A theoretical and experimental study of measurement of three dimensional Cartesian coordinates of the end effecter of a robotic manipulator with three different frames each one known relative to the other was carried out in this research.The aim of this work is, first, to calculate three dimensional Cartesian coordinates of an end effecter tip which lies in a specific frame {C} with respect to another frame which represents the fixed base frame {A} passing through an intermediate frame {B} by using Matrix Compound Transformation Method i.e. theoretical approach, then followed by measuring the same coordinates by another two traditional procedures, they are: Z A Y A X A P P P , , o Self Coordinates Feeding. o Manual Alignment. And comparing the final obtained results (theoretical and experimental) with the standard one. The second step is checking repeatability for the above mentioned methods, by measuring the final tip coordinates for 18 times for each case. The final result shows that the Matrix Compound Transformation Method gives an accurate repeatability comparing with the others.

Pericytes are vascular satellites present around capillary blood vessels and small venules. They have been observed in almost every tissue of the body and are thought to be related to vascular smooth muscle cells. Morphologically pericytes have great similarity to vascular endothelial cells and also slightly resemble myoepithelial cells.The present study describes the ultrastructural morphology of pericytes in normal breast tissue and in benign tumor of the breast. The study showed that pericytes are ovoid or elongated cells separated from the endothelial cell of the capillary blood vessel by the basement membrane of endothelial cell. The nuclei of pericytes are often very distinctive. Although some are round, oval, or elongated, others show marked irregularity and infolding of the nuclear membrane. The cytoplasm shows mono-or bipolar extension in which the cytoplasmic organelles are located (Fig. 1). These cytoplasmic extensions embrace the capillary blood vessel incompletely. The plasma membrane exhibits multiple areas of focal condensation called hemidesmosomes (Fig. 2, arrow). A variable number of pinocytotic vesicles are frequently seen lining the outer plasma membrane. Normally pericytes are surrounded by a basement membrane which is found more consistently on the outer plasma membrane separating the pericytes from the stromal connective tissue.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
