Research on technologies of constraint-based conflict detection in collaborative design;

To improve the efficiency and scalability of conflict detection for multi-dimensional classifiers,a new algorithm,based on grid of trie(GoT) algorithm,was proposed.

Research on security policy collision detection module based on multi-domain environment;

Active rule technology in collision detection;

Cloth-body collision detection is essential to study apparel animation,but the developed hierarchical methods are hard to meet the requirement of real-time detection since clothes belong to deformable objects,which require frequent hierarchy updates.

Effect of sample kind, samlpe size, experimental liquid, vacuum in the container and experimental temperature on testing result of true density of refractory were studied and testing data was analyzed , It showed that accuratity of testing result can be ensured by using proper method.

The analytic result is that both "keep secret" and "report to the leadership"of testing results are important and their relationship is the key resolution.

Combined with the experience of highway testing,the author analyzes the factors influenced testing result of asphalt content test from sampling method of hot-mixed bituminous mixture,detection method of mineral powder s quality in extracting solution,and water content of mineral powder,in order to improve the accuracy of testing and to ensure the quality of bituminous mixture.
