Extension of the B3LYP-dispersion-correcting potential approach to the accurate treatment of both inter-and intra-molecular interactions
(2013)We recently demonstrated that dispersion-correcting potentials (DCPs), which are atom-centered Gaussian-type functions that were developed for use with B3LYP (Torres and DiLabio in J Phys Chem Lett 3:1738-1744, 2012), ... -
Density-functional theory with dispersion-correcting potentials for methane: Bridging the efficiency and accuracy gap between high-level wave function and classical molecular mechanics methods
(2013)Large clusters of noncovalently bonded molecules can only be efficiently modeled by classical mechanics simulations. One prominent challenge associated with this approach is obtaining force-field parameters that accurately ... -
Leveraging speculative architectures for runtime program validation
(2013)Program execution can be tampered with by malicious attackers through exploiting software vulnerabilities. Changing the program behavior by compromising control data and decision data has become the most serious threat in ... -
Blind restoration of retinal images degraded by space-variant blur with adaptive blur estimation
(2013)Retinal images are often degraded with a blur that varies across the gield view. Because traditional deblurring algorithms assume the blur to be space-invariant they typically fail in the presence of space-variant blur. ... -
Development and/or change of the notion of permanent object and operative causality: Empirical evidence in the frst year of life
(Fundacion para el Avance de la Psicologia, 2013)This study examines the notion of permanent object during the first year of life, taking into account the controversy of two approaches about the nature of change: developmental change and cognitive change. Using a ... -
A multi-user remote academic laboratory system
(2013)This article describes the development, implementation and preliminary operation assessment of Multiuser Network Architecture to integrate a number of Remote Academic Laboratories for educational purposes on automatic ... -
Academic evaluation protocol for monitoring modalities of use at an Automatic Control Laboratory: Local vs. remote
(2013)This article describes an Academic Evaluation Protocol (AEP) designed and implemented in order to monitor various modalities of using an Automatic Control Laboratory by analyzing the quality of work that can be obtained ... -
Differential diagnosis of hemorrhagic fevers using ARTMAP and an Artificial Immune System
(2013)The differential diagnosis of endemic hemorrhagic fevers in tropical countries is by no means an easy task for medical practitioners. Several diseases often overlap with others in terms of signs and symptoms, thus making ... -
Quality differentiation with flavors: Demand estimation of unobserved attributes
(Walter de Gruyter GmbH, 2013)This article estimates the demand for mint-flavored gum products using grocery store sales data and accounting for consumers' valuation of quality. Unobserved product attributes, such as flavor quality, are important ... -
Energy consumption feedback devices' impact evaluation on domestic energy use
(Elsevier Ltd, 2013)Household energy accounts for one of the major contributors to the countries energy balances. It has been shown, that an effective way to achieve energy saving in that sector, is by providing consumers with information and ... -
Two-dimensional Einstein manifolds in geometrothermodynamics
(2013)We present a class of thermodynamic systems with constant thermodynamic curvature which, within the context of geometric approaches of thermodynamics, can be interpreted as constant thermodynamic interaction among their ... -
A static axisymmetric exact solution of f(R)-gravity
(2013)We present an exact, axially symmetric, static, vacuum solution for f(R)-gravity in Weyl's canonical coordinates. We obtain a general explicit expression for the dependence of df(R)/dR upon the r and z coordinates and then ... -
Pseudo asymptotic solutions of fractional order semilinear equations
(Cartagena de Indias, 2013)Using a generalization of the semigroup theory of linear operators, we prove existence and uniqueness of mild solutions for the semilinear fractional order differential equation [mathematical equation] with the property ... -
Form and void in Severo Sarduy's poetry
(Cartagena de Indias, 2013)In this essay we will elevate models on simulated models and/or figures in Severo Sarduy's poetry which can reveal the relationship between form and void and the philological and philosophical implications of that correlation. -
A three layer supply chain model with multiple suppliers, manufacturers and retailers for multiple items
(2014)The replenishment size/production lot size problem both for perfect and imperfect quality products studied in this paper is motivated by the optimal strategy in a three layer supply chain consisting of multiple suppliers, ... -
Restoration of retinal images with space-variant blur
(2014)Retinal images are essential clinical resources for the diagnosis of retinopathy and many other ocular diseases. Because of improper acquisition conditions or inherent optical aberrations in the eye, the images are often ... -
Programmable diffractive lens for ophthalmic application
(SPIE, 2014)Pixelated liquid crystal displays have been widely used as spatial light modulators to implement programmable diffractive optical elements, particularly diffractive lenses. Many different applications of such components ... -
Virtual lab in Modelica of a cement clinker cooler for operator training
(2014)Plant operator training plays a fundamental role in improving the energy efficiency of the cement manufacturing process and in reducing the CO2 emission. A virtual lab of a clinker grate cooler, intended for the training ... -
Hybrid choice model for alternative fuelled vehicles [Modelación híbrida para la elección de vehículos con energías alternativas]
(Interciencia Association, 2014)The promotion of alternative fuelled vehicles for the reduction of atmospheric emissions is a highly discussed topic nowadays. It requires evaluating the potential demand and people's preferences for vehicles using these ...
