A Mobile Game to Collect and Improve Position of Images

Photocaching, an online mobile game, is a system to collect and improve position of images at the same time. It is based on the human computation concept which means everyone involved is contributing, improving and deciding the results. We developed a system to rate the descriptiveness of images as well as some methods to improve position. Analysis on data collected from the game so far verified the system and methods.

System and interfaces for water quality monitoring and control in aquaculture

In this paper, we describe an environment monitoring and control system for fish farming applications. This system can receive sensor data in proprietary format and map it to a standard data model. All sensor data and control commands can be accessed via well defined HTTP RESTful interfaces. With this interface, historical data and statistics can be easily accessed and application development time can be greatly shortened.
