Hardware-Software Im­plementation of 1-Wire Interface Based on STM32 Microcontroller

Abstract

This paper presents an implementation of 1-Wire communication inter­face based on STM32 microcontroller with the usage of hardware timer. Im­plemented low-level library uses minimum of MCU resources, has address search functionality and can be applied for polling sensors in wired networks based on this interface.

1+1-Dimensional Yang — Mills Equations and Mass via Quasiclassi­cal Correction to Action

Abstract

Two-dimensional Yang — Mills models in a pseudo-euclidean space are considered from a point of view of a class of nonlinear Klein — Gordon — Fock equations. It is shown that the Nahm reduction does not work, another, novel choice is proposed and investigated. A quasiclassical quantization of the models is based on Feynmann — Maslov path integral construction and its zeta function representation in terms of a Green function diagonal for an aux­iliary heat equation with an elliptic potential. The natural renormalization use a freedom in vacuum state choice as well as the choice of the norm of an evolu­tion operator eigenvectors. A nonzero mass appears as the quasiclassical cor­rection, that is expressed via hyperelliptic integral.

Development and Research of Properties of Mail Exchange Protocols Inside a Hybrid Cloud with Two Re-Encryption Based on Hess Pairing

Abstract

In this article we describe Hess pairing on elliptic curves and create its computational algorithm. Main purpose of this article is creation and proper­ties overview of mail-exchange protocol inside hybrid cloud with two re-encryptions, based on this pairing. Also, we describe an authentification algo­rithm, used in this protocol.

Auto­matic System for Determining the Angles of Scoliotic Deformity of the Human Spine

Abstract

Scoliosis is a common disease among children and adults. A standard method for assessing the severity of scoliosis is to measure the Cobb angle. However in some cases the Cobb angle may not be clinically indicative. More­over, the measurement process is fraught with errors caused by the subjectivi­ty of setting key points at the first measurement stage. The article describes the developed system for measuring the scoliosis angle, based on the use of ar­tificial convolutional neural networks and subsequent algorithmic processing. The objective of the developed program is to measure the angles of scoliotic de­formation of the spinal column.

Bundles of Projective Normals of the Hyperband Distribution of an Affine Space

Abstract

It is shown that the H -distribution for each L-, L-, H-subbundles gene­rates three one-parametrical families of Norden internal normalizations in the 2nd order differential neighbourhood. Construction H-subbundle of the Fubini and Wilczynski projective nor­mals is given. Canonical bundles of 1st and 2nd kind normals are constructed for each L-, L-, H-subbundles of the H-distribution.

Implementation of a Software Signal Generator of Various Shapes Based on a Microcontroller of the STM32F10x Family

Abstract

This paper describes the principle of building an arbitrary waveform gen­erator based on the STM32F10x MCU family. This generator was successful­ly applied by the authors of the study in the development of the electostimula­tion device. Waveform generator allows to generate impulses of square, trape­zoidal, sawtooth and sinusoidal shape in a wide frequency range, creating minimal computational load on the core of MCU. Software signal waveform generator can also be applied in creating other electonical devices such as mo­tor drivers or can be used as laboratory signal source.

Analysis of the Pos­sibilities of Introducing Blockchain Technology in the Banking Sector

Abstract

The paper analyzes the main options for introducing blockchain technol­ogy in the banking sector. The foundations of the technology itself, its ad­vantages and limitations are considered. The option of introducing technology in the form of a combination of internal and external blockchains with the in­volvement of the resources of the regulator represented by the Central Bank of the Russian Federation is proposed.
