Microstructural characterization of as-cast hf-b alloys
(ABM, ABC, ABPol, 2012)
An accurate knowledge of several metal-boron phase diagrams is important to evaluation of higher order systems such as metal-silicon-boron ternaries. The refinement and reassessment of phase diagram data is a continuous ...
Columnar jointing in vapor-phase-altered, non-welded Cerro Galán Ignimbrite, Paycuqui, Argentina
(Springer Verlag Berlín, 2011-09)
Columnar jointing is thought to occur primarily in lavas and welded pyroclastic flow deposits. However, the non-welded Cerro Galán Ignimbrite at Paycuqui, Argentina, contains well-developed columnar joints that are instead ...
Second order SM regulator for nonlinear non minimum phase systems
(2011)
This paper explores how 30 years after their formation as squatter and irregular settlements self-built consolidated dwellings in Latin America are being passed from the original first generation low income home builders ...
Robust regulator for nonminimum phase systems by Lyapunov Redesign
(2012)
In this paper we present a robust sliding mode (SM) controller for nonlinear non minimum phase systems with unmatched perturbations. Based on Regulation and Lyapunov Redesign concepts we design a suitable sliding manifold. ...

Structural-functional approach to identify post-disturbance recovery indicators in forests from northwestern Patagonia: a tool to prevent state transitions
(Elsevier Science, 2015-05)
The disruption of the natural post-disturbance recovery process, either by changes in disturbance regime or by another disturbance, can trigger transitions to alternative degraded states. In a scenario of high disturbance ...
Estudo da formação de fase vítrea no sistema Fe-Mo-P-C-B utilizando cálculos termodinâmicos e critério de amorfização
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia de Materiais - EMa, 2022-09-15)
Glasses with high atomic concentration of iron have been studied due to its magnetic
properties, high mechanical and corrosion resistance, and low cost of the raw
material. However, these materials present low glass-forming ...
Nuevo método de identificación usando la respuesta escalón para sistemas de fase no mínima de segundo orden
(Universidad de Cuenca, 2014)
This paper presents a novel identification method for non-minimum phase systems based on the step response. The proposed approach provides a linear second-order model approximation avoiding complex experimental design. The ...
