Utveckling av en ny typ av båtstål åt Rupert Marine AB
Rupert Marine tillverkar och säljer RIB-båtar, som är små snabba båtar med riktigt, stelt, skrov och uppblåsbara tuber runt skrovkanten. Bakgrunden till denna masteruppsats är att det ofta finns stora brister i förarmiljön och förarplatsernas utformning på båtar. Företaget upplever att man har en lucka i sitt utbud av stolar. Det saknas en komfortabel och multifunktionell stol för fritidsanvändare. Det finns företag som tillverkar stolar separat för mindre snabba båtar.
Det svenska områdesskyddet : Ett samspel mellan diskurs och institutioner
Sweden has had laws protecting nature for about a hundred years. In this paper the views of nature and the values that serve as a rationale for protective measures are analyzed as results of a social process characterized by the dialectic relationship between institutions and discourse. Critical discourse analysis (CDA) is used to study this relationship and the discursive practices used by institutions, which reproduce or reshape views of nature that define the relationship between society and nature. Institutional design contributes to shaping discourse in the field of nature protection, while being originally shaped by discourse. In Sweden, the national park is an institution that reproduces a view of nature as the wild and untamed opposite of society, and the natural reserves reproduce a view of nature as holder of a multi-faceted set of values intertwined with society.
Kloridhalter i gran utmed en depositionsgradient för havssalter :
The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.
Konstruktion rörklammer
This report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers? patents but also to generate ideas.
Samrådsunderlag för Lysekilsprojektet : Forskning och utveckling av vågkraft
The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
Underlag för framtagning av målningslina : Hantering och layout
Seabased Industry AB develops system for extracting electrical energy from ocean waves with a Wave Energy Converter (WEC). The components is bought from subcontractors and then assembled into wave energy converters, buoys and marine substations by Seabased. In the future Seabased will produce more of the components themselves to reduce costs and to have better control over tolerances. The production line will also include the painting of the WECs and substations, which is performed in a painting line.The purpose of this thesis work is to study what is required to build a painting line, regarding the types of stations, transporting types and the space needed. This will result in layouts for the painting line.To receive the necessary information about production theory and corrosion and surface treatment, literature concerning this area has been studied.
GENERATION Y : Attrahera, behålla och leda i byggbranschen
Within the next ten years, the largest generationchange ever will take place in the Swedish constructionsector. The purpose of my study is to examine themajor differences between "Generation Y" and previousgenerations. This is done in order to find out how theNCC will attract the employees of the next generation,manage them at work and finally be able to keep theemployees that has been trained internally over alonger period of time.Previous research has been based on theories ofGeneration Y in general. It investigates the distinctivecharacteristics and qualities of the generation, andalso how their upbringing may have shaped them intowhat they are. Three respondent groups wereinterviewed: Engineer students of "Generation Y",officials at NCC belonging to "Generation Y" andmanagers at NCC.The results of the study show that "Generation Y"differs from previousgenerations, and how they differ.
Betongarbeten under vintertid : Fokusering på platsgjuten betong
This report is on concrete work during the winter and is implemented on Peab?s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting.
UV-tork - analys av drift :
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.
High Mobility Engineer Excavator eller Ingenjörbandvagn 120 : Om olika fältarbetsfordon ger olika förmåga till fältarbeten för rörlighet
Ingenjörtrupperna har nyligen tillförts två nya typer av fältarbetsfordon. Då ett avingenjörförbandens största uppgifter är att understödja med ökad rörlighet för förband, anserförfattaren det vara relevant att studera hur dessa fordon kan understödja med detta.Enligt den struktur som ingenjörbataljonen skall vara organiserad 2014 skall dessa nya fordonutgöra huvudstommen i maskinplutonerna på de bandgående och hjulgåendeingenjörkompanierna, vilket kan föranleda vissa begränsningar och/eller fördelar då demaskinplutonerna tidigare har utgjorts av mer specialiserade arbetsmaskiner såsom hjullastare,grävmaskin och grävlastare. Detta kan innebära att de bandgående och hjulgåendeingenjörkompanierna blir till viss del mer lämpade att genomföra olika sorters arbetsuppgifterför att öka rörligheten för förband. Slutsatser ifrån undersökningen påvisar bland annat attIngbv 120 är mer lämpad att genomföra fältarbeten för rörlighet i bebyggelse än vad HMEEär, och att båda fordonen kan genomföra i stort sett lika många olika sorters fältarbeten förrörlighet, med undantag för minbrytning vilket bara Ingbv 120 kan genomföra..
Valbara kurser : En enkätstudie om valbara kurser för sjöingenjörsstudenter vid Sjöfartshögskolan i Kalmar
På ingenjörsutbildningar får studenter fördjupa sina kunskaper i programmets senare del i form av specialinriktningar eller valbara kurser. Detta är något som inte är tillgängligt för studenter som läser till sjöingenjör vid Sjöfartshögskolan i Kalmar men något som infördes på sjöingenjörsutbildningen vid Chalmers Tekniska Högskola 2009. Studiens syfte är att undersöka intresset för valbara kurser på 7,5 högskolepoäng (hp) vardera för sjöingenjörsstudenter vid Sjöfartshögskolan i Kalmar. En enkätstudie svarade på frågorna om vilka ämnesområden som var av intresse, hur många kurser eleven ville läsa, när under utbildningen önskas kursen läsas, om intresset för valbara kurser saknas och i så fall varför. Resultatet av undersökningen visade att de ämnesområden som är av störst intresse för studenterna på grundnivå är offshore/oljerigg och landkurser.
Styrd borrning eller konventionell schaktning : en jämförelse av två rörläggningsmetoder
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.

Standardisering av snöröjningsplan : Instruktioner, råd och tips för snöröjning av tak med stora spännvidder
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.
Automatiserad laddning och plundring mellan magasin
This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.
