In this contribution, we describe the potential of SDR4all (Software Defined Radio for all) to solve the bottlenecks and reduce the innovation cycle related to the design and implementation of flexible radio algorithms. SDR4all is a programmable software tool with radio cards for wireless researchers, students and engineers. It enables to implement in software any wireless scheme between two la...

We present nrgrep (\nondeterministic reverse grep"), a new pattern matching tool designed for eecient search of complex patterns. Unlike previous tools of the grep family, such as agrep and Gnu grep, nrgrep is based on a single and uniform concept: the bit-parallel simulation of a nondeterministic suux automaton. As a result, nrgrep can nd from simple patterns to regular expressions, exactly or...

There are many diverse algorithms for generating a first mesh, refining it and improving it. A tool that allows us to interchange these algorithms according to the requirements of the problem at hand and also to incorporate new algorithms, needs to be flexible. This paper presents an object-oriented design approach for a meshing tool that provides these flexibility features by encapsulating pro...

Finding new families of distributions has become a popular tool in statistical research. In this article, we introduce a new flexible four-parameter discrete model based on the Marshall-Olkin approach, namely, the discrete Kumaraswamy Marshall-Olkin exponential distribution. The proposed distribution can be viewed as another generalization of the geometric distribution and enfolds some importan...

Modern operating systems must support a wide variety of services for a diverse set of users. Designers of these systems face a tradeoo between functionality and performance. Systems like Mach provide a set of general abstractions and attempt to handle every situation, which can lead to poor performance for common cases. Other systems, such as Unix, provide a small set of abstractions that can b...

Prior-art retrieval is a crucial application of Patent Retrieval aimed to determine the novelty of a new invention. In this scenario patent authors require an exhaustive knowledge of all related patents and the search often involves multiple patent collections across the world, which do not share the same document structure or vocabulary. For this reason, despite of the numerous patent search a...

Business processes of modern companies are characterized by a huge complexity which is caused for example by quickly changing markets, short product life cycles or dynamic interactions between particular subsystems of a company. Business process management is intended to implement efficient and customer-oriented processes whereby the simulation of business processes can be used to evaluate the ...

High-throughput assays generate immense quantities of data that require sophisticated data analysis tools. We have created a freely available software tool, SLIMS (Small Laboratory Information Management System), for chemical genetics which facilitates the collection and analysis of large-scale chemical screening data. Compound structures, physical locations, and raw data can be loaded into SLI...
