1. The skin through reflectance confocal microscopy -Historical background, technical principles, and its correlation with histopathology
Abstract Since its first introduction into medical practice, reflectance confocal microscopy (RCM) has been a valuable non-invasive diagnostic tool for the assessment of benign and malignant neoplasms of the skin. It has also been used as an adjunct for diagnosing equivocal cutaneous neoplasms that lack characteristic clinical or dermoscopic features. The us

2. COMPARING A SINGLE-SENSOR CAMERA WITH A MULTISENSOR CAMERA FOR MONITORING COFFEE CROP USING UNMANNED AERIAL VEHICLES
ABSTRACT There exist two options for digital cameras that can capture the near-infrared (NIR) band. Conventional red–green–blue (RGB, visible bands) cameras with a single sensor provide NIR band visibility based on the removal of the internal NIR-blocking filter. Alternatively, multisensor cameras exist that have a specific sensor for each band. The modi

3. El análisis de imágenes como herramienta de monitoreo en la deshidratación de rodajas de banana
Abstract The objective of this work was to evaluate the morphometric, fractal and color changes during the dehydration of banana slices through the use of image analysis. The convective drying was performed between 75 °C and 134 °C at an air velocity of 0.65 m s-1. Results showed that the images provided quantitative information of the morphometric changes

4. Potential of Texture Analysis for Charcoal Classification
Abstract Charcoal produced from reforested wood can be distinguished from the charcoal derived from the wood of native species. This identification is very important for the trade, control and monitoring of charcoal production in Brazil. This study investigated the potential of texture analysis for classifying the charcoal based on origin (eucalyptus or nati

5. Monitoring of Sobradinho landslide (Brasília, Brazil) and a prototype vertical slope by time-lapse interferometry
Abstract The application of geophysical monitoring technologies may offer an opportunity to understand the dynamic of slopes in response to factors triggering their instability. In this study, Ambient Noise Interferometry was used as a monitoring approach on a man-made reduced-scale vertical slope and on a natural-scale landslide in Sobradinho (Brazil), unde

7. DISPLACEMENT MEASUREMENT IN SAWN WOOD AND WOOD PANEL BEAMS USING PARTICLE IMAGE VELOCIMETRY
ABSTRACT Throughout their useful life structures demand monitoring to verify their conditions of use. Thus, the need arises to seek methodologies capable to evaluate displacements and deformations in structural components of buildings. The objective of this research was to evaluate the use of the particle image velocimetry (PIV) technique to analyze test spe

10. Cytotoxicity Assessment of a Poly(methyl methacrylate) Synthesized for the Direct Fabrication of Bone Tissues
ABSTRACT A cytotoxicity study is performed on a poly(methyl methacrylate) polymer (PMMA) to be used for the fabrication of bone tissue by Rapid Prototyping (RP). The solution polymerization is conducted in a pilot plant reactor using more appropriated reagents in consideration of the medical application. Moreover, the polymer is efficiently handled to avoid

11. Thermographic Images to Measure Health Risks of Workers Exposed to Artificially Refrigerated Environments
ABSTRACT Thermography generates high-resolution imagery in real time and is a non-invasive and painless technique devoid of physical contact or exposure to any type of radiation. This technique has been successfully applied to different areas, such as health- and safety-related applications, to control cold risk in workers exposed to low-temperature environm

12. Two approaches to calculate TVDI in humid subtropical climate of southern Brazil
ABSTRACT: Soybean crops occupy most areas in Rio Grande do Sul State and are highly dependent on rainfall since most of them are non-irrigated. Rainfall during the harvest period is often insufficient to meet the water demand, making water indicators an important tool for the crops. This study compared two approaches in the parameterization process of TVDI (
