We present a multifactor model of the affine term structure of interest rates with dynamics of macroeconomic factors following the diffusion process in the Vasicek model. Using observable series, we investigate the goodness of fit of the model and the impact of the variables on bond yields. We describe in detail the derivation of the model and the numerical techniques for estimating it. We find th

Skelettskintigrafi är en bildgivande undersökning liknande röntgen, där cancer metastaser och andra benskador visar sig som hotspots. Att identifiera dessa hotspots är en svår uppgift även för erfarna läkare. I detta arbete används faltningsbaserade neuronnät till att träna datorer att hjälpa läkare identifiera hotspots.The main goal of this thesis is to design and implement a convolutional neural network (CNN) to classify whether hotspots in bone scintigraphy images represent cancer metastases, caused by prostate cancer, or some other physiological process. A side task was included, where another CNN was designed and trained to classify whether a bone scintigraphy image image is acquired from the front of the pa

The failing firm defence is a tool that an antitrust authority can use to approve a merger that usually would have been blocked if one of the merging firms is failing. The defence has during the last years been used a number of times on EU level as well as in Sweden. This thesis explains how the Cournot model can be used to analyse the failing firm defence. It also presents and discuss’ literature

With today's sustainability thinking and environmental awareness, it is more important than ever to customize even our railway, with its components, for tomorrow's needs. An investment in the replacement of light source is not only an environmental and economic benefit, but also a win for the maintenance. We have chosen in this thesis to investigate why LED technology is not yet incorporat

The part of a structure which separates two floors is called a slab. A type of concrete slab that is becoming increasingly popular is hollow core slabs. A hollow core slab consists of slabs of 1,2 m width placed next to each other, and the space that is created between the slabs is filled with concrete after mounting. The hollow core slab transfers horizontal forces, such as wind load and earth pr

Member State financing of public broadcasters has long been a contentious issue within the European Union, which strives for an open marketplace where broadcasters of different origins move and compete freely. The public financing of certain broadcasters – reinforced by the Amsterdam Protocol and Member States’ desire to maintain and enhance democracy as well as social and cultural values – poses

Uppsatsen syfte är att undersöka hur en lokal Röda Korset krets kan organisera sig och samverka med andra organisationer i ett postmodernt samhälle samt undersöka hur de frivilliga i denna krets upplever sitt engagemang och vilken betydelse det har för dem i ett postmodernt samhälle. Studien är gjord med en kvalitativ forskningansats och empirin består av intervjuer med fyra frivilliga i kretsen s

In January 2015 the Swedish police force went through the most comprehensive restructure of the organization since it became a public authority in 1965. In connection with the refugee crisis in Europe that culminated in the fall of 2015, the Swedish government decided on the implementation of a law that Sweden would establish a border control. Therefore during the massive restructure, the border c

The Republic of Rwanda has traditionally been a home to three ethnic groups: Hutus, Tutsis and Twas. Clear divides between the groups have been created over the centuries by both inside and outside forces. Each group shares among themselves a collective identity which can be used to rally masses to create tensions in society. This is a development a stability-pursuing state seeks to avoid. In the

Energioptimering utav Ericssons radio NGR Micro G1 Sedan lång tid tillbaka har mänskligheten belastat vårt klimat och ekosystem. Idag känner vi till konsekvenserna av vårt leverne och runt om i världen skrider regeringar och organisationer till verken och styr om vårt samhälle mot en mer hållbar framtid. Man söker ständigt nya lösningar som förbättrar och minskar energikonsumtionen och utsläppen fRigorous studies have been conducted on Ericsson's NGR Micro G1 B2/B25 radio. The radio's part in the telecommunications chain and components within the radio have been determined and mapped according to certain characteristics giving an understanding of their function. The obtained knowledge has been applied in order to make the operation of the radio more energy efficient. This has been

The purpose of this study was to examine how people with personal experience of depression create different kind of discourses and collective identities to the aspirational ”real” depression versus the ”non-acceptable” depression in a big Swedish internet forum. It also examined how the forum writers thought about empowerment versus profesional help as a solution for the ”real” depression. Four fo

Yoghurt is a fermented product form the milk, well known in the world. The fermentation is carried out by Lactic acid bacteria (LAB). The most common are Streptococcus thermophilus and lactobacillus bulgaricus, these bacteria make the milk acid, generating a disturbance in the casein micelles making a solid mass called coagulum. This specific LAB also produces expopolysaccharides (EPS) that form t

I Sverige finns många förorenade områden med klorerade lösningsmedel och Färgaren 3 i Kris-tianstad är ett av dem. Där har tidigare legat en kemtvätt som använt sig av PCE (Tetrakloreten), där spill och läck-age har förorenat stora delar av fastigheten. PCE och dess metaboliter har en tendens att förorena stora volymer, vilket gör dessa ämnen svåra att sanera. Detta mastersarbete inriktar sig på aIn Sweden there are many contaminated sites with chlorinated solvents and Färgaren 3 in Kristianstad is one of them. Previously there has been a dry cleaner at the estate, where PCE (Tetrachloroethylene) was used. Through spills and leakages of PCE, the business has contaminated large parts of the property. PCE and its metabo-lites have a tendency to contaminate large volumes, making these substan

Young people with intellectual disabilities in Indonesia face difficulties living up to the financial and social independence criteria of social adulthood. Many will need care- and livelihood support throughout their adult lives. This case study aims to examine how formal and informal social protection for persons with intellectual disabilities is organized in a semi-urban city in Central Java. So

The aim of this Master's Thesis was to develop a standard for structural testing of implants to be used in transfemoral osseointegrated prostheses, since there is a lack of such standards for this type of implant. The methods used in this project include a literature study, a review of ISO standards, simulations of gait in a software called OpenSim, and a comparison of the OpenSim results with

Decarbonising agriculture is vital to meet the global climate change target of limiting warming to below 2°C above pre-industrial levels. However, the agricultural sector is not a current focus for greenhouse gas reduction. The wine industry is growing and contributes to agricultural emissions. It is therefore important to understand how wine producers can increase their use of low carbon practice
