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).

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.

Snö och permafrost är två interagerande komponenter i Kryosfären. Studien undersökersnödjupets representativitet vid marktemperaturmätningar under snötäcket (BTS) föridentifiering av permafrost i Tarfala, norra Sverige. Snödjupsmätningar har utfördes itvå korsande 20 m transekter i nordsydlig (NS) samt östvästlig (ÖV) riktning utifrån enBTS-punkt. Totalt har 37 BTS (snödjup > 80 cm) med tillhörande snödjupsmätningarregistrerats och analyserats. Snödjupet varierar både lokalt kring mätpunkten ochregionalt i mättransekter men är ändå ett representativt snödjup för en punkt.Representativa BTS, sett ur ett snödjupsperspektiv, bör registreras på platser medmåttlig snödjupsvariation som på platser med homogent markunderlag, vindskyddadeområden, lä bakom ryggar och sluttningar vinkelräta mot den dominerandevindriktningen.BTS provplatser bör också ta hänsyn till de mest förekommande klasserna avparametrarna altitud, sluttning och slutningsriktning för att erhålla representativa BTS.Detta baserat på jämförelse mellan två strategier för insamling av BTS genompermafrostmodellering mellan två dataset.

Trafikverket vill ta reda på hur de skaimplementera BIM (Building information modeling) som ett arbetssätt i sinorganisation vid projektering, byggande och förvaltning. Syftet med det härexamensarbetet är att ta reda på hur Trafikverket kommunicerar med BIM-modelleridag och hur man kan utvecklas.Det är få människor i anläggningsbranschen som idag har erfarenhet av att arbeta med BIM. Även i de projekt som jobbar med BIM idag så behövs det alltid en BIM-samordnare som håller i trådarna. För att få ett bra slutresultat så måste kommunikationen i ett projekt fungera bra. En förutsättning för detta är att alla inblandade parter har samma mål med projektet, t.ex.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

 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.

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.

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.

The purpose of this study is to examine the importance of a working laboratory in mathematics education, how it influences students? learning and the confidence the teacher has in the laboratory component. Focus has been placed upon the advantages and disadvantages that could follow in the working method.The method used in this essay is qualitative in order to answer all the questions that arise along the way, and in order to use this method in interviews. The interviews that has taken place has been with five class teachers that are currently teaching at a elementary school between the years of 1-5. The purpose of this study has been answered by using its literature and the qualitative method with the class teachers.The results of the research show that teachers express gratitude towards the method in use for mathematics studies.

This thesis was performed at Indusec ABin Stockholm. Indusec AB is a companythat develops security solutions.Together with the Police of Sweden theyhave gotten the assignment to develop anapplication based on one of theiralready existing product Inferno soundbarrier. This application is supposed tobe mounted on a ballistic shield thatthe police use, the application consistsof a speaker box (the sound barrier) anda trigger with wire. The trigger withwire is the part that will be addressedin this thesis. The application willthen be used as a tool to surprise atarget at various skirmishes.The project consists of three majorphases, pre-study, concept generationand modeling.

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

The purpose of this study was to examine young offenders? attitudes towards crime, and to the penalty they have been sentenced to as juveniles. More specifically its aim was to examine an intervention program called Galaxen, specifically used  to deal with  juveniles  in Växjö. This intervention program consists mainly of conversations with social workers from social services,  aiming  towards  better  self-awareness  and  the  ability  to  understand  the  consequences  of one?s actions.

Syftet med denna studie var att undersöka hur gymnasieelever översätter mellan tre matematiska språkformer (symbolspråk, matematiskt språk och vardags-språk). Studien använde ett slags test, en kunskapsdiagnos, för att undersöka detta. Gymnasieelever från samma program i tre olika årskurser fick möjlighet att delta i studien. Diagnosen var uppdelad i tre översättningsområden: från matematiskt språk till symbolspråk, från symbolspråk till matematiskt språk och till sist från symbolspråk till vardagsspråk. Resultatet visar att gymnasieeleverna, oavsett årskurs, har problem med översättningarna.

Denna rapport tar upp teorier och metoder kring användbarhet i skapandet av en Flash-applikation. Rapporten beskriver steg för steg i skapandeprocessen, hela vägen från att ta fram behov och användningsområde till att skapa innehållet och slutligen en utförlig redogörelse för hur applikationen sammansätts. Metoderna som använts är huvudsakligen ITK (Identity Tool Kit) och scenarier enligt Alan Cooper. Vidare har metoder för hopsättning och visualisering av applikationen använts med stöd av Nielsen och Raskins användbarhetsprinciper. Resultatet visar att för att använda ITK i syfte att kartlägga en verksamhet, kräver detta en stor förståelse och modifikation av denna.

Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.
