Calibration of a white light interferometer for the measurement of micro-scale dimensions
Calibration is central to most measurement procedures. This is especially true in those cases where a large number of difficult-to-identify and difficult-to-control factors hinder the experimenters in their efforts to obtain...
Uncertainty due to experimental conditions in co-ordinate measuring machines
Any measurement method of a physical quantity cannot provide an exact unequivocal result owing to the infinite amount of information necessary to characterize fully both the physical quantity to be measured and the measuring...
Sources of variability in the set-up of an Indoor GPS
An increasing demand for an extended flexibility to model types and production volumes in the manufacture of large-size assemblies has generated a growing interest in the reduction of jigs and fixtures deployment during assembly...

The Characterization of Zn Hydrolase Using De Novo Due Ferri Single Chain (DFsc) Proteins
Joseph Pantel
Jan 01, 0001
Many natural enzymes can be found in nature that contain a metal ion. These enzymes have the potential for becoming new drugs and further biotechnology, but not all of the metalloenzymes' functions are fully understood. Through...

Quasi-Monte Carlo and Multilevel Monte Carlo Methods for Computing Posterior Expectations in Elliptic Inverse Problems
We are interested in computing the expectation of a functional of a PDE solution under a Bayesian posterior distribution. Using Bayes's rule, we reduce the problem to estimating the ratio of two related prior expectations. For a...

Anytime Monte Carlo
Abstract
Monte Carlo algorithms simulates some prescribed number of samples, taking some random real time to complete the computations necessary. This work considers the converse: to impose a...
Sphere Encapsulated Monte Carlo
We introduce a simple global optimization approach that is able to find minimum energy configurations of clusters containing aromatic molecules. The translational and rotational perturbations required in Monte Carlo-based...
DNA Cleavage Activity of de novo Designed Due Ferri Single Chain (DFsc) Proteins
Alana Huynh

Analysis of reported error in Monte Carlo rendered images.
Evaluating image quality in Monte Carlo rendered images is an important aspect of the rendering process as we often need to determine the relative quality between images computed using different algorithms and with varying...
Spin correlations in Monte Carlo simulations.
P Richardson
Feb 17, 2010
We show that the algorithm originally proposed by Collins and Knowles
for spin correlations in the QCD parton shower can be used in order to include spin
correlations between the production and decay of heavy particles in Monte...

Transitions between imperfectly ordered crystalline structures
Nigel Wilding
Jan 01, 0001
A model for two-dimensional colloids confined laterally by “structured boundaries” (i.e., ones that impose a periodicity along the slit) is studied by Monte Carlo simulations. When the distance D between the confining walls is...
Adversarial Monte Carlo Denoising with Conditioned Auxiliary Feature Modulation
Denoising Monte Carlo rendering with a very low sample rate remains a major challenge in the photo-realistic rendering research. Many previous works, including regression-based and learning-based methods, have been explored to...
SCONE
Over the last decade, the importance of the Monte Carlo as a neutron transport calculation method has greatly increased. This paper describes a Monte Carlo particle transport framework SCONE, which aims to provide with...

Parton distributions with scale uncertainties
Abstract
We present the MCscales approach for incorporating scale uncertainties in parton distribution functions (PDFs). The new methodology builds on the...
Continuous Level Monte Carlo and Sample-Adaptive Model Hierarchies
In this paper, we present a generalization of the multilevel Monte Carlo (MLMC) method to a setting where the level parameter is a continuous variable. This continuous level Monte Carlo (CLMC) estimator provides a natural...
