In this paper we introduce Nath, a LTEX 2.09/2ε style implementing a natural TEX notation for mathematics. keywords: Natural mathematical notation

The calc package reimplements the LTEX commands \setcounter, \addtocounter, \setlength, and \addtolength. Instead of a simple value, these commands now accept an infix notation expression.

In the gastrointestinal (GI) tract endoscopy field, ingestible wireless capsule endoscopy is emerging as a novel, minimally invasive diagnostic technology for inspection of the GI tract and diagnosis of a wide range of diseases and pathologies. Since the development of this technology, medical device companies and many research groups have made substantial progress in converting passive capsule...

This paper describes the fontspec package for the X E TEX–LTEX format which provides a high level interface for font selection and configuration of OpenType, and other, fonts.

878 NOTICES OF THE AMS VOLUME 42, NUMBER 8 Technical writing, and mathematical writing in particular, is a complex and difficult task. While a number of excellent articles have been devoted to mathematical writing, few if any address issues concerning the use of computer technology. The aim of the present article is to draw the reader’s attention to existing works on mathematical writing, to of...

This document describes some new commands for the picture environment of LATEX. Some of the picture drawing commands of LATEX are very low-level. New higher-level commands are implemented and described here. These commands enhance the graphic capabilities of LATEX and provide a friendlier and more powerful user interface than currently existent. Their implementation has been done with the aim o...

3D surface classification is a fundamental problem in computer vision and computational geometry. Surfaces can be classified by different transformation groups. Traditional classification methods mainly use topological transformation groups and Euclidean transformation groups. This paper introduces a novel method to classify surfaces by conformal transformation groups. Conformal equivalent clas...

in this paper we study the module contractibility ofbanach algebras and characterize them in terms the conceptssplitting and admissibility of short exact sequences. also weinvestigate module contractibility of banach algebras with theconcept of the module diagonal.

The Sweave system of Leisch (2002) is a literate programming tool based on ideas of Knuth (1984) and is currently part of the core R installation. Specifically, Sweave is a system for processing documents that mix LTEX document formatting with R code. R code can be interspersed within the LTEX markup by indicating “code chunks”. These code chunks are evaluated by the Sweave function in R and th...
