Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Cancer is one of the most common diseases and it affects not only adults but also many adolecents and children every year. Those who are affected of disease face many challenges that will affect their lives. The aim of this literature review was to illuminate adolecents experience of cancer and how it affects them in their daily living. The result showed that the adolecents experience many physical and mental side-effects from disease and treatment. They expressed the need of information, support and understanding from their families, friends, school and care givers.

The present work is a continuation of the ideas developed in previous projects during my Masters studies that explored the relation between pattern, form and space. Starting from the pattern multiplication for space construction the present project proposes textiles as an assortment of flexible expressions. The purpose of the project is to explore aesthetic and functional potential of textiles for out door temporary structures. This is to create a pattern interface which filters sunlight through a textile surface to offer instant sheltering solutions for out door activities. The project combines research and analyses of outdoor temporary structures and scope of textile in the area.

This is a qualitative study of how 4 school teachers and 3 special educational teachers define the term ?pupil in need of special education?. They have each one been interviewed about this term, by the means of a semi-structured interview. Afterwards the collected information has been analyzed and seven major themes have been arranged out of them. From these themes it is possible to see that the term is hard to define, since the participants all believe that it should be decided by each individual case, if the pupil is in need of special education or not, and that the education in itself has to be relevant to the need, which means one cannot decide what special educational needs are, without a student who is in need of them.

The Promised land ? A letter analysis of America letters from 1850-1870 This essay is about the Swedish emigration to America. This essay will focus on the period 1840-1870, where the main focus will be the american civil war, and what the immigrants wrote back to their relatives in Sweden. This study will also focus on the integration of Swedish immigrants.My main question are what did the swedes write back to Sweden during the war? And how did it differ from the period before and after the war?But also can a war assimilate a immigrant faster than it would be done without the war?The conclusion that has been made is that the war did help the swedish immigrants to integrate much faster than usually.

Establishment can be described in many terms. This term is about a company that is establishing on the European market. For many companies, this can appear as a difficult, time- and resource taking process but to advance and develop it is not enough to have a good position on the Swedish market. The company Akzo Nobel Nippon Paint AB, which this composition is about, has taken the risk to leave the home country and explore the unknown. The process was careful and long-termed but also profitable.

The following paper looks into MaternityPaternity leave and how the parents make use of it. The underlying reasons for the paper, is a pattern of unequal division of leave between the mother and father.By using a qualitative in depth interview technique with couples that have children between 2 and 3 years old we have looked for reasons why the decisions, around the division of leave, have been taken, and what factors influence the outcome.We have found that great importance is attached to, how, the negotiations are carried out between the parents, although these negotiations are influenced by a series of circumstances where the families economic situation influenced by the employment market are important factors.The results from the empiric part of the study showed a link between the childs age and which parent stayed home. Furthermore, the results show the families place in relationship to the structure of society also plays an important part in the concluding division of leave..

This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.

Most of the people in today's society have at least some knowledge about Alzheimer's disease to some extent. When a person with Alzheimer's disease is being taken care of at home, the relatives have to change their own priorities and readapt themselves to the existing situation. The primary aim of this study is to describe how the relatives experience their own situation in life. The secondary aim of this study is to describe how the relatives understand their own relation with the health care authorities concerning the help and support issues. The authors have realized this study using the analytic inductive method and have interviewed four informants using a semi structured interview guide.

The aim of this study is to examine the opinion of teachers as to the situation of young people suffering from Aspergers syndrome in the Sixth Form(gymnasium. In order to find this out I have chosen to interview four teachers with work experience of Aspergers in three different gymnasium in middle Sweden. They were confronted with the following questions: What resources are available for these pupils in the gymnasium? How do they experience that the school situation functions and how would they as teachers like the school situation to function for these young people at school?The result shows that special teachers have an extremely important function to fulfil. Those interviewed felt that there are sufficient resources available, for example guidance and further education for techers as well as both support and means for helping the young people.However, every teacher does not understand this handicap.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Instagram is one of the most common used social media platforms among teenagers today. It is not only one of the most common used social media platforms, but as well one of the most common places where cyber bullying takes action. By using focus groups, netnographic studies and a questionnary we investigate the meaning of technology regarding how the bullying on Instagram takes shape and the strategies used by teenagers to handle cyber bullying.Our research shows five different ways that cyber bullying takes shape and ten different strategies implemented to handle those. The findings are compared with previous research. The ten different strategies are then discussed from aspects that are found to have a big influence on how those are implemented: gender, knowledge, experience and awareness, presence of parents and other relatives, personal experience, trust in the technical solutions and the weaknesses of those. .

The essay describes the bachelor project by Marie Hanås, in collaboration with Skälsö Arkitekter. Skälsö Arkitekter are currently developing an area in the north of Gotland, Bungenäs; previously home to lime stone quarries and military bases.The brief was to design a set of outdoor furniture to complement the new development. The main effort of the project was in designing furniture that would fit the environment visually but construction issues were a major secondary concern, to ensure the easiest possible manufacturing. A reference group of coastal house owners were interviewed, and their feedback, together with an analysis of functions, trends and target groups, were the base for the ideas.Of the five concepts presented, Skälsö Arkitekter chose one to develop further. This was done through sketches, models and 3D models and led to the final result which is lightweight furniture of Gotlandic pine wood with an industrial touch.

I Sverige är det en kvinna på tusen som väljer planerad hemförlossning. Med planerad hemförlossning menas en förlossning som planeras ske i det födande parets hem med stöd av en legitimerad barnmorska eller läkare. Då hemförlossning idag inte ingår i det svenska hälsovårdssystemet får kvinnan själv se till att ordna ett avtal med barnmorska eller läkare och även bekosta vården själv. Det finns forskning om hemförlossning i relation till medicinsk säkerhet och kvinnors upplevelser. Vidare finns ett fåtal studier om barnmorskor som bistår vid hemförlossning dock inga från Sverige.

Den textila industrin, en egen värld, är nu under rampljuset som en av de största miljöpåverkande industrierna. Precis som i fallet med många andra industrier så måste textilbranschen intensivt arbeta med att minska sin negativa påverkan på miljön. Slutmålet måste vara att helt balansera uttagen och insättningarna så att man skapar en bransch som blir klimat- och miljöneutral. I denna rapport har en livscykelanalys gjorts på en underställströja från Helly Hansen tillverkad av 99 % polypropylene. Inom denna livscykelanalys har vi noggrant studerat och undersökt fakta för att hitta de processer som har den största påverkan på miljön.
