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.

The characteristics of free movement is the elimination of obstacles to trade between Member States and thus by such, create free movement within the entire union. Therefore art 34 in the Treaty of Lisabon (FEUF) states that all quantative restrictions on imports and measures of equivalent effect are prohibited. The legal approach to measures having equivalent effect is still unclear and the purpose of this paper is therefore to propose a solution to that particular problem. What can be said when it comes to this rule is that the EU-Court has gone from applying a discrimination test to a market access doctrine.According to the Court´s case law, measures having equivalent effects to quantative restrictions are ?All trading rules enacted by Member States which are capable of hindering, directly or indirectly, actually or potentially, intra-community trade?.  The question of how to apply the test when it comes to a potential hinder to intra-community trade is still unclear.

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Our purpose with this research has been to obtain a deeper insight and understanding for the phenomenon and term ?weekday-luxury.?Through our research, we have found a link between value, service, brands and consumer behaviour into a relationship that we termed ?weekday-luxury.? This link of values is particularly interesting to us and we are curious about the underlying motivation to ?weekday-luxury? and the driving forces underlying the phenomenon. We have noticed in society that people need something extra in their daily lives and we attempt to speculate where their perceived value lies through the concept of ?weekday-luxury." Our goal is to determine a deeper understanding and insight into this phenomenon and how it meets our needs through an identifiable pattern. We also analyze the nature of ?weekday-luxury? and its meaning.

The aim of this study is to investigate the effect of an intervention that focuses on phonics, decoding, reading speed and phonological awareness for 8-9 year old children in reading difficulties. Participants were selected on the basis of screening test results in grade one (decoding and reading comprehension). The participants were divided into two groups, an intervention group (A1, n=10 children) and a control group (A2, n=10). A1 received 30 minutes of intense reading instruction every day for six weeks from special educational needs teachers on top of their usual classroom based reading instruction. The control group received only their usual classroom-based reading instruction.

In Sweden the amount of people with obesity has increased with almost 50 % during the past 20 years and is now including 500 000 people. A larger energy intake than energy consumption is today one of the most important cause of overweight and obesity that exist in the world. This requires more knowledge about healthier eating habits combined with moderate intensive exercise, exercise that is simple, effective and amusing. A god solution is a combination of fitness training and strength training, a type of circuit training. It is distinguished by a high intensive work in short periods and with a short break.

Introduktion: HIV-infektion medför en kronisk och progressiv sjukdom som, i obehandlad form, leder till en successiv försämring av immunförsvaret och utvecklandet av AIDS.Syfte: Att vid två lärosäten undersöka sjuksköterskestudenters kunskaper om HIV och inställningen till behovet av HIV-testning.Metod: En empirisk tvärsnittsstudie med deskriptiv och komparativ design med kvantitativ ansats. Genomförd som enkätstudie bland studenter vid Högskolan i Gävle och Uppsala Universitet (N=95), som studerade på sjuksköterskeprogrammets tredje år. Resultat: Majoriteten (88,4 %) angav korrekt att samlag med fler än en partner ökar risken att smittas med HIV. Tre studenter (3,2 %) angav felaktigt att det finns ett vaccin mot HIV-infektion. Nästan hälften (42,1 %) saknade kunskap om att glidmedel, tillsammans med kondom, inte minskar risken för HIV-smitta.

Due to the decrease in obtaining driver?s licenses among young people, the main purpose of this study was to acquire a deeper understanding of young people?s attitudes towards driver?s license and towards driver?s education. This is a qualitative study with a theoretical approach, which combines Bourdieu with post modern theories. By using focus groups a wide rage of attitudes among young people have been gathered. Having a driver?s license is still considered a standard among young people even though their attitude mostly depends on their need for one.

Syftet med denna studie var att ta reda på om STAVUX (stavningstest för vuxna) och Kasttranskription är lämpliga test att använda vid dyslexiutredningar av vuxna, då det idag saknas sådana test som är normerade på personer över 18 år. STAVUX är ett stavningstest som framtogs av Nilsson och Pettersson (2009) och som består av 45 ord och 45 nonord av varierande svårighetsgrad. Orden är utvalda för att representera svenskans olika stavningskombinationer och nonorden är konstruerade för att följa svenskans ljudmässiga uppbyggnad. En mellangruppsdesign användes för att ta reda på om STAVUX är ett lämpligt test att använda vid utredning av stavningssvårigheter i samband med dyslexiutredningar. Testet validerades på 23 personer med dyslexi i åldrarna 18-64 år.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

Trots att självkänsla är ett frekvent studerat ämne saknas en allmänt erkänd teori och definition som kan utgöra en grund då självkänsla studeras. Gemensamt för flertalet teorier är att självkänslan grundläggs i barndomen samt att självkänsla rör en persons uppfattning om sig själv och personens omdöme om hur han eller hon uppfattas av omvärlden. Studiens syfte var att göra en psykometrisk utvärdering av en modifierad version av Jag tycker jag är samt att studera formulärets test-retest reliabilitet. Jag tycker jag är utvärderades genom att analyseras tillsammans med andra välprövade självkänsloskalor. Undersökningsdeltagare var 100 psykologistuderande (M = 28.4 år; s = 7.3 år).

This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.
