The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

This investigation is a pilot survey whose main purpose is to investigate with work evaluation and attitude analysis whether the orthopedists and surgeons work can be equaled, why the wages differences exists between women and men, and also which preventive measures the organization can use to even out the wages differences between the genders. In relation with the investigation I have applied the reflexive way of thinking to establish which difficulties come up in the work of gender-equality.The result?s from work evaluation displays that the works are equivalent but the salaries are not, which can depend on value discrimination,gender discrimination and the organization theory.Wages differences between women and men depend on, according to the informers, partly by historical explanation and partly by the old directors who was allowed to retain regular salary when theypost transformed. The common point of view is that men have a larger work experience and therefore a higher salary.The managements attitude towards gender-equality issues is of absolute importance in order to achieve and bring a change within the organization.The measure positive special treatment is proposed to be used as an improving method to achieve (gender)equality between the posts and to even out the wages difference between the sexes.To establish whether or not gender discrimination exist in the investigated organization there needs to be done a whole lot supplementary studies like a complete wage (salary) mapping which includes all supplements and more interviews among the organizations all occupation groups..

Today there is still irrelevant pay differential in society. In Sweden in 2010, the average pay differential was 15,4 percent between the sexes. Only 0,8 percent better than EU:s average.In Sweden the individual salaries increasingly have begun to characterize the Swedish labor market. Based on this, the aim of this study is to highlight the issue of equal pay between men and women from the perspective of individual salary. This would also been doing with a background in the regulatory environment of equal pay.When it comes to equality between women and men it is the area of labor law in EU who is the most developed and in Sweden this is the area who is most affected by EU law.

The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Bakgrunden till studien är mina egna tankar om hur de lönesättande samtalen inom arbetslivet egentligen fungerar nu när de har blivit alltmer vanliga på arbetsplatserna. Syftet med studien är dels att undersöka hur kommunikationen hanteras och upplevs under ett lönesättande samtal av medarbetare respektive ledare dels att utveckla kunskapen om vilken betydelse kommunikationens påverkan har för samspelet under det lönesättande samtalet. Studiens forskningsfråga har varit hur medarbetarna och ledarna upplever samspelet under samtalet, varför den sociokulturella teorin har använts tillsammans med andra kommunikativa begrepp och teorier. Studien har av den anledningen haft en fenomenologisk ansats för att få fram respondenternas subjektiva upplevelser av samspelet under det lönesättande samtalet. Som metod användes en öppen intervju med en frågeguide som innehåll ett antal olika teman som de olika respondenterna själva fick resonera kring.

This paper illustrates the working conditions at the copper factory in Åtvidaberg during 1800-1890 from different views. The highest salary was given to the building contractor. Thereafter came in order the rust turners, the garmaker, the melter, the ore booker, the factory supervisor and the garmaker hand. Also the rest of the working conditions for different employees might differ from each other in this order. The mine workers generally earned a little less than the other workers at the factory, and especially the workers in the Bersbo mine.

The aim of the study was to describe how hygienist`s receiving their certificate during 2003 and 2004, perceive their working situation, salary and impression of their first employment as a registered dental hygienist. A questionnaire was sent out to new dental hygienist`s examined year 2003 and 2004 in Sweden. Most of the new examined dental hygienist`s found the education adequate or more than adequate. A few individuals found it inadequate. The ones finding the education inadequate wanted more clinical practice and more training in administrative work.

Föreliggande uppsats behandlar lönesättning på den svenska arbetsmarknaden. Lönesättningen i Sverige är inte i vidare utsträckning reglerad i lag. Grunden för lönesättningen är att det råder avtalsfrihet och att det är upp till arbetsmarknadens parter att genom kollektivavtal reglera området. Kollektivavtalen innehåller olika typer av reglering avseende arbetsgivarens lönesättning, exempelvis anges ofta minimilöner samt utrymme för lönehöjningar vid lönerevision. Avtalen innehåller dessutom oftast lönesättningsprinciper för hur löneutrymmet ska fördelas mellan enskilda arbetstagare.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

The purpose of this thesis is to examine whether institutional ownership has an influence on CEO compensation in companies where the institutions have invested. In order to fulfil the purpose of the thesis a quantitative study was carried out within the Swedish corporate context where we have studied Swedish institutional investors and companies quoted on the Stockholm Stock Exchange. Our period of study was the financial year of 2007.The empirical questions at issue is; Was there a connection between Swedish institutional ownership and the size of the CEO compensation, and, does Swedish institutional ownership lead to a certain type of CEO compensation in terms of structure?Our results did not suggest that an increased institutional ownership neither leads to a certain type of salary level nor a certain kind of salary structure. These results contradict earlier American research, which has been done within this area and has previously shown a secured connection.The reasons for our results may be many and it is difficult to state any concrete conclusions to why we received differing results.

The aim of this thesis is to accomplish an understanding on how librarians experience their professional role at private companies. The study is based on qualitative interviews with persons who have a degree in Library and Information science, but does not work as an ordinary librarian. To answer why the respondents work at private companies, this thesis dwells on how the education in library and information science prepares their students to face an alternative career; why the respondents wants to work at private firms instead of a library; if the salary is a key factor in order to choose a career; if the respondents think the companies appreciate their qualifications, and finally, if the respondents think they intrude on other professions' territory? Working at a private company, with a degree in library- and information science, is not, according to the respondents, easy. Although appreciated by their knowledge in the field of information, the interviewees think that the title librarian is hard to cope with.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
