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

Dust storms are meteorological phenomena that occur in arid and semi-arid regions, causing harm to the environment and human health. The frequency and intensity of dust storms have increased in recent years due to climate change and human activities. In response, various dust storm mitigation strategies were introduced, including land use management, afforestation, and mulching. The existing resea

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

För att generalklausulen i den svenska lagstiftningen mot skatteflykt ska kunna tillämpas krävs det att skatteförmånen som uppstår strider mot lagstiftningens syfte. Vad detta innebär är inte fullständigt klarlagt av vare sig lagstiftaren eller av Högsta förvaltningsdomstolen. Lagens syftar till att domstolen ska göra en analog tolkning och dess rättssäkerhet har därför varit omdiskuterad. Syftet For the general clause in the Swedish legislation against tax evasion to be applicable, it is required that the tax advantage that arises is contrary to the purpose of the legislation. What this means is not fully clarified by the legislature or the Supreme Administrative Court. The law aims for the court to make an analogous interpretation and its legal certainty has therefore been debated. The p

Predicting the stock market has been a longstanding topic of interest in financial research. It is regarded as a highly challenging but important task given the vital role the financial markets play in shaping the global economies. In this thesis, the goal is to predict the movement of the S&P 500 Index using machine learning methods. To this end, we apply two machine learning algorithms, rand

Malaria är en sjukdom som orsakas av encelliga parasiter. De parasiterna bärs av hon-myggor av arten Anopheles som främst befinner sig i de södra delarna av världen. Symtomen som upplevs av malariainfekterade människor liknar förkylningssymptom men även feber, illamående, frossa m.m. Infektionen sprids genom myggbett, sporozoiter sprids i blodet och hamnar i levern där de förökar sig vilket leder A molybdenum complex containing a chloroquinoline derivative has been synthesized; however, due to time restraints, neither X-ray diffraction nor testing of the drug has been accomplished. The identification of the complex relies solely on NMR results, which have also shown partial impurities. Therefore, for future improvements, it is suggested that flash chromatography is run after every step to

In the last 10 years, sustainability has been in focus and cities are being designed to prioritize sustainable alternatives. Today, narrowing the carriageway is used as an alternative to make way for sustainable alternatives in the existing street space. The purpose of this study is to investigate the consequences narrowing the lane can have on the lifespan of the road structure and what damage it

When in need to tell stories we often find ourselves using not only our words but also accompanying gestures, as well as pictures. However, what if we were to use only gestures to narrate? Would the stories we tell be clear enough to understand? The thesis investigates the potentials and limitations of pantomime, which consists mostly of gesture, for storytelling. Concretely, through a unique two-

Syreupptagningsförmåga är en bra indikator av kardiopulmonär hälsa, men be- höver speciell utrustning och är tidskrävande att mäta. Det finns sätt att upp- skatta syreupptagningsförmåga baserat på andra faktorer så som puls och accele- ration. Målet med denna masteruppsats var att undersöka om modeller som upp- skattar syreupptag baserat på accelerationsdata insamlad från sensorer i smartp- hones,Oxygen uptake is a great indicator of cardiopulmonary health but requires spe- cialized equipment and is time consuming to measure. There are ways to estimate oxygen uptake based on other factors such as heart rate and acceleration. The aim of this master thesis was to investigate whether models estimating oxygen uptake based on acceleration data collected from the sensors in smartphones, and step
