Directly computable L2 and L∞ performance bounds for morse's dynamic certainty equivalence adaptive controller
(1995)In this paper we consider a model reference adaptive control scheme where the classical error augmentation and standard tuning error normalization are avoided through the use of Morse's high‐order tuner. We consider the ...

Enhanced group analysis and exact solutions of variable coefficient semilinear diffusion equations with a power source
(2009)A new approach to group classification problems and more general investigations on transformational properties of classes of differential equations is proposed. It is based on mappings between classes of differential ...

Enhanced group classification of Gardner equations with time-dependent coefficients
(2015)We classify the Lie symmetries of variable coefficient Gardner equations (called also the combined KdV-mKdV equations). In contrast to the particular results presented in Molati and Ramollo (2012) we perform the exhaustive ...

Group analysis of Benjamin - Bona - Mahony equations with time dependent coefficients
(2015)Group classification of a class of Benjamin-Bona-Mahony (BBM) equations with time dependent coefficients is carried out. Two equivalent lists of equations possessing Lie symmetry extensions are presented: up to point ...

Minimizing expectation plus variance
(2012)We consider strategic games in which each player seeks a mixed strategy to minimize her cost evaluated by a concave valuation V (mapping probability distributions to reals)

A new linear adaptive controller: Design, analysis and performance
(2000)The certainty equivalence and polynomial approach, widely used for designing adaptive controllers, leads to "simple" adaptive control designs that guarantee stability, asymptotic error convergence, and robustness, but not ...

A new robust adaptive control scheme for linear time varying plants
(2002)In a recent work, a new linear adaptive controller based on certainty-equivalence and backstepping design, which promises a level of transient and asymptotic performance comparable to that of the tuning functions adaptive ...

Numerical investigation of the nonlinear heat diffusion equation with high nonlinearity on the boundary
(2008)A nonlinear heat diffusion problem is considered when the thermal conductivity and heat capacity are nonlinear functions of the temperature. At one of the boundaries a highly nonlinear condition is imposed involving both ...

On the invariants of two dimensional linear parabolic equations
(2012)We consider the most general two dimensional linear parabolic equations. Motivated by the recent work of Ibragimov et al. [1-3] we construct differential invariants, semi-invariants and invariant equations. These results ...

Strength of counting networks
(1996)This paper shows that any counting network, made up of balancers whose fan-in and fan-out vary arbitrarily, is, indeed, strong enough to simultaneously support both Fetch&Increment and Fetch&Decrement operations, once each ...
