In this paper the problem of the HIV/AIDS spread reduction is addressed in the framework of optimal control theory. A model recently proposed has been adopted;it considers two classes of susceptible subjects, the wise people and the people with incautious behaviors, and three classes of infected, the ones still not aware of their status, the pre-AIDS patients and the AIDS ones. The control actions involve prevention by information campaign, to reduce the category of subjects with unwise behavior, by test campaign, to reduce the number of subjects not aware of having the virus, and medication on patients with a positive diagnosis. A cost index aiming at the reduction of patients with positive diagnosis is introduced with the conflicting requirements of using as less resources as possible. © 2018 IEEE.

Smart meters enable improvements in electricity distribution system efficiency at some cost in customer privacy. Users with home batteries can mitigate this privacy loss by applying charging policies that mask their underlying energy use. A battery charging policy is proposed and shown to provide universal privacy guarantees subject to a constraint on energy cost. The guarantee bounds our strategy's maximal information leakage from the user to the utility provider under general stochastic models of user energy consumption. The policy construction adapts coding strategies for non-probabilistic permuting channels to this privacy problem. Copyright © 2019, The Authors. All rights reserved.

arXiv 2020年

Quantum communication complexity studies the efficiency of information communication (that is, the minimum amount of communication required to achieve a certain task) using quantum states. One representative example is quantum fingerprinting, in which the simultaneous message passing model is considered and the minimum amount of communication could be exponentially smaller than the classical fingerprinting protocol. Experimental demonstrations based on a practical quantum fingerprinting protocol where coherent states are used to construct the fingerprints, have successfully shown the superiority of quantum fingerprinting. However, as a consequence of using coherent states, the communication time in this coherent quantum fingerprinting (CQF) protocol is increased. Moreover, the minimum amount of information communicated in these experimental demonstrations is largely limited by the dark counts of the single photon detectors. Here, we propose to enhance the performance of the existing CQF protocol through applying wavelength division multiplexing (WDM) and simultaneous detection of multiple wavelength channels. We show that the new WDM-CQF protocol can potentially reduce the communication time significantly. More importantly, with the same experimental parameters, the amount of communication is much reduced in the new scheme compared with the original CQF protocol. The more wavelength channels are used, the less communication is required by WDM-CQF protocol. We also perform a proof-of-concept experimental demonstration of the new WDM-CQF protocol with 6 wavelength channels. The experimental results further validate that the new scheme with WDM not only beats the classical protocol, but also reduces the amount of communication required by the original CQF protocol by more than half.

This paper proposes a system, by which humanoid robots could imitate human movements to learn human behaviors. Considering the security problem during humanoid robot imitation process, a method of stability identification based on improved Multi-Layer Perception (MLP) is proposed. Firstly, the positions of the human joints are collected by a Kinect. Secondly, the human joints information is transformed into robot angles information by the inverse kinematics equation. Finally, the stability of the robot is identified by the deep neural network, which has the robot angles as its input. Simulations and experimental results demonstrate that compared with the Back Propagation neural network (BPnn), RBF neural network (RBFnn), Support Vector Machine (SVM) and Extreme Learning Machine (ELM), MLP neural network has the best identification accuracy. And the filters we used can overcome the problem of speed pulse, to some extent, and achieved an ideal imitation result.

In this paper, we studied the influence of the presence of a wide river on electromagnetic fields generated by lightning strikes to a tall tower located on a high mountain, using the three-dimensional finite-difference time-domain method. In the computations, the lightning channel and the tower are represented by the transmission line model extended to include a tall strike object. Electromagnetic fields are computed at different points located in the river and above the ground. It is shown that the peak value and the electromagnetic field waveforms, computed at the considered observation points, are significantly affected by the presence of the river.

Electrocardiograms are generated by electrical signals, and therefore individual electrocardiogram signals can vary according to the measurement environment that is created by the subjects' behavioral characteristics. Generally, post-exercise electrocardiograms that are used as biometric identification data do not match pre-exercise electrocardiograms owing to temporarily occurring tachycardia, and this reduces user identification performance. Research is being conducted on normalization techniques that make the post-exercise electrocardiograms match the pre-exercise electrocardiograms, but there have been problems caused by the distortion of morphological features such as P waves, QRS complexes, and T waves. To address problem, this study looked at the measurements of electrocardiograms before and after exercise and performed linear interpolation normalization on the P and T waves of a post-exercise tachycardia electrocardiogram cycle to make it match the pre-exercise electrocardiogram cycle. This study also proposes a user recognition system based on this technique. To analyze the proposed system's performance, the lead-I electrocardiogram signals of 20 subjects were measured three times at 2- to 3-day intervals before and after exercise, and a database was constructed. The experiment results showed that the conventional algorithm's maximum recognition performance was 88.33%, and the proposed normalization method's performance was 91.67%. A combined method was found to be both excellent and similar to the proposed method, with a performance of 92.5%.

This paper presents the architecture and control of a LLC bidirectional isolated DC-DC converter with unity gain for low power application. The converter features zero voltage switching (ZVS) at light loads, which results in reduced switching loss and thus improves the efficiency. Further improvement of the efficiency has been achieved by operating the converter in burst mode with a constant switching frequency. A control scheme that allows bidirectional power flow is proposed. High frequency ferrite core transformer provides the galvanic isolation between primary and secondary. In addition, resonant inductors have been integrated in the transformer, which reduces the size and cost of the converter. Experimental results show power transfer efficiencies more than 90 % for loads between 1 W to 8 W. © 2018 IEEE.

This paper presents a control strategy for Cyber-Physical System defense developed in the framework of the European Project ATENA, that concerns Critical Infrastructure (CI) protection. The aim of the controller is to find the optimal security configuration, in terms of countermeasures to implement, in order to address the system vulnerabilities. The attack/defense problem is modeled as a multi-agent general sum game, where the aim of the defender is to prevent the most damage possible by finding an optimal trade-off between prevention actions and their costs. The problem is solved utilizing Reinforcement Learning and simulation results provide a proof of the proposed concept, showing how the defender of the protected CI is able to minimize the damage caused by his her opponents by finding the Nash equilibrium of the game in the zero-sum variant, and, in a more general scenario, by driving the attacker in the position where the damage she/he can cause to the infrastructure is lower than the cost it has to sustain to enforce her/his attack strategy. © 2018 IEEE.

Microgrid control becomes more and more developed with the application of this concept on a larger scale. This paper defines the modern microgrid concept and evaluates the possible architectures and control hierarchy. A small scale microgrid architecture is proposed. The components of the system are a wind turbine, a photovoltaic panel and a household. The model was implemented in Matlab/Simulink and a decision table control was proposed. The proposed decisions and actions are defined for both on and off grid operation, in order to benefit most of the local resources. The results of this study are promising in terms of microgrid off grid operation for single dwellings, considering that the house is grid supplied for a period of only 4 hours of the day. © 2018 Politechnica University of Bucharest.
