In this letter, we propose an indoor visible light positioning technique using a Modified Momentum Back-Propagation (MMBP) algorithm based on received signal strength (RSS) with sparse training data set.Unlike other neural network algorithms that require a large number of training data points to locate accurately, we have realized high-precision po
An optical sensor based on pyranine immobilized on aminopropyl-modified mesoporous silica films was developed for paraquat detection in aqueous solutions.An electrochemically assisted self-assembly method was used to deposit mesoporous silica film on fluorine-doped tin oxide glass.The obtained films were modified with various concentrations of 3-am
The detection technology of the microseismic source center of underground damage is mainly used for the location of the underground damage, positioning of explosion point of artillery shells in weapon testing ground.Aiming at the problem that clock error of microseismic acquisition sensor and the lack of high frequency information of acquisition da
Precise finite element modeling is critically important for the construction and maintenance of long-span suspension bridges.During the process of modeling, shape-finding and model calibration directly impact the accuracy and reliability.Scholars have provided numerous alternative proposals for the shape-finding of main cables in suspension bridges
A non-uniform distribution of diagnostic information in the electrocardiogram (ECG) has been commonly accepted and is the background to several compression, denoising and watermarking methods.Gaze tracking is a widely recognized method for identification of an observer’s preferences and interest areas.The statistics of experts’ scanpath
