Well-aligned ZnO/ZnSe core/shell nanowire arrays with type-II energy alignment are synthesized via a two-step chemical vapor deposition method. Morphology and structure studies reveal transition layer of wurtzite ZnSe between the ZnO core cubic shell. Type-II interfacial transitions observed in spectral region from visible to near infrared transmission photoluminescence. More significantly, for first time, is shown extend photoresponse prototype photovoltaic device based on coaxial array...
We report the development of complete structural AlGaN-based deep-ultraviolet light-emitting diodes with an aluminum thin layer for increasing light extraction efficiency. A 217% enhancement in peak photoluminescence intensity at 294 nm is observed. Cathodoluminescence measurement demonstrates that internal quantum efficiency deep-UV LEDs coated Al not enhanced. The emission attributed to higher LEE by surface plasmon-transverse magnetic wave coupling. When proportion TM increases content...
Predicting students’ performance is very important in matters related to higher education as well with regard deep learning and its relationship educational data. Prediction of provides support selecting courses designing appropriate future study plans for students. In addition predicting the students, it helps teachers managers monitor students order provide them integrate training programs obtain best results. One benefits student’s prediction that reduces official warning signs expelling...
Vital sign monitoring plays a critical role in tracking the physiological state of people and enabling various health-related applications (e.g., recommending change lifestyle, examining risk diseases). Traditional approaches rely on hospitalization or body-attached instruments, which are costly intrusive. Therefore, researchers have been exploring contact-less vital with radio frequency signals recent years. Early studies continuous wave radars/WiFi devices work detecting signs single...
In order to improve the performance of AlGaN-based deep ultraviolet light-emitting diodes (UV LEDs), optical and physical properties UV LEDs with a p-type thickened last quantum barrier (LQB) are studied numerically.

Smoothed Particle Hydrodynamics (SPH) method is used to solve water hammer equations for pipeline systems due its potential advantages of easily capturing column separation and slug impact. Currently, the SPH-based model has been only developed simulate single pipe flow with simple boundary conditions. It still a challenge apply practical distribution (WDSs). To address this issue, study develops complete Water Hammer Distribution System (SPH-WHWDS). Within proposed method, complex internal...
We report localised-surface-plasmon (LSP) enhanced deep-ultraviolet light-emitting diodes (deep-UV LEDs) using Al nanoparticles for LSP coupling. Polygonal were fabricated on the top surfaces of deep-UV LEDs oblique-angle deposition method. Both top- and bottom-emission electroluminescence with 279 nm multiple-quantum-well emissions can be effectively by coupling generated in nanoparticles. The primary wavelength is longer than top-emission wavelength. This difference attributed to...
The leakage control in water distribution networks (WDNs) is of high concern the supply industry. One direct and effective way to reduce adopt detection localization methods guide utilities repair broken pipes time. In order achieve higher accuracy process WDN with multiple leaks, a novel leak framework (MLDLF) based on existing pressure flow measurements proposed. MLDLF decomposed problem into three substages: model calibration, identification, localization. After using calibrated hydraulic...
To address the problems that most convolutional neural network-based image defogging algorithm models capture incomplete global feature information and defogging, this paper proposes an end-to-end network vision transformer hybrid algorithm. First, shallow features of haze were extracted by a preprocessing module. Then, symmetric structure including (CNN) branch was used to local image, respectively. The mixed fused using layers cover representation while retaining features. Finally,...

Recognizing the low-cost advantage of phased arrays, we investigate improvement beamforming capability a array via use double-phase shifters (DPS), i.e., each antenna is fed with sum outputs two phase shifters. The DPS allows for manipulation both magnitude and signal transmitted by antenna, thus enabling formation flexible beam toward desired target while suppressing energy radiated unwanted directions. By sequentially steering mainbeam to target, nulling other targets, one can monitor...
