The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Studien avser undersöka hur unga Jehovas vittnen håller sin tro övertygande. Frågeställningar har varit hur de hanterar den mångfald av världsuppfattningar, värderingar och normer som inte är förenliga med Jehovas vittnens lära, hur deras tro bekräftas kontinuerligt samt om de upplever sig skilda från den icke-troende världen. Tre unga Jehovas vittnen har intervjuats för denna studie. Deras svar har relaterats till vad tidigare forskning och sociologiska teorier säger om att hålla tro övertygande, att vara ung och religiös samt om att vara ett Jehovas vittne. Frågeställningar och syfte besvaras genom ett flertal faktorer som träder fram i studien: församlingen utgör en starkt normbildande primärgrupp och utgör en stabil plausibilitetsstruktur.

Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.

With regard to PlymoVent's business strategy and reference theory, the demands of how to receive and monitor a supply chain for a better customer satisfaction where targeted. The findings refer to poor customer satisfaction due to obscure procedures in problem resolution and discrepancy handling, and vague transportation accuracy..

The purpose of this essay is to examine different conceptions of God children express in speech and image. The essay also concern how children's images of God are shaped in a secular and pluralistic society, such as Sweden. The children included in the investigation are in first and third grade in middle-sized Swedish town's primary school. In the essay, two methods are used, which is picture analysis and qualitative interviews. The material consists of 47 children's drawings and a smaller selection of interviews with the child's drawing as a starting point.

With the increased significance of information technology (IT) in today?s society the term ?electronic democracy? (e-democracy) has gained much importance within the democracy theory. Naturally, there are several competing views on how the technology should be used for democratic purpose. One aspect of this is the somewhat revitalized claim for direct democracy in accordance with the hypothetical opportunity to finally realize it as a democratic system. The ideal of direct democracy combined with the almost total credence in the potential of technology constitute the idea of a ?push-button democracy?.

Bakgrund. En gyllene standard för att bestämma noggrannheten för intraorala scannrar existerar inte. Intraorala scannrars prestanda som ges av olika leverantörer är inte fullt jämförbara. Det finns ett behov att standardisera och ta fram oberoende försöksupplägg för att kunna jämföra intraorala scannrar. Mål. Målet med studien var att beskriva och utvärdera en ny metod för att bestämma noggrannheten av intraorala scannrar genom ett standardiserat in vitro testförsök och att använda metoden för att beräkna noggrannheten på en kommersiell intraoral scanner. Material och metod.

Introduction: Pregnancy, obesity, aging and certain diseases are examples of conditions thataffect the body, its constitution and composition. Simpler methods to estimate bodycomposition are needed to complement more advanced traditional methods to better identifythe health status without sacrificing accuracy and precision.Objective: To validate the results of body composition from bioelectrical impedancespectroscopy (BIS) against results from the study reference method, dual energy X-rayabsorption (DXA), in overweight and obese lactating women after childbirth.Method: The design of the LEVA-study (Lifestyle for Effective Weight loss during lactation)consisted both intervention and longitudinal follow-up, which gave the opportunity tovalidate the absolute values (accuracy) and the ability to detect changes (precision). Themean difference between methods was tested statistically by paired t-test. Bland-Altman plotsused to examine the degree of agreement between BIS and DXA, but also distribution andany systematic differences. Association between methods was measured by using Pearson´scorrelation coefficient.Results: Between BIS and DXA, absolute measurements of the variables fat-free mass (FFM)and fat mass (FM) showed a statistically significant difference (p < 0.001).

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
