ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
Belastningar i bettet och dess korrelation till hästens rörelsemönster vid körning på rakt spår :
The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse.
The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes.
From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits.

Mekaniserad spaning i dag och i framtiden
Den mekaniserade bataljonens främsta sensor att samla in underlag till underrättelsesektionen är spaningsplutonen. Spaningsplutonen på mekbataljon har bytt organisation över åren och gått från att vara ett terrängbils eller bandvagnsburet förband till sin nuvarande form med stridsfordon 90. Men har förbandet använts på rätt sätt sedan det tillfördes stridsfordon? Hur bör framtidens chefer nyttja plutonen för att maximera effekten?Arbetet baseras på de reglementen som finns idag samt intervjuer med personal tillhörande spaningsplutonerna och bataljonsstaber. Utöver det kommer en jämförelse med US Army Armored Cavalry göras..
Maternal behaviour in pigs and its relation to piglet performance and survival
Piglet survival is of importance because it affects the farmer?s economy and the welfare of the pigs. There are several factors affecting piglet survival and they are often linked to each other. This paper will focus on how the behaviour of the sow can affect the growth and survival of the piglets and also possible causations of differences in maternal behaviour. Sows in intensive production systems have different possibilities to express their maternal behaviour than free ranging sows.
Utveckling av reglersystem till quadrokopter
The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
Alternativa produktionsmetoder vid anläggningsarbeten Kringgjutning av el- och telekabelkanalisation
I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.
Malmmineralogisk undersökning av Pb-, Zn-, Cu- och Ag-förande kvartsgångar i Värmskogsområdet, mellersta Värmland
AbstractPolymetallic (Pb-Zn-Cu-Ag-Au-Sb-As-Bi-Cd-Te-Se-Ge?) quartz veins occur in an area from Eidsvoll in southeastern Norway to west of LakeVänern in southwestern Sweden. They most likely formed during the waning stage of the c. 1 Ga Sveconorwegian orogeny. In Värmskog parish, Värmland county, several mineralized quartz veins of different types are known.
Går det att mäta blodtryck med fotopletysmografi och bioakustisk sensor i kombination?
The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.
Syns du inte så finns du inte : en studie av kvinnlig representation i fyra svenska musikmedier
Det finns ytterst få beskrivningar av kvinnliga musiker och deras musicerande genom historien. I dag syns fler kvinnor på musikfältet, men männen dominerar fortfarande musikmedierna i stort, både vad gäller artister och journalister. Syftet med denna uppsats är att ta reda på hur ofta och hur mycket kvinnliga respektive manliga artister syns i musiktidningarna Sonic och Lira musikmagasin, i radioprogrammet Mitt i musiken och i tv-programmet PSL- på festival. Vidare vill jag undersöka hur många av texterna och inslagen som är gjorda av kvinnliga respektive manliga journalister. Med hjälp av dessa två representationsstudier undersöker jag sedan om det finns ett samband mellan artisternas kön och journalisternas kön.

Institutionaliserad symbolpolitik? En studie av skriftliga förklaringar i Europaparlamentet
Written declarations in the European Parliament have not been given muchattention in the field of political science. The scope of this Master's thesis is toexamine whether symbolic politics are present in written declarations and howthis may show. In this study, the aspects of symbolic politics of writtendeclarations of the sixth parliamentary term are examined using a taxonomy foridentifying symbolic politics developed by Peter Santesson-Wilson. Thetaxonomy is applied on 15 written declarations, all adopted by the EuropeanParliament, dealing with a variety of EU-related issues, ranging from July 2004 toJuly 2008.The main findings of the study show that symbolic politics is a presentphenomenon in nearly all written declarations (13 out of 15 cases) subject to thisstudy.In the final chapter of this study inter alia symbolic politics as a deliberateaction is discussed in the view of written declarations. Irrespective of this, onecould say that symbolic politics are institutionalised in the European Parliament,at least when it comes to written declarations..

Gränsen mot omgivningen : hur formas stadens kanter?
The edge or the fringe of the city is often the first part of the city we encounter, and our perception of it will probably color the image we make in our minds of the city as a whole. Even though the fringe of the city is important to the image of the cityscape it has not very often been the direct object of attention either in planning, building or even in the heads of the masters, when big ideas were formed. More often than not the fringe seems like something that just happened over time due to separate landowners, businesses or actions of other financially strong operators. The aim of this essay is to try to describe the history of the city edge in Sweden, from the very first town in the 10th century until today?s expanding mosaic of different ideas and styles as well as to bring some clarity and order into some of the different ideas and ideals in the planning of the edge in different eras and to review how the edge has been shaped and used.
Realtidsstyrning av IP-kamera
The final thesis named Tracking in Sensor Networks was created by the company Instrument control Sweden. The thesis work is to create a plug-in to an already developed software pro- gram, SkyView. Via the software program one should be able to control an IP-camera from AXIS, model 215 PTZ, with the appropriate protocol over a network. An Application Programming Interface, API, was used to easily control the camera through SkyView. The interface is called VAPIX and is used to all cameras from AXIS.
