On the six components of optical angular momentum [PDF]

open access: yes, 2011
In special relativity the angular momentum is a rank-two antisymmetric tensor with six independent components. Three of these are the familiar generators of spatial rotation, which for light have been studied at length.

Optimal Sculling Velocity Algorithms for the Gyros With Angular Rate Output

open access: yesIEEE Access, 2018
With the advance of gyro technology, modern gyros have two output types: angular rate or integrated angular rate. However, the conventional sculling velocity algorithms usually still adopt integrated angular rate/specific-force increments as algorithm ...

Generation and manipulation of laser beams carrying orbital angular momentum for classical and quantum information applications [PDF]

open access: yes, 2009
Light orbital angular momentum (OAM) has been recognized as a new promising resource for classical and quantum information applications. In contrast to the spin angular momentum, the OAM is an inherently multidimensional.

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

On the direction of Coriolis force and the angular momentum conservation

open access: yesRevista Brasileira de Ensino de Física
This paper presents a qualitative analysis of the Coriolis force direction using the conservation of angular momentum and comparing it with quantitative calculation. In order to understand the implications of the theoretical expression for Coriolis force,
