In a recent Letter, Buhot [1] proposes that entropy driven phase separation in hard-core binary mixtures is directly related to a bond-percolation transition. In particular, Buhot suggests that a phase instability occurs when the coordination number n b , defined as n b ෇ r l Z s l #r#s l ͑11R͒ g ll ͑r͒ dr , (1) is equal to zp c , where z is the coordination number of a particular crystal lattice, ...

This paper proposes a smart grid solution for the electricity needs of North and East Sri Lanka (NE-SL); the solution proposed in this paper is a collection of smaller and greener electricity generators, geographically dispersed throughout the NE-SL region. At present, electricity is not available in most of the NE-SL due to the civil war. There is practically no electricity production and dist...

We study the decision of a manufacturer (buyer), expecting new sourcing opportunities in the future, to select between a sole and a second sourcing mechanism for a non-commodity component. In a sole sourcing mechanism, the buyer commits to source from the current supplier. In a second sourcing mechanism, the buyer keeps the option open to source from a new supplier in the future. For a buyer th...

Firstly in this paper we introduce a new concept of the 2nd power of a fuzzy number. It is exponent to production (EP) method that provides an analytical and approximate solution for fully fuzzy quadratic equation (FFQE): F(X)=D, where F(X)-AX2+BX+C. To use the mentioned EP method, at first the 1-cut solution of FFQE as a real root is obtained and then unknown manipulated unsymmetrical spreads ...

We investigated whether 16-month-old infants' past experience with a person's gaze reliability influences their expectation about the person's ability to form beliefs. Infants were first administered a search task in which they observed an experimenter show excitement while looking inside a box that either contained a toy (reliable looker condition) or was empty (unreliable looker condition). T...
