A Lensed Arc in the Low Redshift Cluster Abell 2124
, 1998 We report the discovery of an arc-like object 27" from the center of the cD galaxy in the redshift $z=0.066$ cluster A2124. Observations with the Keck II telescope reveal that the object is a background galaxy at $z=0.573$, apparently lensed into an arc ...

Sensor Fusion to Estimate the Depth and Width of the Weld Bead in Real Time in GMAW Processes
Sensors, 2018 The arc welding process is widely used in industry but its automatic control is limited by the difficulty in measuring the weld bead geometry and closing the control loop on the arc, which has adverse environmental conditions.
