Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.

This master?s thesis presents experiences from an evaluation of AdApt, a multi- modal, conversational dialogue system, using PARADISE, PARAdigm for Dialogue System Evaluation, a general framework for evaluation. The purpose of this master?s thesis was to assess PARADISE as an evaluation tool for such a system. An experimental study with 26 subjects was performed.

Syftet med detta examensarbete var att jämföra olika system för att lagra spannmål på.Spannmål som skall blandas in i fodret till de värphöns som finns på gården där det system som jag finner är bäst skall sättas upp. Jämförelsen gäller dels helt olika system, silo tork kontra lufttät lagring och olika systeminom lufttät lagring. Jämförelsen har varit en mestadels ekonomisk jämförelse men jag har även gjort en liten teknisk jämförelse. För att få fram fakta som jag kunde basera min fallstudie på så jämförde jag fyra olika system mot varandra.Det som jämfördes var els två system med lufttät lagring, ett system med silo torkning och ett system med inköpt färdigtorkad spannmål. Jag gjorde olika investeringskalkyleroch fick fram den totala årskostnaden för varje system och dels kostnaden per kilo spannmål för varje system samt också vad foderkostnaderna blir.

Många rekryteringsmetoder som används i dag, som CV och referenstagning, har enligt studier låg validitet, däremot visar många studier att personlighet är stabilt över tid och därför är en mer valid prediktor för att kunna predicera arbetsprestation. Studiens syfte var att undersöka Shapes, ett internetbaserat personlighetstest, och dess arton kompetensdimensioner med test-retest utifrån tre frågeställningar. En datainsamling med 91 deltagare (29 män och 62 kvinnor) gjordes vid två tillfällen med tre veckors mellanrum. Deltagarna delades upp i kön- och åldersgrupper för att se skillnad över tid inom grupperna. Medelvärdesskillnader och korrelationer över tid jämfördes där resultatet visade att det fanns positiva samband mellan båda testtillfällena på samtliga dimensioner.

This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.

Sammanfattning:De ökande testdatavolymerna som krävs för att testa moderna System-On-Chip (SOC) bidrar i hög grad till den ökande produktionskostnaden. De stora testdatavolymerna kräver stora och dyra Automatic Test Equipment-minnen (ATE-minnen). För att minska behovet av dessa minnen så har olika komprimeringsmetoder utvecklats.Denna rapport beskriver arbetet med att implementera en given komprimeringsmetod för testdata till SOC. Den metod som används heter vector repeat och den implementeras genom skapandet av ett för ändamålet avsett dataprogrogram. För att vector repeat ska fungera effektivt så förutsätts det att in- och utgångarna på den ATE som används kan delas in i olika portar.

The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.

This study where designed to investigate if there are any positive relationship between the extent of physical activity during adolescent's leisure time and the academic performance, and also if there are any negative relationship between the academic performance and the time spent in front of the television or computers. Another part of the study tried to find out if physical activity has a direct and immediate influence on the performance in school. 91 pupils (51 girls and 40 boys) in the 8:th year of the Swedish primary school, from three different schools participated in the study. All 91 pupils first responded to a questionnaire concerning there activities in leisure time. They where then tested in a mathematical test and the results where compared with the extent of physical activity and TV/computer time they had stated in the questionnaire.

Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

Lansen Technology is a security company from Halmstad, Sweden and their focus indeveloping and selling alarm solutions. One of their latest inventions is a vibration sensor thatrecognizes very small movements in the ground.The thesis work was made in cooperation with Lansen Technology AB and the task was toinvent a test equipment that decides whether the sensor is working correctly. By generatingcertain frequencies with specific amplitude, we will expect the sensor to give a similar output.The final report includes all the parts of our work as studying, choosing components,programming, construction, results and conclusion..

The signal strength(RSSI) has been read in the configuration menu of the broadband routers as well as in the cellphone.The conclussions drawn:Net1s net appears to be more used compared to its capacity than the other netsTele2s net has a high and even data rate where it?s signal strength is sufficient.

An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.
