To ensure the safety of buildings and structures, it is necessary to analyze structural integrity (robustness). The results various studies show that arches with radial ties make possible create an architecturally expressive, cost-effective material consumption solution problem girders bridging in public buildings, but robustness these systems poorly studied. This article presents failure analy...

This paper firstly studies the influence of variations in fuel tariffs and GHG emissions grid electricity on financial environmental metrics, demonstrating divergences when considered alone. Secondly, a combined economic objective function is proposed, yielding good compromise between both concerns. Real data are available from Brazilian Northeast building where electricity, heat (hot water), c...

Our research concerned the development of an autonomous robotic navigation system for orchard harvesting with a dual master-slave mode, tractor transport robot being master followed by picking as slave. This addresses problem that in single agricultural combined equipment cannot stop repeatedly between rows apple trees and drive continuously when turning. According to distances obtained from gl...

Intensive swine farming causes strong local environmental impacts by generating effluents rich in solids, organic matter, nitrogen, phosphorus, and pathogenic bacteria. Insufficient treatment of hog farm has been reported for common technologies, vermifiltration is considered a promising alternative that, however, requires additional processes to remove nitrate phosphorus. This work aimed study...
