Using piecewise linearity system theory,the harmonic excitation nonlinear response of clearance restriction cantilever beam system was researched.

Based on a model of a cantilever beam system with clearance restriction,its nonlinear dynamic response to harmonic excitation are studied qualitatively in experiments.

The Study of the Shortest Paths in Transportation Network Under Time Constraint;

Considering that the methods for emergency drilling performance assessment are very rare presently,a new method based on time constraint model is put forth according to the traits of emergency drilling.

Feasible paths algorithm in distribution network based on time constrain;

An improved algorithm for mining sequential patterns with time constraints;

This paper concerns with military logistics distribution center location problem in which military users have their time constrain.

The paper investigates a multi-item ordering model of non-linear programming,which considers incremental quantity discounts with space constraint.

Through rob-based access control model(RBAC)and its extension study,put forward mandatory time and space constraints and role- based access control model(MSTEBAC)in the application of e-government system,this model introduce mandatery,time-bound,space constraint management methods based on the RBAC model,its security is maturity,authorization is flexible,actualization is simple.

The 1-1 Automatic Negotiation Strategy Based on Time Constraints;

Model and Heuristic Algorithm for Distribution System Based on Time Constraints;

This kind of model is used in the process of unit updown transitions with time constraints.

The proposed algorithm is implemented by incorporating the MRF based spatial constraints as a regularization term to the objective function of the kernelized fuzzy C-means clustering(FCM).
