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.

When I was fifteen I decided that I wanted to become a blacksmith. At the time of my decision I had been obsessed with fantasy for several years. I came to the conclusion that if I could not live in a fantasy world then at least I would make bits and pieces from it. That became the entry point of my fascination for material and techniques. I started with blacksmithing since it had an aura of magic or mystique in the material and in the making process.

The common literature about strategic alliances offers a very fragmented picture. This thesis gives a theoretical overview on strategic alliances and builds the basis for the following examination of the different dimensions most strategic alliances have. The examination of the different dimensions is the crucial point of this thesis. Here the reader gets a detailed insight into the different dimensions and the implications they have on the design of a particular strategic alliance. This examination leads in the end to a more differentiated view on strategic alliances and the insight that no simple models exist, which give a sufficient basis for decision-making and understanding strategic alliances, today.

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

This work was conducted during spring and summer 2012 together with the company Uppsala Academy of Management as the principal. The two main objectives for the work are that: ? Make a comparison between the measured volume in the standing forest and the measured volume at the industry on Uppsala Academy of Managements actual stumpage sale volume to see how well it conforms. ? Examine if the buyers see any particular advantages or disadvantages of actual stumpage sale volume and what they think of Uppsala Academy of Managements actual stumpage sale volume and structure in general. I chose to use actual stumpage sale volume from the tree years 2009, 2010 and 2011 in my work. I divided the actual stumpage sale volume following four categories which was pine, spruce, pine/spruce and seed trees. After that I picked out sixteen actual stumpage sale volumes from each category to be a part of the work.

I denna studie har vi undersökt vilka strategier som är viktiga att beakta vid implementering av beslutsstödjande system. Vi har utgått från Alters (1980) teori, där han beskriver ett antal strategier som delas in i olika kategorier, och jämfört denna med empirin som vi undersökt vid tre företag. Vår undersökning visar att de olika strategierna inte beaktas och tillämpas i lika stor utsträckning. I vår undersökning har vi funnit att strategierna som ingår i kategorin utveckla en tillfredsställande grund är särskilt viktiga att beakta. Vi har även funnit grund för en kompletterande strategi som behandlar vikten av att identifiera, möta och säkerställa informationsbehovet hos intressenterna..

I have been studied Microsoft SharePoint on behalf of Prevas in Karlstad.The purpose of my work was to see if Microsoft SharePoint was what Prevas wanted as a replacement for the existing intranet, which they are not satisfied with today.My work was a kind of foundation for Prevas so they could make a decision in this matter.The work began with installing SharePoint at one single server at Prevas. We used a virtual technology (VMware) at the installation, which can be described as that we created two ?miniservers? in a bigger server, one for SharePoint and the other for storing the information. This kind of technology is strongly advancing. The main work consisted of setting up the structure for the navigation and designing both the portal and the local homepage for Prevas Karlstad.

From interviews with biology teachers and pupils, some important factors are presented that motivates and interests pupils in biology. Some of these are varied education, commitment of the teacher, narrative skill and individually reachable goals. Other important factors are practical application and connection to daily life, as well as actuality of the subject and pupils experience of the use of learning.Circumstance around teacher and pupils will influence which factors that has the most impact. It´s up to each teacher to make a decision which factors to be used based on his or her own qualities and depending on the group they will teach.Teachers and pupils agreed about factors that will cause an interesting lesson. The pupils emphasize that variation is the most important factor.

Fungi are everywhere around us and recently, there has been an increased interest in their role and importance in the forest. The fungi have several strategies to acquire energy and nutrition; one example is a mutual symbiosis with trees and plants - another being dissolving organic materials. Attempts have been made to better understand the circulation of nutrition in coniferous forests, and how fungi cooperate. Trees and plants have adapted with mycorrhizae and are now interdependent which is important to consider in forestry. A great number of fungi depend on dead wood and old trees to set fruiting bodies and spread further. These fungi also create environments for other species, such as birds and insects. The vegetation of a forest is determined by a series of factors; tree species, how old the forest is, soil type, as well as the ability of the fungal spores to spread and establish. Furthermore, in determining vegetation, the fungi?s ability to compete in the soil matters. These factors are nearly unexplored. Researching fungi knowledge and interest, a survey was distributed to five groups of people. The groups included forest owners, high school teachers, high school students, senior citizens, and a fifth group - ?o he ? - consisting of people of mixed ages and backgrounds.

Urban trees contribute significantly to our society. By providing ecosystem services and a habitat that other urban species and ecosystems depend on, both biodiversity and the people in the city benefit. Some characteristics that the trees possess include functioning as biological filters for the atmosphere and water, as well as positively impacting people's mental health. However, urban trees are challenged by stressors such as pollution and a drier environment, making them particularly sensitive to climate change. The goal of this study was to estimate the expected magnitude of climate change in Gothenburg and compare it with the current urban species' natural climate boundaries to understand the extent of the climate threat and which species appear to be most at risk.

The purpose of this essay is to examine the United Nation?s work and structure to find possible factors that can explain why some peacekeeping operations have achieved to mainstream a gender perspective, when others have not. This study is based on two cases; the peacekeeping operation in Namibia and the peacekeeping operation in Kosovo.The theory I have chosen to apply is feminism, a theory that allows an alternative explanation to this phenomenon. The conclusion is that there are three decisive factors: The leadership and its will to recruit female personnel to decision-making positions, the number of female employees and whether the peacekeeping operation cooperates with local women-organisations or not. All this is of great importance whether the institutional hegemonic masculine culture within the United Nation and its peacekeeping operations, is challenged or not..

This rapport is about how often private forest owners follow the measures proposed in their forest management plan. The survey is made in cooperation with the forest-owners association Norrskog. The private forest owners are relatively satisfied with the forest management plans and with the measures proposed. There are some differences between those who live on or near their property and those who live many miles away. The forest owners who live on their property are those who follow the proposed measure of precommercial thinning to the largest extent. That group also values precommercially thinned stands higher than thinned stands. The complete opposite is the case for the group that lives far away from their property. Almost all of the respondents thought that the forest management plan would be or had been a good help in the decision making about the forest..

The purpose of this study was to interview different groups of people (preschool teatcher, parents and theire childen) involved in preschool about their view on outdoor activity and children´s motoric development, and how a preschool yard should be designed to promote childrens development.All parties regard outdoor activity as very important for the development of children. They also think that the outdoor environment today is good but that it could be improved by including some trees and hills. The yard should also contain soil, sand, clay and water. The children prefer grass on the ground over other substrates. This study also gives good indications to decision makers how to build new or to reconstruct pre-school yards in the future..

The conception of exhaustion was first used in the end of 1960 and was then used in a psychological context directed towards the working life. Eventually was the conception devided into two main categories: mental and somatic symtoms. Today research of exhaustion is mainly aiming towards recovering and returning to working life.This work sets out to analyse the importance and effects of social networks such as family, friends and professional relations in helping people who suffer from exhaustion to recover. The study is based on interviews with eith people who have suffered from exhaustion but today are recovered. To my aid I have used tree different questions: What part have the social network of family and friends ment to the recovery? What part has the professional relationships with doctors, therapists and curators ment to the recovery? How have you changed your life in order to maintain balance?The interviews pointed out the importance of the social relationships as support, feedback and understanding that the process takes time.

The company Betsson opened its first physical gambling shop in Sweden in May 2008, thereby defying the Swedish government?s legal gambling monopoly. The legal case that has resulted due to the violation of the Swedish gambling law has attracted immense attention from mass media, thus generating vast amounts of publicity for the company. This paper aims to evaluate and describe the company?s decision to open the store, as well as to examine the relationship between market driving practices and market driven practices.
