Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

I begin my essay with a story that illustrates how a preschool activity organized on a modular work can be perceived. I describe how the environment has been rebuilt and modified to accommodate one large group of children instead of two smaller groups as before. Management´s justification for the change is that it is carried out to give the children better conditions for their learning, but my understanding is that it also hampers preschool-teachers´ abilities to implement their assignment.I try to understand what benefits module work by examining what well-known researchers believe is important for children´s learning in environmental and preschool teacher´s importance. When I use what I have learned to analyze my story, my opinion is that the change of the preschool activity not have just a positive impact but also entails that preschool teachers find it difficult to be present and in interaction with the children as several well-known researchers notes is important for children´s learning. I discuss how a large and rich environment at the same time can be perceived as incalculable for teachers, which can result in not all of the children being paid attention to in the preschool activity.

This work is designed to monitor developments in the relationship between teacher and student in the school environment, but also outside, from the 1950s until today. The survey was based on four interviews with teachers in the same age, and based on their life stories. Their experiences range from student to novice teachers and a long working life until retirement. In addition, all four children has a parent perspective. The following issues have been focused:                      1.What factors have been crucial in teaching elevrelationens development from the 1950s up     to today?                      2.

This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.

In cooperate with Asko Cylinda we have developed a new heat system too short the processtime and reduce the energy consume in a dishwasher and still have it too be a class AAA.The environment and quality is important for the company too still be the number one onthe market, If they want too keep that position the product developed of new innovations willbe very important. The systems we have developed are more effective and reduce energy uptoo 25 %. The process time is reduced too less than two hours, from the today two andhalf-hour. The solutions are too heat up the rinse water and the dishwater at the same time,with a new heating system and it make are solutions unique and effective. Its good for thedish and the environment.

Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

This candidate essay is built on literature studies and discusses the meaning of the residential yard along with what you, as a landscape architect, should think about when you are designing functional residential yards. To do this I found it necessary to figure out what it is that makes people step outside their own apartment and out into the city?s public places. The reasons for this are numerous and many times individually affected. Something that plays a role in people?s outdoor life and prevents them from spending time outside is the lack of time, the technique of today and the feeling off insecurity.

Syfte: Att studera föräldrars uppfattning om den preoperativa information de får inför sitt barns planerade operation, samt undersöka om och på vilket sätt föräldrarna anser att informationen behöver förbättras.Metod: Kvantitativ, deskreptiv enkätstudie. Enkäten innehöll främst standardiserade frågor men även några öppna frågor. Föräldrar till barn i åldrarna 0-3 år inneliggande på en barnkirurgisk vårdavdelning ombads delta i studien. Antalet insamlade enkäter var 22 stycken.Resultat: Föräldrarna var som helhet nöjda med den preoperativa informationen, majoriteten ansåg att mängden information varit lagom omfattande och att informationen från personalen oftast gavs på ett sätt så att de förstod. Några föräldrar ansåg att informationen gällande det postoperativa vårdförloppet delvis varit bristfällig.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Bakgrund: Postoperativ smärta är vanligt förekommande efter en genomgången operation. Den postoperativa smärtan kan leda till onödigt lidande för patienten. Vid en operation utsätts patienten för en större eller mindre ?skada?, där hud, muskler, leder och nerver skadas. Under den postoperativa fasen observeras patienten på olika smärttecken.

Studiens syfte var att beskriva hur människor upplever att genomgå en operation på en dagkirurgisk enhet. Detta för att fånga deras upplevelser av bemötande, eventuella oro och problem under och efter operationen. För att få en övergripande blid gjordes en litteraturstudie. Från denna så formulerades 11 huvudfrågor som stod till grund för en enkät. Enkäten konstruerades efter liknande enkäter som mall.

In this thesis we focus on the issue of master suppression techniques and how they take form on Facebook. The research in area of master suppression techniques online is limited and therefore the purpose of this thesis is to create a greater understanding of the online environment of Facebook. We have used a method of netnographic observation studies and content analysis to create a triangular perspective of the subject. Based on the result of our observation studies we draw the conclusion that you can see signs of some of the master suppression techniques on Facebook. We also argue why others don?t show up.
