En jämförelse mellan några multivariata data-analysmetoder

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.

Prestation vid sönderdelning av GROT med olika typer av maskiner

There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

Lilaköttig taggsvamp, Sárcodon fuligíneovioláceus : miljökrav i Sverige och en analys av vad som styr artens etablering

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

Artificiella neuronnät & biometri : -verifiering utav användare via tangentbordsskrivning

Detta arbete handlar om beteendeinriktad biometri och artificiella neuronnät av typen feedforward och hur de tillsammans kan användas för att verifiera användare. Det har av tidigare arbete bekräftats att det är möjligt att verifiera användare, men tidigare resultat har däremot inte utfört tester med avseende på avvikelser i data (beteende) och dess inverkan på verifieringen. Det är detta som utgör det huvudsakliga målet för detta arbete, nämligen att undersöka hur avvikelser i data påverkar verifiering och utifrån det också undersöka neuronnätens noggrannhet vid verifiering..

Kvinnors upplevelse av planerad hemförlossning i Skandinavien : Women´s experience of planned home birth in the Scandinavian countries

Background: In Sweden and Norway planned home birth is not included in the health care system. In Denmark women with expected low risk birth have the right to choose home birth. Registrations of home births in the Nordic countries are not completed and women?s experiences of planned home birth in Scandinavian context are not earlier described.Objective: The aim of this study was to describe women?s experiences of planned home birth in the Scandinavian countries.Design: Inductive content analysis.

Integrering av Bild och Svenska : Att skapa sammanhang i undervisningen

The purpose of my essay is to see how teachers are working to integrate the two subjects Art and Swedish in their teaching, and to see how this integration is made. What do teachers think about subject-integration? What are the positive effects of it? Are there any difficulties involved? Do the teachers prioritize cooperation with other subjects?To answer my questions I have interviewed eight teachers, four of them in upper secondary school and four in lower secondary school. I have also studied literature about subject-integration and children?s learning, curriculum?s and syllabi in the subjects of Art and Swedish.The results of my study show that the interviewed teachers are positive when it comes to integrating Art and Swedish and other subjects.

Hedge Fund Style Analysis, Is an Index-Based Approach Viable?

This thesis aims to open the Pandora?s Box of hedge fund styles through an index-based style analysis. This information asymmetry is due to both less strict disclosure requirements and inherent nature of hedge funds. We employ a multiple unconditional linear regression model wherein 23 Swedish hedge funds are regressed on 10 style indices. In addition to the increased interest in hedge funds and their performance drivers, our unique approach with regressing return on return motivates this study.

Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

Förändring eller förvaring bakom murarna? En intervjustudie om intagnas upplevelser av kriminalvårdspersonal

This paper presents an investigation into the relationship between inmates and staff in a high security prison in Sweden. The primary objectives are to investigate this relationship from an inmate perspective and to identify key factors that may promote or hinder rehabilitative interaction with staff. Empirical data utilized in this study consist of semi-structured interviews carried out by the authors with nine inmates currently in custody of the treatment facility within the prison and six inmates housed within the study facility. This data collection method is an extension of grounded theory and four key themes were generated from the data analysis. The first of these examines the effect of rule enforcement on prison atmosphere and subsequent staff/inmate relations.

Lärares uppfattningar om arbetet med återkoppling i en lärplattform

The students participating in my development work will work with a process book for handicraft studies. In the beginning of their studies, the students need practical knowledge about the development of the profession itself, but they also need to be challenged and learn how to solve problems on their own which will help them gain a deeper knowledge of the subject.    I focus on open questions to create a process with the students. This process is created when working with Solution-Focused-Education. Through ?assessment for learning? we can help the students to improve their self-assessment and understanding of the learning process.
