The stick-to-slip transition of a fingertip in contact with a planar surface does not occur instantaneously. As the tangential load increases, portions of the skin adhere while others slip, giving rise to an evolution of the contact state, termed partial slip. We develop a quasi-static model that predicts that if the coefficient of kinetic friction is larger than the coefficient of static frict...

This paper is an introduction to a workshop on electrodes location and specific exercises. Selectivity of EMG electrodes depends on their interspacing, their conductive area and axis direction with respect to the direction of the underlying muscular fibres. Minimal cross talk area (MCA) helps to limit or avoid crosstalk from neighbouring muscles. We present examples of MCA and typical sEMG patt...

nowadays, many antibiotics are being used to control infectious diseases. inappropriate use of antibiotics leads to emergence of resistant bacteria and problems such as a prolonged course of treatment. medicinal plants and their derivatives, as a good source of treatment, are effective against drug resistance. in this study we have evaluated the antimicrobial activity of herbal essential oils o...

We consider the methods of construction simple polygons for a set S of n points and applying them for searching the minimal area polygon. In this paper we propose the approximate algorithm, which generates the simple polygonalizations of a fixed set of points and finds the minimal area polygon, in O (n) time and using O(n) memory. Keywords—simple polygon, approximate algorithm, minimal area pol...
