A method for equine intra oral radiology has been tested. In the study, both a digital system with an intraoral sensor connected to a laptop and a system utilizing image plates and digital developing was tested, initially on cadaver sculls and finally on sedated horses. The digital sensor was not considered viable for this purpose, while the system with image plates and digital developing worked very well. Two different techniques, i.e. parallel and bisectris, are suggested for the best visualization of different parts of the teeth. Intra carious injections of Mixobar oesophaghus contrast fluid was found useful when evaluating the extent of carious lesions. Compared to extra oral radiology, the new method had several advantages and can be used both in clinic and field practices..

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Arbetet är utfört på uppdrag av Electrum Automation AB som med hjälp av prototypen vill utvärdera om en skarp produkt kan tas fram genom att använda billiga sensorer främst avsedda för konsumentbruk. AOS ska kunna användas för att mäta absolut orientering, dvs. lutning och riktning i förhållande till jordens gravitation och magnetfält. Den ska kunna appliceras i tuffa och säkerhetskritiska miljöer, t.ex.

Geodata finns idag tillgängligt via geodataportaler runt om i världen. På dessa geodataportaler beskrivs datamängder och tjänster som kommer från olika myndigheter. Geodatasamverkan har uttryckt intresse för att kunna beskriva realtidsresurser på dessa portaler med hjälp av metadata. Utifrån ett samarbete mellan SMHI och Lantmäteriet har denna studie tagits fram där en dynamisk realtidsresurs från SMHI testas beskrivas med Geodataportalens nuvarande struktur. Befintlig litteratur har undersökts för att presentera en bakgrund.

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

The purpose of this thesis was to investigate different methods do measure velocity of pistons in pneumatic cylinders at Bosch Rexroth Teknik AB. Through information of velocity the adjustment of a cylinders damping can be done easier.A future transducer will be used by salesmen, service personnel and customers. This requires a sensor that is easy to apply and use. It is also desirable that the sensor is cheap. A number of possible methods to measure velocity have been presented.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.

Title: Strategies for competition ? a study of the Swedish contact lenses market.Authors: Pernilla AArskog and Annika Lange.Background: As a market gets more mature and the competition increases, it is more important for a company to apply the right strategic perspective. There are four fundamental strategic perspectives for a service-oriented business: a core product-, a price-, an image- and a service perspective. This study is a about service management and take its point from the theories from the Nordic School about strategies for competition, customer value, perceived customer quality and customer loyalty.Purpose: The main purpose with this study is to analyze and evaluate how the actors at the Swedish market of contact lenses should compete to gain further competitive advantages.Method: The study includes four qualitative interviews with two traditional opticians and two Internet based businesses, but also a survey with 106 contact lens users is included.Analysis: In the analyse part of this thesis it was concluded that the traditional opticians conception about their customer not agrees with what the customer evaluate as important. Many of the customers have thought about changing their optician, and besides that do not recommend their optician, and can there for not be categorize as loyal customers.

Detta examensarbete har utförts på uppdrag av HEAB stängsel. HEAB stängsel säljer och monterar stängsellösningar till företag, fastighetsbolag och kommunala förvaltningar. Projektets syfte var att utveckla ett barnsäkert lås som kan användas till grindar vid förskolor. Låset skulle vara lätt för vuxna att öppna samtidigt som det på ett effektivt sätt skulle hindra barnen från att öppna grinden och gå ut. De lås som HEAB stängsel i dagsläget säljer har både ergonomiska brister och säkerhetsbrister.

Rörelseanalys är ett nödvändigt verktyg då det gäller bedömning, uppföljning och diagnos vid alla de sjukdomar som påverkar den mänskliga rörelseapparaten. Idag finns det i Sverige ett fåtal kliniska gånglaboratorier dit patienter kan remitteras för att få en mer detaljerad och objektiv bedömning av deras rörelsemönster. Problemen med dessa gånglaboratorier är att de är förhållandevis dyra och resurskrävande.Avdelningen för Medicinsk Teknik- FoU vid Norrlands Universitetssjukhus har därför initierat ett forskningsprojekt där AnyMo, ett mobilt system för mätningar av rörelsemönster, har utvecklats.Målet med detta examensarbete var att vidareutveckla det befintliga systemet till att simultant kunna mäta hjärtats EKG, då det skulle göra undersökningen mer komplett.De delar som konstruerades i projektet var en EKG-sensor och en Master Unit, som kopplades ihop med en befintlig rörelsesensor (del av AnyMo-systemet). Informationen från sensorerna lagrades lokalt i ett minneskort på systemets Master Unit.Den färdiga produkten testades och utvärderades på en motionscykel vid olika nivåer av fysisk ansträngning och varierande rörelsefrekvens..

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Både militärt och civilt finns det behov av att kostnadseffektivt kunna övervaka stora områden utan patrullerande vaktpersonal. Den sensor som beskrivs i detta examensarbete är tänkt att utgöra ett robust alternativ till traditionella övervakningssystem eftersom tekniken är billig och kan täcka in stora avstånd.FOI(Totalförsvarets Forskningsinstitut) utvecklar tekniken för sensorn på uppdrag av FMV(Försvarets Materielverk). Ett tidigare examensarbete [1] har utrett en enklare sensor och formulerat teorin för den sensor som den här rapporten behandlar. Sensorn bygger på polarisation och det faktum att en monomodfiber påverkar polarisationen olika beroende på yttre mekaniska påfrestningar. Med hjälp av flera testsignaler med olika polarisation kan tillräckligt mycket information insamlas för att fullständigt beskriva fiberns påverkan på polarisationen.

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.
