VBG Produkter AB is a process-orientated company that develops, manufactures and markets trailer couplings with belonging coupling equipment, protection equipment against skidding and stands for wagon-bridge for heavy vehicles. The company feels that their set-up time in production for couplings is not at an acceptable level. Due to high demands of customer oriented production the intermediate stock level of included products within the assembly of couplings has gradually increased which has resulted in high inventory holding costs. VBG Produkter applies Kanban in their production, therefore it is important to produce exactly the necessary amount and avoid overproduction. The objective of this project is to suggest appropriate solutions so that VBG Produkter is able to reduce their set-up time in assembly of couplings, by identifying internal and external set-up time for the chosen process bushing cell.

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

The decision of the European Commission to block the merger between Volvo and Scania in the late 90?s became the starting point to the debate of the possible discriminating effects of the European merger regulation. Especially since the Commission a few years earlier had approved of the merger between Mercedes-Benz and Kässbohrer on the German bus market, where the conditions for competition had been similar to those at hand in the Swedish case. The issue that was and still is in focus is whether the European merger regulation is more difficult to pass for large companies situated on a smaller domestic market than is the case for their competitors of corresponding size but situated on a larger domestic market.This thesis aims at examining what the judgement of the geographical relevant market means for the application of the Merger act. This is being done from two perspectives.

Detta examensarbete har genomförts på Volvo Aero i Trollhättan och består av tre delar: en kartläggning av processventilationens uppbyggnad på ett antal utvalda maskiner och beräkning av dess energiåtgång, en jämförelse ur energieffektivitetssynpunkt mellan ett nyutvecklat maskinkoncept som kallas MultiTask-Cell och traditionell tillverkning, sist har en tomgångsanalys gjorts i verkstaden för att identifiera vad som använder elenergi då ingen produktion sker.För att kunna genomföra uppgifterna har mätningar av elanvändningen gjorts på både maskinnivå och transformatorer, detta för att kunna beräkna energianvändning på utvalda maskiner och även få en helhetssyn över verkstadens energianvändning. Det har även gjorts datainsamling och intervjuer för att få grepp över processventilationens funktion och uppbyggnad.Det finns två varianter på processluften, ett där konstant relativt högt luftflöde används och ett när man genom varvtalsreglering av fläkten använder ett lägre grundflöde som forceras en viss tid vid spindelstopp. Ur energisynpunkt är metoden med grundflöde och forcering att föredra då det leder till både mindre energiförluster genom processluften och en stor minskning av fläktens elbehov. Det har även räknats ut en teoretisk energibesparing vid införande av värmeåtervinning för två maskingrupperingar.Jämförelsen mellan MultiTask-cellen och traditionella maskiner har gjorts genom att mäta den energi det krävs för att tillverka en detalj för respektive tillverkningssätt. MultiTask-cellen visade sig använda cirka 25 % mindre energi än de traditionella maskinerna för tillverkning av samma typ av detalj.Tomgångsanalysen visar på ett högt effektuttag även då det ej sker någon produktion på Volvo Aero.

Volvo Powertrain tillverkar motorer och drivlinor till AB Volvos samtliga dotterbolag förutom Volvo Aero. Vid anläggningen i Skövde tillverkas motorer och delar till motorer och växellådor och vid anläggningen finns alla tre nödvändiga produktionsområden; gjuteri, bearbetning och montering. När rådande lågkonjunktur slog till stod bearbetningen med väldigt höga lagernivåer vilka företaget snabbt tvingades sänka då det blev huvudfokus från koncernledningen att minska det bundna kapitalet. Utan egentlig analys sattes nya gränsnivåer för lagren inom samtliga avdelningar på bearbetning och målet med examensarbetet har varit att ta fram en metod för att dimensionera säkerhetslagret på optimal nivå med bibehållen hög leveranssäkerhet. Därigenom skulle företagets lagernivåer kunna styrkas med hjälp av en teoretisk grund.Som utgångspunkt har en lagernivådimensionering med servicenivåkonceptet SERV2 och där alla artiklar tillåts ha differentierade servicenivåer använts.

Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.

How do we match our education with the needs of the construction line of business and the requirementsof the Swedish National Agency for education? Is there something that we have to change?In this study I have asked our former students about their opinion of our education and I have also asked them to give me their view on what a good teacher is like. I have been able to benefit a lot from their answers in my efforts to be that good teacher. This survey took place at Facebook.The answers showed that we carry on a piece of solid workmanship. But you can always improve, try harder.

This Master Thesis describes how a concept for a new fly fishing reel has been developed. Thethesis has been an interwork with Loop Tackle Design, which is a leading company in the flyfishing industry with their high-quality products. Loop designs and develops all types of flyfishing equipment like fly fishing reels, rods, lines and clothes.The purpose of this thesis is to generate a concept for a new type of fly fishing reel. The new flyfishing reel shall be innovative and reduce the number of components in fly fishing equipment.The solution for this is to create a fly fishing reel that is collapsible and can be used for all typesof fly fishing.The thesis started with a history of fly fishing and the equipments that have been used for flyfishing in the past and what is used today, in order to get an idea how fly fishing haveprogressed. A frame of reference was then compiled to get an idea of the forces and surroundingsa fly fishing reel will be exposed to.

During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

This report is about how to decide which method is the most suitable as floor covering at projectKlammerdamm in the centre of Halmstad. The covering has to be fire resistant and soundproof inorder to protect the wood structure and stop noise from traveling between apartments. There aretwo possibilities either traditional gypsum board or gypsum-based self leveling underlayment.The roads around the construction site are narrow. A regular twenty-five meter long truck has nopossibility to reach the site. The construction site is small and the storage area is limited.

The projecting time in the construction industry needs to become more efficient toshorten the amount of time it takes to project a build. One of the North's leadingconstruction company NCC constuction Sweden AB has developed a form ofcollaboration called ?NCC project studio? that they use in some projects today.My thesis consists in bringing forth the most important aspects of the collaborationform called NCC project studio. The point of this is to use my thesis to help thecompany develop a quality document that can assist them when starting collaborationbased on NCC project studio in the future.The conclusion of my thesis was that much of the focus needs to be on explaining tothe participants what NCC is aiming to gain from working with the NCC projectstudio and also which important parts that needs to be worked on..
