Övertoner orsakade av varvtalsstyrda motordrifter ger problem i industrisystem. Syftet med studien är att identifiera problemen och ge rekommendationer för att undvika dem. Studien utfördes som examensjobb på KTH för konsultföretaget Ramböll. En litteraturstudie i ämnet kombinerades med elkvalitémätningar på drifter hos Sandvik Mining.Elkvalitéproblem orsakade av varvtalsstyrda motordrifter kommer till stor del av att frekvensstyrningen ger olinjärt strömuttag som, om nätet inte är tillräckligt starkt, påverkar spänningskvalitén. Problemen kan vara driftstopp, störd utrustning och ökat slitage på utrustning för att nämna några.Denna studie visar att vid ändringar i system innehållande övertoner kan framtida övertonshalter approximeras för vissa fall.

1 January 2005 came the new reconstructed version of IAS 40. It came to compensate the earlier ÅRL and FAR who was applied within the European Union. These new standards came to be called as IAS/IFRS. The standards? are supposed to make sure that the differences between the different countries won?t be so split.

Sweden?s most trusted news distributor, Sveriges Radio (Swedish Public Service radio broadcaster), has high ambitions with the journalism it broadcasts ? especially when it comes to gender equality and diversity. This thesis examines how gender is constructed in Dagens Eko (Today?s Echo) to find if and how power structures are expressed language-wise. Queer theory is used to look at how gender is constructed and how one can look at, and question, gender and gender hierarchies.

This pilot study describes a therapy method for persons withBroca´s aphasia. This method is based on the mapping hypothesis (Schwartz,Saffran & Marin 1980). The mapping hypothesis is based on the assumptionthat agrammatism is caused by an inability to combine syntactic structurewith thematic roles. This study describes a combination of the therapymethod mentioned above and the Everyday life activities photo series (ELA,Stark 1992). The aim of the study was to investigate if therapy based on awritten sentence/picture format is a viable starting-point for future research.The therapy presented combined written sentences with pictures describingeveryday life activities.

To be competitive in the corporate climate of today it is important to have effective logistic activities. A common resource within the internal logistics is forklift trucks, which are used to lift and transport material. It becomes more and more important to decide whether to buy, lease or rent the forklifts to obtain an optimal economic situation. Many companies have issues with internal pricing. It is difficult to price products and services correctly. It is common to price the overall instead of what it really costs.The purpose of the thesis is to present a model for the acquisition of forklifts for internal logistic operations, regarding financing and internal pricing, to obtain economic effectiveness and an optimal forklift fleet size. The study focused on a specific research question, and for this purpose interviews with experts were held, observations were made and a literature study was done.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.

This thesis on the sustainable urban development has the intent to discuss the conservator?s position in alteration of the built environment. An essential component of the thesis consists of a case study in the form of an entry in an open architectural competition for the development of Furuset, an urban residential area in Norway. The thesis? discussion is based on two approaches to change and socio-economic transformations, considered being dominant within the heritage theory and practice: the production of ideas and great narratives and conservation as an instrumental tool.

This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.

The State Institution for Education of Feebleminded Girls was one of the two swedish educational institutions established under state management in the 1920s and came to be the starting point for further government operations for the mentally deficient. The purpose of this paper was to investigate the activities of the State Institution for Education of Feebleminded Girls, out of what needs the institution filled in Sweden?s care for the mentally deficient. The institution has tried to be understood from the view of eugenics and the perspective of children that was current during the 1900s first half.To fulfill the purpose of the study, the archives for the State Institution for Education of Feebleminded Girls was studied and analyzed with basis of previous research on Sweden?s care for the mentally deficient and the impact from eugenics and Sweden?s child perspective.The study shows that the State Institution for Education of Feebleminded Girls mostly existed to educate students and adapt them to the community, which the institution did by education, disciplinary interventions and sterilizations.

Uppsalahem is the leading housing corporation in Uppsala with its over 160 real estate properties. Uppsalahem is owned by the municipality of Uppsala, which has a climate and energy goal that aims for 100 MW of solar energy to be installed in Uppsala by 2030. The 100 MW goal, combined with Uppsalahem?s environmental policy, is a strong incentive to investigate the possibility of installing PV modules on the many available roof areas that Uppsalahem possesses. The objective of this thesis is to create a foundation for future decisions regarding PV systems for Uppsalahem.

The aim of this thesis is to evaluate a Swedish subject headings list for childrens and young adults fiction, from the perspective of consistency, and to analyze this concept's importance as a tool for measuring indexing quality. Another aim is to examine how librarians view the subject headings list as an aid for indexing fiction. The main questions are: How does the degree of consistency change when using a subject headings list for indexing fiction compared to free indexing? How does indexing change according to the facets Form/Genre, Time, Space, Matter and Person when using the list? What do consistency calculations reveal about indexing quality? How do the participants look upon the list as an aid for indexing? The empirical material consists of results from two different indexings of fiction, conducted by librarians. Consistency is calculated using Hoopers and Rollings algorithms.
