The decay of solutions to the Klein-Gordon equation is studied in two expanding cosmological spacetimes, namely (1) the de Sitter universe in flat Friedmann-Lemaitre-Robertson-Walker (FLRW) form, and (2) the cosmological region of the Reissner-Nordström-de Sitter (RNdS) model. Using energy methods, for initial data with finite higher order energies, bounds on the decay rates of the solution are ob
Syftet med studien är att undersöka hur kontrollmodellen har tolkats och tillämpats i praktiken inom fastighetsbranschen, utifrån de teoretiska perspektiven kring principbaserade standarder. Vidare ämnar studien analysera huruvida utfallet har bidragit till en mer jämförbar och konsekvent intäktsredovisning. Den forskningsstrategi som använts i denna studie är av kvalitativ karaktär.

Stickiness between materials can be a challening task when dealing with the complex interactions and processes related to packaging engineering. Part of the problem is that many factors like temperature, pressure, surface treatment as well as surface roughness all could play a part in contributing to the stickiness between materials. In this thesis a literature study has been done to map out poten
OPCPA stands for optical parametric chirped-pulse amplification. It is a nonlinear method for amplifying broadband laser beams. The spatial properties of the output of the laser beam depends on the amplification method itself and the broadband configuration. The phase matching in this method causes the different wavelengths in the broadband to have different angular dispersions. In order to inves
We are constantly interacting with UI/UX in different shapes, forms or applications, which is very important especially when using electronic interfaces. Therefore, we need to design well-thought-out and user-friendly interfaces that elevate the user’s experience. When it comes to fantasy sports games, statistics is a big factor for understanding fantasy sport which might be at most times overwhel
“Choice blindness” (CB) refers to a certain tendency to accept a choice that is presented to us as if it were our own, even when we have never made it. In the last decade, CB has been treated as a research tool in a series of experiments in different domains and modalities (e.g. Johansson et al. 2005, 2008; Hall et al. 2010, 2013; Sagana et. al 2014; Cochran et al. 2016) in order to study the rela
As the global world population is growing, so is the demand and consumption for the earth's natural resources. Circular economy has attracted global attention as an alternative to the predominating linear economic system. The construction industry represents a field causing significant climate-and environmental impact and waste. How circular economy should be applied practically within constru
The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame. A principle design wil
Syftet med denna uppsats är att redogöra för hur ekonomin påverkas av legalisering av cannabis för rekreationsbruk. Ekonomin är en mycket intressant och meningsfull aspekt av legaliseringen där resultat inom olika områden används för att utvärdera eftereffekter och finna positiva och negativa trender för att se om resultaten är önskvärda eller inte. Genom detta arbete samlas tidigare studier och d
Background: The current lack of knowledge among entrepreneurs to manage the e-commerce market has created an increased need for incubator activities and the support that incubators can assist entrepreneurs with. Incubators intend to contribute with support for companies by assisting with various services where the success of business development can lie in different combinations of these services
Bakgrund: Alkoholrelaterad ohälsa är ett folkhälsoproblem som leder till lidande på individ och samhällsnivå. Distriktssköterskan ska arbeta hälsofrämjande och personcentrerat. Tidigare forskning visar att sjuksköterskor upplevde okunskap och rädsla att möta dessa personer. Syfte: Syftet med studien var att belysa distriktssköterskans upplevelser av utmaningar och användning av verktyg i bemötande
Linear time-invariant systems are ordinary differential equation systems that arise in control engineering where they are used to model e.g. signal processing, chemical processing and economics. A study is conducted on linear time-invariant systems, their solution and three key properties they have: Observability, reachability and stability. Three algorithms, Gaussian elimination, singular value d
This thesis draws on eleven semi-structured interviews with Duterte supporters. It analyses how the president is perceived by Filipinos, more specifically by those who support him and live in Sweden and the Philippines, in order to provide an in-depth understanding of the appeal of Duterte to his supporters. The thesis focuses on the main reasons for Duterte’s popularity, the war against drugs and
The aim of this thesis was to investigate the relation between tooth size and dental caries in a medieval material from S:t Clemens cemetery in Lund. Dental caries is one of the most common infectious disease in humankind, both in prehistoric and modern populations. Evidence of caries gives the opportunity to study health and diet in populations. During evolution of humankind, there are evidence o
While environmental change calls for reducing carbon emissions from deforestation, evidence shows that land owned by Indigenous Peoples have much lower rates of deforestation. The federal government in Brazil, however, is taking measures to increase economic benefits of indigenous lands in the Amazon, which could result in weakened IPs’ land rights. In this thesis I analysed Brazil’s president’s s
Studiens titel: Kommunikatörens roll och förhållning - En kvalitativ studie om kommunikatörens förhållningssätt till dagens medielandskap och val av kanal. Syfte: Syftet med studien är att bidra med kunskap kring kommunikatörers synsätt på utvecklingen av kommunikatörsrollen och deras förhållningssätt till samtida kommunikation, förändringen av medielandskapet och kanalval i relation till interp
I gymnasieskolan är det de yrkesförberedande programmen som förbereder eleverna för yrkeslivet. Vid studier på Vård- och omsorgsprogrammet kan eleverna, efter tilldelad yrkesexamen, arbeta inom bland annat hälso – och sjukvården och äldreomsorgen. Eleverna är eftertraktade på arbetsmarknaden, men det finns ett problem. Ett stort antal elever har svårt att uppnå kursernas givna kunskapsmål. Uppsats
Smoothed Aggregation (SA) is a technique from algebraic multigrid methods (AMG) which has shown very promising results when solving systems of linear equations with symmetric system matrices, but suboptimal results for nonsymmetric system matrices. The purpose of this thesis is to investigate the method EMIN(r) and a closely related method EMIN proposed by Sala and Tuminaro. EMIN(r) and EMIN were
I Sverige är det olagligt att på något sätt misshandla, kränka eller utsätta barn för sexuella övergrepp. Trots denna lag är det många barn som far illa vilket leder till både fysiska och psykiska besvär upp i vuxen ålder. All personal inom hälso- och sjukvården har anmälningsplikt vid misstanke om att ett barn far illa. Studier visar att hälso- och sjukvårdspersonal underrapporterar till socialtj
