A fundamental solution of topical problem for economic, social and technological future of Ukraine and the world is proposed. The problem lies in the elimination of corruption through the formation and implementation of the state program Creation of Cyber Physical Space for Digital Monitoring Technological Processes and Optimal Resource Management in order to Achieve Socially Important Goals. The cyber technology for human-free managing social resources (staff and finance) includes two cloud service: 1) the distribution of government contracts and finance between the structures, undertakings and entities, based on competition of their competence matrices for a given metric; 2) allocation of staff vacancies in scalable social groups based on competition of the competence matrices of applicants for a given metric. The competence metric is a measuring method of the distance between objects or processes based on the use of the parameter vector that defines the space or a competence matrix of a person or social group in real time. A competence matrix is a model of integrated activity and skills of a person or social group at a given metric and time interval. As an alternative solution of the problem it is considered a cyber physical system for managing human and financial resources (Cyber Social Systems - CSS), as a scalable cloud service, available to the social groups, government agencies, private companies and private individuals; it provides lifelong monitoring competencies of corresponding subjects in real time in order to carry out cyber staff management through appropriate career, moral and material incentives according to the results of their constructive activity. The cyber social system is focused on the total destruction of the corruption in the actions of managers at all levels by eliminating the subjectivity in the management of human and financial resources on the basis of the transfer of the official functions to independent cloud cyber service. The system consists of two interacting components: 1) accumulative monitoring of all kinds of human (social group) activity that generates a competence matrix in real-time; 2) the optimal management through career, moral and material incentives of individuals and social formations based on the analysis and rating of the corresponding competence matrices. A cyber system is based on the use of the following technologies: Big Data, Internet of Things, Smart Everything, parallel virtual processors and focused on serving individuals, government agencies and companies. For each subject two unique metrics of competencies are generated: 1) the gold standard of indexes for each category of professional activity; 2) the current competence matrix of the subjects filled in the process of their life, which are ranked by metrical comparison or evaluation of the results of work with standard or better values.

In VANETs, there are many applications that use broadcast communication as a fundamental operational tool, in disseminating information of interest to other road users under the umbrella of both safety and entertainment applications. Recently, the probabilistic broadcasting scheme is suggested as an efficient broadcast approach. Although a number of probabilistic schemes found in the literature, they still suffer from a high level of rebroadcast redundancy, which often leads to the Broadcast Storm Problem (BSP). Thus, in this paper a new efficient probabilistic broadcast scheme is developed, to target both achieving a high delivery ratio and reducing broadcast redundancy. Using simulation experiment, we compared the performance of the proposed scheme against the recent well known probabilistic schemes and our results confirm the superiority of our scheme over existing schemes in terms of key performance metrics, namely Reachability (RE) and Saved Rebroadcast (SR).

The main innovative idea of the proposed cyber physical system is step-by-step transfer of traffic lights from the ground to a virtual cloud space for vehicle management, equipped with a mobile gadget or computer, which displays on the screen map, route, coordinates of the road user and real traffic signals. The aim of this paper is to propose and discuss the formal modeling and technical realization of such cyber-physical system. A set of innovative technologies to address the social, humanitarian, economic, energy, insurance, crime and environmental problems through the creation and application of cloud-based digital traffic monitoring and management is developed. All these technologies and functional components are integrated into the system automaton model of cyber physical system for interaction between an infrastructure cloud of exact monitoring and digital control and vehicle gadget or computer.

Wireless Sensor Networks (WSNs) involve top potential technologies that will dramatically change the way of human living and working. Many scientific, industrial and environmental applications require real time information related to physical events like pressure, temperature or humidity. In the past the only way to transfer the sensed data to control center was through cumbersome, costly wires. But recent advancement in wireless networking enables WSNs to communicate the sensed real time event data wirelessly. WSNs have capabilities of sensing, processing and communicating which make them most suitable for monitoring different oil and gas industries upstream, midstream and downstream operations which help to increase production, decrease the accidents, maintenance cost and malfunctioning. The contributions of this paper are threefold. First, we highlight various characteristics of both WSNs and Oil and Gas Industrial environment. Second, we present major requirements of Oil and Gas industrial operations in the three sectors upstream, midstream and downstream. Third, we present the important issues and challenges specific to Oil and Gas industrial environment which affects the working and efficacy of WSNs. These issues and challenges should be considered by the researchers and developers who are planning to design a WSNs based solution for Oil and Gas monitoring.

Memory-driven computing for the design and test of digital devices is considered. One of the possible solutions to the problem of design and test theory and methods of quantum memory-driven computing on the classical computers for their subsequent application in all fields of human activity is proposed. Engineering-focused definitions of computing types are presented, including quantum one, which leverages the superposition and entanglement notions, and also memory-driven computing. The necessity of joint and parallel solving the problem of the creation of a market-accessible quantum computer and development of quantum-focused applications and cloud services is explained. Examples of quantum memory-driven design and test of digital circuit fragments are presented. A method for synthesis and minimization test for the black-box functionality, based on a qubit derivative matrix and sequencer for searching a quasioptimum coverage, is proposed.

Matrix method for quantum diagnosing functional failures and stuck-at faults in software or hardware units is proposed. It is based on qubit data structures comprising diagnostic information, which allows significantly reducing the computational complexity of the simulation and diagnosis due to the introduction of parallel logical operations on the matrix data. The quantum method for fault-free simulating digital units with the possibility of online repair of digital system components is presented. It is characterized by significantly improved performance due to addressed processing procedure of the functional primitives, defined by Q-coverages.

Low Power and Lossy Networks (LLNs) have a crucial role in the Internet of Things (IoT) paradigm. For the IPv6 Routing Protocol for LLNs (RPL), two objective functions (OF) have been standardized so far, namely (Objective Function zero (OF0), and the Minimum Rank with Hysteresis Objective Function (MRHOF). However, these particular objective functions are used to build a topology where bottleneck nodes may suffer from an excessive unbalanced traffic load. As a result, a part of the network may be disconnected as the energy of the overburdened preferred parent node will drain much faster than other candidate parent nodes. Thus, in this paper, we propose a new objective function that balances the number of children nodes for the overburdened nodes to ensure node lifetime maximization. To implement this OF, we amended the DIO message format. By using a new utilization technique, we also mitigated any potential extra overhead. Finally, a new RPL metric has been introduced to balance the traffic load over the network. Simulation experiments have been conducted to examine the performance of our new approach. Collected results corroborate the superiority of our objective function over the existing ones in terms of lifetime, power consumption and packet delivery ratio.

A cyber physical system for smart cloud traffic control is proposed. It is an intellectual (smart) road infrastructure for monitoring and control of traffic in real-time through the use of global systems for positioning and navigation, mobile gadgets and the Internet in order to improve the quality and safety of vehicle movement, as well as for minimizing the time and costs when vehicles are moved at the specified routes. The main innovative idea is step-by-step transfer of traffic lights from the ground to a virtual cloud space for vehicle management, equipped with a mobile gadget or computer, which displays on the screen map, route, coordinates of the road user and real traffic signals. A set of innovative technologies to address the social, humanitarian, economic, energy, insurance, crime and environmental problems through the creation and application of cloud-based digital traffic monitoring and management is developed.
