate. HIV-1 is divided into four groups, M, N, O, P based on genetic similarities, and there are more than 70 different circulating recombinant forms. The aim of this master thesis was to develop new primers and probe for a novel quantitative PCR analysis method f
Antalet personer som lever med en kronisk sjukdom ökar, detta som en konsekvens av bland annat en snabbt ökande äldre befolkning. Kroniska sjukdomar orsakar inte bara mänskligt lidande, utan är också en ekonomisk börda för samhället. För att lindra lidandet och minska kostnaderna kopplade till kroniska sjukdomar kan användandet av digitala hälsotjänster vara en möjlighet. För närvarande är förväntThe amount of people living with chronic diseases is increasing. Chronic diseases do not only induce human suffering, it is also an economic burden on society. To ease the suffering and reduce the costs connected to chronic diseases, the usage of digital health services might be a possibility. Currently, the expectations on such services are high, but not met. To better meet the expectations, this
This degree project aims to develop standard methods for determination of the size distribution in different samples using laser diffraction, as well as to create methodologies for development of new methods for unknown samples. The size distribution is crucial to understand for pharmaceutical products since it affects properties such as the stability and bioavailability of the product. A way to
The beverage packaging industry is growing rapidly, driven by urbanization and changing lifestyles. Demand for packaged beverages with extended shelf life is driving sales of products with superior barrier properties, due to the high environmental impact of food waste compared to packaging waste. Despite progress, packaging waste represents more than a third of total waste. Thus, milk and plant-ba
The thesis explores the decision-making process of sustainable entrepreneurs for securing external funds by adopting the “triple bottom line” research perspective (Hall et al., 2010; Sarango-Lalangui, 2018). It delves into how sustainable entrepreneurs assess and exploit funding opportunities while balancing their economic and non-economic goals. The research addresses two primary questions: what
The aim of this study was to deepen the understanding of how community-based water management approaches facilitate sustainable and collective action (SCA) in the context of increasing water insecurity in Costa Rica. Applying a qualitative approach, based on fieldwork in Guanacaste, Costa Rica, including semi-structured interviews and a digital community survey, the study uncovers facilitating fac

In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. The Swedish Research Council is supporting a project called Solar Food: Reducing Post-Harvest Losses Through Improved Solar Drying, which aims to create a low-cost solar
In recent years, battery energy storage systems (BESS) have gained prominence as a key technology enabling much needed electricity grid flexibility while simultaneously providing distinct value to its end-users. With the anticipated increase of residual value holding used batteries from mobility applications entering the market, more and more companies are looking to construct BESS offers around t
High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical app
This thesis aims to explore the issue of trademark squatting and its solutions in the EU and China. Trademark squatting is a form of trademark infringement that occurs when individuals or entities register trademarks in territories where they do not have legitimate business operations, taking advantage of the "first-to-file" systems. If trademark squatting is permitted to persist, it has
Neutrons have a magnetic moment that interacts with magnetic fields. This has been put to use to study magnetic materials. Polarised neutron imaging (PNI) is one such application that allows the observation of, for instance, magnetic domains and domain walls inside a sample. To facilitate a PNI experiment, the neutron beam from a neutron source needs to be polarised, meaning that the magnetic mome
To mitigate greenhouse gas emissions resulting from the combustion of fossil fuels in conventional transportation—including vehicles, ships, and aircraft—a wide range of alternative energy sources have been explored, such as liquefied natural gas (LNG), methanol, liquefied petroleum gas (LPG), biomass, solar energy, hydrogen, fuel cells, and batteries. Among these, battery electric propulsion syst
The main goal of this investigation is to determine the optimal number of cashiers to be employed in a first-in-first-out (FIFO) queuing system, based on the number of customer arrivals, the average revenue generated per customer, and the rate at which each customer abandons the queue, referred to as the reneging rate. This is done by using continuous-time homogeneous Markov Chains to model the ar
This thesis examines how female-targeting fintech firms can internationalize in ways that genuinely promote financial inclusion for women. Conducted as an exploratory interview study with Female Invest, it builds on the broader observation that gender remains largely absent from fintech’s outlook. The study addresses two key research gaps. First, financial inclusion efforts often overlook how cult
To reduce reliance on energy-intensive, chemically synthesised nitrogen sources in microbial cultivation, we investigated the integration of the nitrogen-fixing bacterium Azotobacter vinelandii into a bioconversion process with the recombinant yeast Saccharomyces cerevisiae. Our objective was to develop a more sustainable approach by utilising biological nitrogen fixation to supply ammonium direct
100 000 elderly fall each year, costing the healthcare system up to 750 million SEK. Beyond the financial part, these accidents could lead to serious injuries such as head trauma or hip replacements, and in the worst case, even death. This project aims to find a preventive technique that will make life easier for the elderly while saving money and resources for society. The aim is to gather data
