In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.

Optimering är ett ständigt problem att brottas med som inom spelbranschen. Endatorgrafiker som arbetar med spel ska inte bara skapa så estetiskt tilltalandemodeller som möjligt utan måste även få dessa att fungera tillsammans med detekniska krav som ställs utav industrins spelmotorer och hårdvara.Tesselering och displacement mapping är ett exempel på industrins olikatekniker för att ge spel en mer realistisk rendering genom att förbättra siluetter,ge mer korrekta detaljer och samtidigt avbelasta tunga beräkningar från CPU tillGPU genom att utföra geometrins polygonhantering på grafikkortet.Tesselering och Displacement Mapping har börjat öppna upp nya möjligheterför hur moderna spel kan se ut och som datorgrafiker så måste du kunnaidentifiera när, var och hur dessa tekniker bör användas.Detta examensarbete går igenom modellering, bakning och användning avdisplacement mapping på tesselerade geometrier inom en rad av grafiskaanvändningsområden med hjälp av ett par enkla tester i hopp om att göra digsom läsare redo för att skapa realistiska modeller..

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.

This study aims to examine how performance management is compatible with the operations at Sida, Sweden?s International Development Cooperation Agency, by performing interviews with representatives from Sida. The public sector is facing increased demands on accounting, which has emerged as an institutionalized social norm in society. The nature of Sida?s operations, however, proves to be highly complex, rendering results based management difficult to implement.

Jag bestämde mig för att skapa en diktsamling för mina dikter som jag skrivit under en längre tid. Det jag vill undersöka är hur man kan använda sig av Storytelling för att skapa en helhet för en diktbok. Jag ville införa detta element i både innehållet i dikterna, vilken plats de skulle få i boken samt få in det i formgivningen. Jag tog och använde mig av litteratur för vägledning inom hur jag skulle få fram den historia som jag hade att berätta. Resultatet blev en komplett diktbok som med formgivning och placering av dikterna blev en bok som berättade en historia för sig själv i sin helhet..

This essay examines the love affair between the two main characters of Rut Hillarp?s novel Sindhia. It draws attention to the schism between the Surrealist version of love as an extatic-religious fusion of the sexes ? that in a way marks the relationship ? and the yet remarkable coolness between the two lovers.With the theories of French psychoanalyst Jacques Lacan, I will show how the man and the woman project their unrealistic individual fantasies on each other, thus rendering impossible the Surrealist Meeting, with its road to an absolute reality. The Surrealist "l?amour fou", I will argue, is trapped in the ritualized "l?amor interruptus"; a lacanian term for a certain kind of love that wishes to conceal the fact that desire will never find its object.

The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.

Konstruktion utav stora stadsmiljöer i 3D består, från idé till färdig scen, utav många olika processer och tekniker. Från koncept genom planering, modellering, texturering och rendering till slutresultatet. Det är därför önskvärt att minimera mängden onödigt arbete och effektivisera dessa processer där det är möjligt. Den här studien undersöker hur modularitet kan användas och implementeras i semi-automatiserade konstruktionslösningar i syftet för att användas i filmsammanhang. Kärnan utav studien utgår ifrån att en grafiker skapar diverse byggstenar för olika stadsmiljöer.

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

This report was written as a result of a Bachelor Degree Project at the School of Technology and Society at University of Skövde, first semester 2007. The assigner was Tibrokök in Tibro, Sweden. The commission was originally to design a sliding door concept for kitchen. Later it was expanded to also include bathrooms.During the feasibility study of the project Internet was used as an information source. Kitchen brochures and magazines were ordered from different companies to give inspiration and ideas.

A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to provide interactive real-time animation and visualisation of the simulation results. The work focuses on two themes and the integration of them. The first theme is the storage and management of the large data sets produced.
