Möjligheten att snabbt kunna utvärdera system är något som blir alltmer aktuellt och populärt. Två metoder som ofta kombineras för att kunna få svar på användares upplevelse och specifika problem med system är användbarhetsenkäter och prototyptestning. Frågan är dock om det finns någon användbarhetsenkät som utvärderar lo-fiprototyper bättre än andra, och hur pass lika lo-fiprototyper utvärderas av olika användbarhetsenkäter.Denna uppsats handlar om hur pass lika användbarhetsenkäterna System Usability Scale (SUS) och Post-Study System Usability Questionnaire (PSSUQ) utvärderar en lo-fiprototyp och om det finns några praktiska skillnader med enkäterna som underlättar eller försvårar när man utvärderar en lo-fiprototyp. Lo-fi-prototypen som testades var en tidig, pappersbaserad version av en att-göralista för handläggare. Testdeltagarna fick först testa att utföra ett par scenarion och interagera med prototypen under 10-15 min, de fick sedan fylla i båda enkäter.Resultaten visade på indikationer att poängen som produceras av SUS och PSSUQ vid lo-fiprototyptestning är lika, men att det skulle behövas vidare studier med fler testdeltagare för att kunna säga detta säkert.

The Swedish state and educational system are secular, so to say they do not depend on the former protestant state church anymore. Many people in Sweden are also secular. Even so, in school teachers meet students with a religious faith. The purpose of this study is to examine how teachers without a religious belonging experience the encounter with religious students. The method used was semistructured interviews with five teachers in a upper secondary school in a multicultural suburb of Stockholm.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

The authors study the effects of brand salience on how consumers form brand attitudes and how consumers value the importance of various brand attributes. The study was conducted through two separate tests, the one focusing on the link between brand salience and brand attitudes and the other focusing on the link between brand salience and evaluations of attribute importance. Both tests measured brand salience as the ease with which brands are recalled by respondents who have been cued with a specific product category. The results show that brand salience has direct effects on both brand attitudes and the evaluation of attribute importance. As brands are recalled, high brand salience for a brand creates a more positive attitude towards that brand in the mind of the consumer.

This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..

Introduction: Balance is a complicated term which includes a static, dynamic and functional part. These parts have, during a long period of time, been included into the existing training programs through several different balance exercises, which aim to prevent sports injuries mostly focused on the knee and ankle. In floorball these injuries are common and a sports injury prevention program is required.Purpose: The purpose is to explain the balance term and relate it to injury prevention training and the existing theories. A second purpose is to see whether five weeks of balance training increases the balance ability in female floorball players and thereby increase the test values in the two tests.Method: Twenty female floorball players participated in the study and were divided into a training group and a control group. They performed a Star excursion balance test (SEBT) and a Multiple single leg hop stabilization test (MSLHST) before and after a five week training period, containing exercises of balance.Results: The training group showed improvement after the training period, however only one significant result was found.

In view of the difficulty of recruiting staff to care profession and in terms of the increasing need to find ways of ensuring a good language level in the profession, have an interest in language tests been revealed. The purpose of this paper is therefore to highlight the use of language tests for admission to the care courses for adults in Värmland. What provided This is a survey of the prevalence and an examination of the validity of the test. The issue that this study assumed is: How is language test in connection with admission to the certified health and social care courses for adults in Värmland? How well correlates intent of the use of the language test with the test's validity and reliability?The methods used to seek answers to these questions has been a combination of questionnaires and experiments.

In this project we have explored digital tools for service management on the bicycle paths of Malmö. This was done through the participation of citizens in order to attempt to discern how such interactions can be eased using a mobile app, as well as how this app can be designed in order to appear trustworthy with user friendly interactions. We have explored this field by using goal-oriented design through interviews, prototyping and user tests. We have created a digital prototype as a possible solution for how the interactions can be done. Throughout the process interviews were held and user tests with selected members of the user group. To explore the concepts we have used paper prototypes in order to establish the design and then defining the interactions with the help of a digital prototype. Finally we have concluded that a general app for bikers in the city would be functional and that a longer study in the effects of such an app would be interesting as a continuation of this work..

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

This study aimed to explore how 31 collage students' cognitive performance and their ability to create false memories were affected by the exposure of an extraneous background noise. The studies main hypotheses were based on previous research on how extraneous noise affect the cognitive ability and the creation of false memories: 1) that an extraneous background noise increases the ability to create false memories, 2) that an extraneous background noise impairs the learning of cognitive information, 3) that an extraneous background noise contributes to an increased representation of fictional words, 4) that an extraneous background noise impedes the ability to understand speech . The results showed a tendency in which false memories increased in the condition without background noise, a result which goes in the opposite direction of the hypothesis. Furthermore, the result supported the hypothesis that the extraneous background noise impairs the learning of cognitive information. The results also showed that there was no effect between the conditions regarding the representation of fictional information.

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

Tal- och röstförändringar är vanligt förekommande hos personer med Parkinsons sjukdom. Dessa påverkar ofta talarens förståelighet men kan också ha en negativ inverkan på talets naturlighet. Forskning angående vilka faktorer som påverkar talets naturlighet är i dagsläget begränsad, varför föreliggande studie har genomförts.Syftet med studien var att undersöka huruvida den uppfattade talnaturligheten kunde härledas till några specifika tal- och röstparametrar. I föreliggande studie konstruerades ett testbatteri för att elicitera talmaterial från åtta personer med Parkinsons sjukdom. Forskningspersonernas röster spelades in och inspelningarna graderades sedan av 27 naiva lyssnare gällande förståelighet och talnaturlighet.

Tillverkning av kemikalier för bl.a. pappers- och massa industri är en väsentlig del av Wibax koncernens verksamhet. En ny produktionsanläggning för framställning av flytande aluminiumsulfat, WiAL, togs i bruk i december 2004. Trots att framställningen av aluminiumsulfat inte är särskilt komplicerad, bör den ändå vara vältrimmad för att vara lönsam för företaget självt och ge en produkt av bästa kvalitet för Wibax kunder. Eftersom anläggning var helt ny saknade den historia och det fanns ett behov av att kartlägga processen och studera hur den uppförde sig.

New tools for the assessment of aphasia are important for bothclinical work and research. To see how they relate to already existing testscan increase their usefulness. Western Aphasia Battery ? Revised was translatedto Swedish and compared with the Swedish aphasia test A-ning, partlyto compare content and partly to see how sixteen people aged between 22and 92 with aphasia performed on the tests. The subtests did not correspondcompletely and the type of items included varied a lot.
