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.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

This thesis presents an application that performs positioning of modules automatically based on given data for every module, and the development of it. The basis of the application is from a previous thesis code. On top of that code, more features and error handling has been added, as well as fixes for various bugs. A stress test has been performed and further development possibilities are being presented.The thesis work was carried out at Toyota Material Handling Mjölby (TMH) and was made in parallel with another thesis by Fredrik Holden who was generating data for the application. For a complete understanding of the theory and background, please also read Holden?s thesis report ?Development of method for automated positioning of 3D-representations of a modularized product?, as well as the former thesis  ?Analysis for Automated Positioning of 3D-representation of a Modularized product??..

The invisible entrepreneurship is a study of owners of businesses with foreign heritage. It describes the unexplored relationship between ethnicity and class within this group of entrepreneurs.The result of the study is a model which I have found to be suitable to use when depicting the relationship between the ethnic profile and class. The model indicates that the importance of ethnicity decreases as both the owner of, and the business reach a more prominent class. The method of collecting data has been interviews with owners of businesses and Grounded theory has been used to analyse this data. Theories on ethnicity, owners of businesses with foreign heritage, and class in relation to ethnicity have been discussed on the basis of social constructivism.

Med utgångspunkt att självskadebeteende är ett internaliserat problem är syftet med studien att i en ungdomspopulation undersöka om självskadebeteende även är länkat till externaliserade problem. Vi undersöker även om självskadebeteende hänger samman med att i olika miljöer utsättas och utsätta andra för negativa beteenden. Studien använder redan insamlade data i forskningsprojekt kallat - ?Sju Skolor?: Center for Developmental Research (CDR). Data samlades in från 1478 högstadieelever.

Detta är en studie kring ämnet intelligent videoanalys som verktyg för framtagandet av rörelseanalyser. Rörelseanalyser är ett brett begrepp då rörelse kan ske på många olika sätt. Det kan vara rörelse av fotgängare, cyklister, bilister m.fl. Dagens analyser av rörelsemönster baseras bland annat på intervjuer, observationer, egna erfarenheter, spår i marken, som en del av andra analyser (Bland annat genom Kevin Lynch och Jan Gehl) eller koppling till befintliga strukturer. För att få verklighetsbaserad data under en längre tidsperiod och för att kunna utföra mer djupgående analyser av rörelsemönster hos fotgängare på offentliga platser krävs nya verktyg.

This study investigates how productivity works when employees have remote work in their workplace. This study will also focus on challenges that cause productivity to decrease when remote work applies. The empirical data shows that individual productivity increases when employees work in a workplace that provides remote work. The data says that less distractions and high autonomy is a big factor to why employees feel that they work productively at home. Briefly it shows that a flexible workplace makes individual employees work productively and even motivates employees to work effectively because of increased concentration and undisturbed work environment.

During some time there has been a debate whether or not logging contractors? profitability can be considered poor. The contractors? situation is important for maintaining long term relationships and continuity in the forest industry. A thorough analytic picture is however missing.

Destination branding is becoming increasingly acknowledged by regions working with tourism. Underlying is the fragmented web of actors in the supply chain of which the tourism product consists of. The main purpose of our thesis was, from a management perspective, to gain an understanding and describing how a network and the actors within it can build a consistent brand. We therefore chose to make a case study research on The Kingdom of Chrystal, or Glasriket, which is one of the most famous tourist destinations in Sweden. Our research is based on theoretical and empirical data.

Prestanda är idag en av de viktigaste faktorerna för en webbapplikation. Då mer och mer tid för en webbapplikation idag dock läggs på att hämta data från t.ex. en databas, krävs tekniker för att effektivisera hämtningen av data. En teknik som kan användas för detta är cachning, som dock ställer ett antal utmaningar. T.ex.

Dagens moderna organisationer driver vanligtvis en kostsam IT-baserad infrastruktur. De besitter högpresterande funktionalitet och säkerhet för att garantera att de dagliga operationerna fortskrider. Mjukvarubaserade lagringsplattformar är ett alternativ som kan användas för att reducera dessa kostnader. Genom att efterlikna avancerad teknik som redan existerar i traditionella lagringsplattformar kan detta implementeras som mjukvara på commodity hardware i syfte att uppnå samma funktionalitet. Ceph är ett alternativ som numera implementeras och ämnar erbjuda detta val.

The purpose of the thesis is to investigate whether a higher income make individuals more likely to exceed the speed limit. In addition to income the variables age, sex, perception of the speed of the average driver and offense history for the last three years are taken into account.The method used is based on a survey performed at the mandatory annual motor-vehicle inspection (Bilprovningen). 177 individuals were asked to participate, of these, 124 completed the survey which in turn left us with 117 usable observations.The analysis is based on two forms of regression, a linear regression and an ordered logit regression to confirm the results for the ordinal data.The final model indicates a result where income and age are statistically significant. Sex is considered insignificant for our data material and is excluded from the model. Age has a negative effect on the propensity to exceed the speed limit while income has a positive effect.

In all types of learning situations, it is important to find each student where they are at the moment in knowledge. I have reflections about  what animal experience students have with them when they begin their education. This thesis is about what home environment and in home environment acquried animal experience student at agricultural college have. This work is based on data collected through questionnaire survey done in two agricultural colleges in middle Sweden in the spring of 2007. Questions were divided into four blocks, historical data such as on the environment in which pupils are growing up, animal habit, why they read on agricultural school and future data on what plans students have for future education and careers.

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.
