the answer is relative—it depends on how big the circle is, of which the arcsecond is a part. For example, encoder disks come in several common sizes, including 1-inch and 2-inch disks. As the disks get smaller, the distance (arclength) spanned by each measurement—degree, arcminute,...
Second (Angle) In subject area: Engineering The solar azimuth is the second angle used to define the exact position of the Sun. Solar azimuth angle is defined as the angle between the projection of Sun’s centre onto the horizontal plane and due south direction. From: Concentrating Solar Powe...
We present the results of a high angular resolution (1.1 arcsec) and sensitivity (maximum of 0.1 mJy) radio survey at 1–2 GHz in the Galactic Bulge. This complements the X-ray Chandra Galactic Bulge Survey, and investigates the full radio source population in this dense Galactic region. ...

Fig. 1: iBCI system for dexterous finger movements. a, A computer display is placed in front of the participant so that he can perform a finger task with a virtual hand. During closed-loop control, the electrical activity from the array is mapped to a control signal for the virtual fin...
The angle rotation coils have an important property of quadrilaterals. The coefficient P in Eq. 5.2d is: P=(x3−x4)(y1−y2)−(x1−x2)(y3−y4) As P is a geometric function, we can demand that all P values in the triple quadrilaterals will be zero so that the ARC coil ...
The arc length of the centerline, s, is related to the angle θ by s = Rcθ where Rc is the radius of curvature. The arc length at a distance y > 0 from the centerline is written as sy = (Rc + y)θ. Before deformation, this line element also had the same length as the cente...
