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.

Outsourcing en fråga om överlevnad?

En väsentlig fråga hos textil- och klädindustrin (TK-industrin) har alltid varit om de skall utföra arbetet själv eller köpa in arbetet. TK-industrin använder sig av outsourcing på grund av att de inte själva klarar av att sköta verksamheten på ett tillfredställande sätt eller att man helt enkelt väljer att inte utföra arbetet själv. De främsta motiven till att outsourca är att företaget vill uppnå kostnadsbesparingar och fokusera på kärnverksamheten. TK-industrin är unik och frågan är om det främsta motivet är kostnadsbesparingar eller finns det andra motiv såsom fokus på kärnverksamhet, flexibilitet eller bättre kvalité som är huvudmotivet till outsourcing.Vårt syfte med uppsatsen är att genom intervjuer undersöka varför TK-industrin använder sig av outsourcing och vilka effekter det ger. Uppsatsen syftar även till att ta reda på hur specialiserade logistikföretag kan förbättra för företag inom TK-industrin.

Deduplicerings påverkan på effektförbrukningen : en studie av deduplicering i ZFS

Uppsatsen beskriver arbetet och undersökning för hur deduplicering i filsystemet ZFS påverkar effektförbrukningen. En större mängd redundant data förekommer i centraliserade lagringssystem som förser virtualiserade servrar med lagringsutrymme. Deduplicering kan för den typen av lagringsmiljö eliminera redundant data och ger en stor besparing av lagringsutrymme. Frågan som undersökningen avsåg att besvara var hur ett lagringssystem påverkas av det extra arbete som det innebär att deduplicera data i realtid.Metoden för att undersöka problemet var att utföra fem experiment med olika typer av scenarion. Varje scenario innebar att filer kopierades till ett lagringssystem med eller utan deduplicering för att senare kunna analysera skillnaden.

PSQS ? Power Supply Quality Simulator

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

Ergonomiska förhållanden för mjölkare i olika mjölkstallar :

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

Following on from this question, further issues arise such as: 1. How do the varying demands of the clients affect the workload of the social worker? 2.

Med brödfödan som drivkraft : En studie om att byta olja mot biodrivmedel i ett globalt perspektiv

Av två anledningar anses det som mycket viktigt att bryta beroendet av olja, naturgas och kol. Den första anledningen är de uppmärksammade klimatförändringarna. Förbränning av fossila bränslen anges idag som huvudorsak till växthuseffekten. Den andra mindre uppmärksammade orsaken är att oljan och naturgasen snart inte räcker till för att föda en allt energihungrigare värld. Utvinningen ser dessutom ut att ha nåt sin kulmen.

Eurocodes : Beräkningsjämförelser mellan eurocodes och BKR

In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.
