    Pytos: A Framework for Mobile Computation Offloading in Python
    (Institute of Electrical and Electronics Engineers Inc., 2016) Soto Mendoza, Enrique Arturo; da Conceicao, Arlindo; Mamani Aliaga, Alvaro; Vieira, Dario
    Cloud-based offloading may improve mobile application performance and reduce energy consumption by migrating mobile code execution to the cloud. Nevertheless, it is not always the best bet, because of the high WAN delay. This article presents Pytos, a framework for Python, that allows code migration to the network edge (cloudlet), mitigating latency limitations. Pytos provides a transparent offloading mechanism to end users, hence the system discovers available cloudlets in the network automatically. To developers, Pytos provides a simple programming model at method-level granularity. Empirical evaluation showed that Pytos may improve performance and energy consumption up to 20 times. © 2015 IEEE.

    Tunki project: Wetland remote sensing using satellite images and high performance computing
    (Latin American and Caribbean Consortium of Engineering Institutions, 2018) Mamani Aliaga, Alvaro; Yari Ramos, Yessenia Deysi; Apaza Veliz, Ronald; Aco Cardenas , Pablo Yanyachi
    Wetlands are important for the world due to the benefits they offer to humanity. However, there are studies showing their decrease in number in several regions. A form of monitoring of the wetlands is necessary to evaluate their reduction, appearance and / or disappearance. The Tunki project is a project to detect wetlands in a given region using satellite images and high-performance computing. The present work, exposes its architecture and its case study: the wetlands in the Chili river basin of the Arequipa-Peru region. The results show the wetlands detected and the mosaics generated using the satellite images and HPC. © 2018 Latin American and Caribbean Consortium of Engineering Institutions. All rights reserved.
