Structural stability, chemical order and reactivity pattern of MopWq clusters, with p + q = 8
(Springer, 2013-01)
The electronic structure and related properties of free-standing MopWq atomic clusters, with p + q = 8, are investigated within the framework of the fully unconstrained version of the density functional theory as implemented ...
Innovative design for optical porous silicon gas sensor
(Elsevier Science Sa, 2010-09)
A simple system for the detection of analytes in the atmosphere employing a freestanding nanostructured porous silicon optical microcavity was designed and built. The system is based on the measurement of optical transmittance ...
Numerical analysis of a finite element method to compute the vibration modes of a Reissner-Mindlin laminated plate
(American Mathematical Society, 2011-10)
This paper deals with the finite element approximation of the vibration modes of a laminated plate modeled by the Reissner-Mindlin equations; DL3 elements are used for the bending terms and standard piecewise linear ...
Understanding and manipulating diet choice in grazing animals
(Csiro Publishing, 2015-01)
Conventional models of foraging, such as optimal foraging theory, generally take the univariate approach to explain the decisions of consumers on the basis of the intrinsic properties of foods, including nutrient concentration ...
Selection of controlled variables: A novel perspective based on the singular energy of weighted graphs
(Elsevier, 2013-09-13)
The optimal selection of controlled variables is a well-known plant-wide control subproblem. In this paper, a novel approach based on spectral graph theory is proposed. This strategy is useful from both graphical and ...
Economic plant-wide control design with backoff estimations using internal model control
(Elsevier, 2016-04)
Economic optimal operation typically involves operating as close as possible to the active constraints. However, in the presence of disturbances it is necessary to back-off from the constraints in order to avoid violating ...
O plano multidimensional do acento na teoria da otimidade
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2004)
Este trabalho apresenta um modelo de análise métrica com base em restrições que opera com grades e constituintes organizados em um plano multidimensional governado por princípios que regulam as projeções na grade métrica. ...
The words we can all agree on: a computer-generated environment to test for evolution of lexical agreement
(Universidad de Chile, 2012)
This paper reports on an experiment in which virtual agents in a computer simulated program were set up to assimilate the evolution of lexical agreement based on Complex Adaptive Systems theory (Lee & Schumann 2003, Waldrop, ...
Self-consistent relativistic band structure of the CH3NH3PbI3 perovskite
(American Physical Society, 2014)
The electronic structure and properties of the orthorhombic phase of the CH3NH3PbI3 perovskite are computed
with density functional theory. The structure, optimized using a van der Waals functional, reproduces closely
the ...
Nested diets: a novel pattern of individual-level resource use
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Many generalist populations may actually be composed of relatively specialist individuals. This `individual specialization` may have important ecological and evolutionary implications. Although this phenomenon has been ...
