The occurrence regulation of Spodoptera litura was studied according to the continiuous years's data investigated in tobacco fields and weather data of Chenzhou and Ningyuan in Hunan. Results showed that generations of Spodoptera litura are 4–4.5 with the effective accumulated temperture per year and the actual generations of Spodoptera. litura is in accordance with the predicted generations in Hunan Province. The sources of Spodoptera litura in early stage of the year were migration pest, there were four occurrence stages in a year according the properties of pests sources, the number of trapped moths from April to June is significantly correlated with the number in March, the forecasting model is ŷ = 233.54 + 112.44x4 (r = 0.815∗, n = 8). The number of trapped moths from April to June is significantly correlated with the daily average temperture of January (reliability degree was 90%), the forecasting model is ŷ = −1410 + 350x(r = 0.595, n = 9).

Recently, an AC processing pickup has been proposed and used in range of applications from stage lighting to EV charging. This new pickup has the advantage of producing high efficiency AC output while retaining a simple circuit topology. However, the exactly analysis of these pickups has been rather difficult and time domain solutions in the form of transcendental equations are required to numerically solve for the steady state operation. This paper produces a set of normalized tables for all the dependent variable for this type of pickup, hence aiding engineers in the design process.

In the design of cockroach robots, a major requirement is to increase the carrying capacity of the robots. This paper proposes a novel configuration for the leg design of cockroach robots. In this configuration, the operating principle of a differential gear in a car is used in the design of multi-legged robots, so the carrying capacity is doubled at the same situation, compared with conventional linkage based robots. Firstly, the movement performance of the mechanism, including the inverse kinematics is analyzed and a decoupling algorithm is presented to control the prototype. Secondly, the working space and carrying capacity is calculated and analyzed. Then the whole model is simulated by the combination of MATLAB and ADAMS. The result of the simulation shows an improved performance, which indicates that the mechanism design is reasonable and the analysis is correct.

In order to reduce possible resonance induced by harmonics, this paper focus on analyzing sensitivity and stability of passive power filter (PPF) that plays an important role in hybrid active power filter (HAPF). To minimize the capacity of HAPF and forecast its stability, a power system analysis framework (PSAF) that is professional software for analyzing the power distribution system is used to analyze PPF based on Graph Theory. The filtering effect and ability to compensate reactive power is demonstrated by proposed method that is useful and suitable to any HAPF. Comparing to other methods, proposed method shows the advantages of approximately physical simulation and higher calculation precision due to designing detail system parameters. It is implemented in an HAPF with a 3000kVA that installed in a coal mill in Northern China. The simulation and measured results show that the proposed method is not only easy to be calculated and implemented, but also very effective in reducing harmonics and compensating reactive power.

This paper presents a 1kW inductive charging system for Electric Vehicles (EV's). The primary topology uses an LCL converter and the secondary topology uses a parallel AC processing pickup to produce a controllable current source ideal for EV battery charging applications. Standard circular pads with a diameter of 420mm were used. The system can operate over a variable charging height of 45–90mm. The measured efficiency from the AC mains socket to the DC battery is 73–83% at rated power conditions of 1kW depending on the relative height and alignment of the pads.

In view of the periodical tasks and emergent tasks transmitted in networked control systems, a bandwidth scheduling scheme with deterministic time-constraint is proposed. Based on task demands analysis, the limited network bandwidth is allocated to each transmission task properly by dividing time-window, setting priority of tasks and the initial transmission moment of each task. As a result, delay jitter is reduced and network bandwidth is used reasonably, which can guarantee the quality of network service. Finally, the simulation study of dual-cylinder pushing synchronous control system shows the effectiveness of the proposed scheme.

The main purpose of this paper was to develop a DNP3.0 protocol based on the high performance remote terminal unit (RTU) which was applied to the feeder automation system of substations. As the efficiency of architecture and instruction set of microcontroller was low, a higher operating frequency and larger memory microcontroller was utilized as the control core of early RTU to improve the efficiency, so the cost was increased. Therefore, the advanced microcontroller would be used as the control core, which employed the Harvard architecture and pipeline processing technology to improve the system efficiency. The RTU proposed by this paper could measure the voltage and current of the feeder, monitor the feeder line branch switch status, digital relay, and utilize DNP3.0 and feeder automation host machine, Feeder remote terminal unit (FRTU), communication. This paper has finished the development of the prototype of RTU to verify the feasibility of the architecture proposed.

A dynamic secret sharing scheme on general access structure is proposed based on bilinear maps. Combining it with the identity-based cryptography, a general threshold encryption scheme is proposed. The threshold encryption scheme can realize the secure transmission of secret in insecure channel, compared with other secret sharing schemes. This scheme is without secret exchange, so the decryption group changes according to the message importance level and this scheme can meet demand of the multi-task system. The security analysis shows that the proposed schemes have higher security.
