Yu Shunin1, S Bellucci2, T Lobanova-Shunina3, Yu Zhukovskii1, N Burlutskaya4, V Gopeyenko4
Fundamental electromagnetic and electromechanical properties of CNTs, graphene nanoribbons (GNR) and nanofibers (GNF), CNT- and graphene-based aerogels (CNTBA, GBA), CNT- and graphene-based 3D-nanofoams and carbon-based polymer nanocomposites are essential for various nanotechnology applications, e.g. for the engineering of new classes of ultra-light, highly conductive nanomaterials with exceptional mechanical strength, flexibility, and elasticity. These nanomaterials provide the basis for unique nanoelectronic devices and nanosensors. Particular properties of carbon-based nanoporous systems in dependence on porosity extent, morphology and fractal dimension allow finding practically useful correlations between their mechanical and electrical properties. Electromagnetic properties of CNTs and GNRs nanostructures with functionalized atomic groups and their various interconnects with the essential concentration of ‘dangling bonds’ are very sensitive to local external perturbations. The induced changes of local electronic density of states lead to the correlated changes of current and spin states. Models of nanocarbon spintronic devices are developed as memory nanodevices, particularly, based on magneto-resistance phenomena. Models of nanocomposite carbon-based materials and nanodevices are proposed.

Photocatalytic efficiency of SrTiO3 nanowires: ab initio modeling
Yu F Zhukovskii1, R A Evarestov2, A V Bandura2
First principles periodic calculations based on the density functional theory within the localized atomic orbital approach (DFT-LCAO) using the hybrid exchange-correlation potential PBE0 have been performed in order to simulate the structural and electronic properties of both non-stoichiometric and stoichiometric -oriented four-faceted SrTiO3 (STO) nanowires (NW) of cubic structure. Their diameters have been varied from 0.3 up to 2.4 nm with a correspondence to a consequent change of NW cross-section from 2x2 to 5x5 extension of the lattice constant in bulk. Energetic stability of STO NW (both non-stoichiometric and stoichiometric) has been found to be increased with the decrease of their formation energies together with the increase of NW diameter. The electronic structure calculations have shown that the width of band gap is changed in STO NWs of different structural types as compared to that in bulk being consequently reduced with the growth of NW diameter although character of such a decrease depends on morphology of nanowire. Analysis of these changes shows that non-stoichiometric TiO2-terminated and stoichiometric strontium titanate nanowires can be quite promising candidates for further applications in photocatalytic processes under solar irradiation whereas SrO-terminated nanowires are rather not suitable for this purpose.

Emma K. Shidlovskaya
Applicability of cluster embedding method with non-orthogonal wave functions for theoretical study of processes in nanodevices is studied. Processes in nanodevices are treated in the frameworks of quantum transport theory. We demonstrate that our cluster embedding method is compatible with DFT Kohn-Sham method and quantum transport theory based on time-dependent DFT. We conclude that quantum transport theory methods for electric current calculation may be applied if we use one-electron approaches with orthogonal and nonorthogonal wave functions. Possibilities of theoretical modelling of nanodevices beyond approaches based on one-electron approximation are discussed.

A Chesnokov, O Lisovski, D Bocharov, S Piskunov, Yu F Zhukovskii
In this theoretical study we compare atomic and electronic properties of titania nanotubes (NTs) with different morphology. Our first principles calculations have been performed using a modified B3LYP hybrid exchange-correlation functional within density functional theory (DFT). For periodic systems, we apply method of crystalline orbitals as linear combination of atomic orbitals (CO LCAO) implemented in the CRYSTAL code, while the NWChem code is used for MO LCAO calculations on non-periodic systems. In our study, 9-layered (001) anatase nanotube, an object of our earlier studies, is compared to various 6-layered (101) anatase nanotubes. Specifically, we compare their stability, formation energies, doping possibilities and dependence of band structure on types of dopant atoms (N and S as individual atoms or when introduced in pair). We also investigate how concentration of dopant atoms affects the band structure and discuss interactions between impurities. In order to reduce computational time and to be able to run more complex calculations in reasonable time, we investigate strategies for reducing size and dimensionality of our model, e.g., transition from a periodic model of a nanotube to its non-periodic cluster model as repeating NT fragment.

I Mihailovs, V Gopejenko
Human organism diagnostics based on the analysis of the signals generated by itself such as brain waves and voice signals in order to used them to control the objects, and the development of the intellectual systems that would be capable to do this currently is one of the most important tasks of the modern bioinformatics. To solve this problem it is necessary to relate the investigated part of the electroencephalogram to one of the possible classes – signals with significantly larger general statistical properties.
This task can be solved with the help of the neural networks that are able to compare their own output signal of the certain controlled actions with the given initial educational signal and to perform self-tuning – automatic fitting of the internal weight coefficients in order to minimize the discrepancies between the factual output signal and educational signal.

The approach adopted by Fisher for pattern recognition (classification) was to find a linear combination of the variables that separates the two classes as much as possible. That is, we seek the direction along which the two classes are best separated in some sense. It should be noted that this direction does not provide us with an allocation rule, merely a mapping to a reduced dimension (actually one dimension in the two-class situation) in which discrimination is in some sense easiest. Fisher’s classification (allocation) rule based on distance is one of the most widely used classification rules for two sample multivariate normal data. A key assumption for the validity of its use is that the variance matrices of the two normal populations are equal. Since this assumption may often be violated, it is of interest to propose a classification rule when the variance matrices are not equal. Therefore, in this paper, the classification rule based on minimization of misclassification probability is proposed. A numerical example is given.
In practice, we often are in need of analyzing input data samples, which are not adequate for Fisher’s recognition (classification) rule (i.e., we deal with non-standard situations, such that the distributions of the groups are not multivariate normal or covariance matrices of those are different or there are strong multi-nonlinearities). This paper proposes a novel approach to pattern recognition (classification) based on minimization of misclassification probability. The approach does not require the arbitrary selection of priors as in the Bayesian classifier and represents the novel pattern recognition (classification) procedure that allows one to take into account the cases, which are not adequate for Fisher’s classification rule. For the cases, which are adequate for Fisher’s classification rule, the proposed approach gives the results similar to that of Fisher’s recognition (classification) rule. For illustration, a numerical example is given.
Novel approach to dose estimation in drug development
N A Nechval1, K N Nechval2
Identifying the ‘right’ dose is one of the most critical and difficult steps in the clinical development process of any medicinal drug. Its importance cannot be understated: selecting too high a dose can result in unacceptable toxicity and associated safety problems, while choosing too low a dose leads to smaller chances of showing sufficient efficacy in confirmatory trials, thus reducing the chance of approval for the drug. The optimal dose is the dose that gives the desired effect with minimum side effects. The dose of a drug is of course ‘optimal’ only for a given subject, but not necessarily for any other. In view of this the objective of a dose-finding trials is not to determine a single fixed dose for use in the early phases of clinical trials or in medical practice, but to determine an interval of doses within which there is a stated degree of confidence that the defined, acceptable therapeutic response and the frequency of adverse reactions will lie above and below, respectively, certain acceptable predetermined levels. If the subject samples used in the dose finding studies adequately represent the subject population for which the drug is intended, the interval of doses so defined can be applied to the subject population as a whole. In this paper, we propose the novel approach using the maximum likelihood principle in order to estimate the maximal tolerated dose (MTD) and minimal effective dose (MED) on the basis of k samples of subjects, which are grouped in a simplest way. The necessary and sufficient conditions for the existence and uniqueness of the maximum likelihood estimator are derived.

Computing with words for user-specific fuzzy retrievals
A Rakhmetullina, P Shamoi
The aim of this paper is to demonstrate the necessity of using fuzzy sets and logic in the user-specific fuzzy retrievals processing. User-specific retrievals are widely used in plenty of web-applications such us online shops, search engines and others. Most of the user-specific retrievals now is realized by searching in limited conditions. This leads to lose of some portion of relevant results that was close but not in certain constraints. Also often users are not prepared or do not have precise requirements and need some tool to make request with blurred conditions. Fuzzy classification can be very appropriate in this case, because it is more likely to the way in which people think and form their thoughts. One of the advantages of discussing method is that it is compatible with relational databases. We illustrate proposed method on the example of appartment searching system. Opportunity to send a query to the system in a natural language, like show the list of not very expensive average size apartments near or not very far from the center, is a most significant benefit of using this approach and cannot be done by standard mechanisms.
In this paper possibillites of aggregational values calculation is considered. Aggregational values are the main element of multidimensional operative analytical processing. The main reason of using parallel computation systems in data processing is to increase productivity level. Although, parallel computation systems cannot be used in processing all data types.

In this regard, data decomposition for formation aggregational values in parallel computation systems in data operative analyzing is considered in this paper. In order to identify dependence between data during the process of decomposition Bernstein's conditions are used. At the same time implemented course calculation of n-dimension from 1-dimension and parallel computation of course interactions will also be considered.

First, let's denote the object of our study. What is the test? And how can we measure the level of doubt test during testing?
Testing in general scientific sense is a brief standardized test aimed at obtaining a compressed period of time the most essential information about the symptoms of this particular object in order to establish his presence or severity of a particular property or quality. Testing is now used in various fields: medicine, psychology, and programming. But more often the word "test" is associated with the method of testing students' knowledge. Traditional pedagogical tests are a list of questions and tasks of different difficulty levels. The following types of jobs:
- With a choice of one correct answer (closed);
- With a choice of several correct answers;
- With a choice of wrong answer;
- The establishment of conformity;
- The establishment of the sequence;
- Tasks that require their own write response (open).
Depending on the complexity of the issue, the answers are assessed at different points.
Testing puts all participants on an equal footing. In one side this method of examination more equitable than the traditional test of knowledge. On the other hand, there is an element of chance, where the student can just guess the answer. And this is the purpose of the study, that is, to minimize the degree of doubt, and improve the quality of education.

The study logical methods of modelling the behaviour of hybrid systems
A Altayeva, Zh Sarsenova
A hybrid system is a dynamic system that exhibits both continuous and discrete dynamic behavior – a system that can both flow (described by a differential equation) and jump (described by a difference equation or control graph). A hybrid system has the benefit of encompassing a larger class of systems within its structure, allowing for more flexibility in modelling dynamic phenomena. In general, the state of a hybrid system is defined by the values of the continuous variables and a discrete control mode. The state changes either continuously, according to a flow condition, or discretely according to a control graph. Continuous flow is permitted as long as so-called invariants hold, while discrete transitions can occur as soon as given jump conditions are satisfied. Discrete transition may be associated with events.

Juris Roberts Kalnins, Natalja Jarohnovich
The aim of the research paper is to create technology transfer process management model, visual modeling tool in Vensim environment, to demonstrate the basic operation of dynamic models, as well as to prove the practical use of this tool usefulness. In this work there was considered the principles of systems thinking approach to technology, transfer processes and channels, there was discussed technology transfer raising role in the competitiveness of the company, there was made an analysis of the situation in Latvia, in the result the activity of Vensim environment was set up technology transfer management of a dynamic model. After compiling and analyzing the information, were inferred conclusions and proposals. Successful management of technology transfer model is needed to achieve a balanced interaction of three components: basic science, management and technology transfer industry, where one of the prerequisites is immediate fundamental science support increase (rather than the national budget of the EU funds). Results of this research can be used for Latvian technology transferring and innovation system (model) creation and delivery. Also this work might be helpful for innovation specialists, organizations dealing with transformation of technologies, as well as for everybody interested in technological absorption capacities and technology transfer.

Education software on robotics programming
Nayden V Nenkov
This article discusses the issue of selection of suitable software environment for programming the robots needed for university studies. Educational robots are two types of Lego Mindstorms NTX2 and Lego Mindstorms EV3.
This paper considers algorithms for concurrency control in Distributed database (DDB) systems. Below are the simulating models of the implementation of two-phase locking (2PL) in DDB. From four types 2PL in DDB (Centralized 2PL, Primary copy 2PL, Distributed 2PL and Voting 2PL) is viewed Primary copy 2PL, as this protocol is a "transitional" protocol of Centralized 2PL to the Distributed 2PL. The paper describes specifically the simulations of two-version 2PL and 2PL with integrated timestamp ordering mechanism. In concurrency control method 2PL may take place deadlocks of the transactions. Therefore, in the modelling algorithms described here are integrated algorithms for deadlock avoiding: two-version architecture of database and timestamp ordering strategy “wait-die”. There are also presented, the results of the simulations of these two variants of the 2PL method at different scales of the networks for the transmission of data and at different intensities of inflow transactions. Modelling algorithms are developed by means of the system for simulation modelling GPSS World Personal Version.
Balanced geometric model and common scenarios for uplink power control in industrial wireless networks
Teodor Kalushkov, Oleg Asenov
Industrial networks now are trying to implement wireless technologies, following the tendencies in communication networks. This task is complicated because of the nature of the industrial environment. Wireless connections can hardly achieve the same stable quality of service (QoS) parameters as traditional cable ones. Interference is one of the reasons for that and should be developed effective solutions for its reducing in order to maximize the throughput of the wireless media. Balanced geometric model, which reduces interferences between endusers and access points, is proposed. It is based on Nash Equilibrium Theory and gives opportunity to control the output power of wireless devices in optimal way. The use of vectors in the model helps to analyse in details, impacts between the neighbour points – their power and direction. At the end, there is a sample for using balanced geometric model in industrial network.
