According to the characteristics of vegetable greenhouse, based on S-MAC protocol, this paper proposed a L-MAC protocol of low power loss. A dynamic duty cycle adjustment mechanism is designed in the protocol, through the network traffic prediction to dynamically adjust the duty cycle to accommodate changes in network traffic. Finally, by the simulation analysis, the validity of the agreement is to verified.

This paper presents a new system of indicators for ecological assets assessment and a method for evaluating ecological total assets. With Remote Sensing images of Pudong New Area in 1998 and 2005, we got down to calculating vegetation coverage, Vegetation Net Primary Productivity (NPP) and adjustment factor. The distribution pattern of ecological assets of Pudong New Area in 1998 and 2005 as well as the ecological environment degradation between them were analyzed and mapped using DEM, meteorological and mentioned ancillary data. The whole area was finally divided into five: fast-growing area, moderate growth area, basically maintained area, moderately degraded area and severely degraded area, of which the basically maintained areas account for a large proportion, however, there are a majority of degraded areas, and the growing areas don’t reach to 10%. Which reveal the ecological environment in Pudong New Area actually and tell us to spare no efforts to making friends with our nature.

Based on the DCS configuration software, an implemented method was described in this paper. On the basis of the analysis of DCS configuration file, the configuration model and the initialization conditions of some power unit were established. Combined with embedded ARM technology, the intelligent front-end had realized the DCS control function through the run and scheduling module in the Linux system. The intelligent front-end could communicate with the supervisory computer by the communication module by which the supervisory computer ensured the maneuverability and control of the intelligent front-end. At last, the application of the intelligent front-end in the filed of intelligent devices such as actuators, intelligent instrument and sensor etc, was put forward, so as to realize the diversification of the DCS control function.

Since keyword-based search engine usually return large amount of results in which there are many unrelated documents and many documents with same content, automatic clustering technology is used to classify the retrieval results. While there are large amount of Web retrieval results, the clustering process usually costs long time and the clusters are not friendly to users since there are still many documents with same content. This paper proposed an improved clustering method by removing the duplicate documents from retrieval results. The removal operation is executed first in initial partition stage during clustering. Then it is executed again after the initial partition stage to remove the duplicate documents thoroughly. We proposed an efficient removal method in this stage. At last, we made experiment to verify our method.

A small electromagnetic pulse (EMP) simulator is designed in this paper. Its maximum height is 240mm. The simulator provides the simulated high electromagnetic pulse (HEMP) environment for testing smaller objects, under the condition of low source power. It adopts electromagnetic field modeling software Micro Stripes to analyse property of the simulator. Results of simulation show that the electric field distribution in the working volume is uniform under the excitation of double exponential voltage pulse (peak voltage of the pulse is 1.5kV). The property of small bounded wave EMP simulator satisfies demand of relational standards. It is enough for testing smaller objects. The results also shows that the transition section plays a more important place in the whole process.

Suitability evaluation for eco-tourism is the basis of eco-tourism planning and development. Based on the multi-factors evaluation approach and landscape visual sensitivity analysis, the ecological suitability for eco-tourism in Qipanshan was evaluated using GIS technology. We chose seven factors, including topography, land use, distance to nearest reservoir, distance to nearest roads, landscape visual sensitivity to reservoir, landscape visual sensitivity to rivers and landscape visual sensitivity to attractions. Result of ecological suitability evaluation was classified into five grades: the most suitable area, suitable area, relatively unsuitable area, unsuitable area, and the most unsuitable area. Result indicated that the most suitable and suitable area accounted for 41.7% of the total area, which suggested that the eco-tourism resource in study area is relatively abundant. The study area is suitable for eco-tourism development. 27.0% of the total area was relatively unsuitable area and can be developed as eco-tourism zone. Environment protection should be paid attention while the eco-tourism construction was carried out. The introduction of landscape visual sensitivity to the suitability evaluation enriched the planning theory.

This paper presents an improved fourier algorithm which is free of the effect by decaying dc component. Simulation results indicate that the new algorithm can effectively inhibit the decaying am periodic components in power system transient state. The new method can be used in power system relay protection to calculate the amplitude and phase angle of each harmonic component.

Various approaches are presented to solve the spreading spam problem. However, most of these approaches can not flexibly and dynamically adapt to spam. This paper proposes a novel approach to counter spam based on trusted behavior recognition during transfer sessions. A behavior recognition of email transfer patterns which enables normal servers to detect malicious connections before email body delivered, contributes much to save network bandwidth wasted by spam emails. An integrated Anti-Spam framework is designed combining the trusted behavior recognition with Bayesian Analysis. The effectiveness of both the trusted Behavior recognition and the integrated filter are evaluated.
