Abstract: In this paper, A new algorithm for compressed image retrieval is proposed based on Gaussian Density Feature Vector(GDFV). This algorithm directly extract gaussian density of 8 direction from compressed image data to construct a 2-dimention array (8*4) as an indexing key to retrieve images based on their content features. To test and evaluate the proposed algorithms, we carried out experiments with a database of 1000 images. In comparison with existing representative techniques, the experimental results show the superiority of the proposed method in terms of retrieval precision and processing speed.

Abstract: We take advantage of the non-performing loan ratio as the main indicators of credit risk of the commercial bank, make use of the experience of domestic and foreign research, use LOGIT methodology to construct the stress testing model for the macro-economic factors’ impact of China on credit risk of commercial bank, and apply the hypothetical scenario to the test of macro stress in order to make an assessment in quantity for the impact of the macro-economic changes on the credit risk of the commercial bank system. The results show that the stress tests and applied technology can make a contribution to useful reference of credit risk management of the commercial bank of China.

Abstract: After years of efforts and exploration of medical personnel, our physical examination work of school infirmaries has gradually embarked on a scientific and standardized track. But there are still a series of problems, for instance, the limited level of professional quality of medical examiners, the low degree of social service and the under-utilization of medical resource, and the inferior degree of information construction. This article expounds the exploration of physical examination and its specific working way from three respects: reform the working way and adjust medical personnel structure, improve social service level with applied-information technology and the utilization of medical resource, accelerate the information construction with the application of information technology. By grasping the key factors and applying our new methods and information technology, we have achieved good examination results.

Abstract: It was researched that the aviation embedded airborne software testing , because of software quality and reliability assurance.In order to improve the efficiency of testing of airborne software, for airborne software features, this paper propose a method that achieves the coverage test and basic ways search taking compiler GCC technology to complete the program automatic instrumentation. The method leverages airborne software test process automation in terms of modifying compiler GCC to make instrumentation automatically.

Abstract: IMA (Integrated Modular Avionics) system has been widely adopted by a new generation of aircraft. It with high complexity and integration will bring a new challenge in software testing. In this paper, it states what IMA is and how IMA system works. Because of isolation between partitions, the inter-partition communication is required to exchange information between the partitions. It also presents an integrated testing strategy based on UML sequence diagram according to the inter-partition integration of IMA. The method of test sequences generation is discussed emphatically. Finally, a case study is presented to testify the feasibility of our approach.

Abstract: As the technology further mature and improvement of social perception, face recognition technology will be applied in more fields. This paper apply the new technology human face recognizing to E-Learning, The realization of this system can make up for the mandatory authentication security deficiencies in the online learning system and effectively solve the student login "imposter" and "desertion" problem in the process of learning.

Abstract: Query expansion is one of the key technologies for improving precision and recall in information retrieval. In order to overcome limitations of single corpus, in this paper, semantic characteristics of Wikipedia corpus is combined with the standard corpus to extract more rich relationship between terms for construction of a steady Markov semantic network. Information of the entity pages and disambiguation pages in Wikipedia is comprehensively utilized to classify query terms to improve query classification accuracy. Related candidates with high quality can be used for query expansion according to semantic pruning. The proposal in our work is benefit to improve retrieval performance and to save search computational cost.

Abstract: Currently, RF technology for applications in logistics management, national research institutions and researchers devoted considerable effort. We also used some foreign advanced technologies in order to come to launch their own products, such as Shanghai Petrochemical BPM technology and logistics system will combine the ZigBee technology, the magnitude of such a system and application level information management further spread, which is the use of white sand and logistics jobs demand RFID technology to access cargo management, cargo inventory, position adjustment step, the basic realization of innovative research in the warehouse management system. Therefore, in the current intelligent warehouse management systems, wireless communication network technology applied to the management system has become an inevitable trend, on the one hand due to the wireless network can provide greater flexibility and mobility, in terms of eliminating a lot of wiring cost and effort, on the other hand it is more in line with internal information storage system data communications features in the future wireless network communication technology will further forward, so it will be able to greatly promote intelligent storage systems, networking process.

Abstract: To improve the efficiency of engineering spot attendance and employee management, a novel integrated management system is designed. The system uses a three-tier logical architecture design, which can be divided into user interface layer, business logic layer and data store layer. The realization of information management is based on VB6.0 and ACCESS database programming technology. The development of attendance information gathering functions of engineering spots is based on radio frequency identification technology and non-contact IC card. The separation of business logic and user interface makes the system more security and extensible. Experimental results show that the system has high efficiency, and it has user-friendly, secure and practical advantages.

Abstract: According to the management efficiency of material storages, a design scheme of automatic management system is designed based on radio frequency identification devices. The hardware platform of the system is realized based on nRF2401 and embedded computer technology. The software design of each subsystem is achieved by using the middleware technology of radio frequency identification devices and embedded software development and database programming technology. The field trial experiments and the laboratory testing results indicate that the system can realize effectively the automatic identification and management of material storages. It can improve the operation efficiency and greatly enhance the automation level of material storages management and save the cost of management.
