This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. Reference signal is 163.84MHz, reference-spurs is -80dBc/-98dBc lower than main frequency. RMS
Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. Oily yeasts have several advantages in comparison to alternatives; their doubling
Den här rapporten syftar till att studera möjligheten för kommuner att reglera lägenhetsstorlekar i bostadshus. Regleringen kan vara ett medel för kommuner att säkerställa sina intressen utifrån det kommunala bostadsförsörjningsansvaret. Ansvaret innebär att kommuner är skyldiga att planera bostadsförsörjningen i kommunen i syfte att skapa förutsättningar för bostäder till kommuninvånarna. SyftetThis thesis examines the possibilities for municipalities to control the sizes of apartments in residential buildings. Municipalities may want to regulate apartment sizes in order to secure their interests according to their responsibility to provide good prerequisites for dwellings. The purpose of the thesis is to investigate which possible methods that are available and whether it is appropriate
Although the EU has substantial influence over how and with what Swedish municipalities work, the national level still tends to be the point of departure for the EU cooperation and analysis thereof. This qualitative single case study intends to abandon that tradition through investigating the consequences of EU projects at the local administrative level. Due to a lack of earlier research about the
Denna studie har syftat till att undersöka den retoriska potential som hip hoppens lyrik, rap, skulle kunna besitta i klassrumssammanhang. Undersökningen intresserar sig för dess effektivitet som minnesstrategi men också dess potential som ett media att förmedla kunskap. Genom en övergripande analys av begreppen retorik och hip hop synliggörs detta och undersöks därefter genom autoetnografisk aktiThis study has aimed to explore the rhetorical potential that hip hope poetry, rap, could possess in classroom contexts. The study is interested in its effectiveness as a memory strategy, but also its potential as a media to convey knowledge. Through an overall analysis of the concepts of rhetoric and hip hop, this is made visible and then investigated through autoenographic action research. The r
Batterier möjliggör mer solel än elnätet tidigare klarat av En ökad andel solenergi i elnätet ställer nya tuffa krav på det befintliga nätet. I det här examensarbetet har möjligheten att undvika nätförstärkning genom att istället installera batterier på väl valda platser i nätet undersökts. Med hjälp av lösningen kan mer solel än nätet tidigare klarat av installeras. Historiskt sett har el produThis thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. This could enable faster integration of solar power and a reduced demand for
The paper examines the relationship between non-formal education activities and youth employability in the Republic of Armenia. A case study has been conducted in order to identify soft skills competitive in the labour market and see to what extent non-formal education increases youth productivity thus helping them get engaged in the job market. Another thing that the paper aims to study is the ro
Current land use change and habitat fragmentation have caused severe decline in bumble bee populations. In order to address this issue and plan future conservation measures and strategies for plant pollinator networks, it is important to understand their foraging behaviour. A few studies in the past have tried to understand foraging constancy in bumble bees. However, there is no clear information
This study deals with rights for the good care of the elderly in the municipalities of Scania. The study is meant to give deeper knowledge of citizen's charters for care, why such charters have been given and if they can be used to secure the quality of the care of the elderly today and in the future. To put these citizen's charters in a context I have chosen to study how the state after v
Sustainable waste management system which focuses on prevention, reuse and recycle instead of burn and bury is difficult to agree upon, design and implement. I look at why after 8 years of development the city of Sofia chose to burn and bury most of its municipal waste despite a better though more difficult to implement alternative based on the Zero Waste concept was presented. I focused on the dy
An upcoming trend in the current IT-landscape is to outsource services to so called Cloud Service Providers (CSPs). However, many companies are still sceptical to this new kind of services, since they bring about a certain loss of control. For this reason, it is important for CSPs to show that their services are secure. There are several options in proving this and it is up to every CSP to choose
Cinema is an externalised, materialised form of collective memory in which one can find experiences, desires, traumas, ideas, hopes and imaginations of the given society. One can - with the utilisation of the right set of tools and methods - learn a lot about a society by studying its cinema. In this context, this thesis offers a social semiotic analysis of the debut film Otobüs (The Bus, 1974) by
Business intelligence (BI) is all about making decisions. The purpose of many business intelligence tools is to improve these decisions by making data easy to visualize and understand. Qlik Sense is a BI tool developed by the company Qlik which allows users to visualize and explore data by filtering it (called making selections). At the time of this project Qlik Sense did not support visualization
Popular science summary Non steroid anti-inflammatory drugs (NSAIDs) are among the most consumed pharmaceuticals worldwide, and thus belong to the most frequently identified pharmaceuticals in aquatic environments. Until now multiple examinations have shown adverse effects of NSAIDs on life functions of aquatic organisms even in low concentrations. However, there is still lack of data about toxic
Moral and ethical considerations have always been important in discussions about warfare and the development of the international community and body of international humanitarian law, laws whose fundamental ethics that can be attributed to Just War Theory. With the changing nature of conflicts and due to the lack of internationally declared principles of just and unjust wars, this thesis argues th
Det blir allt vanligare att företag producerar separata CSR- och hållbarhetsrapporter. Men tidigare studier av denna kommunikationskanal har lagt fokus på innehållet och inte på hur rapporterna påverkar bilden av företagets hållbarhet. Syftet med denna studie är därför att studera hur en organisation kommunicerar i sin hållbarhetsrapport för att framställa sig själv som ett hållbart företag och föIt is becoming increasingly common for companies to produce separate CSR and sustainability reports. Previous studies of this communication channel has focused on the content and not on how the reports affect the perception of the company's sustainability. The purpose of this study is to examine how an organization communicates in its sustainability report in order to depiction itself as a sus
