Wearable systems show considerable promise in monitoring and assessing the real-time performance of athletes, the health status of patients, or the general well-being of interested users. Most wearables today focus on monitoring physical parameters (e.g., activity, respiration rate, etc.), or electrophysiology (e.g., ECG, EEG, etc.). In order to augment the richness of collected data, the next-generation...
Consider N objects moving on a graph G = (V,E). Each item executes a random walk on the graph. Suppose at most k of the N objects are defective, and S sensors are placed at unique locations on G. At each time, each sensor provides a binary decision for the collection of objects in its graph neighborhood. A sensor returns 0 if no defective objects are present in its neighborhood and 1 if at least one...
An attractive electrochemical protocol for measuring ammonia based on carbon nanotube (CNT)/copper composite paste electrodes is described. The novelty of this work concerns the observed catalytic action of the CNT/Cu composite material, demonstrating the possibility to detect ammonia at a low potential (−0.120V versus Ag/AgCl) and at higher current values. These optimised composite electrodes showed...
