Beam Misalignments and Fluid Velocities in Laser-Induced Thermal Acoustics [PDF]
, 1999 Beam misalignments and bulk fluid velocities can influence the time history and intensity of laser-induced thermal acoustics (LITA) signals. A closed-form analytic expression for LITA signals incorporating these effects is derived, allowing the magnitude

Axion Kinetic Misalignment Mechanism [PDF]
Physical Review Letters, 2020 In the conventional misalignment mechanism, the axion field has a constant initial field value in the early universe and later begins to oscillate. We present an alternative scenario where the axion field has a nonzero initial velocity, allowing an axion decay constant much below the conventional prediction from axion dark matter.

Misalignment Calculation on Off-Axis Telescope System via Fully Connected Neural Network
IEEE Photonics Journal, 2020 On the process of alignment for pupil off-axis telescope system, the determination of decentering and tilt misalignments is a key step. In this paper, we proposed a new method which adopts the fully connected neural network (FCNN) as a fitting tool to ...

Bootstrapping the Coronal Magnetic Field with STEREO: I. Unipolar Potential Field Modeling [PDF]
, 2010 We investigate the recently quantified misalignment of $\alpha_{mis} \approx 20^\circ-40^\circ$ between the 3-D geometry of stereoscopically triangulated coronal loops observed with STEREO/EUVI (in four active regions) and theoretical (potential or ...

Geometric Parameters Estimation and Calibration in Cone-Beam Micro-CT
Sensors, 2015 The quality of Computed Tomography (CT) images crucially depends on the precise knowledge of the scanner geometry. Therefore, it is necessary to estimate and calibrate the misalignments before image acquisition.

The use of orbitals and full spectra to identify misalignment [PDF]
, 2014 In this paper, a SpectraQuest demonstrator is used to introduce misalignment in a rotating set-up. The vibrations caused by misalignment is measured with both accelerometers on the bearings and eddy current probes on the shaft itself.
