Unstable detonations in the near-limit regime in tubes

Symposium (International) on Combustion, 1991
Unstable detonations in near-limit gaseous mixtures are investigated in five tubes of 152, 97, 74, 49, and 38 mm i.d. respectively and 11 m long, interconnected by 1980 o bends to form a continuous loop. The detonation is initiated in the largest tube by a solid explosive charge and transmits to the smaller tubes through the bends.

Strategic Niche Management in an unstable regime: Biomass gasification in India

Environmental Science & Policy, 2010
This paper analyses the development and implementation of biomass gasifiers in India. Based on literature reviews and fieldwork, an historical narrative is presented starting with laboratory experiments in the 1980s up to commercial applications after 2000. This narrative is analysed using the Strategic Niche Management framework.

Quasi-periodic regimes in the transition to unstable Lagrange dynamics

Technical Physics Letters, 2006
The appearance of a narrow band of quasi-periodic regimes between the regions of periodic (stable) and unstable (in the Lagrange sense) dynamics in the space of parameters of a dynamical system has been studied in the case of a model two-dimensional Henon map.

Initial and regime situations in the decay of unstable quantum systems

Il Nuovo Cimento A, 1980
Two different definitions of survival probability in the decay of an unstable quantum system are considered and the equations for them are deduced from the equation for the density operator. The regime situation for the ensemble of unstable systems is studied and the density operator in such a situation is derived.

Spinodal patterns indicating unstable regime of polymer crystallization

Journal of Polymer Science Part B: Polymer Physics, 2004
AbstractIt has been considered that crystallization of polymer from melt proceeds via the coexistence of molten matrix and growing crystals that have once overcome a nucleation barrier to a critical size. The nucleation process has often been explained analogously with so‐called nucleation and growth (NG) behavior of the phase separation of a binary ...

Ignition and unstable regimes of gasless combustion of a disk-shaped sample

Combustion, Explosion, and Shock Waves, 2017
The effect of ignition conditions and the parameters of the melting of the inert component on unstable combustion modes is studied numerically using a model of solid-flame combustion of a disk. It is shown that the shape of the heated region initiating combustion of the disk determines the number and trajectories of hotspots of the self-propagating ...

Stable and Unstable Regimes of Plasma Diodes in the Presence of Electron Collisions

Technical Physics, 2019
A thermionic energy converter as the Pierce diode of which the interelectrode space is filled with a uniform background of immobile ions is considered. The features of stability of its time-independent solutions are investigated under electron collisions with background gas. The solutions are obtained analytically by the Lagrange method.

Earth Tide Analysis Specifics in Case of Unstable Aquifer Regime

Pure and Applied Geophysics, 2017
We consider the main factors that affect underground water flow including aquifer supply, collector state, and distant earthquakes seismic waves’ passage. In geodynamically stable conditions underground inflow change can significantly distort hydrogeological response to Earth tides, which leads to the incorrect estimation of phase shift between tidal ...

The BW 2 regime: an unstable disequilibrium bound to unravel

International Economics and Economic Policy, 2006
The paper presents a critical analysis of the Bretton Woods 2 (BW2) hypothesis. According to this view China, other Asian economies and other emerging market economies follow mercantilist policies of maintaining fixed pegs to the US dollar at undervalued levels as a way to pursue export-led growth.
