Lantmäteriet (the Swedish mapping, cadastral and land registration authority) has been laser scanning Sweden since 2009. From the laser scanned data a digital elevation model (DEM) in grid format, with a resolution of 2 m, is produced. This DEM is called GSD-Höjddata, grid 2+ and from its data and the laser point cloud itself (in the form of a las-file) contour lines can be extracted. Lantmäteriet has not yet done this, but plans to update the contour lines in their cartographic products exist. If this is to be done in a satisfactory way an evaluation of different methods for it is needed.

In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..

Vid additiv tillverkning så skapar man en produkt genom att sammanfoga material, till skillnad från traditionella maskinbearbetningsmetoder som är så kallade subtraktiva tillverkningsmetoder där en produkt skapas genom att material tas bort från ett råmaterial. I denna tillverkningsmetoden så utgår man från en CAD-modell av produkten. Vid produktionen så läser den additiva tillverkningsmaskinen hela tiden av modellens tvärsnitt och lägger på material lager för lager tills produkten är färdig.Syftet med detta arbete är att undersöka om additiva tillverkningsmetoder kan användas för att ersätta konventionella byggmetoder vid byggandet av enfamiljshus i framtiden. I arbetet undersöks även i vilken utsträckning som detta kan ske. För att besvara på detta så undersöks, förutom konventionella byggmetoder, även bygge av hus genom att använda prefabricerade byggelement, då detta eventuellt kan vara en konkurrent till de additiva tillverkningsmetoderna.

The aim of this thesis is to study the possibility of the existence of a specialist in bone tools manufacturing during the Mesolithic. The thesis describes the climate during the Mesolithic, argues for an experimental approach, and describes social organization in hunter-gatherer-groups and the processes behind cultural transmission. It also gives some examples of excavation sites in Scandinavia. An experiment simulating a teaching situation is made, in addition to the theoretical information, with the intent to explore how advanced the crafting of bone really is. The physical result is then studied and documented.

This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.

The concentration and storage of organic chlorine and chloride were determined in soil, to a depth of 40 cm, in a coniferous forest in the Stubbetorp catchment area in south-east Sweden. Also, the spatial distribution of the two forms of chlorine was determined. Soil samples were collected at 49 of the nodes in a grid with approximately 105 m between the nodes. The analysis of spatial variability suggested that no spatial autocorrelation was present either within the variable organic chlorine or chloride. This means that no sample was more influenced by another nearby sample, as compared to other samples further away.

Body awareness is a term that refers to a person´s perception and knowledge about his or her body. It includes proportion, size, weight, contour and image of ones body. The Ben- Tovim Walker Body Attitudes Questionnaire (BAQ) contains 44 questions concerning the different aspects of body awareness: Feeling fat, Body disparagement, Strength and fitness, Salience of weight, Attractiveness and Lower body fatness. The purpose of this study was to investigate body awareness among men in military recruit training. BAQ was distributed to fifty recruits for military service in Boden.

This paper deals with knives excavated in the Birka Garrison between 1997 and 2004, in a selection of 100 knives out of approximately 400. The aim is to measure and analyze the material to find out if certain elements in design points to a specific craft. Two groups of knifeblades can be seen, one with a convex bevel and one with a flat bevel of the blade. Considering osteological evidence, historical sources, and the main suitabillity of the knives, it is concluded that some of the flat beveled knives may have been used for crafting leather and fur, whereas the convex beveled knives are of an allround type..

Byggbranschen är i förändring och sättet att bygga utvecklas ständigt. Dock kritiseras ofta byggbranschen för att vara dålig på att utvecklas och inte uppdatera sig i den hastighet som behövs. Något måste göras för att snabba på utvecklingen och kanske kan 3D-skrivare vara ett alternativ i framtiden. Detta examensarbete syftar därför till att ta reda på mer om den nya tekniken och dess möjligheter för att kunna förbättra byggprocessen.Examensarbetet handlar om att ta reda på vad som finns idag när det gäller 3D-skrivare och att försöka ta temperaturen på tekniken. Kan man använda en 3D-skrivare för att skriva ut komponenter eller kanske till och med ett helt hus? Finns det någon som börjat inom byggbranschen? Går det att börja använda 3D-skrivare redan idag?För att ta reda på vad som finns började arbetet med att söka information på internet.

The Swedish language contains contrasts of tonal word accents, realized by change in the F0 contour. Contrasts of word accents require at least two syllables with stress on the first syllable of the word or a stressed syllable followed by a non-stressed.The purpose of the present study was to examine how five-year-old children living in Östergötland with typical language development produce and discriminate tonal word accents. In addition, it was investigated how these abilities affect each other and comparisons were made to a similar study on children living in Skåne.For elicitation of tonal word accents a set of pictures with contrastive tonal word accents was used. The children were recorded and their answers were evaluated by visual classification of their F0-curves. In a perceptual analysis of the children?s productions, 11 linguistically naive listeners evaluated 44 randomized words from the recordings.

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.

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

 The current estimations in regards to the increase in environmental threats underline the importance of influencing individual behavior towards a more sustainable lifestyle. At the same time current trends show an increasing interest into ecologically produced foods around the world and that the consumption has seen a major rise in the 20th century. It is therefore of great importance that companies show their interest and commitment in order to offer and influence the consumer into choosing the environmentally sustainable alternative. Also, in order to properly reach out to the consumers, it is of outmost importance to map out their attitude towards these types of products. It is equally important, in order to fully realize the potential of successful positioning, to show an understanding for the underlying decision processes that dictates purchase.
