Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m

Models of physical systems are often expressed as a system of mathematical expressions derived from first principles. However some of the relationships present in a model are more conveniently expressed as a table, i.e. for certain values of independent variables the values of dependent variables are known. This imposes a limitation on the optimization software to be used, since optimization softw

Problemställning: Ändringar i EU:s lagstiftning har på senare tid förändrat mervärdesmatsbranschen genom att skärpa kraven för påståenden till konsumenter. Samtidigt har mervärdesprodukter växer för husdjur ökat. Att på ett korrekt sätt följa den nya lagstiftningen kräver en ny typ av kunskap inom mervärdesbranscherna, vilket blir ännu tydligare för produkter med innovative påståenden som inte är Background: Recent changes in EU legislation have changed the industry of functional foods by tightening substantiation requirements for claims made to consumers. Parallelly, functional products are growing within the pet food segment. To follow the new legislation requires a new kind of knowledge within both industries, which becomes even more apparent when developing innovative products with les

Denna studie ämnar att öka förståelsen för hur marknadskommunikation kan utgöra ett medel i diskursiva maktkamper på en konkurrenskraftig marknad samt hur denna kommunikation kan tänkas tolkas och förstås av mottagaren. Studien utgår från fallet LRF och Oatly där vi undersöker den diskursiva maktkamp som uppstått mellan deras skilda sanningar om mjölk och hur de förhåller sig till varandras sanninThis study aims to increase the understanding of marketing communication as a tool in a discoursive power struggle on a highly competitive market and how communication might be interpreted and understood by the reciever of the message. The study is based on the case of LRF and Oatly where we examine the discoursive power struggle, which arose from their different truths about milk, and how the ope

A growing world population confronts humanity and the planet with several challenges due to its increased demand for food, space and energy, implying changes in land use. While agriculture currently provides enough food, it is destroying biodiversity and hence aggravates the planet ́s vulnerability to climate change. A paradigm shift might therefore be needed. Applying a political ecology lens, co

Den offentliga förvaltningen spelar en central roll för det svenska samhället och för demokratins bevarande, vilket ställer höga krav på de som arbetar inom förvaltningens alla nivåer som offentliga tjänstemän. En stor del av de offentliga tjänstemännen kan identifieras som så kallade närbyråkrater, vilka kännetecknas av att de har en nära kontakt med medborgarna och utgör således en viktig del av

Både Norges och Sveriges regeringar har skapat sametingen i syfte att inkludera samerna i rikspolitiken. Det är dock oklart hur mycket sametingen kan påverka den faktiska politiken. I den här studien utgår vi ifrån teorier om intresseorganisationers möjlighet till inflytande och applicerar dessa på sametinget. Genom en fallstudie av processen bakom ländernas minerallagstiftning har vi studerat någ

Denna uppsats argumenterar för att organisationer och arbetsliv sedan 1950-talet präglats av en dikomisering mellan två perspektiv: kognitivism och konstruktivism. Ingetdera av dessa når enligt uppsatsen upp till förväntningarna om en hållbar teori och praktik. Kognitivismen har ett fundament av alltför naiva sanningsanspråk, vilket gör att den kollapsar in i en paradox. Konstruktivismen å andra s

Simulation studies are today an important tool in the development of new networks. For this purpose the NS-3 network simulator can be used. The focus of this thesis work lies on 802.11ac, the latest version of the Wi-Fi standard. NS-3 does not support the IEEE 802.11ac standard and the goal was to implement features for this. Different deployment scenarios were modeled in various conditions and th

This thesis aims to investigate how the parties represented in the Swedish parliament justify the ban for Swedish citizens to wage war for any army except the Swedish. The analyzed material has been collected through personal interviews with each party’s legislative spokesmen. The method used to analyze the material is an analysis of ideas inspired by Torbjörn Aronson’s morphological content analy

The use of detention centers for refugees in Sweden has been criticized over the last couple of years. The lack of resources and the shortage of accommodations have resulted in the use of alternative facilities such as police detentions and prisons. These alternative facilities has since 1994 been criticized by the European Committee for the Prevention of Torture. But still the alternative detenti

This thesis concerns the impact of instrumental benefits and norms on state behaviour in international relations. This is studied on the case of the EU’s and Japan’s initiation of enforcement against North Korea in the UN Human Rights Council, which has garnered increased attention since 2013 when a commission of inquiry successfully put the issue on the international community’s agenda. I ask w

The collective housing movement in Sweden has undergone a lot of changes since it started in the 1930s. It has identified different problems over the years, but the solution has always remained the same. In my thesis I ask if these changes can be explained with individualization-theories, and my hypothesis is that the movement has been individualized. I have chosen to analyze the collective housin

Syftet med undersökningen har varit att utröna hur existensen av deflation påverkat aktiemarknaden. Den data som låg till grund för den ekonomiska analysen var främst finansiell data, men också makroekonomisk data, från Japan mellan 1969 och 2015. Data från USA i samma period förekom också. Den ekonomiska analysen gjordes genom att testa samband med OLS- och binärvalsmodeller. Inflation, och som

Social workers today have the whole world as their work field and the global social work is often carried out in international non-governmental organizations (NGOs). To work internationally and in NGO's have according to previous research shown to be complex. Therefore the aim of this study was to examine international professionals and their views on their role and function working in NGO´s s
