Trycksatta huvudvattenledningar : Guide för material och schaktfria metodval vid åtgärder av vattenledningar
Detta examensarbete har utförts på uppdrag av Johan Lundberg AB som har haft ett behov av att det tas fram en guide vid åtgärder av vattenledningar. Åtgärder kan innebära nyläggning, utbyte eller renovering av en vattenledning. Syftet med rapporten är att ta reda på om ett visst material eller metod kan användas till vattenledningar, få fram för- och nackdelar med dessa material och metoder, både för installationsfasen och för driftsfasen. Detta görs ur ett långsiktigt tekniskt, ekonomiskt och miljömässigt perspektiv. Rapporten innehåller en faktadel med tänkbara material och schaktfria metoder och sju stycken intervjuer med ledningsägare har genomförts och en sammanställning av dessa intervjuer presenteras i kapitel 5.3.
Program- och projekterings anatomi ? en studie av byggprogrammets program- och projekteringsskede
Program- och projekterings anatomi? en studie av byggprogrammets program- och projekteringsskedeStudien belyser och lyfter upp byggnadsprocessens, idag kanske viktigaste fråga, nämligen industrialiseringen av byggprocessen och de möjligheter som följer med det nya sättet att föra en byggprocess. Studien omfattar program- och projekteringsskedet och dess syfte är med andra ord ett försök att skapa en mer förädlad byggprocess, att kunna identifiera olika störningsmoment under dessa två skeden, samt att minimera och om möjligt eliminera störningsmomenten i dessa med hjälp av fungerande informationsteknik.I samarbete med Peab i Helsingborg har vi gjort en enkätundersökning på två referensobjekt, Polishuset samt Tingshuset, utifrån vilken vi tagit reda på vilken ställning de olika aktörerna har gentemot byggprocessen och varandra, samt var, varför och vilka störningsmoment som uppstod i byggprocessen.Resultatet visade närmast likadana faktorer hos de olika aktörerna och exempel på detta är att:? hälften av aktörerna önskar bli inkopplade i ett tidigare skede av processen? det uppstod störningsmoment mellan de olika aktörerna? störningsmomenten orsakades oftast av dålig planering och tidsbrist? utveckling/förbättring borde göras inom kommunikationen mellan parterna och inom informationsteknologinVidare beskriver studien utformningen av standardiserade byggsystem och tekniskt plattformstänkande samt montagebyggande med högförädlade komponenter, där vi kom fram att Peab har långsiktiga planer och att företaget inom en kort framtid kommer att vara ledande inom området.Studien sammanfattar slutligen de faktorer som tros behövas för att en industriell byggprocess skall lyckas i framtiden..
Utveckling av Höggeröds fritidshus. En fråga om bevarande och modernisering
Höggeröd på nordöstra Orust är ett vackert fritidsområde med en tidstypisk karaktär från sextiotalet som är värd att bevara. Ett problem som uppstått på senare år är att husägarna vill flytta in permanent i sina fritidsstugor och bygga ut dessa till större och mer funktionella villor, men detta godkänner inte detaljplanen. Samtidigt finns en önskan om att kunna lösa detta ändå och göra alla delaktiga parter nöjda. Syftet med rapporten är att uppmana till en fördjupad diskussion om Höggeröds fritidshusområde och frågan om hur dessa skall utvecklas och samtidigt bevaras. Frågan om vilka krav och lagar som gäller kring ombyggnationer har även besvarats för att kunna göra ett så bra underlag som möjligt.För att kunna bevara detta kulturarv så kommer ett underlag till en bevarandeplan att tas fram med hjälp av den här rapporten.
DJUR : Djurkroppar som material i konst, hantverk och design
Detta examensarbete behandlar fenomenet att använda djurkroppar som material. Studiens syfte är att undersöka fenomenet döda djur och djurkroppar i konst, hantverk och design, och lyfta fram på vilket sätt döda djur används och hur användandet kan tolkas och förstås. Teorin belyser relationen djur och människa ur historiskt perspektiv, hur djur framställts inom konsten, samt den etiska aspekten. Metod och material består i en analys utifrån texter och medier, och en kvalitativ intervju med Märta Mattsson, som skapar smycken av främst insekter. Studien visar på att djur har varit symbol för många olika saker som mod, tapperhet, häxkonst och erotik.
Effekter av ett informationsintensivt material- och produktionsstyrningssystem
We were assigned to do this master thesis by Husqvarna AB who at the time for this thesis just had implemented a new material and production planning system called Replenishment system. Husqvarna AB wanted us to examine the effects of their new planning system to see if it was profitable or not. Husqvarna AB had for a time considered their delivery and supplier service to bee their biggest problem and they wanted to solve this problem by improving the communication with all involved actors in the logistic chain, which they hoped would result in a better mix of products in their warehouses. The aim of this report was therefor to analyze eventual effects for Husqvarna AB when changing from a traditional material- and production planing system to a more information intensive one. The result of this report showed effects on decreasing administrational routines and improved flexibility and lead-times.
Hur uppnår vi god inomhusmiljö i förskolan idag?
Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.
...de bultades till bättring : till frågan om Sveriges kristnande
The written sources concerning the process of christianization in Sweden has for a long time been limited to two main texts, Rimberts vita of St. Ansgarius and Adam of Bremen´s History of the bishops of Hamburg. This is due to a rigid source criticism in the beginning of the 20th century, which put other material ? in particular the norse sagas ? out of consideration. The last twenty years however, new questions have been raised concerning the christianization, partly because of new archaeological findings, new interpretations of the significance of runic stones and the recent debate about the formation of the Swedish medieval kingdom.
Statushantering i Virtual Map med ledningssamordning i BIM
For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

Delat ansvar för ett enat Sri Lanka: asymmetriska relationers påverkan på fredsprocessen
Since 1983 the people of Sri Lanka has endured an ongoing Civil war, however the intencity has varied over the years. The aim of this theses is to examine what influence the asymmetric relationship between the Sri Lankan goverment and the Liberation Tigers of Tamil Eelam (LTTE) has on the process of negotiating a solution to the civil war. I am also examining whether the asymmetical relationship has changed over time and if these changes have had any effect on the process.To analyze the asymmetries I divide them into material and non-material. I measure the material asymmetries in economic and military resourses, and to measure the non-material I use indicators such as commitment, alternative, controll and legitimacy.The results show that the asymmetrical relations between the parties in Sri Lanka have changed since the 1990s. Factors like 9/11 and the recurrent suicide bombings by the LTTE has had a great influence on the singalese-tamil relationsship.
?Våra långväga vänner": folkbibliotekarierna och de ensamkommande barnen
Purpose: The purpose of the study reported in this thesis is to addto the knowledge concerning what public librarians do to meet theneeds of unaccompanied asylum-seeking minors, thereby helpingthem to develop and establish themselves in a new environment.What tasks, activities and tools do the librarians have at theirdisposal? What problems do they encounter? What values, normsand attitudes guide their work? Method: The thoughts andexperiences of six public librarians have been captured throughqualitative semi-structured interviews, the result of which has beenthematically analysed using notions of social capital and socialexclusion. Findings: Unaccompanied asylum-seeking minors facea number of challenges which the public library with its librarians,collections and various activities can assist in coping with byproviding the children with opportunities to increase their socialcapital and decrease the risk of social exclusion. Researchlimitations: It has for several reasons proven difficult to studyunaccompanied asylum-seeking children as a distinct group, whichis why this study also uses material that deals with refugees as awhole. A significant amount of the latter are undeniablyunaccompanied minors, an especially exposed and vulnerable typeof refugees.
Utveckling Ulricehamn- om stora förändringar i en liten stad :
The purpose of this thesis is to inquire how a small town can be affected by some planned changes in the physical structure of the town, and how its inhabitants can benefit from those major changes. The town in question is Ulricehamn, and of the four projects considered, two concerns infrastructure. A new railway and a new locality for the major road, today passing through Ulricehamn. The other two projects are run by the local authorities, that is the planning of a modern town park by the lake, and a new public building for cultural purposes. There are no guarantees that any of the four projects will ever be realized, but in the process with this work, they have been considered as already a fact.
