Visualization of Molecular Transport by the DSMC Method

Journal of the Visualization Society of Japan, 1996
Rarefied gas flows through the circular tubes with a finite length were numerically simulated by the Direct Simulation of Monte Carlo method. The effects of boundary conditions, such as accommodation coefficients and surface temperatures at the solid surfaces of the tubes are discussed.

Methods for implementing the stream boundary condition in DSMC computations [PDF]

International Journal for Numerical Methods in Fluids, 2003
AbstractIn the direct simulation Monte‐Carlo (DSMC) method for simulating rarefied gas flows, the velocities of simulator particles that cross a simulation boundary and enter the simulation space are typically generated using the acceptance–rejection procedure that samples the velocities from a truncated theoretical velocity distribution that excludes ...

Multiscale simulation of interacting turbulent and rarefied gas flows in the DSMC framework

Theoretical and Applied Mechanics Letters
A multiscale stochastic-deterministic coupling method is proposed to investigate the complex interactions between turbulent and rarefied gas flows within a unified framework.

Agar‐Based Optical Sensing System With a Phosphorescent Grid Pattern for Measuring Stress Distributions of Root Growth Using the Sampling Moiré Method

Advanced Materials Technologies, EarlyView.
This paper presents an agar medium with a phosphorescent grid pattern that measures the stress distribution generated by growing plant roots. Using phosphorescence, the system optically separates the grid pattern from the root and extracts the grid deformation.

Sinusoidal Microchannel with Descending Curves for Varicose Veins Implantation

Micromachines, 2018
Approximately 26% of adult people, mostly females, are affected by varicose veins in old age. It is a common reason for distress, loss of efficiency, and worsening living conditions.

Depth of Invasion Predicts Vocal Fold Motility and Muscle Invasion in Glottic Carcinoma

The Laryngoscope, EarlyView.
To determine whether depth of invasion (DOI) provides an objective surrogate for vocal fold motility and vocal muscle invasion in glottic squamous cell carcinoma. Methods and Results: In derivation and external validation cohorts, radiologic DOI strongly correlated with pathologic DOI and accurately predicted altered vocal fold motility and muscle ...

Sex Steroids Measurement by Mass Spectrometry in Hypogonadal Men in a Real‐World Setting: Serum Estradiol (E2) and E2 to Total Testosterone Ratio Do Not Differ Between Patients With Klinefelter Syndrome and Non‐Klinefelter Syndrome Hypogonadism

Andrology, EarlyView.
ABSTRACT Background Traditionally, Klinefelter syndrome (KS) was considered a clinical condition associated with hyperestrogenism. Aim To compare circulating sex steroids, particularly estrogens, in a cohort of KS and non‐KS hypogonadal men. Materials and Methods A cohort of hypogonadal men, treated and untreated, was prospectively enrolled in a real ...

DSMC: A Novel Distributed Store-Retrieve Approach of Internet Data Using MapReduce Model and Community Detection in Big Data

International Journal of Distributed Sensor Networks, 2014
The processing of big data is a hotspot in the scientific research. Data on the Internet is very large and also very important for the scientific researchers, so the capture and store of Internet data is a priority among priorities.

A Two Degree of Freedom Approach for Discrete‐Time Sliding Mode Control

International Journal of Robust and Nonlinear Control, Volume 36, Issue 13, Page 6540-6551, 10 September 2026.
ABSTRACT This paper proposes a new two degree of freedom (2‐DOF) framework for discrete‐time sliding mode control (DSMC) that decouples the disturbed evolution from its nominal counterpart. The novel nominal/disturbed subsystem separation for DSMC can be used to define multiple closed‐loop specifications. The nominal regulation (or tracking) controller
