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.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in Testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of Testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for Testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

The project deals with the evaluation and Testing of speaker and microphone elements as well as microphone cavity.The first part of the report comprises a comprehensive theoretical part about drivers, microphone elements, and to some extent microphone cavity.The goal was to , on the behalf of the company Limes Audio AB, develop proposals on microphone element and cavity as well as drivers for a speakerphone application, based on specific factors. The main factors were performance, price and form factor.The aim was to create the best possible conditions for Limes Audio's software developers to implement the company's audio-enhancing software, mainly adaptive echo cancellation.The Testing was carried out using Adobe Audition and MatLab. The test methods were developed in conjunction with Limes Audio and are described below.The project will result in suggestions for a speaker, a microphone and a cavity. The cavity were removed from the product because the results indicated that the cavity matter little for the end result.The report concludes with a discussion on how the measurements could have been enhanced to simplify the interpretation of the results and making the Testing more efficient..

Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of Testings.

In today?s IT world where software is constructed in a rapid pace, Testing has become a crucial area to master when Testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on Testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex Testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.

The City Library has a problem getting children interested in reading. Futhermore, there are no clear signs to aid children to navigate themselves to books targeted to their age group. To solve this problem, this thesis aims to design signs that is both illustrative and informative.Of the images that were tested during the research, I would assume that children in such a wide age range requires the simplest level of abstraction from Testing the three Testing icons, since the second level of abstraction was not interesting enough for the kids. The third, nearphotorealistic level was most liked by the children who were in the city library more often and looked for books themselves..

This study has researched how user click heatmaps and eye tracking can be utilized in usability Testing. We have used the tools SessionCam and Tobii. We designed a website for a small clothing store and conducted usability tests, in order to evaluate the users clicks and eye movements in relation to design choices on the website. The aim of this study was to research how these tools can be integrated in usability Testing and how results from the tests can be used to improve usability. We were able to use the recordings of clicks and eye movements and make design changes based on the findings.

The aim of this study is to examine the patient's understanding of the counselling while Testing for an STI. The method was an inquiry directed to patients at two receptions, where tests for STI are made, and on the Internet for patients who made a test within the last year. The study involves 95 participants, 39 answered the inquiry directly after the test. The main results show that most participants are positive to talk about their sexuality and sexual strategies with the personnel, irrespective of who takes the initiative to the counselling. Women are yet more negative then men to talk about their sexuality, even if the test is made voluntarily by the woman.

The effects of dexmedetomidine and butorphanol sedation on skin reactivity during intradermal Testing in healthy dogs were evaluated. The effects of dexmedetomidine and butorphanol were compared to medetomidine, a sedative agent having scientific proof of not interfering with skin test reactivity, in a randomised, double blind, cross over study performed on 8 adult dogs. The dogs were sedated with medetomidine (Domitor vet.®, 0,01 ml kg-1) intravenously, or dexmedetomidine and butorphanol intramuscularly (Dexdomitor vet.®, 0,01 ml kg-1; Dolorex vet., 0,01 ml kg-1) after which they received intradermal injections of positive control solutions (histamine 0,1 mg ml-1, 0,05 mg ml-1, 0,025 mg ml-1), a negative control solution (0,9 % NaCl) and allergen extract (Dermatophagoides farinae, Cladosporium and Artemisia vulgaris). After a wash out period the trial was repeated with a reversed sedation protocol.Skin reactivity (wheal size, induration and erythema) and quality of sedation (immobilization, response to stimuli and injections as well as over all working conditions) were evaluated. The combination of dexmedetomidine and butorphanol provided reliable, good sedation and analgesia without adverse effects.

During the past few years there has been an observed decrease in physical fitness within different patient groups. As a part of the rehabilitating physiotherapy treatment it is important to acknowledge the physical condition of the patient. Physical fitness Testing might be difficult due to physical limitations within different patient groups. A broad range of exercise tests is therefore of importance in clinical practice. The aim of this overview was to describe exercise tests used in rehabilitation contexts, and to define areas of use and restrictions.

There are several ways of conducting software Testing where some may include users and others may include personnel whose work task is to execute test on systems. Although most developers and project managers understand the point of Testing the system, it is not always being done and the most common reason is that there is no time for it. However, this is a false assumption as it may instead cause some bugs in the system that would not have been there in the first place if tests had been there to prevent bugs in the code.My purpose for this thesis was to find suggestions for changes in the development process in an ongoing project used by Acino and Svenska Försäkringsfabriken in order to increase the quality of the system used. In this thesis, I have approached the purpose by pursuing a case study of the two companies through observation and interviews. By doing this I acquired the relevant information to make suggestions for change.

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

This essay examines pull-out strength of threaded rods fixed into glulam timber. The technology is intended to be used in hidden joints between glulam components. The work began with a study of literature focusing on current research within the topic, mainly to create a base of knowledge before the Testing was initiated. Studies of scientific articles reveals a lack of research within this area, which makes it difficult to develop standards and calculation models for these joints. The drill holes in the tests have a diameter of 7 mm.
