This paper studies the problem of generating optimal guided bomb delivery trajectories on-board for a fixed-wing Unmanned Combat Aerial Vehicle (UCAV). First, a high-fidelity nonlinear 3 Degree-Of-Freedom (DOF) aircraft model is built, which takes platform kinematic and dynamic constraints into account. Second, for the sake of integration of weapon delivery constraints into the problem formulation, an approximate elliptic Launch Acceptable Region (LAR) model is introduced. Third, a new optimal control method - Gauss Pseudospectral Method (GPM) is used to transform the trajectory planning problem into a nonlinear programming problem. To improve computation efficiency and reduce the complexity of initial guess, a multistage iterative optimization strategy is presented. Finally, simulation results demonstrate the efficiency of the method.

Trajectory generator is necessary in many inertial navigation research fields. The paper gives the design method of a trajectory generator, and deduces the control equation in detail, then classifies the flight track into four fundamental stages. The trajectory generator resolves the flight track, generates specific force, angular velocity and position signals etc. To check the trajectory generator, the paper designs a navigation solution program. At last, a simulation is demonstrated; the data such as position information generated by trajectory generator and navigation solution equation is compared. Simulation shows that the design is correct and the precision of the trajectory generator is very high.

In recent years, the simulation platforms of unmanned helicopter usually express the flying state with data or curves. The flight display animation is rough, cannot accurately express the information of flight status. According to the present situation, this paper puts forward a way to build the high precision and visual simulation platform of the unmanned helicopter. It is using Visual C++ to write the software of the interface, parameter identification method to build the mathematic model with LeiHu Raptor 60 helicopter as model, 3Dmax to establish the helicopter animation model, Direct3D to realize the map making of flying scenes and the rendering of planes and environment, and Matlab as engine server to deal with motion equations and controller equations. The three dimensional animation intuitively shows the flying state, then greatly meets the needs of the visual analysis.

Studies of the bi-matrix game are mostly based on the assumption that all players are rational people. But research results are conflict with the realities. In this paper, putting emotional factors in game structure, in non-expected utility theory, we established RDEU-Bimatrix Game Model which containing players' emotional preference. Using the Brouwer fixed-point theorem proved the existence of Nash equilibrium in RDEU-Bimatrix Game Model. Finally, through the numerical analysis we discussed the influence of players' emotional preference for Nash equilibrium.

Fusion of multi-sensor observations of satellites would improve land surface monitoring. Physical-based model is the most popular method for retrieval of atmospheric and land surface parameters from remote sensing data for its applicability for large area, while empirical model is more efficient and requires fewer constraints. In this paper, a pixel-based quantitative fusion algorithm of multi-sensor observations with combination of physical and empirical model is presented. Firstly, the parameter was retrieved from one sensor data based on physical model, and then used to establish the pixel-based empirical relationships with measurements of another sensor. Thus, the two retrieval methods could be combined and the observations of two sensors could also be fused. The algorithm was applied to fuse MISR with multi-angular measurements and MODIS with high temporal resolution for retrieval of Leaf Area Index (LAI). The results were evaluated using field measurements in Changbaishan.

In this paper, due to select and evaluate difficultly operational plans in the joint operational commend decision, we propose a link-relative evaluation method based on the value analysis. The method evaluates operational plan s according to five factors of "impact force, mobile force, protecting force, information force and guarantee force", and supports the optimum operational plan by the expert information. The paper, taking example for selecting and optimizing joint operational plan, details basic principles and process of collecting and handling the expert information, and the application of the expert information to select the optimum operational plan. The method overcomes shortcomings of analytic hierarchy process and fuzzy evaluation technique.

This paper proposes a new method for the automatic generation of a digital terrain model (DTM) from airborne laser scanning technique. First, generate regular grids, and then filter the points on each regular grid. Finally, change the size of grid and filter these points on the new grids repeatedly. The data measured by LiteMapper-5600 in a city is used to evaluate the method. The results show that this method can remove most of non-ground points effectively and generate DTM with the high-accuracy in urban areas.

Texts, images, audio and video clips about products are important information for customers in shopping. However customers cannot have such information as soon as they see the products in physical stores. The authors propose a Fast Planar Object Detection in Multimedia Augmentation for Products system using mobile devices to provide useful information for customers when they go shopping. The experimental results show the strength of our proposed system in processing and displaying multimedia information on users' mobile devices in real-time. The system can be used as a smart assistant for customers to get extra useful information about products and help them decide the best choice for their demands.

This paper discusses the mathematical model depicting how Bursaphelenchus xylophilus infected pine trees. Firstly, according to the spread mechanism of communicable disease, we established a differential equation model with two species, i.e. pine trees and Monochamus alternatus Hop the--host of Bursaphelenchus xylophilus. Secondly, we studied the stability of system equilibrium under disease-free situations as well as disease-existing situations using Lyapunov Stability Theory. Last, we made several numerical simulations in order to test the correctness of our model. One merit of our work is providing theoretical basis for the practical control and prevention of this disease.
