Abstract A precise method for phase and amplitude detection in both the time frequency domains of terahertz spectroscopy based on weak-value amplification technique is proposed demonstrated. Within scheme, imaginary weak value enhances variations signals, whereas real amplifies changes signals. By employing various postselections measurement procedure detecting minute wave, we achieved a change range from −0.0187 rad to 0.0183 with an interval 0.004 −0.0238 0.0228 0.0056 rad. This results...

Various industrial and domestic applications call for optimized lightweight video LSTM network models on edge. The recent tensor-train method can transform space-time features into tensors, which be further decomposed low-rank analysis rank selection of tensor is however manually performed with no optimization. This paper formulates a search algorithm to automatically decide ranks consideration the trade-off between accuracy complexity. A fast method, called RankSearch, developed find...
Visual simultaneous localization and mapping (VSLAM) is one of the core technologies in autonomous driving, intelligent robots, metaverse other fields. Besides, loop closure detection (LCD) an essential component VSLAM which can correct drift accumulated errors caused by visual odometry (VO) front-end, assist robot to build a globally consistent map. Over years, several deep-learning methods have been proposed address task. However, prior neural network-based LCD models are heavy model size,...

Falling is ranked highly among the threats in elderly healthcare, which promotes development of automatic fall detection systems with extensive concern. With fast Internet Things (IoT) and Artificial Intelligence (AI), camera vision-based solutions have drawn much attention for single-frame prediction video understanding on by using Convolutional Neural Network (CNN) 3D-CNN, respectively. However, these methods hardly supervise intermediate features good accurate efficient performance edge...
Stratigraphic correlation based on well-logging data is able to help geological interpreters analogize and deduce underground sedimentary morphology. A great deal of traditional methods has been studied automatically or manually achieve stratigraphic correlation, the courses which are usually time-consuming not intuitive. Many uncertainties easily generated reduce effectiveness accuracy interpretation. To address this issue, paper introduces an interactive visual analytics system for...

In thin film solar cells, the semiconductor materials usually contain multiple impurity/defect states as donor or acceptor dopants. The local charge neutrality (LCN) condition determines equilibrium Fermi (EF) level and concentration of electrons holes. However, equation LCN is a transcendental EF.
