Robust Chaos Generation on the Basis of Symmetry Violations in Attractors

We present a method for generating robust chaos. It is based on the search algorithm weak symmetry violation in the reconstructed attractor. On its basis the smooth functions in the form of a system of finite-difference equations. To ensure robust chaos generator introduced piecewise continuous member. The simulation results are given in the report.Comment: 3 pages, 2014 2nd International Conference on Emission Electronics (ICEE), Saint-Petersburg, Russi

Laboratory Test Bench for Research Network and Cloud Computing

At present moment, there is a great interest in development of information systems operating in cloud infrastructures. Generally, many of tasks remain unresolved such as tasks of optimization of large databases in a hybrid cloud infrastructure, quality of service (QoS) at different levels of cloud services, dynamic control of distribution of cloud resources in application systems and many others. Research and development of new solutions can be limited in case of using emulators or international commercial cloud services, due to the closed architecture and limited opportunities for experimentation. Article provides answers to questions on the establishment of a pilot cloud practically "at home" with the ability to adjust the width of the emulation channel and delays in data transmission. It also describes architecture and configuration of the experimental setup. The proposed modular structure can be expanded by available computing power.Comment: 5 page

THE CHOICE OF TECHNOLOGICAL SOLUTIONS FOR SOFTWARE DEVELOPMENT FOR DISTRIBUTED INFORMATION SYSTEMS

The choice of tools and programming technologies for creating information systems is a current trend. Each projected system needs you to define a set of criteria for the development environment used by li- braries and technologies. This article considers a choice of technological solutions using an example of the developed digital computing web platform of the Russian Academy of Education to provide information support to the activities of psychologists doing research, including population and longitudinal studies. The peculiarity of the system are: magnitude and significant development time requiring the implementa- tion and assurance of the guaranteed computing reliability of a wide range of digital tools used in psycho- logical research; maintenance of functioning in various conditions, in particular when carrying out mass research in schools with different characteristics of computing resources and communication channels; the possibility of scaling services; security and data privacy, as well as the use of technologies and pro- gramming tools that would ensure the compatibility and conversion of data with other means of process- ing psychological research. For the developed system, criteria were introduced for evaluating software technologies that take into account the features of the functioning and life cycle of a product, a specific example shows the selection of appropriate technological solutions. An important component in the de- velopment is the training of the development team for the technologies used. A system that implements the training program for selected technologies is given. The developed training system is used to reduce the time of inclusion in the development of new software developers, as the tasks are expanded

Stabilization system of a bipedal non-anthropomorphic robot AnyWalker

International audienceWe present a bipedal walking non-anthropomorphic robot AnyWalker developed in the laboratory of robotics and mechatronics of the Kuban State University. The goal is to be able to overcome obstacles exceeding the size of the robot itself. In addition to the degrees of freedom due to the joints between the links, the robot is equipped with reaction wheels enhancing its dynamic stabilization capabilities. This paper presents a study of the stability zones in the frontal plane of the robot with and without the reaction wheel support
