Thomas Kuhn och paradigmteorin idag : Från normal till postnormal vetenskap

This essay describes the philosophy of science that Thomas Kuhn puts forth in his work The Structure of Scientific Revolutions. The question is, does his description of the scientific paradigm work as well today as in the examples he gave in the book?The conclusion is that there are certain factors that make for a number of differences between science today and, for example in the seventeenth century. There is also a growing theory or vision of a post normal science laid developed by among others Jerome Ravetz. This theory or vision is an idea of a science close to peer-communities and fast as well as critical decisions involving opposite values..

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Information ochmaterialflödesförbättrings analys

This examination work is performed at the institution of industrial economy and production at Jonkoping technical university, for JELD-WEN Door Solutions plant in Forserum.Today the focus in the company is on to reduce their inventories binding of capitals as well as inventory of products and that includes to get a good control of the supply and handling of material which is of great importance.JELD-WEN Door Solutions is one of the worlds leading producers of windows and doors and the head-office is located in Oregon, USA.A great number of wooden doors are manufactured by the company in varying of constructions, classifications and performance.The production of the plant in Forserum has a project- and customer focus manufacturing where only internal doors are produced.

Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Organisationskultur samt avvikelse- och förslagshantering för ständiga förbättringar i tjänsteverksamheter : Fallstudie Vägverket

Because of an increasing demand from customers and changing external environment, there is a need for continuous improvements, for both manufacturing and service organizations, to meet these demands. Manufacturing organizations have been working systematically with quality improvements for a long time, but it has not been as common for service organizations. Because of that the methods to use for implementation of the systematic improvements have not been designed to fit service organizations, and not either for public organizations. The purpose of this thesis is to explain if and why the Swedish Road Administration?s organizational culture and handling of ideas and deviation support an implementation of continuous improvement management.

Androidvetenskapen och den kusliga dalen: Japanska robotar som forskningsplattformar och filosofiska leksaker

The primary aim of this essay is to analyse, contextualise and problematise the scientific and technological goals of android science. The starting point of this investigation is the history of automata and man?s attempts to recreate himself by technological means. Drawing on the no-tion of boundary work this essay also analyses the efforts of the proponents of android science to establish and demarcate a new interdisciplinary field. A secondary aim of the essay is to evaluate the scientific support for the uncanny valley hypothesis and to investigate how this hypothesis contributes to android science.

Emballage för väggelement i trä : Paketering, hantering, lager och transport

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

En rörig historia : en fallstudie över Secorocs processflöde av DTH-rör

Abstract Title: A messy story ? a case study of Secorocs process flow of DTH-pipes Presentation date: 2010-06-02 Course: Bachelor thesis in businessAuthor: Kristoffer ForsmanAdvisor: Kjell GustafssonKeywords: Management control, process control, lean production, process flow analysisPurpose: The purpose of this bachelor thesis is to develop an overview of the process flow for a specific product, and with the help of this mapping based on a lean production philosophy show possible improvement proposals and how these can lead to a more efficient process flow.Methodology: I have used a case study of Secorocs DTH-pipes and my primary data are gathered through interviews and observations. I have used theoretical framework to establish a process flow analysis. This is to obtain data on process activities and whether they are creating value or not. This leads to a current mapping of the situation in Secoroc on DTH-pipes and then analyzed and suggestions for improvement are developed.Conclusions: That by using the above mentioned mapping of process flow of DTH-pipes, problem areas could be illustrated.

Processer för Systems Development : Kartläggning, problemanalys och ? prioritering

This master thesis was performed at Scania Research & Development. The given mission was to see where the department Systems Development should focus to improve their development work. Thus the purpose was to map the product development processes in which the department works today and within them identify improvements. To fulfil the purpose a theoretical study of relevant terms, such as improvement work, product development and processes, initially was formed. The mapping method used is called "walk trough" and meant to let the people working in the processes be guides in their own process.

En studie av en misslyckad implementering av förbättringsmetodiken Six Sigma: Tre avgörande faktorer

The improvement programme Six Sigma has often been surrounded by an air of success since it was introduced in the 1980s. Yet there are cases in which introduction of the Six Sigma improvement programme show far from successful results, even complete implementation failures with no traces of the Six Sigma methodology or any improvements after completion of the introduction. These failures can cause severe damage to organizations through direct monetary loss caused by a negative result of the investment. Indirectly the failure can cause confusion in the organization and loss of employee motivation. The conclusions have been derived based on a qualitative case study at a Swedish telecommunications company.

Naturvetenskap i förskolan : En intervjustudie om förskollärares tankar och arbetssätt

The aim of this study was to investigate how preschool teachers think about preschoolscience, what they consider science to be and how they deal with specific curricular objectivesrelated to science.Science is a part of our everyday life, it is a prerequisite for understanding everydayphenomena and how the world is working. Nevertheless it is often dropped in favour of othersubjects in Swedish preschools.The eight preschool teachers participating in this study are all working in the samemunicipality in the western part of Sweden with children aged 1- 5 years. The method used inthis study was interviews. The interviews were recorded to facilitate the transcriptions.The results show that preschool teachers find that science is an important subject that shouldbe introduced to the children early on in life. They also show that preschool teachers considerscience to have a preventive effect on the learning to the children, and it is needed for them tounderstand everyday processes and phenomena.
