1. Enhancing Machine Failure Detection with Artificial Intelligence and sound Analysis
Sammanfattning : The detection of damage or abnormal behavior in machines is critical in industry, as it allows faulty components to be detected and repaired as early as possible, reducing downtime and minimizing operating and personnel costs. However, manual detection of machine fault sounds is economically inefficient and labor-intensive. LÄS MER
2. Failure diagnostics using support vector machine
Sammanfattning : Failure diagnostics is an important part of condition monitoring aiming to identify incipient failures in early stages. Accurate and efficient failure diagnostics can guarantee that the operator makes the correct maintenance decision, thereby reducing the maintenance costs and improving system availability. LÄS MER
3. Glory and failure : The difference engines of Johann Müller, Charles Babbage and Georg and Edvard Scheutz
Sammanfattning : This book presents a social and technical analysis of the first attempts to mechanize the production of numerical tablets. It deals with an age when the word "computer" denoted a human being and not a machine. LÄS MER
4. Synchronous Machines with High-Frequency Brushless Excitation for Vehicle Applications
Sammanfattning : Electrically excited synchronous machines (EESM) are becoming an alternative to permanent magnet synchronous machines (PMSM) in electric vehicle (EV) applications. This mainly attributes to the zero usage of rare-earth material as well as the capabilities of high starting torque and good field weakening provided by EESM. LÄS MER
5. Monitoring of wear in elasto- hydrodynamic lubricated contacts : Running-in and failure propagation
Sammanfattning : Elasto-hydrodynamic lubricated (EHL) contacts can be found in various machine elements or systems, like rolling element bearings, cam followers or gear transmissions. The service life of these elements and systems are depending to some extent on the performance of EHL contacts. LÄS MER
