Modellering och reglering av drivenheter i gaffeltruck
To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Studie av skyddsavstånd mellan bergvärmeanläggning och skyddsobjekt i ett vattenskyddsområde
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.
Att sätta fingret på emotionell intelligens - En kvalitativ studie om användningen av EQ-test i rekryteringsprocesser
Emotional intelligence (EQ) has been claimed to be the most critical factor in determining a person's success in life, both personal and professional. EQ highly affects academic and job performance, leadership, stress, and well-being but is still not widely accounted for in recruitment processes. During the last 20 years a large number of researchers have shown interest in the concept of emotional intelligence, but few have studied its practical implications and how EQ-tests are used as a selection tool in recruitment processes. To create an understanding of the motivation for using the test, as well as its role in recruitment decisions, qualitative interviews have been conducted with recruiters at companies in Stockholm, Sweden. All interviewed companies use the self-assessment test EQ:i 2.0.
Evaluation of a behaviour protocol for use in recording the behaviour of horses following administration of methadone
There is a need for correct and adequate pain assessment in horses. Methadone is used in pain management in horses but the full pharmacokinetic picture of methadone is not yet known. The aim of this pilot study was to develop a behaviour protocol and suggest a reliable recording method for use in a larger research project with an aim to potentially correlate behaviours to concentration of methadone in blood. In this study two coldblooded trotters were given methadone intravenously with doses of 0.1 mg/kg for horse 1 and 0.2 mg/kg for horse 2. The horses were videotaped pre and post methadone administration.
Val av teknik för hastighetsmätning i kallvalsverk
An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system. One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Google, Yahoo! och Live Search: en evaluering av tre webbsöktjänster
The purpose of this Master?s thesis is to evaluate three general query-based web search engines. The search engines chosen are Google, Yahoo! and Live Search. The topics, which where transformed into twenty queries, are based on real users? information needs, taken from an ask-a-question service.
Att utföra användarcentrerat arbete med små medel
Usability is a field within systems development which doesn?t get the attention it might deserve. Above all, it?s considered time consuming and expensive by many people in the industry. The current information regarding low-cost alternatives to achieve a more usable system seems to be almost non-existent.
Mixtekniker
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.
Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan
Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.
I huvudet på folkbibliotekarien ? En studie om folkbibliotekariers uppfattningar om lässtimulerande insatser
During the last ten years, PIRLS and PISA have evaluated the reading levels of children and youth around the world, sometimes with grim results. The Swedish evaluation show a constant decline in reading comprehension, and Sweden, which from the start produced one of the best results in the world, have plummeted to the bottom of the ranks. The librarians of the public library have extensive experience of working with different projects engaging children and youth in reading, and so they have a major part to play in this matter. Consequently, the aim of this study is to examine and describe the different perceptions the public librarians have of these projects. Four research questions were formulated, each focusing on the perceptions regarding different aspects of the reading promotion projects.
Vad håller vi egentligen på med? : en studie som granskar användandet av pedagogisk dokumentation utifrån förskolans uppdrag
In this study, we aim to analyze how the terms documentation and pedagogical documentation respectively are portrayed in the curriculum (skolverket 2010) as well as in the curriculum complementary material (skolverket 2012). The analysis is performed by use of critical discourse analysis. We used published research as a theoretical base to analyze the empirical data against. Our aim is to increase the understanding of how the terms documentation and pedagogical documentation are used in the various policy documents and what messages these documents relay concerning the aforementioned terms.We aim to give some answers to the following questions:How to interpret the term documentation in relation to the term pedagogical documentation.How to interpret the ways the terms are promoted in the policy documents. We conclude that the term documentation is vastly more open to interpretation than the term pedagogical documentation. We note that the curriculum exclusively use the term documentation and stress the importance of using a variety of documentation forms.
Seriemediet i bibliotekspressen 1960-1999
The purpose of this Master?s thesis is to study how the comics have been evaluated and debated in the Swedish library press from 1960 to 1999. Have they been seen as something good or something bad? What arguments have been put forward against them or in their defense? What kinds of development can be seen over time? The point of doing this, is of course that evaluation always plays a crucial part in library work. By studying how a "new" medium or art form has been evaluated in the past, we can hopefully gain a greater understanding of how today?s newcomers should best be treated.
Quantification of Tripeptidyl-peptidase II : Optimisation and evaluation of 3 assays
Abstract Tripeptidyl-peptidase II (TPPII), is present in most eukaryotic cells. It cuts tripeptides from the N-terminus of peptides and is especially important for degrading peptides longer than 15 amino acids. TPPII also tailors long peptides into suitable substrates for the enzymes which transport and produce the peptides that MHC I present. Increased levels of TPPII have also been found in certain cancer cells, thus it is of interest to determine if TPPII could be used as a tumour marker.The aim of this study was to optimise and evaluate 3 different methods for quantifying TPPII. Western blot, enzyme-linked immunosorbent assay (ELISA) and fluorophore-linked immunosorbent assay (FLISA) protocols were optimised regarding incubation times and antibody dilutions.
