Network traffic anomaly detection has become a popular research tendency, as it can detect new type attacks in real time. However, the network traffic appears as a complex dynamic system, causing by the collaboration of many network factors. Although various methods have been proposed to detect anomalies, they are mostly based on the traditional statistical physics. In these methods, all factor...

Only recently a new stylised fact of economic growth has been introduced, the bimodal shape of the distribution of per capita income or the twin-peaked nature of that distribution. Drawing on the Summers/Hestons Penn World Table 5.6 (1991) we determine kernel density distributions which are able to detect the aforementioned twin peaked structure and show that the world income distribution start...

Discrete-time synergetic optimal control strategies are proposed for a class of nonlinear discrete-time dynamic systems, in which a special performance index is used that results in closed-form solutions of the optimal problems. Reduced-dimension aggregated variables representing a combination of the actual controlled plant variables are used to define the performance index. The control law opt...

We introduce the Synergetic approach, which brings great improvements in computer modeling and simulation of power electronic systems. Essentially, the process involves synthesis of control laws that result in collapse of (at least two) initially high-dimension models into a single model of lower-dimension. The technique requires creation of state space attractors, artificial manifolds, that re...

Project portfolio configuration (PPC) is an important approach to maintain the sustainable 12 development of enterprises and achieve organizations’ strategy. However, the synergetic efficacy 13 of PPC which determines the degree of the project's strategic objectives achieved is a fuzzy problem 14 and hard to be measured. To solve this problem, this paper takes the data envelopment analysis 15 (...
