Single Event Effect cross section calibration and application to quasi-monoenergetic and spallation facilities

open access: yesEPJ Nuclear Sciences & Technologies, 2018
We describe an approach to calibrate Single Event Effect (SEE)-based detectors in monoenergetic fields and apply the resulting semi-empiric responses to more general mixed-field cases in which a broad variety of particle species and energy spectra are ...

Bayesian Adaptive Hamiltonian Monte Carlo with an Application to High-Dimensional BEKK GARCH Models [PDF]

open access: yes
Hamiltonian Monte Carlo (HMC) is a recent statistical procedure to sample from complex distributions. Distant proposal draws are taken in a equence of steps following the Hamiltonian dynamics of the underlying parameter space, often yielding superior ...

Derivative-Variance Hybrid Global Sensitivity Measure with Optimal Sampling Method Selection

open access: yesMathematics
This paper proposes a derivative-variance hybrid global sensitivity measure with optimal sampling method selection. The proposed sensitivity measure is as computationally efficient as the derivative-based global sensitivity measure, which also serves as ...

An Efficient Quasi-Monte Carlo Algorithm for High Dimensional Numerical Integration

open access: yesMathematics
In this paper, we develop a fast numerical algorithm, termed MDI-LR, for the efficient implementation of quasi-Monte Carlo lattice rules in computing d-dimensional integrals of a given function. The algorithm is based on converting the underlying lattice

Novel Strategy to Improve the Performance of Localization in WSN

open access: yesThe Scientific World Journal, 2015
A novel strategy of discrete energy consumption model for WSN based on quasi Monte Carlo and crude Monte Carlo method is developed. In our model the discrete hidden Markov process plays a major role in analyzing the node location in heterogeneous media ...

First- and quasi-second-order optimization algorithms in variational Monte Carlo

open access: yesPhysical Review Research
Many quantum many-body wavefunctions, such as Jastrow-Slater, tensor network, and neural quantum states, are studied with the variational Monte Carlo technique, where stochastic optimization is usually performed to obtain a faithful approximation to the ...

RPEM: Randomized Monte Carlo parametric expectation maximization algorithm

open access: yesCPT: Pharmacometrics & Systems Pharmacology
Inspired from quantum Monte Carlo, by sampling discrete and continuous variables at the same time using the Metropolis–Hastings algorithm, we present a novel, fast, and accurate high performance Monte Carlo Parametric Expectation Maximization (MCPEM ...
