An identity-based distributed key management scheme for airborne ad hoc networks is analyzed. It is demonstrated that in the generation phase of user private key, the user identity certificate is transmitted in the public channel, so that the attacker can use the intercepted identity certificate to fake the legitimate node and cheat the distributed key generation center to generate private key for it. Then, an improved authentication scheme is proposed. It constructs the signature of timestamp using the private key of the user node as authentication proof, so that the attacker can't forge the authentication information. It is showed that the improved scheme can effectively resist the forgery attack, and further reduce the computing cost of user nodes while realizing all the functions of the original scheme.

Nitrogen oxide (NOx) emissions play an important role in the study of diesel engine pollutant emissions. This study introduces the long short-term memory (LSTM) neural network to estimate the transient NOx emissions of diesel vehicles. The LSTM deep neural network is used to build the prediction model to ensure the stability as well as the accuracy of the model. The results show that the model has better predictive performance and stability than the two commonly used benchmark models, and the following conclusions are drawn: (1) LSTM has better learning and prediction ability for transient changes in NOx emissions. Compared to prediction with random forest (RF) and support vector regression (SVR), the mean absolute deviation and root mean square error of LSTM are reduced by about 23.6% and 8.3% at least, which also indicated that the input parameters selection method was effective. (2) LSTM is a general estimation approach for time series data, which can reduce the suppression effect of transient data changes on model prediction, and has high prediction accuracy, and can be employed for real road NOx emission analysis.

The thesis takes the station parameters in the three systems of utilization, simultaneous line loss, and theoretical line loss as the analysis object and develops an auxiliary analysis and management system for abnormal line loss in the station area. The system starts to treat the line loss problem in the station area. Use data clustering to analyze the statistical line loss in the regular, economic, and high-loss intervals in the three sets of system parameters, form typical parameters as the results of big data analysis and apply them to the three systems. Data governance and line loss governance make decisions.

By analyzing the text of maker space policy, it is helpful to understand the logic of policy expression and evolution. The co-word analysis method, ROSTCM6.0 and Netdraw systems are used to compare and analyze 81 policy texts with Beijing, Hubei, Sichuan and Jilin as typical representatives. The study found that different regional policy texts have basically the same policy value orientation in terms of service awareness, platform construction, fiscal and taxation policies, etc., while the differentiation level is manifested in incorporating regional resource endowment into the expression of policy texts, thus highlighting advantages and forming social influence. The research conclusion provides empirical evidence for further improving maker space policy.

With edge devices playing an increasingly important role in our daily lives, edge computing and human-computer interaction, especially facial expression recognition, become research central issues in academia and industry. However, surprisingly, utilizing edge computing and neural networks for facial expression recognition has been neglected for many years, very few research can be found. To be focusing on such topics. In this paper, we improve Visual Geometry Group 19 with the idea of residual learning. To be specific, for each block of Visual Geometry Group 19, we add its input to its output. The result of the addition will be the input of the next block. Then, we minimize the size of our model by pruning and post-training quantization to achieve a higher efficiency and maintain the model's accuracy at the same time when deploying it on edge devices. The experiment result shows that our model has a 98.99% accuracy on the CK+ dataset. Besides, when deploying on edge devices, its inference time is less than many other popular neural networks that are designed for deploying on edge-devices.

With the rise of major video websites, the scale of video website users is expanding. Users are the core of all video websites, so it is of great significance to study video website DAU to evaluate and guide its operation. Based on the data of a video website DAU and platform layout from January 2017 to December 2018, this article analyzes the influencing factors of the video website DAU, selects 10 influencing factors from broadcasting arrangement, content level, content mode, and winter and summer vacations, constructs a Random Forest model, makes regression prediction on the daily average DAU of the video website and calculates the importance of 10 variables.

Handover authentication scheme for mobile network enables mobile nodes to roam safely on different access points. Recently, a handover authentication protocol called pairhand and its improved scheme have been proposed, which are superior to all other schemes in security and efficiency. However, both schemes are based on bilinear pairings, which is a complex operation. In this paper, a novel pair-less handover authentication protocol is proposed. It eliminates the pairing operations, and further reduces the computation cost on mobile user without losing any security features.
