Accuracy measurement and variance estimation

surfaces from diVraction experiments:

(with suitable scaling) should provide a natural parametrization for the curves in the scaling limit. We conjecture that this parametrization is also given by a type of fractal variation along the curve, and present Monte Carlo simulations to support this conjecture. Then we show by simulations

methods. For WordNet PITs and their perturbations, the performances of the structure-based PageRank, FloorRank, and the corpusbased Information Content criteria are studied in Monte Carlo experiment. It is shown that the proposed approach can be used for the ranking of taxonomy evaluation criteria. Index

The one dimensional Kondo lattice model is investigated using Quantum Monte Carlo and transfer matrix techniques. In the strong coupling region ferromagnetic ordering is found even at large band fillings. In the weak coupling region the system shows an RKKY like behavior. In recent years the Kondo

The two-dimensional Wigner crystals are studied with the variational quantum Monte Carlo method. The close relationship between the groundstate wavefunction and the collective excitations in the system is illustrated, and used to guide the construction of the ground-state wavefunction

We present Quantum Monte-Carlo results for various positron-electron systems. We discuss the energetics of the bound state of a positronium (Ps) with finite atomic systems: a massive point charge Z, hydrogen (H) and lithium (Li). We also analyze the screening cloud around the positron
