in this study an empirical model which can be used to predict the rutting parameter (g*/sinδ) for neat and powder rubber modified bitumen describes. the model was developed using 36 unique powder rubber modified bitumen combinations, rubber concentrations were varied at 5% intervals between 5 and 20%. the effects of powder rubber particle size on model accuracy were also studied ultimately a mo...

We perform Monte Carlo simulations using the Wolff cluster algorithm of multiple q = 2, 3, 4 state Potts models on dynamical phi-cubed graphs of spherical topology in order to investigate the c > 1 region of two-dimensional quantum gravity. Contrary to naive expectation we find no obvious signs of pathological behaviour for c > 1. We discuss the results in the light of suggestions that have bee...

two models are commonly made use to explain the behavior of insurance industries, namely: risk-pooling and the risk-absorbing models. neither of the two models provides an acceptable definition of insurance output in the economies experiencing high inflation rate. to address the deficiencies of the present models, an alternative was proposed in the current study as based on the theory of in...

in this paper, we try and valuate preemption rights by modifying the black-scholes model, which is widely used to valuate options and other derivatives. here we first present the basics of the black-scholes model and then we discus modification of the model to be fit for preemption right valuation. at the end, we valuate four of the preemptive rights using the proposed model

We show that addition of Metropolis single spin flips to the Wolff cluster-flipping Monte Carlo procedure leads to a dramatic increase in performance for the spin-1/2 Ising model. We also show that adding Wolff cluster flipping to the Metropolis or heat bath algorithms in systems where just cluster flipping is not immediately obvious (such as the spin-3/2 Ising model) can substantially reduce t...

We have measured the autocorrelations for the Swendsen-Wang and the Wolff cluster update algorithms for the Ising model in 2, 3 and 4 dimensions. The data for the Wolff algorithm suggest that the autocorrelations are linearly related to the specific heat, in which case the dynamic critical exponent z int,E = α/ν. For the Swendsen-Wang algorithm, scaling the autocorrelations by the average maxim...

A consensus appears to have emerged in the literature that per capita income levels and/or levels of productivity in the industrialized market economies have converged significantly over the last century, and especially since the end of the second world war (see, e.g., Abramovitz, Baumol, Baumol and Wolff, De Long, Dollar and Wolff, Dowrick and Nguyen). The results of Abramovitz and Baumol, in ...

With a nonequilibrium relaxation method, we calculate the dynamic critical exponent z of the two-dimensional Ising model for the SwendsenWang and Wolff algorithms. We examine dynamic relaxation processes following a quench from a disordered or an ordered initial state to the critical temperature Tc, and measure the exponential relaxation time of the system energy. For the Swendsen-Wang algorith...
