This paper addresses the antenna subset selection in multiple antenna systems with full diversity transmission, for both correlated and uncorrelated channels. To reduce the severe performance degradation of traditional selection/combining schemes, we propose to embed phase-shift-only operations in the RF chains before selection. The resulting system shows a significant advantage in utilizing the m
Popular Abstract in Swedish Brosk bekläder våra leder och förser dem med en slät yta vilket förhindrar en direkt ben mot ben kontakt. Det fungerar också som stötdämpare i belastade leder och ger glidytan mycket låg friktion. Vatten hålls kvar i broskets matrix på grund av den negativt laddade proteogykanen Aggrecan vilken i sin tur hålls kvar i ett nätverk av kollagenfibrer. När en led belastas pr
An increased use of the Internet has created new business opportunities. The development of e-commerce has, however, been crippled by a limited understanding of logistics and customer needs. This paper sets out to highlight those issues in pharmaceutical retail where added services should be created through e-commerce. The research is based upon a case study covering the pharmaceutical system in S
This paper introduces a conceptual framework: the CPS triangle, which has evolved over four years of research on ‘older people meet robots’. It is a synthesis of domestication theory, modern social practice theory and empirical data. Case studies on the domestication of one current technology, the robotic vacuum cleaner, and two emergent technologies, the eHealth system and the service robot, prov
Popular Abstract in English Zirconium alloys are widely used in nuclear power reactors as cladding material for their fuels due to the high strength, good corrosion resistance and low neutron absorption cross-section, even in extreme environment, that is characteristic for zirconium. The element, however, also has strong affinity for hydrogen, and when both are present they readily react and form
An increasingly competitive environment, technological advancements and globalisation are a few of the factors placing higher demands on today’s company activities, e.g. development, production and distribution processes. Company activities have hereby become a complex system, even more so if one company is seen as part of a network of companies. The aim of this article is to present and elaborate
Context. Transmission spectroscopy is one of the most powerful techniques used to characterize transiting exoplanets, since it allows for the abundance of the atomic and molecular species in the planetary atmosphere to be measured. However, stellar lines may bias the determination of such abundances if their center-To-limb variations (CLVs) are not properly accounted for. Aims. This paper aims to
The sometimes rapid development of (new) threats and extraordinary events calls for a robust, flexible, and well-equipped civil crisis preparedness system to respond and limit the damage of crisis events. To achieve this, Swedish municipalities and regions are required by law to regularly perform and report risk and vulnerability analysis ‘bottom up’ to governmental agencies. When performed in lar
This thesis examines the theory of headwinds by Robert J Gordon related to Sweden’s economic growth since the 1970s. The specific questions asked are how the two headwinds of income inequality and educational attainment in the USA can be related to a Swedish context. Gordon’s theory is part of a debate on secular stagnation. This thesis aims to broaden that debate by applying one theory of secular
Efter en lång period där många bränder härjade i Sveriges storstäder förbjöds höga trähus. Denna lag upphörde att gälla i mitten på 90-talet och sedan dess har intresset för höga trähus ökat. Detta har resulterat i att behovet av bra ljudisoleringslösningar har blivit större. På grund av det växande intresset för miljöfrågor har det blivit viktigare för företag att hitta nya lösningar för att taIn the last years, the interest in high-rise timber framed building has gone up resulting in an increased demand for good solutions regarding sound insulation. Due to the worldwide growing interest in environmental issues, it has become of greater importance for companies to find ways to take care of their residue, instead of throwing it away. This can benefit both the environment, as less new mat
In regard to the energy sector, it is generally presumed that in post-Lisbon era and since the adoption of Third Energy Package the Member States and institutions of the Union act in a shared format. However, by developing new legislation in the field, supra-national institutions tend to shift the competence away from shared (as it currently stands). Even if the guidelines for decisions granting e
This study attempts to develop Michel Foucault’s analysis of political power in terms of power in ordinary and non-typical political fields, with main focus on the field of food: such as the constructed normalisation of meat in Sweden. The main reason with the analysis is to broaden classical concepts of power within the field of political science in general. Analysis centre around the potential p
Digitaliseringen i samhället breder ut sig i allt större omfattning. Utvecklingen öppnar upp för en mängd möjligheter men kommer även med en hel del utmaningar. Processer som tidigare varit beroende av manuella förfarande kan nu hanteras helt automatiskt. Detta gäller exempelvis möjligheten att fatta automatiserade beslut inom den offentliga förvaltningen. AI möjliggör för mer komplicerade uppgiftDigitalization in our society is rapidly extending into new areas. The development opens up for many possibilities but also brings a number of challenges. Processes that were earlier dependent on manual procedures can now be managed automatically. This can for example be carried out through automated decision-making within the public administration. For more complicated tasks AI can extend the pos
The purpose of this essay is to investigate the effects of the 2015 migration crisis on Sweden’s economic growth and GDP per capita levels, along with the general effects of migration on economic growth in Sweden and the world. Further the possible effects of an employment rate of the migrant labor force equal to that of the native labor force is investigated, and the effect this would have on eco
Systemic Lupus Erythematosus (SLE) is an autoimmune disease where the immune system is attacking the body and its tissues. This leads to a chronic inflammation that can affect different parts of the body and therefore present itself in a vast variety of symptoms. Depending on the activity of the disease it can go up in flares where the patients experience symptoms and then go down into recession.
This master thesis contains an overview of existing additive manufacturing methods and considers possible new methods. The purpose being to develop a method for additive manufacturing that can create 3D objects with composite material and/or out of metal. Further this method should work on a low cost additive manufacturing machine. A development process is used in order to select an appropriate me
This work investigates the significance of the sentence-final particle 'ka' in modern Japanese by means of questionnaire and qualitative discussions with native informants. The Japanese language makes use of short words known as particles to indicate grammatical category. 'ka' is one such particle that can be used to indicate, among other things, the interrogative mood. Questions c
Syftet med studien var att undersöka samband mellan interpersonella anknytningsmönster och högkänslighet. Hypotesen var att Ängslig-ambivalent anknutna individer skulle uppvisa en högre grad av högkänslighet, än de individer som var tryggt anknutna. Studien utfördes på 120 studenter vid Lunds Universitet genom två självskattningsformulär: Highly Sensitive Person Scale (HSPS) och Attachment Style QThe purpose of the study was to examine the relationship between interpersonal attachment in adults and Sensory Processing Sensitivity, SPS. It was hypothesized that individuals with an Anxious-ambivalent attachment would exhibit a higher degree of SPS than individuals with Secure attachment. The study was conducted by recruiting 120 students from Lund University to fill out two self-report-questi
Democratization is one of the most studied and problematic areas in political science. Democracy theories are gaining more power and influence in society and researchers are gaining greater influence over those who work practically with development and democratization. This paper will investigate why Ethiopia is not becoming more democratic, despite the fact that the country has moved from a milit
