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.

The fully implantable hearing devices (FIHDs) have been widely studied to solve the problems of conventional hearing aids. The microphone of FIHDs is implanted under the skin at temporal bone. So, it’s characteristics can be affected by bone-conducted noise, such as chattering teeth and eating food. In this paper, we investigated the effect of boneconducted noise on implanted microphone. To verify the noise effect, we implemented the physical model using the artificial bone and silicone. And a result, it confirmed that output signals are modified by bone-conducted signal.
