Open‐Source Tools for Building Data‐Driven, Sovereignty‐Permitting Web Apps
Journal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.Public domain or access‐controlled web apps provide a simple and relatively cheap way to increase the accessibility of information within data resources. Modern data environments, especially those subject to Māori Data Sovereignty (MDSov) constraints, face technical challenges balancing data security and privacy with accessibility and collective ...

MULTI-PULSE CHAOTIC MOTION FOR A NON-AUTONOMOUS BUCKLED PLATE BY USING THE EXTENDED MELNIKOV METHOD [PDF]
, 2020 The multi-pulse Shilnikov orbits and chaotic dynamics for a parametrically excited, simply supported rectangular buckled thin plate are studied by using the extended Melnikov method. Based on von Karman type equation and the Galerkin's approach, two-

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Melnikov method for autonomous Hamiltonians
, 1996 The web page contains both the dvi and postscript version of the paper. This paper presents the method of applying the Melnikov method to autonomous Hamiltonian systems in dimension four. Besides giving an application to Celestial Mechanics, it discusses the problem of convergence of the Melnikov function and the derivative of the Melnikov function.

A Single and Double Mode Approach to Chaotic Vibrations of a Cylindrical Shell with Large Deflection
Shock and Vibration, 2004 The chaotic vibrations of a cylindrical shell of large deflection subjected to two-dimensional exertions are studied in the present research. The dynamic nonlinear governing equations of the cylindrical shell are derived on the basis of single and double
