Wireless Networks In-the-Loop can significantly cut the time needed to develop a fully functional wireless communication system. By introducing a virtual RF front-end and a virtual radio channel, which integrate seamlessly with already existing software radio projects, simulations can be run in lieu or in conjunction with real-world tests. The following pages describe a solution and implementat...

Few studies have assessed the common, yet unproven, hypothesis that an increase of plant nitrogen (N) uptake and/or recovery efficiency (NRE) will reduce nitrous oxide (N2O) emission during crop production. Understanding the relationships between N2O emissions and crop N uptake and use efficiency parameters can help inform crop N management recommendations for both efficiency and environmental ...

The Miller-Rabin pseudo primality test is widely used in cryptographic libraries, because of its apparent simplicity. But the test is not always correctly implemented. For example the pseudo primality test in GNU Crypto 1.1.0 uses a fixed set of bases. This paper shows how this flaw can be exploited to break the SRP implementation in GNU Crypto. The attack is demonstrated by explicitly construc...

This month we continue our discussion of graphics in R. This month we examine histogram generation, 1-D and 2-D kernel density estimation. The GNU S language, "R" is used to implement this procedure. R is a statistical programming environment that utilizes the S and S-Plus language developed at Lucent Technologies. In the following document we illustrate the use of a GNU Web interface to the R ...

This report analyzes aspects of the Cognitive Radio for the purpose of research by educational institutions. The main focus is to understand the relationship between hardware and software components currently being used in this field of research. The software chosen was the open source GNU Radio, which is the primary software used in several researches in Stevens Institute of Technology. Severa...

Random number generators are critically important for computational statistics. Simulation methods are becoming ever more common for estimation; Monte Carlo Markov Chain is but one approach. Also, simulation methods such as the Bootstrap have long been used in inference and are becoming a standard part of a rigorous analysis. As random number generators are at the heart of the simulation-based ...

SUMMARY Elementary modes analysis is a powerful tool in the constraint-based modeling of metabolic networks. In recent years, new approaches to calculating elementary modes in biochemical reaction networks have been developed. As a consequence, the program Metatool, which is one of the first programs dedicated to this purpose, has been reimplemented in order to make use of these new approaches....
