Recreation in the urban countryside
Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).
Kan du bevisa det? : En enkätstudie av gymnasielärarens förhållningssätt till matematiska bevis
Practice of mathematical proof increase the understanding of mathematics anddevelop creativity skills, problem solving, communication, logical thinking andreasoning which are all important tools not only within the subject of mathematicsbut also important tools for the society in which we are living. The aim of this projectwas to investigate whether it is accurate that proof and proving has a subordinate rolein mathematic education in the upper secondary school in Sweden. This was done byconstructing of a digital survey that was sent to approximately 100 practicingmathematics teachers in a normal size city located in the middle of Sweden. Theresults of the survey show that the teachers consider themselves comfortable withtheir own skills in teaching proof. Paradoxically, the results also show that there is alack of teaching of proof and proving in the upper secondary school, although the newcurriculum puts more focus on proof and proving..
"April, May, June". En mönsterkollektion för textil.
I have worked with patterns for textiles, and the goal of the project was to makethree patterns in one colorway. My wish was that the patterns would be relatedeither in motif or colorway, or both. I wanted the patterns to be seen as a minicollection. My aim was to make three patterns that would serve as home textiles.I decided to print the patterns digitally on fabric, but also to customize the designof the pattern repeats to be printed in rotary printing. I wanted to work within thelimits of what is possible to produce in terms of colors and repeat sizes.One of my goals with the project was to clarify for myself what the essence of mydesign is, and to create a collection that reflects me as a designer.
Vad är ett gott samhälle? : En kvalitativ studie av gymnasieelevers uppfattningar kring vad som utgör ett gott samhälle, i förhållande till kursplanen i religionskunskap 1.
This essay is an analysis of how Swedish sixth form students interpret ?a good society?,an expression which is part of the main content of Religion1, the mandatory course inreligious studies. It is based on a a survey asking 198 students to define and reflect onwhat a good society might look like. A hermeneutic method has been used to analysetheir answers in relation to regulations and research.The conclusion is that although most students show themselves able to reflect on whata good society might be, their ability to use ethical theory and concepts required by thecourse?s grading criteria is limited.
Hur löser elever med kombinerade läs-, skriv- och matematiksvårigheter matematiska problem?
Syftet med denna studie är att ge en insikt i hur elever med kombinerade läs- och skriv och matematiksvårigheter tänker och resonerar vid problemlösning.Tre elever i år 8, som alla ingår i samma specialundervisningsgrupp i matematik, har arbetat med olika typer av matematisk problemlösning, såväl individuellt som i grupp. Med utgångspunkt i deras arbete skapas början till en grundad teori.I forskningssammanhang behandlas ofta denna kategori elever (med kombinerade problem) som en enhetlig kategori som jämförs med t ex elever med enbart matematiksvårigheter, normalpresterande elever osv. Denna undersökning visar dock att de svårigheter eleverna uppvisar är av mycket olika karaktär.Studien omfattar tre delar: en presentation av fältstudien och resultaten från denna, en metoddel innefattande en pilotstudie som koncentreras på datainsamlingsmetoden samt en omfattande litteraturstudie som behandlar problemlösning och inlärningssvårigheter..
Betongbjälklag med limmad matta : olika behandlingars effekt på alkalitet, fukthalt och emissionsbildning
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).
Den vanmäktige allsmäktige : Framställningen av Gud i två senmoderna svenska romaner
Both contemporary research in History of Religions and current public debate tell us that Christianity as a religious form is challenged in today?s society. Nevertheless, Christianity is often present in secular artistic expression such as fictional literature. The purpose of this paper is to examine how God is portrayed in two late-modern Swedish novels, Djävulen och Gud by Mare Kandre (1993) and Boken by Niklas Rådström (2013).The examination is based on a hermeneutic method using close reading in order to answer the questions asked. The result of the examination shows that God in the late-modern novels is portrayed as a figure with shifting emotions, and in both novels God goes through changes which are in some ways similar.

The purpose of this study was to find out what the educators view on the working method Matte på burk in preschool looked like. I also wanted to find out what the educators thought about the working method. My questions are:How does the educators in preschool experience the method Matte på burk?What do the educators in preschool believe that Matte på burk can give the children?The study was carried out through a qualitative interview study with six educators. During the interviews with the educators it became apparent that the method not only focused on mathematical exercises.
Hur kommuniceras värderingarav matematik i kursplanen? : En diskursanalys av värderingar i kommentarmaterialet tillkursplanen i matematik.
This study is part of an international project, The Third Wave Project. The project aims to conductstudies with students of different cultures to see what they value as important in mathematics andmathematics learning. Part of the project involves carrying out a survey, the WIFI study. The WiFistudyaims to examine values of mathematics teaching that may affect student learning. The valuesthat are examined in this study are based on the mathematical values which are described by Bishop(1991).
Optimal bredbandig vågform framtagen genom generaliserad osäkerhetsfunktion
The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.
Kvinnor och män i reklam : En kvantitativ innehållsanalys om kvinnor och mäns framställning i modemagasin ur ett genusperspektiv
This study is about gender stereotypes that occur in the magazines of ELLE and KING's advertisements in 2014. The purpose of this inquisition is by using a gender perspective to examine the interpretation of women and men, compare how they relate to the traditional gender stereotypes. To answer our purpose of this study, a selection of 400 advertisements were analyzed based on it's content and visual expression. Through a content analysis, we could measure the frequency of 18 variables and put them in relation to each other to grasp the differences that exist between the genders. The results are presented in bar charts based on the variables that proved most interesting outcome between the genders.

Svårigheter i matematik för elever med svenska som andraspråk : Lärares syn på problem och möjligheter
In today?s society teachers will face students of foreign origin. It is up to the teachers to help these students gain the knowledge they need to flourish in society. Despite the fact that mathematics is a universal topic with high status in many countries, studies have shown that mathematics is a subject where a large proportion of foreign students fails. The purpose of this study was to see wherein the problem lies and describe teachers' perceptions of the barriers and the opportunities in mathematics for students with Swedish as a second language.
Simulated Annealing : implementering mot integrerade analoga kretsar
Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.
?Matematik finns överallt och ingenstans? : Med fokus på pedagogernas arbete
The aim is to find out how teachers apply the knowledge they get from mathematics pilots in preschool and from mathematics developer in the municipality, as well as how they work further towards the children with mathematics.The study is based on qualitative interviews with two teachers, one mathematic pilot and one mathematic developer. I used the semi-structured interview questions.The results show that teachers believe that mathematics pilots will inspire the teachers in their work with mathematics in preschool. One of the teachers who were interviewed said:?Mathematics pilots should be those that have the strongest glasses and coming up with new ideas and they push the rest of the teachers in their work with mathematics in relation to children in preschool?.The teachers use the correct terms for mathematical concepts with the children. They also stressed how important it is to point out to the kids that it is mathematics that they are doing.The conclusion of the study is that the teachers agree that it is their approach towards the children that is important and how they can lead the children?s interest of mathematics forward.
