In this article, a technique for cooperative spectrum sensing (CSS) using the Extreme
Learning Machine (ELM) is proposed. ELMs are feedforward neural networks where the …

Spectrum is one of the world's most highly regulated and limited natural resources.
Cognitive Radio (CR) is a cutting‐edge technology that aims to solve the future spectrum …

Abstract Background Human milk oligosaccharides (HMOs) are important components of
breast milk and may be responsible for some of the benefits of breastfeeding, including …

Background Human milk oligosaccharides (HMO) function as a prebiotic, enhance immune
functions, and support brain development for infants when fed mother's milk. These are …

Aiming at the problem of spectrum monitoring of low-power wideband signals in complex
electromagnetic environments, this paper proposes a double threshold weak signal detector …

The radio spectrum is one of the world's most highly regulated and limited natural resources.
The number of wireless devices has increased dramatically in recent years, resulting in a …

Bolt connections are subjected to severe service conditions, such as cyclic loading and
mechanical shock, leading to loosening failure. Commonly, the degradation of the bolt …

The degradation of the pretightening state of bolts is a multistage process. Utilising a single
model to monitor the pretightening state in the full degradation stage and continuously …

In this paper, a method for identifying the tight contact stage and quantitative monitoring of
the pre-tightening state to bolt loosening in TCS based on nonlinear Lamb waves is …
