Arbetet handlar om att skapa en mönsterkollektion för Eco-Boråstapeter. Kollektionen består av fem mönster som behandlar struktur, volym, rörelse och rytm. Tapeterna trycks med djuptrycksmetod på slätt bestruket non woven-papper. Målgruppen är unga designintresserade människor. En designprocess utifrån en inspirationsfas redovisas som består av experimentella filmer (Grey Gardens, Gummo och The Brown Bunny) och av fotografier tagna under promenader i Växjö.
CMS-baserat studentintranät : Undersökning och utveckling av studentintranät
Involving prospective users in a development process is important. This makes it easier to make a more usable product. This thesis is about developing an intranet targeting a school and focus is aimed towards intranet usability.The reader is given knowledge into how to design and implement an intranet using persona. Design and develop by using persona is difficult when there is a group with large variety of knowledge, age and technology interest, so as in this case. Persona although always helps during the development phase because of the strong links to the personas that are created, which gives developers a constant reminder of the end users of the system.The thesis describes how information is collected and processed.
Från grej till kvadrat : Om begreppsförståelse inom geometri utifrån läromedel
One of the purposes of this work was to find out what it means to have a conceptual understanding of geometry. It describes how the geometry evolved from history and the geometry that is taught in grade one to nine and collage. The area examined was based on fundamental geometric objects for example two- and three- dimensional objects and its characteristics and especially focusing on the areas of perimeter, area and volume. The literature- review showed that the conceptual understanding was primary to developing a good knowledge of geometry. The second purpose of his study examined whether pupils achieved the goals in geometry by working with a Mathematics Book.
Vad får jag egentligen skriva om min arbetsgivare på facebook och andra sociala medier? : Yttrandefrihet möter Lojalitetsplikt
In today's society the borders between work and leisure blurs out more and more, and just as we might bring our work home, we might as well take our leisure to work with the help of so called smartphones with constant connection to social networks such as facebook and twitter. But what happens when the small talk around the coffee machine in the workplace gets out in public spaces? Instead of complaining to my closest colleague when my boss is acting like a fool or when my workload sky rocketed, I might now instead update my status on facebook with my complaint. But what am I actually allowed to write about my employer? And has the employer any possibility to act legally in respond to what I write?For the younger generation, who more or less is grown up with these social networks, I think this demarcation can be difficult to draw and understand.In this essay I deal with the issue of whether a principle of law, such as the duty of loyalty might collide with my constitutional right to use freedom of speech against my employer..
Utvärdering av flygbildstolkning för uppskattning av beståndsvariabler och åtgärdsförslag i ungskogar : en studie på Korsnäs Skog och Bergvik Skog AB i västra Dalarna
In Korsnäs district Dala Väst there were problems with information concerning their younger forests, mainly those in pre-thinning stage. They were divided into large, heterogeneous stands with often poor stand data quality. In 2006 an aerial photo interpretation of the young forests was conducted to fix these problems. Necessary information to get from the interpretation were silvicultural management suggestions, new stand delineation and new stand data. This thesis is supposed to evaluate the quality and usability of the interpreted data.
To evaluate the interpretation an objective control inventory was conducted in 60 stands, either through callipering or counting stems.
Fjärrlåneverksamheten på Borås och Kalmar högskolebibliotek
The object of this essay has been to investigate the interlibrary loan service at the universitylibraries of Borås and Kalmar. For this purpose a quantitative and a qualitative methodhave been used.The main body of information consists of statistic data concerning the incoming interlendingorders for a three-month-period. In order to examine the circumstances under which theinterlending activity exists several interviews were made.The study showed that there are several important factors which together make up the complexitythat governs the interlending activity. What type of demand there is depends on theeducational level, whether the different study programmes have a broad or limited subjectorientation or not, and if the demand is of a constant or an inconstant nature. Well-establishedroutines at the information-desk and co-operation with the departments of the different studyprogrammes are important factors in keeping the knowledge of what books and serials areneeded up to date..
Noble Operations: En studie av Stadshuskällarens processflöden
The aim of this thesis is to study Stadshuskällaren?s operational processe flow and identify their operational characteristics. The uniqueness of Stadshuskällaren is that they are breaking the law of trade-offs regarding volume/variety, much like Toyota managed to do ? which spawned the entire field of research of the ?Lean Philosophy?. In the thesis the characteristics we identify through analysis, which enables Stadshuskällaren to break the trade-off, are compared with the principles of Lean service theory, which ultimately stem from Toyota.

Peltierelement - spillvärme till el : Peltier element - waste heat into electricity
The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.
Volyminspirerat arbete i förskoleklassen - en prioriteringsfråga? : En studie om förskolelärares uppfattningar om volyminspirerat arbete
Syftet med denna studie är att få ökad insikt om hur förskolelärare uppfattar sitt eget arbete med att främja barns begreppsutveckling inom området volym. Syftet med studien är även att få ökad kunskap om vilka aspekter som påverkar den dagliga verksamheten inom området volym i förskoleklassen. Denna undersökning är baserad på intervjuer med sex förskolelärare, materialet har bearbetats och kategoriserats under fem stycken huvudrubriker som belyser olika aspekter av hur förskolelärarna uppfattar att de arbetar med området volym i förskoleklassen. Vi har valt att belysa denna undersökning ur ett sociokulturellt perspektiv. I vår analys har vi kommit fram till att det finns många olika aspekter som påverkar utformandet av verksamheten i förskoleklassen.
Skredriskutsatta områden vid ett förändrat klimat - Konsekvenser för vattendistributionen i Göteborg
This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.
Optimering av B-stolpe
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Mätning av partikelmassa i avgaser från en dieselmotor
This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.
DEN TILLHÖRIGHETSSKAPANDE MÖTESPLATSEN - Folkbiblioteket som mötesplats i svensk biblioteksdebatt
This Master's thesis concerns the public library as a public meeting place. Our aim has been to find out why and how the library as a social meeting place has been discussed within the Swedish library community and if there has been a constant core in the discussions from the mid 70's and up to the present day. In order to do this we apply a place and space-perspective. The result of the study is that the core of the said discussions concerning the library as a meeting place is to create belongingness. This is the reason why the library community has an interest in the public library's function as a meeting place with the idea that people, by using the public library in that aspect, may experience a feeling of belonging to the society.
