In this article, the perspective methods of milling of tooth gears by disk cutters with the nonlinear coordination between feeding movements are presented. Besides, the algorithm of the contour calculation of sophisticated reconciled movements of a tool and a gear blank is described. © Published under licence by IOP Publishing Ltd.

In this paper, we consider the construction of binary classifiers ensembles on the basis of unnormalized form of ANFIS models. We notice training performance boost due to simplified model structure. In addition, the unnormalized ANFIS architecture provides the ground for effective task parallel decomposition of training procedures. © 2017 The Authors.

We consider certain types of convolution equations on distinct canonical domains in a discrete space. For describing solvability picture for such equations we introduce a special kind of a multidimensional Riemann boundary value problem. Key point of this studying is the concept of a periodic wave factorization which admits to obtain solvability conditions for these equations. Earlier the author has studied a half-space case, but now itiis possible to consider other canonical domains like cone in a multidimensional discrete space. © 2016 Author(s).

We introduce a discrete pseudo-differential operator in an appropriate discrete functional space and study the invertibility properties for such simplest operators in certain canonical domains of an Euclidean space. We construct special projectors for studying these operators according to a type of canonical domain and show how these operators are related to special boundary value problems for holomorphic functions of several variables. © 2017 Author(s).

The parameters and conditions defining liquid degasification upon ultrasonic treatment have been considered. Ultrasonic treatment has been applied to F-40 elastic polymer composite, and the effect of the ultrasonic-field parameters on the degasification efficiency is shown. © 2017, Pleiades Publishing, Ltd.

Piezoelectric immunosensors on the basis of homologous and group-specificantibodies have been developed for detecting penicillin G, ampicillin, and the total content of penicillin antibiotics. The receptor coating of the sensor was obtained by the immobilization of penicillin G or ampicillin hapten-protein conjugates on the polypyrrole film obtained by electropolymerization and activated by glutaraldehyde. The affinity constants and the cross reactivity coefficients have been calculated. This made it possible to estimate the affinity and specificity of the polyclonal and monoclonal antibodies used. The calibration curves are linear in the range of concentrations 2.5-250.0 ng ml-1 (penicillin G), 2.5-500.0 ng ml -1 (ampicillin), and 1-500 ng ml-1 (group of penicillin). The limits of detection are 0.8 ng ml-1, 3.9 ng ml-1, which are lower than MRL, established for penicillin antibiotics. The sensors were tested in detecting penicillins in milk, pork, beef, liver. © 2013 Elsevier B.V.

Genetic algorithm is an emerging technique used in engineering design activities to find an optimized solution which satisfy a number of design goals. Nonlinear direct method of goal search use successive linearization techniques, which are sensitive to the chosen starting solution and quality of the objective function. The proposed technique can solve programming problems having non-convex regions, which are usually avoided in classical optimization problems. The efficacy of the proposed novel method is demonstrated by solving a number of test problems. The results suggest that the proposed method is effective and represents a practical tool for solving sheet forming problems. Copyright © Taylor & Francis Group, LLC.

A piezoelectric immunosensor on the basis of electrogenerated polymer for detecting trace quantities of chloramphenicol, a drug which is used in veterinary for treatment and prevention of infectious diseases, was developed. The detection was conducted in a competitive format with the use of hapten-protein conjugate and monoclonal antibodies. The limit of detection is 0.2 ng ml -1, the calibration curve is linear in the range of concentrations 0.5-100.0 ng ml -1. Chloramphenicol was detected in food (meat, milk, egg, honey). © 2011 Elsevier B.V. All rights reserved.

In the paper, we discuss a role of quantum calculus, "differential calculus without taking limits" as a discrete analog of continuous mathematical analysis oriented on information technologies. We studied distinctive calculi that are alternative to quantum calculus and relate finite discriminators of values of an argument with finite discriminators of values of a function at their different combinations. © Pleiades Publishing, Ltd., 2011.

The analysis at nano-scale is important for the modeling of plastic deformation and its structures. We reviewed algorithms at nano-scale using FEM and presented a solution for modeling of such processes and corresponding algorithms. Also, we studied dislocations and avalanches in the deformed body, how they affect the quality, and methods to decrease their affluence on the product. For meshing of the model proposed method is to relate particle size and mechanical properties, which is investigated in the context of plastic deformation. Damage models presented in the paper can be proved useful for the production modeling and manufacturing. Modeling of buckling and plastic deformation proved to be useful to study the phenomenon and can be optimized with the proposed methods. Numerical verification using test benchmarks were conducted to demonstrate flange buckling, its particle measurements, and avalanches in the deformed part to validate propositions. © 2012 Published by Elsevier Ltd.
