All rubrics
Release: 2014-2 (5)
Keywords: fast transformation, DCT, FFT, Wavelet, Walsh-Hadamard, NMC, NMC3, NeuroMatrix, NM6406, MB7707
Annotation: The author discusses the performance evaluation of vector computing on NeuroMatrix pro-cessors . The examples of discrete Fourier, cosine, Walsh-Hadamard and wavelet transformations are analysed. The principle of optimal algorithms design is dwelled on. The effectiveness of vector calculations on NeuroMatrix processors is demonstrated
Parameter identification problems in Mathematical modelling of processes
Release: 2014-1 (4)
Keywords: parameter identification, model structure, experimental design, local and global identifiability, parameter space
Annotation: The main stages of constructing mathematical models based on experimental data are consi-dered. At each stage the main problems of parametric identification leading to inadequate models are indicated. Special attention is paid to the property of model structure identifiability. Unidentified model structure contains a set of parameters that cannot be uniquely determined from experimental data, even for the ideal experiment. In this case the results of modeling become questionable. Illustrative examples of non-identifiable model structure are given, as well as recommendations for solving this problem.
Methodology of graphics information analysis in decision support systems
Release: 2014-2 (5)
Keywords: image analysis, bioinspired algorithms, images verbalization, description logics, linguistic variables, fuzzy attributed relational graph, pattern recognition
Annotation: This paper describes the results of the study to improve the automation degree of universality and effectiveness of the two-dimensional image processing and three-dimensional objects on the basis of famous and hypothetical models of mechanisms of biological systems.
Nanomaterials ontology model
Release: 2014-1 (4)
Keywords: mathematical modeling; ontology model; development of knowledge-based systems
Annotation: Using intelligent modeling systems for explaining the results of calculations in terms of a par-ticular domain provides more options by contrast with program systems of other classes. A formally described domain ontology that defines the unambiguous interpretation of the terms makes it possible to develop intelligent modeling systems combining knowledge and data of different sections of this domain and program systems for solving application issues. Nanos-cience is of a cross-disciplinary nature which implies the necessity to use knowledge of various disciplines, i.e. there are ontologies of other domains in this ontology. The paper proposes a mathematical ontology model of the nanomaterials domain with complicated structures and terms from ontologies of organic chemistry and physical chemistry.
