This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

The purpose of this paper is to standardize and simplify the design work on a few specific types of storage brackets for balconies. The company Balco AB had the wish to simplify the design work in the preparation of attachments to their balcony structures. This would be done by a calculation matrix that could be produced which then in turn could be used for each new project by the company. The design work behind the development of these fittings at each new project is costly both in terms of time devoted by each calculation but also the cost of the time. The purpose of this report is that in a systematic manner, a calculation matrix can be created that then the company instead may follow from each new project.In carrying out the project used HILTI calculation program, which was provided by the company HILTI.

Forest management contributes to the changes in forest structure by turning heterogenous forests of varied age into homogenous forests of similar age and thus affect bird species depending on different structures or habitats which are lost during forestry. In this report, a study was made to investigate how the amount of decidious trees, dead wood and variation in tree diameter affect bird diversity. The purpose of this study was to be able to give forest management guidelines to increase bird diversity. This study was conducted by investigating 65 transects in forests of different structure south of Linköping, Sweden. Along the 65 transects, birds were inventoried as well as the vegetation.

The purpose of this study is to present arguments concerning a zestful learning for children ages 6-9 in mathematics. Four books in mathematics has specifically been analyzed to investigate what is written concerning a zestful learning. By means of an argumentation analysis within a qualitative text analysis the arguments are put forth. The didactic choices of the chosen literature are analyzed in a subject-matter didactic context. The result implicates a multitude of arguments and didactic choices supporting a zestful learning.

This study is about being manager in social care and social welfare organisations. Ten women managers participate in the study and share their thoughts about management. Such organisations are an area where women are most frequent, so we wanted to take part of experiences women managers in this area obtain. The study concentrates upon factors these women encounter and which they feel can affect them in their daily work. The study shows that the women we interviewed have a basic interest in humans and a strong commitment to working for human well being.

Reptiles are animals than have been neglected in the research for all times. Some people have the opinion that these animals have fewer needs and demand less from their caretakers. The Aldabra Giant Tortoise lives on the Aldabra atoll outside the coast of Tanzania. The Aldabra tortoise population has varied throughout the years, but today the population is around 100.000 animals. The purpose of this study was to analyze the enclosure utilization of two Aldabra tortoises, a male and a female, at Parken Zoo in Eskilstuna, Sweden.

Syftet med detta examensarbete är att få en bild av hur eleverna ser på motivationen under matematiklektionerna, samt om eleverna upplever någon skillnad mellan låg- och mellanstadiet i matematikundervisningen vad gäller motivationen.I bakgrunden presenteras motivation utifrån några olika definitioner. Olika begrepp inom motivation så som inre och yttre motivation, prestationsmotivation och flow beskrivs samt att tre olika teorier belyses.Studien är gjord i Kalmar och sammanlagt har 23 elever intervjuats, 11 elever från årskurs 3 och 12 elever från årskurs 6.Resultatet visar på att det är olika faktorer som inverkar på elevernas motivation men att det framförallt är elevernas inre motivation som påverkar. För att eleverna ska uppleva matematiken mer motiverande krävs dock att det används mer praktiska uppgifter så som spel och lekar i undervisningen. De elever som medverkade i undersökningen upplevde att matematiken är mer motiverande på mellanstadiet då uppgifterna är mer utmanande och eleverna ser en användning av matematiken i det vardagliga livet..

The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.

The aim of this study was to investigate which factors teachers and special needs education teachers view as being the main causes of mathematical learning difficulties and from these choose how to educate pupils with these difficulties. The aim was also to investigate how this education is organised at two different schools. An interview based investigation addressed these objectives by using three comprehensive questions:Which factors do the teachers and special needs teachers view as being the main reasons for mathematical learning difficulties?How do teachers and special needs teachers educate pupils with mathematical learning difficulties?How is the education organised for pupils with mathematical learning difficulties at two different schools?This study is based on four interviews of three teachers and one special needs teacher. The people interviewed work at two different primary schools in the same local authority.

This work studied the information flow and information handling among different parties. The study focused on how educational materials on national tests from The Swedish National Agency for Education is managed by school principals and teachers and how the information is passed on to students. The data material was based on observations and interviews at two different high schools. Six teachers and their classes and principals participated in the study. The Agency was also interviewed.

Dagvatten kallas det regn- och smältvatten som rinner av från hårdgjorda ytor i stadsmiljön. Detta vatten för ofta med sig stora mängder av föroreningar som tungmetaller, näringsämnen och oljerelaterade ämnen, vilka kan göra stor skada om de når recipienter. För att rena dagvattnet och därmed minska föroreningsbelastningen byggs det allt fler öppna dagvattensystem som t.ex. våtmarker och dammar. Studier har visat att dessa system har hög reningseffekt och dessutom är de kostnadseffektiva.

Millions of animals are annually affected by human activities; in the food industry, zoos and animal shows, clothes and shoes production, furniture and pharmaceutical industry, research, as well as pet and sports animal industry. Companies working with Corporate Social Responsibility, CSR, have become more common and within this area there are great possibilities for companies to work with animal welfare. In this study five companies were interviewed and 27 companies participated in a survey regarding CSR and animal welfare. The aim of this study was to investigate opinion and approach among companies towards implementing animal welfare as a part of their work with CSR. Furthermore the aim of the study was to investigate how companies may implement animal welfare. The result showed that the vast majority of the companies participating in the study works with CSR and the main part of the companies also answered that they have implemented animal welfare. The way of working with animal welfare varied among the participants; e.g.
