Purpose: The purpose of this thesis is to develop two simulation models of Arrivas train network in Denmark to facilitate the process of timetabling. One of the models assumes deterministic times in the other model these times are stochastic. The purpose of the deterministic model is to evaluate if timetables are free from conflicts, a process that currently involves a lot of manual labor. The mai

During the last few years, crowding effects on the physics of proteins has become an increasingly popular topic of research. This is is because most biological processes involving proteins naturally take place in a crowded environment, e.g. in the cellular environment where macromolecules may occupy 30% of the volume. One such biological process would be the formation of amyloid aggregates, which

This study analyzes the relationship between electricity prices and energy efficiency in German companies. Economic theory suggests that higher energy prices will lead to higher energy efficiency. This paper tests this hypothesis empirically by analyzing company-level data from Germany. In particular, a special provision of the German Renewable Energy Act (REA) is exploited. According to this prov

The Olserum mineralisation is situated in the metasediments of the Västervik formation, which repre-sents the southernmost continental margin of the Svecokarelian Domain. After deposition between 1.88 – 1.85 Ga these sediments were subsided to a depth of about 10 km and intruded by a series of granitoid melts. The resulting HT/LP metamorphism, with a peak at upper amphibolite facies, transformed t

Children who are victims of sexual abuse is a phenomenon observed by the society. Research proves that children who are sexually abused, the consequences can be more far re- aching than adults who are exposed of sexual abuse. In 2005, a new legislation of sexual abuse act in force that aimed to increase the protection of children and adolescents who are sexually assaulted. The proposal of the new

Problem Definition: The Swedish foresight division, SFD, of Bramble AB is charged with developing concepts for new products and innovations. At the time, this process is generally disjointed from external input from customers about the needs of the target group. Ideas are generated based on hypotheses, proposed by the employees at SFD, after which concepts are developed and tested internally. Howe

Evaluation of the Galil DMC–4080 as a closed-loop controller of a stepper-motor driven Stewart Platform with mm- and mrad- precision and resolution. The project involves a full implementation and optimization of kinematic equations, implementing modes of motion & controller structure, as well the use of MATLAB simulations. The 4080 proves successful in static positioning but have limitations i

Corporate environmental efforts are now valued higher than ever and need to be communicated to customers in a successful manner. Companies today wish to promote themselves as sustainable and use environmental performance to obtain competitive advantages. SKF is promoting themselves as an environmentally sustainable supplier and wishes to ascertain how environmental performance can be communicated

Option valuation is typically done under the unrealistic assumption of perfect knowledge about model parameters. This thesis shows that risk-neutral valuation, while still adressing the parameter uncertainty, can be computed for a variety of models within the Fourier framework. This results in a computationally inexpensive method for valuating options. A study of S&P500 index option data shows

Bakgrund Trafikoperatören Arriva DK befinner sig i en expansionsfas och ser därför ett ökat behov av att arbeta på ett mer strukturerat sätt, i förhållande till tidigare ad hoc-kultur. Beslut har därför tagits att skapa en portfölj innehållande verktyg och processer för att bättre hantera styrningen av företagets bussflotta. Styrningen av en bussflotta kallas även fleet management och examensarbet

This report – is based on a case study – that outlines the importance of Sustainable Business Modell in order to maintain and improve the profitability for small and mediumsized hotels. The result of this report will be based on a small family owned hotel located in Southern part of Sweden – Skanör – that has a fairly great reputation in the area. Hotell Gässlingen is a small hotel with 28 rooms,

Background:The case company Atlas Copco has a decentralized organisation where the product responsibility has been delegated to the Product Line Manager located at the production facility. To manage the product portfolio and make strategic and tactical business decisions related to the products, information about product performance and profitability is a key input. Today, the Product Line Manager

The aim of this research is to explore how equalization of health is envisioned in a Chinese new policy regarding the equalization of basic health care for Chinese migrant workers in order to understand its material effects on the targeted population in terms of citizenship rights and modes of governing. The purpose is furthermore to see whether migrant workers share the health needs and values pr

In a mammography examination, an x-ray image is taken of the patient’s breast. The examination can be painful due to the fact that the breast has to be properly compressed to attain good image quality. To reduce discomfort for the patient it has been suggested to measure pressure distribution over the entire breast. This thesis investigates design and manufacturing of a radiolucent pressure senso

Tidigare forskningsresultat har indikerat att långsiktig underprestation i regel återfinns hos börsintroducerade bolag. Syftet med den här studien är att testa huruvida de tidigare forskningsresultaten också gäller för börsintroduktioner inom teknologibranschen under 2000-talet. Genom att studera börsintroducerade bolags aktiekursutveckling, fastställs prestationen då de jämförs med marknads- och Earlier studies have shown that long-run under performance is occuring for Initial Public Offerings (IPOs). The purpose of this thesis is to test whether long-run under performance is appliable for IPOs within the technology sector during the 21st century. By studying movements in stock prices, the performance is determined when comparisons to indices are made. Further on, the three year buy-and-h

I skolan är kreativitet idag ett av honnörsorden och i kursplanen i musik betonas betydelsen av att undervisningen ska ge eleverna möjligheten att utveckla sin musikaliska kreativitet. Men vad är musikalisk kreativitet? Styrdokumenten ger ingen tydlig vägledning hur begreppet ska tolkas, utan lärare och utbildare är lämnade åt sina egna tolkningar. Syftet med denna rapport är att genom intervjuer In today's school, creativity is a popular word. The Swedish music curriculum emphasises the importance of enabling students to develop their musical creativity. But what is musical creativity? The school's policy documents provide no clear guidance on how the notion of musical creativity should be understood and teachers are left with their own interpretations of the concept. The purpose
