Distributed systems with symmetries: general properties arising from an application
نویسنده
چکیده
The discussion in this talk follows from a recent contract to study control strategies for the segmented primary mirror of the European Extremely Large Telescope (E-ELT), in a comprehensive realistic setting. The talk starts by describing this application and naturally relates it to a distributed systems approach. Then it describes several specific issues and solutions for the control of the E-ELT; among others, global and local control approaches are compared. Relevant symmetries are mentioned along the way. Finally, some general ideas for the study of distributed systems with symmetries are derived from observations on the application. They include a link with partial differential equations and fundamental robustness issues. The combination of interaction graphs, control decisions based on local information estimates, and general system properties could lead to discussions involving diversified interests of the research unit.

On properties of dependent general progressively type-II censored order statistics
In the literature of life-testing, general progressive censoring has been studied extensively. But, all the results have been developed under the key assumption that the units undertest are independently distributed. In this paper, we study general progressively Type-II censored order statistics arising from identical units under test which are jointly distributed according to an Archimedean co...
متن کاملReduction of Differential Equations by Lie Algebra of Symmetries
The paper is devoted to an application of Lie group theory to differential equations. The basic infinitesimal method for calculating symmetry group is presented, and used to determine general symmetry group of some differential equations. We include a number of important applications including integration of ordinary differential equations and finding some solutions of partial differential equa...
متن کاملPartial Observation in Distributed Supervisory Control of Discrete-Event Systems
Distributed supervisory control is a method to synthesize local controllers in discrete-eventsystems with a systematic observation of the plant. Some works were reported on extending this methodby which local controllers are constructed so that observation properties are preserved from monolithic todistributed supervisory control, in an up-down approach. In this paper, we find circumstances in ...
متن کاملA Diffusion Equation with Exponential Nonlinearity Recant Developments
The purpose of this paper is to analyze in detail a special nonlinear partial differential equation (nPDE) of the second order which is important in physical, chemical and technical applications. The present nPDE describes nonlinear diffusion and is of interest in several parts of physics, chemistry and engineering problems alike. Since nature is not linear intrinsically the nonlinear case is t...
متن کاملNonlinear Diffusion-Convection Systems: Lie and Q-Conditional Symmetries
arising in several application [4]. Lie symmetry of BEq was found in [5], while the Q-conditional symmetry (i.e., non-classical symmetry [6]) was described in [7] and [8]. In the general case a wide list of Lie symmetries for DC equations of the form (1) is presented in [9]. A complete description of Lie symmetries, i.e., group classification of (1) has been done in [10]. The Q-conditional symm...
