Atmospheric water vapor emits strongly at millimeter wavelengths. Fast temporal and spatial fluctuations in the atmospheric water vapor results in problems in removing the atmospheric emission, which is done by very quick position switching or beam switching. Most phase fluctuations seen with the 11.2 GHz site testing interferometer are due to fluctuations in water vapor, so we can use the stat...

We investigate the instabilities of a linear damped oscillator due to fluctuations of the damping parameter. The fluctuations are driven either by Gaussian white noise or Poisson white noise (white shot noise). We consider three notions of stability. The first two are the well-known notions of stability in the mean and stability in the mean square. We introduce the concept of thermodynamic stab...

This dissertation consists of three essays organized as chapters. On the first chapter, I revisit the discussions which evaluate different fluctuations of major economic variables produced by different monetary policy rules for small open economies, given the existence of liability dollarization. In particular, monetary rules which either include or exclude exchange rate stability as a monetary...

The stability of a plasma/semiconductor for small fluctuations in the intensity of plane electromagnetic beam has been studied when a non-linearity in the dielectric constant appears on account of the diffusion of non-uniformly heated carriers (due to fluctuations in the intensity of the beam). Fluctuations of optimum size and long duration have been found to grow at moderate powers. The effect...
