Studieval och yrkesval : En jämförande studie om elevers val på Teknikprogrammet respektive El- och energiprogrammet.

The purpose of this study is to understand the factors that are affecting students at the Technology and Electricity- and energy programs in their choice of studies and vocation. The study is a comparative case study and quantitative method has been used in the form of questionnaires. The result shows that students do not like to be affected by another person but believes that they themselves have made their choice. Interest turns out to be the biggest influence factor of choice for both students at the Technology and Electricity- and energy program. For Electricity- and energy students have also access to work had some impact.The parents' education level was higher for Technician students and their parents worked with occupations requiring university degrees.

Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality

Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.

Knapptryckardemokrati : Om synsätt på IT-stödd demokratiförnyelse

With the increased significance of information technology (IT) in today?s society the term ?electronic democracy? (e-democracy) has gained much importance within the democracy theory. Naturally, there are several competing views on how the technology should be used for democratic purpose. One aspect of this is the somewhat revitalized claim for direct democracy in accordance with the hypothetical opportunity to finally realize it as a democratic system. The ideal of direct democracy combined with the almost total credence in the potential of technology constitute the idea of a ?push-button democracy?.

Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik

Implementering av Virtuellt Byggande i byggprocessen : Fallstudie av NCC Construction Sverige AB

Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.

Set Based Concurrent Engineering : En undersökning för Scania CV AB

This Master thesis has been carried out at Scania CV AB in Södertälje, in collaboration withKTH, The Royal Institute of Technology, Stockholm. The focus of this Master thesis isSetBased Concurrent Engineering(SBCE), with the purpose of answering the questions: what isSBCE, how does it work, and for what purposes is it applied.It was early established thatSBCE is often included as a part of Lean product development,which in its turn is often related to Toyota?s way of working. TheSBCE method includesworking with multiple solutions in parallel, eliminating weak alternatives throughout thewhole process. In opposite to a conventional product development process, where it iscommon one at an early stage tries to identify and choose the most promising alternative.Despite the appearance ofSBCE as a resource consuming method, figures from Toyotaindicates the opposite, thatSBCE is in fact a very effective way of working compared to othermore traditional methods.The process of this Master thesis was divided into three phases.

IT-användandet i byggbranschen har banat väg för nya, effektivare arbetssätt och det finns visioner om hur det ska fungera. Syftet med vårt examensarbete är att ta reda på byggbranschens användande av, och vision om BIM. Vad är BIM ? Building Information Model?Kort beskrivet är BIM en modell där all information för ett byggprojekts hela livscykel kan hanteras. BIM förenklar det fortlöpande arbetet genom hela byggprocessen genom att tillhandahålla information om projektet som är relevant, uppdaterad, integrerad, fullt koordinerad och av hög kvalité.

KBE I PRODUKTUTVECKLING PÅ SCANIA : En undersökning av potentialen i CATIA Knowledgeware

Övergången från CATIA V4 till CATIA V5 innebär nya möjligheter för konstruktörerna på Scania att arbeta med Knowledge Based Engineering, KBE, för att effektivisera och kvalitets-säkra sitt arbete. Då CATIA V5 är en ny plattform som innehåller verktyg med samlingsnamnet knowledgware, för att bygga in kunskap i modeller ville Scania undersöka potentialen i att arbeta med KBE, och hur detta skulle kunna ske på Scania. Vid traditionell produktutveckling tas en helt ny artikel fram vid behov och ofta innebär detta att arbete som tidigare utförts, görs om igen. Syftet med arbetet är därför att undersöka huruvida KBE i CATIA V5 kan erbjuda möjligheter att återanvända kunskap från tidigare arbete och samtidigt kvalitetssäkra denna, samt utreda vilka knowledgewarelicenser som i så fall kan vara lämpliga för Scania.För att göra detta har en litteraturstudie genomförts för att undersöka vad som har gjorts inom området, och även en intervjustudie har utförts inom R&D på Scania. Vidare har sakkunniga på Linköpings Universitet och Tekniska Högskolan i Jönköping intervjuats.

The theory chapter is based on different strategies that companies have to or can apply to get ahead, stay or survive in a hypercompetition.

En jämförande studie av Svenskt Vattens och CAC:s syn på HACCP-processen, En utvärdering och ett praktiskt tillämpande av Svenskt Vattens "Handbok för egenkontrollprogram med HACCP"

Denna rapport, En jämförande studie av Svenskt Vattens och CAC:s syn på HACCP-processen, En utvärdering och ett praktiskt tillämpande av Svenskt Vattens Handbok för egenkontrollprogram med HACCP, skriven av Anna Järvegren Meijer (handledd av Kenneth M. Persson, professor vid Teknisk Vattenresurslära, Lunds Tekniska Högskola och Anne Levin, konsult på SWECO VIAK, Malmö) behandlar kvalitetssystemet Hazard Analysis and Critical Control Points (HACCP) och fokus ligger på tillämpning inom beredning och distribution av dricksvatten.Rapporten består av tre delar. I den första redovisas HACCP-processen och de arbetssteg som Codex Alimentarius Commission har tagit som praxis. Här jämförs också Svenskt Vattens syn på HACCP i Handbok för egenkontrollprogram med HACCP med just CAC:s. Det konstateras att skillnader finns då Svenskt Vatten har valt att inte följa CAC:s praxis till punkt och pricka utan utformat arbetsgången annorlunda.Den andra delen av rapporten handlar om hur användarvänlig Svenskt Vattens handbok är i praktiken.

Infiltration av lakvatten från specialceller i bioceller -en effektiv metod för att förhindra spridning av metaller

Deponering är en metod som sedan länge använts för att behandla avfall. Metoden är dock kopplad till en rad miljöpåverkande faktorer, varav produktion av lakvatten är en. I lakvattnet finns bland annat lösta näringsämnen och metaller och dessa kan ge negativ påverkan på ekosystem om de sprids i miljön.Det här examensarbetet syftar till att besvara frågan om metaller i lakvatten kan retarderas genom att lakvattnet från en specialcell infiltreras i en biocell. För att besvara frågeställningen har mätvärden för ett antal kemiska parametrar analyserats på en deponeringsanläggning som ligger i Malmö och bedrivs av SYSAV.Arbetet avser även svara på frågan hur hårt biocellen kan belastas i fråga om hydraulik. Därför simuleras de förväntade uppehållstiderna av vatten i biocellen vid olika infiltrations-hastighet och porositet.För att ge resultaten tyngd har en litteraturstudie avseende deponering, hydrologi och hydraulik, lakvatten och metallers mobilitet i mark och vatten gjorts.Resultatet från litteraturstudien visar bland annat att lakvatten produceras genom att nederbörd perkolerar genom avfallet.
