Solution-processed hybrid perovskite of CH3NH3PbI3 (MAPbI3) exhibits an abnormal luminescence behavior at around the tetragonal-orthorhombic phase transition temperature. The combination time resolved photoluminescence (PL), variable excitation power PL, and variable-temperature X-ray diffraction (XRD) allows us to clearly interpret features in region MAPbI3. Both PL XRD results unambiguously prove coexistence tetragonal orthorhombic phases MAPbI3 temperature range 150 130 K. two observed T...
In this report, alumina–silica composite ceramic is manufactured by using the 3D–Direct Ink Writing (DIW) printing technology based on additive manufacturing. order to improve compactness and mechanical properties of alumina ceramics, silica submicron-particles are introduced as sintering aids fillers. However, no research has focused effect adding 3D–DIW. Due addition submicron-particles, upper limit solids in 3D–DIW ink increased. Then rheological behavior was studied. linear viscoelastic...
Distributed acoustic sensing (DAS) is an emerging technology that has gained significance in various domains, including geophysics and security, due to its unique characteristics of long-distance capability, massive points, large bandwidth. DAS based on coherent detection been heavily studied recent years, advantages over direct-detection scheme. However, usually generates a significant volume data, since probe signals with wider bandwidth generally have better performance, which presents...
Phase-sensitive optical time-domain reflectometry (Φ-OTDR) has revolutionized geophysical research by providing a method for large-scale distributed acoustic sensing (DAS), especially with the assistance of artificial intelligence (AI). However, demodulation and AI-based denoising are separate processes, ultimately impacting unified integration signal processing. Here, we developed an integrated Demodulation Denoising (2D) SenseNet, supervised deep learning network designed to sense state...
Seismic exploration demands high temporal-spatial resolution and cost-effective deployment. Distributed acoustic sensing (DAS), an emerging seismic exploring technology utilizing optic-fiber cables, supports intensified real-time observation of geological activities. Phase unwrapping, a critical step in deriving disturbance from DAS raw data, traditionally relies on phase continuity, assuming the original difference between adjacent measurements is less than <inline-formula...
Abstract Spin glass theory, as a paradigm for describing disordered magnetic systems, constitutes prominent subject of study within statistical physics. Replica symmetry breaking (RSB), one the pivotal concepts understanding spin means that under identical conditions, systems can yield distinct states with nontrivial correlations. Random fiber laser (RFL) based on Rayleigh scattering (RS) is complex system, owing to disorder and stochasticity RS. In this work, first time, precise theoretical...
This paper presents direct methods for vision-based control the application of industrial inkjet printing. In this, visual is designed with a coupling between camera measurements and joint motion. Traditional servoing commonly has slow update rate needs an additional local controller to guarantee stability. By only using product as reference sampling high rate, are sufficient controlled positioning. The proposed method simpler more reliable than standard motor encoders, despite tight...
This article is a study of the scattering sound by fish in forward direction. It shown that contrast to situation with backscattering, body rather than swimbladder primarily responsible for forward-scattering at high frequencies. In addition, function has simple structure compared backscattered signal. Since shape relatively easy obtain, models which major target are expected be superior those based on swimbladder. More experimental work forward-scatter would seem worth while. Comparisons...

For future augmented reality (AR) and virtual (VR) applications, several different kinds of sensors will be used. These sensors, to give some examples, are used for gesture recognition, head pose tracking pupil tracking. All these send data a host platform, where the must processed in real-time. This requires high processing power which leads higher energy consumption. To lower consumption, optimizations image system necessary. paper investigates detection AR/VR applications based on images...
Seismic monitoring requires high temporal-spatial resolution and low deployment cost. Distributed acoustic sensing (DAS), as an emerging technology for recording seismic data in recent years, can leverage communication cables monitoring, providing strong support more intensive real-time observation of geological activity. However, the traditional DAS phase unwrapping algorithms (PUAs) derived from Itoh difference adjacent pixels to be less than &#960;, thus make mistakes case severe...
A deep learning model was proposed to simultaneously integrate the functions of demodulation and denoising for phase-sensitive optical time domain reflectometry ( <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\Phi$</tex> -OTDR), resulting in low-noise reconstruction phase curves.
We introduce a 2-D phase unwrapping algorithm to DAS, surpassing dynamic range limits of conventional methods. Considering inter-trace phases, it enhances unwrap ability, mitigating stripe error caused by low SNR.
Mid-infrared spectrum is a critical tool for chemical analysis, industrial inspection, environment, and other fields due to its rich bond information. However, the complicated growth or fabrication procedures of existing mid-infrared sensitive materials hinder large-scale production utilization detectors. To address this issue, we developed Si:S barrier detectors employing sulfur doped silicon sophisticated band design. Since transport dark current photo separated, design effectively...
A significant $\phi$-meson global spin alignment ($\rho_{00}$) signal was measured in Au+Au collisions at $\sqrt{s_{NN}}\le62$ GeV. Conventional physics mechanisms such as $s(\bar{s})$ polarization fail to accommodate this $\rho_{00}$ signal, motivating further investigation into its origin. Recent studies from a general framework utilizing the gauge/gravity duality predict that there could be non-zero helicity-frame generated by relative motion of $s\bar{s}$ pairs thermal background...
Visual servoing, which applies computer vision as a feedback source for control, is becoming cost effective solution high performance mechatronic systems. However, the potential of visual servoing systems limited by current design methodology, explores cyber domain and physical separately. We propose to use cyber-physical system approach overcome such limitation.
High-speed visual servo systems are used in an increasing number of applications. Yet modeling and optimizing these remains a research challenge, largely because consist tightly-coupled design parameters across multiple domains, including image sensors, vision algorithms, processing systems, mechanical control among others. To overcome such this work applies axiomatic method to the high-speed that cross-domain couplings explicitly modeled subsequently eliminated when possible. More...
Machine vision systems (MVS) use image sensors to process and analyze data. Depending on the application, sensor parameters are configured differently. However, some fixed for a specific product generation or line. One of these is pixel pitch, distance from one physical another.
