We show that the knowledge of time dependent response a trapped gas, subject to sudden rotation confining harmonic potential, allows for determination moment inertia dipolar supersolid configurations. While in presence one-dimensional arrays droplets frequency resulting scissors oscillation provides accurate access value inertia, two-dimensional like configurations are characterized by multi-fr...

This study focuses on the performance validation of a wave energy converter (WEC) equipped with resonant frequency adjustment capability. Achieving resonance oscillation period waves is crucial for maximizing efficiency conversion systems. For this purpose, we introduce variable moment inertia (VMI) device that allows tuning by adjusting position mass. proposed approach, verification experiment...

A method for fingerprint matching using invariant moment featuresis proposed. The fingerprint image is first preprocessed to enhance the original image by the Short Time Fourier Transform (STFT) analysis. Then, a set of seven invariant moment features is extracted to represent the fingerprint image from a cirque of Interest (COI) based on the reference point of the enhanced fingerprint image. T...

In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...

Introduction Many features, emerging from mathematical techniques, have been used in the analysis of brain signals. In this study, the physical quantity of “moment of inertia” (MOI) was introduced as a feature to enhance high-frequency waves (HFWs) in electroencephalography (EEG). Materials and Methods In this research, the recorded EEGs from F3, F4, and Cz points in 20 males were used. A total...
