Power load is the key to work of regional grid. The stability of the regional power grid will be improved if we can predict the power load in short term. So, this paper provides a new hybrid model to forecast electric power in short term based on generalized extremum learning machine (GELM) and Morlet wavelet neural net (WNN). Firstly, regarding power load probability as model output, this model will cut power load information into different parts according to frequency attributes using wavelet function, and then every part will be analyzed with similar scaler. Secondly, the WNN is trained quickly by the GELM. After randomly picking deviation between hidden layer and input coefficient, some output coefficient will be got by generalized inverse transformation of matrix. Then, after the displacement coefficient and scale coefficient of Morlet function being randomly selected, the hidden layer coefficients are gained with matrix inversion, and then the Morlet WNN is designed out. Finally, taking load data of some regional power grid as experimental data, the results show that the proposed model has high accuracy and reliability, which proves the high effectiveness of the algorithm.

In the spraying industry, the trajectory planning is the core part of industrial robots because model variety and shape of work-piece surfaces become the core problem of trajectory generation. In order to quickly plan the spraying trajectory and process of industrial robots, this paper proposes a trajectory generation model based on k-means mean clustering and a fitting optimization method based on NUrBS curve. The model obtains point cloud data, classifies and iterates the curvature according to the curvature threshold, and then plans the trajectory of each region according to the height and Angle of the spray gun in the spraying experience base to obtain the regional spraying trajectory points. The NUrBS curve is used to optimize the trajectory. In addition, on the basis of the above, a method based on infrared imaging target detection technology is proposed to quickly identify the acquired trajectory information and convert it to the coordinate system suitable for spraying robot operation.

The potential loss caused by defects is one of the most important factors affecting the performance of perovskite photovoltaic devices. CdS/ZnS quantum dots (Qds) have good hydrophobicity and can achieve the dual effects of waterproofing hydrophobic and defect passivation of perovskite films. The Lowest Unoccupied Molecular Orbital (LUMO) energy level of CdS/ZnS Qds doped perovskite film decreases from -3.75 eV to -3.85 eV. The barrier of photo-generated charge transport from the perovskite layer to the electron transport layer is significantly reduced, which is conducive to the enhancement of built-in potential. The density of trap states is reduced and the non-radiative recombination of carriers is suppressed. CdS/ZnS Qds doped perovskite film is dense and has a larger roughness, which helps to increase the contact area with the electron transport layer, thereby improving the charge transportation. Finally, the highest efficiency of the device with Qds reaches 21.42%, and the open-circuit voltage ( V oc ) and the short-circuit current density ( J sc ) are significantly increased compared with undoped ones. The hydrophobicity and stability of the device have also been improved. Therefore, the effect of CdS/ZnS Qds on passivation may provide new ideas for the efficient and stable perovskite solar cells. © 2022, The Authors. All rights reserved.

due to the close coupling between subsystems and complex energy flow, the distributed energy system is different from the traditional power grid in terms of optimal operation. Therefore, it is necessary to study the optimal operation strategy of distributed energy system. Optimization operation Strategy of a distributed energy station in Guangzhou, China was investigated. Ebsilon software was used to model and simulate the main components and auxiliary machines of distributed energy stations. The opening number and specific load of each main equipment in the distributed energy system were investigated under the cooling load demand of 1000~128000kW. According to the optimal operation scheme under different cooling load demand, the revenue of the energy station with peak-flat-valley electricity price were discussed. The results show that there is largest income while the chillers are operated in the generator supply mode and flat electricity price mode under high cooling load range; In the case of moderate cooling load demand, it is profitable to operate gas engine couple with lithium bromide chiller series centrifugal chiller, but it always causes a waste of energy because the supply of frozen water exceeds the demand; It is feasible to buying electricity to supply chiller for refrigeration operation under low cooling load range. This study provides an important reference for mastering the optimization operation strategy of distributed energy system with complex energy flow.

cost effective and complication-free wet chemical co precipitation protocal was employed to prepar Ni-Sn-layered double hydroxide and NiO/SnO 2 nanocomposites. Fundamental characterizations were done to evaluate structural, optical, morphological and dielectric behaviours. Cubic and tetragonal structures were witnessed for NiO and SnO 2 via Xrd analysis respectively. Allowed direct band gap nature was revealed from the optical absorption study and the calculated bandgap values were 3.29, 3.39, 3.09 and 3.20 eV for NiO. SnO 2 , NiO/SnO 2 , and Ni-Sn-LdH respectively. Surface features, stacked layered nanosheet arrangements and textural properties of the high-performance electrode materials were witnessed from SEM and HrTEM analyses. The composite materials, NiO/SnO 2 and Ni-Sn-LdH nanosheet, demonstrate an enhanced capacitance per unit area and superior capacitance retainable nature with numerical values of 821 F/g for 5mV/s scanning for NiO/SnO 2 sample. For 1 A per gram electric current density NiO/SnO 2 exhibited a capacitance of 99.2 % retentively beyond 300 consecutive cycles. High surface area and large active site densities of this electrode material enabled it to exhibit such performance with respect to charge storage, enhanced charge/discharge rates and long-term stability. The Ni-Sn-LdH electrode exhibited 315 F/g of capacitance per unit area at 5 mV/s scan rate. Appreciable retentive capacitance (98.01 %) and one ampere per gram beyond 300 cycles was shown by Ni-Sn LdH. Morphological dependent (granular structured layers) carbon-free stain less steel electrode supercapacitance properties were revealed from the present work.

Solar-thermal evaporation, a traditional steam generation method for solar desalination, has received numerous attentions in recent years due to the significant increase in efficiency by adopting interfacial evaporation. While most of the previous studies focus on improving the evaporation efficiency by materials innovation and system design, the underlying mechanisms of its energy efficiency are less explored, leading to many confusions and misunderstandings. Herein, we clarify these mechanisms with a detailed thermal analysis model. Using this model, we elucidate the advantages of interfacial evaporation over the traditional evaporation method. Furthermore, we clarify the role of tuning the solar flux and surface area on the evaporation efficiency. Moreover, we quantitatively prove that the influence of environmental conditions on evaporation efficiency could not be eliminated by subtracting the dark evaporation rate from evaporation rate under solar. We also find that interfacial evaporation in a solar still does not have the high overall solar desalination efficiency as expected, but further improvement is possible from the system design part. Our analysis gains insights to the thermal processes involved in interfacial solar evaporation and offers perspectives to the further development of interfacial solar desalination technology. copyright © 2021, The Authors.

Aiming at the problems of low efficiency, high cost, missing or wrong insertion of labor in PCB production, a method of electronic component location, grabbing and inserting based on machine vision is proposed. By building the machine vision system, three industrial cameras cooperate with dome light sources to take images of the whole components, the pin features of components and the jack features of PCB board respectively. After image acquisition, image processing is carried out on VisionPro 9.0 software platform, which mainly completes feature extraction of component pins and PCB board jacks, and coordinates positioning. Then, coordinate transformation is carried out by nine-point calibration method to guide the manipulator to complete the work of location, grabbing and inserting. Through the running test, the system has a fast grabbing speed and inserting speed. The error inserting rate, missing inserting rate, bad product rate and inserting precision all reach the standard, and the working efficiency is three times that of the manual.

Characterization of aqueous extract in traditional Chinese medicine(TCM) is challenging due to the poor retention of the analytes on conventional C18 columns. This study presents a systematic characterization method based on a rapid chromatographic separation(8 min) on a polar-modified C18(Waters cortecs T3) column of aqueous extract of cordyceps sinensis. UHPLC-HrMS method was used to profile components in both untargeted and targeted manners by full MS/PIL/dd-MS2 acquisition approach. The components were identified or tentatively identified by reference standards comparison, fragmentation rules elucidation and available databases search. A total of 91 components, including 10 nucleobases, 20 nucleosides, 39 dipeptides, 18 amino acids and derivatives and 4 other components, were characterized from the aqueous extract of C. sinensis. And this was the first time to systematically report the presence of nucleosides and dipeptides in C. sinensis, especially for modified nucleosides. The chemical basis inquiry of this work would be beneficial to mechanism exploration and quality control of C. sinensis and related products. Meanwhile, this work also provided an effective solution for characterization of aqueous extract in TCM.
