We consider a Poisson equation in Rd for the elliptic operator corresponding to an ergodic diffusion process. Optimal regularity and smoothness with respect parameter are obtained under mild conditions on coefficients. The result is then applied establish general approximation fully coupled multitime scales stochastic differential equations only Hölder continuous Four different averaged as well...

Inverter-based Operational Transconductance Amplifiers (OTAs) are versatile and friendly scalable analog circuit blocks. Especially for the new CMOS technological nodes, several recent applications have been extensively using them, ranging from Analog Front End (AFE) to analog-to-digital converters (ADC). This work tracks down current advances in inverter-based OTAs design, comparing their basi...

A simple and a novel electroanalysis of hydroxyurea (HU) drug at glassy carbon and gold electrode was investigated for the first time using cyclic, linear sweep and differential pulse voltammetric techniques. The oxidation of HU was irreversible and exhibited a diffusion controlled process on both electrodes. The oxidation mechanism was proposed. The dependence of the current on pH, the concent...

We study the interaction between an MIMD (Multiplicative Increase Multiplicative Decrease) congestion control algorithm and a Drop Tail buffer. We consider the problem in the framework of deterministic hybrid models. We first show that the hybrid model of the interaction between the MIMD congestion control and bottleneck router always converges to a cyclic behavior that can be of only two diffe...
