JastAddJ is an extensible Java 7 compiler built using the meta-compilation system JastAdd. One of the main features of JastAddJ is that it supports modular extensions, making it well suited to use as a base compiler when implementing various types of language extensions or new languages built on top of Java. This thesis examines the possibility of extending JastAddJ with a module supporting the la
The purpose of this thesis is to examine if, from a portfolio perspective, the Value at Risk decreases when electricity is included as an asset to a portfolio of risk bearing assets and if this could have an impact on risk hedging strategies. The portfolio standard deviation used to calculate the Value at Risk is based on a Dynamic Conditional Correlation approach providing a time dependent correl
The number and popularity of graduate trainee programmes has recently increased rapidly in Sweden, while few studies have been conducted on the participants, leading to an incomplete understanding of what implications the programmes have for trainees. We analysed the sense-making of trainees based on a qualitative research design from an interpretative tradition. Data was gathered through 15 semi-
The impact of economic hardship has been proven to be a substantial factor in how people lived their lives in the 19th century Sweden. Equally the second-hand market has in recent studies been shown to have been a substantial part of the 19th century economy. The second-hand market consisting of market institutions such as peddler merchants, pawnshops and auctions were central to how people bought
To most people bitumen is an unknown material although it is the most important ingredient in asphalt pavements, something that everyone knows and uses every day. By merely distilling crude oil a substance is produced with unique properties and durability, which could not have been produced by synthetic means, at least not in those quantities used. The production is not that simple and the raw mat
This thesis processes the Swedish local authorities’ work regarding winter maintenance and its organization. This thesis is also about accessibility for those with functional disabilities and the local authorities’ efforts to provide an acceptable level of the accessibility during winter. The report aims to clarify how the local authorities carry out their work with regard to winter maintenance an
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
