1. Join in the development of a software for intelligent public transportation system. The software is written using C# programming language and is developed for bus dispatchers. It consists three parts including algorithm service, application service and user interface. The first two parts is background services and the last part is designed for clients. I took part in the development of UI design, DB query and display, communication data processing and interactive operations.2. Finish the automatic scheduling algorithm for buses and help to launch on the market. The algorithm is to offer a reasonable schedule of bus departure time taking some abnormal cases into condition. Abnormal cases includes late arrival of drivers or buses, traffic jam, buses breakdown, etc. It frees bus dispatchers from adjusting schedule all the time. It is used by 2 routes in the city ChengDu for test and shows good performance.3. Join in the distribution of the prediction model for bus delays and traffic jam based on big data and invoke the corresponding interface methods.4. Finish the automatic algorithm for counting bus shifts with GPS.

1. Study background knowledge about Magnetic Calibration in SensorHub. Magnetometer is an important part of an electronic compass, which is used for navigation. But it can generate errors caused by local magnetic field, temperature, etc. I studied those backgrounds and the importance of magnetic calibration.2. Learn the principle of magnetometer and finish the calibration algorithm based on ellipsoid fitting. Ideally, the vectors of magnetic field strength collected by 360 degree rotation of an magnetometer form the surface of an spherical. With the influence of errors, the surface is ellipsoid. I calculated the error variables in the ellipsoid function and finished the calibration.

1. Design GPU parallel computing algorithm for LDPC decoding to speed up 50 times. Low density parity check code is widely used in communication. It consists of information bits and check bits. Given the decoding matlab codes, my job is to write GPU parallel computing algorithm for acceleration.2. Study OpenCL and CM languages. Learn host and kernel coding methods and write GPU parallel algorithm based on OpenCL and CM.
