Knowing the conserved quantities that a galaxy's stellar orbits conform to is important in helping us understand distribution and structures within galaxy. Isolating integrals of motion resonances are particularly important, non-isolating less so. We compare behavior results two methods for counting number quantities, one based on correlation integral approach other more recent method using mac...

The focus of this research is on dynamical modeling in scientific reasoning. Dynamical modeling uses, transforms, and constructs models which capture the causal and structural dynamics of given phenomena. I describe a computational theory of dynamical modeling which utilizes representational and processing languages from artificial intelligence to represent and manipulate the dynamical models u...

In this paper, a dynamical model-based SMC (Sliding Mode Control) is proposed fortrajectory tracking of a 3-RPS (Revolute, Prismatic, Spherical) parallel manipulator. With ignoring smallinertial effects of all legs and joints compared with those of the end-effector of 3-RPS, the dynamical model ofthe manipulator is developed based on Lagrange method. By removing the unknown Lagrange multipliers...

In this paper, we propose a new dynamical fuzzy modeling technique for SISO complex systems. It is seen that, the whole state-space of a complex system is divided into subspaces and a linear time-invariant (LTI) model is then used tu approximate the complex system in each subspace. However, the global dynamical fuzzy model of the complex system is derived by aggregating all subsystem poles and ...

We investigate the relation between two quantitative measures characterizing short term memory in input driven dynamical systems, namely the short term memory capacity (MC) [3] and the Fisher memory curve (FMC) [2]. We show that even though MC and FMC map the memory structure of the system under investigation from two quite different perspectives, for linear input driven dynamical systems they ...

1 General introduction Semantic modeling of information, knowledge and language mostly assumes a static definition of the world. Concepts and instances of these concepts are defined as a static model; language and expressions are related to this specification. Even dynamic systems consider the most recent version of some reality as the preferred definition and only require updating the model to...
