In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

The purpose of this study was to investigate how the special education, for children with language impairment in preschool, was organised in a municipality in Sweden. The study was based on interviews and field studies as the primary research tools in qualitative and ethnographic method. The result showed that special education teachers were localised in different geographic areas of school and that there were preschools that lacked special educational expertise in language impairment. Literature and the importance of playing for language development were emphasised as well as the use of signs and visual aids as augmentative and alternative communication. In the preschool for children with language impairment, the teachers carried their knowledge into practical and pedagogical work.

The aim of this paper is to see how the local authorities in Norrköping create a way to look at homelessness. This aim is examined with the help of the central questions: How does the municipality describe homelessness as a phenomenon? What causes to homelessness can be seen in the texts? How do they describe homeless people? And What kind of actions are used or proposed? The analysis has been done with the tools and thoughts of the critical discourse analysis and made on text documents written by politics and employees of the city of Norrköping. The theories which have been used are those of postmodernism, welfare, homelessness, civil society and relative poverty. The analysis shows that the way the municipality of Norrköping looks at homelessness correspond with the way homelessness is presented in current Swedish research.

Purpose: The purpose of the essay is; to explain and clarify how the company is acting to lead members in social media to achieve valuable external communication. The authors believe that it is important to act with credibility and quality in social media, to accomplish long lasting relationships. When employees communicate with consumers their conduct is relevant to the company's credibility.Methodology: An inductive approach has been used for the empirical data collection since the authors have been studying the reality without existing theories. A qualitative research method has been used for collecting the empirical material. Primary data was collected from telephone interviews with seven companies, active in social media.Conclusions: The study shows that the power of employees? can be used when designing strategies for social media.

The overall aim of this study is to clarify the situation in school for children with language disorder from the parents? perspective.Data were collected through five interviews with parents who have children of different ages and with various diagnosis within the language disorder spectra. A qualitative method based on a narrative inquiry was used and each interview was based on a interview guide with the following themes: the child?s difficulties, starting school, the school?s pedagogy, homework, action plans, participation and the future.Each story has its own themes, but there are also themes that are common in all interviews. One common theme in the parents? stories is that school has a lack of knowledge when it comes to language disorder.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda. Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.

Lean Production is used by many manufacturing companies. Companies in process industries do not use Lean Production to the same extent today. This is part of the report's issue to explore how Lean Production can be applied to a company in the process industries.The investigated company is a processing company that manufactures various types of foil. The company wishes to streamline its production and has therefore asked the authors to examine if Lean Production can offer the company improvements in their production. Lean Production value stream mapping tool has been selected to identify and analyze the current state of two of its products in production.

Syftet med detta arbete är att diskutera förhållandet mellan historisk spelfilm och historieundervisningen i den svenska skolan idag. Spelfilm har blivit en del av elevers vardag och historiker diskuterar i allt högre grad hur historia används i spelfilmer och hur detta påverkar vårt historiemedvetande. Möjligtvis är det så att detta bruk av historia leder till ett nytt historiemedvetande. Film kan ses som ett pedagogiskt redskap, en upplevelse som leder fram till intresse och kunskap. Vad detta arbete strävar mot är att undersöka om man kan lära sig något om det förflutna genom historisk spelfilm samt om historisk spelfilm kan utveckla elevers historiemedvetande. Arbetet tar sin utgångspunkt i ett projekt om historisk spelfilm genomfört med högstadie- och gymnasieelever på två skånska skolor. Med avstamp i visandet av två filmer om medeltiden; Robin Hood- Prince of Thieves och En riddares historia, diskuteras faktakunskap, förståelse och historiemedvetande..

According to law all Swedish authorities must express themselves using correct, plain and comprehensible language whenever they communicate with the citizens in order to make it easy to understand what needs to be known to participate in the Swedish democratic society. I would like to explore if there are more tools than the language that could be used to make their communication easier to comprehend, in this case images and stories. In this essay I will investigate the relationship between the written words and the visual components ? images and illustrations ? in brochures from Swedish authorities. I will also try to identify possible narratives in the brochures, and examine the functions of these narratives.

The aim of this undergraduate thesis was to study what the participation in the activities of the Fontain House in Stockholm means to its members. The research questions dealt with how the members describe their participation in the activities, whether they say that it has helped them, and, in that case, in which way. Furthermore, they dealt with how the members argue about their experiences of mental illness and of social help. The study was carried out within the framework of the narrative method. As tools for analyzing the narratives, parts of An-tonovsky?s theories as well as the theoretical concepts of inclusion and exclusion as described by Madsen, were used.

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.

Along with the development of technology, the cross-border trade is increasing and therefore there is a need for greater consumer protection. A good consumer protection creates a feeling of safety for the consumer and that by itself may help to increase cross-border trade. This is one of the reasons for why the EU has established regulatory framework for electronic commerce, for example the Directive2000/31/EC. The direc-tive strives to create a similar law for electronic commerce within the European Union. This paper?s main purpose is to ensure that the directive is implemented properly in Swedish law, and if there are other possible ways to achieve the objective, other than the ones that the Swedish legislator has chosen.
