Credit risk modeling is an important part of the nancial protection used by banks during times of turbulence in the economy. More precisely, the modelling is about estimating how much economic capital a bank needs to hold in order to survive during an extreme loss. This thesis is about improving the robustness for the estimation of the economic capital, when it is updated as time passes. A decreas
I studien framgår det att i problematiken som organisations- och styrprinciper inom hälso- och sjukvården har skapat är det verksamma chefer som anpassar och styr verksamheterna för att hantera just denna problematik. Genom att utforma egna hybridorganisationer där de verksamma cheferna kombinerar olika organisationsformer skapar de en struktur anpassad enligt verksamhetens kontext. Samtidigt infl
Efter en regeländring i inkomstskattelagen i juli 2003 gjorde en ny typ av fastighetsförsäljning entré på marknaden: paketering, vilket innebär att en fastighet säljs i bolagsform snarare än som fast egendom. Genom detta förfarande blir fastighetstransaktionen skattefri (eller lågt beskattad), vilket också har lett till att paketering numera är en vanlig företeelse i Sverige. Detta innebär en uteb
Företag har traditionellt koncentrerat sig på den tekniska biten av IT-säkerhet, med brandväggar, virusskydd och så vidare. Men eftersom många säkerhetsincidenter sker på grund av att företagets anställda inte följer företagets informationssäkerhetspolicy bör IT-säkerhet även innefatta den mänskliga faktorn. Med min studie så vill jag undersöka hur anställda uppfattar hur de sociala banden på arbe
I vår uppsats har vi tittat närmare på sprint retrospective meetings som är en av ceremonierna i den agila utvecklingsmetoden SCRUM. Vi har undersökt vikten av att använda sig av ett målfokuserat arbetssätt och om det är nödvändigt att sätta upp mätbara mål för att nå framgång i retrospektet. Genom en litteraturstudie har vi skapat en generell bild av vad ett retrospekt ska innehålla och hur man p
This paper aims to evaluate recent policy updates in a credit scoring model and determine if the new model is efficient, as well as further investigate other potential risk factors. In order to evaluate the policy changes, the proprietary dataset is first categorized and estimated by a logistical regression model and secondly the dataset is transformed according to new policies and then simulated
Med mer kraftfulla grafikkort har möjligheterna utökats för vilka grafikmetoder som kan utföras i realtid. För en sådan metod, raytracing, används speciella data- strukturer, och för att kunna användas i realtid behöver dessa byggas upp snabbt.The Bounding Volume Hierarchy is an acceleration data structure used in ray tracing, allowing for faster intersection tests between rays and triangles. The goal of this thesis was to take one algorithm for rapidly generating such data structures, the Bonsai algorithm, which was initially implemented on a CPU, and instead implement it on a graphics processing unit. Many parts of the al- gorithm go
In this thesis a cognitive application is developed using IBMs cloud platform Bluemix and its Watson services. The goal of the application is to make it easier for bloggers and journalists to publish online during conferences. To reach the goal the application was designed with, among other things, functionalities for speech to text, publish on social media and automatically generated hashtags. Th
This thesis has been performed at MediYoga International. Company’s concept is centered on education of instructors and other personnel in stress reducing methodology. The methodology is based on scientific studies of yoga and has well documented effects. The main reason for long-term sick leave in Sweden today is burn-out, as a direct consequence of continuous stress witch is supported by many sc
The Women, Peace and Security agenda (WPS) argues for women’s rights and recognition of women’s situations in all stages of a conflict. Previous research has shown how refugee women seem to be overlooked in international legislation. Existing research considering the WPS agenda has mainly focused on issues of implementation and discourses. This study aims to explore how conceptualizations of secur
In this thesis the translation of (im)politeness and honorification from Japanese is examined. Due to the different and complex politeness system in Japanese compared to European languages, difficulties rise in translating texts containing it. The goal of this thesis is to analyze the strategies used and the outcome, while comparing the translations of the novel Norwegian Wood made to three differ
The paper is about how society effects art when society goes through different social processes. The study is limited to the period referred to as the Vasa era and to paintings. What is meant with Vasa era is the 16th century. During that period, society goes through a social centralization in Europe and the question arises if this is, or becomes, noticeable in the art. This is another angle on so
In this Master's Thesis we study Semi-Riemannian Geometry. More speci cally, this is done by discussing some well-known classi cation theorems from Riemannian geometry and then showing some counter-examples to these in the semi-Riemannian setting. In particular, we brie y discuss the theorem by Hopf and Rinow, and give a counter-example to this in the semi-Riemannian setting. Moreover, we stud
In 1997 the UK government launched the Sure Start early year’s intervention scheme, offering early years education, health services, adult employment advice and free or highly subsidised child care located in one convenient service available to the most deprived areas. The aim was to improve the life chances of the most disadvantaged children, but also to increase employment for mothers of young c
In 2013 the Swedish Police authority and district administration in Angered, a district in Gothenburg, initiated the operation Trygg i Angered with the aim to increase the safety of the residents. Based on security studies from the years 2013-2015 illegal and reckless driving of mopeds has been a major security problem in Angered. The municipality has targeted action on illegal and reckless drivin
The objective of this thesis was to develop a flexible optimization framework for district heating networks (DHN) and to introduce pressure in the network models. This was done by creating a network represen- tation (NR) of the networks using the Python package NetworkX. Each node represents a customer or producer and the lines between the nodes are the corresponding pipes. The method of the proj
This research aims to give a thorough look at the incidence, and evolution of occupational mismatch in the Spanish labor market from the 1990s till 2013. This is done by examining which parts of the labor market have been exhibiting this feature, and what the odds are of being mismatched, given individual characteristics. Two, large micro-data surveys were used; the Wage Structure Survey (WSS) and
För drygt 40 år sedan kom en stor grupp flyktingar till Tanzania från Burundi. Om man räknar in barn och barnbarn omfattar den här gruppen idag ungefär 200,000 personer. I oktober 2014 blev de medborgare i Tanzania. Min studie undersöker vilken skillnad det gjort för några av dessa personer att bli medborgare jämfört med att vara flyktingar när det kommer till deras levnadssituation och möjligheteThe purpose of this study was to find out how attaining citizenship had affected livelihood opportunities and strategies among the approximately 200,000 Burundian refugees who after more than 40 years in exile became Tanzanian citizens in late 2014. It is a case study of local integration and development, analysing the situation for new Tanzanian citizens through the sustainable livelihoods framew
