Med moderna mikroprocessorer kan motorstyrning göras i mjukvara. Ett mer konkret exempel är möjligheten att köra tvåfasstegmotorer med strömreglering. Redan med en enkel regulator kan mycket bra resultat uppnås. Stegmotor är en elektrisk motor som har fått sitt namn för att ett varv är uppdelat i ett antal lika stora steg. Antal steg/varv varierar och väljs utifrån motorns användningsområde. En s

When critical scholars coming from different academic disciplines, such as sociology, gender studies, or Black studies, meet and discuss today, discussions sometimes take the form of whether recognition of particular identities or redistribution of material resources is of most importance. In this thesis, my aim is to explore resources that could contribute to moving beyond this framing of the que

Merger control in Sweden and the EU has done a prominent job in adapting to the special competitive aspects of digital platforms. Merger investigations by the Swedish Competition Authority and the European Commission include an assessment of the significant impediment to effective competition (SIEC test). The test is described in article 4(1) of the Swedish Competition Act and articles 2(2) and 2(

The thesis paper intends to perform a relevant study on the closed-end fund puzzle in the perspective of an emerging market. Quarterly data of 36 closed-end mutual funds traded in Dhaka Stock Exchange are collected over the sample period of 2016 to 2019. Dependent and Independent variables are mapped down by exploring previous research. Number of stocks, weight of top 10 investments, fund size, fu

Denna avhandling beskriver studier av hur metallkomplex som fungerar som katalysatorer i lösning kan absorberas i s k metall-organiska nätverksstrukturer (metal-organic frameworks = MOFs). MOFs är porösa kristallina material som har en bred funktion i såväl laboratorium som industri. Genom sådan absorption kan det lösliga komplexet inkorporeras i håligheter i nätverket; det lösliga komplexet befinThis work constitutes the results from a one year master thesis research project (Sep, 2019 to Aug, 2020). Metal-Organic Frameworks (MOFs) have been used for encapsulation of homogeneous catalysts to generate heterogeneous catalysts. This work describes the incorporation of the non-heme iron complex [(Fe(II)N4Py)]2+ and two molybdenum−sulfur clusters (MOS) into the pores of UiO-type MOFs via absor

Olösliga problem blir lösbara med framtidens kvantdatorer! Under 1900-talet gjordes oerhörda framsteg i vår förståelse av kvantmekaniska fenomen, men för varje besvarad fråga väcks två nya. Många högaktuella frågor, och mål, gäller förverkligandet av kvantdatorn, där en av de främsta frågorna är: vilka kvantmekaniska fenomen ska utgöra grunden för kvantdatorns grundkomponent (en ’qubit’)? AlternatIn this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. The contact quality assessment is based on parameters extracted via electrical characterization performed mK temperatures in

Like many things, social movements have been able to take a new form, and behave differently, thanks to the rise of the internet and social media networks. The purpose of this study is to analyze how long lasting this engagement is from its participants, and how short-run participation in social movements can be understood. This study has been heavily inspired by Zizi Papacharissi, therefore the t

De senaste decenniernas juridiska utveckling där nya sorters entiteter erkänns status som rättssubjekt har aktualiserat frågan om vad som egentligen definierar ett rättssubjekt och vad rättssubjektivitet, de rättsliga positioner som rättssubjekt typiskt sett kan inneha, egentligen innebär. Uppsatsen använder sig av en av de senaste teorierna i ämnet, Visa Kurkis the bundle theory of legal personThe past decades new kinds of entities have been recognised as legal persons. This global development in law have led to an increased academic interest in the concepts of legal person and legal personhood and what it is that defines these concepts. The thesis explores legal personhood through one of the latest theories on the subject, the bundle theory of legal personhood of Visa Kurki. It does

The aim of the study is to examine how young women conceive their empowerment processes through access to ICTs, provided by the non-governmental organization IT for Children. The thesis is a qualitative case study of young women’s empowerment. Accordingly, a minor field study was conducted in the village Dixcove in the south of the western region of Ghana. Material was gathered through semi-struct

The SDGs provide a global policy framework for regulatory actions at national, regional and international levels. However, when it comes to how to locally implement these goals it is important to understand the context of the local reality. This paper has two objectives. It seeks to critically analyse how the Sustainable Development Goals (SDG) goals are framed by civil society organizations (CSO

Humanitarian crises caused by natural disasters or human reasons have hampered the access of generations of young adults to higher education. The aftermath of the Syrian conflict in 2011 led to the emergence of various initiatives, mostly set in neighboring countries and the global north, for refugees and displaced populations to pursue higher education studies. Policymakers and academics have foc

Narrative and gender are both notions closely connected to culture and society. Narrative, on the one hand, is not just the art of telling stories, it carries deeper meanings, evokes feelings, and even affects our actions and interactions with one another. Gender, on the other hand, and specifically social gender, is defined as the gender identity that a person has shaped through his or her intera

As the clock ticks on our opportunity to limit catastrophic climate change, mitigation efforts are becoming increasingly essential, especially amongst countries with high current or historic emissions. However, these mitigation attempts are not a guaranteed success, especially when the system within which they operate is not understood due to unacknowledged bias in quantitative data. As such, wick

Purpose: The purpose of this study is trying to understand which elements are essential to obtain loyalty in the alcoholic beverage industry and how companies can focus their branding efforts on these drivers of loyalty. Methodology: A literature review is conducted to identify the key drivers which can influence brand loyalty. These drivers are then analysed by researching two case studies, Hein

This thesis analyzed multimodal social media communications of a government agency that manages national parks, to study the kinds of discourses that are constructed by national parks agencies through representations of the parks and their nature. Furthermore, it analyzed and interpreted how the discourses relate to the mandate and other missions that the agency must adhere to, which are generally

Sound ranging is a method to locate sources of sound waves using microphones or other types of receivers at known reference positions. Nowadays, these receivers can be made both very small and powerful, lasting for a long time on a single battery charge, making them suitable for longtime outdoor purposes such as detecting artillery fire or other loud sounds. In this master thesis, we present a sou

The Viking Age saw the colonisation of most of the isles of Scotland by settlers from Norway. These newcomers brought their own customs, practices and perceptions to the Isles, maintaining close links with the Scandinavian world. However, these islands had already experienced millennia of anthropogenic change by the time of Norse settlement, and generations of previous inhabitants had populated th

Planning for capacity in not just the production, but also in the supply chain, is important. Strategic long-term planning for the supply chain will affect how the company will be able to meet the demand. This Master Thesis will focus on the capacities within the supply chain at PolyPeptide and how they could be planned for in the future. PolyPeptide is a company that manufactures active pharmaceu

This paper investigates if migration policy reforms have the ability to affect the trade enhancing effect of migration. Migration policies are one of the factors through which a country can control its migration. A shift in migration policy could therefore possibly alter or affect the effect that migration has on trade. In order to investigate this, the Swedish asylum policy changes of 2016 and it
