Utmattning av vägbroar i armerad betong enligt eurokoder

Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.

Hur hanterar institutioner en miljö med blandade Operativsystem?

The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis..

Uppstart av Totalt Produktivt Underhåll på Tour & Andersson AB

In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM). Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.

Forskares roll i säkerhetisering - att bygga broar eller elfenbenstorn : En teoriutvecklande studie av Köpenhamnsskolans säkerhetiseringsteori med fokus på "bridging the gap" mellan forskare och policyskapare

Studien syftar till att undersöka forskares upprätthållande av säkerhetiseringen av Irans kärnkraftprogram och hur detta påverkar deras roll som potentiella policyskapare. Studien ämnar vara teoriutvecklande genom att definiera Köpenhamnsskolans aktörsroll inom säkerhetiseringsteorin på ett mer nyanserat och precist sätt. Studien går igenom olika perspektiv inom debatten kring ?bridging the gap? mellan teori och praktik och använder Köpenhamnsskolans säkerhetiseringsteori som analytiskt ramverk vid analysen av det empiriska materialet. Studien analyserar artiklar skrivna av amerikanska forskare i amerikanska tidskrifter och undersöker hur och om dessa upprätthåller säkerhetiseringen av Irans kärnkraftprogram.

Tonala skillnader mellan ett tryckande stall och ett limmat stall. : -hos en bouzouki

SummaryI have a great interest in bouzoukis and since I, during my education in guitar making, mainly have focused on building bouzoukis and other traditional folk instruments, I have chosen the bouzouki as the object of my degree project.In connection to the making of these instruments, I started to consider the construction of the bouzouki and why the bouzouki has such a characteristic sound.One of my theories is based on the fact that most bouzoukis are made with floating bridges instead of glued pinbridges. Do these types of bridges differ from each other tonally and if so, how much and in what way?To receive answers to my questions, I have built two identical bouzoukis with different types of bridges, one with a glued pinbridge and one with a floating bridge. I have been very precise in the making of these instruments, giving them the exact same dimensions and using material from the same piece of wood. This to make sure that the instruments should be as exactly alike as possible.After finishing the making of the bouzoukis, I arranged for a sound test where I let musicians play and listen to the instruments.

Underhållsfria material i broöverbyggnader : Fördelar ur kostnads- och miljösynpunkt vid användning av rostfritt stål och direktgjuten betong

En stor del av Trafikverkets budget går till att reparera och underhålla våra broar. Underhållsåtgärder orsakar också trafikproblem med stora miljöutsläpp och samhällskonsekvenser som följd. Eftersom broar vanligtvis dimensioneras för en lång livslängd på 120 år är det viktigt att planera för långsiktiga lösningar och förutse konsekvenserna av kommande underhållsåtgärder. Genom att använda mer underhållsfria material finns möjligheten att minska kostnaderna och koldioxidsläppen.Målet med examensarbetet är att ta reda på hur stora besparingarna är genom att svara på frågan: ?Vilka fördelar erhålls av att använda mer underhållsfria material i broöverbyggnader ur kostnads- och miljösynpunkt??.

Lärare och skolbibliotekariers samarbete : Utifrån TLC-modellerna

This two year masters thesis is written in the scientific field of library- and information science. The purpose of the study is to investigate the collaboration between teachers and librarians in different types of school library organisations. Two school libraries with only the school as a target group, two integrated public- and school libraries, one school library division and one public library that provides the school with school library services has been studied. The study takes place in Uppland.The theoretical framework used is based on Montiel-Overall and her four models of collaboration: coordina-tion, cooperation, integrated instruction and integrated curriculum. The first research question focuses on the col-laboration between teachers and librarians based on each of the TLC-models.

Biblioteksutvecklingen i Göteborgs södra skärgård, Styrsö folkbibliotek, 1943-1976

The purpose of this thesis is to describe and analyse the road towards a modern library in the southern archipelago of Gothenburg between the years 1943 and 1976. The archipelago consists of about thirty smaller and larger islands, of which seven are inhabited throughout the year. Styrsö and the surrounding islands composed a municipality of their own until 1973. In January 1974 it became a part of the municipality of Gothenburg, this is also the year when the only bridge in the archipelago was ready to be taken into use, between Donsö and Styrsö. There is no bridge between the mainland and the islands.

Operatörsunderhåll : Ett examensarbete om att använda 5S till hjälp för att förbättra operatörsunderhållet

As the final course in the education ?University Diploma Programme for Process Operators? there is a thesis in cooperation with a company required.This thesis is about operator maintenance and 5S made at Metsä Board in Husum.In this report you can read my opinions and conclusions based on literature studies and the interviews that have been made with the staff at PM6 (the paper machine).I chose to focus on the theory of lean, 5S and operator maintenance because it covers the area of this thesis.The operators shall do their rounds to make sure that the equipment works fine. They shall also write down things that they notice in a checklist. This is not done as it should be and the question is: can this be solved by using 5S?My conclusion of this thesis are:Better review of the task so that everyone is involved.

Ersättningsmodeller för ballasttransporter : vid anläggning och underhåll av skogsbilvägar

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

Civil-militära relationer i komplexa fredsinsatser ? ett organisationsperspektiv

The response to many on-going or emerging conflicts since the beginning of the 21st century has been different forms of multinational complex peace operations. Civil-military relations are a commonly studied field that traditionally has its focus on nations. This study intends, in the context of organisations, to test the correlation between a civil-military approach and outcome in complex peace operations. A hypothesis has been deduced from researcher Robert Egnell?s theory on complex peace operations, that states that: UN peace operations with an integrated civil-military approach are more successful in achieving their goals than peace operations with a divided approach.
