People exposed to traffic noise in european agglomerations from noise maps: a critical review
Two of the main objectives of the European Directive on environmental noise are, firstly, to unify acoustic indices for assessing environmental noise and, secondly, to standardize assessment methodologies. The ultimate ... -
Simple fabrication of ultrahigh aspect ratio nanostructures for enhanced antireflectivity
In this work, the authors present a novel fabrication process to create periodic nanostructures with aspect ratio as high as 9.6. These nanostructures reduce spectral reflectance of silicon to less than 4% over the broad ... -
Strategic noise map of a major road carried out with two environmental prediction software packages
The main objective of this study is to analyze the differences found in the results of noise mapping using two of the most popular software techniques for the prediction of environmental noise. The location selected ... -
Strong angular dependence of resonant states in 2D dielectric cylinder rings
We investigate collective resonators made of dielectric cylinders assembled as two-dimensional regular octagons and decagons. These structures exhibit collective resonance states that change their intensity with the incident ... -
Structurally oriented nano-sheets in Co thin films: changing their anisotropic physical properties by thermally-induced relaxation
We show how nanocrystalline Co films formed by separated oblique nano-sheets display anisotropy in their resistivity, magnetization process, surface nano-morphology and optical transmission. After performing a heat treatment ... -
Study of optical fiber sensors for cryogenic temperature measurements
In this work, the performance of five different fiber optic sensors at cryogenic temperatures has been analyzed. A photonic crystal fiber Fabry-Pérot interferometer, two Sagnac interferometers, a commercial fiber Bragg ... -
Study of the martensitic transition in Ni-Mn-Sn-Ti ferromagnetic shape memory alloys
In the present work, mechanical spectroscopy measurements as a function of temperature and strain have been performed in (at.%) Ni50Mn37Sn13-xTix (x=0, 0.5 and 2) ferromagnetic shape memory alloys in order both to study ... -
Theoretical modeling and experimental verification of the scattering from a ferromagnetic microwire
This contribution presents a theoretical modelling of the scattering of ferromagnetic microwires in free-space and inside a rectangular waveguide, providing both an analytical solution and a physical interpretation of ... -
Thermal degradation of type I collagen from bones
The denaturation processes of collagen in the temperature range between 450 K and 670 K are revealed through studies performed on cow rib bones by means of mechanical spectroscopy, differential scanning calorimetry, ... -
Uncertainties caused by source directivity in room-acoustic investigations
Although deviations in the measurement of acoustic parameters should be lower than the subjectively perceivable change in the corresponding parameter measured, this study reflects that directionality of sound sources could ...
