A low-cost spectrum analyzer is presented, based on a commercial software defined radio and an open-source application package. Fundamentals regarding the receiving operation its sensitivity are along with measurements, of two 8 12-bits models. An application, run within GNU Radio, deployed to overcome hardware analog-to-digital converter limitation monitor wide bandwidths. Results shown for di...

This month we demonstrate the use of robust estimators of location using the GNU S-Plus language, "R". R is a statistical programming environment that is a clone of the S and SPlus language developed at Lucent Technologies. In the following document we will illustrate the use of a GNU Web interface to the R engine on the "rss" server, http://rss.acs.unt.edu/cgi-bin/R/Rprog. This GNU Web interfa...

This paper discusses the problems faced with interoperability between two programming languages, with respect to GNU Octave, and GTK API written in C, to provide the GTK API on Octave.Octave-GTK is the fusion of two different API’s: one exported by GNU Octave [scientific computing tool] and the other GTK [GUI toolkit]; this enables one to use GTK primitives within GNU Octave, to build graphical...

We describe in this paper the compilation scheme of the GNU Prolog system. This system is built on our previous experience of compiling Prolog to C in wamcc. The compilation scheme has been however redesigned to overcome drawbacks of the compilation to C. In particular, GNU-Prolog is based on a low-level miniassembly platform-independent language that makes it possible to avoid the phase of com...

Mule: MULtilingual Enhancement to GNU Emacs handles not only ASCII characters (7 bits) and ISO Latin-1 (8 bits), but also Greek, Cyrillic, He-brew, Thai, Vietnamese (8 bits), Japanese, Chinese, Korean (16 bits) coded in the ISO2022 standard and its variants (e.g. EUC, Compound Text). A text buffer of Mule holds a mixture of these languages. As for inputting, Mule provides various input methods ...

gperf is a “software-tool generating-tool” designed to automate the generation of perfect hash functions. This paper describes the features, algorithms, and object-oriented design and implementation strategies incorporated in gperf. It also presents the results from an empirical comparison between gperf-generated recognizers and other popular techniques for reserved word lookup. gperf is distri...

The GNu Ada Runtime Library (GNARL) is being developed to support Ada 9X tasking for the Gnu NYU Ada Translator (GNAT). Together, they form a portable, freely distributable Ada 9X translation system. GNARL and GNAT communicate through a well-deened procedural interface, facilitating their independent development. Among the design goals of this translation system are portability, interoperabilit...
