Automatisk trimning av en flexibel manipulator

Dagens industrirobotar är mycket mer komplexa än vad de var för några år sedan. Regleringen baseras på matematiska modeller och för att prestandan ska var lika bra eller bättre än förr krävs det att modellerna är anpassade till individen. Det krävs därför att modellparametrarna justeras för att stämma överens med den aktuella roboten.Rapporten handlar om hur de flexibla modellparametrarna ska trimmas för robotens leder så att verktygets svängningar minskar. På grund av att en rörelse på en axel påverkar de övriga axlarna, blir detta ett sexdimensionellt minimeringsproblem. Detta kan dock lösas genom att låsa vissa leder i olika positioner och på så sätt delas minimeringen upp i flera steg med som mest tre variabler att minimera över.

Stress, kontroll och socialt stöd inom Räddningstjänsten

Syftet med denna studie var att undersöka vad stress innebär, hur det upplevs och orsakas inom Räddningstjänsten, samt hur det kan förebyggas. Enkäten gjordes utifrån ett kvantitativt perspektiv och skickades till larmoperatörer och brandmän på Räddningstjänsten. Enkäten besvarades av totalt 33 respondenter. Deltagarnas ålder togs inte i beaktning, enbart antalet år av yrkeserfarenhet. Datan analyserades I SPSS, med hjälp av ett Chi-tvåtest och ett Pearsons's r-test.

Den trådlösa massan - svärmbeteende och kollektiv handling

This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

American Psycho ? En analys av Patrick Bateman som berättare

In order to be a good teacher according to preferences from outside the school area, there are many different voices to listen to. The different roles that are assigned for teachers are colliding with the latest research from the pedagogical institutions and therefore the role as a teacher of today is in a complex state of mind. Somewhere, between the traditional role of teaching and the moderating ideal image, reality is revealed in the ambivalent role of the teacher of today. In this pedagogical essay on advanced level we are focusing on obstacles that are hindering the moderating teacher?s role, to be fully developed in the classroom.

En man bland många kvinnor  : en studie om varför män väljer läraryrket i den tidiga grundskolan

 The english name of this essay is ?One man among many women?. This essay takes its starting point in the situation today with few male teachers in the earlier years of elementary school. I have decided to look at the small group of males that actually started the education to become teachers and why they did it when the profession as teacher today is low-paid, low status and is a profession with a large dominance of female teachers. I have chosen to write about this because of the importance for the children to meet both men and women as teachers in the early schoolyears.

Hydroakustisk kommunikation med bandspridningsteknik

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

Ekonomistyrningens påverkan på MRP-implementering: en fallstudie av ASSA AB

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

Tonala skillnader mellan en traditionell och en modern gitarrkonstruktion : En jämförelse mellan två klassiska gitarrer

During my studies to become a guitar builder at Carl Malmsten CTD, I have found an interest in the construction of the classical guitar. I am fascinated by the simplicity of its construction. A simplicity that becomes more complex when you start to study it in detail.In my final thesis I will not try to explain this complexity. The subject is to investigate two different principles regarding its construction. I would like to find out if the sayings concerning one of the principles will yield a guitar with greater ability to produce volume and projection.At a close distance the difference between the guitar?s volumes is not to speak of, but a significant difference can be seen regarding one of the guitars ability to project its sound.

Self-efficacy, arbetsprestation och arbetstillfredsställelse på ett callcenter företag i södra Sverige

This essay looks into the concept of self-efficacy and its implications for work performance. The participants in this study work for a call center company situated in the southern part of Sweden. The hypothesis is that a high degree of self-efficacy exerts a positive effect on work performance. Furthermore, the study seeks to identify the factors that give rise to work satisfaction among the participants. The results of the study show that there is a negative correlation between high self-efficacy and work performance.

Förändring och Mening : En studie om copingprocessen och utmattningssyndrom  bland präster i Svenska Kyrkan

Burn out is common among people who work with other people and occurs in both ecclesiastical and non ecclesiastical context. In recent years, the phenomenon has attracted increasing attention in the Church of Sweden and among persons who hold a consecration service as priests.The purpose of this essay is to study the text material from the two authors (Lennart Belfrage 2009 and Martin Petré 2013) and to analyze and describe them. Another goal is to see how the coping theory may be helpful for this group of priests to handle the situation arising in the time of burnout.I have used the qualitative research and hermeneutics method for categorize and encode the material in order to interpret and understand the underlying causes that could explain burnout among priests in the Church of SwedenPargaments (1997) coping theory has been important for analysis and explanation of burnout among a group of priests in the Church of Sweden.In the result, I have found four components that may be useful in the understanding of the cause of burnout. The analysis shows that Pargaments (1997) coping theory is useful to manage complex situations for example burnout, among priests in the Church of Sweden..

Dolt i det öppna

Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

Lek hos Stinkpadda (Bufo callamita): jämförelse av restaurerade och ickerestaurerade hällkar

The natterjack toad (Bufo calamita) is one of three species of toads living in Sweden. During the last decades declines in population numbers have been detected and are thought to be primarily due to loss of habitat, overgrown breeding ponds and competition from common toad (Bufo bufo) and common frog (Rana temporaria). In 2012 20 ponds in the location of Glommeskallen in Smögen were restored by clearing the ponds from overgrowth. The aim of this study was to investigate if natterjack toads used the restored ponds and if the restoration had made an impact on the natterjack population on the location. Presence of common toad and common frog was recorded, as was the presence of eggs and larvae of any of the three species.

Diplomati med klyvbar kärna - en kvalitativ studie av den ryska diplomatins grundval

AbstractThe purpose of this thesis is to analyse the basis of Russian diplomacy, and by doing that develop the analytical instruments available, in order to improve the comprehension between the parties in negotiations. Descriptions of the national characteristics of Soviet and Russian diplomacy are made by an analysis of memoairs and other examinations of their negotiating behaviour. To ensure the result of the characteristics two case studies of the non-nuclear proliferation negotiations are made, followed by a comparation between the Soviet and Russian diplomacy. From these results, I analyse the groundworks of russian diplomacy, using three theories about how ideology, national identity and prevailing self-image can affect the national negotiating behaviour. The results show that there have been changes in only some parts of the negotiating behaviour and that there is a need for all three theories to explain different parts of the complex system of Russian diplomacy which is based on the plurality of culture, ideology, language, ideology and history..
