I mötet mellan tradition och förändring : Om Wikipedia som encyklopedi
This study is about Wikipedia which defines itself as a free online encyclopaedia. Our chief interest lies in the debate and the controversy which has arisen around Wikipedia. After reading critical articles concerning Wikipedia we found that the debate for most parts had one identifiable theme namely the question whether Wikipedia is an encyclo-paedia or not.Encyclopaedia as a term and a phenomenon has a long tradition. Wikipedia, despite calling itself an encyclopaedia, functions differently in comparison to more traditional encyclopaedias. These traditional views involve encyclopaedic structure, its organiza-tion and its functions.
Halvledare för höga strömmar i fordon
Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.
Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning
To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.
The RECK gene and invasive cancer development : the significance of RECK in angiogenesis and inhibition of matrix metalloproteinases
The RECK gene is a relatively new discovered gene with important implications for cancer research. The research has been primarily concentrated on the human gene with the ultimate aim to identify the invasive characteristics. Up regulated RECK is linked to significantly prolonged survival rates in patients with severe forms of malignancies.
RECK is normally expressed in all cells of the body and has an important role in the balance between destructive and constructive features of the extracellular matrix. The RECK protein is a membrane-bound glycoprotein that inhibit matrix metalloproteinases which has the function of breaking down the ECM. There is a significant correlation between RECK gene expression and the formation of new vessels, presumably via the mediation of VEGF which is an important and powerful inducer of angiogenesis.
Det magiska biblioteket: Rollspelares uppfattning om bibliotek
The aim of this thesis was to examine how role players experiences libraries and if the libraries are or can be an arena for activities that involves role play. A public library exists for everyone, but could nevertheless be viewed as a female sphere where women both borrow more books and visit the libraries program activities to a larger extent, compared to men. I asked the question whether men?s reason for choosing a different venue for information and culture was related to the libraries not being able to satisfy their needs. The theory of the thesis was Dorte Skot-Hansen, Casper Rasmussen Hvenegaard and Henrik Jochumsens model that states that the libraries can have four different functions and act as a venue for meetings, knowledge, inspiration and experiences.
E-tidningens attraktionskraft på annonsörerna : En flört eller början på ett varaktigt förhållande?
The technical development is advancing at high speed and now the turn has come for the traditional paper to digitalize into the so called e-paper. The newspaper industry has started to investigate the future possibilities of publishing the traditional newspapers on e-paper. Today?s newspapers are mostly financed by advertisement incomes, which makes the advertisers important players, who must be taken into consideration at an introduction of the e-paper. Since the e-paper does not exist as a finished product in the market today, in this essay we look into what kind of functions or services that can attract advertisers to the e-paper on the basis of the experiences made with the breakthrough of the web-newspapers.

Steg 18a : En kvalitativ analys av LUS
The purpose of this paper is to examine how teachers comprehend LUS as a development program, but also how they think about one of the points in the program. The study is based on interviews with five teachers working with ages between preschool to ninth grade.The results show that the development program is splendid, it doesn?t come with a lot of paperwork and it has a humanistic approach. When it comes to point 18a which is the main examination, the teachers mainly agree with each other. They all talk about preunderstanding, reading speed and the amount of literature as the main characteristics to be placed at point 18a.
3D modelling of a Laser Welding Cell for movie presentation : making of the movie
This report describes a Bachelor thesis work in which a robotised laser welding cell has been modelled and simulated for the purpose of making a presentation movie. The report shows that the work has been concentrated on making the movie from the modelling phase through the recording of the movie and ending up with the editing of the final presentation movie. A pre-study was made prior the Bachelor thesis work. In the pre-study a literature study was conducted about measurement and calibration of a welding cell. Measurement of almost all equipment in the entire cell was also conducted in the pre-study.
?? det är mycket lättare att tala om vad som är svårare.? ? Gallring av tryckta böcker och dess konsekvenser för bokbestånd vid folkbibliotek
The aim of this study is to illustrate conceptions held by librarians and library and information scientists about weeding practices of printed books in public libraries. The study has been carried out by performing a series of qualitative interviews with librarians and by study of earlier research relating to the subject of weeding. The results have been analysed by utilizing a textual analysis method called idea and ideology analysis using so called dimensions to analyse and structure the results. The results indicate that weeding at Swedish public libraries is carried out by a mixture of objective and subjective methods, with certain statistical elements. Weeding procedures mainly appears to be legitimized according to what one refers to as knowledge of the local community, although lack of lending are cited from time to time.
Bland boktips och länksamlingar : En undersökning av de svenska folkbibliotekens webbplatser för ungdomar
The public libraries were quick to adapt to the changes that the Internet brought on, and today library websites are an important part of the public library. To meet the needs of teens today, the library website could offer a range of contents to make it an attractive place on many levels; both the academic needs as well as social and recreational needs should be addressed.The aim of this thesis is to evaluate public library websites for teenagers in Sweden, and to examine how well the websites address the developmental tasks and needs that teenagers have. The method used is website evaluation, one quantitative and one qualitative. A total of 60 public library sites for teenagers were evaluated, using 11 criteria based on Havighursts developmental tasks. The quantitative evaluation measured how many functions each website had per criteria, and showed that the majority of the sites had one or two functions for most of the criteria.
EU som demokratifrämjare? : En jämförande studie av Europeiska Unionens demokratifrämjande politik gentemot Makedonien, Kroatien och Turkiet
In this essay the aim was to investigate how the EU is trying to function as a democracy promoter in three particular countries, the so called candidate-countries Croatia, Macedonia and Turkey. The aim was also to analyze if there exist any differences in how the EU functions in these countries as a democracy promoter with a focus on how acts of democracy promotion is taken place. In order to fulfil the purpose of the essay two questions were addressed, how does the EU perform in promoting democracy in the three candidate-countries Croatia, Macedonia and Turkey? And also, is it possible to identify any differences in how the EU functions as a democracy promoter in those three countries?The method used to fulfil purpose and answering research-questions was qualitative text-analysis. The results of the study were that the EU does perform in a number of ways to promote democracy in the three countries. The main differences are that the EU is using primarily political tools in Croatia and Macedonia which are channelized top-down and economic tools in Turkey channelized mainly top-down to promote democracy.
"hund, hund arm, hund arm boll" : En studie om användningen av fonologisk minnesstrategi kopplat till ordproduktionshastighet hos ungdomar med utvecklingsstörning
Tidigare forskning har visat att barn med typisk utveckling går från en visuell strategi till en fonologisk. Huruvida denna utveckling sker hos personer med utvecklingsstörning är oklart. De flesta forskare är överens om att dessa personer har en nedsättning i den fonologiska loopen. Om denna nedsättning beror på strukturella avvikelser eller utvecklingsförsening är forskarna inte eniga om. Det är även oklart var en eventuell strukturnedsättning skulle sitta.
Multitorget :
This is a final project which makes up 20 credits at the Landscapearchitecture programme at SLU in Alnarp. The thesis is design based.
My final project is comprised two parts; of a competition entry for ? A New Square in the Centre of Täby? as well as a theoretical study that derives from the competition proposal. The competiton itself was announced on March 1st 2007 with the final hand-in date on May 28th 2007.
The program of the competition asked for a flexible urban square that offers a diverse range of activities that can be used during both night and day, all year around. I became interested in the term ?mutlifunctionality? and I went on to use the subject as a base for my design approach.
Standardiserande CAN drivrutiner
This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.
