A Bayesian approach to model changes in volatility in the mexican stock exchange index
(Taylor & Francis, 2017)We model the changes in volatility in the Mexican Stock Exchange Index using a Bayesian approach. We study the time series with a wide set of models characterized by a Markov switching heterogeneity. The advantage of this ... -
A bayesian estimation of the economic effects of the common fisheries policy on the galician fleet : a dynamic stochastic general equilibrium approach
(Elsevier Ltd., 2019)What would have happened if a relatively looser fisheries policy had been implemented in the European Union (EU)? Using Bayesian methods a Dynamic Stochastic General Equilibrium (DSGE) model is estimated to assess the ... -
A comparative analysis of finite element programs for their implementation in a graphic tool of insulated power cables
(Institute of Electrical and Electronics Engineers Inc., 2018-05-11)In this article a summary is presented of the main commercial and non-commercial finite element analysis programs required for the electrical, thermal and magnetic study of isolated electric power cables, according to the ... -
A conceptual design of a firefighter drone
(Institute of Electrical and Electronics Engineers Inc., 2018)In this paper, a mechatronic design of a firefighter drone is presented. Unmanned aerial vehicles have been around for years, they present characteristics that aloud them to be used for different purposes. Nowadays, these ... -
A criticism of Edmund Burke's conception of patriotism
(2014)Este artículo se apoya en la literatura sobre el papel de las emociones en la filosofía de Edmund Burke para caracterizar su concepción del patriotismo, y para entender cómo se relaciona con otras dimensiones de su pensamiento ... -
A discrete bilevel brain storm algorithm for solving a sales territory design problem : a case study
(Springer Verlag, 2018)A sales territory design problem faced by a manufacturing company that supplies products to a group of customers located in a service region is addressed in this paper. The planning process of designing the territories has ... -
A fast and bio-inspired optical flow approach in cardiac MRI sequences
(Institute of Electrical and Electronics Engineers Inc., 2018)In this paper we present a fast and bio-inspired optical flow estimation method. It uses the Steered Hermite transform into an optimized Horn and Schunck approach. We tested the proposal method in cardiac MRI sequences of ... -
A genetic algorithm to solve power system expansion planning with renewable energy
(Springer Verlag, 2018)In this paper, a deterministic dynamic mixed-integer programming model for solving the generation and transmission expansion-planning problem is addressed. The proposed model integrates conventional generation with renewable ... -
A high step-up DC-DC converter with MPPT for PV application
(Institute of Electrical and Electronics Engineers Inc., 2018-01)This paper exhibits the performance of a high step-up converter employed for maximum power extraction in a photovoltaic system. The proposed converter is conformed by a conventional boost followed by a diode-capacitor-based ... -

A method for facial emotion recognition based on interest points
(Institute of Electrical and Electronics Engineers Inc., 2018)Current facial recognition techniques allow to automatically determine human emotions through a digital image of the face. The present study employs interest points as landmarks in facial images affected by some emotion ... -
A method for the outdoor thermal characterisation of high-concentrator photovoltaic modules alternative to the IEC 62670-3 standard
(Elsevier Ltd, 2018-02)The IEC 62670-3 standard recommends the open-circuit voltage method to calculate the cell temperature inside high-concentrator photovoltaic (HCPV) modules. This method requires knowledge of the temperature coefficient of ... -
A methodology for increasing revenue in fashion retail industry : a case study of a mexican company
(Emerald Group Publishing Ltd., 2018)Purpose: Fashion retail companies typically exhibit short life-cycles, high volatility and low predictability. Therefore, their success is largely determined by the organisation’s flexibility and responsiveness. The purpose ... -
A mixed integer formulation and an efficient metaheuristic procedure for the k-Travelling Repairmen Problem
(2016)In this paper, we study a k-Travelling Repairmen Problem where the objective is to minimize the sum of clients waiting time to receive service. This problem is relevant in applications that involve distribution of humanitarian ... -
A Monte Carlo simulator of non-WSSUS Rayleigh fading channels for vehicular communications
(Institute of Electrical and Electronics Engineers Inc., 2018)This paper presents a new simulator of non-wide-sense-stationary uncorrelated scattering (non-WSSUS) multipath Rayleigh fading channels for the performance analysis of vehicular communication systems. The proposed simulator ... -
A multi-objective probabilistic-based method to determine optimum allocation of time buffer in construction schedules
(Elsevier B.V., 2018-08)The use of buffers as a production strategy entails establishing a balance between theory and practice. In the complex environment of construction projects, this balance establishment requires an optimization process. It ... -
