Influence of edge slotting of magnet pole with fixed slot opening width on the cogging torque in inset permanent magnet synchronous machine

open access: yesAdvances in Mechanical Engineering, 2016
The cogging torque in an inset permanent magnet synchronous machine causes some undesirable vibration and noises which should be reduced in the earliest possible stage of design.

Extracting physical observables using macroscopic ensemble in the spex-mixer/mill simulation

open access: yes, 2009
A technique to simulate the spex-mixer/mill system as a macroscopic ensemble rather than a pure dynamical system is proposed. The treatment is suitable especially for comminution processes generating the nanomaterial up to nanometers scale where the ...

Morfo-metafonia e vocalismo marginale nei dialetti salentini settentrionali

open access: yesAtti del Sodalizio Glottologico Milanese
The northern Salentino vowel system, provided with five stressed vowels, is nowadays conceived as an original Sicilian system, later influenced by the Neapolitan one. Indeed, each of the two mid vowels shows two different metaphonic outcomes (/ɛ‒MET/ ~ /
