This research overview examines what research says about upper secondary school students' difficulties with complex numbers. The three main areas covered are general difficulties with complex numbers, how to teach the subject, and whether the history of complex numbers can be beneficial in this teaching. A historical deep dive into the history of complex numbers is also included to further investigate this idea. The results show that upper secondary school students struggle with complex numbers in various ways. The name of the subject creates a negative connotation, as it is initially perceived by students as fictional and complicated. Furthermore, a consequence of the inherently abstract nature of complex numbers is that gaining a comprehensive understanding of them is challenging.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

ABSTRACTPurpose/Aim: This essay aims to investigate what picture (obvious and hidden) of men and womens equality in our society that is to be found on DN Debatt.Material/Method: The material consists of 175 articles from DN Debatt during 2004. A content analysis and a rethoric analysis has then been used as a method of analysing the material.Main results: Men are much more represented on DN Debatt then women. The underlying picture of men and women that is presented sees men as being the ones who are in charge of all the important and ?big? decisions and questions in our society. Women on the other hand are pictured as, although they have reached higher positions in society, the ones who to a high degree focus on closer and more socially important issues.

In this paper, I have conducted a study of what perspectives educational drama has in theory and practice. The study aims to show an example of how and out of what perspectives educational drama is a part of the school?s activity at a geographically distinct school, from kindergarten on to primary and secondary school years. The general attitude of the faculty and their arguments for and against drama constitute the major aspects of this study, which has been carried out through qualitative interviews at a school in Skåne. The results were that pre-school focuses on teaching drama to develop communicative abilities amongst the students (art educational perspective) while secondary school seemingly abandoned this approach and focuses more on using it for personal development, increasing empathy and understanding of other people by taking it to a more emotional level in order to affect for example moral values of the students.

AbstractThis study focuses on three generations of Kurdish women's view on honor. The study is a qualitative research based on three individual interviews. The aim of this study is to examine how three generations of immigrant women from a culture of honor is influenced over time by the majority culture and its values together with how these women affect each other mutually both consciously and unconsciously within the family. The study is based on two questions: What does"honor" mean to the three generations of women who are Muslim and Kurdish? Did these three generations of women?s idea of honor change over time as they have lived in Sweden? Results of this study have shown that the concept of honor has its focus on the woman's body, sexuality and chastity.

This study is about quantum physics and the role it can play in a religious perspective. I intend to examine how moderna physics may be related and understood as New age and Myths. My material consists of two books in the new age genre: "The Tao of Physics" by Fritjof Capra and "The Quantum Self" by Danah Zohar. My first two question to these books are which 1) religious and 2) scientific content they have. My other questions are too 3) investigate and demonstrate how these books are new age and 4) to exanine how the books can function as myths and adopt mythical features.

This paper aims to examine how children who have experienced violence against their mother experience their school and if the school somehow can compensate for the vulnerable situation of the children?s home situation. The data is an already collected material there interviews with abused children are done. The results presented consist of the previous research in the area where the empirical material analyzed from the developing ecological theory and based on children's different abilities to master life and then give an voice to the collected research. The results showed that if the violence in the family does not affect the child's sleep or the parents do not prioritize enough for the child to get the sleep he/she needs and that the child is not serious difficulty concentrating, it seems that children can use school to learn and enjoy this learning.

Under de senaste åren har en ny trend inom spelindustrin uppstått då en stor del av spelen har gåtttillbaka till de tvådimensionella miljöerna som var vanligare i tv-spelens barndom, detta tack vareatt mobiltelefoner och deras spel har tagit allt större plats på marknaden och de är oftatvådimensionella på grund av sin begränsade hårdvara. De tvådimensionella spelen har enligttradition inte haft någon dynamisk ljussättning, utan de har bestått utav färdig grafik medförutbestämda intensiteter vilket gör att spelen kan se platta ut.Men inom andra områden av spelindustrin, framförallt tredimensionella spel, har utvecklingen avdynamiska ljussättningsmetoder kommit långt. Problemet med dessa metoder är att de kräverobjektens normaler, vilka normalt inte finns tillgängligt i tvådimensionella bilder.Idag är mobiltelefonerna kraftfulla och klarar av mycket tyngre beräkningar än vad de gjorde förbara några år sedan. Därför undersökte vi möjligheten att implementera dynamisk ljussättning i etttvådimensionellt spel på androidbaserade mobiltelefoner. För att genomföra detta krävdes också attvi undersökte metoder för att generera normaler för tvådimensionell grafik.För att ett fullständigt spel skulle kunna skapas så implementerades också saker somkollisionshantering, artificiell intelligens och procedurell generering av banor..

Abstract- Stress, conformity, groups and self-worth in high-school girlsThe aim of this questionnaire-survey was to investigate the experience of stress and symptomsof stress in high-school girls, and to examine if the experienced symptoms of stress could bepredicted by groups, self-worth and conformity. Another purpose of this study was to describethe girls own thoughts concerning these factors. 80 girls between the ages of 15-18 yearsanswered the questionnaire. The results showed that stress could be predicted by theexperience of conformity, but not by the experience of belonging to a group and self-worth.The most common symptoms of stress were tiredness, problems to concentrate and headache.The girls reported that they thought that girls of their own age were ?slutty and cocky?, andthey thought that it was important to look good, but at the same time many girls were happyabout themselves and they had realised that they had to live with who they are.Keywords: high-scool girls, stress, groups, self-worth, conformity.

Every day consumers are bombarded with different marketing messages from all possible directions. At the same time consumers starts to actively and consciously avoid these messages. Therefore, marketers have to start thinking outside the box and find new ways to get consumers' attention. One of these methods is called guerilla marketing. The strength of guerilla marketing is its way to be unexpected and unusual.

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.
