?Stå inte och häng!? En undersökning av bemötandepolicyer på svenska folkbibliotek

The aim of this Master?s thesis is to survey what personal encounter at the library can signify, and to examine Swedish public libraries? policies for personal encounter. The posed questions are: What does personal encounter at the library signify? How are users and library staff represented in the collected policies? What do the policies say about digital encounter? 290 e-mail queries were sent to Swedish public libraries in May 2010. Of 140 responses, 107 stated that they did not have a written policy on personal encounter.

Studie samt reglering av luft- och massflöde för en barkpanna

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

Varför läxor? : En studie om några mellanstadielärares tankar om och syfte med läxor

The aim of my study is to get an idea of how some teachers use homework, what they consider a good homework is, and what considerations they take to the students' home circumstances. I have made a qualitative interview study with four middle school teachers. The results of my study show that teachers can flip the classroom and use so-called preparatory tasks. The time saving aspect is a strong reason they choose that model. That students are able to practice their own responsibility and perform meaningful homework seems to also be in focus, but the biggest reason they use flipped classrooms seems to be because it is a more equivalent homework then traditional homework, and that students and their guardians also appreciate the flipped classroom model as they become more involved in their children's schoolwork..

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.

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.

Är den svenska valutan anpassad för en långsiktigt hållbar utveckling? : ? vilka brister finns och hur kan de åtgärdas?

Money by definition is always a subjective human creation. Because of this it is unavoidablethat the physical and mental structure of a specific money system will have an effect on thesociety where it is circulating. With this fact as a starting point, the thesis is analysing whetherthe Swedish national currency, the crown, is consistent with a sustainable development. Theaim of the analysis is to: (a) identify the major shortcomings of the infrastructure of the crownin relation to its ability to support a sustainable development, (b) evaluate what possiblesolutions there are at hand to adjust for the shortcomings. The method used is purely based ontheoretical analysis, with emphasis on abstraction and causal simplicity.In a modern society, money is not only circulating as coins and bills, but also as digital assetstransferred directly between bank accounts.

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.

Identifiering av röjningsbestånd med hjälp av flygburen laserskanning

Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.

Lärande datorspel som kognitivt stöd för språkinlärning i förskolan : En granskning av datorspelet Klura ut

Digital spelbaserad inlärning handlar om användningen av spel i undervisningssyfte. Få forskare har undersökt dessa spels inverkan på förskolebarns språkinlärning, speciellt med situerat lärande som utgångspunkt. I denna studie har detta gjorts genom en kvalitativ studie när datainsamlingen består av en teoretisk bakgrund, intervjuer och observationer. Studien har sin utgångspunkt i de teoretiska ansatserna situerad kognition, distribuerad kognition samt embodiment. Genom att triangulera fynden från intervju, observation och den teoretiska bakgrunden får studien fram ett resultat och svar på studiens frågeställning.

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..
