Datorer i förskolan - barns nya kultur : barnvakt eller ett pedagogiskt hjälpmedel
In this essay I have chosen to explore how computers are used in preschools. The study was done as a survey. How does preschool seize the children´s culture? In today´s society ICT and computers are a big part of children´s everyday life and reflects on their upbringing.Since I am using computers as a pedagogical tool in teaching the children at my preschool, I find this topic interesting to explore.Are the teacher´s using computers for an educational purpose with the children at preschools or are they using it in other ways?Do the teachers think they have the required knowledge to computers usage in teaching the children in a pedagogical way?What is the teacher´s attitude towards computers in preschool?The essay starts with a introductorial background section where I talk about my own experiences of using computers with the children in my preschool, and then referring to the society then and now, school law, curriculum, teachers' computer skills, media situation amongst children and young people, computer use in preschools/schools and health effects. I have composed a survey based on the answers of 50 teachers in 30 different preschools and in nine different municipalities.The result of the survey is reported and concludes with a part of discussion, where the results are put up against the introductorial background section.

Typer av brus : Implikationer för den auditiva komponenten i ganzfeldstudier
Ett vanligt förfarande i parapsykologiska s.k. ganzfeldexperiment är attmed hjälp av vitt brus, som spelas upp i hörlurar, försöka omslutaförsökspersoner i ett slags totalt och oföränderligt perceptuellttillstånd. I föreliggande studie undersöks konsekvenserna av attanvända vitt brus som bakgrundsljud. 30 försökspersoner har lyssnattill åtta ljudslingor innehållandes fyra typer av brus vid två olikaljudnivåer, för att sedan i ett enkätformulär uppskatta hur dessa ljudpåverkat dem. Resultatet visar på signifikanta effekter av så välbrustyp som amplitud, och dessutom en signifikant interaktionseffektdem emellan.
Folkbibliotekariers användning av sökverktyg på webben i referenstjänst
The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

Introduktion av division för alla - en learning study i åk 3
My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods
for estimation of the down channel (base station to mobile subscriber) in
Wide-band Code Division Multiple Access (WCDMA).
The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is
a conventional method that bases the estimates on data that is known to both
sender and receiver, so called pilots. The second method, Decision Directed
Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data
for estimation.
Simulations show that DDCE, in comparison to OFCE, does not attain an
improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An
improvement is only seen when the BER becomes much lower than what is common in
real situations.
In conclusion DDCE is complicated, involves many mathematical operations and
gives insignificant improvement of SNR when BER takes common values. It is
legitimate to question if it is possible to use the method in a real mobile
phone system..
JOBBIS - En ny lekplats på Universeum
I did my degree project together with Universeum AB. The project had the work title: children?s world and the aim were to give children between 3-8 years old a place that was especially made for them. With their interests and needs in mind the area should trigger play but also learning through a well planned pedagogical environment.I did this project because I thought this was an excellent opportunity to really practise my new gained skills I had learned during my two years in CCD (Child Culture Design). It also gave me the opportunity to actually see how well my knowledge was working when it was put to the test, and I did learn a lot from this.Together with a crew of 6 people I developed and designed the area.
En vindkraftparks inverkan på Gävle Energis elnät
The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.
Unga ledares ledarskap - en kulturell fråga
Culture is seen as an abstract phenomenon, not easily defined. It is cathegorized as something that affects every person, though it is seldom described how. This study adress how culture, in the form of basic assumptions and accepted behaviors and ways to think affected how young coaches formed their leadership under the influence of their organization. The possible implications for the importance of knowing about ones culture in an organization affect both the recruitment process in organizations and what the organization stands for and what is conveyed through values and ways to act in the organization. The purpose of this study was, through the use of semi-structured interviews with young coaches and organizational leaders and a review of policys, to get the perspective and experiences of young coaches regarding cultural influence on their leadership.

Direktsamplande digital transciever
Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.
