This work measures the time to equilibrium for the multicanonical method on the 2DIsing system by using a new criterion, proposed here, to find the time to equilibrium, teq, of any sampling procedure based on a Markov process. Our new procedure gives the same results that the usual one, based on the magnetization, for the canonical Metropolis sampling on a 2D-Ising model at several temperatures...

In 2010, Jain et al. [JJUW10] provided the first proof that QIP=PSPACE. Jain et al. used a constructive argument which applied the matrix multiplicative weight update method to a semidefinite programming problem formulation of a QMAM protocol to achieve this proof. The proof that QIP= PSPACE was alternately characterized by Xiaodi Wu [Wu10] that same year; Xiaodi Wu’s method, however, was simpl...

by proposing a predictive method with no adjustable parameter and by using infinite dilution activity coefficients of components in binary mixtures obtained from unifac model, the binary interaction parameters (k12) in van der waals mixing rule (vdwmr) and orbey-sandler mixing rule (osmr) have been evaluated. the predicted binary interaction parameters are used in peng-robinson-stryjek-vera equ...

Using some recent results from nonsmooth analysis, we prove the convergence of a new iterative scheme to a solution of a nonconvex equilibrium problem.

inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...
