How close we are to the real Quantum Computer? Efficient Monte Carlo algorithms for Wigner Monte Carlo Method
Ivan Dimov

Abstract: In order to determine how close we are to the "Real Quantum Computer" we consider the following topics:

  • The Wigner formalism
  • The Wigner Monte Carlo method
  • The Signed Particle Formulation of Quantum Mechanics
  • Analysis of the Convergence
  • Benchmarks and Applications
  • The Many-body Wigner Formalism for Indistinguishable Particles
  • Fermions and Bosons
  • The Pauli Exclusion Principle
Extensive numerical experiments with Monte Carlo, quasi-Monte Carlo (QMC) and scrambled quasi-Monte Carlo algorithms based on Sobol sequences are performed to support the theoretical studies and to analyse the applicability of the algorithms to various classes of problems. Numerical tests illustrating main conclusions are run on massively parallel supercomputers. Some exciting results will be presented. Practical results showing stable and consistent nano-structure solutions for quantum computer devises are proposed and analysed.

IT impact on the labor market – professions to disappear and new ones to emerge
Avram Eskenazi

Abstract: Based on recent publications, the speaker will demonstrate the sustained trend in labor market polarization as a result of the turbulent development of Information Technologies (IT) and, more recently, of Artificial Intelligence (AI). There are two hypotheses already outlined about the future development of this polarization - a trend of attenuation and a trend of retention in the foreseeable future. The lecturer will launch and justify a third option - a gradual transition to a unipolar model. As a side effect a number of professions will gradually disappear, only to be replaced by new ones emerging.

Robots for Help of Pedagogy and Rehabilitation
Roman Zahariev
Co-authors: Nina Valchkova, George Angelov, Yasen Paunski, Aleksander Krastev

Abstract: The research of modern systems of engineering and service robotics aims to implement cost-optimized innovative approaches to build intelligent, robust and reliable robotic devices and technology systems that serve people's needs and create the conditions for a better quality of life for future generations. It is described experience for development, prototyping and using of Mobile Cognitive Robotic Systems designed for service and assistance to people with disabilities. At the same time, due to the intelligence of the robots created, it is possible to use them as educational learning tools, which is quite extensive worldwide widespread, yet it is rather limited in special education for the children with disabilities. It has been created a series of Service Mobile Robots type AnRI (Anthropomorphic Robot with Intelligence) to help disabled people as well as the elderly. These robots are also successfully used in the process of special education of children with needs. Simultaneously an anthropoid robot type Nao is also implemented in the training process. Experimental research has been carried out in the process of introducing robotic technologies in special education for children, youth and pedagogical specialists in the framework of the implementation of a project funded by the EC under the “Marie Curie” Program, Project H2020-MSCA-RISE-2017, ID No. 77720 "CybSPEED:" Cyber-physical systems for pedagogical rehabilitation in special education".

Computationally Intensive Tasks in Designing and Operating Distributed Cyber Secure and Resilient Systems
Todor Tagarev, George Sharkov

Abstract: The modern digitized society, economy and government increasingly depend on advanced sensor, information and control technologies. Communications and IT infrastructures become the backbone for the functioning of mass transport, energy generation and distribution systems, public administration, banking, water and food management, heavy industries and even for tracking the medical condition of certain groups of people.

While boosting effectiveness and efficiency, the massive incorporation of technological solutions introduces vulnerabilities, often exploited with malicious intent. The provision of safety, security and resilience of the evolving systems of systems poses a number of regulatory, procedural, technological and competence challenges.

This report examines the features of distributed systems for cybersecurity and, on that basis, elaborates general tasks in designing and operating such systems that are computationally demanding. These are: detection of cyberattacks and hybrid malicious activities; situational awareness, requiring fusion of information from diverse and disparate sources, visualization, and sense-making; decision-making, i.e. foreseeing possible evolution, devising and comparing potential courses of action, in particular with application of artificial intelligence; and cyber forensics, intelligence and attribution. In terms of technology – new methods like big-data analysis, high performance computing, AI and machine learning are not only providing new generation tools but influence significantly the design of such complex systems-of-systems with emerging complex behavior. Particularly demanding in terms of computational power is finding the balance between effectiveness and resilience of distributed systems of systems (connectivity, interoperability, info sharing, etc.) and the provision of agility and adaptation to the changing security and technological environment, including the challenges of detecting and reacting to the “unknown”.

How to integrate complex optimal data processing in information services in internet
Todor Stoilov

Abstract: Information technology implements its outcomes in development information services, which are available in virtual environments. As information services a lot of business entities operate offering e-shop facilities, virtually offering of business information, galleries, many others information services based on distribution of on-line important data. The increase of usage of information services insists the functionalities, offering by the information systems to provide complex treatment of the data. Thus additional and new business relations are identified and can be taken in consideration in managing and decision making in complex systems. Optimal treatment of data is a keystone for increase system functionalities in supporting the decision management. The presentation illustrates how to provide optimization functionalities in virtual information system. The software suits in such systems are outlined. An example, related to information service dealing with optimization of portfolio investments is given.

A pedagogical perspective towards ICT-based innovative educational technologies - case study on TeSLA Integration in e-assessment
Roumiana Peytcheva-Forsyth

Abstract: There are different perspectives for analysing the effectiveness of ICT-based technologies in education - technological, psychological, socio-psychological, methodological, pedagogical. It is the latter that seeks, defines and studies the intersection between other perspectives, which characterises the way in which specific technologies are integrated in a particular educational context. The pedagogical perspective reveals and defines the indicators for the successful integration of a certain innovative ICT-based technology in order specific educational objectives to be achieved with a specific group of learners on a particular topic. In other words, the pedagogical perspective refers to the “contextualised effectiveness” of the innovative educational technologies. The context itself defines how innovative is a particular technology or the way it is used. The presenter will discusses the pedagogical perspective in seeking the effective use of innovative ICT-based technologies in education. She will present an example of an integrated student authentication and authorship checking system in e-assessment as a demonstration of the reliability of the pedagogical perspective in exploring the effective use of technology in education.
