In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander?s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

Jönköping Small Animal Hospital is today the only clinic in Sweden to offer radiation therapy as a treatment of tumours. The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.

This study examines how formal mathematics can be taught in the Swedishsecondary school with its new curriculum for mathematics. The study examineswhat a teaching material in formal mathematics corresponding to the initialcontent of the course Mathematics 1c could look like, and whether formalmathematics can be taught to high school students.The survey was conducted with second year students from the science programme.The majority of these students studied the course Mathematics D.The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented withformal mathematics. This both in terms of requirements for content and studentsbeing able to comprehend this content. The curriculum also requires thatthis type of mathematics is introduced in the course Mathematics 1c.The results also show that students are open towards and want more formalmathematics in their ordinary education. They initially felt it was strangebecause they had never encountered this type of mathematics before, but somestudents found the formal mathematics to be easier than the mathematicsordinarily presented in class.The study finds no reason to postpone the meeting with the formal mathematicsto university level.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

This master thesis is about designing and dimensioning a boat for transport of caravan, car, trailer or ATV. Buoyancy and stability are important properties as the pontoonboat should also be able to serve as a workboat. Many of the vessels on the market today that is being used for similar purpose are stable enough, but their hull is often similar with barges and thus too slow. This work has been to construct a boat that has good stability but also has a hull that enables it to move faster, is more maneuverable and having a more attracting design than today?s barges.

It is increasingly important for cities to attract visitors, potential new residents and businesses. Jönköping is one of the cities working with place marketing, a strategy that intends to mediate a positive image of the city, in order to accomplish just that.People often have a need to preserve the memory of a trip into something tangible. Anyone visiting Jönköping encounters a souvenir choice, much like the one in many other cities. Linked to the idea of positive place marketing, our work aims to investigate how we as product developers can create a product that en¬hances the image of Jönköping based on the thought that all residents are con¬sig¬nors. Accordingly, we develop three different products from the residents' own image of the city.Our research questions are:Based on the photographs, what image of Jönköping do the ambassadors mediate of their own city?As designers, what in Jönköping's history versus the image of Jönköping today, can we seize in order to give products for visitors a sense of authenticity?As designers, how can we use knowledge of place branding in the development of souvenirs?We performed interviews within three different aspects: history, souvenirs and place branding, all focused on the city of Jönköping.

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.

Today it is not unusual to use a secondary screen to accompany a primary screen. The possibility to integrate these two in the form of an application for the secondary screen have long been possible but have not been developed to full potential. This thesis aims to study the use of the extra information and functions this type of application would make possible and how this type of application could be used.For this study a prototype-application including a real time newsfeed and a static menu for a specific episode of a Tv-series was created based on the information collected in an online survey. The application was tested on a number of people who got to evaluate the experience in short interviews and were given the possibility to recommend changes in the application.The result after the study showed the people where torn about what kind of information would best fit the application but showed over all that a dynamic newsfeed with information continuously updated with the episode where most appreciated. The problem with the difference in interest around the categories would be solved first and foremost by the application being configurable so that every single user has the possibility to choose which kind of information to be updated in the newsfeed.

Semantic feature analysis (SFA) is a treatment technique used foraphasic word finding difficulties after stroke. The method has earlier beenevaluated with positive outcome regarding words that have been trainedduring intervention while more varied results have been presented regardinguntrained words. The aim of this study was therefore to evaluate the effectsof the method on naming in untrained nouns and verbs, in both confrontationnaming and in discourse. The present study is the first to evaluate SFA withSwedish-speaking persons. A single-subject design was used.

Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

Syftet med denna uppsats är att analysera debatten som tog plats på hemsida Newsmill åren 2010och 2012 om intelligent design. Fokusen i själva textanalysen är en argumentationsanalys somtillsammans med kritisk diskursanalys skall utröna och förstå den maktförskjutning som går attfinna inom diskursen. Den kritiska diskursanalysen är byggd på Norman Fairclough. Analysen ärordnad kronologiskt och innefattar tjugotre artiklar allt som allt.Fokus i själva analysen ligger i att utröna och förstå hur debattörerna ställer sig till religion ochvetenskap i deras argumentation kring intelligent design. Här går att finna hur religion ofta förs insom begrepp i relation till personers emotionella agerande och överlag blir religion en belastning fördebattörerna.

This thesis deals with an iterative user-centered IT-development project in a bank setting. The aim is to present a solution for deployment of future Internet banking for small businesses. The project features a design of IT-related concepts and ideas with a strong emphasis on scenario-based design and the usage of patterns as a documentation tool.The project plan featured an iterative framework and was carried out by a group of designers in collaboration with a reference group representing the future users of the system. This group consisted of company managers and bank employees, all from the small town of Åtvidaberg in Sweden.The method used in the development process was Scrum. A total of three sprints were completed with user meetings at the end of every sprint.

This study examines the use of building modeling and energy simulations in the design process  of  a  building.  The  take-off  point  is  the  notion  of  energy  simulations  being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines,  such  as  the  architect  and  the  energy  specialist,  would  create  smoother workflows, which would reduce this cost and open up for more frequent and iterative energy  simulation  processes.  The  study  is  an  assessment  of  the  modeling  tool  Revit and  the  simulation  tool  Virtual  Environment  and  whether  they  can  create  smoother workflows, and make leeway for a more frequent use of energy simulations throughout the  design  process.  It  also  investigates  the  limitations  of  what  can  be  examined  by simulations in Virtual Environment. This will hopefully help clarify the future role of energy  simulations  in  design  processes.  The  method  is  a  trial  by  error  approach  of testing the two software tools by building and simulating a model. The results of these tests  show  that  the  workflow  is  not  optimal  (and  therefore  time  consuming)  for frequent  and  iterative simulations  throughout the  design  process,  but  it  also  reveals some  great  possibilities  of  what  can  be  performed  with  these  two  powerful  tools  at hand.  Further  development  with  regards  on  platform  independency  of  the  building information  model,  including  seamless  exporting  and  importing,  seems  necessary  to strengthen the future role of energy simulations..
