This is a diploma thesis executed as a part of the examination of the educationalprogram Building engineer ? Construction management at Halmstad University. The aim of the thesis is to compare and evaluate conventional open-cut pipe-laying withhorizontal directional drilling. The thesis includes a comparison of the economic,environmental and time-based aspects of both methods and discusses which factorsthat determine the optimal choice of method.The study is mainly based on previous studies regarding the subject and oninterviews with professionals from the industry.A fictional project with five realistic cases of pipe-laying scenarios was compiled,sent to different companies for calculation, evaluated and compared. Our conclusionregarding when it?s suitable to use which method is entirely dependent on thespecific project.

Vägbyggnadssektorn står inför ett stort steg i och medövergången till att projektera i 3D. Idag finns programvara för 3Dprojekteringfrån flera leverantörer och stora mervärden finns att erhålla föralla parter i byggprocessen. Studien har genomfört med hjälp av enlitteraturstudie men inventering av programvara, en fallstudie av ettvägbyggnadsprojekt samt en enkätundersökning med aktiva vägprojektörer.För att övergå till ett ökat användande av 3D-modeller krävs att intresset ochkunskapen ökar genom hela byggprocessens aktörer. Detta bör ske genom enutbildning hos projektörer som sedan visar de mervärden som en 3Dprojekteringger för entreprenör och beställare..

How accessible is the city? Is there more factors than merely the strictly physical that affect how accessible the city is perceived? These questions are the starting point of this study. The greatest emphasis, in this study, is placed on the perceived parameters that affect us humans when we move in our cities. Experiences and internal images can change our behaviour and prevent free movement in the city. The result from this study shows that a city can not be seen as fully accessible unless both the physical and the perceived accessibility are fulfilled.

The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks.

The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.

As a result of the Civil Protection Act, there is an imperative for Systematic Fire Preventive Measures, SFPM. SFPM can be divided in two parts: organisational preventive measures, and documentation of fire preventive measures. The manner in which SFPM is to be conducted is similar to that of the environmental management system ISO 14001. This report provides suggestions how to integrate SFPM with ISO 14001..

The master thesis has been constructed together with Scania, who had a wish to develop their training for newly employed design engineers. The purpose of this thesis is to examine how a company's introduction process can be shaped, as the introduction is the key to success for the individual as well as the organization. With a focus on how the productivity among newly employees can increase and how the introduction becomes meaningful to the individuals and the organization, the objective of this work is to develop concepts applicable for an introduction.The work was conducted using qualitative interviews with several different individuals at Scania and other companies. Along with the interviews a survey was constructed and sent out to newly employed design engineers at Scania to get a view of their opinions on the present training. During the first period of a job there are several factors that affect the employee based on the result from the interviews, previous research and theories.

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

This report will focus on the folkhigh-school in its general form and the role of the libraries on these types of schools in particular. A library on folkhighschools have a tendency to be forgotten and ends up being somewhere in the middle of the libraryworld and the general educational organisations. The purpose of this essay is to examine and provide general views on the different roles that a library on a folkhighschool can have, as well as looking into the unique aspects of the type of school that a folkhighschool is in terms of influencing the libraries placed there. The methodology used in this study is qualitative. Interviews have been held on three different folkhighschools in south of Sweden.

Denna uppsats är en fallstudie som undersöker samverkan för civilt försvar inom typfallet Militärregion syd (MR S). Uppsatsen bygger på semi-strukturerade intervjuer med fem länsstyrelser inom i MR S samt med två representanter från MR S. Materialet har kategoriserats utifrån en analysmodell skapad utifrån Emerson et als teoretiska ramverk Collaborative Governance. Ramverket lyfter fram viktiga förutsättningar för samverkan och visar på beroenden mellan dessa förutsättningar. Förutsättningar används för att kategorisera och jämföra svaren från länsstyrelserna och MR S samt för att undersöka hur väl dessa förutsättningar uppfylls och om de har samma syn på förutsättningarna.

Ingenjörers arbete bygger ofta på teamarbete vilket ställer krav på deras förmåga till samarbete och kommunikation. Medvetenheten om kommunikationens betydelse för ingenjören och dennes arbetsprestation har framkommit i tidigare studier och även motivationens betydelse för förändrat beteende. Syftet med denna undersökning var att undersöka vad som skulle kunna hjälpa ingenjörer inom tillverkningsindustrin att utveckla sitt kommunikativa beteende gentemot sina kollegor. En enkät konstruerades och följdes upp med 4 intervjuer. Studien genomfördes på ett internationellt företag inom tillverkningsindustrin.

Denna studies övergripande syfte är att studera hur personer som härbärgerar flyktingar ser på relationen mellan individers handlingar och hela samhällets ansvar för flyktingarna. För att uppnå syftet studeras tre mer konkreta frågeställningar; hur människor som härbärgerar papperslösa finner legitimitet för sin handling, hur de tror att andra människor i samhället ser på deras engagemang och vad de själva tycker om människor som inte är engagerade i detta. Studiens teoretiska utgångspunkt bygger på Jürgen Habermas arbete för att begreppsligöra civil olydnad. I syfte att sätta in dessa i en förståelse hur informanterna ser på sig själva i relation till samhället används också Georg Simmels teoretiska tankar om samhället utifrån hans begrepp; kristallisering, dubbel kategorisering av människor och församhälleligande (vergesellschaftung). Som metod för att samla in studiens källmaterial används en tematiskt öppen intervju. Kodning och analys genomförs med så kallad databaserad kodning, som sedan med hjälp av identifierbara underteman (antingen förbestämda eller skapade av informanterna) försöker bena ut en tankestruktur hos informanterna som kan besvara på studiens frågor.Resultatet av studien visar att legitimeringen har två delar. En är att de bistår med akuta åtgärder som exempelvis tak över huvudet för människor i nöd, den andra är att de vill ändra "systemet" på längre sikt.  När det gäller den andra frågan, menar informanterna att de i många fall beskrivs som hjältar av andra. Den sista frågan kan delas upp i två delar.

This essay will try to explain and compare the different development steps which Croatia and Bosnia-Herzegovina have taken after the war. How could countries with such similar backgrounds develop in such different ways? By analyzing and comparing the two countries the purpose was to examine how these countries which had so much in common could develop in so different ways. My two questions are: What similarities and differences are there between the development which Bosnia and Croatia have taken after the war? Why have Croatia succeeded and not Bosnia?My analysis showed that the main reason to the difference between these countries was that Bosnia is divided; all ethnic groups in Bosnia only consider what's best for their own ethnic group and not what's best for the country. Croatia however has expelled the Serbs which made it easier for them to have a succesfull democratic development. .

abstractThe aim of this essay is to try to convince the reader that relativism and postmodernism (the latter implying the former, but not the other way around) can be reasonable methods for the social sciences, rather than the irresponsible play of ?extremes? theories of this kind sometimes are made out to be.The intention is to do this by way of the later Wittgenstein, the philosophy of whom is the foundation for what is termed relativism and postmodernism in this essay (definitions of a kind that are here claimed to be missing from the discourse of the social sciences). The essay also contains an empirical presentation/analysis, displaying the Wittgensteinian theory through an aspect of the American Civil Rights movement of the 1950s and -60s..

Syftet med denna studie har varit att ta reda pa? vilka samha?lleliga faktorer som initierade det egyptiska upproret. Enva?ldsha?rskaren Mubarak hade styrt landet i 30 a?r fram till revolten 2011.
