Mantena Sverige AB is responsible for providing maintenance to Skånetrafiken’s trains. The maintenance is done in their depot located outside of Helsingborg. Previously all sourcing and inventory control of spare parts used for repairs has been done by the company who built the trains and who has a warehouse located in the same building as Mantena’s depot. However, Mantena is currently in the proc

Vid anläggning av djupa borrhål med tryckluftsdriven sänkhammarborrning transporteras oundvikligen bortborrat berg blandat med grundvatten upp till markytan. I Sverige spolas kaxvattnet oftast ut i en cirka 10 m3 stor container för att de grövsta partiklarna ska sedimentera innan vattnet pumpas vidare. Efter grovavskiljning kan vattnet fortfarande innehålla höga halter av suspenderade partiklar. IWhen drilling a borehole using a down-the-hole hammer driven by pressurized air drill cuttings mixed with groundwater are unavoidably transported to the surface. In Sweden the most common practice is to flush the waste water out into a roughly 10 m3 container where the coarsest particles can settle before the water is pumped away. After separating the coarsest particles the waste water can still c

En undersökning av när det tidigare kongruerande mycken försvinner och ersätts av dagens mycket. Även fördelningen av så kallade inherenta singularer och pluralord undersöks i förhållande till denna förändring.

Technological development and capabilities are driving IT costs up for many manufacturing companies. The importance of having a lean and efficient IT organisation in place is therefore of increasing importance in order to control these costs. This study aims at investigating how large manufacturing companies most effectively can tackle the challenges of a growing pressure on the IT department to d

Background Sub-Sahara Africa has seen tremendous economic growth the last years. Between 2001-2011 six of the world’s fastest growing economies were in Sub-Sahara Africa. This makes the region a very attractive market for firms and investors interested in growing their business. Purpose: The purpose of this thesis is to identify the key factors that affect growth for firms that are active or plann

The area management responsible for the United Kingdom, Ireland, and the Nordic region within the Company expressed a desire to identify new business opportunities in the Nordic region. The motive was to use the identified opportunities as an argument for additional resource allocation to the Nordic region. In previous years, the Company has performed a number of projects focused on identifying op

Purpose: The main purpose of this thesis is to increase the understanding of how companies in general, and for the Case Company in particular, can identify and analyse value-adding opportunities to an existing business model. Sub purposes: - Create and suggest a theoretical framework in order to identify and analyse value-adding opportunities to a business model. - Identify and analyse value-addin

Several studies show difficulties that companies have in pursuit of annual growth. The same studies show that companies that succeed are those that focus on innovation and continuous product development. Atlas Copco is one of Sweden’s largest companies and the brand stands for sustainable product development. This examination project has been executed for one its daughter companies, Atlas Copco Co

Background The EU’s 20-20-20 targets determine that Finland’s share of energy consumption from renewable energy sources is to be 38 % by 2020, a target that the government intends to reach by expansion of wind power. The government has a beneficial feed-in tariff in place as an incentive for rapid wind power expansion, which has made both domestic and international developers evaluate the business

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
