Degradable and Printed Microstrip Line for Chipless Temperature and Humidity Sensing

Danick Briand, James Alec Pierce Bourely, Jaemin Kim, Xavier Aeby, Oleksandr Vorobyov

Research on chipless and passive architectures for environmental sensing is generating high interest because they do not require any semiconductor components or batteries to operate, thus resulting in an eco-friendlier footprint. This study demonstrates a ...

Discomfort glare from daylight: Influence of transmitted color and the eye's macular pigment

Sneha Jain

Designing architectural façades that allow sufficient daylight to create visually comfortable and pleasantenvironments is a challenging aspect of building design. It requires accounting for visual comfort anddiscomfort glare risks and understanding the fac ...

Generation and control of localized terahertz fields in photoemitted electron plasmas

Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Ido Kaminer, Simone Gargiulo, Francesco Barantani

Dense micron-sized electron plasmas, such as those generated upon irradiation of nanostructured metallic surfaces by intense femtosecond laser pulses, constitute a rich playground to study light-matter interactions, many-body phenomena, and out-of-equilibr ...

Continuous Simulation Data Stream: A dynamical timescale-dependent output scheme for simulations

Loïc Hausammann, Matthieu Schaller

Exa-scale simulations are on the horizon but almost no new design for the output has been proposed in recent years. In simulations using individual time steps, the traditional snapshots are over resolving particles/cells with large time steps and are under ...

Comparison between CIE 2° and 10° field photopic luminosity functions V(λ) for calculating daylight discomfort glare metrics

Marilyne Andersen, Jan Wienold, Sneha Jain

The spectral sensitivity of the average human eye in photopic conditions is represented by the photopic luminosity function V (λ). The CIE has established the photopic luminosity functions for the 2o and 10o visual fields for a standard observer applicable ...

Validation of Spectral Simulation Tools for the Prediction of Indoor Daylight Exposure

Marilyne Andersen, Clotilde Marie A Pierson

A growing area of research focuses on the relationship between ocular light exposure and the non-visual responses. In order to accelerate research on this topic and improve building design, reliable spectral simulation tools are needed. This study aims at ...

An Introduction to Vein Presentation Attacks and Detection

Sébastien Marcel, André Anjos, Pedro Tomé

The domain of presentation attacks (PA), including vulnerability studies and detection (PAD) remains very much unexplored by available scientific literature in biometric vein recognition. Contrary to other modalities that use visual spectral sensors for ca ...

A fully organic retinal prosthesis restores vision in a rat model of degenerative blindness

Diego Ghezzi

The degeneration of photoreceptors in the retina is one of the major causes of adult blindness in humans. Unfortunately, no effective clinical treatments exist for the majority of retinal degenerative disorders. Here we report on the fabrication and functi ...

Light-driven model for identifying indicators of non-visual health potential in the built environment

María Lovísa Ámundadóttir

This thesis introduces a new approach to characterize and evaluate ocular light exposure based on the discovery of novel blue light-sensitive photoreceptors in the human eye. These photoreceptors are the primary mediators of 'non-visual' responses impactin ...
