Limitations current COTS radar systems are also discussed further research directions proposed towards development taking account different...
O uso inadequado de antibióticos na população pediátrica tem sido um problema recorrente, impulsionado pela prescrição excessiva para infecções virais e falta critérios diagnósticos bem definidos em alguns contextos clínicos. A exposição precoce desnecessária a esses fármacos pode comprometer o equilíbrio da microbiota intestinal, predispondo alterações imunológicas metabólicas, além contribuir crescente resistência bacteriana, fenômeno que compromete eficácia terapêutica dos...
The deep ocean is vast and challenging to observe; however, it key knowledge of the sea its impact on global climate. Fixed observing points (such as EMSO nodes) provide a limited view are complemented by expensive oceanographic campaigns with systems demanding high logistical requirements such deep-sea ROVs. These costs not only limit our capability for data collection in but also introduce their own environmental costs.Emerging challenges pressure exploration demand new technological...

Abstract. A unique dataset of marine atmospheric electric field observations over the Atlantic Ocean is described. The data are relevant not only for electricity studies, but more generally studies Earth's atmosphere and climate variability, as well space–Earth interaction studies. In addition to data, includes simultaneous measurements other variables, including gamma radiation, visibility, solar radiation. These ancillary support interpretation understanding also interest in themselves....

Information from low cost embedded robotics vision (LSAVision),...
The Fortaleza de Minas Ni–Cu–PGE sulfide deposit is hosted by Archean komatiitic rocks of the Morro do Ferro greenstone belt, near southwestern margin Sao Francisco craton, Gerais state, Brazil. contains 6 million tonnes ore with an average grade 2.2 wt% Ni, 0.4% Cu, 0.05% Co and 1.2 ppm PGE+Au, comprises (i) a main orebody, which metamorphosed, deformed transposed along regional shear zone, consisting mainly disseminated, brecciated stringer ores that are interpreted to be early magmatic...
Emerging opportunities in the exploration of inland water bodies, such as underwater mining flooded open pit mines, require accurate real-time positioning multiple assets. In operation scenarios, operational requirements deny application standard acoustic techniques, posing additional challenges to localization problem. This paper presents a novel solution, implemented for ¡VAMOS! project, based on combination raw measurements from short baseline (SBL) array and an inverted ultrashort...
This study was undertaken to characterize the mineral paragenesis and metal zoning at property scale, evaluate potential sources of ore-related metals, quantify relationship between intensity alteration gold grade, propose a comprehensive genetic model for Carlin-type Au deposits southern part Goldstrike property, Nevada. Mineralogy, textural relationships, whole-rock composition, spatial distribution studied samples revealed two types ore: Ore I II. The former, which is hosted by Roberts...

Recommender systems are able to suggest the most suitable items a given user, taking into account user’s and item`s data. Currently, these offered almost everywhere in online world, such as e-commerce websites, newsletters, or video platforms. To improve recommendations, context should be considered provide more accurate algorithms achieve higher payoffs. In this paper, we propose pre-filtering recommendation system that considers of coworking building suggests best workplaces user. A...
Contemporary error research suggests that the quest to eradicate is misguided. Error commission, detection, and recovery are an integral part of cognitive work, even at expert level. In collaborative workspaces, perception potential directly observable: workers discuss respond perceived violations accepted practice norms. As captured corrected preemptively, they do not fit Reason's widely definition as "failure achieve intended outcome." However, suggest aversion error, consequently have...
