Examination of commercial ceramic coatings for the electrical insulation of Bi-2212 wire

Andrea Testino, Davide Uglietti, Robert Sobota

In the last twenty years, a number of studies have been dedicated to the development of thin ceramic coating for the electrical insulation of Ag-sheathed Bi-2212 wires. Instead of preparing a coating by mixing different compounds in house, this technical n ...

Last Heir or First Engineer? An Intellectual Portrait of Vincenzio Viviani through his Working Papers

Simon François Dumas Primbault

Self-proclaimed Galileo’s ultimo discepolo, Vincenzio Viviani (1622-1703) strove all his life to become a renowned mathematician. Extolling the supposed purity of Euclid’s geometry, he sought to recover the lost knowledge of the Ancients, and fashioned him ...

Hydrodynamic mechanisms of aggressive collapse events in leading edge cavitation

Mohamed Farhat, Ali Amini

Transient cavities generated from unsteady leading-edge cavitation may undergo aggressive collapses which are responsible for cavitation erosion. In this paper, we studied the hydrodynamic mechanisms of these events in the leading edge cavitation formed ov ...

Angular Color Prediction Model for Anisotropic Halftone Prints on a Metallic Substrate

Roger Hersch, Lin Yang, Petar Pjanic

Under specular reflection, non-isotropic halftones such as line halftones printed on an ink-receiving plastic layer superposed with a metallic layer change their colors upon in-plane rotation of the print. This color change is due to the orientation-depend ...

Temperature sensitivity enhancement in a standard optical fiber with double coatings at low temperature

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

The thermomechanical behavior of a standard optical fiber with double coating is theoretically analyzed at room temperature and ~ 220 K. As the primary coating becomes stiffer at low temperature, the impact of the thermal expansion of the coatings is no lo ...

Sampling at unknown locations, with an application in surface retrieval

Martin Vetterli, Adam James Scholefield, Benjamin Bejar Haro, Michalina Wanda Pacholska

We consider the problem of sampling at unknown locations. We prove that, in this setting, if we take arbitrarily many samples of a polynomial or real bandlimited signal, it is possible to find another function in the same class, arbitrarily far away from t ...

Analyzing halftone dot blurring by extended spectral prediction models

Roger Hersch, Mathieu Hébert

Spectral prediction models for halftone prints generally assume homogeneously thick and sharply edged ink dots, i.e., bilevel halftones. In real prints, the ink thickness often decreases at the boundaries of the ink dots, thereby forming continuous-level h ...
