Cryptocurrencies are growing at a rapid pace. It is well established that the mining operation fueling the cryptocurrency Bitcoin consumes a significant amount of energy. This study aims to determine if there is an alternative to the consensus model, maintaining security, integrity, and decentralization. It includes a deep dive into the Bitcoin network and the consensus model Proof of Work (PoW ).

The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise. A typical signal is generated from a digital radar and the frequency components stem from point scatters

Purpose: To explore how different B2B companies within the plastic industry are adapting and managing their brand under siege in regards to the environmental pressure from stakeholders. Methodology: This study takes a qualitative research approach, combining primary and secondary data. To create an understanding of the plastic industry, three B2B companies were interviewed in order to investigate

I detta projekt utvecklades ett formspråk för militära sensorprodukter. Med särskild vikt på att företagets olika produkter skulle få ett gemensamt vi- suellt uttryck. Detta formspråk tillämpades sedan på styrenheten till en kamera, vilken används utomhus i tuffa förhållanden. Till styrenheten ut- vecklades en lösning för ett kompakt portabelt lagringsmedia som samtidigt går att använda med tjocka

Architecture can be described as the built variant of culture, and the architecture of the dwelling is particularly affected by norms and assumptions that regulate the way we live and whom we live with. Only 0.05% of dwellings in Sweden are built for collective households and it is therefore worth investigating how they are are affected by a built environment that is not built in consideration of

The efficiency of gold complexes featuring di- or tri-pyridine scaffolds in inhibiting human aquaporins have been previously investigated. They have returned promising results in cancer treatment and have been suggested to be potentially applied against malaria too. ([Au(bipy) Cl_2]+)., ([Au(phen)Cl_2]+) and ([Au(terpy)Cl]2+) in all their possible forms in solution, were computationally studied us

This paper explores how electrical appliances, together with the idea of attaining energy access in the near future, create hope in a northern village in Malawi. Even though less than one per cent of the rural population has energy access, some of these locals already own solar systems. Nevertheless, their solar equipment is not powerful enough to generate the large amounts of energy required to r

We need places in the city where we can just be, slow down and have experiences that are sensual and bodily. When communal baths were built in the cities of Sweden, it was largely for hygienic reasons, a place where people washed weekly. Now you could say that bathing is a kind of ritual, something that we do for the sake of the experience. I designed the bathhouse on an infill plot in Gamla Väste

Background: Secure base scripts (SBS) comprise implicit procedural expectations about the availability of significant others, and are formed early in life based on experiences with caregivers. SBS are conventionally captured via word-prompted, impersonal narratives, but as this assessment paradigm is relatively new, little is known about how it may be affected by situational mental health problems

In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonom

My thesis is about how to design rooms that meet the human need to slow down, contemplate and find peace in an urban environment. Contemplative and quiet rooms with a public character exist as a natural part of common social functions and building types, such as parks, museums, libraries and church rooms. What I want to explore in this work is a type of building that serves as a complement to thes

This thesis examines social practices of valuation. That is, how things and beings are assigned different kinds of worth, and how these valuations are justified. By investigating the case of Danish climate politics and policy discussions the aim of this thesis is to give a first approximation of how nature is assigned different forms of value, foremost among these a monetary price. The theoretical

Denna uppsats syftar till att utforska jubelåret sådant det beskrivs i Lev 25:8–23. Detta görs genom att se på utombibliska traditioner som kan ha influerat lagstiftningen, samhälleliga faktorer som förutsätts av författarna samt lagens funktion i samband med Leviticus slutredigering i tidig persisk tid. Frågan ställs även huruvida jubelåret kan ha praktiserats i verkligheten. Uppsatsen använder s

Bakgrund: Naturbaserad rehabilitering används i Sverige främst för patienter med stressrelaterad ohälsa men har potential till användning för andra patientgrupper. Naturen har hälsofrämjande effekter och får exempelvis människor att lättare slappna av. Arbetsterapeuter arbetar med aktiviteter som främjar hälsa och naturbaserad rehabilitering är ett exempel på en intervention som används Syftet: UnBackground: Nature-based rehabilitation is used in Sweden primarily for patients with stress-related illness but has the potential to be used for other patient’s groups as well. Nature has health-promoting effects and makes it easier for people to relax, for example. Occupational therapists work with occupations that promote health and one example of an intervention is nature-based rehabilitation.

By applying one of the largest datasets on ESG ratings to date with around 8000 companies included during the sample period between 2006-2021. This paper investigates the increasingly popular link between firms’ social and financial performance and the potential abnormal returns to be found using ESG investment strategies. To examine this relationship, a series of portfolios are constructed based

This master thesis project has been done within the Mechanics department of Lunds Tekniska Högskola (LTH). It studies the nanometric cutting process of a single crystal copper workpiece by a cubic diamond tool using Molecular Dynamics (MD) simulations on the software LAMMPS. Several simulations are computed in order to study the influence of different factors. In a first place, several tool model

Nominal rigidity is a central question in the debates to address better models to predict the outcome of certain policies. However, there is little empirical evidence that gives a deeper understanding of the mechanism that transmits this friction into the economy. This paper aims to understand the relationship between price rigidity and wage rigidity in the Swedish economy. I found a positive rela

This text is an attempt to re-evaluate the significance of Roman imports in Scandinavian contexts as well as to answer overarching questions concerning frontier zones, and the building of core-periphery relationships. This is achieved by applying the Roman concepts of hospitium and dona militaria as well as theoretical frameworks such as provincial ritual practices and cultural hybridisation to a

Many theorists have argued that vision and geometry have been given too much precedence within architecture and architectural representation. This thesis uses feminist theory that criticizes the way that space and the future traditionally have been represented. It discusses how the tools that architects use to describe space and future, can affect the how they think. The starting point for the dis
