Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses. Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months. In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.

Energimyndigheten har drivit ett projekt kallat ?Förbättrad energistatistik i bebyggelsen? för att få mer kunskap om energianvändningen i byggnader.  Denna rapport fokuserar på ?Mätning av hushållsel på apparatnivå? som var ett delprojekt.Diverse regressionsmodeller används i denna rapport för att undersöka sambandet mellan elanvändningen och de olika förklarande variablerna, som exempelvis hushållens bakgrundsvariabler, hushållstyp och geografiska läge, elförbrukningen av olika elapparater samt antalet elapparater.Datamaterialet innefattar 389 hushåll där de flesta är spridda runt om i Mälardalen. Ett fåtal mätningar gjordes på hushåll i Kiruna och Malmö.Slutsatsen vi kan dra från denna uppsats är att hushållens bakgrund, hustyp, geografiska läge och antal elapparater samt dessa apparaters typ har relevans för elförbrukningen i ett hushåll..

This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.

The main purpose of this Master?s thesis is to explore university librarians? thoughts about the future. The analytical focus is thus on the librarians? representations of the future. The theoretical framework used is narrative theory with a social constructionist viewpoint.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Sara Lidman?s second novel Hjortronlandet (1955) unfolds in the north of Sweden in the early 20th century. It describes the progress of modernity and the conflicting interests of an old local culture and a new more ?civilised? one. The two cultures are constituted by different value systems and in the novel they are represented by two neighbour communities.

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

The purpose of this paper is to investigate if a dynamic investment strategy on the Swedish asset market can accomplish better returns then a static investment strategy. The dynamic investment strategy is created by incorporating business cycle predictors and firm-level variables to predict future stock returns. The predictive regression is calculated wih 60 months of observation (1999 01-2005 12) and is then used to estimate future returns for 23 months in the period 2004 01 -2005 11. The structure of the regression, with linear functions of ? and ?, goes back to Shanken (1990) and Avramov and Chordia (2005) has had success with the variables chosen.

When the Tsunami occurred on Boxing Day 2004 it caused a major stress upon the governmental agencies in not only the affected areas but also in states that had a large number of citizens in the affected area. The governmental agencies were not prepared for the demands from the citizenry in these countries to deal with rescue and crisis management in areas situated halfway around the globe. This thesis main purpose is to research what the causal mechanisms of Sweden?s and Finland?s crisis management were through the method of process tracing. Taking its theoretical stance in Allison?s & Zelikow?s three models of decision making, the thesis compares the course of events of the first two critical days in Sweden and Finland to establish what mistakes were made during this critical period.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.
