To decrease the dependency of fossil-based raw materials in society, and with that, the chemical industry, new and sustainable raw materials need to be investigated. Lignin is an abundant aromatic biopolymer, that can be used to produce, e.g. aromatic fine chemicals through depolymerization. In this master’s thesis, different homogeneous and heterogeneous catalysts were screened for oxidative depo
The study investigates how small and medium-sized enterprises (SMEs) entrepreneurial marketing activities on social media instigate cognitive, emotional and behavioural aspects of customer engagement. Using a qualitative research design and conducting semi-structured interviews, the study explores how these marketing strategies instigate different types of consumer behaviours and engagement levels
Manufacturing companies increasingly adopt the strategy of adding services to their product offerings to differentiate themselves and overcome product commoditization. The bundling of products and services in complex product-service systems has the potential of high value creation and superior customer experiences. However, this shift requires business model innovation and acquisition of capabilit
The Klein--Gordon equation is a relativistic wave equation which models a relativistic spin-free particle. In this thesis we investigate the asymptotic behaviour of the linear Klein-Gordon equation with a rapidly decaying potential in one space dimension. This is done by first studying the case with zero potential and finding asymptotic estimates using the method of stationary phase. This is a met
Title: The Role of Concept Stores: Consumer Perceptions of the Intended Brand Image Seminar date: 2024-05-30 Course: BUSN39, Degree Project in Global Marketing, Business Administration: Master Level Authors: Petra Ohlson & Emma Stenkil Supervisor: Ulf Johansson Research question: Why are fashion manufacturing brands opening concept stores? How does consumers' perception of the concept stor
Klorparaffiner är ämnen bestående av klorerade kolvätekedjor och kan indelas i tre grupper: korta, mellan och långa ämnesgrupper. Denna rapport syftar till att sammanställa tillgänglig kunskap om klorparaffiner i helhet med inriktning på föroreningens förekomst och dess implikation på grundvatten. Samtliga ämnesgrupper har använts flitigt sedan 1930-talet inom metallbearbetning och plasttillverkni
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
Let $\dim_H(\mathcal{J}_\epsilon)$ 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
We 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
