I detta examensarbete har ett problem som varit en del av ett pågående projekt på ElektaInstrument AB undersökts och en lösning har föreslagits.Problemet har varit att utveckla och modellera en servoenhet som med hög precision kanpositionera ett instrument i fem dimensioner (tre translaterande och två roterande) och som kanhålla instrumentet på sin position med hög styvhet.Problemet löstes genom att först specificera kraven på servoenheten, sedan undersöktes olikabefintliga koncept för att uppnå kraven. Det bästa konceptet, en Stewart-Gough plattform, valdesoch studerades och analyserades sedan i detalj.Analysen gjordes i två steg, det första steget var att göra beräkningar av krafter och benlängdersom en funktion av positionen för en Stewart-Gough plattform. Det andra steget var att realiseraberäkningarna och implementera dessa i kod och hårdvara för att styra fysiska motorer och fådem att bete sig som önskat enligt beräkningarna.Resultatet av första delen av analysen är ett MATLAB program som kan beräknainverskinematiken och benkrafterna för en godtycklig Stewart-Gough plattform som belastasmed en godtycklig kraftvektor och en godtycklig momentvektor. Programmet kan även itereraberäkningarna för olika lägen för Stewart-Gough plattformen och för olika belastningar ochskriva ut extremvärdena som beräknats.Den andra delen av analysen resulterade i ett LabView program för simultan styrning av sexmotorer och hårdvara för att driva sex motorer. Styrningen har testats på befintliga motorer medlyckat resultat.Resultaten av examensarbetet visar att Stewart-Gough plattformen kan uppfylla kraven som ärställda på servoenheten.

Sweden?s tourism increases and new hotel opens. Since 1978 to 2011, the hotel rooms in Sweden doubled. International congresses, sports- and artistic events are a few examples of what affects the hotel industry. Sweden is seen as an attractive destination and future forecast looks to have a positive trend.

The purpose of this study is to investigate the tendencies among pupils concerning their attitudes towards History and some of the stated goals in the present and in the proposed course plan of History, since there is, probably, a change coming in 2011. The study is built on questionnaires answered by one hundred pupils at a Swedish upper-secondary-school. The results point to the fact that most of these pupils like history, but still they do not wish to make it an obligatory subject, which is a government proposal at the moment. Furthermore, the answers about sources, democracy, the use of History and the consciousness about History, have a clear tendency; there have been too little education about these areas during the pupils former nine years in school, still the pupils think that these are important areas to work with. Moreover, this study shows a disheartening picture when it comes to pupils knowledge of their cultural heritage. Only half of the pupils know which century Gustav Vasa lived in and just a third know what year universal suffrage was introduced in Sweden, two facts that ought to be set in most Swedes? mind..

ITT Flygt is a world leading company that mainly manufactures submersible pumps. A problem of ITT Flygt is that product development projects rarely manage to hold the estimated project time. It shows that something unexpected occurs in projects quite often, which results in delays. The delays can both be due to an optimistic time plan of projects and risks in product development projects which are not discovered at an early stage. This added with unforeseen delays makes it difficult for ITT Flygt to estimate the duration of their projects.The goal with the Master thesis is to examine a suitable method for simulation of project time.

This paper is about finding a set of unwritten rules pertaining to the teaching of history in an exclusively Swedish college. I want to know if truancy among immigrants has anything to do with SO teachers? choice of content or their teaching methods. Unwritten rules are a complex phenomenon but by applying different perspectives and teaching methods a pattern will emerge. It is possible to discover different influences in the way the teacher chooses their material and work plan.

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

My work has been to create a magazine for iPad to explore this format, whichthere are mixed feelings about. Instead of seeing the digital format as an enemy ofthe printed magazine, I have chosen to see it as an opportunity.I have given myself the task of designing a magazine that can justify the useof the digital magazine. I have looked at the identity of the magazine, but mainlyexplored the format and its prerequisites.I was triggered to do the project when I saw people who are just making a pdfof the printed magazine and publish it digitally. I have during my work discoveredhow near or far away you can be from the printed magazine.The format of the iPad has multiple aspects to look upon; one that turned outto be clear in my project was navigation. Working with a spread has its problemsand opportunities; the same applies to an article that is larger than a screen.

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

The purpose of this paper is to make an analysis of the urban Roman water system. I have chosen to work with the system as a general field, not as a case study of a single town. In my opinion such a study would not give a proper and fair view of the subject. Therefore, this paper will discuss the different parts of the system, each one for itself and name examples wherever possible, to give a wide survey of the reality of the Roman water supply system. The aim is to give the reader a clear picture of different solutions used in the time of the early Roman Empire and a good understanding of the subject..

The purpose of this thesis is to study the difference in value generation and its drivers between leveraged buyouts and listed companies. The primary objective is to observe if differences exist. A secondary objective is to understand the differences and attempt to provide an explanation based on earlier research on Private Equity. A selection of large Swedish LBO-transactions, carried out between 1998 and 2012, are analyzed and their value generation drivers subject to comparison with a weighted index of companies listed on the Nasdaq OMX Stockholm. A clear difference in value creation is observed, both in size and composition.

This report discusses how well the competences the master program in Information Technology, given by the Royal Institute of Technology, meet the demands from the business life. It is made qualitative and about 20 companies have taken part to get the results. The study has been made to see how well the three first years and the entire five year master, with different aiming, meets the demands. The results shows that the master program needs to be remodeled to meet the demands in the more ?softer competencies?, which for example is people management and an understanding about economical, juridical and cultural aspects.

Examensarbete har utförts på Atlas Copco Tools and Assembly system. Syftet var att utveckla ettkonstruktionshjälpmedel för att underlätta valet av elmotor och växellåda vid nyutveckling avautomatiserade skruvdragarsystem. Ofta görs valet av växellåda och elmotor individuellt vilketkan resultera i ett icke optimalt system. Genom att istället göra valen tillsammans kan ett bättreresultat uppnås.Syftet med examensarbetet var att ta fram ett Matlab- script som ger en bild över hur valet avväxellåda och motor påverkar varandra. Scriptet ska föreslå lämpliga dimensioner på motor ochväxellåda med hänsyn till hela systemet och dess uppgift.

ABB Capacitors Ludvika started their LEAN-project in november 2010, but still has not the whole factory been introduced to the LEAN-tool called 5S. 5S is only implemented on the ?easiest? work-areas.By implementing 5S, at the workingstation called inburkningen, would make the workstation and the area around it much more structured, clean and systematized. The operators are a little bit skeptical to the work that includes continuous improvement today, because they can not see any progresses. If 5S were implememted the operators would be able to avoid searching for tools because with 5S, each tool will have a specified place at the workstation.5S would simplify the cooperation between the shifts, because 5S includes clear instructions for how the workstations will be cleaned after each shift.This report will include my recommendations, thoughts and opinions regarding however ABB Capacitors Ludvika should implement or not implement the LEAN-tool 5S.

En olycka kan snabbt vara framme. För äldre personer kan ett fall vara tillräckligt för att skada sig rejält och inte ha möjlighet att komma åt ett kommunikationsmedel, till exempel en telefon. Detta är i dagens samhälle ett stort folkhälsoproblem som både orsakar lidande och stora kostnader. Infinner sig känslan av otrygghet kan det underlätta och framförallt hjälpa vid överfall att snabbt kunna tillkalla uppmärksamhet från omgivningen men också familjemedlemmar eller vänner.För att lösa dessa problem har ett säkerhetslarm utvecklats till en Android-telefon. Detta larm har i uppgift att påkalla omgivningens uppmärksamhet genom ljudsignaler men också kontakta anhöriga.
