Weak Signal Detection and Fault Diagnosis

Dear Colleagues,

When the working status of various equipment is abnormal, this is often first discovered by detecting weak signals. It is of the utmost importance to accurately detect the characteristics of weak signals, identify them, and confirm whether these weak abnormal signals are faults through intelligent diagnostic methods. Although research in this field began many years ago, research using artificial intelligence technology has only been ongoing for a decade or so. The intelligent diagnosis of these faint abnormal signals, which are often hard to see, time-varying, nonlinear, extremely weak, and have low recognition accuracy due to environmental factors, is quite significant. Of course, finding dynamic cross domain diagnostic patterns is an important research method. There are also some weak fault diagnosis studies that integrate model-driven and data-driven approaches, which are important research directions in fault diagnosis. We look forward to receiving papers on the research achievements of our peers in this field for different operating equipment.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Machines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
