The joint operation of multiple UAVs complies with the effectiveness and efficiency arrangements. However, in the case of joint flight and operation of multiple UAVs, GOS becomes important, which is also the important core of this research. This study mainly applies the combined optimization of hyperbolic partial differential equations through the mathematical wave vibration model to achieve the GOS of multi-unit UAV collaborative power grids and towers detection and cleaning system. This study analyzed the flight position convergence, and found that the OCS of multi-unit UAV collaborative power grids and towers detection and cleaning system in this study is more capable of controlling the flight position than the previous method, and the data is similar to 90 m. Also, the time delay error is also compared. The result can also be seen that the OCS of this study is better than the traditional method by about 0.2 under the same iteration steps. To sum up the foregoing, This study believes that the OCS of multi-unit UAV collaborative power grids and towers detection and cleaning system in this study has better tracking and matching capabilities of position and flight speed of UAV, with less delay error and better convergence, so it can provide The robustness and reliability of OCS that meet our needs.

For years, the study on human-computer interaction in the mixed reality has been exploring in more natural and efficient interacting ways. As a common interacting component, the traditional menu on tangible user interface is not well suited to virtual interactive scenes in mixed reality and virtual menu represents a new category of efficient interacting methods in mixed reality. Recently, the combination of gesture recognition with the virtual menu has attracted little attention from researchers. To implement a natural, intuitive, and efficient interaction, in this work, a virtual menu using gesture recognition is proposed for the 3D object manipulation in mixed reality. In particular, several gesture states with respect to the different stages of menu interaction are first defined; then, the gestures on the screen are mapped to 3D virtual objects through coordinate transformation; and finally, the style and interaction logic of the menu is introduced to. In the experiment, the user’s interaction results using different menus are evaluated by comparing the time needed and the result’s accuracy with the same tasks. The experimental results show that our proposal can effectively reduce the number of interacting operations, and improve the efficiency of interacting process.
There are incredibly renewable outlets such as solar and wind intermittent, and machine reliability is hard to sustain with the intolerable balance of green energy resources. Because of population growth and technological development, global energy demand is increasing exponentially. However, civilization must address a stable energy source for two benefits, a cost-effective and sustainable basis for future renewable energy production. Solar Energy is a platform for green energy and is a potential means of solving problems that face a possible energy system. The power output is primarily determined by the properties of the incoming radiation and solar panels. Precise and accurate knowledge of these variables provides a consistent model for predicting the solar future. Solar power forecasts would have a significant effect on the viability of massive solar energy projects. This study presents a new approach to predict the expected amount of energy to be produced from Photovoltaics using a hybrid deep neural network based on a combination of extended short-term memory networks (LSTM) and convolutional neural networks (CNN), taking into account the energy of electrons and photons as well as elements and climatic conditions as input data.
With an improved algorithm based on the Otsu method, this paper proposes solving the shadow region problem caused by non-uniform illumination. The recent image processing algorithms for handling the shaded area's issue for the massive difference in the image grey value will not be practical. It is not easy to directly set the shaded area's content to "black" based on this problem. This paper proposes improved threshold image segmentation for Non-uniform illumination based on the Otsu optimization Approach. It uses the local area threshold and window image pixel by sliding to enhance the image recognition rate of a shaded area. Experimental results verify that the proposed segmentation method has more robust adaptability to images with shadows. Compared with the classical global OTSU algorithm and genetic algorithm optimization, the image recognition rate is 96%.
Smart meters are the basic equipment for data collection in a smart grid system and responsible for collecting, measuring, and transmitting original electricity data. The smart meter data is first transmitted to the data aggregation point (DAP) through wireless communication and then transmitted to the control center. Each DAP installation incurs costs, but the number and locations of DAPs have an impact on the quality of communication services due to the distance between DAP and smart meters and the related transmission routes. Therefore, it is important to choose the best positions for installing DAPs in a smart meter network. This study investigates the DAP placement problem and proposes a solution to reduce the number of DAPs and the distance between DAPs and smart meters by using a grid-based model. Without loss of generality, simulations for performance evaluation are conducted based on random data. The simulation results show that the proposed solution can reduce the number of DAPs in a smart meter network.
Ontology matching can solve the heterogeneity problem between two ontologies, and EA represents a state-of-the-art technique for matching ontologies. However, there are two defects concerning the EA-based ontology matching technique: (1) a reference alignment between two ontologies to be matched is required in advance; (2) the confidence of entity similarity measure is low computational complexity of measuring the similarity value is high. To overcome these drawbacks, in this paper, an Evolutionary Algorithm with Context-based Reasoning method (EA-CR) is proposed, where: (1) an approximate metric without the reference alignment is utilized for evaluating the alignment’s quality; (2) a Context-based Reasoning method is presented to distinguish the heterogeneous entities. The experimental results show that the proposed approach is effective.
Parallel processing is an effective measure of inefficient and effective computations of function optimization. Now we propose a new communication strategy for the parallel Bat Algorithm to solve numerical optimization problems. Firstly, the population of bats is divided into several independent groups, and they are independent. With every fixed number of iterations, different groups will exchange information and update. We use benchmark functions to test accuracy convergence behavior. From the analysis and summary of the experimental results, we get the following conclusions. The communication strategy improves the accuracy of BA in finding the best solution. The algorithm has improved significantly.
Due to the relatively fixed route and obvious difference between different routes, how to reduce the energy consumption level of pure electric buses is a research hotspot at home and abroad. Based on the actual operation of pure electric buses in a city as the research object and through the analysis of its starting data, the K-means clustering method is used to study the influencing factors and differences of energy consumption under different starting modes of electric buses. Then, the evaluation system of drivers’ starting behavior is built. The results show that the energy consumption of pure electric buses varies greatly under different starting modes. The energy consumption of radical starting buses is much higher than that of safe starting buses. The evaluation system can objectively and effectively evaluate drivers’ starting behaviors, provide a sufficient basis for the supervision of operating enterprises, and have certain reference value.

This system has found a feasible solution to further isolate people from garbage and prevent people from infecting bacteria.
In actual decision-making, recognizing, analyzing, and reasoning is vital to solving problems in which information plays an important part. The evidential reasoning (ER) approach provides a great way to address multi-attribute decision-making (MADM) problems, including qualitative and quantitative attributes, based on a distributed assessment framework. However, in the ER context, choosing the optimal schemes is based primarily on the aggregation of attributes’ distributed assessments. The consistency of assessments for each attribute is ignored, all that will affect the evaluation's reliability. This study puts forward a new model based on the ER to handle MADM problems, considering the consistency of attributes assessment. A reliable measure for assessments, calculated with the entropy, is figured out to represent the discrete degree of evaluating so that effectiveness and reliability and are both considered. A numerical example illustrates the decision-making process, and the properties of the new model are investigated. It is shown that the new approach is more reasonable and effective.

The difference between the subjective emotional preference and the objective cognitive formation of product attributes is an important factor affecting the online reputation of goods, but there is little research on it. This paper introduces vertical product attributes (with a unified preference standard) and horizontal attribute segmentation from the perspective of consumer cognition and emotion. It discusses the internal impact mechanism of online reputation judgment based on the Elaboration Likelihood Model. By capturing the relevant data of online reviews and product popularity on the website of JD.COM, we constructed a sentiment analysis model and conducted an empirical study on it. The results show that consumers generally pay more attention to mobile phones' vertical attributes, such as batteries and cameras. The change in reputation attitude caused by this part of attribute evaluation is more stable. Horizontal attributes such as feel and color focus are ranked lower, and even inconsistent sentiment orientation generally does not hurt reputation. But price ranks high as a horizontal attribute due to consumer preference concern. This paper puts forward specific suggestions for enterprises to improve product attributes, carry out product research and development, implement differentiated marketing, and promote brand image communication.
At present, cloud data centers' high energy consumption is an urgent problem in the development of cloud computing. One reason for the high energy consumption of cloud data centers is the mismatching scheduling between tasks and resources. The existing cloud computing task scheduling algorithms assigned tasks to resource nodes by certain rules according to the task information, and they ignored that the resource nodes are also the main body of the task scheduling algorithms. This paper proposes a new task scheduling algorithm based on bilateral selection. It fully considers the task and the resource and combines the Dynamic Voltage/Frequency Scheduling (DVFS) technology to help tasks and resources to match more appropriately. It can assign tasks to resources with higher credibility. The experimental results show that the cloud computing task scheduling algorithm based on the bilateral selection can obtain better execution performance and lower execution energy consumption and solve the high energy consumption problem caused by the mismatch between tasks and resources.
The ontology matching technique aims at establishing the correspondence between two ontologies’ entities to solve their heterogeneity problem. In the matching process, the quality of the single matcher’s alignment can not be ensured. Usually, multiple matches are required to work together to increase the evidence of potential matches or mismatches. Selecting, combining, and adjusting these ontology matches to obtain high-quality ontology comparisons is one of the main challenges in ontology matching. This paper proposes an Argumentation Framework (A.F.) based on the ontology extracting technique to address this challenge. First, the proposed approach obtains the alignments obtained by different ontology matches. It extracts the final alignment by debating the disputed entity correspondences with A.F. The experiment is conducted on the Bibliographic track provided by Ontology Alignment Evaluation Initiative (OAEI), and the statistical comparison with the state-of-the-art ontology matching techniques shows the effectiveness of the proposed approach.
