High-precision estimates of critical quantities by means of improved Hamiltonians
نویسندگان
چکیده
Three-dimensional spin models of the Ising and XY universality classes are studied by a combination of high-temperature expansions and Monte Carlo simulations applied to improved Hamiltonians. The critical exponents and the critical equation of state are determined to very high precision.

A Review of Epidemic Forecasting Using Artificial Neural Networks
Background and aims: Since accurate forecasts help inform decisions for preventive health-careintervention and epidemic control, this goal can only be achieved by making use of appropriatetechniques and methodologies. As much as forecast precision is important, methods and modelselection procedures are critical to forecast precision. This study aimed at providing an overview o...
متن کاملGenetic Control of Fiber Yield and Quality in Kenaf (Hibiscus cannabinus L.)
The study was conducted to investigate the ge-netic basis of kenaf fiber yield and quality In two sets of generations derived from 1X51 x Gha-na07 and Gregg x Ghana07 crosses. Analysis of generation means using weighted least squares procedure was performed on stalk dry weight, bast percentage, days to flowering, plant height, and basal stalk diameter . Analysis of generation means revealed tha...
متن کاملCritical Path Method for Flexible Job Shop Scheduling Problem with Preemption
This paper addressed a Flexible Job shop Scheduling Problem (FJSP) with the objective of minimization of maximum completion time (Cmax) which job splitting or lot streaming is allowed. Lot streaming is an important technique that has been used widely to reduce completion time of a production system. Due to the complexity of the problem; exact optimization techniques such as branch and bound alg...
متن کاملDetermination of the Nonlinear Equation Coefficients for Flow through Coarse Alluvium Foundations
As a result of the limitations in the application of Darcy Law (V=ki) to linear-laminar flow regimes through porous media and due to the fact that in coarse alluviums, the Reynolds number may exceed its critical value, the so-called Laplas equation cannot be used for precise analyses of coarse granular foundations. A more general relationship is, therefore, required for such cases. However, a c...
