Purpose. Research on the mechanism of influence straightening conditions grinding wheel, including relative oscillations wheel and a multipoint diamond dresser, roughness ground surface other machining results. Methodology. Straightening with dresser is process high-speed destruction hard, abrasive material its bond under instantaneous forces, grains hard crystal. During straightening, total co...

A canonical straightening process is described for soliton curves associated with the localized induction hierarchy. Following computer animated examples, the present topic is placed in the context of a larger theme: the soliton class is a natural setting for representation of diverse topological and geometrical behavior of curves and their motions. The constructions we describe here pertain to...

We describe a straightening algorithm for the action of Sn on a certain graded ring Ru. The ring Ru, appears in the work of C. de Concini and C. Procesi [2] and T. Tanisaki [8], and more recently in the work of A. Garsia and C. Procesi [4]. This ring is a graded version of the permutation representation resulting from the action of Sn on the left cosets of a Young subgroup. As a corollary of ou...

In order to harness the kinetic energy of marine currents, we propose a novel ocean-current turbine with a horizontal axis. The turbine can be moored to the seabed and function similarly to kites in a water flow. To operate such turbines in a marine current, the resulting rotor torque needs to be canceled. Therefore, the proposed turbine is designed with a float at its top and a counterweight a...
