The dynamic behavior of programs
Proceedings of the December 9-11, 1968, fall joint computer conference, part II on - AFIPS '68 (Fall, part II), 1968A computer system consists of several resources for which users' programs are competing: CPU time, primary and secondary storage and Input-Output devices. More and more computer systems, which are being marketed currently, allow for resource sharing among several jobs, in order to obtain a better utilization of all available equipment, or to provide ...

Behavioral variability in an evolutionary theory of behavior dynamics
Journal of the Experimental Analysis of Behavior, 2016McDowell’s evolutionary theory of behavior dynamics (McDowell, 2004) instantiates populations of behaviors (abstractly represented by integers) that evolve under the selection pressure of the environment in the form of positive reinforcement. Each generation gives rise to the next via low‐level Darwinian processes of selection, recombination, and ...

Dynamical behavior of object systems
1995A semantic framework for modeling the dynamics of object systems is proposed, based on algebraic methods and formulated categorically. The static properties of objects are described by algebraic specifications which could be given as the public interfaces of class specifications.

Dynamic Behavior of Lung Surfactant
Journal of Biomechanical Engineering, 2000We have previously developed an adsorption-limited model to describe the exchange of lung surfactant and its fractions to and from an air–liquid interface in oscillatory surfactometers. Here we extend this model to allow for diffusion in the liquid phase.

Dynamic Behavior of a Ferroelectric Actuator
Mathematics and Mechanics of Solids, 1999The authors study the effect of polarization switching on the dynamic behavior of a model ferroelectric actuator using the system dynamics approach. The analysis indicates that the stress resulting from polarization switching always oscillates at a frequency slightly lower than the system resonance frequency if the applied electric field is harmonic ...

Dynamical behavior of boron clusters
Nanoscale, 2016Several of the lowest energy structures of small and medium sized boron clusters are two-dimensional systems made up of a pair of concentric rings. In some cases, the barriers to the rotation of one of those rings relative to the other are remarkably low.

On the dynamic behavior of a hydraulic cylinder
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002We are interested in the stability properties of a hydraulic cylinder when no control is applied.

Study of the dynamic behavior of RALPHY
Proceedings of 1993 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS '93), 2002The authors propose a control/command scheme for the quadruped robot RALPHY (French acronym for legged robot with pneumatic actuators) which takes into account both dynamical and real time aspects as well as theoretical and practical approaches. They decompose the dynamic model for the whole robot into two parts in order to distribute hierarchically ...

Chaotic Behavior and Fluid Dynamics
1981It is shown that while fluids are very complicated systems having many degrees of freedom, the basic mechanism underlying the observed chaotic behavior of fluid turbulence may not require the consideration of many degrees of freedom. Simple dynamical systems display erratic and chaotic behavior reminiscent of turbulence, the key to which is the ...

Dynamics of Self-Injurious Behaviors
American Journal on Mental Retardation, 1999Self-injurious behavior was examined in a case study of head-banging by an 8-year-old girl with profound mental retardation and an autistic disorder. Trajectories of the arm movements and impact forces of the head blows were determined from a dynamic analysis of videotapes. Results revealed a high degree of cycle-to-cycle consistency in the qualitative
