Optimized Compressed Sensing via Incoherent Frames Designed by Convex Optimization

The construction of highly incoherent frames, sequences of vectors placed on the unit hyper sphere of a finite dimensional Hilbert space with low correlation between them, has proven very difficult. Algorithms proposed in the past have focused in minimizing the absolute value off-diagonal entries of the Gram matrix of these structures. Recently, a method based on convex optimization that operat...

Hydrogen sensing by localized surface plasmon resonance in colloidal solutions of Au-WO3-Pd

Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...

Membrane - Based Solutions for Challenging Waters

The frontier of water treatment is being defined by hybrid approaches and thoughtful design integration. The use of increasingly sophisticated processes is driven by the need to treat dramatically impaired water supplies while maintaining low cost, high utilization, and high operational flexibility. Industrial wastewaters present an additional challenge, with increasing regulations and water sc...

Why Is Remote Sensing of Amazon Forest Greenness So Challenging?

The prevalence of clouds and aerosols and their impact on satellite-measured greenness levels of forests in southern and central Amazonia are explored in this article using 10 years of NASA Moderate Resolution Imaging Spectroradiometer (MODIS) greenness data: normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI). During the wet season (October–March), cloud contamina...
