Complex feature analysis of center of pressure signal for age-related subject classification
Purpose: The aim of this study was to characterize prolonged standing and its effect on postural control in elderly individuals in comparison to adults.Materials and Methods: The elderly individuals’ behavior during standing and how demanding such a task is for them, is still unknown. We recorded the center of pressure (COP) position of 12 elder and 15 young participants while they were standin...
متن کاملHarmonic analysis and restoration of separation methods for periodic signal mixtures: Algebraic separation versus comb filtering
The problem of separating a mixture of periodic signals into its constituent components occurs in sound detection, biomedical signal processing, and in communications. Existing approaches to solving it are either based on harmonic selection in the frequency domain or on linear comb filtering in the time-domain. In this paper, the recently proposed matrix algebraic separation approach is analyze...
متن کاملA Novel Frequency Domain Linearly Constrained Minimum Variance Filter for Speech Enhancement
A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...
متن کاملتغییرات مؤلفه های فرکانسی و زمانی الکترورتینوگرام در بیماران مبتلا به رتینیت پیگمنتوزا در مقایسه با افراد سالم
Background and purpose: Retinitis Pigmentosa (RP) is one of the retinal degeneration diseases affecting the eye signals. Electroretinogram (ERG) is a signal that plays an important role in diagnosis and treatment of RP. This signal includes useful information that cannot be revealed just in time domain. We aimed to investigate the effect of RP on time, frequency, and time-frequency parameters o...
متن کاملOutput-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data
The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...
