Nytt spritsrör på TwinRoll typ TRPE : Undersökning av kostnad på spritsrör

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

För gammal för att köra bil? : En kostnadsnyttoanalys om Sverige bör införa körkortskontroller för bilförare över 75 år

Varje år ökar antalet äldre personer och i samband med den ökningen blir även antalet äldre personer med körkort allt fler. Med åldern är det vanligt att reaktionsförmåga, syn och hörsel försämras vilka alla är viktiga egenskaper för trafiksäkerheten. Läkare i Sverige är skyldiga att rapportera till Transportstyrelsen om en individ inte anses vara lämplig att köra bil. Att läkare över huvud taget tar upp körkortsfrågan med sina patienter sker endast i 60 procent av fallen och därmed fortsätter många olämpliga körkortsinnehavare att köra bil. Majoriteten av länder inom Europeiska Unionen (EU) har någon form av övre åldersbegränsning i körkorten där körkortsinnehavarna måste genomgå en kontroll för att få körkortet förnyat.

Livscykelkostnadsanalys för beläggningar i containerterminaler : en förstudie för bättre beslutsunderlag vid investeringar i terminalytor

Pontarius AB har tillsammans med Göteborgs Hamn AB identifierat behovet av en utvecklad holistisk modell för bedömning av investeringar i terminalytor. För detta har en första ansats gjorts med den interna livscykelkostnadsanalysmodellen Total Cost of Ownership and Operations (TCOO). Livscykelkostnadsanalys (LCCA) är ett verktyg för att handskas med ett projekts totala kostnader vid investeringsbeslut och bedömning av alternativ. Generella livscykelkostnads-modeller är svåra att ta fram, varför istället utförliga modeller vanligen skapas för specifika områden. För vägbeläggningar, och tillviss del flygplatsbeläggningar, finns utförliga sådana metoder, men för beläggningar i containerterminaler saknas det.För att fortsätta utveckling mot en bättre bedömningsmodell för terminalytor syftade studien till att identifiera kostnadsparametrar som sett ur ett livscykelperspektiv påverkar kostnaderna för containerhamnterminalytor.

Development of Liquid Cooling for PCs

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

DET HÄR ÄR OCKSÅ GRAFISK DESIGN - Ett bidrag till diskussionen om ornamentik, funktionalism och kvinnors marginalisering.

This thesis examines the relationship between the marginalization of ornamentation during functionalist modernism and the effect it had on female graphic design practice. By examining the historiography from a gender and feminist theory of history I present a different way of interpreting, not only the history of graphic design but also the concept of graphic design. This thesis does not reach a conclusive result, instead it sets the foundation for further research and illustrates the opportunities that we as graphic designers have to benefit contemporary graphic design by critically reviewing and redefining our history through a diverse historiography..

Brottsförebyggande arbete i Karlskrona Kommun

Theft without break-ins has increased significantly in the last year of swimming, sports and leisure facilities in Karlskrona, more precisely 60%. Vandalism in the shape of graffiti is another common crime. The solutions are divided into social and situational crime prevention. Social crime prevention engage in actions that are based on social causes of crime rather than the opposite situational crime prevention, which instead assumes that discourage with the help of technical solutions and has as primary objective to hinder accessibility for example theft friendly goods. The main purpose of this work is to come up with solutions to prevent these crimes, while also being cost-effective and realistic to implement. The work is important in that it creates safety awareness and promotes a healthy safety culture. Moreover, the future goal is to lower these statistics. The goal of the work is in addition to developing our knowledge of crime subject, was also to provide help and solutions for our clients.

How canan ATC in Musoma be developed into a stimulatingand educational park suitable for teaching agroforestrymethods to peasant farmers and other potential users?To answer that a field study was conducted to investigatehow our client Vi Agroforestry Programme (Vi) and thetarget groups of the client can benefit from the site.The thesis begins with a short explanation of thecontext, in which the ATC plays a part followed by amethodology chapter. Next are three chapters presentedwhich introduce the reader to the research conductedbefore starting the proposal, these include: results ofliterature studies, study of precedents, and results of fieldstudy.

En jämförelse av levnadskostnader för en tvåbarnsfamilj i Arvika- och Kongsvinger Kommun [A comparison of cost of living for a family with two children in Arvika and Kongsvinger]

Den här uppsatsen är skriven på uppdrag av GrenseTjänsten Morukulien, vilken är en organisation som hjälper personer, företag och andra organisationer som har ärenden i både Sverige och Norge.Syftet med uppsatsen är att jämföra levnadskostnaderna för en tvåbarnsfamilj i Arvika- och Kongsvinger Kommun. Detta görs genom att se vilken familj som har störst köpkraft. Med köpkraft menas hur mycket man kan konsumera för sin disponibla inkomst.Levnadskostnaderna jämförs för en genomsnittlig tvåbarnsfamilj. Undersökningen bygger på att alla kostnader läggs i boendelandet. Vidare utgås det ifrån att båda familjerna har samma konsumtionsbeteende som en genomsnittlig svensk tvåbarnsfamilj med jämförbar inkomst.

The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.

Utsikt för olja : Hur värderas oljeaktier

Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.

Hallsta Pappersbruks virkesförsörjning

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.

Miljöbyggnad, GULD värt? : En undersökning av fastighetsägares erfarenheter och tankar kring ett nytt certifieringssystem

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Konvertering från luft till vätskekylning av elektronik

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.
