There have been many research methods on Web service composition, and state machine is one of them. The service composition based on the state machine is easier to understand, more intuitive and clearer than other methods. However, as the number of states increases, the jump between states will also become complicated. In this regard, a solution to the service composition based on a hierarchical state machine is proposed, which uses the service state machine to transform into a service rule library, and finally obtains the hierarchical state machine by adding default states and hierarchical generation algorithms. The reachability and equivalence verification proves that the method is feasible. Secondly, in the process of Web service composition, there are situations where multiple sub-services meet the user's functional requirements. In this case, in order to meet other non-functional requirements of users, it is necessary to filter the sub-services in the set of candidate subservices. In this regard, an improved firework particle swarm algorithm is proposed. The good point set method is introduced to initialize the particle population, which improves the diversity of the particle population at the beginning of the algorithm, and uses the particle position instead of the fitness value to improve the explosion radius formula and expand the search range of the algorithm. Improve convergence speed. In order to verify the effectiveness of the proposed algorithm, the experimental data adopts the QWS data set, and compares the improved firework particle swarm algorithm with IDPSO and FWPSO algorithms. The experimental results show that the proposed improved firework particle swarm algorithm can solve Web service composition more effectively Optimization.

The Glide Path(GP) is an important navigation device that guides the landing of the aircraft. Due to the working principle and of the Glide Path antenna itself, the protection of the Glide Path protection area is very important. In this paper, we study the effect of the presence of a small group of buildings in the protection area of the Glide Path antenna on the ILS signal, and analyze the changes in the path structure of the Glide Path through 3D modeling simulation, the simulation results are in high agreement with the actual flight inspection results, and the appropriate reduction of the building height will have some improvement on the path structure.

Greedy Perimeter Stateless Routing Protocol (GPSR) is a position-based Unmanned Aerial Vehicle (UAV) Ad Hoc Network routing protocol. The data forwarding process of GPSR can be divided into two modes: greedy forwarding and perimeter forwarding. When greedy forwarding fails, it will be converted to perimeter forwarding. However, the traditional way of using the right hand rule to find the next hop node in the perimeter forwarding has the phenomenon of detour, which will make the UAV network with frequently changing topology face the problem of too much overhead. Therefore, a multi-attribute bidding model based on game theory is established to select the next hop node in the perimeter forwarding stage. Considering the forwarding Angle and distance, the scoring function and revenue model of bidding nodes are designed. Finally, the best next-hop node is selected by comparing the quality attributes and bidding prices of multiple bidding nodes. Simulation results show that, compared with the traditional GPSR protocol, the optimized algorithm used in perimeter forwarding stage can reduce delivery delay and network overhead while increasing packet delivery rate, which is suitable for the UAV network with frequent topology changes.

Air defense security is an important part of our military work. In order to solve the contradiction between "data explosion" and "knowledge lack" existing in the field of military air defense, in this paper, we adopt a more scientific way to organize and manage big data, namely, constructing knowledge graph. In this paper, we construct the ontology model of knowledge graph of air defense domain at first. Secondly, we use information extraction technology to sort, extract and clean the open source data on the Internet. Then the data that meet the requirements are added to the knowledge graph. Finally, we use the Neo4j graph database to manage and store the data in the knowledge graph.

Historical and cultural blocks have both history, aesthetics, architecture and other civilized features, and are regarded as the carrier of human urban cultural heritage. Virtual reality (VR) technology has the characteristics of visualization and high immersion, and is currently an important way of digital protection of cultural heritage and tourism display.The traditional VR cultural heritage digitization system is expensive to develop, and there is an urgent need to study a reusable virtual reconstruction development system for cultural and tourism resources. Taking the historical and cultural blocks of the First Automobile Manufacturing Plant as the object, based on geography, imagery, and actual measurement data, and using the "component library + service + interface" as the reuse architecture, research on the reusable virtual tourism application reconstruction system. The key technologies for the project solution include basic data standardization, multi-source data fusion modeling, model coordinate transformation and matching, color collection and restoration. The results can be used for the development of a three-dimensional virtual platform for large-scale historical and cultural blocks.

Flipped classroom on basis of the modern information technology has been a driving force to teaching reform in universities while traditional in-class theory teaching has not been able to meet the needs of current teaching objects. The main feature of flipped classroom is to reform the traditional education model by means of information technology, and to construct the evaluation mechanism of university education with the acquisition and analysis of big data as the platform. Through the network data platform, this paper carries out the evaluation of students’ performance in the flipped theory class of universities. The relevant data of the empirical research on the final exam scores of the experimental class and the control class before and after the experiment is used by SPSS19.0 statistical software analysis, the experimental results support that the teaching mode of flipped classroom is better than traditional in-class theory teaching. And it could be an efficient way for universities to explore the teaching innovation by applying flipped classroom.

In order to make the teaching resources fair, many cities now implement the allocation mechanism. But in the process of allocation, government staff needs to manually review a lot of work, which increased a lot of pressure to the education management department and wastes a lot of manpower and resources. Moreover, because there are persons take part in the allocation management, the public doesn’t have full trust in the allocation. In order to reduce the work pressure of government departments and improve the trust, the government should use blockchain technology to realize management system. By analyzing the business process of student allocation system, the system can store key data with alliance chain technology. Alliance chain breaks through the data barrier of information system among government departments. According to the characteristics of the alliance chain, this paper gave the overall design and business process analysis of the system, and the system experiment finally verified that the blockchain technology has very important significance and feasibility in the sunshine government. The next research work will be to design the application system by using the block chain principle, instead of using the existing block framework.

Meteorological disasters are the main factors threatening the security of modern power grid, and transmission lines, as the carrier of power transmission, are more easily restricted by the complex and changeable natural environment. Therefore, a risk assessment model based on entropy weighted grey correlation analysis algorithm is proposed. Firstly, the risk of various meteorological disasters is analyzed, and the quantitative expression model of disaster factors is established; then, the correlation between disaster information and transmission line is extracted by using the improved algorithm of multiple grey correlation analysis with entropy weight. Finally, the risk assessment of line operation is realized based on the risk assessment model. The experimental results show that the application of the risk assessment model improves the power grid risk early warning ability and intelligent monitoring level.
