In this master's thesis the problem of determining the uncertainty for an estimator of an unknown parameter is considered. The case we study is the estimation of gravity using a reversible pendulum. This involves the estimation of the point where two regression lines intersect. The estimated gravity is a function the coordinates of this point. One way to determine the uncertainty of this estimator is to use bootstrap methods.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

C-uppsats som avhandlar de centrala begreppen i Guidelines for Operational Planning(GOP) (Centre of Gravity, Decisive Points, Direct and Indirect Approach, Culmination,Manoeuvre, Temp, Operational pause och Lines of operation) granskat i ett historisktperspektiv.Uppsatsen försöker verifiera hypotesen att Guidelines for operational planning (GOP)centrala begrepp fungerar och är applicerbara på alla operationer. Ett belägg för detta är attman kan identifiera begreppen i en historisk operation.Tyska väpnade styrkor från Wehrmacht, Kriegsmarine och Luftwaffe genomförde ett anfallöver havet och i luften mot Norge den 9 april 1940. Operationen var av tyskarna döpt tilloperation Weserübung-nord och var mycket vågad. I uppsatsen kommer denna operation attvara det historiska perspektivet.

Syftet med denna litteraturstudie var att beskriva vilka omvårdnadsåtgärder som kunde minska oro hos patienter som ska genomgå kirurgi. I studien ingick 15 stycken artiklar som belyste omvårdnadsåtgärder för att minska patientens oro. Analysen gjordes med en manifest innehållsanalys.

In recent years, agile software development methods have become increasingly popular throughout the world. Today there are a number of different agile methods and they all rest on the Agile Manifesto that was formulated in 2001 as a reaction to the traditional software processes.The aim of this thesis is to make a survey of some of the agile methods used today and to see how they are being used in practice. It consists of two parts: a literature study and an interview study with people working in the software business. First, a definition of agile methods is proposed and a number of different agile methods are described. Second, the interviews are being analysed with special focus on communication, collaboration, expectations and results.

In this study the author will search on how, co-operation between teachers and guidance counse-lors in school works. The study was too looking for if guidance counselors experiencing if they can feel cooperation in school, when they work by themselves in their profession, and if the guidance counselors feel a part of the whole school.Total interviewed four guidance counselors in elementary school, in a medium sized town somewhere in Sweden. The author have used qualitative methods for allow guidance counselors to answer free and not influence from other parametric.The result demonstrates that all guidance counselors believe that it is important to have coopera-tion with teachers in schools. Most of the guidance counselors believe that neither the directors nor teachers really know what skills guidance counselors possess. The respondents describe that they often turns to teachers who believe that guidance is an important part of the school's work for students..

Bakgrund: Att sövas är en av de mest stressfyllda erfarenheter ett barn kan få i samband medsjukhusvistelse.

Familjefokuserad förberedelse i både skriftlig och muntlig form och terapeutisk lekminskar också barns oro. En tyst och lugn miljö bidrar till en lugnare insomning och även alternativmedicin i form av akupressur ger samma resultat.Slutsats: Med ganska enkla metoder kan barns oro inför anestesi och operation förebyggas. Alla destuderade metoderna har visat sig minska barns oro i jämförelse med det standardiseradeomhändertagandet..

This thesis means to find out how preschool teachers are working to demonstrate the importance of recycling and reuse for children. My hope is to contribute knowledge about various practical methods to establish the idea of sustainable development in the operation. I have used the method of qualitative research and done semi-structured interviews with preschool teachers on certified green flag preschools. The questions I have asked for example concerned how the preschool teachers have worked with recycling and reuse, how much the children have been able to influence and if other didactic subjects are implicated. Six interviews were made and these are summarized in the result part.

Product development cycles become shorter and shorter. The time from idea to market has become an important competitive factor. Despite this, methods used for making the product development process faster are surrounded with uncertainty about their efficiency. The purpose of the thesis is to describe the pros and cons of ?best practice? methods for shortening lead times and how these methods effect the lead times in research and development.

???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.

The subject of this master thesis is co-operation between archives, libraries and museums. The purpose is twofold: 1 To map out activities within the area to get an overall picture. The mapping is done by studies of documents and consists of international outlooks and an overview of national and regional projects and reports; 2 To investigate how leaders of the respective institutions within the various regions of Sweden apprehend co-operation between the three sectors. The empirical study is accomplished by inquiries and is mainly qualitative. An intermediate purpose of this essay is to try using grounded theory to treat and analyse the gathered material.

The aim of this study was to examine how the activities of two preschools develop the language in matter of the teacher?s work of procedure. The following research questions were essential for the survey and therefore formed the basis of the examination:How do the teachers in both preschools work in a language evolving way?What significance does the environment have for the language development?Are there similarities and differences between the preschools in their language development approach?The study is based on a qualitative method, where the teachers of both preschools were interviewed with the purpose of obtaining information. The teacher?s statements and interviews were analyzed in relation to previous research, where the theories of different writers form the base of the theoretical connection to the study.The teachers view in developing the language regarding to their aspirations in measuring the language an important position in their operation, can be portraied as the conclusions of this study.

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

The purpose of this study was to investigate how the social services and the police co-operate with each other when they come into contact with an individual within their realms of influence. It has been shown in a report by Fridolf (2008) that co-operation is not the aim itself but used as a mean to reach for better processes and better results. We have used qualitative interviews in the study, where three social workers and three policemen have participated from the same municipality to answer our questions. To analyze our result we have used system theory and organization theory. The result of our study shows that within this specific municipality the two agencies co-operate very well.
