On electron-positron pair production using a two level on resonant multiphoton approximation
I. Tsohantjis, S. Moustaizis, I. Ploumistakis
We present an indepth investigation of certain aspects of the two level on resonant multiphoton approximation to pair production from vacuum in the presence of strong electromagnet…
Histograms and Wavelets on Probabilistic Data
Graham Cormode, Minos Garofalakis
There is a growing realization that uncertain information is a first-class citizen in modern database management. As such, we need techniques to correctly and efficiently process u…
Rollout Sampling Approximate Policy Iteration
Christos Dimitrakakis, Michail G. Lagoudakis
Several researchers have recently investigated the connection between reinforcement learning and classification. We are motivated by proposals of approximate policy iteration schem…
The semiflow of a reaction diffusion equation with a singular potential
Nikos I. Karachalios, Nikos B. Zographopoulos
We study the semiflow defined by a semilinear parabolic equation with a singular square potential . It is known that the Hardy-Poincaré inequal…
From Continuous-Time Design to Sampled-Data Design of Nonlinear Observers
Iasson Karafyllis, Costas Kravaris
In this work, a sampled-data nonlinear observer is designed using a continuous-time design coupled with an inter-sample output predictor. The proposed sampled-data observer is a hy…
Necessary and Sufficient Lyapunov-Like Conditions for Robust Nonlinear Stabilization
Iasson Karafyllis, Zhong-Ping Jiang
In this work, we propose a methodology for the expression of necessary and sufficient Lyapunov-like conditions for the existence of stabilizing feedback laws. The methodology is an…
