CKAN is a powerful data management system that makes data accessible – by providing tools to streamline publishing, sharing, finding and using data. CKAN is aimed at data publishers (national and regional governments, companies and organizations) wanting to make their data open and available.
Appunta is a Framework for the Android platform that allows us not only to easily show geopositional information to the user, but also to create new ways of showing this information or modifying the existing ones.
Basically, you have a set of POI (Points Of Interest) located in a map (thus, with a latitude, longitude, and optionally, an altitude), and you need to show these POI and their related information to the user.
Appunta allows you, out of the box, to represent this information in two different ways, a radar or an augmented reality view. But, you can modify these components to show data in other ways or create new ways of visualizing this information.
Appunta is Open Source and anybody can freely use it. So, what are you waiting for?
SNAPP is a software tool that allows users to visualize the network of interactions resulting from discussion forum posts and replies. The network visualisations of forum interactions provide an opportunity for teachers to rapidly identify patterns of user behaviour – at any stage of course progression. SNAPP has been developed to extract all user interactions from various commercial and open source learning management systems (LMS) such as BlackBoard (including the former WebCT), and Moodle. SNAPP is compatible for both Mac and PC users and operates in Internet Explorer, Firefox and Safari.
OpenDX is a uniquely powerful, full-featured software package for the visualization of scientific, engineering and analytical data: Its open system design is built on a standard interface environments. And its sophisticated data model provides users with great flexibility in creating visualizations.
Katta is a scalable, failure tolerant, distributed, data storage for real time access.
Katta serves large, replicated, indices as shards to serve high loads and very large data sets. These indices can be of different type. Currently implementations are available for Lucene and Hadoop mapfiles.
* Makes serving large or high load indices easy
* Serves very large Lucene or Hadoop Mapfile indices as index shards on many servers
* Replicate shards on different servers for performance and fault-tolerance
* Supports pluggable network topologies
* Master fail-over
* Fast, lightweight, easy to integrate
* Plays well with Hadoop clusters
* Apache Version 2 License
visual guide to Circos A visual guide to Circos (Circos - an information aesthetic for comparative genomics) presents some of the capabilities of Circos and illustrates its application in the field of comparative genomics and genome visualization.
This document describes the implementation of a DAQ model. It provides a number of tools to develop a data acquisition system.
To facilitate comunication between different objects, DAQ++ implements a very simple Observer model, in which some of the DAQ++ objects are defined as DAQpp::Observables and some as DAQpp::Observers. Observers subscribe to the messages defined in the Observables and are notified whenever a change occurs.
The basis of the system is the DAQpp::Module object. It represents a detector or DAQ unit. As such, it implements the basic DAQ commands to get ready, start or stop the DAQ, retreive the data, etc.
