Dammsugare att motivera till dammsugning

How can a vacuum cleaner motivate you to use it? From a sustainability perspective,the author asked the question of how such a solution would looklike? These where issues that the project tackled and devised solutions for. Theproject wanted to explore the physical modeling and a large part of the finalresult consisted of a full scale model. The project found that the problem ofvacuuming largely consisted of the problem of storage the product. The projectfound that the motivation for the job, therefore, could be resolved by a betterdesigned vacuum cleaner with a built-in hose, folding handles, which couldbe stored integrated within the vacuum cleaner.

Komet

Jag har i mitt examensarbete skapat ett cykelmärke. Syftet har varit att fördjupa mig i grafisk design och skapa en komplett grafisk profil till ett företag och samtidigt att lära mig mer om hur man skapar en varumärkesidentitet. Det konkreta målet var att ta fram tillräckligt mycket material för att cykelmärket, komet, ska kunna lanseras på riktigt. Alltså ett identitetsprogram med grafisk profil, en provcykel, kommunikationsmaterial, en hemsida, en katalog, ett event etc..

Utveckling av virtuella världen "Krimlab" - Spelbaserat lärande för tonåringar

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

The purpose of this thesis is to make a survey of attitudes toward ERP systems among business organisations and ERP suppliers.

Mjölkkyl till espressomaskin : Impressive cooler

The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.

Lokala styrelser inom grund- och gymnasieskola: Brukarstyrelser och deltagardemokratiska möjligheter och utmaningar: en teoriprövande studie

The question of direct citizen participation in politics and administration is a contestable one. Its proponents claim that it has positive consequences even for the more "traditional", representative democracy, since participation leads to an increased political knowledge and increased political interest, and thus creates a revitalised democracy. Critical voices have however been raised to the validity of this claim. Critics have also pointed out direct participation as problematic, because it leads to problems of political inequality: a difference of political influence between ? on the one hand, the citizens participating directly and those that restrict their political participation to voting, and ? on the one the other hand ? between the institutions, for example schools, that employ, and don?t employ this method of direct citizen influence.In this essay, these two points of criticisms are tested in the context of user-boards in elementary and secondary schools.

Testing and optimization of Unicorn Fluid-Structure Interaction solver for simulating an industrial problem

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

Snedställningskrafters påverkan på prefabricerade pelar-balk stommar

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

Vision Enhancement System : Vilken betydelse har displayplaceringen?

At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.

GALS,Design och simulering för FPGA med VHDL

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.

Erfarenheter av brukarmedverkan : 10 landskapsarkitekters erfarenheter av att arbeta med brukarmedverkan vid förnyelse av utemiljö.

User participation in the planning process of renewing the yards of existing residential areas was introduced in Sweden in the 1970s. It arose as a solution to many of the problems which became common in the residential areas built within the Swedish million program. The aim with the million program was to build one million homes within ten years. The same year as the million program was completed, in 1975, government subsidies to improve the residential yards were introduced. One of the conditions to get the subsidies was that the residents had to be involved in the planning process.

Rum för musik på biblioteket: En fallstudie av Bibliotek 10 i Helsingfors

The aim of this master's thesis is to study how the design of the music library space affects how it is used and its role as an arena for culture. This is done in form of a case study of Library 10 in Helsinki, a public library branch that specializes in music and information technology. The backdrop to the study is the changing context for cultural activity in the information society and the role of public libraries as public space and meeting place. By analyzing the distribution of space in the library, the distribution of functions and artefacts and the spatial use of the room, I interpret the ways in which this distributional logic produces a unique place for music and culture. I discuss the music library design in a space and place perspective, utilizing theoretical tools from cultural geography and the space theories of Henri Lefebvre.

Mikrosensorer i nätverk

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.
