Vessel Width

A retinal vessel width measurement algorithm is presented towards ROP (Retinopathy of Prematurity) plus diagnostic automation. The algorithm involving geometrical feature extraction with the image processing is used to compute the effective width of the major vessels in a retinal image. Width measurement is shown to be a statistical parameter estimation related to the statistics of the retinal information. The algorithm is applied to the generic data bases available and the results are found to be satisfactory with ophthalmologist opinion. The effectiveness of the algorithm depends on the fundus image capturing settings.

Reviewing and analyzing insulation mechanism of high voltage wall bushing, the structure of 1100kV UHVDC wall bushing and its key technical parameters are designed according to work conditions. Insulation structure and electric field of key bushing parts are simulated by ANSYS11.0. And the solution is optimized by SubProblem method based on the DC field theory. The result indicated that the parameters of designed solution could meet the needs of 1100kV UHVDC power transmission project.
