Method of Dedetermination for Intractable Problems of Mathematical Modelling

In this paper we propose the method of dedetermination as a new method designed to solving a problem of calculation of deterministic functions with the so-called singular points where the function does not take a certain value. The aim is to develop an approach that allows for division by zero and thus exclude singular points of such functions. The proposed method is to move from problematic (from point of view of calculating) determined function to the corresponding not determined (interval) function by replacing determined function parameters by corresponding interval parameters. Due to this change the values of the function at the singular points will be well-defined interval and values. The latter allows you to solve the problem of finding the function meaning. The solution to this problem is achieved by legalization of division by zero by intervalization of calculations. It uses the principle of cutting out a neighborhood of zero in the interval being the denominator of the fraction representing studied function. For the simplified by cutting out interval function the effective formulas are derived based on the main provisions of interval mathematics and make it easy to calculate the value of this function. The proposed in the article approach to the problem of calculating functions with singular points is important for all those classes of systems in which the problem really exists. It is about the systems which functions have any number of specific points. Such systems are found mostly in telemetry, reliability theory and practice, humanitarian and many others areas. Features of these areas is that they do not always apply the classical methods of deterministic mathematics. This leads to search for new approaches to solving problems that arise here.

AL-Stable Methods in ODE Solving for Isotope Kinetics Problems
of Reactor Systems

The development of advanced reactors with the new fuel compositions, the improvement of accuracy and reliability for safety justification of facilities with the high burnout spent nuclear fuel require the accurate calculations. In engineering calculations are traditionally used ~ 200—400 elements for the solution of the isotope kinetics problems of reactor systems. The widely used ORI-GEN programs for modeling transitions in chains of transformations do not provide computation of errors for all fission products (~ 1800) of irradiated fuel. The article analyzes the possibility of applying the AL-stable implicit methods with a variable step of ODE solution, which was realized in the MZK program for the problem decision of the isotope kinetics of reactor systems.

Method of Statistical Few View Reconstruction of Geometrical Characteristics of Three-Dimensional Objects by their Discrete Projection Images

In this paper the method of statistical few view reconstruction of the geometrical characteristics of three-dimensional convex objects of irregular shape which are approximated by an ellipsoid of General form is under consideration. The statistical reconstruction is carried out with the usage of the basic features of a triad of its mutually orthogonal two-dimensional discrete projection images. The areas of two-dimensional projection images of an object and its linear sizes of one-dimensional projection images are taken as the basic characteristics. While describing an object sizes, we consider that the spatial geometrical characteristics of an object are its linear (dimensional) sizes and the average projected diameter of a three-dimensional image of an ellipsoid of General form, which approximates this object. While describing the object shape, we consider that the spatial geometrical characteristics of an object are represented by the coefficient of asphericity that is determined as the ratio of the maximum and minimum dimensions (axes) of the approximating ellipsoid.

Protection of Structural Noise Radio Channel Frequency Shift Keying

The development of robotic systems requires a stable control channels. Robotic systems control channels have to work in conditions of jamming. To control the mobile robot system justified the use of radio. However, radio is the source of interference. The most dangerous are the structural obstacles that could lead to the interception control robotic systems.
To combat Jamming use broadband systems and complex signals. But these measures are good for controlling robotic systems at small distances. At large distances FSK signals used in control channels.
The process is called staging structural interference simulation imposition. The ability to resist the imposition of imitating simulation called resistance.
When simulation imposing form interference that have a structure similar to the structure of the control signals. As a result, there is a demodulator uncertain situation to make a decision.
Fast moving robotic systems allow only non-coherent signal processing. Due to the complexity of the software synchronization signal and interference, electronic countermeasures will not always be effective. To assess the effectiveness of jamming is proposed to use a coefficient that takes into account the degree of simulation imposing. The coefficient ranges from zero to one. When the unit comes complete coincidence in time and signal interference. If the signal energy and noise energy have the same values, the demodulator decides randomly.
When imposing simulation reconnaissance signs appear in the form of parasitic amplitude modulation. This effect allows you to detect the fact of setting structural interference and take measures against suppression.
To combat simulation imposition suggest the following method. Of the affected signal interference sequentially subtract test signals, which correspond to the information symbol "zero" and the information symbol "unit". Then again, the result is subtracted from the affected structural hindrance signal. When the test signal coincides with a signal interference affected reconstructed signal obtained as a result of these operations. If the test signal does not coincide with the staggered structure signal, the signal is not restored after the proposed operations.
The findings led to the following conclusions. Imitating the imposition of a real threat for robotic systems, which are controlled by radio. The efficiency depends on imposing simulation time coincidence clock periods and interference signal at the demodulator input. Detect simulation can impose on the emergence of wasps oscillations at the receiver input. The developed method is an effective measure to combat the structural interference. Further research directed at the development of automatic decision-making procedures.

Neural Network Modeling of the Formation of Cluster Structures on the Basis of the Networks Art

In the article the peculiarities of clustering continuous data stream using neural networks the family of Adaptive Resonance Theory (ART). These neural networks are able to generate stable clusters by self-organization in response to arbitrary sequences of input patterns. ART neural network creates clusters dynamically in processing different input signals. It is able to adjust their size (number) depending on the complexity of the incoming data set.
ART Networks retain plasticity necessary to explore new images at the same time prevent forgetting previously stored images. To date, developed several kinds of neural networks based on adaptive resonance theory, in particular, the network ART-1 and ART-2, ART2-A, Fuzzy ART, etc. However, despite the similarity of the basic principles of operation of these networks, in the literature there is no unified approach to the description of their operation and training.
The aim of the study is to construct a universal generalized model of work of an arbitrary network ART family. In addressing the specific problems of clustering using this model, you need to choose the type of ART network (depending on the selected data structures) and generate content presented algorithmic steps. The article details the implementation of the steps discussed in the model for two different networks ART: ART-2a and Fuzzy ART using continuous input vectors. Each of these methods is largely parameterized, so the authors also proposed algorithms adjust the values of each of the parameters of these networks.
Keywords: neural network, stability-plasticity dilemma, adaptive resonance theory, clustering data stream
