Modern processes in the world economy directly affect the development and changes in sea passenger ports and their infrastructure. The principles of organization of the “city-sea passenger port” system are changing and becoming more complex. Recently there has been a significant increase in passenger traffic and cruise ship and ferry traffic in Baltic Sea. Since these objects are complex technical systems consisting of many elements, in their study it is necessary to use the system approach, to solve the problem of structure synthesis and the determination of objective functions. The objective of this publication was to study how the forecast for the development of demand for sea passenger ports (number cruise ships and passengers flow for next year) could be done by combining simulation and forecast functions. These tasks depend on the qualitative construction of specialized information simulation models. Such subsystems should be used by passenger port management for both operational everyday tasks and strategic tasks. One of the main goals of the forecast is the qualitative construction of an analytical function work of the terminal that determines the passenger flow based on real data. The article considers the solution of this problem by using the method of average growth rate and polynomial extrapolation. In the article, the characteristics and infrastructural features of the passenger ports of St. Petersburg are given, and the main directions of development based on the results of simulation are considered. The paper discusses advantages of using such forecast and their introduction in the early stages of operation of the terminal. The study represents an example of analytical information used for the forecast of the terminal load, the analysis of the workload and efficiency of the organization of the marine terminal in operational tasks using analytical function based on real data

We extend the static pattern analysis method to the temporal dimension by introducing a six-type trajectory taxonomy that classifies objects according to the frequency and structure of pattern switches over an observation window of T > 8 periods. For each object, a reference pattern is designated as the most frequently occupied group over the observation ...

Toric topology assigns to each simple convex n-polytope P with m facets an n-dimensional real moment-angle manifold RZP with a canonical action of Zm2=(Z/2Z)m. We consider (not necessarily free) actions of subgroups H⊂Zm2 on RZP. The orbit space N(P,H)=RZP/H carries an action of Zm2/H. For general n we introduce the notion of Hamiltonian C(n,k)-subcomplex in the boundary of an ...

In this paper, we determine explicit bases for Riemann–Roch spaces associated with various families of elliptic codes. We establish the feasibility and provide exact algorithms for constructing bases of Riemann–Roch spaces corresponding to arbitrary divisors on elliptic curves, including the non-effective case. These results are subsequently applied to derive bases for quasi-cyclic elliptic codes and ...

We study a family of one-dimensional maps that models the dynamics of a system of differential equations with a Lorenz attractor near a bifurcation curve where the system has a pair of homoclinic loops with zero separatrix value. Of particular interest is the region of the parameter plane where the map has a robust chaotic ...

Toroidal chaos designates a chaotic solution that is structured in the neighborhood of a torus. For being chaotic, such a torus needs to be discontinuously fractalized to present a Cantor set, ensuring the great sensitivity to initial conditions required for chaos. A fractal is related to self-similarity and a non-integer dimension. In fact, although clearly ...

Clarity of knowledge and reasoning is necessary in many cases. Yet vagueness in scientific thinking related to surprise, curiosity, "ability to engage with not-knowing" (de Freitas) and abductive reasoning is also a crucially important source of scientific creativity which supplements combinatorial logic when dealing with the already known. Starting from studies by C. S. Peirce ...

One of the effective means of protecting digital images is invisible watermarking. Different scenarios have different requirements for watermark resistance to post-processing. Robust watermarking schemes are resistant to a wide range of modifications. Fragile watermarking schemes are designed for integrity control and are destroyed by even minor modifications of images. Semi-fragile watermarking schemes combine features ...
