Average Fisher information maximisation in presence of costconstrained measurements
(The Institution of Engineering and Technology, 2011)An optimal estimation framework is considered in the presence of costconstrained measurements. The aim is to maximise the average Fisher information under a constraint on the total cost of measurement devices. An optimisation ... 
Average fisher information optimization for quantized measurements using additive independent noise
(IEEE, 2010)Adding noise to nonlinear systems can enhance their performance. Additive noise benefits are observed also in parameter estimation problems based on quantized observations. In this study, the purpose is to find the optimal ... 
Convexity properties of outage probability under Rayleigh fading

Detector randomization and stochastic signaling for minimum probability of error receivers
(Institute of Electrical and Electronics Engineers, 2012)Optimal receiver design is studied for a communications system in which both detector randomization and stochastic signaling can be performed. First, it is proven that stochastic signaling without detector randomization ... 
Dwell time optimization in switching control of parameter varying time delay systems
(IEEE, 2011)It has been shown that parameter varying systems with time delays can be robustly stabilized by switching control, provided that the plant's parameter varies slowly enough such that the dwell time conditions of the switched ...

Optimal stopping problems for asset management
(2012)An asset manager invests the savings of some investors in a portfolio of defaultable bonds. The manager pays the investors coupons at a constant rate and receives a management fee proportional to the value of the portfolio. ...

Wiener disorder problem with observations at fixed discrete time epochs
(Institute for Operations Research and the Management Sciences (I N F O R M S), 2010)Suppose that a Wiener process gains a known drift rate at some unobservable disorder time with some zeromodified exponential distribution. The process is observed only at known fixed discrete time epochs, which may not ...
