Define a graph GT (n) with one node for each triangulation of a convex n-gon. Place an edge between each pair of nodes that differ by a single flip: two triangles forming a quadrilateral are exchanged for the other pair of triangles forming the same quadrilateral. In this paper we introduce a tree of all triangulations of polygons with any number of vertices which gives a unified framework in w...

In 1870, a thirty-one-year-old professeur at a French provincial lycée published a work whose goal was no less than to foment a revolution within the tradition of French psychological investigation. La psychologie anglaise contemporaine (1870), by normalien Théodule Ribot, might seem an unlikely title for a piece of intellectual bomb throwing. Under the guise of surveying developments within En...

A method based on fuzzy set theory is presented to incorporate imprecise thermodynamic parameters into chemical equilibrium calculations of aqueous systems. Imprecision may arise from uncertainties in experimental parameter determination as well as from inconsistency of available data in the literature. Fuzzy numbers with different shapes of membership functions are used to express imprecision ...

-Theoretical and experimental studies dealing with the spray ignition phenomena are reviewed. Two major topics covered are external-source ignition of liquid fuel sprays and spontaneous spray ignition. Experimental and theoretical investigations of external-source ignition of sprays employing different configurations are discussed first. Three major topics included here are: (i) ignition of qui...

The objectives of the Consulting Assistance on Economic Reform (CAER II) project are to contribute to broad-based and sustainable economic growth and to improve the policy reform content of USAID assistance activities that aim to strengthen markets in recipient countries. Services are provided by the Harvard Institute for International Development (HIID) and its subcontractors. It is funded by ...

1550-7998=20 We determine the weak mixing angle in the MS scheme, sin
̂W , at energy scales relevant for present and future low-energy electroweak measurements. We relate the renormalization group evolution of sin
̂W to the corresponding evolution of ̂ and include higher-order terms in s and that had not been treated in previous analyses. We also update the analysis of nonperturbative, hadronic c...
