International Centre for Theoretical Physics Optimized Random Phase Approximation for Arbitrary Reference Systems: Extremum Conditions and Thermodynamic Consistence
The optimized random phase approximation (ORPA) for classical liquids is re-examined in the framework of the generating functional approach to the integral equations. We show that the two main variants of the approximation correspond to the addition of the same correction to two di erent rst order approximations of the homogeneous liquid free energy. Furthermore, we show that it is possible to ...
متن کاملExtremum Seeking for Model Reference Adaptive Control
Adaptive control with predictable parameter convergence has remained a challenge for several decades. In the special case of set point adaptation, extremum seeking permits predictable parameter convergence by design. This is because persistency of excitation requirements are met by the sinusoidal perturbation that is part of the basic control design. Here we present results of extremum seeking ...
متن کاملInvariant Tting of Arbitrary Single-extremum Surfaces
Besl and Jain's variable order surface tting algorithm 1] is a useful method of constructing a noise-free reconstruction of 2 1 2 D range images with a small number of primitive regions. The use of bivariate polynomi-als as the approximation basis functions is linear, fast and easy to render robust. Seeding ts from regions classiied by diierential geometry is an important step towards a viewpoi...
متن کاملPhase-Type Approximations for Non-Markovian Systems
We introduce a novel stochastic process algebra, called PHASE, which directly supports phase-type distributions, useful for approximating the dynamics of non-Markovian HCI systems. In order to encourage the effective use of PHASE, we give a step by step account of how PHASE processes can be implemented in PRISM, one of the most powerful and popular probabilistic model checkers currently availab...
