Modellbygge av mekaniksystem och riktmotorer i stridsvagn 122
This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.
Automatisk detektering av akustiska resonansfrekvenser i trästockar
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Verksamhetsstyrning med fokus på intressenters och medarbetares betydelse : ett fundament för företagens varaktiga framgång?
We would like to gain a more in depth knowledge of whether the modern orientations both within corporate governance and control philosophy lay the foundation for enterprises? more sustainable success. These both modern orientations are increasingly focusing on the importance of enterprises? setting of goals and visions on the basis of stake holders? interests and the employees? more active engagement in and motivation for the goal achievement. Despite these common inherent characteristics, it is not evident from current scientific debate how such integration actually emerges in the control philosophies of the enterprises.

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.
IKT verktyg ? befrielse eller belastning? : Elever i behov av särskilt stöd och deras uppfattningar om IKT verktyg i lärandet.
The aim of this study was to describe and analyse the perceptions that ten 12-15 yearold pupils with special educational need, who had been assigned a personal computer, have about Information and Communication Technology (ICT) in the learning process. Data was collected by personal interviews and observations. Sociocultural perspective and phenomenographic research approach were used as theoretical and methodological frameworks in analyzing and understanding the result. The major conclusions were that most respondents perceived the computer as beneficial assistive technology for learning, but some felt singled out by having a computer to assist in learning. Students had various opportunities to succeed in using their tool depending on e.g.
Kalkylering av bearbetningskostnader
At a manufacturing company, due to the competition the price is reducedtowards the manufacturing cost. Therefore it is important to maintain control ofones costs and keep calculations up-to-date.This thesis deals with cost accounting at a aluminium-processing company. The report focuses on calculating machine cost per hour since the manufacturing costs are the major part of the total product cost.Managers on the company believe that the costs they use in calculations todayneither is up-to-date nor advantageous in a market aspect and due to that their calculations need to be revised. The machines cost per hour is a major part in the manufacturing calculation. The company wants to provide a competitive price that also covers their costs.
Pilotmodeller till flygmekanisk simulator för JAS 39 Gripen
AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.
Variationen i användandet av IT-verktyget Trade : En fallstudie hos NCC
Companies that are facing the global market are put in to new challenges in order to streamline its business. One industry that has realized that changes are necessary is the construction industry, it is an industry witch is far behind the development of introducing information technology-tools systems in there business. It has shown there is a relation between high IT usage and high productivity, which is one of the reasons to why companies in the construction industry should purchase a business system especially for procurement. However, companies that have purchased a business system are facing difficulties in having their employees using it for its purpose. People react differently to changes and that?s why variations in quantities exist for usage of information technology-tools.
Styrning mot förändring: En fallstudie rörande organisatorisk förändring i offentlig sektor
This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.
Den nya kassaregisterlagen
The government appointed in 2004 a special investigator with the objective to investigate the possibility of introducing a new law concerning implementation of obligatory cash registers with certain certification. This resulted in SOU 2005:35 ?Krav på kassaregister - Effektivare utredning av skattebrott? (Proposition 2006/07: 105). Following advice received from the respondents, the government has drafted a bill submitted to parliament in March 2007. Government bill 2006/07: 105 proposals for new law on cash registers, and submitted to parliament 2007th Act (2007:592) on the cash register was adopted by parliament in March that year and came into force on 1 January 2010.
Störningsindikation på lågspänningsnät
Föreliggande rapport är avsedd som ett examensarbete i elektroteknik (20p).Syftet med arbetet är att skapa en applikation för att finna störningar pålågspänningsnätet upp till 95kHz. Bakgrunden till arbetet kommer frånenergibolagen som vill kunna skicka datainformation direkt pålågspänningsnätet, detta vill de kunna göra med hastigheter mellan 2k ? 5kHz. Beroende på med vilken hastighet man vill skicka information kan störningar mellan givna frekvenser hindra datatransmissionen, därför är detviktigt att hitta vid vilka frekvenser störningarna uppstår så att lämpligaåtgärder kan vidtas.Grundläggande delar i applikationen är ett oscilloskop för mätning, dator medGPIB- kort för upptagning av data och LabView programvara för hantering avdata. För frekvensanalys kommer Fast Fourier Transform, FFT, att användas,varvid en grundläggande beskrivning kommer att medfölja..
Mångfaldens fiende Nr. 1 : En studie om 2010 års mediekoncentration och dess konsekvenser för samhället
Purpose: The essay was designed to examine what impact an increased media concentration in the provincial press may have on the society in the future. I also had the intention to create a greater understanding of the concept of media concentration and how the media groups relate to the public interest. Method: The work with this study was conducted by using methods from the qualitative methodological arsenal through interviews with, for the study, relevant informants, but also through a case report on the Stampen Group. The selection of informants had a background and a breadth which secured the credibility in this survey. The starting point was taken in previous research via a deductive approach where I tested how existing theories match reality. Conclusion: After completing this study should be noted that all respondents believe we will see a greater concentration of ownership in the Swedish media market in the future, and that it will reduce diversity. However, there are steps to take which I believe can work well in theory but perhaps not always in practice.
