Sobolev V.E. - Computer Simulation of Physical Processes with Multi-dimensional Time pp. 35-43


Abstract: The artice is devoted to discussing whether it is possible to create a computer simuation of physical processes ongoing within the framework of hypothetic universes where the dimension of time exceeds one unit. This problem is viewed in terms of digital physics assuming that our Universe can be a virtual sumulation operated by a computer program based on initial conditions and a set of algorithms that determine the rules of the Universe evolution. In his research Sobolev analyzes the main evolutionary principles of classical and quantum systems as well as evolutionary principles of hypothetic systems with multidimensional time. The author carries out a comparative analysis of one-dimensional and multi-dimensional time systems and considers the main distinctive features of system evolution within the framework of the multidimensional time of events. The author also views examples of systems with a finite and infinite number of timporal dimensions. The author shows that algorithmization of processes ongoing in multi-dimensional time systems requires logics fundamentally different from logics of the evolution of our physical reality with the time dimension being equal to one unit.  
Afon'shin V.E., Rozhentsov V.V. - Technology for measuring the critical flicker frequency pp. 60-67


Abstract: The critical flicker frequency is the frequency at which a flickering light source is subjectively perceived by a person as luminous. It is shown that the critical flicker frequency method is used for diagnostic purposes when solving various scientific and applied problems. The subject of research is the conditions for using the method of critical flicker frequency. Their limitations are due to the need: a distraction from the work to be performed to measure the critical flicker frequency, to perform measurements in stationary conditions. The aim of the work is to expand the functional capabilities of the critical flicker frequency method by using augmented reality technology. To measure critical flicker frequency, light flashes with varying frequency are formed by a mobile device in the form of augmented reality. The novelty of the proposed technology is: 1) to increase the reliability of diagnostics by the method of critical flicker frequency due to its measurement in the course of the work performed; 2) carrying out diagnostics not only in stationary ground conditions, but also during ground, water or flight movements of the subject, which was previously difficult or impossible.
