An Equivalent Time Approach for Scaling the Mechanical Alloying Processes
(Elsevier, 2008)
Dynamics of a single ball into a planetary ball mill is analyzed leading to a cubic dependence of the power transferred during milling with the rotational speed, Ω. This leads to the definition of an equivalent time to ...

A Membrane Computing View on Tumours
(2006)
In this paper we discuss about the potential usefulness of P systems as natural tools for modelling tumours. This is done both from a macroscopic point of view, by considering the tumour as a growing mass of cells, as ...

Convergence and error estimates of two iterative methods for the strong solution of the incompressible korteweg model
(World Scientific, 2009-09)
We show the existence of strong solutions for a fluid model with Korteweg tensor, which is obtained as limit of two iterative linear schemes. The different unknowns are sequentially decoupled in the first scheme and in ...

Structural changes during the natural aging process of InN quantum dots
(American Institute of Physics, 2009-01)
The natural aging process of InN nanostructures by the formation of indium oxides is examined by transmission electron microscopy related techniques. Uncapped and GaN-capped InN quantum dots (QDs) on GaN/sapphire substrates ...

Compact Calibration Circuit for Large Neuromorphic Arrays
(IEEE Computer Society, 2008)
Low current applications, like neuromorphic circuits, where operating currents can be as low as few nano amps or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precision. Here we ...

Permanence and asymptotically stable complete trajectories for nonautonomous Lotka-Volterra models with diffusion
(Society for Industrial and Applied Mathematics, 2009)
Lotka-Volterra systems are the canonical ecological models used to analyze population dynamics of competition, symbiosis or prey-predator behaviour involving different interacting species in a fixed habitat. Much of the ...

Design of a FFT/IFFT module as an IP core suitable for embedded systems
(IEEE Computer Society, 2007)
In this work, we have laid the foundations that allow us to accomplish the implementation of a FFT/IFFT module as an IP core. The main objective is to design a configurable optimized core that can be integrated as a ...

Hierarchical clustering with Membrane Computing.
(Institute of Informatics Slovak Academy of Sciences, 2008)
In this paper we approach the problem of hierarchical clustering through membrane computing. A specific P system with external output is designed for each Boolean matrix associated with a finite set of individuals. The ...
