Long-term dynamic stability of discrete dislocations in graphene at finite temperature
We present an assessment of the finitetemperature dynamical stability of discrete dislocations in graphene. In order to ascertain stability, we insert discrete dislocation quadrupole configurations into molecular dynamics calculations as initial conditions. In calculations we use Sandia National Laboratories Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) and the Adaptive Int...
متن کاملGyrokinetic Simulation of Energetic Particle Turbulence and Transport
The fully self-consistent simulation of energetic particle turbulence and transport in burning plasmas such as ITER must incorporate three new physics elements: (i) kinetic effects of thermal particles at the thermal ion gyroradius (micro scale), (ii) nonlinear interactions of many meso scale (energetic particle gyroradius) shear Alfvén waves induced by the kinetic effects at the micro scale, a...
متن کاملHomogenization of regional river dynamics by dams and global biodiversity implications.
Global biodiversity in river and riparian ecosystems is generated and maintained by geographic variation in stream processes and fluvial disturbance regimes, which largely reflect regional differences in climate and geology. Extensive construction of dams by humans has greatly dampened the seasonal and interannual streamflow variability of rivers, thereby altering natural dynamics in ecological...
متن کامل3-RPS Parallel Manipulator Dynamical Modelling and Control Based on SMC and FL Methods
In this paper, a dynamical model-based SMC (Sliding Mode Control) is proposed fortrajectory tracking of a 3-RPS (Revolute, Prismatic, Spherical) parallel manipulator. With ignoring smallinertial effects of all legs and joints compared with those of the end-effector of 3-RPS, the dynamical model ofthe manipulator is developed based on Lagrange method. By removing the unknown Lagrange multipliers...
متن کاملSimulating Subsurface Flow and Transport on Ultrascale Computers using PFLOTRAN
We describe PFLOTRAN, a recently developed code for modeling multi-phase, multicomponent subsurface flow and reactive transport using massively parallel computers. PFLOTRAN is built on top of PETSc, the Portable, Extensible Toolkit for Scientific Computation. Leveraging PETSc has allowed us to develop—with a relatively modest investment in development effort—a code that exhibits excellent perfo...
