Collisional dynamics around binary black holes in galactic centers [PDF]
, 2001 We follow the sinking of two massive black holes in a spherical stellar system where the black holes become bound under the influence of dynamical friction. Once bound, the binary hardens by three-body encounters with surrounding stars.

Security Assessment and Hardening of Fog Computing Systems
2023 IEEE 34th International Symposium on Software Reliability Engineering Workshops (ISSREW), 2023 In recent years, there has been a shift in computing architectures, moving away from centralized cloud computing towards decentralized edge and fog computing. This shift is driven by factors such as the increasing volume of data generated at the edge, the growing demand for real-time processing and low-latency applications, and the need for improved ...

Finite element based surface roughness study for ohmic contact of microswitches [PDF]
, 2012 Finite element method (FEM) is used to model ohmic contact in microswitches. A determinist approach is adopted, including atomic force microscope (AFM) scanning real contact surfaces and generating rough surfaces with three-dimensional mesh.

Evolution of nonlocal damage in steel under cyclic straining [PDF]
, 2013 For high dynamic excitation, e.g. by earthquakes, the vibrations of steel structures lead to inelastic material behavior. Hystereses, developing under cyclic loading, are responsible for the dissipation of energy.

Key features of numerical models for the FE-simulation of deep tunnel advance by the NATM
Underground SpaceIn the present work, important aspects of time-dependent nonlinear 3D finite element (FE) models for deep tunnel advance by the New Austrian Tunneling Method (NATM), characterized by repeated sequences of excavation, securing, and idle periods, are ...

A novel indicator for kinematic hardening effect quantification in deep drawing simulation [PDF]
, 2019 Deep drawing simulation techniques reduce tool design costs and improve tool performance and reliability. In terms of strain hardening, mixed models capturing the kinematic effect are sometimes more accurate than isotropic models.
