Trapezoidal Pulse

This paper first establishes the model for a 2-DOF non-linear cushion packaging system with strong hysteresis and then derives its vibration equations. The vibration equations are transformed into ones using dimensionless variables and parameters. The influence of mass ratio and stiffness ratio on the system under excitation of trapezoidal pulse shock has been analyzed based on the response spectra obtained by applying the fourth order Runge-Kuntta method to the transformed equations. Results show that the mass ratio is the key design parameter.

We present some new exact expressions for the contribution of the mass-dependent three-bubble diagrams to the anomalous magnetic moment of leptons L = e, µ and τ. A comparison with the analytic expansions in terms of the mass ratio mℓ/mL made in the literature, whenever relevant, is discussed.

AbstractWe present TreeFrog, a massively parallel halo merger tree builder that is capable comparing different halo catalogues and producing halo merger trees. The code is written in c++11, use the MPI and OpenMP API’s for parallelisation, and includes python tools to read/manipulate the data products produced. The code correlates binding energy sorted particle ID lists between halo catalogues, determining optimal descendant/progenitor matches using multiple snapshots, a merit function that maximises the number of shared particles using pseudo-radial moments, and a scheme for correcting halo merger tree pathologies. Focusing on VELOCIraptor catalogues for this work, we demonstrate how searching multiple snapshots spanning a dynamical time significantly reduces the number of stranded halos, those lacking a descendant or a progenitor, critically correcting poorly resolved halos. We present a new merit function that improves the distinction between primary and secondary progenitors, reducing tree pathologies. We find FOF accretion rates and merger rates show similar mass ratio dependence. The model merger rates from Poole, et al. [2017, 472, 3659] agree with the measured net growth of halos through mergers.
