Three-dimensional modelling of the tidal dispersion of non-conservative radionuclides in the marine environment. Application to 239,240 Pu dispersion in the eastern Irish Sea
(Elsevier, 1999)
A three-dimensional model to simulate the tidal dispersion of non-conservative radionuclides in a marine environment has been developed. The model solves the three-dimensional hydrodynamic equations using normalized s ...

Reliable analysis of settling errors in SC integrators - application to high-speed low-power ΣΔ modulators design
(1999)
This paper presents a detailed study on the transient response of SC integrators taking into account the effects of amplifier finite gain-bandwidth product and slew-rate during, unlike previous models, both the integration ...

Design issues for the VLSI implementation of universal approximator fuzzy systems
(Institute of Electrical and Electronics Engineers, 1999)
Several VLSI realizations of fuzzy systems have been proposed in the literature in the recent years. They employ analog or digital circuitry, offering more or less programmability, implementing difference inference methods, ...

Harmonic Distortion in Fully-Differential Switched-Current Sigma-Delta Modulators
(1999)
This paper presents a systematic analysis of the harmonic distortion in SD modulators (SDMs) implemented with fully-differential switched-current (SI) circuits. Closed form expressions are derived for the third-order ...

A modular programmable CMOS analog fuzzy controller chip
(Institute of Electrical and Electronics Engineers, 1999)
We present a highly modular fuzzy inference analog CMOS chip architecture with on-chip digital progranirnability. This chip consists of the interconnection of parameterized instances of two different kind of blocks, namely ...

A generalization of path following for mobile robots
(IEEE Computer Society, 1999)
Several authors have proposed some methods for applying path following in specific cases to mobile robots. When we try to extend the path following approach to the general problem several difficulties arise. We present a ...
