A wide column test of a composite isogrid panel subjected to quasi-static, axial compression is modeled with a hybrid-static dynamic computational method. The data from the test panel exhibited discontinuous responses in the compressive load for slowly increased end-shortening. The computational model was developed to corroborate these discontinuities with the phenomenon of mode jumping. Mode j...

The prepupation caterpillar of the Southeast Asian moth Calindoea trifascialis constructs a leaf shelter that jumps across the ground using a jumping method novel among the insects. We found that movement path direction was correlated to the direction opposite to the most intense light. Correlated random walk (CRW) analyses found net squared displacements higher than predicted by a CRW, and fra...

At first, there were explosions. Neurobiologists investigating the peculiar behavior of the jumping spider sought to record its neurons. But the scientists’method always spelled doom for the creatures: peeling back the spiders’ exoskeleton to expose the brain caused vital fluids to burst forth. For decades, neurobiologists and ecologists have struggled to understand just how the poppy seed-size...

[1] Seismic hazard analysis relies heavily on the segmentation of faults. The ability of ruptures to break multiple segments has a big impact on estimated hazard. Current practice for estimating multiple segment breakage relies on panels of experts voting on their opinions for each case. Here, we explore the probability of elastodynamic ruptures jumping segment stepovers in numerical simulation...

Linear recurring sequences with very large periods are widely used as the basic building block of pseudorandom number generators. In many simulation applications, multiple streams of random numbers are needed, and these multiple streams are normally provided by jumping ahead in the sequence to obtain starting points that are far apart. For maximal-period generators having a large state space, t...

Child running and jumping sound are one of the major noise sources in heavy structured apartment building. It was reported that physical characteristics of rubber ball (heavy/soft impact sound) was similar with child's running and jumping. As a standard impact source, rubber ball was standardized in ISO 10140 series and ISO 16283-2. However, evaluation method of rubber ball was not proposed in ...

In this paper we explore lattice-based position-jump models of diffusion, and the implications of introducing non-local jumping; particles can jump to a range of nearby boxes rather than only to their nearest neighbours. We begin by deriving conditions for equivalence with traditional local jumping models in the continuum limit. We then generalize a previously postulated implementation of the R...
