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.

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.

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.

This essay deals with the principle of surprise warfare and its development as well as the adaptation of military action that had to be made to surprise the opponent in the modern era.The concept of surprise is divided into its components in order to clarify what is required to implement a surprising maneuver, to understand the complex concept and form a theoretical framework for gathering facts in the case study.Development and adaption are demonstrated by a comparative case study where Pearl Harbor illustrates an example of historical surprise and Operation Desert Storm illustrates a modern surprise. The product will then be analyzed in order to detect the development and how military conduct is forced to adapt in order to carry out a surprising maneuver. The results shows that the military action of performing a surprise attack has had a major development and is now carried out in a different stage of the attack..

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.

Det andra syftet med studien är att beskriva några barns och pedagogers konflikthanteringsstrategier i konflikter mellan barn. Studiens metod är att utifrån en hermeneutisk forskningstradition genomföra fokusgruppsintervjuer med barn och parintervjuer med pedagoger. Därefter kopplades resultatet från intervjuerna till litteratur och forskning vi funnit inom området.

The aim of this essay was to create an understanding of teachers strategies to respond to children in economic hardship in school and if these children can participate on equal terms in school. To examine this, we chose to do semi-structured interviews which is a qualitative method. Eight teachers were interviewed from four different elementary schools. In our interviews, we found that all the schools both had elements of inclusion and exclusion, which can result in both equal and unequal terms for participation in school. We also found that the school with the most students in economic hardship had the most inclusive strategies.

This study examines how management consulting firms work with business- and functional strategy and how these strategies are interrelated. More specifically we focus on business strategy (business unit level) and knowledge strategy (functional level) and whether these are aligned or not, i.e. whether strategic congruence exists.A number of recent studies have examined the importance of business strategy and knowledge strategy in management consulting firms separately, but few have pointed out the importance of the alignment between them. With this study we contribute to the strategic field of research with a model that describes how management consulting firms should work with their knowledge strategy given their business strategy. The model is developed through a synthesis between theories in the field of strategic congruence, business- and functional strategies and thereafter tested by an empirical case study of six management consulting firms.
