Thomas Reid on the first principles of speculative, moral and political knowledge
(Universidade Federal de Minas GeraisUFMG, 2017-11-20)
This thesis aims to discuss Thomas Reids (1710-1796) theory of the first principles of knowledge, more particularly, the first principles of philosophy of mind, morals, and politics. In the first chapter, I discuss Reids ...
Global sensitivity analysis in the development of first principle-based eutrophication models
(Elsevier, 2010-12)
In this work, we formulate a dynamic first principle-based eutrophication model for a reservoir and perform global sensitivity analysis to determine most influential parameters. Both first-order and total sensitivity indices ...
Diffusion in thorium carbide: A first-principles study
(Elsevier Science, 2015-12)
The prediction of the behavior of Th compounds under irradiation is an important issue for the upcoming Generation-IV nuclear reactors. The study of self-diffusion and hetero-diffusion is a central key to fulfill this goal. ...
Vibrational effects on SrTiO3 Ti 1s absorption spectra studied using first-principles methods
(Iop Publishing, 2008-12)
We analyze the vibrational effects on the Ti 1s excited states in cubic SrTiO3 and related pre-edge x-ray absorption fine structure using first-principles methods. Ground-state, total-energy and electron-core hole ...
Three principles of competitive nonlinear pricing
(Fundação Getulio Vargas, 2002-03-01)
We make three contributions to the theory of contracting under asymmetric information. First, we establish a competitive analog to the revelation principIe which we call the implementation principIe. This principIe provides ...
Self-interstitials structure in the hcp metals: A further perspective from first-principles calculations
(Elsevier Science, 2016-12)
We study the structure of several standard and non-standard self-interstitial configurations in a series of hcp metals, by using Density Functional Theory as embodied in the computer codes SIESTA and WIEN2k. The considered ...
Environmental ethics: principles and values for a responsible citizenship in global society
(Centro Interdisciplinario de Estudios en Bioética de la Universidad de Chile, 2013)
Environmental ethics is an applied ethics which reflects about the grounds for duties and responsibilities of humans towards nature, living beings and future generations. The aim of this paper is to evaluate the planetary ...
