Rapporten fokuserar på MY500 som är en jetprinter som skjuter lodpasta påkretskort utan att beröra den. Syftet med rapporten är att undersöka möjlighetenatt ersätta den nuvarande skruvpumpen med en spiralpump. Intentionenär att utarbeta en prototyp där spiralpumpen drivs av en positionsåterkoppladlikströmsmotor (DC motor). Prototypen används för att verifierafunktionen hos den tidigare oprövade spiralpumpen och för att fastställa om enstandard DC eller växelströmsmotor (AC motor) kan användas för att ersättaden befintliga stegmotorn.Arbetet börjar med en undersökning av olika motortyper för att sedanskapa en Matlab/Simulink modell med den valda motorn och parametrar förfriktion och tröghetsmoment. Genom simulering används modellen för att undersökaolika reglerstrategier vilka omfattar både hastighets- och positionsreglering.Olika samplingsfrekvenser analyseras för att hitta en lämplig regulator.Prototypen används för att verifiera regulatorns beteende och för att fårealistiska systemparametrar.

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

The aim of this study has been to examine if an implementation of a One Stop Shop in the public sector and its IT-support can serve as a motor for business development. By examine the relation between the One Stop Shop and the public administrations we have tried to answer this question. The municipality that we have examined underwent a big change, seven years ago, when they implemented a One Stop Shop including a IT-support called Flexite. But despite these seven years and the fact that Flexite has changed approach from a Case Management System to a Support System for Business Development the municipality have not adapted to this change. .

Introduktion: Sjögrens syndrom (Ss) är en kronisk reumatisk sjukdom som förstör de exokrina körtlarna i kroppen. Detta leder till minskad salivproduktion. Nio av tio av de drabbade är kvinnor i medelåldern. Sjukdomen finns som primär Ss och som sekundär Ss. I dagsläget finns inget botemedel mot sjukdomen därför riktar sig behandlingen mot att lindra symtomen.

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

The aim of this study is to investigate oral peer review on argumentative speech and to study the attitudes towards this peer review. The investigation was performed in an up-per secondary school class, and it focused on the different types of oral responses students give each other. In addition, the study investigated in what way the students experience this type of peer review. The results show that students reflect on form and performance as well as content, but they place more emphasis on form and performance than content. Students are positive about peer review and its importance for their progress.

Riskbedömning är en väsentlig del av klinikerns vardag. Varje patient ska riskbedömas och riskgrupperas, vilket sedan utgör grund för val av behandling, behandlare och revisionsintervall. I tandvården i Sverige idag används det ett flertal olika stödsystem eller riktlinjer för riskbedömning av oral hälsa. Syftet med studien var att ta reda på vilka stödsystem/riktlinjer som finns för riskbedömning av oral hälsa i Sverige idag och ge en beskrivning av de mest frekvent använda systemen samt göra en jämförelse av dessa. Syftet var också att undersöka huruvida dessa system är evidensbaserade och utvärderade samt att kartlägga kunskapsläget, gällande evidensbasering och utvärdering av stödsystem/riktlinjer, för riskbedömning av oral hälsa.

Seventy-two working horses (they had been ridden with bit and bridle within the last two weeks) were examined in the oral cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system. The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Syftet med studien var att sammanställa vetenskaplig litteratur angående patienternas livskvalitet samt sjuksköterskans omvårdnadsåtgärder med avseende på orala komplikationer som är ett vanligt förekommande problem hos patienter inom palliativ vård. Våra frågeställningar var: Hur påverkar orala komplikationer livskvalitet hos patienter inom palliativ vård? Vilka omvårdnadsåtgärder kan sjuksköterskan utföra dels för att patienter ska bibehålla god oral status och dels för att patienternas resurser stärks och balansen mellan dagliga livets krav och inre respektive yttre resurser upprätthålls? Metod: En litteraturstudie baserad på elva vetenskapliga artiklar. Som teoretisk referensram valdes Carnevalis balansmodell, Dagligt liv - Funktionellt hälsotillstånd. Resultatet visar att fysiska besvär och psykosocialt lidande till följd av orala komplikationer påverkade patienternas livskvalitet i stor utsträckning.

Syfte: Syftet med denna enkätstudie var att kartlägga hur dental implantatbehandling påverkar livskvaliteten avseende upplevd tuggförmåga, smak, talet, utseendet och munhygienvanor samt själförtroendet.Material och metod: En empirisk enkätstudie med kvantitativ ansats utfördes på tre olika tandkliniker i Stockholm under perioden feb - april 2012. Enkät med följebrev och frankerat svarskuvert sändes ut genom konsekutivt urval till 83 patienter. Fyrtio patienter varav 15 män och 25 kvinnor, med medelåldrar 66,5 år (34 ? 89 år), valde att delta i studien. Analys av svaren utfördes i statistikprogrammet IBM® SPSS® 19.Resultat: Andelen deltagare som upplevde en förbättring i upplevd tuggförmåga uppgick till 42,5 %, talet och smaken upplevdes inte ha förändrats av 85,0 % efter implantatbehandling.
