We achieved a CT(ozone concentration(ppm) X exposure time(min) )value of 60, which can inactivate coronavirus from 1/10 to 1/100 by operating for 24 h at an appropriate ozone concentration (less than 0.1 ppm) using feedback control in the previous report. In this system, the only way to reduce the ozone concentration is the decomposition reaction of ozone in the natural world, and it was not possible to cope with the rapid increase in ozone. In this study, we investigated the reduction of ozone concentration using hydrogen. As a result, it was clarified that the concentration of ozone rapidly decreased even with about 1/100 of hydrogen’s explosion limit (about 4%).

Using the Sigfox network, one of LPWA (Low Power Wide Area), and the Internet, we developed a temperature, humidity, pressure, and Internet of Things devices with different sensors to measure various physical data. It is much simpler to work with weather data when using OpenWeatherMap’s widely recognizable weather products. In this study, OpenWeatherMap’s meteorological data were captured every 15 minutes using are Sigfox communication, which is one of LPWA. These data were transferred to ThingSpeak using MATLAB analysis and time control of ThingSpeak.

The idea of creating and using digital twins has been strongly influenced by the process of integrating artificial intelligence methods with big data analytics of data from Internet of Things (IoT) devices. The concept of “Digital Twin” has become increasingly influential and culminating in the field of CPS. The main objective of the study is to define the basic requirements to the digital twins for cyber-physical system and based on the different definitions and components of digital twins, to summarize and analyze approaches, methods and tools used for their development. This analysis should serve as a basis for the development of a methodology for creating digital twins for cyber-physical manufacturing systems in the process industry.

An integrated smart home system for monitoring and management of the elements of the working environment or at home in Home Assistant platform and is integrated with a voice assistant (Google Assistant) has been developed. It allows monitoring and control of various parameters of the environment, determination of geolocation, tracking the state of the connected devices, provides ascertainment of conditions or constraints during the implementation of logical algorithms or actions, etc. The developed integrated system solves the problem of using various interface applications, communication protocols and standards by integration of all its elements in one Application Programming Interface (API) and simultaneously expanding its scope through integration with a voice assistant (Google Assistant). The development of a dataset of interoperable rules integrated in the Smart Home/Office system should be done function by function. This paper is directed toward the sequential development of integrated remote-control Smart Home/Office systems by adding additional functionality to the already developed integrated system.

The advancement in Information and communication technologies has created conditions for using these technologies in many applications including the industry ones. Robotics has been traditionally present in industries, especially in manufacturing. Development of cyber-physical systems, artificial intelligence, smart sensors, Internet of Things, and other relevant technologies enabled certain transformation in the field of robotics which resulted in new robotics concepts that lead towards smart factories and fulfilment of Industry 4.0 requirements. This paper deals with some of these concepts such as cloud robotics, Internet of Robotics Things and collaborative robotics giving their main characteristics and possibilities of application in Industry 4.0 domain.

The Internet of Things (IoT) concept is evolving rapidly and influencing new developments in various application domains, such as the Internet of Mobile Things (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Sys-tem of Things (ASoT), Internet of Autonomous Things (IoAT), Internet of Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc. that are progressing/advancing by using IoT technology. Artificial intelligence (AI), robotics, machine learning, and swarm technologies will provide the next phase of development of IoT applications. In this paper, the areas of application of internets of robotics things are given.

Modern industry requires intelligent development of the product throughout its entire life cycle-from concept to recycling. These intelligent products (Smart Products) have information about their production processes, quality management, future application and recycling. They support active manufacturing processes (when will be produced, with what parameters, with what materials should be produced, when, what kind of modifications, etc.). Under these conditions the management of quality have to meet new requirements imposed by the fourth industrial revolution is discussed in this article.

The paper is devoted to research of convergent technologies as a key factor in solving global problems in the new industrial revolution. It is shown that the concepts of the new industrial revolution, which today are widely used by Western scientists, also envisage the convergence of sciences and technologies and the creation of advanced manufacturing technologies on their basis. It is only possible to launch Industry-based trends in Industry 4.0 through the introduction of advanced manufacturing technologies based on convergent technologies. The approach to the periodization of scientific and technical development, which links the economic, technological and socio-political factors of development, as well as characterizes the structure of the sixth technological structure, the vision of the content of the new industrial revolution based on the organic combination of convergent NBIC-technologies with key factors, as well as approaches to solving global mankind issues are proposed.

Today Industrial Enterprises are facing the challenge of the 4th Industrial Revolution. Steam Power, Henry Ford’s Assembly Line, and Proliferation of Coal-based energy etc. – each of these developments in the evolution of manufacturing fundamentally changed the way products were manufactured and the way manufacturers moved products from factory to the customers. The present paper discusses the term “Industry 4.0” and its main characteristics, as well. Furthermore, a theoretical framework for evaluation the key technologies and concepts with respect to their impact on the production engineering and management. Also this paper discusses and some given arguments why manufacturers need to make changes in their traditional view of the functioning of the production system in term of “Industry 4.0”.

The present paper presents the development of the VeloCity project which seeks to promote the cycling as a part of daily transport and recreation. One of the main objectives is integration of bicycle into urban multimodal mobility and urban planning and other relevant policy sectors where cycling plays an important role. For obtaining the goal a survey is conducted locally and via Internet and the results are analyzed; user requirements analysis is conducted through information resources study, and a number of user scenario are defined.

Basic parameters of a smart bicycle are defined through summarizing the most interesting and useful user scenarios, applicable for more safety, flexible and comfortable cycling. The user scenarios are the base for hardware and software development for a smart bicycle, selection of proper technologies, building of a prototype and experimental platform for the smart system testing.

The idea of smart cities is timely considering that urbanisation is inevitable. While smart city as a concept has gained popularity over the past few years, there is vagueness in the definition, as multiple aspects including governance, public transport and traffic, waste management, entertainment and safety among others, need to be considered.

Europe is among the most urbanised regions on the globe. It is estimated that by 2020 around 80% of Europeans will be living in urban areas, in several countries the proportion will be 90% or more. As we continue to magnetise towards urban hubs we need smart cities – places where networks and services are made more efficient with the use of digital and telecommunication technologies for the benefit of inhabitants, businesses and the environment. The EU is trying to ensure that smart solutions for cities can be explored, implemented and replicated.

The present paper defines some of the aspects of the smart city as safety as well as specific models of smart and safe city will be discussed.

Due to increasingly competitive is required the companies to provide personalized products and services.
