Elever med diagnosen ADHD i skolan : kvalitativ studie om 4 lärares erfarenheter och förhållningsätt till diagnosen i årskurs 1-7
How teachers teach children with attention difficulties. This is a qualitative interview based on the experiences of four teachers. I want this study to examine teachers' experience and views about ADHD diagnosis. I would also like to find out what teachers do and think about the practice which surrounds students with ADHD. How to formulate and think of four active teachers about ADHD? What are the implications of the diagnosis perceive the four teachers interviewed that the diagnosis must for students? Among the measures that consider the four teachers interviewed are most effective for students with ADHD because they provide an equal education? Those questions are addressed to specifically learn about how they proceed in their activities.
Bildanalys för navigering i autonoma sensor-platformar
Det bör vara möjligt att skapa verktyg för att beskriva scenarion och med hjälp
av tillgänglig
mjukvara för visualisering kunna spela upp både verkliga och simulerad bilddata.
Detta examensarbete beskriver hur några sådana verktyg tagits fram. Till
förfogande fanns en
stor mängd bilddata, insamlad på ett militärt övningsområde som dessutom finns
representerad
som en syntetisk omvärldsmodell. Insamlingen gjordes med en UAV (Unmanned
Aerial Vehicle)-
prototyp, som var utrustad med videokamera, IR-kamera och
tröghetsnavigeringssystem. För
att simulerad bilddata skulle få ett verklighetstroget intryck placerades
markfordon ut i den
syntetiska modellen på exakt samma position som under fältförsöken.
Markfordonens position
mättes in med DGPS och UAV:ns hastighet, position och rotation bestäms med GPS
och tröghetsnavigeringssystem.
Resultatet, i form av lagrad tröghetsnavigerings- och sensorstyrnings-data,
ges efter en Kalmanfiltrering och blir vanligtvis noggrannare än vad som
erhålls från de respektive
delsystemen.
Tyngdpunkten i arbetet låg i att ta fram Matlab-funktioner som plockar ut rätt
vy vid rätt
tidpunkt och åskådliggör detta på ett tydligt sätt, samt att placera ut
markfordonen enligt
de givna koordinaterna.
Kontinuerlig autofokus för IR-kamera
Detta examensarbete har omfattat utveckling och implementering av en kontinuerligautofokus för en IR-kamera. En studie av olika tekniker för traditionella kameror hargenomförts, och därigenom har olika metoder vilka även passar för en IR-kameraframkommit. En traditionell videokamera har också införskaffats och analyserats för attförsöka få ledtrådar till hur den kontinuerliga autofokusen fungerar i en sådan.Två tekniker för kontinuerlig autofokus har utvecklats, en baserad på en ultraljudssensor ochen som kombinerar denna sensor med bildbehandlig. En kamera, FLIR P660, ochultraljudssensorn, LV-MaxSonar-EZ1, anslöts till en PC varigenom kommunikationenskedde. Ett användargränssnitt togs fram i Matlab, vilket gjorde det möjligt att styrafokusmotorn i kameran och registrera avståndet från sensorn.

Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence
The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.
Elitfotbollsföreningars Organisation
The overarching purpose is to describe how elite soccer clubs choose to structure their sport oriented organization. This purpose leads us to questions and areas involving sport managers, casting, operational directions, education and goal setting in sport.The results in this thesis are based upon a qualitative investigation of sport managers in Swedish elite soccer clubs. To strengthen the reliability in our choice of method we will fortify it with theories that reflect methodical choice.Our conclusions in this thesis is that one can see a clear difference in how the clubs choose to structure the casting and operational directions within their organization. We have also noted that there is a clear distinguish between the levels of education amongst sport managers in Swedish elite soccer clubs..
Modellering och simulering av ensemiaktiv motorcykelstötdämpare
Hydrauliska stötdämpare har länge varit en central komponent i fordonsbranschen och de påverkarväsentligt komfort, köregenskaper och väghållning. Var och en av dessa egenskaper kräver olikadämpningskaraktär, vilket med en konventionell dämpare leder till kompromisser av t.ex. komfort ochväghållning. Dessa kompromisser har lett till utvecklingen av stötdämpare med elektriskt ställbardämpningskaraktär som ersätter konventionella dämpare i flera segment. Möjligheterna att förbättrafordonens egenskaper är stora men val av reglerstrategi är avgörande för dämparnas prestanda.Detta arbete behandlar en semiaktiv CES-dämpare från Öhlins Racing och syftet är att undersöka hurregleringen kan förbättras med avseende på precision och snabbhet med hjälp av modellbaseradreglering.
Större svartbagge Upis ceramboides i norra Hälsingland : förekomst, substratkrav och effekter av skogsbrukets naturvårdsåtgärder
Many wood living insects are considered threatened by modern forestry due to the reduction in amount of dead wood. During the last decade various methods have been used to enhance the quantity of dead wood in managed forests. However little is known how and if these methods are aiding saproxylic insects. The threatened tenebrionid beetle, Upis ceramboides, is already extinct in southern Sweden. It develops in white rotted dead birch (Betula spp) and requires sun-exposed sites.
Reglering av vridbord
This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.
Utvärdering av ett optimeringsprogram för produktionsplanering.
The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .

Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :
High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals.
Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.
Arbeta inteam(t) : En studie om team och teamarbete
AbstractThis is the paper you should read if you want to know more about working in team. Teamwork is a way of working and it increases more and more among societies and companies today, but it is not quite clear what the diffrences is from working in groups. We have in this paper tried to clear out the differences between groups and team, and we have also tried to give an oversight of how to work in team in organizations. Cultures of organizations, leadership and power and also development of qualifications are big parts of an organization´s daily work, and we have explained these concepts from a teamperspective.We have, in this paper, done interviews with people that have been in contact with the central consepts that we use. And then we have analyzed their answers with help from litterature, which we have closely studied, thereafter we have presented our results.
Normbrytande beteende : en studie av uppfattningar och resonemang hos kuratorer på högstadieskolor
The purpose of this paper is to investigate how staff at secondary schools are thinking and reasoning about notifications to social services based on norm breaking behaviors in students. To find this out five qualitative interviews has been made with counselors in two public schools and three private schools in Örebro län. The results show that there is no clear definition of what norm breaking behavior is which making the reasoning difficult. There are clear procedures for the staff to dealing with norm breaking behaviors but they do not know when they will be applied. The decision to report behavior to the social service is usually not taken individually, it is a result of several people?s views and experiences.
Skolan, en arbetsplats att trivas på! : en studie om framgångsrika skolledares syn på lärares psykiska hälsa
Aim and questionsThe aim of our study was to increase knowledge about successful school managers' views on teachers' mental health and their own work regarding this subject.In what ways do the school manager work preventive with measures on teachers' mental health? How does leadership affects teachers' mental health? What factors create mental health among teachers? MethodIn order to answer the questions, we have chosen to use semi-structured interviews. To get in touch with schools that have been successful with their work with the teacher's mental health, we have made a targeted step wise sample where we contacted the primary managers of six randomly selected municipalities in Stockholms län. In total six school managers have been interviewed. The empiric data were thematized and analyzed based on the demand-control-support model. ResultsAll the interviewed school managers agreed to that the concept of mental health is about feeling good, about balance in life and to feel safe.
