Utbildningen av nyanlända elever i gymnasieålder : Nationella utredningar och lokalt arbete i Södertälje och Malmö kommun
The purpose of this thesis is to study the education of newly arrived 16-20 year old immigrants and how their education in the towns of Södertälje and Malmö matches up with national inquiry into the subject.The research questions in this thesis are as follow: What type of documents shape the work with newly arrived students? What's the preferred development surrounding the education of the newly arrived students nationally? What does the latest study, which is a proposed reform of the Gymnasium system, say about the education of newly arrived students?How does the local work connect with proposals of national investigations? Do the cities take responsibility for evaluating the education of newly arrived students? From arriving to graduating, what does the road to graduation look like for a newly arrived student? What is the curriculum of a newly arrived student?The methods used here are studies of investigations made primarily by Skolverket (The National Agency for Education) and Myndigheten för skolutveckling (The Agency for Development of Education), studies of local documents such as annual reports of quality and promotional material for programs at local Gymnasiums (High Schools), and interviews with local persons in charge of shaping the work with newly arrived immigrants.This thesis has not used theory as a foundation for structuring the analysis, but postmodern theory and the use of three dimensional power inspired the thesis.The conclusions made focuses on the future of the education for these teenagers at large and makes connections between the national investigations and the local work with immigration education.In order for these teenagers to be allowed to join the Swedish national Gymnasium, they need to learn Swedish, and integration seems to be an important part of learning Swedish quickly. .
Geografisk prioritering av CTI-utrustad virkestransportkapacitet
Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.
Flygteknik : Konceptstudie av ett obemannat flygplan
Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

Chassiintegrerade lastceller : Installation i fjädersäte på Scania tandemboggibakaxlar
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

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.
En jämförelse mellan TLS och UAV-fotogrammetri : Inmätning av hårdgjorda ytor
At present day there are several different methods for measuring of paved surfaces.The most common methods today are measuring with a total station, the GlobalNavigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently thedevelopment of unmanned aerial vehicles, known as drones, has increasedexponentially and today there are several ways of using drones for measuring surfacesby photographing and laser scanning.This thesis contains a comparison between the methods terrestrial laser scanning(TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements havebeen applied on two different test surfaces, one of asphalt and one of gravel. Thepurpose of the comparison is to investigate whether the airborne photogrammetry isequivalent accurate in its height levels as the terrestrial laser scanning. For thecomparison to be more extensive, these two methods have not only been comparedin precision but also in the areas of ease of use and economy.The precision was analyzed by comparing the height levels in randomly placed controlpoints on the test surfaces.

This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.
Värdeinverkan vid avsaknad av väg : Hur påverkas marknadsvärdet om väg fram till fastigheten saknas?
Syftet med studien är att ta fram ett grundläggande material för vidare undersökning avseende högre kvalitet vid taxeringsförfarandet i samband med justering av taxeringsvärden när väg fram till småhusfastigheter saknas. Detta då det idag inte finns några riktlinjer kring denna justering. Målet med studien är att undersöka vilken värdeinverkan avsaknad av väg till småhusfastigheter kan anses ha på marknadsvärdet, och vad som gör denna värdeinverkan svår- eller lättbedömd.Metoderna som tillämpats i studien avser en kvantitativ- samt kvalitativ undersökning. Den kvantitativa undersökningen har genomförts i form av telefonintervjuer med mäklare och fastighetsvärderare. Detta för att få en generell bild av hur marknaden anses uppfatta förhållandet avsaknad av väg.
En färdig trädgård : enkätundersökning om gruppbebyggda småhusträdgårdar
The main purpose with this master's thesis was to develop a survey with the intention to examine what expectations the JM AB:s customer had on a future garden and also to discuss if the lawn has a symbolic meaning in gardens.
The lion's share of the thesis is based on a survey, aimed at people in the company's customer database. The intention was to examine what expectations they had on their future garden and if their expectations were met when they later bought a house from the company. The work also consists of interviews and visits to areas with newly built homes.
I interpreted the result from my surveys as the lawn on its own being is a strong symbol for a garden and also signals a social status of the owner. To the company the pre made lawn on a role is a way of saving time and easily achieve what the customer request.
The company wants to create a concept of a "preset-garden" that meets the company's vision as well as the expectations of the customer.

Beräkning av ASME-flänsar enligt EN-standard
In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.
Telematik - en del i NBF? :
Samhällsutvecklingen går från industrisamhälle till informationssamhälle och Försvarsmakten (FM) går fråninvasionsförsvar till insatsförsvar. Tidigare var det mer regel än undantag att civil teknologi hade sitt ursprung imilitär teknologi, t.ex. Internet. Idag är det precis tvärtom med marknadskrafterna som driver utvecklingen avt.ex. IT i ett högt tempo.
De bortglömda stenarna : om byars äldre gränsmarkeringar och rågångar i Ekeberga socken
This essay is about the hamlets´ older boundaries, i.e. boundary lines (?rågångar?) and boundary markers in the form of rocks, and an own survey of two hamlet boundaries in southeast Sweden. Many of the boundary rocks were subjected to unintentional damage or destruction that arose during forestry activities, the excavation of ditches, or road construction. Boundaries between hamlets sparsely populated areas were not clearly defined from the beginning, but were established initially in the form of boundary zones, that often consisted of wetlands, watercourses, or mountain heights.
