The main function included in the attached file is called FRAME. The algorithm implemented in this function can be useful in motion analysis (biomechanics, bioengineering).When you know the 3-D position of at least three non-collinear points, you can define a Cartesian reference frame (coordinate...

Paired proportions have traditionally been compared using McNemar's test but an exact alternative due to Liddell is preferable. the usual reason for using approximate methods, when exact methods are available, is that the former are "quick" if sometimes "dirty". There is no such justification in...

Memory resistor or memristor is a nonlinear, fourth basic, passive element beside on conventional elements, R, L and C. Memristor was discovered by L.O. Chua in 1971, but it has been aroused recently by researchers at HP Labs. It is expected to make a huge change not only in literatures but also...

A common technique for removing noise from images is by blur-ring them with a weighted mean or a Gaussian filter. Through theseprocesses noise reduction is achieved, but unfortunately, valuableinformation is lost and the details of object boundaries aredeformed. A solution to this problem,...

Bonferroni-Holm (1979) correction for multiple comparisons. This is a sequentially rejective version of the simple Bonferroni correction for multiple comparisons and strongly controls the family-wise error rate at level alpha. It works as follows:1) All p-values are sorted in order of smallest to...
