Abstract: Information about primary transmitter location is crucial in enabling several key capabilities in cognitive radio networks, including improved spatio-temporal sensing, intelligent ...

Global Positioning System (GPS) satellites have a wartime secret: they can suddenly boost their signal power to punch through ...

k‑means is a clustering algorithm that automatically groups similar data points together into K groups (clusters). K (like 3 or 4 clusters), and the algorithm finds K “centers” (centroids) such that ...

Abstract: Like k-means and Gaussian mixture model (GMM), fuzzy c-means (FCM) with soft partition has also become a popular clustering algorithm and still is extensively studied. However, these ...

Can an ESP32 detect people without cameras or motion sensors? Discover how Wi-Fi signal disturbances, CSI, and smart DSP enable real-time occupancy and mov ...

We designed our approach to be systematic and minimally biased by previous knowledge of yeast biology. Our objective was to discover distinct expression patterns (clusters) in mRNA data sets and then ...
