MapReduce is popular in cloud computing area. It’s mainly used in Information Retrieval, Distributed Storage, DM, Machine Learning and so on. It’s fit to parallel computing of great capacity for liquor data. Based on MapReduce’s property, we designed a computing model for option pricing with BSDEs on it. Option pricing is one of the most important parts in financial area. To promote precision of pricing, option pricing need complex calculating with big data set. This paper shows the implementation of option pricing with BSDEs on MapReduce. It gives the detail mapper and reducer method, and displays the architecture of the model of option pricing on MapReduce. In theory, the paper analyzes its feasibility and proves that MapReduce can get great performance and nicer speedup. It can be extended in financial area.

In order to satisfy the robot assisted surgery requirment to automatic identify the object in high precision. Regard the ellipse and the circle as a template. The ellipse and the circle are all contained the black block and the white block interactively. The corners in the image are detected by the Shi and Tomasi’ algorithm. After the image enhanced for improving the contrast of the image, using the symmetric properties of the black block and white block in the templates, the corners in the templates are found. Then the corners in the ellipse and in the circle will be extracted. At last using verctor vertical relationship, the target corners in the ellipse will be found. That is, the template will be detected. Finally, the experiments show that positioning error of the corner are less than one pixel, which satisfy the requirement of the surgery.
One of the most critical issues in the wireless sensor networks is the network's nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency. Clustering is a method to make...
