The multimodel ensemble exercise performed within the HTAP project context (Fiore et al., 2009) is used here as an example of how a pre-inspection, diagnosis and selection of an ensemble, can produce more reliable results. The procedure is contrasted with the often-used practice of simply averaging model simulations, assuming different models produce independent results, and using the diversity...

To realize an analog artificial neural network hardware, the circuit element for synapse function is important because the number of synapse elements is much larger than that of neuron elements. One of the candidates for this synapse element is a ferroelectric memristor. This device functions as a voltage controllable variable resistor, which can be applied to a synapse weight. However, its con...

– Lagrangian chaos is experimentally investigated in a convective flow by means of Particle Tracking Velocimetry. The Finite Size Lyapunov Exponent analysis is applied to quantify dispersion properties at different scales. In the range of parameters of the experiment, Lagrangian motion is found to be chaotic. Moreover, the Lyapunov exponent depends on the Rayleigh number as Ra1/2. A simple dime...

The presence of stenosis at the wall artery lead to further cardiovascular diseases such as heart attack, stroke and many more. Treatment a stenosed includes insertion catheter through which affects blood flow solute dispersion. This present study focuses on effect radius height dispersion behavior. problem is modelled using Herschel-Bulkley fluid represent rheology, with boundary conditions. A...

As the water waves come to coastal area, variation in dispersion relation due spatial inhomogeneity brings about deformation of wave shape. With local bathymetry effect, propagation experiences a complicated evolution process, including reflection, shoaling and breaking, etc. Considering directional spreading effect refraction becomes indispensable when it comes two-dimensional (2D) problem ran...

As an air pollutant is transported from a source to a potential receptor the pollutant disperses into the surrounding air so that it arrives at a much lower concentration than it was on leaving the source. Strict environmental regulations worldwide resulted in an ever growing concern about the validity and reliability of air quality dispersion models. The present work is a try to evaluate the a...

In this paper the present "state\ of air quality modeling (as viewed by the authors) is presented. The focus of the paper will be on the "current\ state-of-aaairs. Due to limitation of space (and the focus of this Dagstuhl Seminar) the discussion will focus on only a few aspects of air quality modeling: i.e., chemical integration, sensitivity analisys and computational framework.

While there are extensive theoretical studies on firms’ responses to environmental regulations and enforcement, there are few empirical analyses of firms’ expenditures on pollution abatement in responding to different regulations and enforcement strategies. This paper presents an empirical analysis of pollution abatement efforts of Chinese industrial firms under a combination of pollution charg...
