1. 1. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Johan Hansson; [2020]
   Nyckelord :Machine Learning; Vibrations;

   Sammanfattning : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. LÄS MER

3. 2. Locating Multiple Change-Points Using a Combination of Methods

   Master-uppsats, KTH/Matematisk statistik

   Författare :Johan Andersson; [2014]
   Nyckelord :;

   Sammanfattning : The aim of this study is to find a method that is able to locate multiple change-points in a time series with unknown properties. The methods that are investigated are the CUSUM and CUSUM of squares test, the CUSUM test with OLS residuals, the Mann-Whitney test and Quandt’s log likelihood ratio. LÄS MER

4. 3. Pressure Monitoring and Fault Detection of an Anti-g Protection System

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

   Författare :Kim Andersson; [2010]
   Nyckelord :EWMA; JAS 39 Gripen; Anti-g system; Fault detection; CUSUM;

   Sammanfattning : When flying a fighter aircraft such as the JAS 39 Gripen, the pilot is exposed to high g-loads. In order to prevent the draining of blood from the brain during this stress an anti-g protection system is used. The system consists of a pair of trousers, called the anti-g trousers, with inflatable bladders. LÄS MER

5. 4. Sensor Fusion for Enhanced Lane Departure Warning

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Erik Almgren; [2006]
   Nyckelord :CUSUM-test; Extended Kalman Filter; Kalman Filter; Lane Departure Waring;

   Sammanfattning : A lane departure warning system relying exclusively on a camera has several shortcomings and tends to be sensitive to, e.g., bad weather and abrupt manoeuvres. LÄS MER

7. 5. On Predicting Milk Yield and Detection of Ill Cows

   Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

   Författare :Nancy Grennstam; [2005]
   Nyckelord :;

   Sammanfattning : The fully automated milking system VMS has different functions which complements the actual milking of cows. This master thesis presents a method to improve the calculation of milk yield in dairy cows for the VMS. This report also investigates if it is possible to improve the algorithm for finding cows with mastitis (udder inflammation). LÄS MER
