Demokrati, ett uppdrag för skolan : En implementeringssudie angående demokratiuppdraget i skolan

The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.

GPGPU : Bildbehandling på grafikkort

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..

En studie av två invänjnings-modeller i förskolan. :  3-dagars och två-veckors modellerna 

I have made a research about two different methods for introducing small children to Nursery School/Kindergarten. I choose to do this as I have found very little about this in the literature we have studied during my education to become a pre-school teacher.This period in the life of very small children and their parents is a big change in their daily life. The more traditional way to start pre-school is to do it very gradually during two weeks, the two-week method. This means that the parents visit the pre-school together with their child for a very short time, about one hour the first day. After one week they leave their child with the staff for about an hour and at the end of that week they try to leave it full time (6-8 hours).

Utvärdering av 3dvia Composer : -För arbetsinstruktioner och beredning

With recent technical development computer aided design and manufacturing has taken amore important role in the product life cycle. New business segments such as Product/ServiceSystems and remanufacturing is emerging. This development demands better control of theproduct data throughout the entire product life cycle. Computer aided design is widelyrecognized and used within the manufacturing industries and in recent years the importance ofDigital manufacturing has increased. One part of Digital manufacturing is paperlessproduction which involves all orders and working instruction shown for example on a screenrather than on a piece of paper.

Införandet av CASE: en fallstudie i två konsultföretag

I detta arbete har vi undersökt vilka faktorer som är viktiga för ett lyckat införande av CASE verktyg i en organisation. I arbetet har vi utgått ifrån de faktorer som teorin förespråkat och jämfört dessa med den empiri som vi har undersökt. De faktorer som vi har funnit i litteraturen har vi delat in i grupperna organisatoriska faktorer, utvecklingsfaktorer och stödjande faktorer. Vi har funnit att hanteringen av dessa faktorer i många fall skiljer sig mellan teori och empiri. Utifrån undersökningen har vi dragit slutsatsen att utvecklingsfaktorer har varit den grupp av faktorer som har påverkat införande mest i de undersökta företagen..

GA-elevernas integration på Elinebergsskolan

The purpose of this essay was to find out whether the students, which had moved from the school of Gustaf Adolf to the school of Elineberg, had been integrated into their new environment. We chose to analyze the degree of integration concerning their schoolwork, how they interacted with the students from the new school, the school of Elineberg, and their level of wellbeing in their new school. We have used two methods, surveys and interviews, to be able to obtain the general picture of how the integration of the students has succeeded.Our conclusions are that the student has adapted well in their new school despite many obstacles along the way. Our essay shows that the students get along well with their new school friends during class, but they don´t socialise in their spear time. Although they seem to have accepted the closure of their old school some students express that they wish the school would be reopened.

Självmord och självskadebeteende : en studie om självmord och självskadebeteende inom Svensk kriminalvård 2002- 2012.

During the period 2002-2012, 74 people committed suicide within the Swedish judicial system. During the same period of time 702 self-destructive actions and suicide attempts were reported. The purpose of this work was to investigate and illuminate the causes which are responsible for individuals committing suicide while in custody or in prison. The theory of this  work is an ethnographic study of a special social context. A study of literature, statistics and earlier scientific research was used in this study.

Det virtuella ärendet - en storbildsvision för arbete på ett samhällsbyggnadskontor

Denna rapport handlar om arbetet med detaljplaner på ett Samhällsbyggnadskontor. Den försöker svara på två frågor. Hur kan man designa integration av olika applikationer, medier och work practices? Är metoder från Participatory Design (PD), Etnografi och CSCW lämpliga för att utforma en sådan designprocess? I min studie har jag använt mig av dessa metoder för att studera arbetet i sin kontext på kontoret, genom situerade intervjuer och observationer. Jag höll även en designworkshop tillsammans med några medarbetare på kontoret.

Sudokulo?sare: Ja?mfo?relse av ko?rtider fo?r backtracking och ma?nskliga strategier

Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .

Pseudoslumptalsgenerering : En studie av pseudoslumpsalgoritmer i allmänhet med fokus på C++11-biblioteketRandom samt implementation av en modifierad XORShift

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..

Det handlar om tur: en kvalitativ studie av rättsprocessen vid kvinnofridsbrott

The purpose of this essay was to examine the experience of the judicial process concerning domestic violence from the perspectives of abused females and from some of the authorities and organisations which meet these women. The essay investigated several views of the judicial process in order to obtain a wide perspective. It responded to the following questions:- How are abused women treated by the authorities and organisations?- Are there enough resources and knowledge among the authorities and organisations?- Is there any collaboration between the authorities and organisations which the female meets in the judicial process and if so, how does it look like?- What does the aspect of security of person look like for the women which have been exposed to domestic violence?- What in the judicial process is important for the women's ability to move on in her life after experiences of violence in a relationship?This study was based on a qualitative method, where the interviews constituted of empirical material. The essay was based on interviews with two females who have experiences of violence in a relationship, two social workers from Kvinnojouren in Lund, two social workers from Kriscentrum in Lund, one lawyer, one prosecutor, one policeman and one social worker from Kvinnoforum in Lund.
