QueueSimulator is a free software which aims to simulate primarily G/G/k queueing systems that are used in computer networks. But it can be used to simulate practically any stable queue system.

R-gregmisc is a set of extension package for the open-source statistical environment/language "R''. It includes functions for plotting (gplots), data manupulation (gdata), modeling (gmodels), and programming tools (gtools), creation and management of sub-processes (fork), determing sample sizes for -omics experiments (ssize), and a variety of other packages.

The R package to be built aims at implementing what I did in a few scripts for the preparation of the papers I published in CaGEO and TGIS (see below). Basically this is related to the computation of the distribution of k co-occurrences of spatial events (generalising the contiguity distributions - 2 co-occurrences at distance 0) to derive spatial clustering statistics (mainly using the Shannon entropy, then called the k-spatial entropy) and methods linked to this: SOOk, SelSOOk (see caGEO paper) and scankOO (see TGIS). Another method (CAkOO) performing a k-Correspondence Analysis (i.e. on a multiway table with k entries) on the contingencies of co-occurrenceshas been already "published in my JSS paper about another R package: PTAk. At the moment the basic scripts I have are based on points and use the R package spatstat, but I would like also to extend to any geometry type. So from all this "a plan" has first to be drawn! ...

R based genetic algorithm for optimization, variable selection and other machine learning and statistical analysis approaches.

R2HTML is a package for R, which includes HTML function and methods to output R objects to HTML. Allow for redirection on the fly. A driver for Sweave allows to parse HTML flat files containing R code and to automatically write the corresponding outputs.

RATH is beyond an open-source alternative to Data Analysis and Visualization tools such as Tableau. It automates your Exploratory Data Analysis workflow with an Augmented Analytic engine by discovering patterns, insights, causals and presents those insights with powerful auto-generated multi-dimensional data visualization.

RDF-DocMan is a document manager based on a Sesame (RDF repository) backend. Documents are stored in the filesystem and their metadata in a Sesame repository. It was developed for porQual web content generator (also in sf.net).

Searches arbitrary text input (logs, etc) for regular expression(s) matching, and then executes arbitrary SQL statement(s) with matched substrings used as parameters. Offers daemon, incremental and transactional features.

RElib is a shared library to allow programmers to have a C++ interface to deal, manage, and operate with Finite Automatons (Deterministic and Non Deterministic), and Regular Expressions to create programs for their needs, as for example to analyze a text

RILA is a machine learning software for relational data. It is able to find frequent patterns in a set of connected tables stored in relational database management systems.

RISO: distributed, heterogeneous Bayesian belief networks. Belief network: a probability model defined on an acyclic directed graph; distributed: nodes can be on different hosts; and heterogeneous: allowing different types of conditional distributions.

RITCode is an analysis tool for captured eye tracker video files. It allows the scientist to analyze eye movements and characteristics of the scene. It has been created by the Rochester Institute Of Technology Visual Perception Lab.

The ROSE reasoner is used to for reasoning with RDFS ontologies and currently supports the RDF, RDFS and eRDFS entailment regimes. An online demo of the RDFS Reasoner can be found here: http://tools.deri.org/rdfs-reasoner/

RRDPlanner project consists in a set of tools to help in capacity planning from data collected in Round Robin Database files (from PNP4Nagios, Cacti or other polling softwares).

RSMeter is a package for interfacing to the RadioShack/Metex 22-168A series of serial-connected multimeters. Currently, it includes an ncurses interface and a script to graph readings. Support for other meters is planned in the future, with an API.

This Tool allows you to analyze logfiles create in RaceChrono (http://www.racechrono.com) on your computer. Top speed, distance, acceleration, speed graph, altitude profile, export to GPX and more features are coming in the next versions.

Radoteur is a basic word generator ; from a list of words, it generates word which \"feel\" the same.

Random Projection Trees is a recursive space partitioning datastructure which can automatically adapt to the underlying (linear or non-linear) structure in data. It has strong theoretical guarantees on rates of convergence and works well in practice.

Recon-Calc is a source code feature location tool based on the Software Reconnaissance technique. It allows you to name features of your system and then, based on coverage profiles gathered, you can find where they are implemented in the source code.

The goal of the project is the creation of new mechanisms for supporting users in the evaluation of Web content credibility and improvement of the quality of Web content credibility evaluation. Our society increasingly relies on the vast amount of information available on the Internet. As a consequence, the issue of judging or evaluating the credibility of this information becomes of crucial importance. Thus, algorithms and mechanisms for the assessment of credibility of Web content can have a great, positive social impact. Dataset from our mTurk studies is now available for public use! Our dataset contains 15750 evaluations of 5543 pages from 2041 participants with some additional information about website characteristics and basic demographic features of users. If You would like to gain access to this data-set or learn more about data structure please contact our administrator (konrad@pjwstk.edu.pl) stating Your name, academic degree and university affiliation.
