FE-modellering av hjullast på sandwichpanel
This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.
Turkiet och EU : En studie i turkiska medborgares förhållningssätt till det europeiska integrationsprojektet
Euro barometer surveys show quite an astonishing change in Turkish opinion towards European Union. In 2004, 73 % of the population considered EU as a good thing. In 2008, only 49 % were of the same opinion. At the same time, skepticism towards European integration is explained differently in earlier research. Some scholars claim that partisanship may explain attitudes of citizens better than ?cost and benefit? approaches.
Analys och modellering av ljusbåglängdsregleringen i pulsad MIG/MAG-svetsning
This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.
Folkbibliotek och TV-spelande ungdomar en studie i bibliotekariers attityder och värderingar när det gäller ett nytt medium på biblioteket
The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.
Possibilities for, and attitudes towards, a potential reintroduction of wild forest reindeer Rangifer tarandus fennicus Lönn. to parts of Sweden.
AbstractThe wild forest reindeer is a subspecies of the reindeer. Wild forest reindeer earlier had awide distribution range in Sweden, but it was extinct in the middle of the 19:th centurybecause of extensive hunting. In Finland, the w.f.reindeer was extinct a few decades later bysimilar reasons. Later they migrated back to the eastern parts of Finland in the middle of the20: th century. Around 1980, the w.f.reindeer was actively rentroduced to western Finland,and there the population has had a positive development.
Personer med Aspergers- och autistiskt syndroms förutsättningar till delaktighet i samhället
Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.
Det handlar om träd. Ett utforskande mönsterprojekt för textil
This is a pattern project for textiles, with main purpose to develop and challenge my design process and to experiment with a mix of different printing techniques. The goal of the project was to create three textile individuals as representatives of my experiments, inspired by natural surfaces.The world of fashion have been an inspiration and has been the model for these textiles, with its powerful and playful patterns. With the world of fashion as a model, I also chose to work with the materials habotai silk and silk velvet. The qualities of these materials has also been influential in my design language.The work has been very focused on experiementation and exploration, and resulted in three printed fabrics that I have chosen to call Björkalm, Lindstam and Lavbädd..
"Du får titta i min bok!" : Fem förskolelärares tankar om barnbibliotekens funktion i barns tidiga läs- och skrivförmåga.
This study aims to examine preschool teachers' thoughts about the child libraries functions. The purpose is to highlight preschool children's early read and writing skills, before they even can read and write, which is a theory called emergent literacy.This is made by conducting five qualitative interviews, with the intention to investigate how the preschool teachers think about the cooperation and the function of the child library, partly for their own work with the children and partly for their organization. By using a tablechart which shows each preschool teachers mostly common thoughts in the interview and by using a model based upon Harrysson and Joelsson (2006) model, which shows the functions of the public library in the society. The results of the study are presented in the four categories of the model which are; to borrow, to learn, to ask and to find, to reside. These are functions that the preschool teachers see with the library, for their work with the childrens' early literacy.
Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL
This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.
Utbredning av markvibrationer och stomljud från järnväg : Undersökning och anpassning av beräkningsmodell
The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..
Jämlikhet, frihet och kulturell mångfald - en studie om normativa ideal och kulturella rättigheter i offentliga utredningar
To create fair conditions between the majority and minorities in a cultural diverse society poses a challenge for both the makers of government policy and the political theorist. The aim of this thesis is to examine the Swedish government official reports concerning integration and minority rights, with a special interest in values and cultural rights. As a methodological tool a theoretical model that classifies cultural rights is developed and the three normative doctrines lockean libertarianism, comprehensive liberalism and multiculturalism are distinguished from the discussion about how politics ought to be in a multicultural society. Through this perspective rights and values in the official reports are identified and analyzed. The result shows three different standpoints in the reports concerning which cultural minority group they are discussing.
Närståendes uppfattning av den äldres vårdbehov i samband med samordnad vårdplanering
Introduction: The population of Sweden has during the last century doubled. An increased live expectancy results in an older population and the share needing medical care increases. Demographic and political changes in developed counties have resulted in changed demands on the care of the elderly. The elderly are discharged from hospital earlier and this results a significant responsibility on the elderly themselves and their relatives. Often the relatives are engaged in the elderly?s health problems, care needs and the future consequences the current situation results in for the elderly and the domestic life.
Han och hon möter vi och dom ? den universella välfärdspolitikens akilleshäl : En studie av kön och ras i svensk förvaltning
Gender politics in Sweden is considered unique because gender policies (jämställdhet) are integrated into national politics and politicised both in the public and the private sphere. The Swedish case is therefore considered a role model by many feminist scholars.This view has been criticised by both post modern feminists and public administration scholars. Critics imply that the increased immigration and more heterogeneous population have led to a new challenge for state institutions. The Swedish model, with its universal welfare solutions, lacks the ability to recognise differences within groups. Universal solutions that treat everyone the same is no longer the most just way to treat people.The growing use of goal orientation in Swedish public administration has increased the civil servants discretion in the implementation process, and thereby the space for differentiated treatment.
När bok blir film? : En jämförande analys av boken och filmen Catch me if you can
AbstractTitle: When book becomes film... ? a comparative analysis of the book and film Catch me if you can (När bok blir till film?En jämförande analys av boken och filmen Catch me if you can)Number of pages: 46Author: Majlinda JunikuTutor: Amelie HössjerCourse: Media and Communication Studies CPeriod: Autumn term 2007University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: To study what model of dramaturgy belongs to the film Catch me if you can and to see what has been crossed out, altered and added from the book so the narrative will fit this model.Material/Method: The film Catch me if you can and the book with the same name has been used to analyze the differences between them. I have divided the differences into three categories: Crossed out, Altered and Added. In the analysis section these have been presented in each section of the film.Main results: Catch me if you can is definetly a film made with the design of the Anglosaxon model, mostly because of its timestructure and that it portrays an action and not just a condition which is normal in the epic-lyric model.
Demografisk sammansättning samt beteende hos medlemmar i panel
The use of marketing research panels are a more and more frequently used source of information for studies within many different branches. The purpose of this report is to investigate the demographic composition of panels and compare it with the population of Sweden, a possible change in behaviour of respondents, and if the source of recruitment is the cause of possible differences in study results. The study was commissioned by Norstats Linkoping office. Sources for the data material include Norstat?s recruitment process and their two main panels with different recruitment sources.
