    Advances and trends of head-up and head-down display systems in automobiles
    (SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Externo - Escuela - Ingeniería
    Currently, in the automotive industry the interaction between drivers and Augmented Reality (AR) systems is a subject of analysis, especially the identification of advantages and risks that this kind of interaction represents. Consequently, this paper attempts to put in evidence the potential applications of Head-Up (Display (HUD) and Head-Down Display (HDD) systems in automotive vehicles, showing applications and trends under study. In general, automotive advances related to AR devices suggest the partial integration of the HUD and HDD in automobiles; however, the right way to do it is still a moot point. © 2014 SPIE.

    Current and future possibilities of V2V and I2V technologies: An analysis directed toward Augmented Reality systems
    (SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Arnedo, Aida; Yarce Botero, Andres; Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Arnedo, Aida; Yarce Botero, Andres; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
    Nowadays, it is very important to explore the qualitative characteristics of autonomous mobility systems in automobiles, especially disruptive technology like Vehicle to Vehicle (V2V) and Infrastructure to Vehicle (I2V), in order to comprehend how the next generation of automobiles will be developed. In this sense, this research covers a general review about active safety in automobiles where V2V and I2V systems have been implemented; identifying the more realistic possibilities related to V2V and I2V technology and analyzing the current applications, some systems in development process and some future conceptual proposals. Mainly, it is notorious the potential development of mixing V2V and I2V systems pointing to increase the driver's attention; therefore, a configuration between these two technologies and some augmented reality system for automobiles (Head-Up Display and Head-Down Display) is proposed. There is a huge potential of implementation for this kind of configuration once the normative and the roadmap for its development can be widely established. © 2014 SPIE.

    Functional analysis of fiber optic sensors using statistical photon counting: An automobile case study covered from quantum mechanics
    (SPIE-INT SOC OPTICAL ENGINEERING, 2012-01-01) Alejandro Betancur, J.; Alejandro Betancur, J.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
    Currently, the applications of fiber optic sensors on the automobile industry are gaining importance due to their potential for implementation in data acquisition and signal transmission. This paper covers from quantum mechanics, the photon counting in optical fibers using coherent states and generalized intelligent states, described by hyper-geometric functions and Bessel functions. Different fiber optic configurations will be showed, in order to show some representative factors that influence the probability of coherent and intelligent photons detected and transmitted by optical fibers. Finally, from the automotive industry, some applications are presented, from which the quantum-optical approach here proposed makes sense. © 2012 SPIE.

    Head-up and head-down displays integration in automobiles
    (SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Externo - Escuela - Ingeniería; Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Externo - Escuela - Ingeniería; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
    In automotive industry, the dashboard has been ergonomically developed in order to keep the driver focused on the horizon while driving, but the possibility to access external electronic devices constraints the driver to turn away his face, generating dangerous situations in spite of the short periods of time. Therefore, this work explores the integration of Head-Up Displays and Head-Down Displays in automobiles, proposing configurations that give to drivers the facility to driving focused. In this way, some of the main ergonomic comments about those configurations are proposed; and also, some technical comments regarding the implemented arrangements are given. © 2014 SPIE.

    Solving the assignment of customers to trucks and visit days in a periodic routing real-world case1
    (Pontificia Universidad Javeriana, 2018-01-01) Duque Correa A.F.; Baldoquín de la Peña M.G.; Duque Correa A.F.; Baldoquín de la Peña M.G.; Universidad EAFIT. Departamento de Ciencias; Matemáticas y Aplicaciones
    Introduction: This work proposes a model and two heuristic algorithms to assign customers to trucks and visit days as a first phase in the solution of a real-world routing problem, which is closely related to the PVRP (Periodic Vehicle Routing Problem), but a strategic decision of the company imposes the additional constraint that every customer must always be visited by the same truck. Methods: The proposed model will group the customers that are visited the same day by the same truck as close as possible by means of centroid-based clustering. The first proposed heuristic has a constructive stage and three underlying improvement heuristics, while the second uses an exact linear programming algorithm. Results: The algorithms are evaluated by instances taken from the literature and generated, taking into account the characteristics presented in the real-world case. © 2018, Pontificia Universidad Javeriana.
