TL;DR: In this paper, the authors show that a fractal number D can be associated with any profile or cartography, by processing a z ( x ) profile as would be done with a random motion x ( t ).
TL;DR: In this paper, a tensile test of ABS composites was conducted using a reciprocating tribometer and the results showed that the mechanical properties decrease with the increase of graphite particles amount.
TL;DR: In this article, an inclined columnar film microstructure was produced by the glancing angle deposition (GLAD) technique, which was used to deposit chromium thin films by dc magnetron sputtering.
Abstract: The glancing angle deposition (GLAD) technique was used to deposit chromium thin films by dc magnetron sputtering. With suitable operating conditions to favour a columnar microstructure and by controlling the orientation of the substrate relative to the impinging vapour flux, an inclined columnar film microstructure was produced. A systematic change of the angle ‘α’ between the incident atom flux and the substrate normal was correlated with the angle ‘β’ between the column's axis and the substrate normal. For every angular range (α increases from 0 to 50°), the results were corroborated with empirical relationships between angles α and β. The influence of the deposition at oblique incidence on the surface morphology and the microstructure was investigated by atomic force microscopy and by scanning electron microscopy. The evolution of the crystallographic structure was also examined by X-ray diffraction vs. the angle of the incident flux. Measurements of the conductivity and nano-indentation tests were also performed in order to discuss the change of the mechanical and electrical behaviours, as a function of the orientated microstructure of the coatings.
TL;DR: In this article, the influence of the shape of the pulsed rate on physical properties of these films was analyzed. And the colour variation of these titanium oxynitrides was investigated as a function of α in the L * a * b * colour space.
TL;DR: In this paper, the performance of a combined shunted periodic piezoelectric patch array with a cantilever beam was analyzed by investigating the velocity amplitude of the beam upstream and downstream of the array section and the number of control elements in the array.
Abstract: The use of both shunted piezoelectric elements and periodic arrays have been investigated independently as well as used in conjunction to modify the vibration of a system Piezoelectric patches bonded to a cantilever beam which is shunted with an active circuit, specifically a negative capacitance shunt, can control broadband flexural vibrations of a structure Also, periodic arrays integrated into a structure allow for modification of propagating waves through the mechanical ‘‘stop-bands’’ The performance of a combined shunted periodic piezoelectric patch array will be analyzed in this study by investigating the velocity amplitude of the beam upstream and downstream of the array section and the number of control elements in the array The negative capacitance shunts caused a global spatial average velocity reduction of 5 dB at the modal peaks from 500 to 5000 Hz The reduction is shown to be greater in the downstream section of the beam Also, by increasing the number of patches in the array, the attenu
