This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

This thesis has been performed for the company System Andersson as a part of the bachelors degree in information technology at the School of Engineering in Jönköping. The thesis is based on the development of an iPhone application.System Andersson has an application for Android that is being used for their MPS system (material and production control system). Their customers, however, have also showed interest in being able to use this application for iPhone.The students handle the subject of iOS developing, including the design of the application, the use of the development language Objective-C, the use of the scripting language of Json used for server connections and SQL.The primary goal with this thesis has been to improve the students knowledge in such subjects as application development for mobile platforms, in such areas as Xcode, which is the development platform that Apple uses and Objective-C, which is the development language being used. The result of this thesis is an almost fully functional iOS application, similar to the Android application with some functionality missing..

This essay will try to analyze how Syria?s official news agency, SANA, describes events taking place in Syria in the days between 1.4 and 18.4.2012. This will be contrasted with how BBC and CNN describe the events. These other two news agencies were chosen, because they represent media from democratic countries in Europe and the USA. This rebellion became a full scale civil war over time.

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.

Finns det ett samband mellan den individuella självkänslan och den kollektiva självkänslan? Har kön och studieinriktning betydelse för självkänsla, såväl som den individuella som den kollektiva? Studien är gjord som en kvantitativ undersökning med hjälp av enkäter, bestående av Som Jag Ser Mig Själv (Irhammar & Birgerstam) som mäter självkänsla på individnivå med fem delskalor, och Collective Self Esteem Scale (Luhtanen & Crocker) som mäter den kollektiva självkänslan med fyra delskalor. Det ena testet innehöll 67 frågor, medan det andra innehöll 16 frågor. Totalt deltog 60 försökspersoner hämtade från ett gymnasium i Kristianstad, och dessa var i sin tur uppdelade i två samhällsklasser med olika inriktningar ? IT och Ekonomi.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

This essay is an attempt to portray and explain my work as a dance pedagogue as well as an epistemological overview of the skills and knowledge I use when I teach. The study is phenomenologically oriented and the examples used are from the years when I was teaching at the University College of Dance in Stockholm. The primary objective of the study was to illustrate the practical knowledge of my teaching by examining what lies in the mind and gaze of the dance pedagogue while teaching.Having finished my essay I realize that it has come to be primarily about the body. How the knowledge that is imprinted in my body can only be conveyed when I have a student to teach and how I feel that the intermediary of knowledge occurs. Other recurrent themes are the relations of thought and consciousness to the body.

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.

Människors allmänna välbefinnande och livskvalitet påverkas av deras sömn.    Sömnproblemen ökar och resulterar i ökade kostnader för den enskilde, arbetsgivarna och samhället. Syftet med litteraturstudien var att beskriva effekter av sömnhygieniska åtgärder riktade till individer inom hälsovården med primär insomni. Resultatet visade att en kombination av åtgärder utifrån personliga behov gav bäst resultat men också att det rådde begreppsförvirring runt sömnhygieniska åtgärder och deras effektivitet. Fördjupad kunskap behövs vad det gäller de enskilda sömnhygieniska rådens effektivitet.

I en delstudie till IDA-projektet har 185 kvinnor i 40-årsåldern skattat sin stress med PSS (Perceived Stress Scale) och genomfört fyra episodiska minnestest. Ett omvänt U-format samband med PSS som oberoende faktor och prestation i de olika minnestesterna som beroende faktor har prövats. Ett linjärt samband har sökts post hoc. Både explicit och implicit minnesprestation har mätts, liksom primär- och sekundärminnesprestation. Hög- och lågutbildade deltagare analyserades separat.

Today many children and youths are allocated to ?The Swedish Authority of Child and Youth Psychiatry (BUP) for the sake of being investigated by means of a neuropsychiatric inquire and many of which are assigned the diagnosis ADHD. During recent years ?The Swedish National Board of Health and Welfare? has declared, in it?s annual account of the current psychiatric state of Swedish Children and Youths, that the healthcare provided for those with neuropsychiatric diagnoses ? such as Asperger syndrome and ADHD, has increased.ADHD is short for Attention deficit hyperactivity disorder, which implies neuropsychiatric impediments i.e. hyper activity, inadvertence and an inability to control impulses.The aim of the Study is to describe and analyze how youth, in the age range of sixteen to eighteen years of age, diagnosed with ADHD define themselves, their daily life, their social state, their next to kin relationships and, finally, their concept of their future.The Study is qualitative.

The aim of the work was to gather information on parents' reflections on their own need for parental support in their role as parents. Where a need was expressed we investigated what form of support was desired and who should provided it. We also wished to find out if there were any differences or similarities in the needs and wishes expressed by the parents.The questions posed were: Did the parents feel that they needed support in their roles as parents? If so, what sort of support did they want? Who should provide this support? What differences or similarities were expressed in the parents needs and wishes for support?A questionnaire study was carried out within Landskrona. The results showed that a majority of parents expressed a limited need for some form of support in their parental role.
