The Soil Moisture and Ocean Salinity (SMOS) mission will provide L-Band multi-angular measurements of the surface emission with a 2-D interferometric radiometer on a global basis [1]. Soil moisture will be retrieved from collected and simulated data using a minimization algorithm. The success of the process will partly depend on how accurate is the modelling of the surface radiation and the cor...

Forest fires have environmental, social and economic impacts in many areas. Various factors related to territory directly influence both the number surface area of each fire. The link between different variables (climate, environmental) risk fire characteristics is studied here through Partial Least Squares - Path Models. In addition, images from Sentinel-2 sensor geographic information systems...

Toward minimizing bacterial colonization of surfaces, we present a one-step etching technique that renders aluminum alloys with micro- and nano-scale roughness. Such a multi-scale surface topography exhibited enhanced antibacterial effect against a wide range of pathogens. Multi-scale topography of commercially grade pure aluminum killed 97% of Escherichia coli and 28% of Staphylococcus aureus ...

Machined surface quality determines the reliability, wear resistance and service life of carbon fiber reinforced plastic (CFRP) workpieces. In this work, the formation mechanism of the surface topography and the machining defects of CFRPs are proposed, and the influence of milling parameters and fiber cutting angles on the surface quality of CFRPs is obtained, which can provide a reference for ...

This work investigates transport phenomena and mechanisms of droplet formation during a pulsed laser interaction with thin films. The surface of the target material is altered through material flow in the molten phase induced by a tightly focused laser energy flux. Such a process is useful for developing a laser-based micromachining technique. Experimental and numerical investigations of the la...

PURPOSE To examine the outcomes of photoastigmatic refractive keratectomy using corneal and refractive parameters for myopia and astigmatism in eyes with forme fruste and mild keratoconus. SETTING Private practice, Melbourne, Australia. METHODS Photoastigmatic refractive keratectomy was performed with a Star 1 or Star 2 laser (Visx) in 45 eyes with forme fruste or mild keratoconus using the...

1. QUANTIFYING SURFACE TOPOGRAPHY DIFFERENCES USING CCFmax AND Ds Topography measurements play an important role in surface and nano-metrology, production quality control, tribology, bio-technology and forensic science [1]. Dozens of surface parameters are specified in national and international standards [2, 3]. Although none of these are designed for topography comparisons, statistical method...
