Software as a Service (SaaS) is becoming a new direction of software industry in the new cloud computing era. In order to satisfy business policy changes and personalized requirements from different tenants in SaaS applications, business rule management must support multi-tenancy and online customization. This paper proposed a framework based on business rule engine, decoupling of business logic rule from SaaS application, which makes SaaS application more robust and maintainable. It takes business rule as an independent and online maintainable part of SaaS application, which could allow tenants to safely upgrade, delete or create rules during runtime. Finally, a practical case study of absence approval-process in attendance management system evaluates the effectiveness of the framework.

This paper presents a brain computer interface to control an intelligent wheelchair based on EEG signals. EEG signals are collected and analysed by using Emotiv. After signal processing, the events about motor imagery are generated and the commands are designed and transmitted to intelligent wheelchair. Finally, the system realizes the motion control of the intelligent wheelchair through subject's motor imagery of left hand, right hand and legs. Besides, the events about motor imagery are expressed in the form of virtual movement as the feedback of system. The Experiment results show that the control system is feasible and has better stability. It establishes a basis of practical application for EEG control intelligent wheelchair.
Human computer Interaction keeps moving toward interfaces which are more natural and intuitive to use, in comparison to traditional keyboard and mouse. Hand gestures are an important modality for human computer intera...

Automation of irrigation is an effective way to increase production. However, as an agricultural country, China is still in the initial stage of agriculture modernization. So it is significant to combine information technology with the agricultural irrigation and to develop an intelligent irrigation system which is suitable for the development situation of the agriculture. In the paper, an irrigation control system based on an FPGA is presented. Using RS-232 interface to communicate with a host computer, the system receives irrigation commands from the decision making system and controls automatically the irrigation of 16 greenhouses or pieces of field. A control panel is designed in the system to make it easier for users to manage and intervene the irrigating. There are 16 LEDs indicating the status of water shortage. A small keyboard is used for users to input commands and 12 Seven-segment displays are used for displaying the date and time or user inputs. With many I/O pins, flexibility, easy debugging and all the control logic supported, the control system based on an FPGA represents a new trend in hardware application design.

Enhancing the noise intensity is the rife method for compensating the errors of velocity caused by lever arm distortion. But the academic statistical characteristic of measurement noise is different from actual noise. So this paper proposes a new method to compensate errors of velocity. The new method is that static velocity errors caused by the lever arm distortion are compensated in the measurement equations and dynamic errors are added into the measurement noise. The statistical characteristic of new measurement noise is not constant and it changes in real-time. At the same time this paper proposes modified strong tracking filter, it is suitable for upon environment. The new algorithm can track and estimate the statistical characteristic of new measurement noise in real time. The results of simulation experiment show the modified strong tracking algorithm can improve the navigation precision, which is an effective and practical method.
