In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Idre Fjäll currently has not full control of how visitors experience their site or if it has good usability. I have helped the company to do a usability test on their website to see how and where any improvements can be made on the page before the winter season 2010. I have also done a survey to investigate how users perceive Idre Fjälls website. Ten people of various ages participated in the survey. All test subjects was recorded with both audio and screen activity during the tests.

På uppdrag av Sweco Systems i Umeå har detta examensarbete utförts under våren 2013. Syftet var att undersöka huruvida något av de energiberäknings-program som används på företaget kan anses vara lämpligt vid energikartläggningar av befintliga fastigheter.Inledningsvis utfördes en energikartläggning av fastigheten Odin 12 i Umeå, som i huvudsak utgörs av gallerian MVG. Med resultaten från denna energikartläggning som grund beräknades därefter fastighetens energianvändning i två olika program ? VIP-Energy och IDA Indoor Climate and Energy.Resultaten från den inledande kartläggningen visar att fastigheten har ett lågt behov av fjärrvärme, vilket förklaras av fastighetens höga elförbrukning. Den stora användningen av el genererar stora mängder internvärme som, förutom att sänka fjärrvärmebehovet, även medför att fastigheten under hela året har ett kylbehov.Utvärderingen av de två beräkningsprogrammen visar att VIP-Energy är ett lämpligt program att använda vid energikartläggningar.

The purpose of this study is to explore students? perceptions and experiences of the school-subject Swedish. Ten qualitative interviews with students in school year nine have been carried out and the results of these interviews constitute the basis of this study. The result shows that students have a straight-forward attitude towards Swedish as a school-subject. The students identify skills such as reading, writing and speaking, and work in school mainly concerns perfecting these skills. The students think of Swedish as a subject with a clear purpose and find it important and useful. The result also shows that the students want grading for the purpose of further motivation.

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.

During adolescence the teenager tries to become an independent individual, something that for many individuals can be experienced as"a hard time". In early childhood the individual was closely connected to the parents, but during adolescence friends and new contacts become more important. Studies in developmental psychology have most often adopted a parent-perspective, which is why a child-perspective is required. The aim of this study is therefore to measure the teenager's relationship with parents and friends and to look for possible correlations between these. As a means of measuring quality in the relationships, the IPPA, the Inventory of Parent and Peer Attachment, was used.

The parent-student-teacher conference presumes school responsibility of the development of the student. Teacher, student and parents are supposed to talk freely and in confidence, the conference should lead to a forward looking and long term plan. The parent-student-teacher conference should presume equality amongst the parties. The intention of this paper is to illuminate how the conference can be a way to clarify the process of learning. I intend to do this by showing the practice of four teachers, by making conclusions from their experiences they have made in their practice.

The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

In this essay I have studied how the kid?s school start are described in picture books. The studied questions are: How the school is described in these selected picture books; what feeling does the main character have into the school start; how the teachers are described in this selected picture books and how are the power relationship described in these selected picture books?The method I have chosen for this essay is a discourse analysis of seven selected picture books with the meaning of starting school. All books studied are written during the 1990 and forward.

Bronze Age cairns have been interpreted as everything from navigation marks to marking liminal places in the landscape. It has also been stated that the main purpose of their location is to be visible. This is something that has been taken for granted. The main problem is the cairns have been considered as a homogenous monument. With the help of digital methods like GIS it is possible to test this kind of questions in quantitative way.

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care.

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.

The author has, with the help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a construction safe against moisture problems. Ventilation, AC and the choice of materials have in a later stage of the thesis been investigated to enhance the knowledge of moisture protection. The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.

In Sweden, selection for leanness in pigs has been going on for almost a century. This sometimes results in gilts and sows being too lean and consequently in a risk for reduced reproduction and health status. The Swedish recommendation includes that gilts should be mated after seven months of age, after one documented oestrus, at 120-140kg live weight and with a backfat thickness of 16-20mm. Five gilt producing herds were visited and records of age, heart girth (for weight estimation), body condition (visual estimation), backfat thickness and exterior were made. The same records were also taken in four gilt buying herds on newly purchased gilts.
