Multibeam Energy Moments of Multibeam Particle Velocity Distributions [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2020
AbstractHigh‐resolution electron and ion velocity distributions, f(v), which consist of N effectively disjoint beams, have been measured by NASA's Magnetospheric Multiscale Mission and in reconnection simulations. Commonly used standard velocity moments assume a single mean‐flow velocity for the entire distribution.

On interferometric duality in multibeam experiments [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2003
We critically analyze the problem of formulating duality between fringe visibility and which-way information, in multibeam interference experiments. We show that the traditional notion of visibility is incompatible with any intuitive idea of complementarity, but for the two-beam case.

Challenges in the Multibeam Antennas [PDF]

open access: yes, 2018
In this project, we are trying to shed light on various aspects of the antenna arrays. Special focus is on solving the problems related to multibeam antennas. One traditional application of the multibeam antennas is sum and difference patterns.

Multi-Beam Scanning Electron Microscopy for High-Throughput Imaging in Connectomics Research

open access: yesFrontiers in Neuroanatomy, 2018
Major progress has been achieved in recent years in three-dimensional microscopy techniques. This applies to the life sciences in general, but specifically the neuroscientific field has been a main driver for developments regarding volume imaging.

A Storage-Saving Quadtree-Based Multibeam Bathymetry Map Representation Method

open access: yesJournal of Marine Science and Engineering, 2023
With the rapid advancement of the simultaneous localization and mapping (SLAM) technology, the collaboration of several autonomous underwater vehicles (AUVs) in large-scale seafloor imaging has become a trending topic. Electromagnetic waves are difficult

On the sensitivity of the capacity enhancement of a TDMA system with adaptive multibeam antennas [PDF]

open access: yes, 1997
The paper presents results for the likely capacity improvement when an adaptive multibeam antenna is used in conjunction with air interface parameters akin to the DCS1800 system.

Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO246 [PDF]

open access: yes, 2021
Multibeam data were collected during RV Sonne cruise SO246 (2016-02-01 – 2016-03-21). Multibeam sonar system was Kongsberg EM122. Data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting ...

msemalign: a pipeline for serial section multibeam scanning electron microscopy volume alignment

open access: yesFrontiers in Neuroscience, 2023
Serial section multibeam scanning electron microscopy (ssmSEM) is currently among the fastest technologies available for acquiring 3D anatomical data spanning relatively large neural tissue volumes, on the order of 1 mm3 or larger, at a resolution ...
