Using MapReduce Streaming for Distributed Life Simulation on the Cloud
Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

Manipulador aéreo con brazos antropomórficos de articulaciones flexibles
[Resumen] Este artĂculo presenta el primer robot manipulador aĂ©reo con dos brazos antropomĂłrficos diseñado para aplicarse en tareas de inspecciĂłn y mantenimiento en entornos industriales de difĂcil acceso para operarios humanos. El robot consiste en una plataforma aĂ©rea multirrotor equipada con dos brazos antropomĂłrficos ultraligeros, asĂ como el sistema de control integrado de la plataforma y los brazos. Una de las principales caracterĂsticas del manipulador es la flexibilidad mecánica proporcionada en todas las articulaciones, lo que aumenta la seguridad en las interacciones fĂsicas con el entorno y la protecciĂłn del propio robot. Para ello se ha introducido un compacto y simple mecanismo de transmisiĂłn por muelle entre el eje del servo y el enlace de salida. La estructura en aluminio de los brazos ha sido cuidadosamente diseñada de forma que los actuadores estĂ©n aislados frente a cargas radiales y axiales que los puedan dañar. El manipulador desarrollado ha sido validado a travĂ©s de experimentos en base fija y en pruebas de vuelo en exteriores.Ministerio de EconomĂa y Competitividad; DPI2014-5983-C2-1-
