Automatiska GUI-test : En teoretisk och praktisk studie för hållbarare test

To automate software testing is an investment, and that makes it important to have good knowledge about automation before an implementation is made. In this master thesis a study about automated testing is carried out. The study also includes a closer look at the testing tool TestComplete. TestComplete is one out of many tools on the market that is developed for automated GUI testing and the goal is to get a picture of how well the tool can adjust to CC Systems own applications. Studies show that it is hard to write lasting test scripts.

Ny produktdesign och tillverkningsmetod för en effektivare produktion

Fagerhult Belysning AB i Örnsköldsvik är en armaturtillverkare som har försett IKEA med armaturer till innertaken i deras varuhus. På grund av att en konkurrent har sänkt priset på sina armaturer och där med tagit över armaturordern till IKEA, vill Fagerhult sänka sin tillverkningskostnad och därmed åter kunna få leverera till IKEA. Examensarbetet har haft som mål att kunna hitta ett sätt att kunna tillverka bländskyddet som ingår i armaturen till en lägre kostnad. Fagerhult hade vid arbetets början en prototyp av ett nytt bländskydd kallat Beta Economic. Beta Economic är ett bländskydd som har få ingående delar i förhållande till ett traditionellt bländskydd samt att det är bättre anpassat till att kunna automatmonteras. Arbetet har resulterat i att bländskyddet Beta Economic är färdigställt kontruktionsmässigt och klart för produktion.

Effekt av naturligt förekommande beta-glukan hos vuxna med hyperkolesterolemi ? en systematisk översiktsartikel med fokus på livsmedel i Svensk handel.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: The effect of naturally existent beta-glucan in adults with hypercholesterolemia. - a systematic review with focus on the Swedish food market.Author: Ida Edman Hellberg, Frida HanssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 01, 2014Background EFSA states in 2010 that there are good evidence that three grams of beta-glucan/day from oat as a part of a balanced diet, has a positive effect on total cholesterol and LDL.Objective Evaluate if there is evidence for primary treatment of lifestyle related hypercholesterolemia with products naturally containing beta-glucan.Search strategyIn February 2014 the databases PubMed and Scopus were used for article research. The search terms used were; cholesterol level, beta-glucan, hypercholesterolemia, oat and barley.Selection criteria Articles, written in Swedish and English, on RCT-studies conducted on otherwise healthy adults with hypercholesterolemia (serum cholesterol >5,0 mmol/L) were included. The intervention product must naturally contain beta-glucan, and an equally product should be retailed in Swedish grocery stores. The control group needed to be supplied with a placebo product and the participants could not be on any lipid-lowering medication.

Funktionell testning av webbplatser : En fallstudie

Websites are often developed by small businesses, organizations or individuals which may lead to that the testing gets left behind; the focus is on getting a finished product that can be deployed as quickly and as cheaply as possible.Functional testing is important also for websites and a variety of aids exist. With the right tools and methods the development work is facilitated, and it leads to products with fewer faults.This report shows in the form of a case study how an appropriate tool for functional testing can be selected and how it can be used within development of a website. An analysis of the tools available is reported and JSystem is selected as the most appropriate for this case.It turned out that JSystem could not be used fully as intended in terms of deployment, but a well-functioning alternative solution was developed.A number of test cases were created without any unsolvable problems and JSystem performed well. In JSystem test cases in Java are created in Java, which gives a high flexibility..

En studie om elever i årskurs nio, identitet, ungdomskultur och prövandet av narkotika

The purpose of our study was to look at the connection between theories, research work and concepts when it comes to teenagers and the testing of drugs. The theories we have used are Erikssons development theory, psychoanalysis and labelling theory. Concepts that we focused on for our study were youthculture, the search for identity and the testing of drugs. We did this by asking students, in ninth grade, to fill in questionnaire and interviews.Teenagers find themselves in a confusing stage in life and in a search for their identities they test many different things. The youthculture can be a contributing factor to them testing drugs.

Systematisk risk och avkastning på en volatil samt stabil marknad : En undersökning på den svenska aktiemarknaden

Background: Since the early 60?s, the CAPM or Capital Asset Pricing Model, has been an invaluable tool for assessing an asset's expected return, assuming that the asset is added to an already well-diversified portfolio of assets. CAPM theory assume that the unsystematic risk can be diversified and that the systematic, market-specific, risk is determined by the Beta value, from the Greek ?. An investor who takes big risks expect higher returns.One of the CAPM?s basic assumptions is that disruption in the market is not taken into account.

Prediktering av komponenters mognad/kvalitet utifrån felkodsutfall

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.

Rysslandsfonder : En analys av utveckling och risk mellan åren 1999 och 2005

Rysslandsfonder är en av många fonder som finns tillgängliga för att investera i. Ryssland har haft en starkutveckling de senaste åren. I uppsatsen görs en jämförelse av utveckling och risk mellan Rysslandsfonder och den svenska markanden representerad av SIX Return index. Utvecklingen hos Rysslandsfonderna har månadsvis under perioden 1999-2005 varit betydligt mer gynnsam än för det representerade Sverige index. Risken med standardavvikelse som en indikator för detta visar att det innebär en större risk att investera i Rysslandsfonder.

Vitamin A och E i relation till hästutfodring :

The purpose of this study was to examine vitamin A and E in equine nutrition and especially in relation to forages. A literature review was conducted to examine factors that influence the level of vitamins present in forage, the vitamin A and E requirement of horses, and the absorption of vitamin A and E in horses. The influence of DM level on alpha-tocopherol and beta-carotene content in ensiled forage was investigated in a controlled ensiling study using baled silage and haylage. The results from the ensiling study were combined with data of vitamin A and E concentrations collected from literature. Calculations were done to theoretically establish how well the vitamin content in ensiled forage can cover the maintenance requirements of vitamin A and E in horses.

A porcine type 1 Diabetes Mellitus model, for non-invasive in vivo imaging of the glucagon-like peptide-1 receptor in the pancreas, using [68Ga]Ga-DO3A-VS-Cys40-conjugated synthetic exendin-4 in PET-CT

Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.

Testramverk för distribuerade system

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.

Texturbestämning genom fält-, pipett- och hydrometermetoder :

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.

Utvärdering av mikrofon- och högtalarelement för högtalartelefonsapplikation

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..

Är ett framtida vaccin mot Alzheimers sjukdom möjligt?

Alzheimers sjukdom är en smygande neurodegenerativ demenssjukdom som främst drabbar äldre och som karakteriseras av uppkomsten av amyloidplack och neurofibriller i hjärnan. De vanligaste symptomen är demens, kognitiva problem, inbillningar och aggressivitet. Alzheimer förekommer i två olika former, presenil och senil alzheimer. Den fullständiga mekanismen bakom alzheimer är ännu okänd men två proteiner, beta-amyloid och tau, anses ligga bakom orsaken till alzheimer. Ett tredje inblandat protein som man funnit via genetisk analys är apolipoprotein E.
