Instantaneous FrequencyEnsemble Empirical Mode Decomposition (EEMD)To investigate the value of decomposed short-time digital volume pulse (DVP) signals in discerning systemic vascular anomaly in diabetic patient
IMFn(t) must also be a monocomponent function. Eq. (13) allows the amplitude and the instantaneous frequency to be presented in a 3-D plot, in which the amplitude is represented by the height in the time–frequency plane. This time–frequency distribution...
Because of the wide variation in battery lifetime depending on the charging frequency and pattern of use, battery maintenance tools are indispensable. The 3555 BATTERY HiTESTER provides a simple, on-the-spot assessment of the state of compact storage batteries, including nicad (Ni-Cd) and nickel...
WPD has multi-scale characteristics and provides great choice for time–frequency analysis. In the multires- olution wavelet analysis, the Hilbert space L2ðRÞ is decomposed into the sum of all orthogonal wavelet sub- spaces Wjðscale factor j 2 ZÞ: L2ðRÞ ¼ È Wj j2Z ...
INSTANTANEOUS-ACTION CALENDAR DEVICEAbstract of the Disclosure The herein-proposed instantaneous-action calendar device is made use of in small-size wrist watches and comprises a stationary fixed component, a date ring, a day indicator, a rotary actuator, an accumulator and jumpers. The rotary actua...
We were unable to apply a recent model for mechanical flight based on pigeon flight [82] because of transient effects associated with vari- ation in wing beat frequency. Results Ground speed and wing beat frequency Ground speed decreased with the magnitude of the component of wind speed against...
Traffic conflicts are used to investigate road users’ behavior in safety–critical situations at certain road entities, and the safety level of the investigated behavior and road entities are evaluated by traffic conflict frequency and/or severity. Such applications are abundant and widespread among di...
