A 24-year-old female was seen with multiple, pinkish to skin colored and brownish to black pigmented macules, papules, patch and plaque on the face, neck, upper chest, extensor surface of both forearms and dorsal hands. Histopathological diagnoses from the 75 skin biopsy specimens taken during the follow-up period of 22 months include 29 skin tumors : one malignant melanoma, one precancerous melanosis, 16 basal cell carcinamas, four squamous cell carcinomas, four actinic keratoses, one melanoacanthoma, one keratoacanthoma and one angiofibroma. It was discussed that melanoacanthoma would be considered as the one of the associated beniign skin tumors in xeroderma pigmentosum.

This work is concerned with the development of digital contouring controller for multi-axial servosystems. Digital optimal contouring controller is proposed to coordinate each of the controllers of multiple feed drives and specifically improve the contouring performance. The optimal control formation includes the contour error explicitly in the performance index to be minimized. The contouring control is exercised for straight line and circular contours. Substantial improvement in contouring performance is obtained for a range of contouring conditions. Both steady state and transient error measures have been considered. The simulation study presented has established the potential of the proposed controller to improve contouring performance.
