En beskrivning av manuellt test : Svagheter och styrkor med och utan stöd avett testverktyg

Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

Spännkraft på bandavskrapare : Utredning och konstruktion

This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

Användbarheten hos WNV: granskning av ett nytt icke-verbalt intelligenstest för barn

This paper investigates the usability of the intelligence test Wechsler Nonverbal Scale of Ability (WNV). Twenty four children in two different age-groups were tested with WNV, 10 children between ages 5 - 6, and 14 children between ages 9 - 10. The WNV turned out to be a useful test when some verbal communication was used in the test situation. This was especially apparent among the younger children, who needed extra verbal instructions and verbal support through the different subtests. The test also contained standardized verbal instructions for all ages.

Utvinning och analys av positionsdatafrån GPS-enheter : Jämförelse av metoder och program

In the field of IT-forensics you may often get to analyze different types of digital devices. One ofthese devices is the GPS navigation system. Nowadays GPS technology is getting more and morepopular and is included more frequently in different types of devices. With this article we want topresent the differenent obstacles and possibilites that a forensic investigator is presented with in thistype of investigation. We will be comparing different software suites and make use of forensic toolssuch as EnCase.The reader should get some understanding of the methods there are for analyzing one of these devicesand what problems that may occur in the investigation process.The article presents how the investigator can use different methods to gain information such as recentroutes, favourite destinations and other information that may be stored on the device.

Bring Your Own Device i kommun- och landstingsnätverk : En undersökning om dess utbredd

Något som har blivit en stor fråga på sistone där arbetsgivare tvingats ta ställning är huruvida anställda har tillåtelse att använda sina privata enheter på arbetet eller inte. Användandet av smarta telefoner och surfplattor i privatlivet har på bara några år ökat relativt drastiskt. I och med detta så har viljan också blivit större bland arbetare att kunna utnyttja sina privata enheter även i arbetslivet. Detta fenomen kallas för Bring Your Own Device och implementationen av detta kan orsaka vissa problem och kan exempelvis påverka nätverkssäkerheten. Arbetet ämnade, att genom en enkätundersökning, undersöka hur pass vanligt det var att man tillät privata enheter i arbetet bland Sveriges kommuner och landsting.

Design av motorstyrd lyfthjälp till toalettstol

The objective with this project was to design a new lifting aid connected to toilet chair.A questionnaire distributed at three homes for aged people indicated that there was an interest in a mechatronic lifting device.Since existing products have limited tilting functionality, the new design was chosen to introduce lifting by motorised tilting of the sitting platform. The mechanical construction was analyzed based on a maximum load caused by a person with weight 160 kg. Two linear actuators were used to control the tilting/lifting of the sit ?place, making standing-up easer.Finally, 28 persons tested the new lifting device and gave their impressions. Many appreciated the safe, stable lifting speed.

Svarar människor mer eller mindre socialt önskvärt beroende på hur de genomför ett personlighetstest?

A personality test is a useful tool in recruitment contexts. Studies have shown that participants distort their answers in a socially desirable manner. The purpose of this study was to investigate if people respond more or less socially desirable depending on how they rate themselves in a personality test, based on the "big five" personality dimensions.Eighty people, (40 women and 40 men), 19-42 years, (M= 24,1 SD= 3,76) rated themselves on a personality test. Group one, (20 women and 20 men) completed the test on paper. Group two, (20 women and 20 men) completed the test verbally.

Bring Your Own Device : Analys av trenden, dess möjligheter och problem

Syftet med denna studie är att få en grundläggande kunskap kring begreppet bring your own device. Eftersom ämnet är väldigt nytt och att det finns en viss okunnighet kring begreppet är det intressant att ta reda på varför BYOD är en uppgående trend, hur svenska verksamheter tänker inför tillåtandet, vilka krav som ställs och vilka problem som följer. För att komma fram till dessa slutsatser har intervjuer genomförts på tre olika verksamheter. Varav en verksamhet har tagit sig an BYOD och de andra två planerar inför tillåtandet av BYOD. Det har även genomförts intervjuer på både unga studenter, unga i arbetslivet samt en jurist för att få en tydligare bild av företeelsen.

Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.

Hur barn i årkurs 3 uppfattar syftet med Nationella provet

This is a study of the national test in 3rd grade. The national test is obligatory and is conducted in 5th and 9th grade, but since the spring of 2009 the tests also become mandatory in 3rd grade. The case study of this research is to find out how children in 3rd grade perceive the purpose of the national test. The survey should also clarify how students think and feel about the national test, and how they feel before the national test and after they have finished writing the test. Has the test positive or negative influence on children? The survey will also show how much teachers clarify what the significance of the national test is for the students.

Bring Your Own Device : Ur ett säkerhetsperspektiv

Syftet med denna studie är att identifiera hot, risker och konsekvenser kopplade till BYOD samt undersöka hur dessa kan lösas. BYOD är idag något som införs i allt större utsträckning hos olika företag världen över. Många är intresserade av alla möjligheter det kan frambringa, dock blundar allt för många för alla de olika hot och risker det samtidigt kan medföra. Utöver det tar vi i denna studie även upp hur man kan skriva en säkerhetspolicy kopplad till området BYOD. För att komma fram till våra slutsatser har vi förutom den teori vi samlat in fått hjälp av Jan-Olof Andersson en av Sveriges främsta IT-säkerhetsexperter med att skapa en riskanalys och en arkitekturbild.
