We observed the phase transition of multiple superradiant states in chaotic optical cavities with multiple open decay channels base on photonic crystals.
By combining analytic theory, parallel ab-initio simulations and experiments, we demonstrate how to exploit chaos to dramatically enhance light trapping performance.
The wavelength limit (λc) of detection in a conventional photodetector is limited to a characteristic energy (Δ) through the relationship: λc = hc/Δ, where Δ also determines the detector noise (dark current) and hence its performance such as the operating temperature. Here, we report an infrared photodetector with an extended operating range (responding beyond the standard spectral threshold) based...
Ion exchange is used to remove tetramethylammonium hydroxide from an aqueous solution. Both strong acid cation (SAC) and weak acid cation (WAC) exchange resins show excellent uptake of the ion. The pseudo-second-order kinetic model fits the data of uptake rate well. When using an SAC exchange resin, the pH does not affect the uptake efficiency, while that of the WAC exchange resin is...
Configuration is an effective way to improve reliability and survival ability of power system. A Single Memory Agent Search (SMAS) algorithm was developed to solve reconfiguration problem of Electric Propulsion Ship (EPS) integrated power system when faults occurred. The algorithm imitated the process of information coding, information storing and information retrieving in human brains to configure...
This study uses data envelopment analysis and Bayesian networks in e-learning systems evaluation and classification, respectively. By maximizing the weighted summed-outputs-to-weighted-summed-inputs ratio, we obtain the scores of individual as well as groups of reviewers from relative efficiency perspectives. The efficiencies are used as training data to construct the classification model for further...
