The analytical results for various boundary conditions were obtained by means of the generalized Levy method and state space technique, taking the lateral shear deformation into consideration.

Through the study of the method of security protocol analysis based on the Strand Space Model,this paper proposes an advanced state space reduction technique,which combines state space reduction techniques with pruning-theorems during the protocol analysis in order to reduce the state space more efficiently.

A method for ship technical condition evaluation based on D-S evidence theory;

A method for integrated evaluation of the technical condition of mechanical equipment based on close degree;

But with the change of new production requirement such as steel market and rational utilization of mineral resource,the new method for mining is pointed out,and the technical condition for meeting the single ore body stope capacity is emphasized.

Application of CAN bus in dynamic monitoring system of technical state of equipment;

The six characteristic parameters of diesel engine in different working conditions were measured and extracted by the experiment,the technical states were divided into five grades like better,good,general,bad and worse,and the reference characteristic vector under each grade was determined.

This paper outlines the main assessing methods and the main assessing systems for the technical state of existing bridges, and comments on the current assessing systems and their shortcomings.

Basic Research of Vehicle Technology Condition Remote Monitoring & Diagnosis;

After analyzing the necessity of research on diesel engine technology condition remote monitoring & diagnosis this paper firstly constructs the system of diesel engine technology condition remote monitoring & diagnosis based on the actuality of the correlative technology.

The probability model to evaluate the grade of technical conditions of rolling stock is set up.
