Massan i vår galax Vintergatan, består av en idag stor del okänd massa som kallas mörk materia. Den mörka materian motsvarar ungefär 80\% av den totala massan i vår galax. Att ta reda på naturen till denna mörka materia är idag ett hett forskningsområde i både astrofysik och partikelfysik. Trots årtionden av experiment med mål att hitta dessa partiklar som denna massa består av har vi än idag gåttStellar streams are made of stars that originate from globular clusters or dwarf satellite galaxies that have been disturbed by the gravitational pull from the galaxy they orbit. These stellar streams hold information about the history of the progenitor as well as information about the gravitational potential of the host galaxy. In this thesis we make use of the high resolution cosmological zoom s

Inom matematiken är det ofta viktigt och användbart att "maximizera" en derivata. Det betyder att man hittar en funktion som har den största derivatan i en punkt bland en familj av funktioner. Detta kallas för ett "extremal problem" och vi söker en lösning till detta problemet. Den finska matematikern Lars Ahlfors upptäckte en sådan lösning i 1947. I denna uppsatsen kommer vi uExtremal problems in analysis have been studied for more than a hundred years. The so called Ahlfors function is the solution to one such problem. In this thesis, we shall study several properties of this function in a most general domain. We will consider the Ahlfors function in the context of analytic capacity, and also relate it to Riemann maps of simply connected domains onto the unit disk. Ou

Within recent years, the concept of Humanitarian Innovation (HI) has emerged and received growing attention within the humanitarian system as a critical means of adapting to growing complexities, uncertainties and resource scarcity. While perceived as a means of stimulating broader system changes and increasing effectiveness and efficiency of humanitarian assistance, current efforts of HI have met

Number theory is in a sense among the oldest disciplines of mathematics. A running theme is that many number theoretic problems are very easy to state and understand. However, actually solving these problems often requires much work or some very clever trick. An extreme case of this would be Fermat's last theorem: originally a conjecture by French lawyer Pierre de Fermat whose statement is und

The internet has revolutionised our world. The digital ecosphere is dominated for the most part by technology companies. The surveillance business model of these companies seeks to create predictions and inferences based on persons behaviour which can be used to shape, nudge and manipulate towards certain goals. This presents immense challenges to human rights, especially to the right to privacy.

Nepal has long been recognized as a multi-cultural country with a diverse geographical area. Despite its natural beauty, Nepal is plagued by a number of social issues. Violence against women has always been an issue, exacerbated by patriarchal cultures. Several development organisations are trying to alleviate the situation. The aim of this research is to decide how development organisations integ

Background The importance of services is increasing, and companies need well-developed service contracts to ensure the service providers perform at a satisfying level. In contracts, performance-dependent rewards (incentives) can be used to stimulate the agent to act desirably. This master thesis focuses on E.ON New Solutions B2C, who offers solar panel installations to residential customers. They

Background Transparency of a supply chain is the extent to which all its stakeholders have a shared understanding of, and access to, the product-related information that they request, without loss, noise, delay, and distortion. Having access to accurate and timely information is a challenging issue in global supply chains. Therefore, this research aimed at identifying barriers that could act as

Machine learning as a field has expanded in an explosive manner, with more companies interested in using the technology. One of these companies, Spiideo, uses Machine learning to automatically stream and record sports, highlighting key events - all automatically without a cameraman. However, these cameras have to undergo a lengthy calibration process involving manual feature extraction. This work

Politisk konsumtion är en växande konsumentrörelse där individer konsumerar inte enbart för att maximera egennytta, utan även för att skapa godartad samhällelig förändring, lokalt som globalt. Den teoretiska debatten kring detta fenomen vilar på grunder såsom neoklassisk marknadsekonomi och idén om den suveräna konsumenten. Koncept som har problematiserats och ifrågasatts i relation till denna dis

En viktig sak vi kan göra för att minska avfallets miljöpåverkan är att återvinna. Människorna på denna planet har ett viktigt ansvar, genom att sortera sitt hushållsavfall ökar vi återvinningen. Och genom att göra det kan vi minska utsläppen av växthusgaser, vilket är en stor miljövinst. Därför är det viktigt att människor tar ansvar för sin konsumtion och även sin återvinning av hushållsavfaWhat do people residing in Hässleholm municipality really think about the sorting of their household waste? And do they understand why it`s important to sort their waste? By sorting and recycling our waste, we reduce our environmental impact. And when we do this, greenhouse gas emissions can reduce, which gives us a great environmental benefit. The goal of this study was to analyze the sorting

SVEA Medical Sport AB är återförsäljare av sportartiklar. Företaget saknade klara strategier angående beställningskvantiteter samt beställningspunkter för deras produkter och de misstänkte att de band upp mer kapital än nödvändigt. Företaget hade också problem rörande förståelse för sina restorderkostnader. Syftet med examensarbetet är att kartlägga och klargöra den faktiska orsaken till problemen

Background: The United Nations Sustainable Development Goals (SDGs) were launched in 2015 to be achieved by 2030. Goal 5 aims to achieve gender equality and empower women and girls. This study conducts a feminist analysis of gender equality concepts and data with the aim of finding adequate baseline indicators for measuring SDG 5 progress in Kenya. Methods: A convergent mixed methods research de

This dissertation serves to explain the theory behind three-dimensional scanning x-ray diffraction while at the same time connecting the theory to a software package used for processing data obtained from measurements using scanning x-ray diffraction. This software package is then used and built upon to analyse the data obtained from the measurement of a sample of 12 silica grains subject to an un

Making Europe climate neutral by 2050 is the primary goal of the European Green Deal. This goal has given rise to sustainable finance and action plans for financing sustainable growth. Such commitment is ensured by the legal initiatives put forward by the Commission. The Non-Financial Reporting Directive introduced the requirements for some firms to produce a sustainability report based on disclos

Does it pay to adopt Climate-Smart Practices? Despite the general understanding that CSA practices or innovative land management methods increase farmers’ food security, the key to the current debate within the literature is to understand the extent to which CSA practices explain differences in farmers’ productivity and resilience to climatic shocks. To fill this gap, this study examines the varia

Purpose: The high failure rate of M&As is still one of the main puzzles. The purpose of this research is to identify how concepts of failures changed after the global financial crisis and to see the main causes of such failures according to the research in the set time frame. Theoretical framework: Motives of M&A failure are categorized into synergy motive and self -managerial motives. Ba
