Frequency-Adaptive Pan-Sharpening with Mixture of Experts [PDF]
arXivPan-sharpening involves reconstructing missing high-frequency information in multi-spectral images with low spatial resolution, using a higher-resolution panchromatic image as guidance. Although the inborn connection with frequency domain, existing pan-sharpening research has not almost investigated the potential solution upon frequency domain. To this

Antipodal Vivaldi Antenna for Water Pipe Sensor and Telemetry
International Journal of Geophysics, 2012 An antipodal Vivaldi antenna operates simultaneously for telemetry and sensing when placed conformally onto PVC pipes. Good radiation efficiency is realised and the antenna impedance matching remains stable when a pipe is empty or contains water.

Towards a Novel Perspective on Adversarial Examples Driven by Frequency [PDF]
arXivEnhancing our understanding of adversarial examples is crucial for the secure application of machine learning models in real-world scenarios. A prevalent method for analyzing adversarial examples is through a frequency-based approach. However, existing research indicates that attacks designed to exploit low-frequency or high-frequency information can ...

Frequency Domain TOF: Encoding Object Depth in Modulation Frequency [PDF]
arXiv, 2015 Time of flight cameras may emerge as the 3-D sensor of choice. Today, time of flight sensors use phase-based sampling, where the phase delay between emitted and received, high-frequency signals encodes distance. In this paper, we present a new time of flight architecture that relies only on frequency---we refer to this technique as frequency-domain ...

The Connection between the Quantum Frequency of Radiation and Frequencies of Circling of the Electron in Atom of Hydrogen [PDF]
arXiv, 2002 The connection between the quantum frequency of radiation by the transition of the electron from orbit n to orbit k and frequencies of circling of electron in these orbits for the atom of hydrogen is determined.

Micro frequency hopping spread spectrum modulation and encryption technology [PDF]
arXivBy combining traditional frequency hopping ideas with the concepts of subcarriers and sampling points in OFDM baseband systems, this paper proposes a frequency hopping technology within the baseband called micro frequency hopping. Based on the concept of micro frequency hopping, this paper proposes a micro frequency hopping spread spectrum modulation ...

Radiation behaviour of mm‐wave on‐wafer probes in H‐band and the influence on antenna measurements
Electronics LettersThis letter presents a comprehensive analysis of the radiation behaviour exhibited by nine distinct on‐wafer radio‐freqeuncy (RF) probes used for device characterization in the mm‐wave bands of integrated circuits and antennas.
