Smarticles: A Method for Identifying and Correcting Instability and Error Caused by Explicit Integration Techniques in Physically Based Simulations
<p>Using an explicit integration method in physically based animations has many advantages including conceptual and computational simplicity, however, it re- quires small time steps to ensure low numerical instability. Simulations with large numbers of individually interacting components such as …

Análise dinâmica não-linear de sistemas rígido-flexíveis
… advantageous to treat each region by implicit or explicit algorithms implemented in the same computational program. The objective of the present work is to study a mixed time integration algorithm applied to non-linear problems. The explicit integration is obtained by the Central Difference …

The application of phasor measurements for adaptive protection and control
… direct method which determines stability without explicit integration techniques is applicable in this study. The results of the system stability prediction in real-time by digital computer simulation under stable and unstable operating conditions are presented.

Advances in structure and small molecule docking predictions for crystallized G-Protein coupled receptors
… to transmembrane proteins, which requires an explicit integration of the lipid bilayer into the loop prediction calculation. In the initial work, this new approach to loop prediction yields highly accurate 3-dimensional structures of the intra and intercellular loops of four G-protein coupled …

Computational framework for simulating the deformation and fracture response of oligocrystalline shape memory alloys
… by Thamburaja and Anand (2001) and a robust explicit integration scheme is developed to update the constitutive law. In order to investigate the effects the grain boundary characteristics have on the martensitic phase transformation and transformation-induced fracture, finite element …

The response of impulsively loaded sandwich plates
… strain energy absorbed are also discussed. The explicit integration scheme is considered the best finite element solution method to use for this dynamic response problem. The pressure loading model is found to give the best correlation with experimental data while velocity loading models tend to …

Modelling of friction stir spot welding
… at the tool to workpiece interface without an explicit statement of the friction law. Marker experiments are presented which use dissimilar composition but similar strength alloys to visualise flow patterns. The layering behaviour and surface patterns observed in the model agree well with …

Self-consistent dynamical and radiative models of low-luminosity active galactic nuclei
… with low to moderate optical depths and our explicit integration scheme will only be efficient for relativistic flows. Fortunately, \bhlight\ should be well suited to studying the weakly radiative LLAGN. Though we plan to test \bhlight\ more extensively in the future, I present two test …

Moment Matching and Modal Truncation for Linear Systems
While moment matching can effectively reduce the dimension of a linear, time-invariant system, it can simultaneously fail to improve the stable time-step for the forward Euler scheme. In the context of a semi-discrete heat equation with spatially smooth forcing, the high frequency modes are …

A long-term study of educational robotics and achievement in math and science
In recent years, educational robotics has become a popular tool in STEM programs, such as afterschool clubs, and summer camps, as well as classrooms. However, the research on the benefits of robotics have shown mixed results. In addition, many of the studies lack strong controls and focus on …
