This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. for banded Toeplitz matrices. The approach is geometric
The purpose of our study is to gain a better understanding of the influence of remote working on employees’ sense of belonging. A specific interest is shown in the variety of work relationships: those who are normally collocated and those who are normally remote.
Skadelindringshierarkin är en vanligt föreslagen princip för att minska påverkan på naturkapital inom planprocesser. Skadelindringshierarkin innebär att påverkan på naturliga miljöer i första hand ska undvikas, annars minimeras – och när detta inte är möjligt återställas inom området eller kompenseras enligt en ekvivalens- och närhetsprincip. Beräkningarna kan utföras i en modell som exempelvis GrA commonly proposed principle for reducing impact on natural capital within the planning process is the mitigation hierarchy. The mitigation hierarchy means that impacts should primarily be avoided, otherwise minimized, and when this is not possible - restored or compensated according to an equivalency- and proximity principle. The outcome can be calculated in a model such as the Green Space Facto
This master’s thesis explores the objectives of packaging regulations and translates them into guidelines for a company’s packaging decision-making process. The thesis was done in collaboration with Axis Communications AB, where the current packaging practices were analyzed. This was followed by analyzing the requirements of packaging regulations in the EU (such as PPWD and upcoming PPWR) and othe
Denna masteruppsats undersökte potentialen i att använda biobaserade akrylatmonomerer för att producera mer hållbara vattenbaserade golvlacker jämfört med de petroleumbaserade monomerer som nuvarande används. Dispersioner skapades genom emulsionspolymerisation och formulerades med koalecenter och vätningsmedel för att bilda lacker vid rumstemperatur. Den främsta utmaningen med biobaserade monoThis master thesis investigates the potential of using biobased acrylic monomers to produce more sustainable waterborne floor coatings compared to the petroleum-based monomers currently in use. Dispersions were created through emulsion polymerization and formulated with coalescent and a wetting agent to form films at room temperature. The primary challenge with biobased monomers is their highe
There are many factors that are involved in fostering intrapreneurship in a company and knowledge management is one important process in achieving that. A previous study related to intrapreneurs’ knowledge management has proposed a framework that discusses knowledge management in various situations, focusing on exploitation, exploration, or in between, in the context of intrapreneurship. Building
Transylvania’s countryside, characterized by a mostly agrarian society with a rich multicultural heritage is being threatened by Romania’s tendencies of chaotic modernization and rapid urbanization. This research aims to find a viable solution for sustaining the cultural, natural, and social environment in rural Transylvania, by analysing the potential of tourism development. Integrated Rural Tour
Architecture greatly influences people‘s lives regarding health, stability, and education and is crucial for economic and social development. This architectural thesis project aims to improve the living conditions of a marginalized community in a rural Tanzanian village, Kisarawe, through a design proposal. It analyzes the potential of humanitarian architecture from the international, European, an
En stor del inom utvecklingen av nya produkter är test och validering. Denna process kräver användning av dyra och stora testsystem. På grund av dessa faktorer är det viktigt att maximera användningen av dessa testsystem. Till följd av detta har ett övervakningssystem utvecklats av test- och validerings-avdelningen på BorgWarner i Landskrona som kan läsa driftstatus (Till exempel på och av) av visA large part of developing products is the testing and validation of the new products. This process requires expensive test systems and a great deal of time and space. Because of these factors it is very important to maximize the usage of the test systems. Therefore, a monitoring system has been developed by the test and validation department at BorgWarner Landskrona that can read the operational
This research investigates the subject of Data Democratization (DD), the effect it has on fact-based decision-making, and how users perceive this within the organization. DD is a fairly new initiative, empowering more employees with increased access to data to improve their use of it and to a greater extent be able to make decisions based on data. The idea for this paper originated from the lack o
The aim of this empirical study was to find out which characteristics, behaviors, and drives high-performing women have in common in order to illuminate why they have become successful in their work. The aim also included getting insights into some of the challenges that these women meet. Participants were fifteen high-performing women who work in business and academia in Sweden. Semi-structured,
The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. This to investigate the content of the fuel-containing capsules, primarily to ensure non-proliferation of radioactive materials in the nuclear waste
Cancer is a widespread and commonly fatal disease in constant need of new treatments. Traditionally, new pharmaceuticals have been tested in 2D models. This is not ideal, as 2D environments do not reflect the in vivo milieu of the cells. Instead, it has been increasingly suggested to implement 3D models, which are thought to be more predictive of in vivo responses to treatment. It has been shown t
Background: environmental impact from health care contribute to a substantial part of the public sector’s consumption based emission of greenhouse gases in Sweden. An issue, recognized by the health care sector itself, is the increasing use of single-use products. Objective: to compare environmental impact and cost differences between a single-use, ResposableTM, and mixed setup of the surgical in
Growing amounts of waste generation in remote areas without proper waste management systems is a problem to human health and the environment. The Amazon holds the biggest freshwater resources in the world, is a biodiversity hotspot and its communities are placed in distances that can take days by boat to be reached. A National policy with EPR instruments requires private companies to take-back pac
Since the 1970’s there has been several attempts within the UN at drafting a binding instrument on business and human rights. Up until today, none of the attempts at adopting binding standards have succeeded, with the only successful initiative being the United Nations Guiding Principles on Business and Human Rights – a voluntary set of guiding principles meant to further the respect for human rig
Flooding is a major risk to the ever increasing urban population, posing a threat to human lives but also causing traffic interruptions, economic losses and pollution. Built up areas are prone to flooding due to the changes of previously pervious surfaces being covered by buildings and impervious pavements, such as asphalt. Furthermore, the resulting increased surface runoff does often not get rou
Over the last decades, Sino-African diplomatic relations have undergone various changes, corresponding with China’s strategic objectives in and with the respective countries. Under the Xi administration, China’s approach to diplomacy has focussed on the quest of becoming a major global power while, or rather through, upholding its traditional values. This paper seeks to analyse how the current dis
This study analyzes the influence techniques applied when hijacking an organizational crisis in order to construct a larger narrative about Sweden. By applying the concepts of narration, mythical speech and moral culture, the study investigates which narrative techniques are applied to generate engagement in disinformation narratives. This was done through conducting a qualitative content analysis
