The flight of insects may look effortless but, as with any animal, their movements would be wildly uneven without an intricate system of neural signaling and muscle response to stabilize and steer the...
As Cyclone Ita hit northern Australia last weekend, a much slower collision occurred in the world’s longest-running lab project, The University of Queensland’s Pitch Drop Experiment.

Self-initialised Fermi-1 acceleration by pitch-angle re-scattering of solar wind ions reflected from the parallel termination shock
anomalous cosmic ray process governing pick-up ions solar wind ions
2009/5/27
In a recent kinetic calculation a rather high amount of reflected ions was shown to occur at the solar wind termination shock under a parallel magnetic field orientation. The fate of these reflected i...
The Statistical Evaluation of Directional Spectrum Estimates Derived from Pitch/Roll Buoy Data
Directional Spectrum Estimates Derived Pitch/Roll Buoy Data
2009/2/16
Estimates of the ocean wave directional spectrum may be extracted from observations of surface vertical acceleration and slope made with a pitch/roll buoy. The analysis requires the specification of a...
Multimodal Properties of the Surface-Wave Field Observed with Pitch-Roll Buoys During GATE
GARP Tropical Atlantic Experiment Surface-Wave Field Pitch-Roll Buoys
2009/2/5
A sophisticated analysis technique is applied to a subset of pitch-roll buoy data collected by the research vessels Gilliss and Quadra during the GARP Tropical Atlantic Experiment (GATE) in September ...
A Data-Adaptive Ocean Wave Directional-Spectrum Estimator for Pitch and Roll Type Measurements
Ocean Wave Directional-Spectrum Estimator Type Measurements
2009/1/21
A data-adaptive directional-spectrum estimator is developed for “point” measurement systems such as the pitch and roll buoy and slope array. This estimator, unlike the much employed unimodal cosine po...
An Eigenvector Method for the Calculation of Directional Spectra from Heave, Pitch and Roll Buoy Data
maximum likelihood eigenvector Directional Spectra
2009/1/9
An eigenvector (EV) method for the determination of directional spectra from heave, pitch and roll buoy data is presented. Both a direct and an iterative form (based on an algorithm by Pawka) of this ...
A Method for the Routine Analysis of Pitch-and-Roll Buoy Wave Data
Routine Analysis Pitch-and-Roll Buoy Wave Data directional energy distribution
2009/1/6
A simple, computationally efficient method is proposed as a standard procedure for the routine analysis of pitch-and-roll buoy wave data. The method yields four directional model-free parameters per f...

Implications of Unusual Pitch-Angle Distributions Observed by ISEE-1 and 2
High-energy particle distribution of spiral Angle ISEE satellites high-energy protons function
2017/3/23
Unusual energetic particle pitch angle distributions (PADs) were observed by the ISEE-1 and 2 satellites at 3 h MLT and a radial distance of about 10–15RE during the time period of 07:00-14:00 UT on 3...
The Pitch and the Pseudo Angle of Pitch of a Closed Piece of (k+1)-Dimensional Ruled Surface in R\nun
