With future technologies and Industry 4.0, the need for robust and accurate positioning to optimize productivity and industrial operations increases. The previous positioning methods using triangulation or angle-of-arrival are not good enough, especially not for clutter-dense factories with poor line-of-sight conditions. For this thesis project, a convolutional neural network model was trained t

Euklidisk geometri var den första ge- ometrin som man stötte på i grundskolan, allt från trianglar till cirklar. Samtidigt fick man lära sig att inget av dessa objekt finns i verk- ligheten. Det var inte förrän Benoı̂t Mandelbrot (1924-2010) insåg att många naturfenomen är så oregelbundna och komplexa att de inte kan beskrivas med euklidisk geometri. I detta sam- manhang verkar Mandelbrots citat vLet $\dim_H(\mathcal{J}_\epsilon)$ and $\dim_H(\mathcal{J}_{i\epsilon})$ denote the Hausdorff dimension of the Julia set of the polynomials $f_\epsilon(z) = z^2 -2 -\epsilon$ and $f_{i\epsilon}(z) = z^2 -2 +i\epsilon$ receptively for small $\epsilon>0$. This thesis contains two main Theorems, both dealing with the upper bound for the asymptotic behaviour of $\dim_H(\mathcal{J}_\epsilon)$ and $\dim

As global energy demands rise and the need for sustainable solutions becomes more urgent, so efficient ammonia production is fundamental. Traditional methods, such as the Haber-Bosch process, are both energy-intensive and environmentally harmful. This research investigates an alternative by developing a catalyst for the electrochemical reduction of nitrate to ammonia, using Iron Nitrate Hexahydrat

Given the pressing environmental crisis, marked by climate change, biodiversity loss, and deforestation, precise land cover monitoring has become crucial. In this thesis, we explore the use of privileged information to enhance land cover classification using deep neural networks. Our study specifically focuses on how to best utilise all available data, by leveraging a machine learning framework kn

Mängdlära är den gren av den matematiska logiken där man studerar så kallade \textit{mängder}. I axiomatisk mängdlära undviker man att definiera begreppet \textit{mängd}, men det är meningen att mängder ska bete sig som samlingar av objekt av något slag. Som alltid i matematiken börjar man med att skriva ned en lista med axiom, från vilka man sedan försöker härleda en så rik teori som möjligt. DetWe investigate the strength of the Ultrafilter Lemma in comparison to the Axiom of Choice. In particular, we prove that a number of classical mathematical theorems are equivalent to the Ultrafilter Lemma over $\sf ZF$, and we study a few results which are typically only obtained in $\sf ZFC$ (as opposed to $\sf ZF$) but which can also be proven from the conjunction of $\sf ZF$ with the Ultrafilter

Det finns ingen tydlighet i vad instrumentkännedom i piano innefattar. Vi ser att pianots konstruktion, egenskaper och instrumentkännedom skiljer sig märkbart på akustiska och digitala pianoinstrument. Studiens bakgrund är kopplad till våra egna erfarenheter som pianolärarstudenter och framtida pianolärare. Vårt syfte med studien är att ta reda på vad instrumentkännedom innebär för olika pianoläraThere is no clarity on what instrument knowledge in piano should contain. We can see that the construction, functions and instrument knowledge vary significantly depending on if it is an acoustic or digital piano instruments. The background of the study is based on our own backgrounds and experiences as students and future piano teachers. Our purpose with the study is to learn what instrument know

Primary forests are species-rich, carbon-storing ecosystems that represent natural landscapes without human intervention. In contrast, traditional European forestry practices often involve monoculture plantations aimed at maximizing timber yields, leading to reduced tree life cycles, and affecting the carbon cycle. Despite accounting for less than 3% of forest land in the European Union, primary f

Cross-laminated timber (CLT) is an engineered wood product constructed by combining multiple layers of wood lamellae with adhesives. In the serviceability state, structural timber elements, that are light–weight, are more susceptible to complications regarding the vibration level, than heavier structural elements such as concrete. Contemporary standard practice in the building industry, is to use

Föreliggande studie intresserar sig för hur en lärare kan tillvarata och skapa utrymme för elevers personliga drömmar, mål och visioner med att studera på det estetiska programmet inom ramen för ensembleundervisningen. Vidare undersöker studien hur en lärare, med utgångspunkt i elevernas drömmar, mål och visioner kan skapa förutsättningar för elever att känna motivation. Den tidigare forskning somThis study is interested in how a teacher can make use of and create space for students’ personal dreams, goals and visions by studying the aesthetic program within ensemble teaching. Furthermore, the study investigates how a teacher, based on the students’ dreams, goals and visions can create an environment where students can feel motivated. Previous research on the subject covers students’ desir

I studien undersöks i vilken grad och på vilket sätt läroboksuppgifter i fysik, genom sin utformning, främjar gymnasieelevers begreppsförståelse. Begreppsförståelsen definieras som elevernas förmåga att använda kunskapen i nya sammanhang. Studien betonar lärobokens viktiga roll i att forma elevernas förståelse. Uppgifter som främjar begreppsförståelse bör exempelvis vara varierade och knyta an tilTextbook tasks are a critical part of physics education as they build a wide range of skills necessary for mastering the subject. This study evaluates the nature of tasks in three widely used Swedish high school physics textbooks, focusing on whether they enhance conceptual understanding or are primarily aimed at memorization of facts and procedural use of formulas and physical relationships. The

The ocean’s importance for human survival is indisputable. However, humanity's continuous impact on the ocean negatively affects its well-being. While this interrelation is acknowledged, only a few studies research the relationship between the ocean and societies. Thus, this study aimed to explore whether specific concepts and theories are necessary when analysing ocean-society relationships.

This master's thesis, in collaboration with Comsys AB, examines the optimal size of a Battery Energy Storage System (BESS) for two services - energy shifting and constant power delivery across the four price areas SE1, SE2, SE3, and SE4 in Sweden. For energy shifting applications, the optimal storage capacities were found to be 20 MWh (2 MWh/MW) in SE1, SE2, and SE4. However, a 0.5 MWh/MW stor

Platssamverkan aktualiserar en rad aktuella ämnen, såsom arbete med social hållbarhet, segregation och gentrifiering. Polisens lista över utsatta områden påverkar ett område, och det är något som fastighetsägare måste ta ställning till. Många fastighetsbolag arbetar med platssamverkan men ännu finns inte mycket forskning på vilka effekter frivilliga former av samverkan har och hur fastighetsbolag Place-based collaboration raises various contemporary issues, including efforts towards social sustainability, rising segregation, and gentrification. The Swedish police's identification of vulnerable areas impacts localities, prompting property owners to respond. While many property companies engage in collaboration, research on the effects of voluntary collaboration and the diverse approache

Eftersom innovation ger konkurrensfördelar, ökar marknadsandelar och påskyndar den övergripande institutionella tillväxten, utgör innovation en erkänd framgångsfaktor för organisationer. Under det senaste decenniet har ett paradigmskifte från traditionella innovationsstudier, med fokus på forskning och utveckling, till medarbetardriven innovation (EDI) skett. Då den senaste litteraturkartläggningeInnovation is widely recognized as a critical factor of organizational success as it cultivates competitive edge, augments market share, and accelerates overall institutional growth. During the last decade, a paradigm shift from the traditional innovation studies, focusing on research and development (R&D), toward employee-driven innovation (EDI) has been observed. However, the last literature
