This work aims to evaluate the storing and retrieving data response time using an Ethereum Smart Contract application to verify the feasibility of its utilization instead of using relational databases in web application development. To achieve the objectives of this work. There was a comparison between the Ethereum Smart Contract and the SQLite, considering response time as the user experience for database choice decisions in future application development. This study consisted of the development of two similar applications. The first one was the Ethereum Smart Contract Application, and the other was the SQLite Application. Using these applications to build graphs of response time behavior as the number of records processed grows. For storing data Blockchain application was much faster than the SQLite application. When retrieving data, the Blockchain application usually starts slower but finishes faster than the SQLite application. Blockchain is a recent technology for secure data storage in a distributed architecture. The hypothesis to be checked was if it also has a good response time compared with other databases. The contribution of this work is to provide information about the efficiency and possible user satisfaction of Blockchain applications.

To realize the digitalization and visualization of road achives,this paper presents the MVCPF plug-in framework which is based on MVC Design Pattern and modularization programming method.According to the single responsibility principle,application is divided into some plug-in modules which follow MVC mode.Modules that stand apart from each other can be integrated as a whole by using message response and data share of MVC.Based of that,R-Trees is used to create a spatial index for the data,and achieve an efficient management of huge amounts of data,achieve in quick query of information in 3Dscene;road web3 Darchives MIS is designed out which has the characteristics of a clear structure,small size,scalability,etc.It is easy to be published,updated and expanded.The huge road 3Dscene,which contains terrain,road and attached facility models,can be transported and rendered as fast as possible.In addition,the achive information can be obtained realtimely in the web3 Dscene.

used of RSA arithmetic and Feige-Fiat-Shami digital agreement to proposal an double-direction mutual user attestation method, improved on Diffie-Hellman arithmetic, user cryptical communications project is constructed. The idea of zero-knowledge proof is used in this project to guarantee key security,and user’s communications content is hide higher.

Based on intelligent autonomous decentralized systems(IADS) and SoftMan,an organization structural model of softMan community is designed.SM.man management function,management and control strategy and coordination running mechanism are expounded.Characteristics of coordination control and forms of SoftMan Crowd are analyzed and partial-global planning(PGP) coordination control strategy is put forward.PGP may avoid task redundancy between nodes through intercommunion.Each node maintains its PGP and coordinates their behavior by PGP independently and asynchronously so as to accomplish the global task.
In this paper, a model of the automatic control of trains was researched. To research the problem, fuzzy control, predictive control and computer simulation technology were applied. The speed of the train and the comfort level were defined as evaluation functions, and the tactic used was rolling optimization.
