FOUNDATIONS OF FRACTIONAL DYNAMICS

Fractals, 1995
Time flow in dynamical systems is reconsidered in the ultralong time limit. The ultralong time limit is a limit in which a discretized time flow is iterated infinitely often and the discretization time step is infinite. The new limit is used to study induced flows in ergodic theory, in particular for subsets of measure zero.

The dynamics of contract plasma fractionation

Biologicals, 2017
Plasma Derived Medicinal Products (PMDPs) are an essential component of the modern therapeutic armamentarium. They are differentiated from most other medicines in several ways, particularly the unique nature of the raw material used for their manufacture.

Continued fractions as dynamical systems

Applied Mathematics and Computation, 2012
In the paper under review, the authors study a dynamical systems approach to continued fractions. It is well-known that there is an interpretation of the continued fraction expansion process as a discrete two-dimensional dynamical system. On the contrary, in the present paper the authors study a new three-dimensional dynamical system which can be used ...

Void fraction dynamics in fluidization

AIP Conference Proceedings, 1992
A nonlinear evolution equation for void fraction in fluidization is derived from a one‐dimensional continuous model by applying the method of adiabatic eliminations. Based on our equation, the dynamics near the transitions point from stable fluidized beds to unstable ones is investigated. Phase separations in fluidized beds are also discussed.

Fractional Dynamics in Mechanical Manipulation

Journal of Computational and Nonlinear Dynamics, 2007
This paper analyzes the signals captured during the movement of a mechanical manipulator carrying a liquid container. In order to study the signals, an experimental setup is implemented. The system acquires data from the sensors, in real time, and, in a second phase, processes them through an analysis package.

Fractional Brownian dynamics in proteins

The Journal of Chemical Physics, 2004
Correlation functions describing relaxation processes in proteins and other complex molecular systems are known to exhibit a nonexponential decay. The simulation study presented here shows that fractional Brownian dynamics is a good model for the internal dynamics of a lysozyme molecule in solution.

DYNAMICS OF FRACTIONATORS WITH STRUCTURED PACKING

Chemical Engineering Communications, 1993
A generalized dynamic model of a distributed staged (packed) fractionator is developed in this work. In particular we consider the dynamics of fractionators which employ structured packings as a means of achieving mass and heat transfer in multi-component systems.

Fractional Dynamics: A Statistical Perspective

Volume 5: 6th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2007
Fractional calculus is a mathematical paradigm that has been increasingly adopted to describe the dynamics of systems with hereditary characteristics, or that reflect an average of a large population of micro elements. In this line of thought, this article analyzed the statistical dynamics of a system composed of a large number of micro-mechanical ...
