This paper presents a method for optimal point-to-point control of linear discrete-time systems with time-varying non-convex state constraints, as arising for problems of avoiding moving obstacles. While common approa...

In neutral point indirectly grounded systems, phase-to-ground fault is putting new demands on fault diagnosis technology. Information fusion is applied to detect the phase-to-ground fault, which integrates several sources of information, including line current, line voltage, zero sequence current and voltage, and quintic harmonic wave component. This method is testified through the simulation of Matlab. Simulation results show that the precision and reliability of the detection has been greatly increased.
This paper deals with the problem of controlling linear complex networks in an efficient way, i.e., with limited control energy. A general principle is provided, based on the eigenvalues of the network. It is shown nu...

In this paper, we study the problem of controlling complex networks with unilateral controls, i.e., controls which can assume only positive or negative values, not both. Given a network with linear dynamics represente...

This paper presents measures for ensuring high level information security for enterprise systems. These mechanisms are based on the correlation of the events with risk factor, collected from the security systems deployed in the company's infrastructure. The role of event correlation systems is to detect real time security threats and to notify security personnel about those breaches, in order to take measures to reduce the impact of the threat. Our personal contributions in this field consist in creating correlation rules meant to ensure enterprise sensitive data confidentiality inside the company, mostly compromised by employees, and to secure industrial processes targeted by worms. We are also extending the functionality of the event correlation systems from alerting capabilities to real time response capabilities. Also, we conceived additional measures to secure the correlator, which involve approval workflows and encryption techniques.
