ISBN 978-5-02-040757-2.The first volume of the book includes papers devoted to three main areas of research in the field of synthesis of self-checking discrete systems: study of features of classical sum codes (Berger codes), modular sum codes, as well as their modifications proposed by the authors of the articles; study of features of codes for which check bits are obtained using convolutions modulo М = 2 of a part of data bits (polynomial codes and classical Hamming codes); research of the Boolean Complement method for organisation of self-checking discrete systems based on redundant binary codes. Materials are provided on detailed characteristics of error detection in data bits of redundant binary codes under the condition of errorfree check bits, descriptions of methods for constructing previously unknown modified sum codes and features of methods for synthesizing self-checking discrete systems based on binary redundant codes.The second volume of the book includes papers in the field of constructing binary sum codes weighted bits and transitions between bits occupying adjacent positions in data vectors of code words, as well as the results of studying their characteristics and methods of synthesising coding equipment. The issues of application of features of codes in organisation of self-checking discrete systems are considered. The reader will find on the pages of this volume materials on detailed characteristics of error detection in data bits of weight-based sum codes provided that the check bits are error-free, descriptions of methods for constructing previously unknown weight-based sum codes and features of methods for synthesising self-checking discrete systems based on them.The book can be useful for developers, researchers and engineers working in the field of technical diagnostics of discrete systems and synthesis of systems with fault detection, as well as students studying computer science, computer technology and automation.

CAMPUS MITHRA: Design and implementation of voice based attender robot

A robot is a machine which is programmed by a computer and the movements and functions of which are controlled by an external or an embedded control. It has dynamic uses in all domains of life. A robot in a university setting can be used as an attender for passing circulars around instead of multiple attenders doing the task manually which is a cost and time consuming process. Parents often find it difficult to navigate through the unfamiliar university. In this paper, we have focused on a voice based attender robot with line following capabilities along with speech recognition that can be used at universities for a variety of purposes like passing around the circulars, interacting with parents and helping them navigate through the university through Spoken Natural Language. The main objectives of the proposed work is to reduce the burden of passing circulars, calling a student/faculty on the attender by designing a robot that is also competent enough to connect with human through spoken natural language such as English or Kannada, so that it interacts with parents who are new to the institution and do not know whom to approach. The main aim of this work is to introduce a robot that it is able to interact with human through the Spoken Natural Language. Here, the focus is on two languages; English and Kannada. This system uses a voice recognition module to recognize human voice and a voice playback module is used to reply back in either English or Kannada according to the user’s command. It can work in two modes, the voice recognition mode to answer to user queries or in line following mode to pass circulars, call student/faculty. In this way, the voice based attender robot finds its applications in the university setting. But it is not limited to only universities. It can also be further implemented in places like railway stations, bus stations, big factories and other similar surroundings.

Research of Sensor Systems in Temperature Changes

Direction included in the technology of "Internet of Things" to analyze the working of sensor systems in extreme areas, that is the properties and features of embedded control systems based on them, to identify the main problems of operation and features of sensors in smart - systems. The article considers the main types of sensors used in smart systems, the main alignments used in the design and creation of systems based on them, and experimentally evaluates the dependence of the speed of sound on air temperature.

A sampling-based approach for handling delays in continuous and hybrid systems

Delays in feedback dynamics of coupled dynamical systems arise regularly, especially in embedded control where the physical plant and the controller continuously interact through digital networks. Systems featuring delays are however notoriously difficult to analyze. Consequently, formal analysis often addresses simplified, delay-free substitute models, risking negligence of the adverse impact of delay on control performance. In this ongoing work, we demonstrate that for continuous systems such as delay differential equations, a major part of the delay-induced complexity can be reduced effectively when adding natural constraints to the model of the delayed feedback channel, namely that it transports a band-limited signal and implements a non-punctual, distributed delay. The reduction is based on a sampling approach which is applicable when the above conditions on the feedback are satisfied. We further discuss the possibilities of lifting this method to mixed discrete-continuous dynamics of delayed hybrid systems and the open issues thereof.

Implementation of Attender Robot in Campus

A robot is a machine that has been programmed by a computer and has external or embedded control over its movements and activities. It has a wide range of applications in all aspects of life. A robot can be employed as an attender in a university setting to distribute circulars around instead of numerous people doing it manually, which is a costly and time-consuming method. The unfamiliar campus might be challenging for parents to navigate. In this review paper, we focus on a voice-based attender robot with line-following skills and speech-to-text recognition that may be utilized for several tasks at universities, such as passing out circulars, engaging with parents, and assisting them with navigation. The goal of this work is to create a robot that can communicate with humans using Spoken Natural Language. Two languages will be highlighted here: English and Kannada. This system employs a module that recognizes human speech, which is then processed and used to act or respond to the user's order. In this fashion, the voice-activated attender robot can be used in a university setting. However, it is not confined to universities. It can also be used in locations such as train stations, bus stops, large factories, and other similar settings.

A DIN-RAIL BASED MODULAR DESIGN FOR CONTROLLING OBSERVATORIES AND TELESCOPES

In this paper we describe a multi-functional electronics design suitable to implement versatile embedded control functionalities, especially to drive autonomous telescope systems. This system of ours is a daisy-chained series of electronics having a DIN-rail compatible form factor, where each of the modules support all of the functionalities related to inter-module communication, autonomous computing and supporting physical connection and drivers to external interfaces.
