A mathematical model for free-form solid modelling was presented in previous published works. The key aspects of this model are the decomposition of the volume occupied by the solid into non-disjoint cells, and the representation of the solid as an algebraic sum of these cells. Here we apply this scheme to represent CSG solids built by combining free-form solids in boolean operations. As a proo...

The current implementation of OpenGL only supports standard 1-D and 2-D texture mapping. An interface is proposed to extend the OpenGL library, to support a simpli ed model of antialiased procedural solid texturing in OpenGL version 1.1. This extension to the OpenGL language does not modify the existing OpenGL standard. It is designed as a supplemental library that works with existing implement...

The collected works of English mathematics educator, Mary Boole, might be invaluable for education and curriculum research that attempts to understand the question: “what counts as knowing?” Even though it was written before 1916, Boole’s work allows curriculum researchers and teacher educators interested in the question to experience a significant shift in thinking. For example, in the followi...

In this paper source-detector solid angle calculation has been studied by Monte Carlo method, and a computer program is represented. Since most experimental works in nuclear physics are done by using of cylindrical detectors, the solid angle of this type of detector is calculated for various sources. The source in various shapes of a point, cylinder, sphere, or rectangle, may be located in any ...

In my learning disabilities class each year, a student does a presentation on remediating reading comprehension problems. To prepare for the presentation, students read the most recent textbooks and articles that describe strategies to improve reading comprehension. At some point during the presentation, the student will say something like, "The ability to identify the main idea is crucial for ...

To read with joy and understanding, to learn and grow through reading, to read critically and thoughtfully are the goals of all reading programs. The way different programs approach these goals are what distinguish one program from another. Reading Mastery incorporates perhaps the largest variety of instructional techniques of any commercially developed reading program available. Some programs ...

Decision support tools exist for oncologic follow up. Their main interest is to help physicians improve their oncologic readings but this theoretical benefit has to be quantified by concrete evidence. The purpose of the study was to evaluate and quantify the impact of using dedicated software on RECIST readings. A comparison was made between RECIST readings without dedicated application vs. rea...

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this junos enterprise routing a practical guide to junos routing and certification, how can ...

There are several tasks where is preferable not responding than responding incorrectly. This idea is not new, but despite several previous attempts there isn’t a commonly accepted measure to assess non-response. We study here an extension of accuracy measure with this feature and a very easy to understand interpretation. The measure proposed (c@1) has a good balance of discrimination power, sta...
