Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.

The purpose of this essay has been to investigate if the national test results, in the subject of Swedish B at upper secondary school, are affecting a student?s final grade in varied degree among different teachers. The purpose has also been to investigate if the assessment of these tests is equivalent among different teachers. This particular investigation showed that there are big differences between how teachers grade, in relation to achieved results on the national test. According to the Swedish National Agency for Education, the teacher should take all performance information available into consideration for each particular student.

Aim: The aim of this study was to examine and explain the various methods available to rate the erosion damage, and on which teeth and tooth surfaces of erosion damage mostly occurs in children and adolescents.Method: A literature review was conducted, based on 15 scientific articles that have been reviewed, evaluated and analyzed. Articles were searched for in the database PubMed.Result: Six of the articles used the TWI (tooth wear index), which is an index to diagnose the tooth wear in the primary and permanent dentition. Eight articles used other indices as they considered that the TWI was not sufficiently developed to register the degree of tooth wear on some teeth. Tooth wear in the primary dentition occurs most often in the canines and incisors. Tooth wear in the permanent dentition was found in the literature to be mostly occurring on the occlusal / incisal surfaces of all teeth and tooth surfaces.LyssnaConclusion: There is no common index in the articles but many of them use the TWI.

Background:Alzheimer's disease is a disease that primarily affects the elderly but also younger people. Alzheimer's disease is a type of dementia which means that you get changes in the cerebral cortex and cells gradually die. The disease causes memory loss and things that were obvious before will be difficult for the sufferer. Alzheimer's disease also affects next of kin to a large degree; they will have to take a great responsibility. The next of kin are entitled to support from healthcare.Aim:The aim was to highlight next of kin' experiences of healthcare to their family members with Alzheimer's disease.Method: The study was based on narratives, which in this case means analysis of autobiographies.

According to many scholars America's soft power is in decline, a power resource whose importance has been increasing in world politics. This makes it interesting to examine if there is a difference between how Democratic and Republican administrations wield their soft power.This thesis is a hypothesis-testing study and the purpose is to test the hypothesis that Democratic administrations, to a greater extent than Republican, can create, utilize and defend soft power. My thesis is based on Joseph Nye's theory of soft power and the focus of this study is the aspects of the foreign policy resources. In order to measure this concept I have made my own operationalization where five different indicators serve as my guidance. I use the method of least likely-cases to select and motivate the administrations being tested, which gives me a comparative study of the Democratic administrations of Lyndon Johnson and Bill Clinton and the Republican administration of George H.

Companies within the e-commerce industry currently try to overcome the disadvantages of not being able to provide a physical inspection of products, and this is especially an issue for the apparel industry. One way of trying to overcome this issue is by presenting apparel with a short video of a model wearing the garment. The aim in this thesis is to investigate how these video presentations affect consumers' emotions, cognitions and intentions. Since previous studies have found that different shopping scenarios can moderate the effect of stimuli in the atmosphere on the consumers' emotions, we also aim to see if a video presentation, depending on the shopping scenario, could have a negative impact on site visitors. Moreover this thesis investigates the moderating effects of involvement on consumers' cognitions.

For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

This master's thesis reports on our investigation of how the public librarian's professional identity is formed and what it is formed of. We have considered factors such as: education, competence and daily tasks. In order to fulfil this aim we have used a literature study on concepts such as competence, education, professional identity and profession. We have also carried out an empirical study where we have interviewed nine librarians on public libraries. The method of analysis is qualitative.

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment.I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power.I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level..

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

SummaryI have a great interest in bouzoukis and since I, during my education in guitar making, mainly have focused on building bouzoukis and other traditional folk instruments, I have chosen the bouzouki as the object of my degree project.In connection to the making of these instruments, I started to consider the construction of the bouzouki and why the bouzouki has such a characteristic sound.One of my theories is based on the fact that most bouzoukis are made with floating bridges instead of glued pinbridges. Do these types of bridges differ from each other tonally and if so, how much and in what way?To receive answers to my questions, I have built two identical bouzoukis with different types of bridges, one with a glued pinbridge and one with a floating bridge. I have been very precise in the making of these instruments, giving them the exact same dimensions and using material from the same piece of wood. This to make sure that the instruments should be as exactly alike as possible.After finishing the making of the bouzoukis, I arranged for a sound test where I let musicians play and listen to the instruments.

Lately, alarming reports have appeared regarding the work environment and work situation of social workers. Research focusing on the promotion of health and well-being in the workplace among other professionals show that factors such as social relationships, ability to influence their work situation and leadership are important. A quantitative study was conducted focusing on the work climate for social workers employed by some of the district administrations in the City of Malmö. A questionnaire with questions and statements on various factors in the work environment was sent to 34 social workers. They were asked how important these factors were for their well-being, as well as to what extent they felt that these factors were present at work.

The structure of the Swedish public library field has been evolving during the last decades. The traditional mission of educating the citizens to become responsible, democratic and knowledgeable members of society has in a way led to the integration between public and school libraries. Lately new co-operational models have been under debate and a sense of resistance has arisen because of the economical and market influences. In parallel with closure of library branches new libraries have evolved in malls and wash houses and some with self-service with no use of librarians. This work shows how co-operation in rural areas finds the common goals for the people living there who are concerned about keeping the service needed including the public library and thus using existing means and crossing borders of commercial thinking.

Studies among parents of children with disabilities have shown that they experience a higher level of parenting stress as well as a lower degree of wellbeing, compared to parents of children without disabilities. However, there is a need to further explore parents? experience on this matter within a Swedish context. The aim of the current study was to examine how parents of preschool children, with and without disabilities, in Västerbotten, experience the impact of their child. A sample of 67 parents of children with disabilities and 134 parents of children without disabilities took part in the questionnaire study.
