1. Adaptive Model-Based Temperature Monitoring for Electric Powertrains : Investigation and Comparative Analysis of Transfer Learning Approaches
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In recent years, deep learning has been widely used in industry to solve many complex problems such as condition monitoring and fault diagnosis. Powertrain condition monitoring is one of the most vital and complicated problems in the automation industry since the condition of the drive affects its health, performance, and reliability. LÄS MER
2. Supervised Failure Diagnosis of Clustered Logs from Microservice Tests
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Pinpointing the source of a software failure based on log files can be a time consuming process. Automated log analysis tools are meant to streamline such processes, and can be used for tasks like failure diagnosis. This thesis evaluates three supervised models for failure diagnosis of clustered log data. LÄS MER
3. Fault diagnosis of axlebox roller bearings of high speed rail vehicles based on empirical mode decomposition and machine learning
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Axlebox bearings are one of the most critical components of a rail vehicle with regard to safety. An axlebox bearing that breaks during operation can be dangerous for the passengers and expensive for the operator. In-service failure of axlebox bearings has been the cause of many catastrophic accidents. LÄS MER
4. Condition monitoring of induction machines using a signal injection technique
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. LÄS MER
5. Feldiagnostisering: sex läkares upplevelser
Kandidat-uppsats, Mälardalens högskola/Akademin för hälsa, vård och välfärdSammanfattning : Diagnosprocessen är en av de mest väsentliga delarna inom läkaryrket. En feldiagnostisering kan innebära förödande konsekvenser. Forskningen menar att några av orsakerna bakom feldiagnostisering kan bottna i kognitiv partiskhet och erfarenhet. LÄS MER
