Optimization of fully observable nonlinear stochastic uncertain controlled diffusion: Monotonicity properties and optimal sensitivity
(2004)
This paper is concerned with fully observable nonlinear stochastically controlled diffusions, in which uncertainty is described by a relative entropy constraint between the nominal measure and the uncertain measure, while ...
Stochastic optimal control subject to variational norm uncertainty: Viscosity subsolution for generalized HJB inequality
(2009)
This paper is concerned with optimization of stochastic uncertain systems, when systems are described by measures and the pay-off by a linear functional on the space of measure, on general abstract spaces. Robustness is ...
Distributed stochastic power control for time-varying long-term and short-term fading wireless networks
(2007)
In this paper, new time-varying wireless channel models that capture both the space and time variations of longterm and short-term fading wireless networks are developed. The proposed models are based on stochastic ...
A general framework for continuous time power control in time varying long term fading wireless networks
(2007)
In this paper, a general framework for continuous time power control algorithm under time varying long term fading wireless channels is developed. This contrasts most of the power control algorithms introduced in the ...
Stochastic power control for time-varying lognormal fading wireless channels
(2005)
The performance of stochastic optimal power control of time varying lognormal fading channels, in which the evolution of the dynamical channel is described by stochastic differential equations (SDE's), is determined. Unlike ...
Stochastic power control for time-varying fading wireless communication networks
(2005)
The performance of stochastic optimal power control for time-varying fading channels, in which the evolution of the dynamical channel is described by stochastic differential equations, is determined. Both long-term and ...
Estimation and identification of time-varying long-term fading wireless channels with application to power control
(Institute of Electrical and Electronics Engineers Inc., 2007)
This paper is concerned with modeling of time-varying wireless fading channels, parameter estimation, identification, and optimal power control from received signal measurements. Wireless channels are represented by ...
An edgeworth series expansion for multipath fading channel densities
(2002)
Identifying the statistical characteristics of the received signal in wireless communications, plays an important role in the design of different functions of the overall communications system. We demonstrate here that the ...

Thixotropy of semisolid metals
(Materials Research Society, 2000)
Understanding the time-dependent flow behavior of metal alloys in semisolid state is essential for the further development of the process. In the present investigation, the thixotropic behavior of semisolid slurries is ...
