Comprehensive Modeling of Acetone Clusters: QTAIM Analysis and QCE Study

Journal of Computational Chemistry, Volume 47, Issue 11, 30 April 2026.
A multiscale DFT‐QTAIM‐QCE approach links acetone cluster interactions to liquid‐phase behavior. Macroscopic thermodynamic and IR properties emerge from a dynamic equilibrium of small clusters. ABSTRACT In molecular research, comprehending the microscopic source of the macroscopic characteristics of polar aprotic solvents continues to be a significant ...

Modeling Stiffness and Damping in Rotational Degrees of Freedom Using Multibond Graphs [PDF]

, 2013
A contribution is proposed for the modeling of mechanical systems using multibond graphs. When modeling a physical system, it may be needed to catch the dynamic behavior contribution of the joints between bodies of the system and therefore to ...

An Explicit, Compact, and Rotation‐Agnostic Formulation for Equivalent Nodal Loads for Point‐Loaded Beams

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT In time‐marching dynamical simulations, treatment of contact forces in deformable bodies represented by finite element meshes requires a compromise between simulation fidelity and computational costs. External forces directly evaluated at the mesh nodes offer better computational performance at the cost of modelling fidelity.

Multibody Dynamics Model of a Human Hand for Haptics Interaction [PDF]

, 2008
In this paper we propose a strategy for modelling a human hand for Haptics interaction. The strategy consists in a parallel computing architecture that calculates the dynamics of a hand; this is accomplished by computing the dynamics of each finger in a ...
