Bakgrund och problem: Under de senaste åren har företag ändrat grundkoncepteninom verksamheterna, genom att bara fokusera på sin kärnverksamhet.Affärsrelationer har blivit av större vikt då koncept som outsourcing tillämpas, vilkethar lett till att integrationen mellan företagen ökar. Ekonomistyrningsmetoder hardärför blivit av större intresse då företagsgränserna flyter ihop med varandra. Inombilindustrin har trycket ökat, vad gäller effektivisering och kostnadsreducering ivärdekedjor. Det kan vara de krav kunden ställt och de behov som finns för att skapaen slutprodukt. Studier kommer att göras angående, vilken effekt relationer har, samtvilka styrmedel som används för att effektivisera processer, vilket leder tillkostnadsreducering.Syfte: Syftet med studien är att undersöka om och hur en relation kan påverka för attskapa effektivisering för att uppnå kostnadsreducering, sett utifrån kundens perspektiv.Avgränsning: Vi har lagt störst fokus på att undersöka relationer mellan leverantöroch kund där det finns ett avgörande samarbete.

Construction companies in Sweden have for recent years seen an increase in the numbers ofwarranty complaints associated with the market of resident buildings and the cost for this hasbeen measured to over 1.2 billion SEK per year. Working with poor quality cost as a way ofcreating insight about defects within the company?s processes is a method developed and usedby the manufacturing industry for decades, but have not yet reached the construction industry.This study has been performed in collaboration with a Swedish construction company, wherethe author has been stationed at the aftersales division for residential buildings. Owing tocircumstances, this published report has been made anonymous regarding the company whowill further on be namedthe Company. The Company is aware that warranty claims producegreat costs and has requested a way of putting cost and cause to specific claims in order ofreceiving a more specific cost view and to make the reuse of knowledge more efficient.

The following article consists of two parts; one part is about house construction and the other is a specialization about radon. The house construction part describes how to project a house from start. It contains the conformation of the house, the installations needed, calculations considering the strength of the construction, energy calculation and what materials were chosen. Calculations considering the costs of building and operate the house has been carried out. The result showed that the house would cost approximately two million Swedish kroner to build and thirteen thousand kronor a year to operate.

This report describes the scientific work of designing and manufacturing an intelligent controller module prototype for automobile trailer connections. The functions of the module are both to drive the lamps and detect failures. The module also contains functions to handle other functions of the trailer. To learn about controller modules the group does extensive feasibility study.The group receives three already existing modules, the functions of the three modules are studied and tested in the lab, this is done too get a overview of the construction. The method used I called reversed engineering, a way of constructing by analyzing constructions already done.When the modules are analyzed, the functions of the prototype are tested and designed without copying the analyzed modules.

Volvo Human Monitoring (VHM) är ett pågående projekt på Volvo Personvagnar där dem bland annat mäter in- och utandning genom en mätutrustning, kallad respiratorisk induktans pletysmograf (RIP), som mäter förändringar av tvärsnittsarean av bröstkorg och buk. När föraren är i rörelse till exempel när hon svänger ändras tvärsnittsarean och en ?störning? i RIP-signalen kan uppkomma.Dessa störningar medför att vid analys av RIP-signalen måste stora manuella justeringar utföras, vilket är mycket tidskrävande, och utrustningens validitet för mätning av in- och utandning ifrågasätts.Syftet med denna studie var att effektivisera analysen av en RIP-signal som registrerats vid bilkörning. Målsättningen var att skapa ett nytt databearbetningsverktyg i Matlab som på ett automatiskt sätt kan detektera in- och utandning från en RIP-signal med högre validitet än det existerande databearbetningsverktyget.I studien utfördes tester på nio förare under bilkörning på landsväg, grusväg, motorväg och i stadstrafik. In- och utandning mättes med en RIP, en pneumotakograf med en tätt sluten ansiktsmask och ett termoelement som var placerad mellan näsa och mun som referensutrustning.Resultatet blev ett databearbetningsverktyg som automatiskt detekterar in- och utandning med högre validitet än det tidigare internutvecklade databearbetningsverktyg.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Arbetsplatsernas ständiga utveckling och förändring har lett fram till ökade psykosociala krav från de anställda som företaget måste bemöta. Ska man bedriva ett hälsofrämjande arbete bör hänsyn tas till hur kulturen ser ut på arbetsplatsen. Samlade värderingar och verklighetsuppfattningar kring hälsa skapas när individer samverkar med varandra och omvärlden, detta kallar vi ?hälsokultur?. Syftet med studien är att beskriva hur hälsokulturen ser ut på ett företag och vilka möjligheter och resurser som finns på företaget för att utveckla denna.

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.

This Degree project summarizes how it is to work in the CAD program Revit Architecture. This was done because AQ Arkitekter in Eskilstuna is interested in how Revit works. Especially compared to AutoCad which is the software they are using today. Will their work become more efficient with the new software?The starting point was to find out how it is to work with Revit when you only used AutoCAD Architecture before.

One of the most crucial entries in the financial statements is revenue. Despite the importanceof revenue a lot of mistakes are made concerning this entry because of the extensive room forjudgements. Especially in the construction companies where a lot of differences exist due tothe fact that different standards are used for similar business transactions.The research concerning IFRIC 15 and the new upcoming standard for revenue recognition isnot very extensive. Studies including both IFRIC 15 and the new standard are even morelimited. Therefore this study aims to compare the effects of IFRIC 15 and the new upcomingstandard for revenue recognition, Revenue from Contracts with Customers, in three Swedishconstruction companies.

Stenebergs sockerbruk is a large log-timber construction, purpose built as a sugar refinery in 1739 and is one of Sweden's oldest industrial buildings constructed entirely out of wood. Despite receiving the status of a listed building (in Swedish: Byggnadsminne) in 1977, there exists today a surprisingly low amount of documentation of the building itself. In order to enhance the existing and lacking building documentation, this case study aims to shed light on the building's log-timber built frame, focusing on how it was constructed, how the long lengths of its walls were handled and what type of joinery and tools were used. A thorough investigation of the building is conducted on site, followed by gathering of information which is then presented through text and illustrations. The findings indicate the orientation of timbers, location of joints and scarfs as well as tool marks which together contribute to the forming of a basis of understanding of the building's construction..
