Current large-scale applications, such as trading systems, blockchain, social software, etc, are increasingly adopting microservice architecture, which bring challenges to manual operation and maintenance, intrusion detection. In both operations and intrusion detection, there are a common characteristic that service metrics and network traffic are normal for most of the time, but anomaly data is more important. In this paper, we propose an unsupervised anomaly detection algorithm based on convolutional neural network with Spectral Residual, which is verified experimentally and has potential application capability with 19.2% f1-score improvement compared to the Variational AutoEncoder. © 2022 IEEE.

Numerical simulation is the default method for the study of shock wave evolution process, but it requires thousands of CPU cores and takes a long time for computation. Moreover, when the initial and boundary conditions change, the simulation needs to be recalculated. Therefore, numerical simulation cannot meet the needs of rapid evaluation and real-time display. In this paper, an encoder-decoder network structure based on ConvGRU-ODE is proposed to accelerate the simulation of shock wave evolution process, Given the experiment parameters, the proposed method can calculate the pressure effect field at each time by only using the calculation parameters. The algorithm only takes 120 seconds to calculate the shock wave evolution process of a single scene, which is significantly faster than the numerical simulation. The average relative error of pressure effect field in important areas is less than 10%, which is acceptable in engineering practice. The algorithm has good adaptability and can be applied to different scenes. © 2023 SPIE.

The designing of network performances indexes are critical to respond to the factors that assess network performances. In this study, a novel assessment method for designing network performance indexes based on combined trapezoidal and intuitionistic fuzzy information axiom. First, the network performances indexes are designed with the customer-expected functional requirement (FR) and the existing FR as the design range and the system range respectively. Then the information content of qualitative and quantitative indexes, which facilitates the selection of the best alternative with minimum information content, are calculated separately and standardized. To solve this issue of the integral characterised by fuzzy bounds, this study proposes a defuzzification method to convert fuzzy bounds into crisp numbers. Finally, the assessment is performed to demonstrate the effectiveness of the developed approach. © 2023 SPIE.

Reducing training costs, shortening training time, and improving training quality are important issues faced by equipment training. Electronic training will become the main way of modernizing weapons and equipment training. The S6000T standard is a set of equipment training standards jointly developed by Europe and the United States, which has become a common military civilian standard to support the formation of efficient training capabilities, but no software products on the market support. Therefore, on the basis of analyzing the requirements for electronic training, this article firstly proposes a workable equipment electronic training scheme based on S6000T. The article provides the framework and software implementation technology architecture of the equipment electronic training platform. Design software functions based on equipment training requirements. Implement an equipment electronic training system using platform independent J2EE and Ajax technologies. The system has been used in the training of multiple sets of equipment, and its safety, user-friendly interface, interactive graphics and text, and universality have been verified. © 2024 IEEE.

Time-resolved K-shell x-ray spectra of nanosecond laser-produced titanium tracer in gold plasmas

A study of a nanosecond laser irradiation on the titanium-layer-buried gold planar target is presented. The timeresolved x-ray emission spectra of titanium tracer are measured by a streaked crystal spectrometer. By comparing the simulated spectra obtained by using the FLYCHK code with the measured titanium spectra, the temporal plasma states, i.e.,the electron temperatures and densities, are deduced. To evaluate the feasibility of using the method for the characterization of Au plasma states, the deduced plasma states from the measured titanium spectra are compared with the Multi-1D hydrodynamic simulations of laser-produced Au plasmas. By comparing the measured and simulated results, an overall agreement for the electron temperatures is found, whereas there are deviations in the electron densities. The experiment–theory discrepancy may suggest that the plasma state could not be well reproduced by the Multi-1D hydrodynamic simulation, in which the radial gradient is not taken into account. Further investigations on the spectral characterization and hydrodynamic simulations of the plasma states are needed. All the measured and FLYCHK simulated spectra are given in this paper as datasets. The datasets are openly available at http://***/10.57760/sciencedb.j00113.00032.
