Research on Fault Diagnosis of Rolling Bearing Based on Morlet Wavelet and Scale Space
机车电传动, 2021 Aiming at the difficulty of extracting the early fault features of rolling bearings, a rolling bearing fault diagnosis method based on Morlet wavelet and scale space was proposed.

Operational definition of (brane induced) space-time and constraints on the fundamental parameters [PDF]
, 1999 First we contemplate the operational definition of space-time in four dimensions in light of basic principles of quantum mechanics and general relativity and consider some of its phenomenological consequences.

An Adaptive Method for Star Extraction from Digital Astronomical Images [PDF]
فصلنامه علوم و فناوری فضایی, 2010 Celestial positioning has been used for navigation purposes for many years. Stars as the extra-terrestrial benchmarks provide unique opportunity in absolute point positioning.

, 2003 We derive both Lagrangian and Hamiltonian mechanics as gauge theories of Newtonian mechanics. Systematic development of the distinct symmetries of dynamics and measurement suggest that gauge theory may be motivated as a reconciliation of dynamics with ...

Can noncommutativity resolve the Big-Bang singularity? [PDF]
, 2003 A possible way to resolve the singularities of general relativity is proposed based on the assumption that the description of space-time using commuting coordinates is not valid above a certain fundamental scale.

Considerations and Framework for Foveated Imaging Systems †
Photonics, 2018 Foveated sight as observed in some raptor eyes is a motivation for artificial imaging systems requiring both wide fields of view as well as specific embedded regions of higher resolution.

Exploring redshift-space distortions in large-scale structure
, 2018 We explore and compare different ways large-scale structure observables in redshift-space and real space can be connected. These include direct computation in Lagrangian space, moment expansions and two formulations of the streaming model.
