This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.

The object of this master thesis is to question why the sheet music heldby libraries is not used more than it is. I have mainly studied the inc idenceof any cooperation between the music schools and libraries,whether there has been consultation on the purchase of sheet musicand whether the music schools borrowed sheet music from the libraries.For the thesis qualitative methods were used in the form of interviewswith ten leaders in music or cultural schools in Sweden. The mainstudy has been focused on the library and music school in Vänersborg.To compare my results and draw conclusions I have used the work ofSanna Taljas: Music, Culture and the Library: an analysis of Discourses.The result of the study showed that there is very little cooperation betweenthe library section for music and the music school. The greatestinterest for cooperation appears to come from the library personnel.Both the library and the music school personnel claim insufficient timeand money for their lack of cooperation..

The purpose of this Master?s thesis is to examine what role the new city library in Halmstad has for its users. The questions posed in this study are: What do the users actually do at the library? What roles are the most significant according to the users? Have the politicians succeeded in their intention of realizing a modern library according to the users? The theoretical starting point is Andersson?s and Skot-Hansen?s theory of four different roles of public libraries. In order to extend the model we added a fifth function; the one of aesthetical experience.

SCA Skog has taken the initiative to this Master?s thesis. Today SCA Skog has a great need to update their informtion on young forest stands across large areas. Traditional field inventory methods for updating stand databases are expensive and time consuming. However, the inventory could be made more efficient if stand boundaries and stand characteristics are derived from aerial photographs.

The purpose with this master´s thesis is to examine how helth and unhelthy in the Swedish magazines Topphälsa, Fitnez Magazine, hälsa and I Form. The study is made from a discourse analytical approach and text and pictures are analysed together. The governmentality-perspective is also used as a theoretical frame. Power and govern are two inportant conceptions for this paper. Some of the main characteristics of the material are the double messages, the division in the categories "we" and "them" and the personal address to the reader.

This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.

This Master?s thesis presents a descriptive study of the intellectual process to describe images in such a way that they can be incorporated into written information systems. The purpose of the thesis is to concentrate on the scientific development for the last two decades, in the area concerning the description of images so that they can be organized and incorporated into information systems and possible to retrieve when searched for. Library and information science (LIS) has a strong tradition of turning to the iconographical theories of Erwin Panofsky and to semiotics according to Roland Barthes, for models and theories for the interpretation of images. The question for this thesis is whether LIS in this scientific field, has deviated from these models and theories, or are Panofsky and Barthes and their scientific work still providing for intellectual and practical guidance for LIS within this area..

This is a master thesis about the reconstruction of Bibliotheca Alexandrina. With a hermeutical approach utilizing literature review and interviews it examines how the library have come into existence, and what the Swedish efforts have been to help the project along. Using a mainly structural perspective, the major factors examined are world politics, Egyptian society and library values. The conclusion is that myths about the ancient library of Alexandria, the city of Alexandria itself, world politics, a more stable Egyptian society, improved world and Egyptian economy, an improved Egyptian reverence for reading and writing, less censorship, more freedom of speech and Egyptian national pride all have contributed to new library. Swedish efforts by Sida, the Swedish Institute in Alexandria, FAV and SWEBA have mainly been in the areas of information technology, education of Egyptian library staff and childrens literature..

Detta examensarbete gick ut på att enligt utvecklingsprocessen på Motion Control utveckla en prototyp av en kabelersättare för en produkt på företaget; USB I/O. USB I/O är en mät- och styrenhet och datainsamlingsenhet för USB-porten med flera in- och utkanaler som i flera applikationer har som nackdel att den är kabelbunden. Tanken var att göra en enhet som man ansluter USB I/O till och som kan kommunicera direkt med konventionella ?Bluetooth-dongles? som är vanligt förekommande på konsumentmarknaden.Tre undersökningar gjordes. Den första var en marknadsundersökning för att se lämpliga systemkoncept samt vilka konkurrenter som kan finnas.

The aim of this master thesis was to measure the terminological consistency when indexing fiction. The study included ten participants, five librarians and five patrons who indexed two novels in three steps. Besides calculating the terminological consistency a typified index based on the term frequency was created.Subject heading list Att indexera skönlitteratur was used as a controlled vocabulary and to calculate the consistency the asymmetrical formula was used.The result showed that the study produced relatively high consistency values compared to other studies. The subject heading list increased the consistency value for all of the participants, for the patrons the increase was substantial. The librarians produced higher consistency values compared to the patrons in almost every step and they had in percentage lower amount of terms used only once..

The purpose of this master thesis is to investigate if the mobile library has a similar role as the public library. To study this further we intend to examine the value and function of the mobile library. Answers are sought to the following questions: Can the mobile library be seen as a public library in a smaller scale? How do the users experience the value and function of the mobile library? What does the library staff think of the value and function of the mobile library for the users? What would the consequences be if the service of the mobile libraries would not exist? The method used was qualitative interviews. The groups of respondents are mobile library users and library staff.

The aim of this Master?s thesis is to examine the function of the budget as a means of control within an organisation in the public sector. To accomplish this, a case study has been conducted on a certain business unit within Luftfartsverket responsible for providing Air Traffic Control services. The thesis is built on a framework of contemporary theories of budgeting and includes a brief discussion of the weaknesses usually associated with the traditional budget. The conclusion of the study is that the use of budget as a means of financial control within Luftfartsverket is not efficient enough at the moment.
