Volymsrapportering vid drivningsarbete

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

Hur inverkar kontrollbordet på frekvenskurvan vid lyssningsposition i kontrollrummet när placeringar av högtalaren och lyssningsposition placerats efter ITU-R BS.1116-1 rekommendation?

The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.

Benchmarking som metod ? ett aktionsforskningsprojekt vid Valdemarsviks bibliotek.

The main purpose of this Master?s thesis is to do a benchmarking study of the marketing activities at the public library of Valdemarsvik. The purpose is also to describe and get a deeper understanding of benchmarking as a method for improving library activity. Four major problem areas are addressed: How can one use benchmarking as a tool to achieve change? How can one learn with benchmarking? What similarities and differences are there between benchmarking and other similar methods for competence development? Is benchmarking better than other similar methods for competence development? The empirical approach was qualitative and the method chosen was action research.

Kan instruktioner om en rättvis och likabehandlande rekrytering leda till minskad diskriminering?

This study examined if individuals act in a less discriminating way and in a more fair way when they receive instructions about justice and not being discriminating while recruiting. 96 randomly assigned students at the University of Lund participated in this study. The participants were informed that they would act as a recruiter. They would then choose and place three of the best personal record in order of preference. There were three different kinds of company policies/instructions.

Minkvalpars beteende i större berikade burar vid olika gruppstorlek :

Farmed mink often perform stereotypic behaviours which is considered to be a sign of reduced welfare. Previous studies have shown that enriched cages can reduce the frequency of performed stereotypies. Most studies on mink in Sweden have been done on adults. The aim of this study was to investigate if larger enriched cages with two or four mink kits reduce stereotypies in mink kits during their growth period in comparison to traditional cages. In the present study the behaviours of mink kits that were kept in four different treatments at a private mink farm were recorded. Traditional cages with two mink kits were used as a reference and the other treatments consisted of larger cages with shelves with two kits, larger cages with shelves and a plastic cylinder with two kits, and larger cages with shelves with four kits.

Detection of interesting areas in images by using convexity and rotational symmetries

There are several methods avaliable to find areas of interest, but most fail at detecting such areas in cluttered scenes. In this paper two methods will be presented and tested in a qualitative perspective. The first is the darg operator, which is used to detect three dimensional convex or concave objects by calculating the derivative of the argument of the gradient in one direction of four rotated versions. The four versions are thereafter added together in their original orientation. A multi scale version is recommended to avoid the problem that the standard deviation of the Gaussians, combined with the derivatives, controls the scale of the object, which is detected.

Modus vivendi. : Om könsidentitetens motstånd och beständighet i kvinnodominerade yrken.

The aim for this study was to find out what strategies women use to not react against inequality and sexist prejudice. In the study I used a critical realistic approach through, primary, the social ontology presented by Margaret S. Archer. The study focus on both the women?s construction of femininity and their construction of masculinity and what directions it constitutes for the women?s social orientation.

Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

Den ledande kvinnan : En studie av ledarskapsbeteenden i fyra olika branscher

The debate about women and equality is a very burning issue in the Swedish society today. There are a lot of articles, TV-programs, books and web sites treating the position of female leaders today. There are also a lot of myths strongly attached to our minds hindering the equalization process between men and women.The main purpose of our study was to look at women as leaders and identify potential tendencies in businesses sectors dominated by mainly men or women. We also wanted to find out whether leadership behavior is more or less oriented towards relations- or task in any of the chosen sectors. It was even in our interest to see if our chosen respondents supported the myths in our society about male and female qualities.We interviewed 20 women in four different sectors, two dominated by men (Computer/It, Transport) and two dominated by women (School, Healthcare).

Processinriktat och resultatinriktat motivationsklimat på svenska och spanska högstadieskolor

Studien processinriktat och resultatinriktat motivationsklimat på svenska och spanska högstadieskolor undersöker skillnader och likheter inom processinriktat och resultatinriktat klimat. I denna studie undersöks det hur dessa två klimat ser ut på svenska och spanska skolor och detta ur svenska och spanska idrottslärares perspektiv. I studien används Nicholls (1989) teori om de två motivationsklimaten. Empirin är inhämtad via semistrukturerade intervjuer med idrottslärare på tre svenska och tre spanska högstadieskolor. Detta i kombination med Nicholls (1989) teori och andra modeller, ligger till grund för den senare gjorda analysen.

Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

Från Monopol Till Konkurrens : Telias hantering av den ökande konkurrensen genom förändrade marknadsföringsstrategier

The Swedish telecommunication market was prior to the official deregulation 1975 characterized by Telia?s former monopoly position. This thesis studies how the deregulation of the market, and the thereby increasing competition, has affected Telia and how it has influenced Telia?s marketing strategies.The theoretical framework, from which the conclusions will be made, is a combination of the theory about strategic learning behaviours by Slater et al, and Grönroos? theory about a marketing continuum. The empirical work material is the result from two interviews with former key figures at Telia, and a briefing of Telia?s annual report between the years 1993 and 2006.Research findings indicate that Telia has gone from being product oriented with a strong technical focus, to becoming gradually more market oriented with competition orientation but foremost customer orientation as their most distinguished learning behaviours.

Asyl och rätten att definiera sexualitet

The purpose of this paper is to examine the constructions of sexuality, which are produced when judgments concerning asylum are made, based on an asylum seeker?s sexual orientation. The question formulations are the following: Which constructions of sexuality are produced when necessary condition, fear of persecution due to sexual orientation, is applied in judgments regarding refugee status? Furthermore, how constructions of sexuality differ in the judgments where the asylum seeker has been consented and rejected is investigated. The empirical material consists of 13 judgments, which were announced between the years 2009-2013 by the Migration court.

Factors affecting bark-stripping by red deer (Cervus elaphus) : the importance of landscape structure and forage availability

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
