This paper presents a fully distributed reactive power optimization algorithm that can obtain the global optimum solution of nonconvex problems for distribution networks (DNs) without requiring central coordinator. Second-order conic relaxation is used to achieve exact convexification. A second-order cone programming solver (D-SOCP) formulated corresponding given division areas based on alternating direction method multipliers (ADMM) algorithm, which greatly simplified by exploiting...
Main observation and conclusion With the rapid development of wearable electronics, flexible supercapacitor with high energy density has attracted more attentions. From viewpoint outdoor underwater application, this research tried to impart superhydrophobicity supercapacitors. The polyvinyl alcohol/HNO 3 hydrogel was utilized as electrolyte, which could achieve self‐healing capability without freezing/thawing process. Both microscale graphene nanoscale carbon nanotubes were electrode...

In vitro in vivo antitumor efficiency of evaluated on CRC cells mice xenograft.Results The results showed that HT-29 uptake C over 70%. Reactive oxygen species (ROS) sensitive formulation improved...
Distributed generators can be integrated in geographically distributed areas and microgrids of active distribution networks (ADNs), operate independently. On the basis alternating direction method multipliers, authors describe an efficient fully algorithm to solve multi-area economic dispatch problems ADNs without requiring a central coordinator. The physical interpretation proof for its convergence are both given. Network losses taken into account by exploiting features ADNs. Two other...
Predicting the remaining useful life (RUL) of critical subassemblies can provide an advanced maintenance strategy for wind turbines installed in remote regions. This paper proposes a novel prognostic approach to predict RUL bearings turbine gearbox. An artificial neural network (NN) is used train data-driven models and short-term tendencies feature series. By combining predicted training features, polynomial curve reflecting long-term degradation process fitted. Through solving intersection...
Optical logic gates call for materials with giant optical nonlinearity to break the current performance bottleneck. Metal–organic frameworks (MOFs) provide an intriguing route achieve superior benefitting from structural diversity and design flexibility. However, potential of MOFs optoelectronics has been largely overlooked their applications in have not exploited. Here, through temporally manipulating nonlinear absorption process porphyrin-based MOFs, we successfully developed AND XOR...
Incipient fault detection of wind turbines is beneficial for making maintenance strategy and avoiding catastrophic result in a farm. A deep neural network (DNN)‐based approach proposed to deal with the challenging task direct drive turbine, involving four steps: preprocessing method considering operational mechanism presented get rid outliers supervisory control data acquisition (SCADA); conventional random forest used evaluate importance variables related target variable; historical healthy...
Transmission towers are structurally complex, which makes it challenging to choose the right place and number of sensors for health monitoring. In this paper, optimal sensor placement a cat-head-type transmission tower is conducted by using Effective Independent Method (EIM) method proposed calculating minimum structural monitoring combining EIM Modal Assurance Criterion (MAC). The prescribed in paper derives curve that shows relationship between MAC value sensors. It found decreases with...
Alkaline phosphatase (ALP) is widely present in the human body and an important biomarker. Numerous ALP detection studies have been carried out, ascorbic acid (AA) often used as reducing component sensors to monitor levels since it can be produced from 2-phosphate (AA2P) hydrolysis presence of ALP. However, well-known that AA a strong agent easily oxidized. The disproportion between oxidized reduced reactions results generation free radicals with single electrons may lead inaccurate assays....
The conventional method of detecting a gear fault is to demodulate the vibration signal collected from gearbox based on Hilbert transform; however, this requires human intervention and lacks sophistication. Empirical mode decomposition (EMD) significant timefrequency tool for adaptively decomposing signals into collection intrinsic functions (IMFs); feature can be extracted one IMFs reveal location level or bearing in mechanical drive system. In paper, multi-harmonic model with modulation...
