Research Assistant

China University of Geosciences

  • Reviewed related literatures (mainly in Cloud Computing)
  • Constructed the cloud computing platform for our faculty:

    • Designed the virtualization solution for the cluster. (based on Xen)
    • Deployed Hadoop and related application(Hive, Spark, Solr …) on the cluster.
    • Supported the experiment of Deep Learning in our lab.
  • Studied MapReduce programming model and did research on it:

    • Read the source code of MapReduce in Hadoop project.
    • Proposed a new method to reuse the intermediate results automatically and data-awarenessly and implemented the prototype system by modifying the core code of MapReduce.
    • Evaluated the performance on the cluster and got the result that the system could improve the performance up to 24.6% compared with the previous optimization work.
    • The paper is published on CCPE. (Title: MEMoMR: Accelerate MapReduce via reuse of intermediate results)
  • Managed the cluster in our faculty:

July 2009 – August 2012
Wuhan, Hubei, China

Undergraduate Research Assistant

China University of Geosciences

  • Reviewed related literatures (mainly in Computer Vision and Robotics).
  • Participated in The 9 th Robot Soccer Tournament of China and The Tryouts for FIRA in Changchun in freshmen year.
  • Studied the architecture and implementation of ROS(The Robot Operating System) and preliminarily deployed it on the robots control panel (Version: RB100 by RoBoard).
  • Successfully applied for The National College Students Innovation Experiment Program (with funding):

    • Topic: Small Model Aircraft Autopilot System and Aerial Photo Research
    • Chose Quadrotor(an aircraft with four rotors) as the carrier platform of the research.
    • Studied the theory of balancing the Quadrotor with MikroKopter(one of the most famous open source UAV projects).
    • Studied and implemented the point clouds registration algorithm ICP and RANSAC on ROS.
    • Used ASUS Xtion PRO (a device like Kinect) to get the point cloud data and evaluated the algorithm.
    • Wrote graduation thesis based on this topic.(Title: the Design and Implementation of the Quadrotor Autopilot and 3-D Point Cloud Generation and Processing System)
