We consider systems of companies which have financial interests in each other and develop principles by which the real interest of one company in another can be determined. The paper develops an algorithm to calculate true interests from a weighted digraph that encodes the direct and indirect...

The author proposes the semi-classical expansion of the distribution function using modified Hermite polynomials to calculate moment equations for quantum gas. The completeness of the semi-classical expansion of the distribution function is not satisfied, whereas we can conjecture that moment...

We apply a previously derived and utilized a modified Navier–Stokes equation to the Taylor–Couette flow, that is fluid flow enclosed between two concentric cylinders where the inner cylinder is rotating with some constant speed and the outer cylinder is stationary or vice versa. We report...

The dynamical origin of opinion polarization in the real world is an interesting topic that physical scientists may help to understand. To properly model the dynamics, the theory must be fully compatible with findings by social psychologists on microscopic opinion change. Here we introduce a...

In this paper we consider an information theoretic approach for the accounting classification process. We propose a matrix formalism and an algorithm for calculations of information theoretic measures associated to accounting classification. The formalism may be useful for further...

This paper presents a study of variations of fuel consumption and emissions of vehicles due to random street crossings of pedestrians. The pedestrian and vehicle movement models as well as the interaction model between the two entities are presented. Extensive numerical simulations of single and...

Social factors, such as public opinion, values, ethics, moral standards, could guide people’s behavior to some degree. In this paper, we introduce social orientation as a motivator factor into the Nowak model, and discuss the variation of cooperation proportion under the function of motivator...

Power system and its communication system, which can be called a cyber-physical system, are interconnected and interdependent on each other. This paper considers the interaction problem between power system and its communication module from the perspective of the topological structure. Firstly,...

Thermal energy applied to particles in conservative vector fields results in an increase in the potential and kinetic energy causing an increase in entropy. However, conservative fields associated with potential energy gradients of the system act in opposition to the kinetic energy gradients...

Influence maximization problem is about finding a small set of nodes from the social network as seed set so as to maximize the range of information diffusion. In this paper, the theory of coritivity and method of finding core nodes in networks are introduced to deal with this problem. From the...
