Utveckling av sensor för mätning av hjärtaktivitet

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..

USA som hård, mjuk och smart makt -En studie av amerikansk utrikespolitik i mellanöstern

This essay is built upon the thoughts of Joseph S. Nye concerning power, and the different ways of exercising that power. The characteristics of Nye's theories are the thoughts about the second face of power, or what he describes as the soft power. The essay seeks to examine what kind of power the US has been in their work for non-proliferation and democracy promotion in the Middle East. It also seeks to find what it is that makes the US to choose to exercise the specific powers.

Power supply monitoring for wireless sensor platforms

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.

Fiberoptisk kabelsensor för perimeterövervakning

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.

Bilder av Sverige i Italien

Title: Images of Sweden in ItalyNumber of pages: 5252 (589 including enclosures)Author: Oskar GustafssonTutor: Martin NilssonCourse: Political Science C level ? Bachelor?s ThesisPeriod: Spring term 2010University: School of Social SciencesLinnaeus UniversityPurpose/Aim: The purpose of my research study is to, through the use of political science theories on soft power and marketing theories about nation branding and in comparison to previous studies on the image of Sweden in Italy, gains a better understanding of the image of Sweden in Italy, with special focus on national political institutions and young Italians.Method: The method of analysis is a combination of qualitative methods: interviews where information about the image of Sweden amongst national political institutions were gathered and a survey where information was gathered about the image of Sweden amongst young Italians.Main results: On the basis of the results I have gained it can be concluded that a positive and well informed image of Sweden emerges when it comes to cultural and social factors but a more restricted and somewhat negative image come to light when asking national political institutions and young citizens in Italy about their views and knowledge on Swedish domestic and international politics and economics.Keywords: Soft power, Public Diplomacy, Nation Branding, Images of Sweden, Italy..

Har forskningen om internationella relationer någon praktisk betydelse? : En studie om idémakt i utrikespolitik

The aim of this paper is to get a deeper understanding if research about international relations has any practical meaning. The main focal point is about the importance of the scholar idea soft power, and its meaning on foreign policy actions through expressions. A quantity and quality method is used. The point of the main theory that concerns international relations takes a rationalistic perspective, and expands it to the notion that ides can have an impact on policy outcomes. Three different types of research utilization can be traced to determine in which way an idea is getting implemented.

Smarta Hus: Nya behov och lösningar med participativ design

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. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

Sensorer i brownout

När en helikopter befinner sig i brownout saknar besättningen referenser till omvärlden vilket kan försämra det spatiala medvetandet. Om besättningen inte har koll på helikopterns position i luftrummet kan det leda till skador på både materiel och besättning i samband med landning. Denna rapport undersökte, på ett övergripande plan, vilka möjligheter sensorer inom det elektromagnetiska spektret hade att bidra med information till det spatiala medvetandet. Rapporten fann att sensorerna behöver vara anpassningsbara till följd av stoftmolnets vida varierande karaktäristik. Sensorerna hade möjlighet att generera en bild av landningsplatsen före brownout inträffar.

Ultraljud av karpus på häst : en metodbeskrivning

Lameness from the carpus is not unusual in the horse. Multiple soft tissue structures such as tendons, ligaments, the joint capsule and synovial structures can be the originating source. All these structures can be examined with ultrasound, although a description of a systematic examination method is lacking. That is ? which structures, what they look like in an ultrasound examination, how to look at them in the best way, and in what order.

Musik som kommunikation

Music affects us humans. Marketing has long made use of music as a means to enable customers to identify with a brand, and thus increase sales. The Influence of music is obvious, but can you use this on students, and how effective is it to use in a classroom?I will answer the question: how does soft music provide reassurance/create a harmoniums learning environment at the beginning of a lesson?By observing how students react and behave to the playing of soft music. My aim is to create different strategies that teachers can effectively use to get students to ?jump in? to their lessons without wasting 5-15 minutes of class time.Professor Lennart Grosin conducts research into what is in Sweden called PESKO.

Positionering och kartuppbyggnad med avståndsmätande laser

This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.

Är medieelevens datorkunskaper likvärdiga medielärarens? : En självskattning från lärarens och elevens perspektiv

The aim of this essay is to get knowledge and to evaluate if the media student has equal or evenbetter knowledge of information technology (IT) than his/her teacher. Today the student of IToften has knowledge of hard ware and soft ware sometimes even unknown to the teacher. Themain reason for this might be that IT hitherto has played no prominent part at the institutes ofteacher education. Continuing further education of IT for teachers is also eligible as IT still is arather new subject on the time table.To adopt an empiric approach to the problem I have used trough interviewing and questions bothteachers and students at two upper secondary schools in the province of Värmland. The schoolsare called ?A? and ?B? in my investigation.Does the teacher have enough knowledge to give the student relevant knowledge concerninghard ware as well as soft ware to handle the computer and to utilize its possibilities? How can theteacher act to comply with the students? claims and demands?IT-knowledge can be expressed in a complicated way but I have limited my investigation to therole of the teacher and how he/she manages to teach and instruct concerning a selected numberof soft ware and how the students evaluate their own knowledge compared to that of the teacher.My investigation shows that the teachers consider their knowledge relevant for their task asinstructors and teachers.
