Oxygen concentrators are relatively small medical devices that concentrates oxygen from the ambient air next to the patient. They are widely used in low resource settings and in the home health care. For larger hospitals in Sweden and similar countries however, the most common oxygen source is liquid oxygen and oxygen cylinders, delivered from an off-site supplier. Liquid oxygen is often not an op

Mobile robotics is an expanding field worldwide leading to the need for advanced path-planning algorithms that can traverse various environments. Current state-ofthe- art path-planning algorithms used at the Swedish Defence Research Agency, FOI, tend to be inflexible and parameter dependent. The parameters might need to be tuned for each new environment, which is a very labor-intensive process. T

This thesis presents a report of predicting latency in a 5G network by using deep learning techniques. The training set contained data of network parameters along with the actual latency, collected in a 5G lab environment during four different test scenarios. We trained four different machine learning models, including Forward Neural Network (FNN), Convolutional Neural Network (CNN), Recurrent Neu

This thesis will explore the use of AWS machine learning services that enable natural language processing (NLP). More specifically, this work will focus on sentiment analysis of product and service reviews written in Swedish. To find the most efficient solution to this task, the ready-made sentiment analysis tool available on AWS (Amazon Comprehend) was compared to custom-made solutions built on t

Theories on discourse accessibility and givenness suggest that nominal discourse entities vary with regard to how likely they are to act as antecedents to anaphoric expressions. Many factors are thought to affect the accessibility of a nominal entity in the mental model, including its morphosyntactic form and grammatical role. Moreover, previous research has shown that reflexive pronouns can be il

This study focuses on estimating the state of health (SoH) of a lithium iron phosphate (LFP) battery system, which is crucial for assessing the value and lifespan of new or used batteries in energy storage, grid support, and electric vehicle applications. A proposed method for determining SoH based on comparing useful and nominal useful capacities in Ah and Wh, as well as total and nominal capacit

The development and use of stretchable electronics is a relatively new research field. However, the use of these kinds of electronics could prove fruitful when seeking to improve medical sensors and equipment. Since the substrates and manufacturing methods used when making stretchable electronics allows them to be extremely thin, with a thickness in the μm range. At these thickness levels, the ele

Tveksamhet mot vaccin har tidigare undersökts både globalt och inom nationer, genom såväl demografiska och socioekonomiska faktorer som politisk och ideologisk orientering hos de personer som har erbjudits vaccin. Skillnader i vaccinationstäckning har föreslagits vara geografiskt strukturerat, kopplat till Covid-19 såväl som andra vaccin, och det finns flera exempel på sådan forskning där rumsligaGlobal as well as national vaccine hesitancy have previously been investigated using demographic and socioeconomic factors, as well as political or ideological orientations of the persons offered vaccinations. Variation in vaccine uptakes has been suggested to be geographically structured, in both Covid-19 and other vaccine contexts, and there are several examples of such research applying spatial

Unsafe food consumption is an alarming issue worldwide which is linked to the fatalities of two million people annually. Such unsafe food intertwines with the right to health of consumers in a way that every individual is ubiquitously a consumer at one point in their life and safe food is one of the determinants of the right to health. Hence, the right to safe food and the right to health of consu

This thesis aims to introduce the tools that are needed to understand — and historically led to the inception of — Hitchin systems. We lay out a basic theory of Hamiltonian systems on symplectic manifolds, and prove the Liouville-Arnold theorem, which states that integrable Hamiltonian systems admit coordinates in which their solution is basically linear. We then introduce a theory of holomorphic

Uppsatsens huvudsakliga syfte är att studera fenomenet digital detox i hur bloggarna uppmuntrar sina läsare till nedkoppling i den uppkopplade världen. Där bloggarna beskriver digital detox och deras erfarenheter, varför en digital detox är bra och tips på hur de och sina läsare ska lyckas med en digital detox. För att undersöka detta har vi valt ut fem stycken blogginlägg där vi med hjälp av en k

In this paper, we explore the practices independent artists use on social media. We address topics such as the democratization of the music industry and marketing on social media platforms. To gain a comprehensive understanding of these practices, we interviewed four independent artists. We also analyzed the artist's Instagram accounts using a lurking approach. Our focus will not lie on the co

The future of agriculture depends on healthy soils, but soils are degrading within dominant agricultural systems, also in Denmark. Pioneer farmers seek a sustainable transition towards soil-centered management. However, reinforcing feedback loops in current agriculture is blocking such a transition. Founded in emancipatory social science and critical utopian action research, this thesis, in collab

Conventional agrifood systems significantly contribute to environmental degradation. While Community Supported Agriculture initiatives (CSAs) may provide insights into alternative agrifood systems, few studies have investigated challenges to their engagement with prefigurative processes. Through a case study of nine CSAs in South-Holland, the Netherlands, this thesis explores the extent to which C

Emissions from road transport are one of the biggest health threats during the 21st century and are therefore being regulated with Euro standards. Part of the emissions from road transport originates from brakes and brake wear particle will therefore be included in the new standards. Brake system manufacturers will have to meet the new Euro standard and potentially reduce emissions from their prod

This project aims to bring more personal freedom to martial arts training. Following a classic product development process resulting in a product that enables users to work out on their own terms instead of being tied to a gym. The end result is a detailed prototype of a new innovative product that fills a market gap for versatile but portable martial arts equipment.

Meningsfull förändring är en central och djupt rotad strävan inom det psykoterapeutiska området. Terapeutens roll handlar om att hjälpa patienten att skapa förändring som är meningsfull för individen. Genom att mäta meningsfull förändring kan terapeuten se vilka interventioner som verkligen fungerar. Studien syftar till att utveckla och initialt utvärdera ett instrument för att mäta meningsfull föMeaningful change is a central and deeply rooted endeavor within psychotherapy. The study aims to develop and initially evaluate an instrument to measure meaningful change in psychotherapy. The therapist's role is to assist the patient in creating change that is meaningful to the individual. By measuring meaningful change, the therapist can identify which interventions are truly effective. The

System in Package (SiP) is often used in wireless technologies where different active and passive components can be integrated under the same substrate, resulting in smaller devices and lower costs. The design of the embedded antennas in system in package is a challenge from various points of view. Since system in packages are often used when a small module is needed, and as the size of the module
