Från papper till pixel : Kvarnholmen studerad utifrån historiska kartor med stöd av GIS
Sweden has a long tradition as a mapmaking nation. Tens of thousands of historical maps,dating from the sixteenth century and onwards are still preserved in archives today, providinga rich resource for studies of city growth and changes in the landscape through time. For morethan ten years an effort has been made by public authorities to transfer this material frompaper onto digital media. Due to modern technology, as for example GeographicalInformation Systems (GIS), researchers have been given improved possibilities to study andanalyze this material. This study uses a qualitative approach, based on both literature studiesas well as map studies.
Modellen och materialet
Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today. At the present time, dueto the relocation of the E4 highway east of Uppsala, Tycho Hedéns road creates a barrierbetween the north eastern area of Uppsala and the remaining parts of the city centre. Theroad is designed to endure heavy traffic and high speed limits, generating a surrounding urbanarea were inhabitants are complied to follow the standards set for a high traffic-accessibleenvironment. Furthermore, the heavy traffic has led to the turning of both urban roadsidesaway from the actual road. The aim of this project and proposal is to show the possibilities ofhow the innate features of Tycho Hedéns road can be used more advantageously to mend thecity area of Uppsala.
Tryckhållfasthet för resurssnål betong : Utvärdering i tävling av högsta tryckhållfasthet för resurssnål betong
Betong är vårt vanligaste byggmaterial men cement står globalt sett för 5 % av CO2-emissionerna. Med detta som bakgrund så har CBI Betonginstitutet anordnat en tävling, där målet är att nå den högsta tryckhållfasthet i en resurssnål betong, med enbart 200 kg cement per m3. Syftet med denna rapport är att utvärdera tävlingen, vilket har utförts genom en omfattande litteraturstudie. En första analys av de olika betongrecepten medförde att olika grupperingar kunde urskiljas. Ur dessa fanns det tre stycken vars resultat var väldigt bra. ? Concrete Innovation Centre, som med ett lågt vct, stora mängder granulerad masugnsslagg (81 %) och lite silikastoft (5 %), uppnådde en tryckhållfasthet på 80 MPa vid 28 dygn och 95 MPa vid 56 dygn. ? CBI Stockholm, som genom användandet av ulltrafint filler och silikastoft (4,8 %), uppnådde en tryckhållfasthet på 84 MPa vid 28 dygn och 98 MPa vid 56 dygn. ? Thomas Concrete Group som genom att ersätta cementet med en medelmåttig mängd granulerad masugnsslagg (54 %), liten mängd flygaska (9 %), kalkfiller och silikastoft (5 %), uppnådde en tryckhållfasthet på 94 MPa vid 28 dygn och 98 MPa vid 56 dygn. Det finns således tre recept som vidare studier kan vara rättfärdigade på, de tre ovan nämnda. Det bör tilläggas att en imponerande tryckhållfasthet på nästan 100 MPa, kan uppnås i en betong med enbart 200 kg cement per m3. .

Each participator of the project trained a dog towards a specific goal. This goal was individually formulated by each participator from his or her specific interest.
Acehkonflikten - en analys med identiteten i fokus
A violent conflict emerged in the Indonesian province of Aceh in 1976, with the rebels of the Free Aceh Movement, GAM, on one side, and the Indonesian government on the other. GAM demanded Aceh to become independent, but the Indonesian government did not accept their nationalistic claims. The conflict therefore lasted for almost thirty years, and many civilians were killed during this period. This essay deals with this particular conflict; its causes and its solution. In the centre of the analysis we find theidentity of the Acehnese people, and the way in which this identity has beenconstructed and re-constructed throughout the history.
Uppgradering av robotsystem på Termisk sprutning, Volvo Aero
This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.
Ungdomsmottagningen : En kvalitativ studie om hur barnmorskor förhåller sig till det tänkbara etiska dilemmat mellan ungdomars rätt till integritet och föräldrars rätt till insyn
Youth centres- A qualitative study of how midwives relate to the potential ethical dilemma between youths right to integrity and parents right to informationThe aim of this study was to investigate how midwives at youth centres relate to the potential ethical dilemma between parents? right to information that young people between 15-17 years share at the centre, vs. youths right to integrity. The study was based on qualitative interviews with six midwives in various youth centres in Stockholm County. We analysed our empirical material according to Blennbergers consequential ethical model and Bronfenbrenners ecological system model.
?Det här var dagen då anonyma tonåringar via sociala medier startade ett upplopp i Göteborg? En studie över gestaltningen i fyra svenska tidningar av gatuoroligheterna vid ?Instagram-händelserna? i Göteborg år 2012.
On subsequent days, the 18th and 19th of December 2012, large groups of young people gathered to protest in the centre of Gothenburg. The gatherings mainly occurred outside two high schools: Plusgymnasiet and Framtidsgymnasiet. The reason behind the gathering has often been explained by the young people?s reaction to an Instagram account, on which offensive pictures and comments of and about young boys and girls had been published. As a reaction to the protest, police force including helicopters and mounted police, was sent to the streets.
Jobbkontroll, stress och prestationsbaserad lön inom callcenterbranschen
The application of performance-based pay system among enterprises is becoming more frequent. Performance-based pay systems is used by organizations in hope of increasing productivity and have become more flexible. Employees may perceive the performance-based salary as a motivator or a threat depending on lifesituation and personality. At a perceived threat, the employee may become stressed. Work-related stress has become a serious social problem that can have consequences for both companies and individuals.
Mätning av stamdiameter med markstående scanner :
Booth for operational planning of harvesting and for long term planning, data is today collected manually. Intensive objective field inventories are usually too expensive. To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. The objective of this study was to validate how a terrestrial laser scanner could be used to measure stem diameter, and to test how the errors depend on distance from the scanner and tree species.
Two plots (one pine and one spruce) were used for this study.

AbstractPropose/Aim: The aim of this paper is to examine why the view of the conceptions, within the field of professional information and communication, seem to differ within the labour market of Sweden. This paper will investigate the two main professional roles that are at the centre of the field?s confusion and disorder. These are the Information Specialist and the Communication Specialist. The main question here is to answer whether there is a significant difference between the two or not and also gain knowledge about why the two titles are not used consequently within the labour market.Material/Method: The method used for this study is of a qualitative character.
Utökning av mätområdet för turbinverkningsgraden på avgasturbo
The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.
Riktlinjer för studier av icke-existerande komplexa sociotekniska system : Erfarenheter från en studie av införandet av ombordbaserad helikopter på korvett av Visbyklass
This report consists of a discussion about suitable methods for studying complex sociotechnical systems that are still being developed. There are large economical advantages with studying new systems before they are completely developed since problems can be discovered early and thereby avoided. It is, however, difficult to study developing systems, there are methodological limitations. These limitations are discussed and recommendations for studying non-existing complex sociotechnical systems are presented.The report is based on experiences from a study of the introduction of a shipboard helicopter on the corvettes that the Swedish Armed Forces are developing. A shipboard helicopter implies high requirements on the hosting ship.
