During this master thesis, wear and friction properties for the high-temperature alloy Kanthal APMT were studied. The results were also compared to 253MA. The initial tests showed, among other things, that the surface fineness of the muffle tubes matters in real applications like conveyor belts. A 253MA-sample wear-tested against a 253MA-tube showed lowest wear at 900°C while a pre-oxidized APMT-sample wear-tested against a APMT-tube had the lowest mean value of the friction force at 1100°C, compared to all other tests..

The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old. In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.

This scientific essay starts in a story where you get to follow me in my work by three situations with creative problem behavior at the special school where I work. The story culminates in a dilemma where I ask myself questions about how I look at my actions and my thoughts about the student. I break down and put these thoughts into three questions: What is my student's perspective and how will it affect my actions? How can I explain my actions and attitude of the student from ethical perspective? How do my practical knowledge look like in the narrative situations and why do I act like I do?My approach is to get answers to the questions by the reflection of the text itself, the reflection group and supervisors, as well as through literature that I find relevant to the issues. The process is like a pendulum motion between text, reflection and new understanding.I look at my situations based on psychological theories about the treatment of persons within the autism spectrum of problems creative behavior.

This thesis describes a further development of an existing prototype named Automatic pin bone remover. The further development was requested from the Swedish consulting firm ATM AB. The request of automatic pin bone removers is high and has the potential to be a worldwide leading product.The goal with the thesis work is to further develop an existing prototype. In order to achieve the goal a pre-study of the prototype had to be made in order to define a customer demand specification. The thesis work is then continued by a function analysis which differs from a conservative one.

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

In addition to all our soldiers and officers who do military services abroad there are a lot of people who are affected by their choice to contribute, namely their next of kin. This report deals only with those who are next of kin to those who perform service abroad. The purpose of this study is to investigate the relatives' need for emotional and social support as well as practical and economical support. The main question is What kind of practical/economical and emotional/social support do close relatives require when a relative does military service abroad? The method used in this paper is a qualitative research interview.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

In this study I have examined how narrative techniques can be used to promote the reading value and readability in information. My focus has been on the communication-agency Mandoly?s information-brochure which function is to inform other companies about their own potential for development in collaboration with Mandoly. The purpose with this study is to examine how it is possible to increase the reading value in order to engage the target group. In my study I have used four methods: analysis of Mandoly?s old information-brochure, literature studies, a qualitative interview, and an user test.

The purpose behind this work was to investigate whether I could from a practical approach to create desire for mathematics among students in primary schools. I wanted also to find out how students feel about their current mathematics teaching. By introducing an equation game, and interviewing students to find out their perception of their mathematics teaching, I was able to answer my questions. What I came to was that through a practical and laboratory work, I could create an enjoyable educational opportunity in mathematics. Then during the interviews I also learned that students had not a pre-determined negative attitude towards mathematics.

The goal with this project, was to explore the producing of a musicvideo with a synergistic focus in a practical way. Beside the practical work with the recording and editing of music and video, I wanted to explore the sound engineers role in such a project? To my help I had the video producer Hannes Knutsson from the small film- collective Lefvande Bilder and the singer, guitarist and songwriter Conny Flink. The result of my work is a musicvideo published on the internet website YouTube and the report of the making of it along with my work around the question above is published in this report. The name of the recorded and filmed song, written and performed by Conny Flink is ?My Way?. .

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.
