Because the model on whose output the objective forecast was made updates frequently now, and relation between some forecast factors and PFP is nonlinear, a new method, dynamically combined equation of nonlinear multi factors (DCENMF), is presented to .

Aiming at the current way of teaching prevailing in physical education in the general university of higher learning and the consequent problems ,the paper discusses an application of what is termed "option section teaching approach ",namely the dynamic combination in which teachers ,students and teaching materials interact.

The dynamic combination of Web services enable the system to realize services system re-configuration based on environmental need,and thus enhances survivability of the system.

Based on the current Web services of dynamic combination research, an approach to Web services combination of static and dynamic composition was proposed.

Research and implementation of web services dynamic composition based on SOA;

Study on web services dynamic composition based on MDA

In this thesis,focus on the implementation of Petri net theory in Web services composition,describing how to achieve the integrated Web services based on Petri net modeling dynamic composition of Web services.

The state compounding method and control strategy applied in voltage mode PWM inverter is presented.
