This paper describes an improved semaphore with policies in Windows operating system. We introduce policies to help operating system kernel select next process (or thread) in the waiting list queue to satisfy. The paper present live policies: first in first out (FIFO), first in last out (FILO), highest priority first out (HPFO), lowest priority first out (LPFO) and random. We discuss the design and...
In this paper, we provide the degree reduction algorithm for negative degree Bezier curves. By the uniform parameterization of control polygons and the definition of discrete derivatives of piecewise linear functions, we prove that the degree reduced control polygons and their discrete derivatives converge in the limit to the original negative degree Bezier curve and its continuous derivatives.
The abstract monotone iterative technique is well know and very important for applications to a variety of situations. With partial order defined in metric space, the purpose of this paper is to discuss the existence of coupled fixed point for mixed monotone mapping pairs. The results are quite different from the results in recent references. The paper also gives two examples to illustrate the theorems...
A new algorithm for clipping a line segment in two dimension against a rectangular window is presented in this paper. The algorithm are different to the others of line clipping algorithms. This algorithm use the affine transformations (Shearing transformations) to transform the line segment and the window, which make the process of clipping the line segment very simple and avoid solving the equations...
