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 ... -
A new framework for cognitive mobility of visually impaired users in using tactile device
(Institute of Electrical and Electronics Engineers Inc., 2017)This paper proposes a novel framework for a better understanding of human cognitive locomotion and its interaction with the new tactile technologies that assist mobility and the acquisition of spatial knowledge in the ... -
A new hybridized algorithm based on population-based simulated annealing with an experimental study of phase transition in 3-SAT
(Elsevier B.V., 2017)This paper is about experiments for satisfiability problem using a new algorithm (GR-MM-PBSA) that improves the algorithm Population-Based Simulated Annealing (PBSA). GR-MM-PBSA runs in a parallel way Simulated Annealing ... -
A new method to optimize BGP routes using SDN and reducing latency
(Elsevier B.V., 2018)Latency on Internet mainly depends on the distance that packets travel in WAN networks1. This latency can be reduced if the hops between autonomous systems are reduced. This is the main function of the BGP protocol that ... -
A new swarm algorithm for global optimization of multimodal functions over multi-threading architecture hybridized with simulating annealing
(Elsevier B.V., 2018)This paper presents a new algorithm, PCLPSO, based on particle swarm optimization, which uses comprehensive learning particle swarm optimizer. Our algorithm executes C parallel CLPSO algorithms. We adopted as a criterion ... -
