The August 29 issue of the Journal will include the first in a series of review articles on critical care. Critical care is a young specialty that is generally considered to have developed from the successful use of invasive ventilation during the 1952 polio epidemic in Copenhagen. In his report of the response to that epidemic, Ibsen described much more than the use of invasive ventilation; he...

I N THEIR ARTICLE "Visions and Revisions: A Special Education Perspective on the Whole Language Controversy," the authors describe two highly polarized approaches to reading instruction: whole language and direct instruction. This topic is of special importance and interest to us because, like the authors, we have been working in special education settings with teachers who have been trying to ...

Given n red and n blue points in the plane and a planar straight line matching between the red and the blue points, the matching can be extended into a bipartite planar straight line spanning tree. That is, any red-blue planar matching can be completed into a crossing-free red-blue spanning tree. Such a tree can be constructed in O(n log n) time. keywords: geometric graph, spanning tree, color

Consider a planar straight line graph (PSLG), G, with k connected components, k 2. We show that if no component is a singleton, we can always find a vertex in one component that sees an entire edge in another component. This implies that when the vertices of G are colored, so that adjacent vertices have different colors, then (1) we can augment G with k−1 edges so that we get a color conforming...

Optical character recognition (OCR) is becoming a powerful tool in the field of Character Recognition, now a days. In the existing globalized environment, OCR can play a vital role in different application fields. Basically, OCR technique converts images into editable format. This technique converts images in the form of documents such as we can edit, modify and store data more safely for longt...
