Define Image?
An image may be defined as two dimensional light intensity function f(x, y)
where x and y denote spatial co-ordinate and the amplitude or value of f at any point
(x, y) is called intensity or grayscale or brightness of the image at that point.

A Free Body Diagram is a pictorial representation often used by physicists and engineers to analyze the forces acting on a free body. A free body diagram shows all contact and non-contact forces acting on the body. Drawing such a diagram can aid in solving for the unknown forces or the equations of motion of the body. Creating a free body diagram can make it easier to understand the forces, and moments, in relation to one another and suggest the proper concepts to apply in order to find the solution to a problem. The diagrams are also used as a conceptual device to help identify the internal forces, (for example shear forces and bending moments in beams), which are developed within structures

Joint replacement involves surgery to replace the ends of bones in a damaged joint. This surgery creates new joint surfaces.
In shoulder replacement surgery, doctors replace the ends of the damaged upper arm bone (humerus) and usually the shoulder bone (scapula) or cap them with artificial surfaces lined with plastic or metal and plastic. Shoulder joint components may be held in place with cement, or they may be made with material that allows new bone to grow into the joint component over time to hold it in place without cement.

JOINT REPLACEMENT SURGERY
Joint replacement is one of the most common and successful operations in modern orthopaedic surgery. It consists of replacing painful, arthritic, worn or diseased parts of the joint with artificial surfaces shaped in such a way as to allow joint movement.
Arthroplasty is a common but loose term for joint replacement. Other types of surgery are also arthroplasties. Other common and valid synonyms are total joint replacement, total joint arthroplasty, joint resurfacing and artificial joint surgery.

According to a recently released Japanese study, drinking several cups of green tea a day may work as a natural anti-depressant for older men and women, adding yet a another healthful boon to the increasingly researched wonder beverage.
Researchers at Sendai’s Tohoku University Graduate School of Biomedical Engineering found that elderly people over the age of 70 who drank four or more cups of green tea per day were 44 percent less likely to struggle with depression than those who drank less than four cups.
