Assessing the probability of rare and extreme events is an important issue in the risk management of financial portfolios. Extreme value theory provides the solid fundamentals needed for the statistical modelling of such events and the computation of extreme risk measures. The focus of the paper is on the use of the peak over threshold method under extreme value theory to compute right tail risk m
GMRES (Generalized Minimal RESidual) är en iterativ metod som löser linjära system, där matrisen är inverterbar. Metoden löser systemet genom att generera bättre approximationer i varje iteration. Detta tillvägagångssätt är intressant i de fall man redan har en bra approximation att utgå ifrån. Med tillräckligt bra approximation kan ett väldigt stort system lösas med få iterationer, med en given tIn this thesis a GMRES method is constructed and tested. The method is implemented in a C++ program with the MPI protocol to make it parallel. The parallel parts of this program are discussed in detail, especially the communication and the partitioning of the data between the processes. In the tests that were conducted we come to three important conclusions: the method works as expected, a substan
Inspired by environmental peacebuilding literature, this research explores the peacebuilding potential of natural resources through a qualitative case study of a conflict-affected community’s transition of livelihood strategies from coca cultivation to butterfly farming. The fieldwork was carried out with peasant families in rural Otanche - a biodiversity-rich area that, besides the Colombian conf
In order to enhance the accountability and legitimacy of public research, performance-based research funding systems have been introduced in numerous countries during the last decades. Although this development has gathered considerable interest in recent years, it is thus far not clear how performance measures shape research practices and academic subjectivity. Combining bibliometric studies and
This paper investigates the relationship between capital structure and stock returns for Swedish firms listed on the Nasdaq OMX Stockholm Stock Exchange. Actual stock returns and leverage figures in form of total, long-term and short-term debt are used in the calculations. The results suggest, in contrast with a majority of fundamental theories, that there is a negative relationship between levera
The purpose of this report was to study how two common types of wood stud walls in Sweden will handle the future climate in Sweden, Gothenburg, out of a hydrothermal point of view. These two walls were analyzed with simulations in the hydrothermal calculation software WUFI with varying parameters. The first cases of the simulations were the so called base cases where moisture- and heat-sources was
Purpose: To propose a blueprint of how the policymakers responsible for health care reforms in the county of Scania (Sweden) could evaluate a prospective stroke care intervention from a societal point of view. More specifically, the intervention will consist in the introduction of telemedicine technology to their ambulance fleet. In addition, key methodological issues, of interest to the policymak
The social and environmental impact associated with consuming a product is something that is becoming increasingly important to consumers and businesses alike. This impact can in theory be computed simply by classifying a product and by mapping the classified product to the corresponding life-cycle assessments research. However, this type of mapping requires an extensive product taxonomy with a la
Samhällsbyggnadsbranschen har arbetat med att införa Byggnadsinformationsmodellering(BIM) i mer än tjugo år och under de senaste åren har BIM börjat implementeras på riktigt. Syftet med studien är att undersöka möjligheter inklusive hinder och framgångar inom arbetssättet BIM vid implementering i produktionen. Vid övergången från projektering till produktion ska undersökningen hitta de brister som

Sammanfattning Titel: Ägarstrukturens betydelse vid förvärv – en studie om hur ägartyper och ägarkoncentration påverkar långsiktigt värdeskapande vid förvärv. Seminariedatum: 2014-05-22 Kurs: FEKN90, Examenarbete på Civilekonomprogrammet, 30 högskolepoäng Författare: Daniel Eskilsson & Sofia Nyrén Handledare: Rikard Larsson Syfte: Syftet med denna studie är att undersöka huruvida svenska förvä
Det ökande användandet av BIM leder naturligt till att programvaror behöver utvecklade funktioner och nya möjligheter. Fördelen med BIM är att en konstruktions alla egenskaper kan samlas i en och samma modell. Rimligtvis bör modellens geometriska information även enkelt kunna användas vid en strukturanalys. Däremot innehåller en beräkningsmodell i regel en rad förenklingar av geometrin, för att påIFC is key enabler for data interoperability of BIM models. This enables reusing the geometry for structural analysis, thus saving modeling time. BIM models and the IFC format consists of solid elements, therefor the imported geometry will generate solid elements when meshed. When performing structural analysis with the finite element method on concrete structures the use of shell and beam element
A qualitative investigation of the first implementation stage of a large-scale change project towards process standardisation and associated change management efforts within Alfa Laval AB. The goal of the research is to contextually analyse the dimensions of change, investigating how the misalignments of the understandings of change and change management come about and what they imply for the chan
Uppsatsens syftar till att undersöka om ägarstruktur har en påverkan på offentliggörande av information bland bolag på Stockholmsbörsen. Syftet är att se om olika typer av ägare påverkar hur mycket information som offentliggörs i företags årsrapporter, delårsrapporter samt på deras hemsidor. Den teoretiska referensramen utgår från teorier kring effektiva kapitalmarknader, informationsasymmetri, pr
The thesis undertakes an analysis of the current tension between patents law obligations under TRIPS Agreement and human rights, specifically in the context of how the TRIPS Agreement influences health innovation and access to medicines in Brazil. Following a general overview of the interaction between human rights and patent law within the WTO, the central aim is based on the empirical analysis o
Syfte: Att beskriva och förklara hur mindre revisionsbyråers tjänsteerbjudande har påverkats av att revisionsplikten avskaffats för mindre aktiebolag. För att kunna förklara detta undersöker vi också varför revisionsbyråernas utveckling ser ut som den gör. Vidare beskriver vi hur revisorns roll på mindre revisionsbyråer har förändrats sedan avskaffandet. Metod: Vi har utgått ifrån en kvalitativ f
This paper investigates the determinants of the credit default swaps changes of 34 European banks between January 2004 and December 2013. The sample period is further divided into four sub-periods covering both calm and turbulent times (pre-crisis, acute phase and less acute phase of the financial crisis, and the most recent European sovereign debt crisis). We show that CDS spread changes are not
This paper addresses the issue of gendered identity as presented in Charlotte Brontë's first and last novels, The Professor and Villette. As both of these novels are fictional autobiographies, and as the former is narrated by a man and the latter by a woman, they serve as good objects of analysis in that each of them represents its narrator’s understanding of him- or herself. Taking nineteenth
The empirical study reported in this essay concerns Swedish university level learners of English as a foreign language (EFL) and their lexical inferencing skills, that is, their ability to guess the meaning of unknown words in a running text using different types of knowledge and textual cues (Haastrup, 1991). More precisely, the present investigation explores the relationship between students’ in
