The Fermat-Weber location problem is to find a point in R that minimizes the sum of the weighted Euclidean distances from m given points in R. In this paper we consider the Fermat-Weber problem of one new facilitiy with respect to n unknown customers in order to minimizing the sum of transportation costs between this facility and the customers. We assumed that each customer is located in a none...

We study three kinetic models with constraint, namely the Symmetrically Constrained Ising Chain, the Asymmetrically Constrained Ising Chain, and the Backgammon Model. All these models show glassy behavior and coarsening. We apply to them the Stillinger and Weber decomposition, and find that they share the same configurational entropy, despite of their different nonequilibrium dynamics. We concl...

We show that for any convex object Q in the plane, the average distance from the Fermat-Weber center of Q to the points in Q is at least ∆(P )/7, where ∆(P ) is the diameter of P , and that there exists a convex object for which this distance is ∆(P )/6. We use this result to obtain a linear-time approximation scheme for finding an approximate Fermat-Weber center of a convex polygon Q.

Sometimes early handedness before 1 year of life, or a visual gaze preference that looks as if the child is gazing at people with his or her head turned to one side, may be an important sign that a young child has Sturge-Weber syndrome brain involvement. Parents have reported bringing these clues to the attention of their pediatrician, only to be told that everything is okay. More commonly, the...

Sturge –Weber syndrome (SWS) or encephalotrigeminal angiomatosis is a sporadic,congenital phakomatosis of unknown etiology.Diagnosed by the triad of facial port wine stain(PWS) in the trigeminal nerve distribution, leptomeningeal venous angiomatosis ,and glaucoma. Bilateral Sturge-Weber Syndrome is a rare entity. We present in this report a rare case of bilateral SWS type II , with PWS involvin...

We’re back in the Milgrom-Weber affiliated interdependent values model. Today, we’re going to compare first-price to ascending auctions. Milgrom and Weber spend a bunch of time and notation demonstrating the existence of a symmetric equilibrium in the first-price auction. For our purposes, we’re going to just accept that it exists, since we don’t need a closed-form expression for bidding functi...

We characterize the set of perfect Bayesian equilibria in symmetric separating strategies in Milgrom and Weber’s (1982) model of English auctions. There is a continuum of such equilibria. The equilibrium derived by Milgrom and Weber is that in which bids are maximal. Only in the case of pure private values does a restriction to weakly undominated strategies select a unique equilibrium. This has...

Max Weber and Georg Simmel are considered as ideal-typical founders of sociology. Whereas Simmel pleaded for a large conception of sociology, which would include the epistemological and metaphysical issues as well, Max Weber explicitly excluded philosophical questions from the domain of sociology. A philosophical reading of Max Weber’s sociology, which uncovers his philosophy in the margins of ...
