Kultur och ekologi i Amazonas: GIS-bearbetning av historiska data om indianfolkens utbredning
This study deals with some contested issues regarding prehistoric cultural development in Amazonia and the colonial impact on the native inhabitants of the area. It focuses on the relation between groups belonging the language families of Tupí and Gê, on one hand, and the different ecological zones that they inhabit, on the other. GIS mapping is used to visualise the distribution and movements of these groups in relation to ecology and the impact of European colonization. GIS is shown to be a useful methodology for analysing historical data derived from written sources and maps. The results of these analyses are discussed in the light of different theoretical perspectives.

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.
Strategiskt beslutsfattande : hur svenska lantbrukare agerar för att anpassa sig till sockerreformen
A severe profitability decline in sugar beet production in all of Europe is one of the consequences of the latest reform of the EU sugar regime. In south of Sweden, sugar beets is the crop that has been the most profitable by far for the last decade. The high profitability has contributed to the high rate of increase in the price of land and has restrained the structural change towards a more effective agriculture. Because of the reform, all sugar beet producers are facing diminishing income and must find ways to compensate this.
The aim of this master thesis is to study how Swedish farmers adapt to the sugar beet reform. A questionnaire was sent to 354 randomly selected sugar beet producers.
Närvarodetektor med IR och ultraljud
En närvarodetektor i form av en IR-detektor uppfyllde inte de önskade kraven och Eluw Electronic AB hade planer på att utveckla produkten vidare. IR-detektorn registrerar endast rörelse på en person vilket inte alltid är tillräckligt i företagets anläggningar. En person som inte är i rörelse måste också detekteras för att upprätthålla säkerheten runt en specifik anläggning. Företaget efterfrågade en närvarodetektor som klarade båda dessa detekteringar. Ett examensarbete på Luleå tekniska universitet löste uppgiften och en väl fungerande närvarodetektor med IR och ultraljud har utvecklats.
Gratis pengar? - om sponsring av kultur
The purpose of this master thesis is to study sponsoring of culture. The questions asked are: What are the reasons for sponsoring? What are the advantages of sponsoring? What are the disadvantages of sponsoring? What is the relation between public grants and sponsoring? The thesis is based upon studies of literature and a case study in Malmoe. Malmoe Public Library received about a million SEK over a period of three years from the foundation of Foreningssparbanken Skane. The money finances two projects, one with new books, Nyhetstorget, and one with strengthened information for small companies, Projekt Förstärkt Näringslivsinformation.
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..
Att bygga kundrelationer med hjälp av communities
The advancements in digital technology and its availability contribute to the transfer of companycentricproduct development and value creation to networks or communities. It also changes the basisfor creation of customer relationships as described in previous research on Customer relationshipmanagement (CRM). The purpose of this case study was to gain an understanding of how companieslike our case study object Memoto who developed a physical product which gets added-value fromdigital product-related services looks upon product-centered communities as a way of buildingcustomer relationships. How Memoto looks upon incentives for participation in product-centeredcommunities was also examined.Our research indicated that firms in the start-up phase (which Memoto was when this study wasconducted) initially want to have more control over the process of innovation and hence have directcontact with end-customers. The reason for this is because they see a need to define the basis forfurther innovation work.
Does nuclear power plants affect house prices? : a hedonic price model of Forsmark nuclear power plant
Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.
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.
En bakgrund till skadorna på Slussens bärande konstruktioner
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
