Against these deficiencies,a mathematical model of all parameters full constraints optimization of reinforced concrete frame structure design was established in this paper.

Bidding strategy adjustment considering system security constraints;

Weak network configuration and security constraints have great impact on the bid and bargain of regional electricity market.

And the security constraints transmission and the validation of security are presented.

Through analyzing the characteristic and security of information systems,this work presented the fundamental elements and their operation relationships,and the "need","permit","can" security constraints between the elements.

On the basis of the present condition of the integrated telecontrol center,in the paper,we researched the project of the telecommand security constraints system and analyzed these aspects such as the control logic,constraint mechanism and workflow control etc.

The generation scheduling program with security constraint is proposed,and its processes are also introduced.

Two trajectories in batch process can be matched reasonably in endpoint constraints, different local continuity constraints (Itkura constraint, Sakoe Chiba constraint) and different global constraints (Itkura constraint、Sakoe Chiba constraint) respectively, and minimum normalized total distance between two trajectories can be obtained based on dynamic time warping, then optimal path can be foun.

The concept of constrained clustering,classify the constrained conditions into global constraints,instance constraints and others constraints according to the application of constraints are presented.
