With the development of VLSI and intelligent technology, the design idea and implementation scheme for real-time new nuclear information processing system are proposed. Based on ARM+WinCE+UART, the portable energy-spectral measurement system can analysis the nuclear signal characteristics from different detectors, to determine the physical nature of radiation. The development of software modules under Windows CE are elaborated in detail, including the serial port driver, UART interrupt handling and flow control, custom communication protocols etc. It describes the application to communicate with hardware implementations through software interface design. The test result shows that the system can not only complete the analysis of the signal amplitude but also achieve other functions such as the time-characteristics of nuclear signal, waveform recognition, signal sorting selection etc.

Nowadays more fuzz testing research mainly focuses on some certain phase and on some certain protocol, there is not an research on integrated system realization has been emerged. This paper presents the idea of an automated fuzz testing method for all protocols. First it adopted Finite State Machine (FSM) model in fuzz testing, and after a FSM constructed an efficient algorithm is presented for state space reduction. Last it selected every sequence for the mutation test. In this method, the FSM is created by program other than manual work that make the fuzz testing automated and suit for all protocols.

We propose a pricing model for convertible bonds with Monte Carlo simulation. Our method focuses on a parametric representation of voluntary conversion decisions, which constitute the optimal exercise decision together with the call decision based on the predetermined trigger price. Furthermore, our model can be easily extended to some complex conditions where credit risk, stochastic volatility, and term structure of interest rate are considered, under which it still remains intuitive and efficient.

Cooperative networking is a highly promising communications paradigm that is expected to play an essential role in the next generation of wireless mobile networks. Many cooperation opportunities are found and decisions are made at MAC layer, where a performance index is needed as a reference to evaluate the effectiveness of cooperations. In this work, we serve this purpose by proposing a saturation throughput gain (STG) index. We present mathematically the STG of the MAC layer cooperative data relaying of direct spread spectrum ultra wide band systems. The result shows that STG can effectively evaluate the cooperation gain at MAC layer and varies significantly with different MAC layer fairness mechanisms.

The integration of Service-Oriented Architecture (SOA) and Event-driven architecture (EDA) make it possible to build a seamlessly modern business system based on discrete units. However, the interface between them is not clearly defined. This paper focuses on the Rapid Prototype (RP) industry, and aims to realize a real-time RP monitoring system, which is able to monitor RP services and control RP processing flow. A RP oriented ED-SOA framework is provided. Based on the publish/subscribe mechanism, the devices can be controlled by the events. A prototype system is developed to demonstrate how exception message is generated and transferred from the service layer to the application layer.

Understanding the human behaviors in driving is a highly complex topic but on the other hand, extremely important for improving human's driving competence by developing driver assistant systems accordingly and finally accomplishing fully autonomous vehicles and road systems. There are many excellent researches in this area for decades. However, by building a comprehensive system to evaluate human driver's behavior, we found that none of the existing model can reflect the same outcome as our observation from the real world in the multiplex traffic scenario. But this is indeed important for us to find the right way to improve road traffic efficiency as well as develop autonomous vehicles. In this work, we combined couple of previous approaches to a single model with some improvements and successfully implemented it into a new simulator which can be used to evaluate other traffic applications upon the driver behavior model. We focused on lane changing decision of the driver behavior since it is the most complex part and causes the most problem and inconsistency in previous researches. After comparing the result getting from the simulation based on the new model with the real world observation, we can conclude that the new driver behavior model does reflect the real world scenario. And the model and simulator also helps us in our further researches in intelligent traffic control area.

Feature extraction is an indispensable preprocessing step for the large data, high redundancy hyperspectral remote sensing image (HSI). In this paper, a manifold inspired method, e.g., Laplacian Eigenmap (LE) is introduced for hyperspectral image dimensional reduction. In order to overcome the shortcoming of conventional manifold learning which could not deal with large data, linearization procedure for LE is proposed based on multiple linear regression analysis. Experiment on hyperspectral dataset demonstrates that the proposed manifold inspired feature extraction (MIFE) could preserve the local geometry of the samples in the original feature space. The low dimensional feature image could achieve a better classification accuracy rate.

With the dramatic increase of the amount of network information, the phenomenon of merchandise information overload has become more and more serious. Thus, the e-commerce sites are required to provide the most needed information for customers to attract their attention. The traditional recommendation algorithm ignores the connections among user's own attributes and the changes in project scoring with each passing day. With the research of the traditional collaborative filtering recommendation algorithm, the paper put an emphasis on the combination of user model and user project matrix, and introduced the data of user attributes and the variation values of project scoring over time into the traditional recommendation algorithm. By experiment, the validity of the algorithm was confirmed.

Face to massive web log data, single log analysis has been unable to meet people's pursuit of high efficiency, the traditional log analysis based on Hadoop has some drawbacks in resource utilization, etc. Therefore, based on traditional Hadoop task scheduler, a new tasks pre-scheduling mechanism based on node-ability is proposed, the size of the task block is determined according to the ability of each processing node. Thus, the conflicts between job execution time and system resource utilization is balanced, which can protect the jobs of the response time and effective enforcement mechanism to reduce the weight of the additional overhead and improve overall resource utilization.
