Vi spenderar stor del av livet i urbana miljöer och majoriteten av landets befolkning påverkas dagligen av utformningen av stadens rum, vilket gör det intressant att undersöka hur stadskärnorna är utformade. Handeln i stadskärnorna förlorar idag mar knadsandelar till externa köpcentrum och e-handeln. För att förändra handelsplatser i stadskärnor till att bli mer attraktiva och konkurrenskraftiga kThis study aims to explain the structure and content of Swedish city centres. The distribution and density of commercial activities in the cities are analysed with network constrained methods (Kernel density estimation, Ripley’s K-function and centrality measures) in GIS-programs. External shopping centres and economic theories are used as a benchmark against which city centres are compared. The

This rapport investigates the transmitter of the Ericsson Bluetooth radio. The open loop modulation scheme of the existing design is theoretically very simple but difficult to implement with available components. Frequency drift of the carrier is a common result of open loop modulation. This work therefore investigates an idea of frequency regulation where the regulation is active during modulatio

Populärvetenskaplig sammanfattning En förändring i det rådande klimatet med en temperaturhöjning på grund av en ökad atmosfärisk CO₂-koncentration kan komma att ha en påverkan på skogar över hela jordgloben. Trädarter som är anpassade till ett visst klimat kan komma att spridas norrut då klimatet kan vara mer passande i framtiden. Detta medför risken att lövträd från central Europa kan konkurrera A climate change will affect the forests around the globe; there may be competitions for available resources that are needed for growth and dispersal. Europe is supposed to be more sensitive and may experience a greater influence than many other regions. As an additional effect of climate change extreme weather events will be more frequent e.g. drought and extreme precipitation that will cause flo

Short-term tourists visiting formerly residential areas are a potential source of conflict as the short-term tourists change the place they are visiting and represent an inconvenience to residents. This research uses a mixed methods approach with the short-term rent gap framework introduced by Wachsmuth and Weisler (2018) as the quantitative and an additional online expert interview as the qualita

Skattelättnadsregeln för medlemmar i oäkta bostadsföretag, som togs bort från och med inkomståret 2016, innebar att de kunde göra ett avdrag på den beskattningsbara bostadsförmånen. I och med borttagandet av denna regel påverkas cirka 5000 privatpersoner av en högre utgift för sitt boende. Att en bostadsrättsförening klassas som ett oäkta bostadsföretag beror ofta på att de har en stor andel lokalUp until recently, members of co-operative housing associations with a high income deriving from non-housing activities could benefit from a tax exemption rule. This rule was last applied in 2015 and meant that a deduction could be made for the taxable housing benefit. With the removal of this rule approximately 5,000 private individuals are affected by a higher cost for their accommodation. When

Sveriges vattenledningsnät kräver kontinuerliga och stora in- vesteringar och måste underhållas på ett effektivt sätt; syftet med den här studien var därför att utröna vilka ledningsattribut som är viktigast för att i en ANN-modell identifiera ledningar med hög risk för läckage. Detta gjordes genom att först använda attri- buturvalsmetoderna ReliefF och Recursive Feature Elimination (RFE) tillsammanSweden’s water pipe network demands continuous and large investments and must be maintained in an effective way; the aim with this study was therefore to investigate which pipe features are most important to identify pipes with a high risk of leakage in an ANN-model. This was done by first utilizing the feature selection methods ReliefF and Recursive Feature Elimination (RFE) with Random Forest Clas

At the time for the starting point of this master thesis, the Electrolux Healthy Home department where at a high extent looking into how a system of products that could communicate with one another could give the user a better experience in the home. Products that where looked into for coupling where for example an air purifier with a robotic vacuum-cleaner, maybe also coupled with any other

Abstract The current Standard Model of particle physics contains few interactions resulting in a final state with two leptons with the same charge. Any observation of an excess of such same-sign dileptons would be an indication of new physics processes, making it a useful channel when searching for exotic physics. This thesis presents three projects conducted within the ATLAS Same-Sign Dilepton gr

The condition of the Swedish railway has been frequently discussed, mainly during recent years. Lack of maintenance and budgetary allocation are words that constantly arise. During the winter the topic is notably higher, especially because of the media that regularly reports about cancelled and delayed train departures. This thesis will plunge into the difficulties that the railway sector will fac

In the last couple of years it has become more and more common to use control theory in computing systems, for instance operating systems, web servers and databases. The reason for this is to make these systems more robust and stable. This is of interest because we today are more dependent on computing systems in our everyday life, and therefore put higher demands on them. A lot of focus has been

Sweden, often listed as one of the world’s most gender equal countries, has one of the most gender segregated labour markets in the world, as well as one of the largest gender differences in regard to the number of days with parental leave. This paper investigates whether there is an interaction between occupational groups’ gender composition and the effect of average days with parental leave on t

Augmented Reality (AR) is a new and exciting technology with wide potential implementation areas, from medical to industry. One of the fields from which AR is gaining attention is the manned security industry. Unfortunately, this is also one of the areas in which formal studies on AR is lacking. Ais study aims to bridge the gap in knowledge by evaluating an AR-application designed for the Microsof

Purpose: The purpose of the thesis is to examine how the pay-performance relationship behaves for firms listed on the Stockholm Stock Exchange large cap list and attempt to draw inferences about how nation-specific aspects characterizing listed Swedish firms affect the relationship. Method: The method is a regression analysis using regressing performance on pay along with the control variables fir

We wanted to examine children's views on families and traditions surrounding family formation. Our main questions were; What are children's views on the concept "family" and how does this compare to the different definitions of family? How traditional or modern are children in comparison with historical and present views? and What are the effects of their own experiences, and val

Abstract The media sometimes give a dark image of Swedish elderly care. Responsibility for the care of the elderly is put on the managers. Apart from budget matters, they are responsible for staff as well as care-takers. The aim of this study was to examine the manager role at homes for the elderly from the point of view of the managers themselves. The material consists of six semi – structured in

Objective: The use of cytological specimens to evaluate tumour biomarkers in metastatic breast cancer lesions has attracted increased interest because of the considerable number of reports that have shown discordance between the primary tumour and metastatic lesion. Oestrogen receptor (ER) and progesterone receptor (PgR) assays are crucial for the management of patients with breast cancer, in bot

Nerve injuries extend from simple nerve compression lesions to complete nerve injuries and severe lacerations of the nerve trunks. A specific problem is brachial plexus injuries where nerve roots can be ruptured, or even avulsed from the spinal cord, by traction. An early and correct diagnosis of a nerve injury is important. A thorough knowledge of the anatomy of the peripheral nerve trunk as well

The concentrations of ''free'' chloride and hydroxide ions in extracted pore solution from concrete exposed and submerged in a marine field station were studied by the pore solution expression method. In addition, the corresponding concentrations of total acid soluble chloride in the concrete was analyzed. The relationship between total and free chlorides was analyzed and compared with similar dat

Purpose: Use of mechanical imaging (MI) as complementary to digital mammography (DM), or in simultaneous digital breast tomosynthesis (DBT) and MI - DBTMI, has demonstrated the potential to increase the specificity of breast cancer screening and reduce unnecessary biopsies compared with DM. The aim of this study is to investigate the increase in the radiation dose due to the presence of an MI sens

Coherent synchrotron radiation (CSR) is generated when the electron bunch length is in the order of the magnitude of the wavelength of the emitted radiation. The self-interaction of short electron bunches with their own electromagnetic fields changes the longitudinal beam dynamics significantly. Above a certain current threshold, the micro-bunching instability develops, characterized by the appear
