Creep-recovery and stress-relaxation experiments were performed on neat and Polymer Modified Asphalts (PMAs). Through these experiments it is possible to deeply analyze these viscoelastic materials, both in linear and nonlinear conditions. The investigated functions are the relaxation modulus, G, and…

Wandering is a universal feature of wind-tunnel generated vortices and it consists of abrupt displacements of the vortex core location. Rapid scanning measurements on the tip vortex generated from a NACA 0012 half-wing model were performed in order to achieve data…

In June of 1948, the Bell Telephone Laboratories announced and demonstrated publicly a semiconductor amplifier invented by Bardeen and Brattain, and coined for it the name “transistor”, a contraction of transfer-resistor. That transistor was a point-contact transistor that consisted of…
