Three-cylinder gasoline engines are increasingly favored by major automobile manufacturers due to their good fuel economy, low manufacturing cost and consumption. However, the inherent balance problem has an adverse effect on vibration of whole engine even comfort vehicle, which limits its application in high-end models. This paper studied dynamics characteristic flexible multi-body system thre...

Variations of k-d trees represent a fundamental data structure used in Computational Geometry with numerous applications in science. For example particle track fitting in the software of the LHC experiments, and in simulations of N-body systems in the study of dynamics of interacting galaxies, particle beam physics, and molecular dynamics in biochemistry. The many-body tree methods devised by B...

Distinct motor programs can be coupled to refine the repertoire of behavior dynamics. However, mechanisms underlying such coupling are poorly understood. The defecation motor program (DMP) of C. elegans is composed of a succession of body contraction and expulsion steps, performed repeatedly with a period of 50-60 sec. We show that recurring patterns of directed locomotion are executed in tande...

The neck and spinal cord injuries associated with both traffic and sports accidents have tremendous socioeconomic effects on human quality of life. Validated computational models capable of predicting the neck response under impact loads are invaluable tools to evaluate strategies and preventive measures for head-first impact. A three-dimensional multi-body dynamics model of an existing experim...

We propose a novel biologically inspired framework for the recognition of human full-body actions. First, we extract body pose and motion features from depth map sequences. We then cluster pose-motion cues with a two-stream hierarchical architecture based on growing neural gas (GNG). Multi-cue trajectories are finally combined to provide prototypical action dynamics in the joint feature space. ...

Multi-spins tunneling cross-relaxations in an ensemble of weakly-coupled Ho 3+ ions, mediated by weak anisotropic dipolar interactions, can be ev-idenced by ac-susceptibility measurements in a high temperature regime. Based on a four-body representation, including the rare-earth nuclear spin, two-ions tunneling mechanisms can be attributed to both dipolar-biased tun-neling and co-tunneling proc...
