Spårväxeln är en viktig komponent i järnvägsanläggningen som möjliggör byte mellan spår. Att växeln fungerar väl är viktigt ur trafikeringssynpunkt då den största delen av trafiken någon gång måste byta spår under sin färd mellan två destinationer. Problemen kan bli påtagliga med en icke-fungerande växel vilket orsakar försenade/inställda tåg och resenärer som kostar samhället pengar. Att införa n

The construction industry accounts for a large proportion of the world’s total anthropogenic emissions of greenhouse gases, CO2 among others. As a part of the effort to combat this are environmental certifications which have become increasingly more numerous and more frequent in use. This is partly because consumers have become more environmentally aware and motivated to pay more for products and

Buildings has both a cultural-historical and technical value. Buildings that were built in the 60's and 70's had relatively simple energy requirements compared to today. A large part of these buildings need to be renovated. Culture-marked buildings makes the process more difficult due to the cultural- historical value. This means no exterior work can be done, the retrofitting energy effici

Timber-concrete composite floors have been used for many years outside Sweden, although this kind of floor has not reached its full potential in Sweden. An advantage of using a timber-concrete composite floor is that the concrete is primarily subjected to compressive stress while the wood is primarily subjected to tensile stress, for the case of vertical load. The purpose of this work is to examin

The purpose of the study is to find out how construction companies are affected by the hiring of foreign subcontractors. The report investigates the potential risks and what advantages and disadvantages there are construction companies to procure contracts in the international market and especially in North Europe. The work will result in a report that will have the layout of a manual regarding th

This degree project focuses primarily on the requirements related to energy and the environment that are associated with buildings. As a small contribution towards a more sustainable society, piping insulation used for insulating heating or cooling systems has been studied. During the lifetime of a building, these systems can result in large energy losses that cause significant environmental impac

Based on the background of complexity of China's foreign trade structure, the author will make an analysis and outline the contours of China’s exchange rate problems. By using several relevant quantitative mathematical models to find out the relation between RMB exchange rate and USDX, then to analyze their impacts on Chinese foreign trade. This research can check the influence of the microstr

With a multitude of platform and operating system combinations available to- day, ranging from laptops and workstations to tablets and smartphones, users want to use their favorite applications regardless of device. Cross-platform development has thus become more important in recent years. When devel- oping a new application the developers must decide what platforms to support and what strategy to

The aim of this paper is to provide answers to questions related to valuation accuracy and error determinants by investigating the US market over the last 15 years (2000-2014). The first questions are related to the market efficiency in its weak form, while the rest of the paper is focused on valuation accuracy using the multiples approach and the error determinant variables that can influence the

Adapting to climate change impacts is crucial as changes due to climate change are already locked in and will occur independently of reductions of greenhouse gas emissions. Recent studies in climate change adaptation literature have cited that social learning is beneficial for increasing adaptive capacity. The capacity for social learning is governed by the degree of flexibility of the institution

In our technology-based society, there has been a clear focus on technical weaknesses to information security. This study will present another danger that is just as important to be aware of and is just as lethal, Social Engineering. This is an attack against the human element of security. This study covers a basic description of social engineering as well as a more thorough description of how the

Hur grön är Sveriges ekonomi? Sveriges ekonomi rankas både högt och lågt av index över grön ekonomi. Framgångarna beror minskade utsläpp och ökad tillväxt på hemmaplan – men landets import av varor utomlands ger ett högt ekologiskt fotavtryck. Sverige rankas högt av flera internationella index över grön ekonomi på grund av en ökande ekonomisk tillväxt och minskade utsläpp av växthusgaser inom lA green economy refers to an economy that is able to create economic welfare, while at the same time being environmentally sustainable. Some indexes, like the Global Green Economy Index and the OECD Better Life Index, ranks Sweden high in this area, while others, such as the Global Footprint Network, ranks the country low. The purpose of this thesis is to critically examine why Sweden receives div

Studiens syfte har varit att studera våldsutsatta kvinnors bemötande av polisen samt vilka behov kvinnan ger uttryck för, under och efter den våldsamma händelsen. De frågeställningar som har berörts är följande: Vilka upplevelser har de våldsutsatta kvinnorna avseende polisens bemötande i Serbien och hur påverkar mötet med polisen den våldsutsatta kvinnans vidare utredning? För att kunna svara på The study's purpose has been to, based on abused women's experiences, examine their experience of the encounter with the police in Serbia and their needs, during and after the the violent incident. The questions for this study were following: What experiences does the abused women have regarding police treatment in Serbia and how does the encounter with the police affect her further invest

Uppsatsens syfte var att undersöka testet Krona/Klaves användbarhet för att identifiera oro och rädsla hos barn. Testet syftar till att identifiera barn som drivs av rädsla och oro i konfliktsituationer genom att undersöka hur deras svarstid förändras när konflikten blir allt viktigare. Testet utgår ifrån teori om Behavioral Inhibition System (BIS) som menar att en central funktion för en individ The purpose of the study was to examine the test KronaKlaves usefulness to identify worry and fear in children. The test aims at identifying children who are driven by fear in conflict situations by examining how the answer latency changes in the child when the conflict gets more important. The core concept of the test is the Behavioral Inhibition System (BIS) which states that a central function

Purpose: The purpose of the thesis is to fill the research gap as previous research on the topic of interest lacks a country specific research on how culture effects standardization vs. adaptation by MNCs in emergent markets, in context to a specific advertising strategy. By providing a unique cross-cultural study on five different emergent markets (China, Pakistan, Mexico, Turkey and CWAR) the re

The recent global financial crisis has once again shown how fragile the financial system is. This essay investigates the credit risk in the Nordic banking sector by measuring the probability of default of the six major Nordic banks. This is done by using the Merton (1974) model which utilizes stock prices as well as balance sheet data. The results are compared with an approach first suggested by H

Den ökande mängden förorenade områden runt om i världen har blivit ett allt större problem. Risken att människor, djur och miljö exponeras för skadliga ämnen ökar, liksom de kostnader som krävs för att åtgärda dessa områden. För att kunna prioritera de värst förorenade områdena för vidare åtgärder använder man sig i Sverige av Naturvårdsverkets Metodik för Inventering av Förorenade Områden, MIFO. The great number of polluted sites has become a big issue for many countries around the globe as the risk of people being exposed to hazardous substances follows. To deal with the problem within Sweden the Swedish Environmental Protection Agency (Naturvårdsverket) has developed a unified Method for Inventory of Contaminated Sites, called MIFO. In this study a number of inventories that were made

CFD simulations of direct gas injection, especially in large dual-fuel engines, can be expensive both regarding time and computational power. The nozzle area needs to be resolved with a fine mesh to capture all phenomena and for a full engine model this results in a large amount of cells. A method using a Lagrangian Particle Tracking (LPT) approach was developed to handle gas injection by injectin
