2. Mathematical Analysis and Improvement of the Maximum Spatial Eigenfilter for Direction of Arrival Estimation
Abstract Maximum spatial eigenfiltering improves the accuracy of maximum likelihood direction-of-arrival estimators for closely-spaced signal sources but may interchangeably attenuate widely-spaced signal sources, producing a severe performance degradation. Although this behavior has been observed experimentally, it still lacks a mathematical explanation. In

3. Data processing within rows for sugarcane yield mapping
ABSTRACT: The mapping of sugarcane yield is still not as widely available as it is for grain crops. Sugarcane harvesters cut and process the cane in a single or maximum of two rows, facilitating the monitoring of cane yield and its behavior on a small scale. This study tested a method for sugarcane yield data cleaning, investigating if the data recording fre

4. Interplay between Near-Field Properties and Au Nanorod Cluster Structure: Extending Hot Spots for Surface-Enhanced Raman Scattering
Materials science has observed a continuous increase in the use of metal nanoparticles in a wide range of studies, from fundamental physics to technological applications such as photocatalysis and optical communication devices. This broad scope has the same fundamental origin, the localized surface plasmons, whose excitation leads to strong light confinement

5. Soil water content and net precipitation spatial variability in an Atlantic forest remnant
ABSTRACT. This study was carried out in an Atlantic forest remnant in Southeastern Brazil and aimed to spatially model the soil water content (SWC) and net precipitation (NP) on a monthly time scale and to assess the spatial behavior of these hydrological variables in the different seasons. NP is defined by summing throughfall and stemflow, which have been c

6. COMPARISON OF GNSS INDICES, IONOSONDES AND ALL-SKY IMAGERS IN MONITORING THE IONOSPHERE IN BRAZIL DURING QUIET AND DISTURBED DAYS
Abstract Measurements from the Global Navigation Satellite System (GNSS) have become a leading data source for ionospheric studies. Different technologies are used to monitor the ionospheric layer. It is possible to carry out this monitoring using GNSS networks through the indices of ionospheric irregularities, as well as through ionosondes and imagers. It h

7. Temporal stability of soil moisture in banana cropping area in the Brazilian semiarid region
RESUMO A umidade do solo é essencial para a produção agrícola. O conhecimento de sua variabilidade espaço-temporal é indispensável para suporte à agricultura, sendo fortemente influenciada pelas práticas culturais, condições de cobertura do solo e métodos de irrigação. Assim, este estudo teve como objetivo avaliar a estabilidade temporal e a di

8. Spatial and temporal distribution of South American fruit fly in vineyards
ABSTRACT The South American fruit fly Anastrepha fraterculus (Wied., 1830) is one of the major insect pests of economic importance in vineyards of Southern Brazil. Understanding species behavior and knowing the moments when their population peaks occur can help producers and technicians to define management strategies. This work was carried out the spatial a

9. Walking and walkability: do built environment measures correspond with pedestrian activity?
Resumo Desde o surgimento do termo “caminhabilidade”, na década de 1990, muitas métricas foram desenvolvidas com o intuito de avaliar a qualidade do ambiente construído sob a ótica do pedestre. Mais recentemente, alguns pesquisadores têm buscado uma associação dessas métricas com o comportamento dos pedestres: melhores condições das calçadas e

11. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously

12. Spatial distribution of dairy heifers’ dung in silvopastoral systems
RESUMO: Os ruminantes variam a trajetória de sua caminhada de acordo com o posicionamento das árvores em sistemas integrados. A deposição de fezes pode estar mais ou menos concentrada em determinados locais, de acordo com a disposição desses condicionadores de pastejo que definem o caminhamento animal. O objetivo deste experimento foi mapear a localiz
