As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

The study focuses on mapping how well prepared the counties in the west region of Sweden is in case of restructuring. The study explores what kind of activities and routines that contributes to prepare the organization for restructuring. The study also aims to investigate the effect of precedent restructuring, and if the counties who experienced restructuring are more prepared than others.The research within the field of restructuring characterizes of an evaluating nature and the focus has been after the restructuring occurred. There have also been a lot of studies of the negative consequences on individual and organizational level. Since downsizing is a frequently used method by management despite its consequences is it important to investigate how organizations can learn and thereby be more prepared for restructuring.

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

Byggbranschen står inför stora förändringar i framtiden i och med att BIM (Building Information Model/Modelling/Management) successivt introduceras inom området. BIM innebär en förändrad arbetsmetod som kan ge förbättrade möjligheter att minska tidsåtgången och omarbetningar i ett förprojekteringsskede samt skapa ett effektivare projekterings- och produktionsskede med färre fel. BIM är ett relativt nytt sätt att inom byggbranschen bedriva projekt och innebär en förändring för olika skeden inom byggprocessen vilket påverkar inblandade parter.Syftet med denna studie är att ta reda på hur Peab i Kiruna på bästa sätt kan nyttja möjligheterna som finns med BIM samt redogöra för några av de förändringar BIM kan innebära jämfört med nuvarande arbetsmetoder.En teoretisk del beskriver BIM och dess för- och nackdelar inom olika områden samt vilka hinder det finns för arbetsmetoden. Ett resultat baserat på den teoretiska delen förklarar att BIM i dagsläget främst bör nyttjas av Peab i Kiruna i ett anbudsskede, där ett förfrågningsunderlag görs om till en BIM-modell. Detta kan leda till underlättande för företaget att se fel i förfrågningsunderlag samt att utförande av mängdavtagning och kalkylering kan ske på ett enklare sätt.

Abstract Emma BergdahlObstacles and opportunities among occupational health nurses when implementing healthy eating habits.C thesis in Public Health. Faculty of Health and Occupational Studies. University of Gävle. Autumn 2012 Objective: The purpose of this study was to investigate which obstacles and opportunities nurses within occupational health find when trying to implement healthy eating habits among the employees in their respective company. Another objective was to see if the nurses worked according to the Guidelines, issued by the National Board of Health and Welfare.Method: The study was a quantitative study and conducted among nurses in central Sweden.

REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s trucks. Today, the GPS-systemconsists of an active antenna mounted on the roof of the truck. The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.

Background: Good health at community and individual levels are key policy priorities. These priorities can be shown through supporting parents about various different healthy lifestyle choices. In order to know where interventions are needed, it is of interest to study how parents generally feel and how they perceive their parenting.Aim: To study how parents rate their own health and parenting skills, and examine whether there is any correlation between perceived general health and perceived parental competence.  Further, this study will show whether there is a correlation between rate of perceived general health and rate of perceived parental competence when it comes to gender.Method: 64 questionnaires were collected at strategic open kindergartens in the municipality of Uppsala. The questionnaires were distributed to the parents present and who chose to participate in this study.Main result: The result of this study shows that parents have a high rate of general health.

Authors: Lars Johansson & Johan PetterssonTitle: ?There is way to much sports in the athletics? ? A study of Swedish sportsFootball has gone from being a hobby and a popular pastime into a billion-dollar industry, and clubs around Europe are therefore operated more and more like regular companies. Sweden's position in the UEFA rankings is a modest 23 rd place, behind nations such as Austria, Switzerland and Belarus. The economic climate in Sweden is often highlighted as a strong factor. When we started our study we agreed that this could be a major contributing factor to this relatively modest rank, but believed that there were also other factors that played a big role.

Because social media is personal and reaches users directly, it has become an important means of communication for companies trying to reach out to their audience (Nygren & Wadbring, 2013). Especially the possibility of interactivity has been discussed as social media's big advantage. But how much two-way communication is actually possible on social media? This is a quantitative study that focuses on how Swedish Facebook users in the ages of 16-25 interact with companies on the social network. The aim was to contribute with increased information and knowledge about how the users mentioned above interact with the companies as well as how the users perceive the companies communication and presence on Facebook.

Abstract Our intent with this study was to find out what changes have been made during the last 30 years in the way that the media reports from certain events. We choose to study the world of football and specially the Swedish national team and it?s relationship to the Swedish television medium in the World Cup of 1974 and the World Cup of 2006. The study mainly focuses on the differences in commentary and in the production from both of the championships. We used Keith Selby and Ron Cowdery?s book How to study television and Mats Ekström and Lars-Åke Larsson?s book Metoder i kommunikationsvetenskap as tools to analyze the games we watched. The result showed that there?s been a lot of changes media wise between the two championships.

The purpose of this thesis is to describe property definition and special boundary demarcation and to analyze the differences between the two cadastral procedures. Property boundaries, especially unlawfully determined boundaries created through unofficial parcelling, can create conflicts between landowners and make it diffi-cult to know which land that a property contains of. It is possible to clarify the boundary conditions through a property definition or through a special boundary demarcation re-establish boundary marks.The methods used are: (1) A literature review to collect background information, (2) A case study to summarize court cases and (3) A questionnaire study to collect opinions from cadastral surveyors.The result is summarized in two comparisons. Firstly between restoration of landmark and special boundary demarcation (which replaced restoration of landmark in a legislative change in 2010), which demonstrated that the change in the law is considered positive because special boundary demarcation gives a legal effect on the boundaries. Secondly between property definition and special boundary demarcation which demonstrated that the two procedures are similar to each other.
