The vibrational behaviour of misaligned rotating machinery is described and analysed in this paper. model, constructed based on the equations vehicle dynamics, considered dynamic excitation a single Hooke’s joint. system adopted breathing functions from recent publication to approximate actual mechanism cracked driveshaft. study aimed understand transmission nonlinear signal unbalanced drivesha...

Focal and non-focal Electroencephalogram (EEG) signals have proved to be effective techniques for identifying areas in the brain that are affected by epileptic seizures, known as epileptogenic zones. The detection of location focal EEG time seizure occurrence vital information help doctors treat seizures using a surgical method. This paper proposed computer-aided (CAD) system detecting classify...

Since the hydraulic axial piston pump is engine that drives transmission systems, it widely utilized in aerospace, marine equipment, civil engineering, and mechanical engineering. Operating safely dependably crucial, failure poses a major risk. Hydraulic malfunctions are characterized by internal concealment, challenging self-adaptive feature extraction, blatant timing of fault signals. By comp...

Time–frequency analysis is central to signal processing, with standard adaptation to higher dimensions for imaging applications, and beyond. However, although the theory, methods, and algorithms for stationary signals are well developed, mathematical analysis of non-stationary signals is almost nonexistent. For a real-valued signal defined on the time–domain R, a classical approach to compute i...
