Coal washing and sorting plays a vital role for coal production. Reasonable scheduling of washing and sorting equipment, crushers and various coal silos in the coal washing and sorting process can effectively increase the total value of product coal and reduce the total energy consumption of equipment. In this paper, a multi-constrained nonlinear mixed integer programming model considering the start and stop of each equipment in the washing process is established to realize the specific regulation of the washing process. In order to overcome the problem such as local convergence when solving high-dimensional space problems, a two-stage fuzzy heuristic algorithm is proposed in this paper. In the first stage, a variety of population genetic algorithms based on fuzzy adaptive strategy control are designed for global search to establish an elite population bank to preserve high-quality individuals produced by various groups. In the second stage, an improved simulated annealing algorithm is used to perform a local search with a backtracking process on specific neighbors of individuals in the elite population bank, which can improve the stability of the algorithm and reduce the situation of falling into local convergence. Then the real data of a Chinese coal mining company was used for experiments, where the proposed algorithm is compared with other commonly used methods. The experimental results demonstrate that the proposed algorithm can increase the total coal value of the washed product by at least 1.7% compared to other algorithms, and the average total number of starts and stops of the equipment is reduced by about 7.3%, which are effectively beneficial for the related enterprise. © 2024 IEEE.

Nowadays, machine learning is widely used in malware detection system as a core component. The machine learning algorithm is designed under the assumption that all datasets follow the same underlying data distribution. But the real-world malware data distribution is not stable and changes with time. By exploiting the knowledge of the machine learning algorithm and malware data concept drift problem, we show a novel learning evasive botnet architecture and a stealthy and secure C&C mechanism. Based on the email communication channel, we construct a stealthy email-based P2 P-like botnet that exploit the excellent reputation of email servers and a huge amount of benign email communication in the same channel. The experiment results show horizontal correlation learning algorithm is difficult to separate malicious email traffic from normal email traffic based on the volume features and time-related features with enough confidence. We discuss the malware data concept drift and possible defense strategies.

Deploying reconfigurable intelligent surfaces (RIS) in vehicular networks can effectively improve the quality of wireless channel and increase network throughout, which is realized by optimizing the phase shifters. However, the dynamic network environment and complex multi-user interference seriously affect network reliability. Enhancing transmission powers blindly cannot solve the interference problem but also reduces the transmission efficiency of the RIS-based vehicular networks. To address the above challenges, this paper proposed a joint optimization scheme of transmission beamforming and phase shift. Based on the block coordinate descent (BCD) theory, this paper decomposed the scheme into two sub-problems: transmission beamforming optimization and RIS phase shift optimization, and the joint optimization algorithm was developted. Simulation results have demonstrated that the transmission rate has been improved with the assistance of RIS, with the multi-user interference effect being well-depressed. © 2024 Technical Committee on control Theory, Chinese Association of Automation.

This paper mainly focuses on a disturbance rejection control methodology for a series of mismatched and matched disturbed complex systems. Firstly, a novel finite-time arbitrary-order extended state observer (A-ESO) is proposed to accurately estimate the system states, disturbances, and their corresponding order derivatives. And then, a novel concise nonrecursive control ideology utilizing all the estimations of A-ESO is proposed to strictly guarantee finite-time stability and convergence of the whole closed-loop system. Significantly, compared with the existing nonrecursive control methods, the essential characteristic is that all the estimation information is utilized to construct the composite controller. This will be tremendously conducive to cost-saving and promoting practical implementations. © 2023 Technical Committee on control Theory, Chinese Association of Automation.

A new variable tap-length LMS algorithm is proposed in this paper. This algorithm can effectively obtain both fast convergence rate and small steady state error by non-linear weighting L errors of the current moment and past moments. The algorithm analysis is also given which the ideal tap-length is obtained by increasing the error information and eliminating the effect of correlated noise sequences. Then the new algorithm is applied to the fixed satellite communications system in which the channel is affected by weather conditions attenuation and multipath effect. Simulation results are presented to support the analysis. The new algorithm converges faster than usual algorithms under same steady state performance. The signal BER performance is greatly improved with the new adaptive filter algorithm equalizer when the signal passes simulation model of fixed satellite communications system. © 2010 IEEE.

To enhance classification performance by making use of easily availab.e unlab.lled data to overcome the scarcity of lab.lled data, this paper proposes an Embedded Co-Adaboost algorithm that integrates multi-view learning into the Adaboost learning framework and at the same time leverages the advantages of Co-training algorithm for performance enhancement. Experimental results demonstrate the effectiveness of the proposed algorithm in terms of the convergence rate, the accuracy, and the steady performance as compared to the original AdaBoost algorithm, without relying on redundant and sufficient feature sets. As a algorithm application in software engineering, the Embedded Co-AdaBoost has been applied to the classification of software document relations to improve the quality of the architecture design documents and the reusability of design knowledge. © 2012 IEEE.

It has been proved that Asymmetric cryptography can be used in Wireless Sensor Networks (WSNs). In this paper, we propose a secure Identity-based routing protocol, which can ensure that the nodes in routing discovery process are trusted nodes. Digital signatures based on ECC is used in our protocol, therefore, our protocol has many virtues, such as less energy cost, more rapid calculation, shorter storage keys, etc. In the routing discovery process our protocol can also resist multiple attacks. Simultaneously, the protocol sets an energy threshold for the nodes in the network. The nodes whose energy remained less than the threshold do not participate in the selection of the routing nodes. This can avoid the energy exhaustion in the process of data transmission so as to influent the operation of the network. © 2011 IEEE.

In order to solve the problem of system performance degradation caused by the difficulty of communication between heterogeneous devices and the large scale of devices under the traditional industrial Internet, this paper proposes a cloud control platform architecture based on the industrial Internet combined with cloud control technology, and uses this architecture to build a cloud control platform. The data engine technology is used to parse different protocols, thus solving the problems of mutual communication and data synchronization between heterogeneous devices. In addition, the cloud control technology is used to dynamically adjust the computing power of the platform to avoid the degradation of platform performance due to the increase in the number of devices. Finally, based on the platform design and construction of an unmanned factory for intelligent manufacturing, the experiments show that the cloud control system architecture proposed in this paper is scientific and effective. © 2022 IEEE.
