Abstract: The constraints of traditional wavelet filters and wavelet coefficients such as it can not be based on the input signal changes, combined with underwater acoustic channel transmission and ...

Watermarking is identified as a major means to achieve copyright protection. It is technology of information hiding which is used to hide dedicated data in digital media like images, musics, videos ...

Mosquitoes have been responsible for the spread of several kinds of viruses among human populations for a long time. Recent mosquito-borne virus outbreaks, including dengue fever, chikungunya, and ...

Earth observation (EO) missions remain a challenging task for small satellite platforms due to their demanding requirements and space environment effects. In this study, the camera payload development ...

Rolling bearings are the most prone to failures in mechanical equipment, and the vibration signal is unstable. Therefore, according to this characteristic of the bearing, the time-frequency ...

Divisive normalization is a ubiquitous computation commonly thought to be an implementation of the efficient coding principle. Despite empirical evidence that it reduces statistical redundancy present ...

Presented here is a MATLAB-based program for image compression using discrete cosine transform technique. It works for both coloured and grayscale images. Over the last few years, messaging apps like ...

We report the honeybee’s propulsion at the air–water interface. Honeybees trapped on a water surface use their wings as hydrofoils, which means their wings generate hydrodynamic thrust. The surface ...

Oscillatory brain activity reflects different internal brain states including neurons’ excitatory state and synchrony among neurons. However, characterizing these states is complicated by the fact ...
