Examples of Isoptic Ruled Surfacesangent planes, we can ask for pairs of tangent planes that enclose a fixed angle .. The lines of intersection of all such pairs of tangent planes will then be defined as the . . of .. Especially, if ., we shall call . the .. We shall give some general results on isoptic ruled surfaces together with some examples.

A One-Parameter Family of Triangle Cubicspolars of the inflection points are the medians of the base triangle. We shall study especially those cubics that are defined by triangle centers. Each triangle center defines its own distance product cubic and, in contrast to all other known triangle cubics, only a rather small number of centers share their cubic.

Interactive 4-D Visualization of Stereographic Images from the Double Orthogonal Projectioneographic image. Furthermore, we show an application to a synthetic construction of a spherical inversion and visualizations of double orthogonal projections and stereographic images of Hopf tori on a 3-sphere generated from Clelia curves on a 2-sphere.

Muscle fatigue has been shown to be one of the most important biofeedback parameters of EMG in rehabilitation, ergonomics and training, by using measured results from the body to change the way we behave, improve our performance and
