Reliability of Large and Complex Systems:

Asymptotic Approach Research

Prof. dr hab. Krzysztof Kołowrocki

Department of Mathematics, Maritime University, Gdynia, Poland

The lecture is concerned with the application of limit reliability functions to the reliability evaluation of large systems. Two-state and multi-state large systems composed of independent components are considered. The main emphasis is on multi-state systems with ageing components because of the importance of such an approach in reliability analysis, assessment and prediction, and analyzing the effectiveness of operation processes of real technical systems.

New Computing Technology in Reliability Engineering

Prof. Radim Bris

VSB - Technical University of Ostrava, Czech Republic

Rapid development of computer technology recently requires adequate novelties of source codes and appropriate software. New computing technology based on HPC (High Performance Computing) for availability calculation will be demonstrated in this lecture. The technology is particularly effective in context with simulation methods, but analytical methods are taken into account as well. Basic algorithms for availability calculations must be improved to achieve better computational efficiency.

When smartphones are neither available nor green

Iosif I. Androulidakis, PhD.

University of Ioannina, Greece

Unlike confidentiality and privacy concerns, the preservation of availability of mobile phone service has not received the same extent of research, albeit an important factor, especially in business but also in life threatening situations. In this talk we will present a collection of practical battery deprivation denial of service attacks that render mobile phones unavailable and non-green! We will mostly be focusing on attacks against the mobile terminal and not against the network. A variety of scenarios is proposed encompassing visible and stealth SMS as well as very short calls, interrupted before the phone actually rings. These methods force the mobile phone to continuously transmit, consuming energy up to the point of complete battery depletion. Current flow and power consumption can be measured in a variety of ways, while a thermal camera can further measure the rise in temperature. It is shown that it is trivially easy to launch such a denial of service attack, with minimal cost and resources while the attack is completely stealthily without the victims being able to realize they are under attack.

Toward Classification of Data Coming from Evaluation Sheets of Subjects with ASDs

Dr inż. Krzysztof Pancerz

University of Management and Administration in Zamosc, Poland

The lecture concerns the first step of research on adaptation of computational intelligence methods, with particular regard to data mining and machine learning ones, for computer aided-decision support in diagnosis and therapy of persons with autism spectrum disorders (ASDs). Analyzed data come from evaluation sheets of subjects with ASDs in 17 spheres (among others, self-service, communication, cognitive, functioning in the social and family environment, physical, etc.). Experiments testing the relative effectiveness of different methods are performed on data describing over 70 cases (subjects) classified into three categories: high-functioning, medium-functioning, or low-functioning autism.

Prospects of Computing Platform for Real-World Intelligent Systems

Prof. Michitaka Kameyama

Graduate School of Information Sciences, Tohoku University, Japan

As real-world applications, we consider advanced intelligent systems such as a highly-safe system and an intelligent robot system which make our daily life safe and comfortable. Such a real-world intelligent system consists of three basic modules: recognition and understanding of real-world environment, prediction and estimation for unknown and future information, and planning of an action on real-world output. High-performance, low-power and low-cost implementation is important for the industrial products, so that genetic hardware/software universal platform for all the real-world intelligent systems is required to be developed. In the platform, universality originated from resource utilization is also an important factor in not only hardware but also software implementation, which results in low development cost and high-quality processing. A novel dynamic reconfigurable VLSI processor for real-time adaptation of the algorithm selection is also presented.
