Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

Gamers and Game Design: Incorporating Users in the Design Process

This paper deals with the difficulties of applying user-centered design practices as an independent developer, based on the visualization of a game concept in the form of a prototype. The aim is to evaluate the usability of user-centered design practices, specifically in the field of games development. Throughout this paper, I will give an account of the methods used for testing, as well as a review of previous research done in this field of study. Finally, I will end with a discussion regarding the pros and cons of user-centered design, as well as some thoughts about its importance in similar projects..

Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

Skarven : ? Produktutveckling av en oljedimavskiljare

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

GPS- & GIS-användning i drivningsprocessen hos Stora Enso SKog AB :

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

PixelCity Sharp-X : Jämförelser ur utvecklarperspektiv mellan C++ med OpenGL och C# med Direct3D

This essay serves to illustrate the main practical differences between the popular medium-level programming language C++ (C Plus Plus), and the newer high-level language C# (C Sharp). It will focus on the aspects that are readily apparent to the application programmer, such as differing syntax, constraints and capabilities.It will also feature a similar comparison between the open source OpenGL graphics library, and the proprietary Direct3D graphics library owned by Microsoft Corporation.It will not go into the differences in ?under the hood? mechanics that the application programmer seldom have to consider after having chosen his programming language or graphics API, such as C# being compiled into an intermediate language and is run on a virtual machine where C++ is compiled directly to machine code, or the differing principles of rendering in OpenGL and Direct3D.This is by no means comprehensive, many things have been left out or overlooked..

Attityder till design : samt studie- och yrkesvägledare

The background to this study is the government’s investment in design and the increase of design education around the country. As a future design teacher (industrialdesign) at high school/college, it is of great interest for me to look closer at student’s attitude towards design and design educations at high school.Questions that have been investigated are student´s attitude towards design; design as a concept but also as a phenomenon. How does the student counselor inform the students of the differentchoices before choosing high school?Does the students view on design correspond to what the student counselor say?What opinion does the student counselor have to the concept design as well as design in highschool? Is design just a craze or here to stay?To get answers I have made interviews with student counselors at two different schools, I have also been in contact with a student counselor on the internet. Their thoughts will clarify thesituation that the students might be in.

Minimalist design for children?s games

The aim of this report is to see whether the graphic design of a game influences children?s will to play games. I am especially looking at minimalist graphic design and how well it works for a game aimed at children age 7-9. Does the style of the game design have any impact at all concerning the children?s wish to play the game or is the game mechanic all that matters.

Netadmin Systems är ett Linköpingsbaserat IT-företag där huvudprodukten NETadmin är ett Operation support system/Business support system (OSS/BSS) som i huvudsak används i öppna nät för bl.a. kund- och lagerhantering, provisionering, övervakning och ärendehantering. Ett växande behov finns att göra det möjligt att använda övervakningssystemet via mobila enheter för att kunna felsöka och hantera driftstörningar effektivt.Syftet med rapporten är att undersöka hur övervakningssystemet kan göras tillgängligt på Android samt att ta fram en prototypapplikation för hantering av grundläggande övervakning. Genom fallstudien som har genomförts har slutsatsen dragits att Netadmin API är lämpligt för kommunikation via mobila enheter men att API behöver vidareutvecklas med ytterligarefunktioner. De viktigaste av dessa har implementerats och arbetet har även mynnat ut i en applikationsprototyp för Android.Genom utvecklingen av denna applikation ges Netadmins kunder möjlighet att hantera övervakningssystemet via mobila enheter..

Hundratusen rullar fram i Sverige : Det enda som stoppar rörelsehindrade är omgivningen

Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.

Reglering av matarsystem vid höghastighetskapning

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
