## Modeling an artificial biological cell in a fine-grain structure

Two models of an artificial biological cell, built in a fine-grain structure, are presented. They can be elements of computing structures that mimic the properties of living organisms - growth, self-reproduction, self-healing. The models are built on the basis of the Parallel Substitution Algorithm, which is a spatial system for...

## A CA-model of population dynamics of organisms living in Baikal. Verification and investigation of pollution influence

The CA-model was modified in order to take into account the birthrates seasonal dependency and the influence of water streams on movements of organisms. The model was verified within the production-to-biomass and the relative average quantity criteria. A difference in the verification results and the assessments of physical values is...

## Cellular automata diffusion models for multicomputer implementation

Simulating large-scale phenomena by Cellular Automata (CA) meets the problem of designing CA models that could be efficiently implemented on supercomputers with distributed memory. Since most of large-scale spatially distributed processes contain diffusion as a component which takes a significant part of computational time, the study of coarse-grain parallelization characteristics...

## A two-layer cellular automata model of carbon monoxide oxidation reaction

A two-layer cellular automata (CA) model of carbon monoxide (CO) oxidation reaction on platinum is developed and investigated. The reaction in non-equilibrium conditions can be accompanied by various spatio-temporal patterns such as surface waves, spirals and turbulences. A two-layer CA is a parallel composition of the two CA – the...

## Designing a collision matrix for a cellular automaton with rest particles for simulation of wave processes

We consider the single-particle HPPrp Lattice Gas Cellular Automata for simulation of modeling wave processes. The HPPrp Cellular Automaton is defined on a two-dimensional square lattice. Each cell of the automaton contains particles of the two types: the moving particles and the rest particles. Inserting the rest particles leads to...

## On reliability of wireless ad hoc networks with imperfect nodes

In this paper, we present a new network reliability measure that is useful to evaluate performance of ad hoc networks with imperfect nodes and perfectly reliable links. An ad hoc network is modeled as undirected probabilistic graph. A specific feature of our model is that a network contains initially excessive...

## Constructions used in associative parallel algorithms for undirected graphs. Part 2

This paper selects constructions used in a group of algorithms for undirected graphs represented as a list of edges and their weights on a model of associative (content addressable) parallel systems with vertical processing (the STAR-machine). To this end, the paper first analyzes the implementation of the Prim-Dijkstra algorithm on...

## Parallel template implementation of Particle-in-Cell method for hybrid supercomputers

Recently, hybrid (GPU-equipped) supercomputers have attained a very high performance level. The fact is, the solution of real physical problems with such supercomputers is restricted by the GPU programming complexity.

In order to simplify the development of high-performance plasma physics codes for hybrid supercomputers, a template implementation of Particle-in-Cell (PIC)...

## Defect detecting in multi-element photodetector by wavelets and neural networks

We consider the application of wavelet transform and neural networks to solving the problem of defect detection (the lack of elements and the presence of adhesions elements) in multi-element photodetectors by processing their images. It is shown that both methods can be successfully applied to the detection of defects. Found...

## An algorithm for registration of erythrocytes on low-contrast images

An algorithm for counting the erythrocytes on low-contrast images of cytological preparations is proposed. The algorithm deals with low-contrast images: brightness histogram normalization, contrast stretching, and background alignment by the “top of hat” method. Erythrocytes are detected by the similarity criterion of reference samples and an area in the picture...

## Cellular automata simulation of self-organization in the bacterial MinCDE system

The MinCDE protein complex is present in *Escherichia coli* and some
other bacteria. *In vivo*, the MinCDE prevents incorrect cell division. *In vitro*, the
MinCDE forms the protein waves and some other patterns. Recently, a hypothesis
has been proposed, which says that *self-organization in the MinCDE system arises...*
