Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)
The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.

Kunskapsfabrikens rötter
The purpose of this study was to investigate, through a qualitative survey, the need of knowledge and strategy in organisations today and tomorrow. The empirical investigation is built on a semi structured interview that was conducted on nine different companies in Gislaveds community. The companies were from three different branches namely: tree, metal and polymer. Three interviews were conducted in each branch.The result from the interviews showed that the globalisation had put the companies under hard competition which had made the need for rationalisation and effectivness more apparent. Having said this, the demands on the organisation and the individuals within it will constantly increase.
Lost World : Home of the seven and a half legged tree
The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.
Utvecklande AI - En studie i hur man skapar ett system för lärande AI
AI är något som blir allt viktigare inom dagens spel och får allt högre krav på
att agera mänskligt och intelligent. Detta kandidatarbete undersöker vilken
metod som är att föredra för att skapa en AI som kan lära sig av sina tidigare
erfarenheter. Några av de metoder som undersöks är trädstrukturer, Artificial
Neural Network och GoCap. Genom att skapa en applikation med en av metoderna
samt göra en undersökning på hur AI:n i applikationen upplevdes fick vi
resultat om denna metod var användbar. Utifrån detta diskuteras det ifall andra
metoder hade varit mer effektiva, hur man hade kunnat förbättra AI:n samt hur
framtiden för spel-AI skulle kunna se ut..
Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige
Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.
Effects of storage time, die channel length and moisture content on pellet quality of lodgepole pine (Pinus contorta Dougl. var. latifolia)
The use of renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus contorta Dougl. var. latifolia) is of particular interest, mainly because of its high volume production.
Digitala fotogrammetriska arbetsstationer för skoglig flygbildstolkning :
SCA Skog has taken the initiative to this Master?s thesis. Today SCA Skog has a great need to update their informtion on young forest stands across large areas. Traditional field inventory methods for updating stand databases are expensive and time consuming. However, the inventory could be made more efficient if stand boundaries and stand characteristics are derived from aerial photographs.

Förslag på sju olika träd som kan ersätta befintliga träd på kyrkogårdar
Växtligheten på dagens kyrkogårdar har i regel knappt en 100?200-årig historia. Det var i slutet av 1800-talet som kyrkogården efterhand fick det utseende som vi förknippar med en gammal kyrkogård, med höga kyrkogårdsträd och en kyrkogårdsmur.Det trädsortiment som har använts i trädkransen som inramar kyrkogården eller trädrader längs gångar, har varit begränsat beroende på traditioner och trädens lämplighet. Man valde ofta arter utifrån de lokala förutsättningarna, såsom alm, lind, lönn och björk. Under en längre tid har sjukdomar på en del trädarter brett ut sig och hotar trädbestånden på våra kyrkogårdar.
En fallstudie av Södertörns högskolas intranät Kurswebben
We have made a qualitative study of what the students at Södertörns högskola use Södertörns högskola?s intranet Kurswebben for and how they experience the use of it. For this purpose we have made a qualitative interview examination with six students. The empirical material has been analysed according to our own analytic model which is based on existing usability theories and consists of the tree parts content, function and design.Our conclusion is that the students use Kurswebben mainly to keep themselves updated, download teaching material and schedules. According to our study, the students most of the time experience their use of Kurswebben as simple, but sometimes have a reluctance to visit it.

Underröjningsgradens påverkan på förstagallringsnetto med flerträdsaggregat
I Sverige finns ca 1,2 miljoner hektar skog som bedöms ha omedelbart röjningsbehov. Skog där röjningen uteblir eller är svag kan komma att klassas som konfliktbestånd. I konfliktbestånd är stammarna många och diameterspridningen stor och dessa kan då behövas underröjas innan gallring. I denna studie jämfördes produktionen, kostnaderna och intäkterna från fyra olika underröjningsbehandlingar, oröjd, siktröjt, röjt allt upp till 5 cm i brösthöjd och röjt allt upp till 7 cm i brösthöjd. Behandlingen oröjd gav det bästa nettot och sämst hade upp till 5 cm efter gallring och uttransport av virke.

A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.
Språkets betydelse för matematikinlärningen
Study aimed to see if the language has bearing on mathematics learning. The study used qualitative interviews of three first grade teachers and one special education teacher.The questions asked was:Do the teachers and specialist teacher, at the selected schools, think there is a connection between language difficulties and difficulties in mathematics and in case how is this connection.How does the teachers / specialist teacher make it easier for students to learn mathematics and swedish.The study was based on Vygotsky and Piaget teories. In previous research, it is primarily Malmer, Hoines, Lowing and Kilborn who´s been treated. Within the governing documents, it is mainly the compulsory school curriculum Lpo-94, and the curriculum for mathematics treated.I hope that the study has conclude that there is a connection between language and mathematics learning.I tried to emerged this through interviews with tree teachers and one special teatcher but i couldn´t. The teatchers couldn`t fint that it was the only reason to why the pupils hade difficulties in mathematics.But in the literature I found the relation between language- and mathematicdificulties..
