ANALYSIS OF UNSTABLE BEHAVIOR OF PNEUMATIC CONVEYING SYSTEMS
Particulate Science and Technology, 1999ABSTRACT The unstable conveying zone has been recognized by many authors in their attempts to define the minimum conveying velocitv on the dilute phase side of this zone. It was found that the gas flow rate influences the magnitude and frequency of the pressure fluctuations experienced during this type of flow.

Unstable behavior of the dynamic fracture toughness
Technical Physics, 2006It is shown that the dynamic fracture toughness of materials substantially depends on the history of loading; this determines instability in the behaviour of this quantity under shock-wave loading. It is found that the minimal value of the dynamic fracture toughness can amount to 50% of the corresponding static value.

The longtime behavior of a pulse in an unstable plasma
Plasma Physics, 1970A method of asymptotic expansion is applied to the Vlasov-Maxwell set of equations to determine the characteristics of a pulse propagating in an unstable plasma. The results obtained are identical to those obtained by previous authors using transform methods coupled with the method of steepest descent.

Foreign Trade Behavior in Thailand: Stable or Unstable?
The American Economist, 2000This paper analyzes the demand for import and export functions of Thailand. It provides new evidence on both cointegration and the stability of the long-run relationship between trade flows and their determinants. Cointegration analyses are based on the Johansen (1992, 1995) system approach and the FM-OLS by Phillips and Hansen (1990) technique ...

Behavior of unstable atoms in applied fields
Physical Review A, 1979The leading radiative corrections to the behavior of atoms in time-dependent electromagnetic fields are considered. The results are expressed in closed form for the resonant measurement of the Lamb shift and fine structure of the n=2 levels of hydrogen.

Development of a Method for Controlling Unstable Vehicle Behavior
SAE Technical Paper Series, 2007<div class="htmlview paragraph">It is important to estimate the vehicle state accurately in order to control vehicle behavior. In this study, we used the vehicle sideslip angle as a value indicating vehicle instability. A new method was developed that can estimate the sideslip angle accurately without being affected by driving conditions.

Probabilistic Control and Design of Behavior in Unstable Dynamics
IFAC Proceedings Volumes, 1998Abstract We present a method of control and design of unstable dynamics based on a probabilistic coupling of distinct dynamical laws of evolution. We apply the method to the chaotic logistic map and to a model of interacting agents. As a result stabilization and control of the unstable orbits of the logistic map and the design of robust collective ...

Unstable behavior of parallel fuses as an opening switch
Digest of Technical Papers. Tenth IEEE International Pulsed Power Conference, 2002When fuses are used as a pulsed power opening switch, several are often connected in parallel to treat large energies. The waveforms of total current flowing through parallel fuses and of the output voltage could not be distinguished from those in the case of a single fuse, and therefore the currents flowing through each fuse have not been observed in ...

Behavior of Elastic-Plastic Trusses with Unstable Bars
Journal of the Engineering Mechanics Division, 1966Sufficient conditions for uniqueness of incremental response and overall stability are established and discussed for elastic plastic trusses containing unstable members. These criteria consist of the positive definiteness of matrices built up with the elastic influence coefficients of bar-forces for dislocations and with the plastic compliances of the ...

Transforming consumer behavior in an unstable environment
Actual problems of innovative economy and lawThe article presents the results of a study on the transformation of consumer behavior under conditions of economic, social, and informational instability, when traditional rational models of decision-making lose their explanatory power. It is shown that environmental turbulence changes how consumers respond to market stimuli, strengthens the influence
