Big data analytics has had a significant impact on various industries as a technology that is still in its infancy. The engineering sector is no exception, and big data analytics is becoming increasingly important in improving engineering costs' accuracy ...

Population movement between regions is one of the main ways for the spread of COVID-19. The Chinese government has adopted unprecedented population movement controls to restrain the spread of COVID-19. With the development of information society, the ...

Aiming at the problem that the risk coefficient of power grid load is too high in the existing methods for power grid location, in order to improve the safety of power grid operation around the airport, a rapid location technology of power grid around ...

While they brought about significant reforms in traffic data collection, traffic planning management, and traffic flow prediction, the problem of massive data synergy has also become increasingly prominent. This paper explores the data governance and ...

Dense and complex crowds are prone to overcrowding and trampling accidents when traveling through a narrow throughway, and it is of practical interest to study the simulation of crowd evacuation under the influence of emotions in a narrow throughway. In ...

We explore the optimal decision-making of a repurchase contract coordinated supply chain under stochastic price conditions with asymmetric cost-of-sale information and risk aversion of suppliers. A new repurchase contract model is constructed on the ...

With the increasing prosperity of maritime transport, the tank cleaning process is particularly important. In order to reduce the probability of accidents caused by ship cleaning and improve the safety, this paper applies the analytic Hierarchy process (...

In the context of frequent social emergencies, more and more enterprises are actively exploring the innovation path and resilience management of supply chain driven by strong realistic needs, but there is no consistent conclusion on the relationship ...

In order to further improve the effect of electricity fee recovery risk early warning, this study designed a new electricity fee recovery risk early warning model based on clustering data cleaning. Based on the clustering data cleaning algorithm, ...

Based on the exogenous shock event of the establishment of the Pilot Free Trade Zone (FTZ), this paper takes the data of China's A-share listed companies from 2012 to 2022 as a sample, and further empirically tests whether the FTZ policy can inhibit the ...

In view of the possible typhoon, fire and earthquake in Hainan, this paper focuses on the research of VR power training project based on extreme weather. First, the potential impact of extreme weather on the power system in Hainan is described, and a ...

In order to improve the efficiency of older users' use of information systems and to motivate them to learn and explore the different functions of information systems, research on the adaptive information behaviors of older users is needed. This paper ...

In the cooperation of agricultural supply chain, due to the asymmetric information of production and marketing, the profit distribution among supply chain subjects often appears "high in the middle and low at both ends". With the development of the new ...

In an effort to better estimate the cargo throughput of Xiamen Port, a grey Markov prediction model was created. Relevant data of Xiamen Port from 2006 to 2022 were selected for prediction, and the predicted values were firstly derived using the DGM (2, ...

The Space-ground integrated network consists of deep space network, space network and ground network. The ground network is vulnerable to network attacks due to its complex networking structure, high randomness of device access, limited node processing ...

This paper presents a novel approach to predict fuel flow during the climb phase in aviation, a critical stage where fuel consumption is significantly high. Utilizing advanced machine learning algorithms, notably the XGBoost regression model, we ...

In this paper, a secure hash function (PS-SHF) based on the parallel structure is proposed. By designing the initialization of the link variables of the hash function, introducing logistic chaos mapping, and the design of the parallel structure, a more ...

Elevator-related accidents, though infrequent, can have severe consequences. To comprehend and mitigate the underlying causes, this research delves deep into the realm of the Trajectory Intersection Theory. By systematically analyzing national safety ...

The number of autos in China has surpassed 312 million, and automotive insurance is the most important part of property insurance. A win-win scenario for policyholders and property insurance firms may be achieved by precisely predicting the amount of ...
