To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

This field study examined how elderly and cognitively disabled people used and experienced a social companion robot. The following pages explores the questions: Which are the physical, social and affective qualities during the interaction? The aim was to through observations see how qualities of interaction could activate different forms of behavior. The results show that motion, sound and the eyes together created communicative and emotional changes for users who felt joy and were willing to share the activity with others. The robot stimulated to some extent users to create their own imaginative experiences but often failed to involve user or group for a long time and was also considered too large and heavy to handle..

Aim: The study aims to investigate the distribution of grades between students in a practical subject and in a theoretical subject.The problem:What is the grade distribution in physical education and mathematics, with respect to gender, socioeconomic background, parental education, ethnicity, and physical activity?Method:To answer the aim of the study a quantitative method was chosen. As the collection method used was questionnaires to 620 students in the 9th grade in Stockholm. Of the 620 questionnaires, 597 questionnaires were used for the static analysis. The method of analysis used cross tables and logistic regression analysis.

The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student?s being socially active offline, tend to use the media to a greater extent than those less active..

Background The Shetland Sheepdog is a popular breed of dogs in Sweden. The breed is mostly used as a companion dog and is also popular within certain dog sports such as agility. The Shetland Sheepdog is not included in any breeding programs regarding joint health. The animal insurance company, Agria had recently informed the Swedish Shetland Sheepdog Club (SSSK) that they had noted an increasing number of arthritis in the elbow joints, therefore they wanted to exclude elbow joints from the insurance until SSSK started a breeding program against elbow dysplasia. After the start of this study Agria withdrew their demand, but the study went on as planned. Aims of this study The aims of this study was to investigate if there is any data that may show if there is a larger or smaller reason than before to suspect that the breed has a problem with elbow dysplasia and therefore would benefit from a breeding program regarding this.

Saab Component Maintenance in Linköping, Sweden, offers maintenance, repair andoverhaul (MRO) services for civilian and military aircraft components. Lately, thedepartment has struggled with slow throughput rates, despite various counteractingattempts. Studies show, that large parts of the delays derive from the logisticsdepartment where goods arrive and dispatch. Therefore, Saab wants to carry out anextensive analysis of the department in order to further investigate what is causing itsslow throughput rates.The thesis begins with extensive mapping over Component Maintenances whole valuestream to find out how departments interact with each other and which roleindividual departments have in the total supply chain. Out of 13 000 different partnumbers, components were divided into five product families.

Examensarbetet Utomhuspedagogik för andraspråksinlärning är en kvalitativ studie där jag har intervjuat fyra pedagoger, två lärare och två naturpedagoger. Det har skett genom semistrukturerade intervjuer utifrån en intervjuguide. Dessa har alla medverkat i utbildningsprogrammet Aktiva Ute där ungdomar i åldrarna 16-19 år går en naturvägledarutbildning. Hälften av ungdomarna har svenska som andraspråk. Enligt litteraturen så lär sig elever språk genom samspel med andra kompetenta samarbetspartners.

Lower urinary tract diseases are a common problem in cats all over the world. The symptoms are for example dysuria, pollakuria, stranguria, periuria and hematuria. In approximately two thirds of these cats the underlying cause is not known and the disease is therefore called feline idiopathic cystitis (FIC). We need to know more about the disease to get a consistently effective treatment and prevention. A retrospective study was performed in 50 cats with symptoms of FIC and where other causes of inflammation were ruled out. Data like breed, age, sex, body weight, feeding, therapy and therapeutic results were collected, also if it was an indoor or outdoor cat, duration of the symptoms, if there was any stress and if the cat was living with another cat.

Asthma is one of the most common diseases among children. The aim of this study was, through a literature review, describing children's experience of living with asthma and show how negative experiences can be turned into positive ones, by the nurse's work. Results showed that many of the children with asthma experienced respiratory- and chestproblems, tiredness, panic, fear, anger, frustration, discomfort, irritation and anxiety. Children felt most restricted in physical activity's. Education used to enhance children's experiences included relaxation, imaginary exercises and confidence training.

Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

"Ekskolan" is a monumental school placed in the middle of the new town area "Mariehäll" in Stockholm, Sweden. 600 pupils between preeschool until year 5 will use the school and its big schoolyard between the townsquare and the public park.The school will be built in massiv wood, both for human reasons with a environment of good, healthy and suitable material for the people and the school activity.The school is seperated in 3 volymes that organises different years; house B and C, and the common facilities: house A. The scool has a cultural profile with rooms for creative activites, documentation and exhibition.To mark the border to the public places that surround the scool and to meet the inclined topography, the schoolhouses will stand on a terrace. The terrace creates rooms between the houses that can be used to utdoor teaching. Likewise, the terrace creates a opened sightline between the public rooms and all the way down to the river..

Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling. The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.

Gångproblematiken hos personer med Parkinsons sjukdom är svårhanterad av både vårdtagare och vårdare och kräver mycket kunskap och förståelse. Syftet med denna litteraturstudie var att identifiera omvårdnadsåtgärder som kan underlätta gångproblematik hos personer med Parkinsons sjukdom. Tio kvantitativa studier har används i denna litteraturstudie och sökningar har gjorts i Pubmed och i CINAHL. Resultatet från dessa sökningar presenterades i fyra strategier och fynden var rehabilitering, individanpassad träning, stimuli och användandet av dagböcker. Dessa strategier kan användas som verktyg för en sjuksköterska när hon interagerar med personer med Parkinsons sjukdom.
