In order to insure the quality of battlefield information guarantee, promote efficiency of data management, and mining these values of data, a data management approach for battlefield data of targets and environment is studied in this paper. Concepts of targets and environment are introduced, these originals of data are discussed and classified, and these characters of data are analyzed. By describing data processing, establishing an organization, grading data qualities, the data of targets and environment is incremented in this processing with a data management standard system of system and the information recommending services base-on knowledge. An example is introduced to illustrate the data management process vividly. Finally the suggestions to improve data management are given. Empirical results show that the approach can insure qualities of information guarantee, promote efficiency of data management and increment data value.

In order to solve the aircraft targets segmentation and recognition problem with background interference in remote sensing images, a base-on granular computing method to division texture is used in this paper. By granulating remote sensing images, the gray level co-occurrence matrix and Gabor filter can catch these characters in elementary granules. And these elementary granules are incorporated to a result of texture division in quotient space. For illustration, a remote sensing image with two aircraft targets is utilized to show these steps of segmentation. Empirical results show that the decision rule with highest confidence measure will be used as the final decision rules in the MADA problem with multiple conflicting decision attributes. The base-on granular computing texture characters segmentation method can effectively solve the aircraft targets segmentation and recognition problem with background interference in remote sensing images are solved. © 2011 IEEE.

Visualization of highway traffic environments in virtual reality plays a key role on fidelity of simulation and validity of driving behaviors in driving simulator studies. This paper describes a procedure to replicate a signalized intersection with many complex features into a driving simulator's 3-D databases through building a graphical visual database, constructing a road motion database, and creating simulated traffic. The validity of the visualization was assessed via the comparison of the drivers' speeds in the simulator and the speed data at the real intersection. It was found that both speed data follow normal distributions and have equal means for each intersection approach;however, that the speeds measured in the driving simulator have a larger variability than those measured in the field. The users' subjective evaluation results indicated that 92% subjects could recognize the simulated intersection in the driving simulator experiment. Therefore, the strategy of geo-specific environment modeling would be useful for studying driving behaviors in virtual environments.

Multi-project and multi-attribute decision making can be characterized as a process of overall coordination and optimization. Through the application analysis of decision making, the analysis process of decision making are projected on basis of targets, methods and evaluation;then with the combination of qualitative and quantitative methods and consideration of the features of exponential model, interval ergodic analysis method is proposed and finally established. The evaluation model to be structured on basis of the method gets multiple projects and attributes involved, and conducts ergodic calculation on condition of the given target criteria and certain region of each attribute so as to get the evaluation of the multiple projects accomplished. At last, a case study is provided in order to further elaborate the application of the analysis procedures of decision making and the interval ergodic analysis method in the multi-project and multi-attribute decision making.

For the purpose of achieving high-performance information sharing in the simulation grid, an information capability-based Three Phase High-performance Information Sharing Approach (TPHPISA for short) is advanced. The main idea of TPHPISA is selecting those information sources with highest information capability and executing the best query plan. To illustrate how TPHPISA works, an application example of implementing high-performance information sharing in the stock market simulation grid is thoroughly analyzed. At last, the searching efficiency and accuracy of TPHPISA are demonstrated through comparing with other similar method. © 2010 IEEE.
