With the rapid development of lithium-ion batteries, predicting battery life is critical to safe operation devices such as electric ships, vehicles, and energy storage systems. Given complexity internal aging mechanism their process exhibits prominent nonlinear characteristics. Knee point, a distinctive sign this process, plays crucial role in battery’s lifetime. In paper, cycle knee point are firstly predicted using time dimension space features early external characteristics battery,...

Wildfires have important effects on hydrothermal regimes of boreal permafrost. However, they are not yet systematically and extensively studied in Northeast China, except those discrete measurements during the early 1990s. Since 2017, a series study sites been built for continuous observation ground at ten three fire severity (unburned, light burn severe burn) areas (Mo’he, Alongshan Mangui) western flank northern Da Xing’anling Mountains, China. An integrated dataset was...

The plant protection unmanned aerial vehicle (UAV) scheduling model is of great significance to improve the operation income UAV teams and ensure quality operation. simulated annealing algorithm (SA) often used in optimization solution models, but SA has disadvantages easily falling into local optimum slow convergence speed. In addition, current research on for mainly oriented static scenarios. actual process, team faces unexpected situations, such as new orders changes transfer path costs....

Abstract Vitrimer is a new reprocessable thermosetting polymer based on the exchange of dynamic covalent bonds. However, vitrimer reported in literatures can usually be reprocessed at very high temperature, while relatively low temperature exhibits poor mechanical properties. It still great challenge to design mechanically robust with moderate reprocessing temperature. Herein, polyurethane‐urea elastomer including N , ′‐diaryl urea electron donating effect first reported, and it possesses...

Rapid and accurate detection of road cracks is great significance for health monitoring, but currently this work mainly completed through manual site surveys. Low-altitude UAV remote sensing can obtain images with centimeter or even subcentimeter ground resolution, which provides a new efficient economical approach rapid crack detection. Nevertheless, networks face challenges such as edge blurring misidentification due to the heterogeneity complexity background. To address these issues, we...

This paper studies LiFePO4 (LFP) battery capacity fading diversity among different cells with same type and specification under working states during their whole life cycle; consideration of this phenomenon, a novel state health (SOH) estimation method adaptability to is proposed. In order cope diversity, machine learning structure involving sparse auto-encoder (SAE) backward propagation neural network (BPNN) designed for SOH estimation. strategy, terminal voltage the later stage charging...

The development of wood derived cellulose nanocrystal (CNCs) based sustainable composites is potential to address the plastic pollution issue. However, because strong hydrogen bonding interactions inside CNCs, it still challenging obtain with satisfied comprehensive performance via incorporation CNCs into poly (vinyl alcohol) (PVA) matrix directly, so two strategies combined dopamine modification, base bath solution and ferric (III) ion treatment were reported tailor PVA/CNC composites....

Galloping of ice-coated transmission lines is occasionally observed under oblique wind directions. However, most current investigations on the galloping mechanisms are for flow perpendicular to span lines. In order address this gap, research studies characteristics flows based tunnel tests. The wind-induced displacement an aero-elastic iced-coated line model was measured with a noncontact measurement equipment in at different speeds and results show that characterized by elliptical...

In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may the neutral point potential on side shift. The shift will worsen control precision as well performance of unified power quality conditioner (UPQC), it also leads output voltage, even causing damage electric equipment. To deal with loads, paper proposes a matching-ratio compensation algorithm (MCA) for fundamental active component load currents, by employing MCA, balanced realized under...

In a recently accepted paper the authors have made an unfortunate omission. The purpose of this Letter is to address omission and acknowledge contribution [2], which was not included in list references [1], work [1].

With the implementation of regional coordinated development strategy, traffic flow has grown explosively. The construction a larger tunnel section becomes an effective way to solve highway network’s insufficient transport capability problem. Currently, there is little research on factors influencing and methods calculating loose pressure in surrounding rock mass for tunnels with super-large cross-sections. Based Bifurcation Tunnel, which one sign projects past five years, this paper...

In order to avoid the over-fitting in training of neural networks, we apply Bayesian learning networks. We illustrate advantages by concentrating on multilayer perceptrons (MLP) networks and markov chain monte carlo (MCMC) method for computing integrations. conduct experiments foreign exchange rate forecasting using approach. The experiment results show that is better at avoiding than traditional parameter optimization during phase

Magnetorheological (MR) technology has received tremendous attention, which is playing more and roles in modern industry. In order to give full play advantages of the MR devices, a good design great importance for high-performance device. This work introduces centrifugal effect (CE) plug flow region (PFR) into disc-type devices' obtaining higher accuracy. And, novel structure with trapezoidal cross section coil proposed devices improve magnetic field distribution. With this structure, damper...

On the basis of mathematical model DFIG's Grid-Side Converter(GSC) in two-phase stationary α-β reference frame, an improved control strategy GSC is presented based on sliding-mode (SMC). The method uses double-loop structure. Direct power used inner-loop, and a sliding mode controller was designed to improve dc-link voltage stability outer-loop. has advantages simple structure, high precision, rapid response speed strong robustness, which with both excellent transient steady state behavior...

In order to improve the properties of AC/DC converters, scholars in different countries have began apply nonlinear control theory based on storage function converters.
