Une mŽthode mettant en Ïuvre des moyennes conditionnelles est appliquŽe aux modŽlisations de la combustion et de la formation des polluants dans les moteurs ˆ allumage commandŽ avec charge stratifiŽe. Un systme d'Žquations dŽcrit, pendant la combustion, la composition et la tempŽrature locales du gaz encore non bržlŽ. Le modle de flamme cohŽrente (CFM) a ŽtŽ choisi pour simuler la combustion ...

usually sufficient number of data of the hydrological variables is not available for frequency analysis. therefore, through the method of regional analysis the sample data are used for fitting with probability distributions and for probability theories regarding statistical population. the results of regional analysis would be valid, in case of the study region to be homogeneous in the view of ...

In this paper, the issue of whether willingness to pay (WTP) for the benefits generated by a public good should be elicited on an individual or a household basis is addressed. Differences between individual and household WTP may arise when members of the household are mutually altruistic. It is shown that, for general specifications of altruism, household WTP is less than the sum of household m...

A unitary quantum gas is a gas of quantum particles with a binary interaction of infinite scattering length and negligible range. It has been produced in recent experiments with gases of fermionic atoms by means of a Feshbach resonance. Using the Fermi pseudo-potential model for the atomic interaction, we show that the time evolution of such a gas in an isotropic three-dimensional time dependen...

Companies today have to adopt strategies that embrace both a closer reaction to the customers’ needs and efficiency. Mass customisation meets this challenge by offering individually customised goods and services with mass production efficiency. According to a number of recent surveys, there is evidence for the increasing importance of this strategy in various industries. But what do the custome...
