Evolutionary Robots with on-line self-organization and behavioral fitness

We address two issues in Evolutionary Robotics, namely the genetic encoding and the performance criterion, also known as fitness function. For the first aspect, we suggest to encode mechanisms for parameter self-organization, instead of the parameters them ...

MADM - A new multicomponent aerosol dynamics model

Athanasios Nenes, Spyros Pandis

A Multicomponent Aerosol Dynamics Model (MADM) capable of solving the condensation/evaporation equation of atmospheric aerosols is presented. Condensable species may be organic and/or inorganic. For the inorganic constituents the equilibrium model ISORROPI ...

Physical activity monitoring based on accelerometry: validation and comparison with video observation

Kamiar Aminian, Philippe Robert

The objective of this feasibility study is to evaluate the use of the 'Physilog' device, an ambulatory physical- activity recorder based on acceleration measurement, for the monitoring of daily physical activities. Accelerations measured at the level of th ...

A new method for body posture detection using a kinematic sensor

Kamiar Aminian, Philippe Robert, Bijan Najafi

The objective of this study is to present a new method of physical activity monitoring, able to detect body postures (sitting, standing and lying) from only one kinematic sensor attached on the chest. Wavelet analysis in conjunction with a simple kinematic ...

Continued development and testing of a new thermodynamic aerosol module for urban and regional air quality models

Athanasios Nenes, Spyros Pandis

A computationally efficient and rigorous thermodynamic model (ISORROPIA) that predicts the physical state and composition of inorganic atmospheric aerosol is presented. The advantages of this particular model render it suitable for incorporation into urban ...

On the use of shock-capturing schemes for large-eddy simulation

Michel Deville, Pascal Comte, Michele Mossi

"Numerical simulations of freely decaying isotropic fluid turbulence were performed at various Mach numbers (from 0.2 to 1.0) using known shock-capturing Euler schemes (Jameson, TVD-MUSCL, ENO) often employed for aeronautical applications. The objective of ...

ISORROPIA: A new thermodynamic equilibrium model for multiphase multicomponent inorganic aerosols

Athanasios Nenes, Spyros Pandis

A computationally efficient and rigorous thermodynamic model that predicts the physical state and composition of inorganic atmospheric aerosol is presented. One of the main features of the model is the implementation of mutual deliquescence of multicompone ...

God Save the Red Queen! Competition in Co-Evolutionary Robotics

Dario Floreano

In the simplest scenario of two co-evolving populations in competition with each other, fitness progress is achieved at disadvantage of the other population's fitness. The everchanging fitness landscape caused by the competing species (named the "Red Queen ...

Physical basis of nonequilibrium solute transport in soil

David Andrew Barry

Nonequilibrium solute transport results from both chemical and physical mechanisms. In saturated porous media the physical causes are usually taken to be film diffusion and intra-particle diffusion. Experimental data shows that nonequilibrium is affected b ...
