A comparison of methods to assess site index in young Norway spruce stands

This study investigates whether the site index curve method (SICM) and the growth intercept method (GIM) can be used for site index predictions in younger Norway spruce (Picea abies (L.) Karst.) stands than recommended by current guidelines. For SICM it was thus investigated whether the method could be used for stands younger than ten years, and for GIM it was tested whether a starting point for the intercept measurements could be used below the recommended 2.5 meter. This was tested based on measurements taken from experimental stands in Tönnersjöheden Research Forest. For GIM it was found that the method can only be used when the TH-trees of a stand have five complete intercepts above 2.5 meters. For the method to be applicable beyond this, it will be necessary to adapt the underlying equations, perhaps following the Canadian example where a 1.3 meter intercept start is used. In conclusion it is not currently possible to apply the approach beyond the current recommendations. For SICM, SI predictions are accurate for the study area already form year three.

Estimering av GPS pålitlighet och GPS/INS fusion

The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

Meningslöshet och repetition i Cirkusdirektören och Ballerinan : En undersökning i den absurda teaterns stilistik

Futurum.kom is a collaborative marketing project with the aim of strengthening the internal organization of Länsbibliotek Sydost, Regionbibliotek Kalmar and the 25 public libraries within the southeast region. The project intends to externally build the brands of the public libraries in Blekinge, Kalmar and Kronobergs län. This thesis is a study and evaluation of the implementation and results of Futurum.kom?s first campaign "Låna dig rik" at a public library. The analysis is based on the following issues:? What goals does the library have with the "Låna dig rik"-campaign.? What is the feedback from the staff's experience of the users in terms of needs and demands?? In which way does the library choose to implement the marketing campaign and what role do the users have in this process?? What is the internal performance of the library's marketing campaign, what was the experience of the staff of the campaign?? What is the external result of the library's marketing campaign?The method is based on a case study of a single library, with a series of interviews and document analysis of written and electronic documents.

Utveckling av metoder att mäta centrering av skruvhål i skär

There have been, in some rare cases, difficulties with clamping of inserts with U-holesin their tool holder. According to the complaints, the inserts could not be properlyclamped or could fracture when clamped. A study has shown that variations inclamping behaviour are mainly depending by the position of the screw hole in the toolholder and the centering of the screw hole in the insert.The focus of this project has been the centering of screw hole in insert. It has beenshown that the screw holes are not always enough centered in the insert. Theproblem may occur after a certain step in the production, i.e.

Effektiv ordinlärning? : En studie av aktiv ordinlärning i engelska inom gymnasieskolan

The purpose of this essay is to discuss and compare different ways of learning new words and expanding your vocabulary in a foreign language. This is done by an examination of relevant literature and available research, as well as by an empirical study with two upper secondary school classes, in which two different methods are put to the test: one traditional method of the kind that is found to be most common in second language acquisition, and one designed to take existing research into account. The results show that, although effective in the initial stages of acquisition, the traditional method, where words are learned in isolation and via translation to L1, results in a very limited form of knowledge. A big part of the words acquired via this method is also forgotten soon afterwards. The other method, where words were learned and tested in its proper context, was found to result in a broader form of vocabulary knowledge, covering more aspects, and that remained over time.

ELever möter Lagerlöf : en responsstudie av gymnasieelevers första möte med en text

 This study examines the way Swedish students in Upper Secondary School respond to two excerpts from a classic Swedish novel. The paper?s aim is both to give an overview over some of the theoretical concepts concerning the field of reader-response criticism, and to describe and analyse what the students experience in their first meeting with an older text. The background to my interest is the many studies showing that young readers regard reading of fiction in school as boring. By using the method of written reading responses I want to contribute to a deeper understanding of how an older text can be received, understood and engage its readers.

Sjuksköterskans arbete med Manchestertriage : arbetstillfredsställelse och kompetens

Background: Triage is the sorting of patients according to the severity of medical assessment. Triage has a long history of use in Anglo-Saxon countries but is a fairly new method in Sweden. Researchers have described the Manchester triage group method (MTS) and a literature review of the concept; working contentment and competence focusing on triage. Aim: The ambition with this study was to describe a number of triage nurses working conditions. The research questions were; working with MTS- does it bring work contentment? What kind of competence is needed? Method: Data was collected from 74 triage nurses by a questionnaire containing 37 questions and two questions provided the nurses the opportunities to describe their triage experiences.

Voltage Sags Indices and Statistics

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Skillnader i konsumentbeteende mellan försäljningskanaler

In todays' society e-commerce is growing at a rapid speed. 4,6 % of all retail sales on the Swedish market are done on the Internet. In the makeup category, which will be the category of focus in this study, 9 % of all the sales were done on the Internet during the last quarter of 2011. As it is today many suppliers do not have enough knowledge about e-commerce and instead of focusing on the development of the channel the focus should instead be on the development of the users of the channel.The purpose of this study is to understand the buying process with respect to the existing theories. The focus will be on the two stages information search and evaluation of alternatives.

Kamratbedömning i svenska : Nio lärares tankar och erfarenheter

This paper studies how peer assessment is used as a strategy to improve young learners' results in Swedish as a school subject. Nine teachers are interviewed about their use of the method on 7-12-year-old pupils. Comparisons are made between the interviews and Swedish and international discussion on peer assessment. There are similarities between the practice of the teachers and what is said in the litterature about the method and its advantages and drawbacks. The teachers tend to emphasize the social aspects more, though.

Förskolechefens beslut- att välja inskolningsmetod

I have written an experiential essay about my role as a preschool director and the important work decisions that I face. What is best for the child? That is something that I think is important to take into consideration.In the narrative, I describe how an induction occurs at my preschool. We use an "old" tried and true method which spans two to three weeks, which I believe is best for children under the age of two. They need to first connect withone educator who they are comfortable with before they are secure enough to play and explore the environment of the preschool.In recent years, another method has emerged which is shorter and which has quickly became popular in many preschools.

Det här är min skolgård : tillvägagångssätt för medbestämmande och ökad trivsel i skolmiljön

For several years has there been a leading line from the government and the municipalities in Sweden to invest in schools and school grounds. The outdoor environment of schools has been rediscovered and given a greater importance. Investments have been made both practically with reconstruction and in a research context. Although, my work started with an assumption that these investments were mainly made at primary schools, and that secondary schools were set aside. The thesis This is my schoolyard.

Hur har det svenska handelsmönstret påverkats av ett medlemskap i EU?

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

Test av modeller för prioritering av förändringsförslag i Stora Enso Skog AB´s nya produktionsplaneringssystem VSOP

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
