The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

This thesis investigates management accounting systems in a Swedish health care environment. Through a qualitative case study of an activity-based cost accounting system that was introduced in 1994 at S:t Görans Sjukhus, a large Stockholm hospital, the following questions are addressed: What benefits can an activity-based cost accounting system offer the Swedish health care providers? What are the potential problems impeding the implementation of such a system? Main findings: an activity-based cost accounting system can improve the understanding of where costs are generated in the production processes. Comparisons between alternative production processes are improved, and the data may serve as a basis for internal pricing measures. Concerning the second question, difficulty in reconciliating the principles of economic control with the culture present in a hospital is identified as the main obstacle to a new management accounting system..

The purpose of this essay is to investigate how well vision and strategies communicates from division level to underlying business unit levels with focus on the Balanced Scorecard Concept. The investigation was carried out within the ANS division and two of its underlying business units at the LFV Group (Swedish Airports and Air Navigation Services). ANS is responsible for the air navigation services in Sweden and the production of the services is carried out of the business units AER (En Route) and ATA (Tower and Approach). With Air Navigation Services means supervision and conducting air traffic mainly within national air space. The purpose of the services is to insure that air traffic could be carried out in a safe way.The Balanced Scorecard was introduced for the first time in the beginning of the 1990´s.

Bakgrund: Med bakgrunden av företags behov att utvidga sin verksamhetssfär, har företagsförvärv blivit alltmer frekventa och mer omfattande. Speciellt i branscher med snabb utveckling såsom IT-branschen, är detta av aktualitet. Med förvärvsvågors uppkomst, har även ett stort antal av dessa förvärv resulterat i misslyckande snarare än expansion. Förklaringen till detta är mångfaldig och kopplas till områden kring före, under och efter förvärvet. Det som förväntas av ett förvärv, är synergieffekter, det vill säga förmågor av förvärvsobjektet som bidrar positivt till moderbolagets verksamhet.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

Background:Companies are beginning to see the world as their market; not only to seek global opportunities but also to oversee the global competition. Although most people connect globalization to export and import of goods, the globalization process also affect the businesses distinguished by service. The corporations are faced with higher demands of adaptation, which in turn leads to higher needs of skills and knowledge, which of course is very important in business such as the hotel industry. A motivated employee can perform better and furthermore has a stronger sense of belonging to the organization and might therefore be a key to future success of the company.Purpose:The main purpose of this essay is to compare the motivation strategies and reward systems chosen by the management and match this with what the employees are requesting. By doing this we can compare the different objects studied in this essay and furthermore we will be able to see which hotel that has the best match.

The aim of this thesis is to describe digitization of images in two Swedish museums. We want to examine their reasons to digitalize; the administrative and organizational aspects of their work and how they handle the problems of preservation and access to the digitalized images. These problems will be examined through our main questions: Why do the museums choose to digitize their image collections? How are their work organized in terms of staff and economical matters? What kind of software do they use, and which technical solutions do they choose? Which preservation and access strategies for ensuring long-term preservation and access of the digital images do the museums work with? How do the museums select material for digitization? How do they handle the matter of discarding of materials? The study was conducted both by reading text material and interviewing personnel at the two museums. The museums? main reasons for digitization seem to be to protect fragile materials from deterioration and provide greater access to the collections.

Speech intervention for children with language impairment aims to both strengthen specific language skills and to reinforce the ability to participate in interactional contexts. Children with language impairment often have problems in interaction; therefore the contributions of the conversational partner are of great importance. Thus, the demands are high on the speech and language pathologist (SLP) for sense and cohesion in intervention. The aim of the present study was to examine how SLPs and children with language impairment interact in language intervention. An approach influenced by Conversation Analysis was used in order to identify various phenomena that occurred, and their effect on the structure of the interaction was analyzed.Four SLPs, two men and two women, were enrolled in the study.  They participated in intervention with two children with language impairment each, i.e.

Background: The situation for Swedish agricultural production today is characterized by an increased competition, particularly after the country joined the European Union. Swedish agricultural production laws guarantee safe, high quality foodstuffs. However, due to these strict laws, Swedish farmers face higher production costs than their competitors. Meanwhile, cheaper imported goods compete freely on the Swedish market. Swedish agricultural production must find new ways to survive in the increasing competition.

Temporary architecture is an alternative urban planning concept which has been adapted in many cities worldwide during the last decade. There is however no common definition for temporary architecture and it is diversely labelled and applied. In 2013 it also became publicly introduced in Stockholm via the approval of the city's first architectural guideline. Temporary architecture is presented in the guideline as a potential tool for exploring public spaces among other architecture related themes. The ideas for temporary architecture are ambitious and promising. The problem is that they are vague and leaves questions regarding performance unanswered.
