Adaptively sampled particle fluids [PDF]

open access: yesACM SIGGRAPH 2007 papers, 2007
We present novel adaptive sampling algorithms for particle-based fluid simulation. We introduce a sampling condition based on geometric local feature size that allows focusing computational resources in geometrically complex regions, while reducing the number of particles deep inside the fluid or near thick flat surfaces.

Comparative genomics analysis of three conserved plasmid families in the Western Hemisphere soft tick-borne relapsing fever borreliae provides insight into variation in genome structure and antigenic variation systems

open access: yesMicrobiology Spectrum, 2023
Borrelia spirochetes, causative agents of Lyme disease and relapsing fever (RF), have uniquely complex genomes, consisting of a linear chromosome and both circular and linear plasmids. The plasmids harbor genes important for the vector-host life cycle of

Marine Adaptive Sampling Scheme Design for Mobile Platforms under Different Scenarios

open access: yesJournal of Marine Science and Engineering, 2022
Marine adaptive sampling is a technique that makes full use of limited observation resources by selecting the optimal positions. Recently, the design of an adaptive sampling scheme based on a mobile platform has become a research hotspot.

Efficiency of adaptive cluster sampling and traditional sampling for coastal mangrove in Hainan of China

open access: yesJournal of Forest Science, 2012
Based on two species of Coastal Mangrove in Hainan of China, Sonneratia Apetala Buch-Ham and Sonneratia caseoli, we estimated the density of the two species to evaluate the efficiency of adaptive cluster sampling (ACS), simple random sampling (SRS) and ...

Layered adaptive importance sampling [PDF]

open access: yesStatistics and Computing, 2016
Monte Carlo methods represent the "de facto" standard for approximating complicated integrals involving multidimensional target distributions. In order to generate random realizations from the target distribution, Monte Carlo techniques use simpler proposal probability densities to draw candidate samples.

State-of-the-Art and Comparative Review of Adaptive Sampling Methods for Kriging

open access: yesArchives of Computational Methods in Engineering, 2020
Metamodels aim to approximate characteristics of functions or systems from the knowledge extracted on only a finite number of samples. In recent years kriging has emerged as a widely applied metamodeling technique for resource-intensive computational ...
