Cloud-enabled webapp development service (cloud platform building guide)

- The objective is to build a cloud-enabled web application development service system
- The Platform includes five parts: Apache-tomcat-cluster, MySQL-LVS-cluster, Application interface, monitor system, and admin system
- More attention pays on the high-availability, balancing request
- The application interface is designed to improve the degree of automation, including code deployment, version control, and server scalability.
- Two kinds of eclipse plugin template are provided to help the programmers get the most convenience.

Intelligent Transport System

- Focused on simulation of the traffic condition on road as well as controlling the vehicles by traffic signal, aimed at relieving the pressure of heavy traffic.
- Simulate the Wuxi city’s traffic condition with more than 1400 nodes, more than 1800 road on the digital map.
- My main contribution was to add interface to simulate different region, variety of density, and also design 3 vehicle generating methods (random, time-based and region) as well as its path generating approaches (random, Dijkstra shortest and improved shortest).
