Abstract: Remote sensing image change detection refers to the automatic acquisition of the location and category of object changes using images of different phases. The rapid development of optical ...

Abstract: The frequency-domain curve fitting of dynamic system models in modal summation form is an essential process in mechatronics control, and it is widely used in various industries. However, as ...

Abstract: A novel frequency-dependent feeding network is proposed to feed an antenna array that works in an octave frequency range. To achieve a fixed beam direction in such a broad bandwidth, the ...

Abstract: Infrared images can provide prominent targets based on the radiation difference, making them suitable for use in all day and night conditions. On the other hand, visible images can offer ...

India's trading firms are shifting away from high-frequency options strategies after the country's regulator began a crackdown on the derivatives market. Top local speed traders are building ...

Abstract: A photonic-assisted microwave frequency measurement (MFM) method based on frequency-to-time mapping (FTTM) and frequency-to-power mapping (FTPM) is proposed and experimentally demonstrated.

Abstract: In the field of infrared small target detection (IRSTD), targets generally exhibit dim characteristics and are difficult to distinguish from background clutter. Learning-based methods ...

Abstract: The seismic data are usually limited by the frequency bandwidth and lack significant high-frequency components due to attenuation in the subsurface medium and frequency filtering effects ...

Abstract: In addition to the center-of-inertia (COI) frequency dynamics discussed in Part I, spatial frequency difference in power systems with grid-following (GFL) converters is also of critical ...

Abstract: This article introduces the electromagnetic frequency-difference autoproduct, the outer product of the harmonic electric field vector with itself at nearby frequencies, and describes its ...

Abstract: In the fields of microseismic monitoring and deep earth exploration, low-frequency signal detection faces problems, such as weak vibration signals, large ambient temperature changes, and ...
