This paper deals with the application of illustrative line renderings on endoscopic views. We examine different line drawing concepts and assess the ability to represent interior branches as well as specific anatomic features. Furthermore, we conduct a qualitative evaluation to rate the results of different illustrative visualization methods. We evaluate how well branches are depicted according...

The computational method based on using the operational matrix of anorthogonal function for solving variational problems is computeroriented. In this approach, a truncated Hartley series together withthe operational matrix of integration and integration of the crossproduct of two cas vectors are used for finding the solution ofvariational problems. Two illustrative...

Based on the fact that face-to-face and virtual meetings in organizational units increasingly take place in today’s business processes, it is not surprising that a lot of valuable information is generated during such events. Further, meeting information can be a valuable knowledge source for teaching and learning activities, e.g. it can support trainers and teachers in identifying emerging topi...

‘New Macsyma 2.2 Math Software understands plain English’. ‘We believe Macsyma 2.2 can halve the time and energy required to solve problems with math software’ (Richard Petti, President, Macsyma Inc.) This article looks at some of these advertising claims and considers the potential for such features as an aid in the teaching of mathematics to mathematicians, engineers and scientists. In a shor...

In this paper, we propose a method to approximate the solution of a linear Fredholm integro-differential equation by using the Chebyshev wavelet of the first kind as basis. For this purpose, we introduce the first Chebyshev operational matrix of integration. Chebyshev wavelet approximating method is then utilized to reduce the integro-differential equation to a system of algebraic equations. Il...

Abstract The use of visual materials in education is a traditional way teaching. Images are one the many kinds teaching methods used by teachers order to enrich their lessons and revitalise they teach. utilisation illustrative material when depends on factors. One these instruction training teachers. This study aims investigate influence teachers’ profile images lessons.

This paper introduces a new user-friendly MATLAB based-on program for dealing with the most important curves appearing in CAGD, as Bézier and B-splines curves. Since its user interface has been carefully designed, the program is specially recommended for educational purposes and it has been successfully applied for teaching both ungraduate and graduate students. The paper also discusses the mai...
