Following rapid expansion of huge agriculture information body on the Web, the efficient agriculture information gathering on specified top becomes more and more important in search engine research. Through the statement of the developing trend of search engine and sharing agriculture information resource, this paper discusses the necessity of building search engine for agriculture information. The author clarifies the working principles of professional search engine for agriculture and finally analyses the improvement of searching technique of agriculture and proposes a model for agriculture - focused search.

In this paper, we present a Bandwidth Degradation QoS scheme for Adaptive Multimedia services in next generation Wireless/Mobile networks, and introduce it in mobile networks to improve the performance of channel allocation. The proposed schemes are the generic Call Admission Control (CAC) algorithm and the admission policy to support multiple rates, multiple class traffic of next generation mobile network. Based on diverse QoS parameters be included in connection request, a Two-Stage Bandwidth Degradation QoS CAC algorithm is presented to satisfy the diverse QoS requirement and utilize the system resource efficiently. The simulation results show that the performance of our scheme is preferable to that of existing schemes.

The rapid growth of agriculture web information brings a fact that search engine can not return a satisfied result for users' queries. In this paper, we propose an agriculture domain search engine system, called ADSE, that can obtains results by an advance interface to several searches and aggregates them. We also discuss two key technologies: agriculture information determination and engine.

According to the research status of regional agriculture industry structure adjustment information system and the current development of information technology, this paper takes web-based regional agriculture industry structure optimization tool as research target. This paper introduces Ajax technology and related application frameworks to build an auxiliary toolkit of decision support system for agricultural policy maker and economy researcher. The toolkit includes a "one page" style component of regional agriculture industry structure optimization which provides agile arguments setting method that enables applying sensitivity analysis and usage of data and comparative advantage analysis result, and a component that can solve the linear programming model and its dual problem by simplex method.

This book constitutes Part II of the refereed four-volume post-conference proceedings of the 4th ifip TC 12 internationalconference on computer andcomputingtechnologies in agriculture, CCTA 2010, held in Nanchang, China, in October 2010. The 352 revised papers presented were carefully selected from numerous submissions. They cover a wide range of interesting theories and applications of information technology in agriculture, including simulation models and decision-support systems for agricultural production, agricultural product quality testing, traceability and e-commerce technology, the application of information and communication technology in agriculture, and universal information service technology and service systems development in rural areas.

The research states home and abroad of the winnowing technology and winnowers are reviewed in brief. For the air duct, the core component of the winnower, the relevant technical parameters in the winnowing process are calculated based on the winnowing principle. The three-dimensional computer aided design (3D-CAD) software Solidworks is applied. The designed vertical winnower is able to separate different raw materials by adjusting the air speed and has been put into practical production to separate the Chinese traditional medicine with high separating effect.

To level up the application of wireless sensor network in cotton field soil monitoring, wireless sensor network technology has been studied deeply. Some difficulties, including the design of soil moisture sensor, covering problem in wireless sensor network and diagnosis algorithm for wireless sensor networks and node, are been proposed and discussed. Combined with cotton field soil moisture monitoring application, coverage and deployment based not only on plane space but also on time are been discussed and a fault diagnosis algorithm based on entropy is been put forward in the article.
