Att bara slänga ihop ett användargränssnitt är inte särskilt svårt. Det svåra ligger i att göra det på ett sådant sätt att användaren känner tillförlitlighet och förtroende för det. Genom att titta på teorier om hur vi uppfattar och tar till oss information och hur information kan anpassas för att nå ut till målgruppen, kan man få fram ett gränssnitt som uppfyller några kvalitativa komponenter som utgör användbarhet; learnability, efficiency, memorability, errors och satisfaction. Informationsdesign ger oss verktygen för att uppfylla dessa krav. Att formge efter gestaltlagar, organisera med tydlig struktur och genomarbetad taxonomi med tydliga etiketter, skriva tydliga trovärdiga och språkanpassade texter och minimera bruset genom att ta bort överflödig information bidrar till god informationsdesign.

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.

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback.

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

Sisyla is a joint project between the counties of Skåne, Blekinge, Jönköping, Kronobergand Kalmar in Sweden. A geographic database has been built with the aim to study theservice situation of the area. The main purpose of this thesis is to find a method toinvestigate the quality of the Sisyla database and to apply it. The method is adjusted tothe standard ISO 19114. The agreement between the database and reality was studied ina test sample.

There are problems with poor quality, poor scheduling and poor working climate in the Swedish construction industry. Many parts have been involved, trying to solve the problem.This spring a new planning and building-law becomes final. In this law, the requirements set on the controls are greater. Hopefully this will lead to fewer construction errors. The requirements set on the working environment have also increased, forcing consultants and contractors to focus on safe workplaces.For each project requiring a building permit, an inspection plan has to been drawn.

Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.

The purpose of this study was to investigate how the interviewed people feel about being described in portrait interviews and how exactly it matches with their own image of the interview. The main issues were: Do they recognize themselves in the published article? If they don?t, what do they think it depends on? If they had the opportunity to read the article text before publishing, to what extent were they allowed to make changes to the text? Do the interviewees trust the local papers? This report involves a qualitative study on portrait interviews from the local newspaper Barometern. The articles were selected between June and November this year. The criteria for the selection of articles were that it was to deal with a single person and there be one photograph of this person in the article as well.

The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.

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.
