Oförstörande provning in-line : Säkerställande av produktionskvalitén vid gjutning av cylinderhuvuden
För att unvika onödiga kassationer inom fordonsindustrin satsas det mycket på att få fram ?rätt kvalité? på komponenterna från början. Dagens metod är slumpmässiga förstörande tester där endast ett fåtal komponenter testas och förstörs. Denna metod blir dyr i längden på grund av att produkten förstörs och det går inte att följa upp med ytterligare analyser. Porer och inneslutningar vid gjutningen av cylinderhuvud och är ett vanligt problem i fordonsindutrin och när inte varje komponent kan testas och kvalitetssäkras på ett snabbt och effektivt sätt generar det kostnader i både tid och pengar.Målet med detta examensarbete var att utreda om RAM (Resonant Acoustic Method) kan upptäcka dessa porer och inneslutningar med en storlek mellan 1?5 mm i cylinderhuvud från Scania och även undersöka om RAM kan sättas in direkt i produktionslinorna.Med RAM gjordes fem tester per objekt med tre stycken mikrofonpositioner och tre stycken excitationspunkter och med en upplösning på 1,5 Hz.
Riskbedömning av miljö- och hälsoeffekter efter järnhanteringen i Strömsbergs bruk
Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the contaminated sites. This builds on the ?Method for Inventories of Contaminated Sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.
Vårdprogram för Österby bruks köksträdgård :
Svenska (engelska se nedan)
Detta examensarbete är ett vårdprogram över Österby bruks köksträdgård. Österby bruk är beläget i norra Uppland cirka fem mil norr om Uppsala. Redan på 1500-talet började järnindustri växa fram på Österby. Österbys järnindustri kom att pågå fram till nedläggningen av Österbyverkan 1983. Dagens köksträdgård tillkom i och med den omgestaltning av hela herrgårdsanläggningen som startade på mitten av 1700-talet.
Duende : En analytisk studie av Federico Garcia Lorcas estetiska begrepp och dess inverkan på Bruno K. Öijers Trilogin
This paper examines how the Swedish nationalistic political party Sverigedemokraterna communicates regarding the crisis they experienced when the Swedish newspaper Expressen published a few video clips of three, in that time, highly important party members that got in an argument after a late night of drinking. Two of the party members were at the time of the publication the members of the Swedish parliament and all of them had important senior positions in the party. In the argument one of the party members used abusive, offensive, sexist and racist language while all acted threatening and even armed themselves with iron bars from a nearby construction site.The aim of this paper is to examine how the party Sverigedemokraterna conducts their crisis communication, if they apologies and the fashion of the apology. A press conference with the party leader and the most active user of abusive language and also an interview with the second member of parliament who is involved in the argument are studied. The rhetorical arena is used to describe and pinpoint the most important stakeholders in the crisis.
Gravar i stenskepp : Osteologisk analys av brända och obrända ben från skeppssättningar på Gotland
In this study bone material from six stone ship settings and a total of seven deposits of bones from two sites on the island of Gotland have been analyzed. Four ship settings from the burial site at Gålrum in Alskog parish and two from Tängelgårda in Lärbro parish. The ships contained both cremated remains and inhumations. Human remains were identified in five of the analyzed ship settings and a minimum of six individuals was identified in total. Animals were found in three of the ship settings, where one of them contained only the burned remains of a dog. Two of the ships contained inhumations, one in Gålrum and one in Tängelgårda.
Språket vår Järnbörd : Språket spelar roll
In this paper I make an analysis of the play Järnbörd (By burning Iron) written by the swedish author Magnus Dahlström. In this play all the characters has committed horrible crimes wich they easily describes the violence. The starting-point of my analysis is the text itself and not any stage-setting. The reason for this is that I find it interesting to see what can be found in the text only. I investigate if the language itself can tell something.Furthermore I discuss Magnus Dahlström´s literary language and if he has any distinguishing quality, and if so what it may be.
Robotiserad produktionsanpassad magnetmontering för vågkraftverk
This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work. This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner. The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month. According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .
Civila musikkårer i landskapet Värmlands bruksorter : Betydelsen av faktorerna ekonomi, rekrytering, musik och kulturskolan, samt samverkan med studieförbunden för musikkårernas överlevnad
This bachelor thesis is about civilian marching bands in the province Värmland industrial communities, with a focus on Degerfors, Edsvalla, Gruvön, Nors, Slottsbron, and Vålberg bands. Degerfors, Gruvön, and Slottsbron bands are three corps that still operates concerts and performances. The other three unions are defunct.In Värmland, there were many mills that were operating well into the 1900s, roughly speaking there were about 25 mills in various industrial areas. These mills had operations in glass, iron, and paper, each user had a band at least a brass sextet and today there are only eight bands left in Värmland. Bofors in Karlskoga, Charlottenberg, Degerfors, Dejefors, Gruvöns in Grums, Hagfors, Skoghall, and Slottsbron bands.What is the reason that so many bands have disappeared? To answer the question I have investigated the importance of four factors have had for the unions: finance, recruitment collaboration with the music and arts, as well as cooperation with educational associations.The results show a marked reduction in civil bands, from about 25 corps to eight corps today.
Vem håller i taktpinnen i krisberedskapsarbetet? - En studie av risk- och sårbarhetsanalyserna i länsstyrelserna
Crisis management planning is a relatively new policy area in the European countries. It has materialized since the fall of the iron curtain and because of the increased interest to prevent wide-ranging national emergencies. In Sweden, the county administrative board has a key obligation to perform risk analysis guidelines. This assessment involves identifying crisis, planning response to the crisis and, if necessary, confronting and resolving the crisis in the geographic area of the region. The purpose of my thesis is to examine if there are any differences in crisis management planning between the county administrative boards? risk analysis guidelines.

När världen kom till Föra : om forskningens syn på Ölands kristnande
This paper aims to give an account of, and to discuss the view-points and theories of different researchers on the christianization of Sweden, especially the province of Öland, during the early middle ages. Its purpose is to investigate how, and in what sense, their positions can be said to correspond to what we may know of the historical ?facts?. This will be possible by comparing different points of view with a study of the development in a single parish. An overall difficulty however, is the nature of the sources relating to the time in question, they are scarce or even non-existent.Part I of the paper consists of an outline of the field of research and the different theories put forward on the subject.
Potentiell fosforfrigörelse från sedimentet i Bornsjön, sydvästra Stockholm : The potential leakage of phosphorus from sediment in Lake Bornsjön, south western Stockholm
Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.
