Immersing a user in life-like extended reality (XR) scenery using a head-mounted display (HMD) with a constrained form factor and hardware complexity requires remote rendering on a nearby edge server or computer. Millimeter-wave (mmWave) communication technology can provide sufficient data rate for wireless XR content transmission. However, mmWave channels exhibit severe sparsity in the angular do
Introduction: Older people with intellectual disabilities (ID) have higher levels of comorbidities and overall healthcare utilization than the general population. A known healthcare need would imply high levels of planned healthcare, while unplanned healthcare could be a sign of unmet healthcare needs. Thus, to understand if older people with ID are receiving the healthcare they need, different ty
The temporal aspect of groundwater vulnerability to contaminants such as nitrate is often overlooked, assuming vulnerability has a static nature. This study bridges this gap by employing machine learning with Detecting Breakpoints and Estimating Segments in Trend (DBEST) algorithm to reveal the underlying relationship between nitrate, water table, vegetation cover, and precipitation time series, t
Pharmaceutical companies spend hundreds of millions of pounds on marketing/R&D-related payments annually to healthcare organisations and healthcare professionals. UK pharmaceutical industry self-regulatory bodies require member companies who sign up to their code of conduct to publish details of their payments. They are also required to publish the methodologies underlying these payments, name
Evaluating the (Formula presented.) scaling function of elastic proton–proton ((Formula presented.)) collisions from recent TOTEM data at (Formula presented.) TeV and comparing it with the same function of elastic proton–antiproton ((Formula presented.)) data of the D0 collaboration at (Formula presented.) TeV, we find, from this comparison alone, an at least 3.79 (Formula presented.) signal of od
In this study, a mathematical model was developed to simulate the jet and plume behavior in order to determine the optimum discharge conditions for different scenarios. The model was divided into two sub-models, describing respectively the near and intermediate field properties of the discharge for different inclinations and bottom slope. The lateral spreading and electrical conductivity was also
The Sustainable Development Goals (SDGs) build on the Millennium Development Goals (MDGs) and aim to promote sustainable global development by addressing poverty, inequality, and environmental sustainability. Among the key objectives of the SDGs, Goal 6 targets universal access to safely managed drinking water and sanitation by 2030, recognizing the critical link between water, sanitation, hygiene
Groundwater is the general source of drinking water in the Shimabara Peninsula, Nagasaki, Japan, and consequently, occurring nitrate nitrogen (NO3-N) pollution in the groundwater is a significant problem. Although various countermeasures have been implemented, nitrate nitrogen concentrations remain serious. Therefore, it is necessary to evaluate effects of different potentially effective counterme
The sun is an important reason to why there is life on earth. To be able to predict future solar activity it is important to uncover past solar activity and its cyclicity. This thesis investigates the solar activity throughout the past 2000-years to the beginning of 21th century. Diagrams which contain relevant data from radionuclide and sunspot records have been constructed to get a better overvi
The risk for drinking water scarcity does not only concern developing countries and arid places. In its 2023 report, the Intergovernmental Panel on Climate Change has identified water scarcity as one of Europe’s key risks out of five in the foreseeable future. Sweden experiences water shortages more and more frequently during summer, and the need to protect groundwater resources is imperative. In
During the 20th century storm damage in Sweden has increased as a consequence of how the forest has been managed, an increased proportion of forest and older tree stands. The increase of storm damage has consequences for the regional economy, infrastructure, foresters, and the society. At the same time the climate is gradually changing, which means increased temperatures and higher precipitation r
Customer Support is usually an expensive service for a lot of companies. At Telavox, a majority of the support tickets are sent via e-mail. A support ticket is sent by a customer, containing a request for support. Support tickets from customers could reveal valuable information. Additional insights can be given by labelling the tickets. Today, employees at the customer support department at Telavo
In vehicles there are many issues involving the safety and performance. The safety issues are often regulated by governments, whereas the performance by the customer. One solution to both these issues is to take use of an all-wheel drive system, where a coupling engages and disengages driving axles when needed. Such a solution will, through added traction and stability, increase performance and sa
With the surge of open banking, there is a large increase in applications based on transaction data. Therefore, there is a need for being able to extract important information from Swedish transaction descriptions in a structured way. We designed models for named entity recognition on transaction descriptions that can identify and classify organizations, locations, persons, payment providers (e.g
Speech is an important way of communication all over the world. The speech information is encoded both aural and visual. More than 1.5 billion people have hearing loss and for those the visual information is even more important than for people with normal hearing. Lip reading is therefore an important research topic. In this master thesis, machine learning algorithms were used to identify speech a
