The strength of annealed, heat-strengthened and fully tempered float glass

In the last two decades architectural glass has made an enormous leap from a secondary material to a material that combines structural and cladding roles. The structural role is a new and problematic one. In contrast to most other engineering materials the ...

A subjective study of the influence of color information on visual quality assessment of high resolution pictures

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux

This paper presents the design and the results of a psychovisual experiment which aims at understanding how the color information affects the perceived quality of a high resolution still picture. The results of this experiment help to shed light into the i ...

MICROCRYSTALLINE SILICON SOLAR CELLS: EFFECT OF SUBSTRATE TEMPERATURE ON CRACKS

Christophe Ballif, Martin Python

Single junction microcrystalline silicon solar cells presently reach confirmed efficiencies up to 10.1%. Further improvement on device quality is now necessary to continuously increase the electrical performances of the solar cells. Zones of porous materia ...

Contaminazioni linguistiche

Paola Tosolini

In contemporary debates about sustainable development, vernacular architecture plays an important role. Presenting itself as a dictionary of man’s constructive logic, it declares with no uncertainty its own usefulness, its connection to the soil, to the cl ...

MDCT for Encoding Residual Signals in Frequency Domain Linear Prediction

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Frequency domain linear prediction (FDLP) uses autoregressive models to represent Hilbert envelopes of relatively long segments of speech/audio signals. Although the basic FDLP audio codec achieves good quality of the reconstructed signal at high bit-rates ...

Single-photon and photon-number-resolving detectors based on superconducting nanowires

Francesco Marsili

Nanowire superconducting single photon detectors (SSPDs) [1] are characterized by very high sensitivity in the near infrared (detection efficiency η up to 30%, for a dark count rate DK of few Hz), speed (up to ∼1 GHz repetition rate) and time resolution (j ...

Joint registration and super-resolution with omnidirectional images

Pascal Frossard, Zafer Arican

This paper addresses the reconstruction of high resolution omnidirectional images from multiple low resolution images with inexact registration. When omnidirectional images from low resolution vision sensors can be uniquely mapped on the 2-sphere, such a r ...
