Utveckling av OBD-II-gränssnitt för fjärrdiagnostik av fordon

This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.

Teknologier för fordonsdiagnostik

The capacity to extract information from vehicles has the potential to be very beneficial. Performing analysis on information about fuel usage, emission values and other driving properties of a vehicle can lead to great economic and environmental benefits.This report contains descriptions of two prominent systems for retrieving information of this nature from a vehicle, On-Board Diagnostics and FMS-Standard, and of an implementation of FMS-Standard.The conclusion drawn after this investigation is that these systems do indeed offer access to the benefits mentioned earlier, although to varying degrees and with differing prioritisation..

Aspergers syndrom : En enkätundersökning om åsikter rörande att Aspergers syndrom försvinner som egen diagnos och införlivas i autismspektrumtillstånd.

AbstractIn 2013, the diagnosis of Asperger?s syndrome will be eliminated as a stand-alone diagnosis, to be subsumed into the existing diagnosis of Autism Spectrum Disorder. In this paper, a study with the objective of emphasizing current opinions regarding the change in diagnosis is performed. Another objective is to examine the connection between identity and diagnosis. The study therefore targets people with a diagnosis, in this case Asperger?s syndrome.The empirical material of the study has been collected through a quantitative web-based survey.

Skattning av fordonsmassa med driftstatistik

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Fordonsgas från deponier : en potentialstudie i Biogas Öst-regionen

The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.

Att kunna rita en perfekt cirkel är super : En jämförande studie om hur lärare använder smartboards i undervisningen

The purpose of the study is to examine how the teachers in second grade use SMART Board and compare two schools.The process I used was qualitative interviews and classrooms observations. Previous studies shows how widely SMART Board is used in classrooms, and this has also been shown in my study. The study shows how differently SMART Board is used in the classrooms, and how important education in the technology of SMART Board is to achieve in the classroom. The final discussion clearly shows similarities and differences in the use of SMART Board in different classrooms and also the teachers? thoughts about SMART Board as a tool.A central aspect in the use of SMART Board shows how important the basic education in SMART Board is.

Att skapa allianser och förståelse. En studie om olika professioners arbete med tonåringar som har ADHD.

The aim of this study was to investigate how various professions within the treatment of ADHD is working with the diagnosis and the importance of the diagnosis has been at work. We also want to investigate what the different professions think of the diagnosis, what it has for opportunities or limitations in treatment. The chosen professions are two nurses, two treatment assistants, a psychologist and a psychotherapist. When we interviewed our chosen professions, we have used a qualitative approach with semistructured interviews. Through our interviews we got the opportunity to take part in the various professions' knowledge and experience of working with teenagers who have ADHD.

Att leva med en diagnos : Utifrån föräldrars berättelser

The purpose of our study was to identify and present experiences encountered by parents with a child with diagnosis. Those narratives are made open for the public. Data has been collected through ten interviews with parents having children with a diagnosis. These interviews have also been complemented by interviews with one child and one youth. The parents and the children who have been interviewed, all have their own stories and experiences of how it is to live with a diagnosis in the family and for all families there are different diagnosis.

Autonom bil med enkapseldator och ultraljudssensorer : tillämpning av en Arduino mikrokontrollerplattform och HC-SR04 sensorer

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

Utveckling av I/O-modul för trafikskyltsystem

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

Styrelsearbete över tid - En studie av företagsutvecklingens påverkan på styrelsearbetet i ett onoterat svenskt familjeföretag

In this study we have focused on how board work is affected by companies growth and development. This research has been conducted through a case study of Teleopti AB, a private Swedish family-owned company, together with theory and literature studies. We have studied the development of Teleopti since its founding in 1992 until today and what impact this company's development has had on Teleopti's board work and composition during the same period. Through the study we came to the conclusion that Teleopti's board work has gone from being supportive and advisory to more professional with a higher degree of board involvement. This change has been caused by the reduced information asymmetries, the increased need for board's expertise, the new board dynamics and the CEO change caused by the company's growth..

Styrelseproffs - Finns de?

During the past two decades a new expression has emerged in Swedish business linguistics: Styrelseproffs (appr. Board Professional). The aim of this paper is to study whether a board member legitimately can be considered a professional. This is investigated through the eyes of the theoretical framework of professionalization. The empirical data is collected through interviews and presents the perspective of people considered to be Board Professionals.

ADHD- diagnosen i skolan : En kvalitativ undersökning om fem pedagogers förhållningssätt till diagnosen ADHD i Åk 6-9

ADHD (attention deficit hyperactivity disorder) is a phenomena that is much talked about in both schools and in communities. Today, there is a conflict surrounding the diagnosis ADHD. A part of the conflict takes part between the sociologist Eva Kärfve and Christopher Gillberg, professor in child- and teenage psychology. The roots of this conflict surrounds the much debated line of what is seen as normal and ?too? different, basically how many children that actually should have the diagnosis.

Länsstyrelsen i Uppsala län : En arkivhandledning

The County Administrative Board is an authority with big variations in their work. The fact that the County Administrative Board work with so many different issues makes it difficult for the general public to get an insight in what they do and what kind of archival material they create. This handbook is made to illustrate what the County Administrative Board do and how you can find your way to the archives and its documents, both as an employ and as a public visitor.The Handbook begins with a historical overview of the County Administrative Board, from the 17th century to today, with focus on the County Administrative Board of Uppsala. As the Handbook is made for both employees and for the general public several ways to enter the archives are described.Since the employees at the County Administrative Board of Uppsala have access to the archives them self the Handbook also provides detailed descriptions about how to find the way to the records. These descriptions both explains the way to archives organized in dossier and archives organized in chronological order, both provided at County Administrative Board of Uppsala.All the records that the County Administrative Board of Uppsala has generated though the years are not available in the building of the County Administrative Board but at The National Archive in Uppsala.
