V2 June 2014. To say that the subject of VTE prophylaxis in orthopaedic surgery is a thorny issue may be understating the case. Debate and difference of opinion is something which is part and parcel of orthopaedic surgery and one of the many. components that makes this specialty fascinating.
A function is called strictly concave if. for any t in (0,1) and x â  y. For a function f: R â R, this definition merely states that for every z between x and y, the point (z, f (z)) on the graph of f is above the straight line joining the points (x, f (x)) and (y, f (y)). Any affine function is both (non-strictly) concave and convex. 2  The sine function is concave on the interval. 3  The function, where is the determinant of a nonnegative-definite matrix B, is concave. 4  Practical example: rays bending in computation of radiowave attenuation in the atmosphere.
General Syntax of Pure Virtual Function takes the form: The other concept of pure virtual function remains the same as described in the previous section of virtual function. To understand the declaration and usage of Pure Virtual Function, refer to this example: Since the above example has no body, the pure virtual function example() is declared with notation =0 in the base class Exforsys. The two derived class named Exf1 and Exf2 are derived from the base class Exforsys. The pure virtual function example() takes up new definition. In the main function, a list of pointers is defined to the base class.
