Application of the DSMC Method to Particle Simulation
JAPANESE JOURNAL OF MULTIPHASE FLOW, 1994 もう既に聞き飽きた感もあるが、計算機環境の発達によりさまざまな現象が数値シミュレーションにより取り扱われるようになった。混相流のような複雑な流れに対しても、流動を数値シミュレーションにより再現する試みが果敢になされている。最近では、ワークステーションの大幅な能力向上に代表される計算機のダウンサイジングにより、このような数値シミュレーションがより身近なものとなりつつあるのではないだろうか。混相流は時間的および空間的にさまざまなスケールの現象を含んでいるが、計算機の演算能力と記憶容量の増大は、よりミクロな視点に基づくモデルに立脚した数値シミュレーションを可能にする。固気二相流の分野では現在、固体粒子群の運動を個々の粒子レベルでモデル化するラグランジュ型の数値計算が盛んに行われている ...

Decision‐making in dementia care: insights from Brazilian family caregivers
Alzheimer's &Dementia, Volume 21, Issue S4, December 2025.Abstract Background The aging population in Brazil reached 10.49% in 2022, with projections indicating growth to 25.49% by 2060. This demographic shift is associated with an increase in chronic diseases, including dementia—a progressive neurodegenerative condition. Family caregivers play a critical role in decision‐making, which becomes more complex as

Evaporation Boundary Conditions for the Linear R13 Equations Based on the Onsager Theory
Entropy, 2018 Due to the failure of the continuum hypothesis for higher Knudsen numbers, rarefied gases and microflows of gases are particularly difficult to model.

NRxx Simulation of Microflows with Shakhov Model
, 2011 In this paper, we propose a method to simulate the microflows with Shakhov model using the NRxx method developed in [4, 5, 6]. The equation under consideration is the Boltzmann equation with force terms and the Shakhov model is adopted to achieve the ...

Strength Training Versus Walking on the Fibromyalgia Impact: A Blinded Randomised Controlled Trial
Musculoskeletal Care, Volume 23, Issue 4, December 2025.ABSTRACT Objective To compare the effect of 24 sessions of progressive intensity strength training on the impact of fibromyalgia (primary outcome). Furthermore, we evaluated its effects on sleep, anxiety, depression, wind‐up mechanism, conditioned pain modulation, cutaneous sensory threshold, musculoskeletal performance, walking ability, perceived ...

Heated granular fluids: the random restitution coefficient approach
, 2001 We introduce the model of inelastic hard spheres with random restitution coefficient $\alpha$, in order to account for the fact that, in a vertically shaken granular system interacting elastically with the vibrating boundary, the energy injected ...

The rheology of dense, polydisperse granular fluids under shear
, 2004 The solution of the Enskog equation for the one-body velocity distribution of a moderately dense, arbitrary mixture of inelastic hard spheres undergoing planar shear flow is described. A generalization of the Grad moment method, implemented by means of a

Statistical Error in Particle Simulations of Hydrodynamic Phenomena
, 2002 We present predictions for the statistical error due to finite sampling in the presence of thermal fluctuations in molecular simulation algorithms. Specifically, we establish how these errors depend on Mach number, Knudsen number, number of particles ...
