The polynomial spline collocation method is proposed for solution of Volterra integral equations of the first kind with special piecewise continuous kernels. The Gauss-type quadrature formula is used to approximate integrals during the discretization of the proposed projection method. The estimate of accuracy of approximate solution is obtained. Stochastic arithmetics is also used based on the Contrôle et Estimation Stochastique des Arrondis de Calculs (CESTAC) method and the Control of Accuracy and Debugging for Numerical Applications (CADNA) library. Applying this approach it is possible to find optimal parameters of the projective method. The numerical examples are included to illustrate the efficiency of proposed novel collocation *** Codes 45H05, 65R20 © 2021, CC BY.

We introduce the Piquasso quantum programming framework, a full-stack open-source software platform for the simulation and programming of photonic quantum computers. Piquasso can be programmed via a high-level Python programming interface enabling users to perform efficient quantum computing with discrete and continuous variables. Via optional high-performance C++ backends, Piquasso provides state-of-the-art performance in the simulation of photonic quantum computers. The Piquasso framework is supported by an intuitive web-based graphical user interface where the users can design quantum circuits, run computations, and visualize the results.

To search for new technical solutions when designing color measuring systems, we need a design object, i.e. to divide color measuring device into fragments, and solutions are sought for these fragments separately. At the first level of the partition, the color measuring device is divided into four main structural parts: the lighting, dispersing, electronic recording and computing devices.

We analyze smooth nonlinear mappings for Hilbert and Banach spaces that carry small balls to convex sets, provided that the radius of the balls is small enough. Being focused on the study of new and mild sufficient conditions for a nonlinear mapping of Hilbert and Banach spaces to be locally convex, we address a suitably reformulated local convexity problem analyzed within the Leray-Schauder homotopy method approach for Hilbert speces, and within the Lipscitz smoothness condition both for Hilbert and Banach spaces. Some of the results presented in the work prove to be interesting and novel even for finite-dimensional problems. Open problems related to the local convexity property for nonlinear mapping of Banach spaces are also *** Codes 46B20, 49J50, 52A41, 58C20 © 2021, CC BY.

In article the research of dynamics of change of electromagnetic parameters of the controlled special electric drives is conducted. Special electric drives are the controlled cascade electric drives of cylindrical and axial designs. The research of dynamics of change of parameters was executed to a basis of a method of electromagnetic transformation of energy and the theory of electromagnetic chains. As a result for new mathematical models of an electromagnetic system of the research electric drives parameters of the electromagnetic field of the closed round of one coil of an electric winding with electric current in a homogeneous environment are determined. The solved task is spatial as distribution of electromagnetic induction in a round of the set form of the electromagnetic coil is defined. The received conclusions of determination of electromagnetic parameters of cylindrical and axial electric motors of special electric drives allow to solve correctly problems of modeling, design and improvement of efficiency of the research electric drives and other electromechanical converters of energy of various designs. Results of a research are applicable for creation of the computer-aided engineering system of the research electric drives and the solution of problems of modeling and design. The conducted research allows to create electric drives optimum mass-dimensional and power indicators.

Effective application of Augmented Reality user interfaces is one of the challenging trends of industrial cyber-physical systems development and implementation. Despite reach functionality of modern AR devices (like goggles, head mounted displays or tablets) the problem of their comfortable and productive use is not completely solved yet. To cover this gap, it is proposed in this paper to implement a new paradigm of 'accented visualization' that allows adapting additional data presented by AR device according to the user's current interest, attention and focus. To provide such context driven functionality there was developed intelligent software based on eye tracking and capturing the user's focus in ontology as a knowledge base. Probation and testing of the proposed approach present 89 % of the solution efficiency. © 2018 IEEE.
