Despite the fast growing development of IP-telephony services, only a small number of people in Sweden use them. Of the total amount of fixed telephony subscriptions, maximally five percent are based on IP-technology. Through an exploratory study, the main purpose with this thesis is to identify factors that influence the use of IP-telephony on the consumer market, and the factors? internal relationships. The thesis also has two sub-purposes: firstly, chart the supply of IP-telephony services and secondly, discuss what IP-telephony services that are requested by today?s customers in the future.

A home for elderly is planed to be built at Zakrisdal, Karlstad, Sweden. The heat source for the building was at the time not determined. In order by the local government of Karlstad this report is meant to examine if the need of heat could be provided only by solar heat combined with a seasonal heat storage. The problem to solve is, if the need of heat from the home for elderly is provided from only solar heat, whitch dimensions of the solar collectors and the storage is needed?.

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Denna rapport är en undersökning om hur man gör en bana i ett FPS-spel så att banan blirintressant och rolig så att så många spelare som möjligt vill spela den. För att komma framtill det har jag skapat en bana i Hammer till spelet Team Fortress 2 för att göra vissa testerpå den för att därigenom komma fram till mitt resultat.Slutligen kom jag fram till att det viktigaste när man skapar en bana är variation och att hamed något som passar alla. Dessutom kan det ha en viss vikt hur banan ser ut annarskommer folk inte ens testa banan..

Det är viktigt att se hälsa ur ett helhetsperspektiv där den sociala, fysiska samt psykiska hälsan ingår. Människan tillbringar en stor del av sitt liv på arbetsplatsen, det är därför en viktig arena att arbeta hälsofrämjande med. Hälsofrämjande sjukhus är ett exempel på en sådan arena. För hälsofrämjande sjukhus är det bland annat viktigt att främja den egna personalens hälsoutveckling i en positiv riktning, med hjälp av en aktiv kunskapsförmedling. På arbetsplatsen är det viktigt med nyckelpersoner som kan förmedla kunskap om hälsans villkor till övriga anställda.

The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.

The purpose of this study has been to get a deeper insight into how students reason about the textbook and teaching that goes beyond its content. This in order for the teacher to be able to consider and respond to these important attitudes already at the planning stages of such teaching situations. This approach will aid to help students overcome the distrust of things that are not in the textbook.The study shows that students have an attitude of overconfidence to the textbook's reliability. It is considered to be controlled in its content as well as being a reference on the extent of the knowledge content.The general approach to teaching that deviates from textbook structure is that it is welcomed as an interesting feature. However, a questioning attitude soon appears about whether the element will be included in any requirements for knowledge or tests.The following important conclusions can be drawn after this study was carried out:Very clearly communicate the purpose of all education that deviate from the textbook.Inform students about the textbook's deficiencies and the need for supplementing.Accept and respond to students' focus in that grades are the main driving force for the acquisition of knowledge in high school..

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

The purpose of the study is, through literature and interview studies, to analyze and draw attention to critical mindedness regarding news features in a multilateral way. In the interview 16 participants got to see three SVT news features with lack of criticism. Great importance was given to the spontaneous reasoning of the participant. The study is explorative and has given a number of hypotheses and ideas for further research concerning the subject. Among other things the study shows that previous beliefs affect the critical mindedness of the individual, that individuals have the ability to think critically if reminded and that the trust of the source and medium affects the critical mindedness of the individual..

This thesis concerns the policy process of a proposed bill. The specific bill constitute a new penal law which is supposed to replace the old penal law from 1974.The questions asked considers what in the foregoing policy process that has proceeded, affected and also characterizes the proposed bill. In order to be able to produce a deep and reliable analysis to this question I use two different theories.The first theory being used consists of John W. Kingdons theory of ?multiple streams? which I use to answer the specific question ?what can be recognized to have proceeded and characterize the policy process that the penal law bill involve??.The second theory consists of Peter Santesson-Wilsons development of symbolic policy theories which is given a concrete form in the ?taxonomy of symbolic policy? which he presents.

The purpose with this study was to examine how persons giving care to their spouses with dementia experience their life situation. As information source we used a qualitative study which included halfstructured interview questions. The study took place in three municipalities in the south of Sweden. Three females and two males took part in the study and everyone had experiences of giving care to their spouces with dementia. We used a coping theory and an exchange theory.

Inspired by how to sketch a light cone from a flashlight in a comic I wanted to create an armature carried only by its own light cone. To manage this challenge I sketched in an architectural and sculptural way, where I chose to ignore the function of the lamp as long as possible.As a result I developed an armature with a stunning shape, with an illusion that it was carried by its own light cone. It could be hanged on a wall, placed on a table, pushed against a ceiling or standing on the floor.Depending of its size the light cone from the light source lightens up the surface and draws attention to the otherwise forgotten wallpaper or the undisposed statue in the darkness of the city..
