Bioplastics are a promising alternative for petroleum-based plastics that today is on high demand in our contemporary lifestyles. They are made from biopolymers such as polyhydroxyalkanoates (PHAs). Producing biopolymers from waste material feedstock using microbes increases profitability and environmental benefits as well as sustainability for biorefineries. Saccharomyces cerevisiae is a robust m
This thesis focuses on predicting the usage efficiency of e-scooters through the application of a Spatio-Temporal Graph Neural Network (STGNN). The predictions made by the STGNN will be compared with classical machine learning (ML) methods, including Random Forest (RF), Artificial Neural Network (ANN), and Linear Regression (LR). To facilitate the prediction of usage efficiency, the Time to Bookin
As technology progresses, it seems to become increasingly inevitable for everyday objects in our homes to incorporate advanced features, to increase functionality, convenience, and energy management. This master’s thesis presents the continuation of a Bluetooth lighting system, aiming to develop a comprehensive website solution for handling the provisioning and configuration of Bluetooth Mesh devi
Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. OSS systems cannot track the patients surfa
Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. For example, QSM of the articular cartilage of the knee has been suggested as a means to study the degeneration of this ti
This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-D
Renewable Energy Communities (REC) are seen as a way to promote energy justice and security and advance a democratic, socially-just energy transition. However, energy justice scholarship indicates that some social groups are not included in RECs. I conducted four semi-structured interviews with urban RECs in Germany to find out which communities are underrepresented and why. The feminist energy ju
Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficienc
In 2021, the Icelandic government stated that Iceland will implement an energy transition plan with the goal of becoming a 100% carbon neutral and fossil free nation by 2040, furthermore, that a doubling in renewable energy production was needed to reach that goal. This led to an upsurge of a discourse among stakeholders and concerned citizens about the future of Iceland. This thesis is an attempt
In this master’s thesis, different options to update the variant rank model used at the University hospital in Lund are presented. The variant rank model filters genetic variants from whole genome sequencing. This is done to identify potential causative variants in patients. Since the knowledge concerning these variants and rare genetic diseases grows rapidly, the model which filters said variants
Streamflow analysis helps us understand the availability of water resources in a region or a river. Accurate and timely streamflow monitoring is essential to improve our understanding of the hydrological cycle. Streamflow information is also necessary for many applications, such as irrigation planning, watershed management, hydropower products, flood control, and integrated water resources managem
Right-wing populism has become more and more prevalent in the political landscape, a trend especially observed in Europe. In the north, Scandinavian countries have seen a substantial rise in support for populistic, right-wing parties with Denmark and Sweden being two striking examples. In the respective countries, “Dansk Folkeparti'' and “Sverigedemokraterna” have been the most prominent e
Syfte: Att undersöka ifall det går att generera överavkastning genom att enbart investera i branscherna alkohol, spel, tobak och försvar. Detta genom att jämföra dessa investeringar mot indexet MSCI Europe och den etiska fonden SEB Ethical Europe. Metod: Med hjälp av programmet Thomson Reuters Datastream har fakta kring bolagen tagits fram och sorterats in utifrån branschtillhörighet. Denna data
Gastric ulcer is a common disorder in horses. A known potent inhibitor of gastric acid secretion is omeprazole. This thesis describes the study of omeprazole extraction followed by a high-performance liquid chromatography (HPLC) method for the quantification of omeprazole in enteric-coated pellets (raw material) and in oral paste (final drug product) for horses. The drug product is composed by a p
Denna uppsats behandlar förutsebarheten i påföljdsfrågan för psykiskt störda lagöverträdare. I Sverige har det i flera decennier funnits diskussioner kring de psykiskt störda lagöverträdarnas ansvar. Den nuvarande svenska regleringen är internationellt sett unik, då den inte innehåller ett krav på tillräknelighet. Syftet med uppsatsen är att utreda den svenska regleringen av psykiskt störda lagövThis paper discusses the predictability in sentencing of mentally disordered offenders. For decades there have been discussions in Sweden about the responsibility of mentally disordered offenders. From an international point of view, the current Swedish legislation is unique, due to the fact that it does not contain a requirement for accountability. The purpose of this paper is to investigate th
In most manufacturing companies, it is necessary to carry inventory to a greater or lesser extent in order to disconnect the activities in the supply chain that are not conducted at the same pace. This way, a smoother flow through the chain, from raw material extraction to arrival at the final customer of a finished product, is facilitated. However, different parts of a company often have conflict
Accurate wireless channel models are crucial to simulate the effect of radio wave propagation in a channel on wireless communication systems. By calculating physical processing effects that signal undergoes while traveling from transmitter to the receiver, channel models help to analyze performance of wireless systems. State of the art channel model such as WINNER and COST 2100 are able to model t
The interactions between airway epithelial cells (AECs) and dendritic cells (DCs) play an important role in the sensitization towards airborne allergens. Not much is known about the underlying mechanisms and novel in vitro approaches are needed, which include the different involved cell types in order to investigate what happens at the molecular level during sensitization. In this project, one aim
