The effects of thermal radiation on dry convection
… arises as monotonically growing cells, not as an oscillatory instability. That is, we prove exchange of stabilities. We investigate the linear stability modes. We find that in most cases, the linear stability threshold can be described approximately or exactly in terms of a radiative Rayleigh …

Instabilities in layered liquids induced by external fields
… this effective dilation leads to an undulation instability. To investigate the stability of the parallel alignment, we performed a linear and weakly non-linear analysis of the governing equations. The initial state is the above described spatially homogeneous director tilt with the smectic …

Inestabilidad oscilatoria y sus aplicaciones en mecánica de fluidos y combustión
… en la literatura. ABSTRACT The onset of the oscillatory instability is analyzed, in systems whose size in one spatial direction is large as compared with the characteristic wavelength of the instability . This instability is one of the generic bifurcations form steady states to more complex …

Wide Area Analysis and Application in Power System
Frequency monitoring network (FNET) is an Internet based GPS synchronized wide-area frequency monitoring network deployed at distribution level. At first part of this thesis, FNET structure and characteristics are introduced. After analysis and smoothing FDR signals, the algorithm of event trigger …
