Unstable Behavior of Magnesium-Containing Hydroxyapatites
Caries Research, 2009Hydroxyapatites with various magnesium contents were synthesized at 80 °C and pH 7.4 to study their physicochemical stability. The contraction of their c-axis dimensions observed in X-ray diffraction analysis, together with the result of chemical analysis, suggested that Mg2+ ions are substituted into the Ca2+ positions.

Temporal behavior of an unstable optical cavity
Optics Letters, 1999The relaxation of a geometrically unstable Fabry-Perot cavity is theoretically and experimentally investigated. It is observed that the usual sum of the exponential decays of the intensities in the different transverse modes of the cavity is replaced by a more complex behavior. In particular, light couplings into the fundamental mode of the cavity with

On the unstable behavior of cement grinding circuits
1999 European Control Conference (ECC), 1999The present work deals with new observations made on a grinding plant of CBR (Mons, Belgium), which reveal an unstable behavior of the process due to the classifier. In particular, the influence of the flow rate entering the classifier is highlighted. The dynamic simulator developed and validated in a previous study is extended to include a new model ...

Mechanical behavior of unstable emulsions
Journal of Engineering Physics, 1976Results of experimental studies of the rheologic properties of unstable macroemulsions of the water-oil type are presented. A region of non-Newtonian behavior of the test emulsions is identified.

Prediction of dynamical, nonlinear, and unstable process behavior
The Journal of Supercomputing, 2008Process scheduling techniques consider the current load situation to allocate computing resources. Those techniques make approximations such as the average of communication, processing, and memory access to improve the process scheduling, although processes may present different behaviors during their whole execution.

Introduction to Unstable Processes and Their Asymptotic Behavior
2020The purpose of this chapter is to introduce the reader to the basic concepts related to unstable processes. To convince the reader that stochastically unstable processes are an important subject for consideration, let us continue with further definitions and visualizations.

Unstable behavior of plasma in inductive discharges
IEEE Conference Record - Abstracts. 1999 IEEE International Conference on Plasma Science. 26th IEEE International Conference (Cat. No.99CH36297), 2003Summary form only given. Instabilities in a transformer coupled plasma (TCP) source have been studied. An inductive discharge has been created by a 13.56 MHz RF-driven planar inductive coil mounted on the top of an aluminum cylindrical vacuum chamber.

Unstable Behavior in Exploding Wire Array
Japanese Journal of Applied Physics, 2000Although considerable investigations have been reported on z-pinches to achieve nuclear fusion, little attention has been given from the point of view of how a wire array consisting of many parallel wires explodes. In this paper, the unstable behavior of a wire array is investigated.

Application of FIDF to the detection of unstable behaviors in compression systems
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002Issues concerning the detection of surge and rotating stall in a compression system are studied. It is observed that the plenum pressure rise and mass flow rate of a compression system exhibit abrupt change due to the appearance of surge or rotating stall, while those of it's linearized model do not.

Prediction of unstable behavior in enzymatic diffusion-reaction Processes
Proceedings of the 45th IEEE Conference on Decision and Control, 2006The prediction of the behavior of biological mechanisms represents an important challenge in the comprehension of some disorders in living organisms. In this sense a better understanding of the system behavior is mandatory. In this paper we use mathematical tools and well established concepts of nonlinear dynamics and control for modeling and ...
