Benefits of Waveform Relaxation Method and Output Space Mapping for the Optimization of Multirate Systems [PDF]
, 2014 We present an optimization problem that requires to model a multirate system, composed of subsystems with different time constants. We use waveform relaxation method in order to simulate such a system.

Mattress-Based Non-Influencing Sleep Apnea Monitoring System
Sensors, 2023 A mattress-type non-influencing sleep apnea monitoring system was designed to detect sleep apnea-hypopnea syndrome (SAHS). The pressure signals generated during sleep on the mattress were collected, and ballistocardiogram (BCG) and respiratory signals ...

Broadband Waveform Modeling Over a Dense Seismic Network [PDF]
, 2006 We developed a "two-way" calibration technique for studying clustered events, particularly their mechanisms and rupture directivities. First, we demonstrate that the magnitude 4 events with known source mechanisms can be used to calibrate the path ...

Identify incipient faults through similarity comparison with waveform split-recognition framework
Frontiers in Energy Research, 2023 Introduction: Incipient faults of distribution networks, if not detected at an early stage, could evolve into permanent faults and result in significant economic losses. It is necessary to detect incipient faults to improve power grid security.

Predicting loss in magnetic steels under arbitrary induction waveform and with minor hysteresis loops [PDF]
, 2004 We have studied ways of predicting power losses in soft magnetic laminations for generic time dependence of the periodic magnetic polarization J(t). We found that, whatever the frequency and the induction waveform, the loss behavior can be quantitatively

Leida xuebao, 2023 Cognitive radar waveform design often relies on accurate clutter prior information. When prior information data is missing, the constructed clutter model will be severely mismatched, affecting the radar’s ability to suppress clutter.

Classification of sags according to their origin based on the waveform similarity [PDF]
2008 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America, 2008 A statistical method for classification of sags their origin downstream or upstream from the recording point is proposed in this work. The goal is to obtain a statistical model using the sag waveforms useful to characterise one type of sags and to discriminate them from the other type.
