Three members of the same family with hereditary congenital nystagmus (eN) were studied. Nystagmus amplitude, fre­ quency, and Intensity functions deter­ mined the gaze angle with least nys­ tagmus. Visual acuity was increased in all cases by the use of version or composite prisms. In both pendular and jerk forms of eN, the fovea oscillated on alternate sides of the fixation spot and exhibited ...

Both path and speed planning play key roles in automated driving, specially when a certain comfort level is required. This paper proposes human-like method for already defined paths while minimizing travel time. The proposed able to compute time-optimal profile that meet the given constrains with regard speed, acceleration jerk. For this purpose, an initial acceleration-limited approach introdu...

Feedrate scheduling is one of the most critical technologies in CNC machining, requiring a reasonable balance between efficiency and quality. This paper proposes jerk-continuous feedrate smoothing (JCFS) method to generate low-vibration smooth profile for non-uniform rational B-spline (NURBS) interpolation. Firstly, segmentation concept introduced subdivide entire trajectory into segments accom...

fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

Our fundamental lack of understanding of the acceleration of the Universe suggests that we consider a kinematic description. The simplest formalism involves the third derivative of the scale factor through a jerk parameter. A new approach is presented for describing the results of astronomical observations in terms of the contemporary jerk parameter and this is related to the equation of state ...
