Certain nonlinear partially observable stochastic optimal control problems with explicit control laws equivalent to LEQG/LQG problems
(1997)This paper is concerned with partially observed stochastic optimal control problems when nonlinearities enter the dynamics of the unobservable state and the observations as gradients of potential functions. Explicit ...

Certain results concerning filtering and control of diffusions in small white noise
(IEEE, 1997)The purpose of this talk is twofold. First, we examine in detail the binary hypothesis decision and/or estimation problem using a risksensitive cost criterion, when the state and observation processes are diffusion signals. ...

Classes of nonlinear partially observable stochastic optimal control problems with explicit optimal control laws
(1998)This paper introduces certain nonlinear partially observable stochastic optimal control problems which are equivalent to completely observable control problems with finitedimensional state space. In some cases the optimal ...

Computational assessment of distributed decomposition methods for stochastic linear programs
(1998)Incorporating uncertainty in optimization models gives rise to large, structured mathematical programs. Decomposition procedures are wellsuited for parallelization, thus providing a promising venue for solving large ...

Designing stable inverters and state observers for switched linear systems with unknown inputs
(2006)We present a method for estimating the inputs and states in discretetime switched linear systems with unknown inputs. We first investigate the problem of system invertibility, which reconstructs the unknown inputs based ...

Encoded finitestate machines for nonconcurrent error detection and identification
(2003)In this paper we develop a methodology for systematically constructing redundant finitestate machines in a way that enables an external mechanism to detect and identify transient statetransition faults by performing ...

A mechanistic approach in defining inelastic rotation capacity of RC columns
(National Technical University of Athens, 2017)When a reinforced concrete (RC) column is subjected to lateral sway as a result of earthquake action, the large strain demand in the end sections is supported by development of strains in the anchorage. This causes the ...
