Warnit AB har under ett tidigare examensarbete vid LTU utvecklat ett intelligent larmsystem som känner av vibrationer och automatiskt sänder ett trådlöst larm till användaren via SMS eller e-post. För att utveckla ytterligare produkten har Warnits VD, Peter Stenlund kommit med ett förslag om effektmätning på trefassystem. Detta examensarbete har i samarbete med EISLAB (Embedded Internet System Laboratory) vid Luleå tekniska universitet resulterat i ett prototypeffektmätningssystem för aktiv, reaktiv och skenbar-effekt på symmetriska trefaslaster. Aktiv, reaktiv och skenbareffekt kan avläsas både på plats via en display och via Internet på en webbsida genom att använda WarnitBoxens trådlösa kommunikationsmöjlighet för att koppla den trådlöst till Internet..

In order to fully grasp the phenomena 'City' we must understand its political structure as an integrated part of its physical structure and vice versa. This thesis focuses on one crucial element of the City, the public space, and discusses it in relation to the public realm, or sphere, of the City. The aim is to see if it is possible to conceive public space as a spatial dimension of power, and if so, how to analyse this. With the help of the theoretical tool of two ideal types of the configuration of public space, "The city as civic public life" and "The city as authoritarian control" an empirical study is carried out on the case of Prishtina, capital of Kosovo.Conclusions made are that function and use of a city's public spaces can be understood in relation to changes in the political climate of the society. Furthermore, a void in the asset of concepts offered by the ideal types is found ? and therefore also need for new concepts to describe and understand a public space undergoing a dynamic transformation, as being a part of a city in political transition..

For centuries, springs have played a significant role in our society as water supplies, reasons for where to settle down, and in folklore. There are different reasons why and where a spring forms, e.g. in what kind of soil it has its outflow. Geographic and geochemical surroundings have an influence on spring-water quality.For this project some of the springs in the Lagga perish, Knivsta municipality, Sweden, were selected for a closer study. Water samples were collected from springs for analysis.

This essay deals with a picture-stone that was found in a pre Christian grave during the archaeological excavations of the Viking Age harbour and trading place at Fröjel parish, Gotland, in 1999. The stone is at least 100 years older then the male grave in which it was found. The picture-stone can be dated to  late 8th century or early 9th century, and the grave is probably from the late 10th century. One of the main questions in this essay is why the people of that time re-used an older picture-stone in a younger burial. I believe that the stone was reused as a grave-gift.

Syftet med studien är att presentera olika begrepp med definitioner för odefinierade rum i bebyggd miljö. Rum som blivit över eller bortglömda i stadsplanering, övergivna och förfallna områden eller rum som saknar en känsla av identitet. Olika författare med olika bakgrund presenterar olika begrepp och definitioner för dessa rum. Genom litteraturstudier undersöks nio relevanta begrepp från publicerad litteratur. De undersöks utifrån frågor som behandlar författarens ursprung, verkets publiceringsår, begreppets definition, exempel som ges på odefinierade rum, hur rummen uppkommit samt hur de enligt författaren bör behandlas i planering.

Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..

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.

The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural Science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.

The aim of this study was to investigate the leaving care services provided to youth leaving residential care in Sweden. Through the use of qualitative research interviews residential care workers perception of what practical and emotional needs youth leaving care have, and whether current aftercare services meet these needs, were examined. The study further sought to compare the swedish and english leaving care services. The main findings of the study were that the residential care workers interviewed expressed that they had a good working relationship with the local social services and that they through the residential care services were able to provide some degree of aftercare. They further identified loneliness as the most prominent emotional need of youth had after leaving care.

This paper presents an analysis of history textbooks used in schools in Sweden and Norway. The intention of the research was to study how the history textbooks describe communism and communistic dictatorship mainly during the cold war. The result of this study is that there were no big differences between Swedish and Norwegian history textbooks, but there are, however, some differences in how communism was described between the authors and also over time. Mostly, the books that were written in the post cold war period were somewhat more critical to communism in the eastern Europe (even thought they mainly handled with Stalin´s communism. And they also set quotationmark between Stalin´s communism and the nazi terror during World War two..

As technology have continued to develop over the latest decades and become more advanced the pressure on the general citizens understanding of technology becomes a essential part to live in our society today. The transition have affected our society in great ways and have made a great impact on different groups, one of them being the elderly population in our society. The purpose of this study is to examine how the fast technological development in the latest decades have affected the elderly in our society. This from their perspective by gathering empirical data through semi-structured interviews with elderly people involved in the Agnes-project, a research project focused on improving the general quality of life for older people and increase their knowledge about technology. The study has shown that after the older peoples time involved in the Agnes-project their quality of life had improved in different areas. Areas such as increased cognitive activity, increased interest in new technology and an improvement in their communication with friends and family.

Syftet med studien är att skapa en förståelse för hur en byråkratisk organisation arbetar för att på en och samma gång vara såväl regelstyrd som deltagaranpassad samt hur detta påverkar individerna som deltar i verksamheten.För att uppnå syftet har det utgåtts från följande frågeställningar:  Hur upplever deltagarna samarbetet med konsulten?Hur ser Arbetslivsresurs metod för arbetet med deltagare i omställningsuppdrag ut?På vilket sätt individanpassar konsulten mötet med deltagarna? För att uppnå syftet har kvalitativ metod tillämpats. En intervju har genomförts med en konsult på Arbetslivsresurs som bland annat arbetar med omställningsuppdrag samt har intervjuer utförts med åtta deltagare som medverkat i omställningsuppdrag i anslutning till Arbetslivsresurs. Resultatet visade att konsulten i samtalet med deltagarna använder en arbetsmetod som utgår från individen. Vidare visade resultatet att samarbetet medfört positiva upplevelser för deltagarna samt upplevde deltagarna ett individanpassat bemötande i stor utsträckning. .

At present, the Swedish pig industry is in transition. Prices have been low, but feed prices have increased. Therefore, many pig producers have stopped their production. Producers that lack an integrated production may contract piglet?s producers, or may use the mediation services that slaughterhouses provide.

Sjuksköterskeyrket är ett mångdimensionellt och komplext yrke. Utbildningen och inskolningsperioden ska förbereda sjuksköterskan inför mötet med den nya rollen, dock upplever nyutexaminerade sjuksköterskor sig sällan förberedda inför den nya yrkesrollen. Svårigheter uppstår därmed under transitionen. Syftet med litteraturstudien var att belysa hur nyutexaminerade sjuksköterskor upplever yrkesrollen och transitionen från student till sjuksköterska de första sex månaderna i yrket. Litteraturstudien baserades på fjorton vetenskapliga artiklar som granskades och analyserades.

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.
