Devices made from certain materials can double the frequency of light. Programmable electrodes can tune this response to produce various light spectra. In the field of electronics, reprogrammable ...

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 ...

In case you need reminder why you love cars, Peugeot just gave you one. A very sharp-edged, Tron-looking one. Teeny tiny at under 13 feet long, Peugeot says the Polygon is a drivable prototype built ...

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 ...

Abstract: To meet the requirements of high-precision measurement of time-frequency multiparameters, a high-accuracy frequency standard comparison technology combining adaptive frequency and Lissajous ...

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 ...

A new proposal to overhaul Polygon’s tokenomics is gaining momentum on the project’s governance forum and across social media, as investors voice frustration over POL’s steep underperformance compared ...

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 ...
