Detektion av vätgasläckor med CUSUM-algoritmen

Detektion av gasläckor används i en mängd olika applikationer som till exempel kvalitetskontroll av kylskåp, lokalisering av skador på kablar och lokalisering av bränsleläckor i bränsletankar.Denna rapport undersöker förbättring av detektionsalgoritmen i en existerande vätgasdetektor.CUSUM algoritmen är en enkel men kraftfull metod för att snabbt detektera små ändringar i nivån av en Signal. Denna metod är anpassad till det dynamiska beteendet i sensorn som används för att spåra vätgasläckorna och även utvärderad på omfattande mätningar utförda på läckor med kända storlekar. Resultaten visar att användning av den föreslagna detektionsalgoritmen innebär en betydande ökning av detektorns prestanda. Särskilt bra blir resultatet på små läckor..

Inrapporteringsprocessen av förädlingskostnader för Scanias kalkylbilar

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the Signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed Signal the program should be able to show both the raw waveSignal and the processed measured data from the resonance peaks. Beyond the raw waveSignal and resonance peaks the program should also be able to control the automatic hammer.

Vibrationsbaserad maskinaktivitetssensor

I detta projekt undersöker vi om man kan bygga en maskinaktivitetssensor medhjälp av en enkretsdator som genom en accelerometer mäter en maskinsvibrationer. Sensorn skall generera en statusSignal. Accelerometern ger enmätbar Signal baserad på maskinens vibrationer. Enkretsdatorn används för attsampla, transformera och analysera Signalen och generera statusinformation.Med LabView kan vi spara, studera och analysera olika Signaler och olikatransformer. Vi studerar maskinvibrationer i LabView och beslutar att 5 kHzsampling räcker för att fånga intressanta vibrationer.

Indoor Positioning Using WLAN

This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..
