Trådlös kamerastyrning
As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

Drömjournalen : En studie av vårdmedarbetares upplevelser av samtida och framtida vårdkommunikation
The effectiveness of communication in the Swedish healthcare system context has long been the subject of debate. Issues stemming from usability, accessability and interpretation affect the lives of patients, and yet the vocal groups in the healthcare communication debate are patients and administrators, not healthcare professionals. With the advent of eHealth services and new demands being put forth on the ability of healthcare professionals' to handle increasingly numerous and innovative systems, it is of more importance than ever to understand the healthcare professionals' work context. This article is based on interviews with five healthcare professionals concerning their views on electronic health records (EHR), eHealth services, trends in healthcare services development in Sweden, as well as their views on the future of eHealth solutions and health information technology (HIT). Analysis of collected information shows an apprehension among healthcare professionals towards electronic communication, as well as a dissatisfaction with the usability of modern healthcare systems.
Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm
When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
Elektronisk motorstyrning för ottomotorer
The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
Läkares användning av medicinska tidskrifter ? Är sjukhusbibliotekets bestånd en viktig källa?
The purpose of this study is to find out how and to what extent doctors use the hospital library?s collection of print and electronic medical journals. Major changes have the last years occurred in the journal collection. The journals are very costly and little is known about the user satisfaction with them. Therefore it?s important to examine how satisfied the users are with the collection and how they utilize it.
Rotationsdämpare med integrerad fjäder
This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5.
Sjuksköterskors uppfattning av elektronisk dokumentation avseende tidsåtgång, teknik och vårdkvalitet
Documentation in electronic journals is perceived as time consuming and sometimes technically difficult to handle, but also leads to an improved quality of care. Objective: The purpose of this study was to investigate nurses' perceptions of documentation with a focus on timing, technique and quality of care and whether any differences in these perceptions were dependent on age. Method: Quantitative descriptive cross-sectional study in the survey form, 28 nurses at a university hospital in central Sweden participated in the study. Regression analysis was performed with Spearman's rank correlation coefficient. Results: Electronic documentation takes 30 to 60 minutes for most nurses and half of them considered it a reasonable time.
Mobilen den är alltid med: En användarundersökning av elektroniska mediers påverkan på ungdomars livsstil
The aim of this Master?s thesis is to examine how the lifestyle of youth between the ages of 15-17 is influenced by electronic media and also what view and opinions youth has regarding electronic media and lifestyle. We intend to examine how and when the youth use electronic media in their everyday lives, what purpose the electronic media has in the life of the youth, and finally what views and opinions regarding electronic media and questions regarding lifestyle the youth express. We as librarians and adults need more knowledge on how youth use electronic media and also what thoughts they have regarding media and lifestyle. We would like to bring some knowledge to the discussion in this area with our study to librarians as well as parents.
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.
Elektroniska böcker på bibliotek: Bibliotekariers och användares syn på elektroniska böcker utifrån intervjuer och samtal
The purpose of this paper is to describe how librarians andusers think of electronic books in libraries. My questions are:-What are electronic books, and how do they work?-How has electronic books been implemented by librariansin the libraries and on the libraries? websites?-How do users describe their view of electronic books?-How do the librarians and users think of electronic book inthe future?To be able to answer these questions I have studied relevantliterature, made qualitative interviews with two librarians attwo similar libraries and I had dialogues with several usersElectronic books were introduced 2002 at the two libraries.In the beginning the libraries made different types ofmarketing, but today they only have the website withinformation. Their purpose was to try this out and offer theusers a new media. So far, there are few users who borrowthese books, and maybe it depends on technical conditions.According to the dialogues I had, most of the users have noidea what electronic books are.

The municipal sector is characterized by its transparency and its responsibility for the taxpayer?s money. We therefore wonder which possibilities the municipal sector has to use reward systems as a men of control. Purpose: We intend to research the possibilities that the reward system offer as a mean of control for employees at the higher municipal level, with a special focus on commitment and motivation.
Ekonomistyrning i primärvården - En jämförelse mellan privata och offentliga utförare
The aim of this thesis is to analyze and explain the similarities and differences in management control between a private and a public primary care company. A comparative case study was developed based on one public and one private primary care company in Stockholm County Council. The framework of Otley (1999) was used to define and limit the area of management control systems, according to his five factors. For the analysis of the empirical results Hood's (1995) seven doctrines of New Public Management was applied, and customized to fit the purpose of the study. The results indicate that the differences between the two organizations are very limited.
Organiserad vetenskaplig elektronisk [publicering] vid universitet och högskolor i Sverige
Institutional repositories are now being created to manage, preserve, and maintain the digital assets and intellectual output of a university. The incentives to change the process of scholarly communication have also begun serving as a strong motivator. There are problems to consider and questions to be solved when dealing with electronic publishing and the implementation of institutional repositories. At present time no summary exists regarding the activities of scholarly electronic publishing at Swedish universities and university colleges.This Master's thesis aims to describe the current situation regarding electronic publishing and the development of institutional repositories at Swedish universities and university colleges. To investigate the situation, a questionnaire was sent out to 38 academic libraries since they are normally responsible for the electronic publishing within institutions of higher education.
