  • Preview Turbogears Tutorial
    TurboGears About the Tutorial TurboGears is a Python web application framework, which consists of many modules. It is designed around the MVC architecture that are similar to Ruby on Rails or Struts. TurboGears are designed to make rapid web application development in Python easier and more supportable. TurboGears is a web application framework written in Python. TurboGears follows the Model-View-Controller paradigm as do most modern web frameworks like Rails, Django, Struts, etc. This is an elementary tutorial that covers all the basics of TurboGears. Audience This tutorial has been designed for all those readers who want to learn the basics of TurboGears. It is especially going to be useful for all those Web developers who are required to simplify complex problems and create single database backed webpages. Prerequisites We assume the readers of this tutorial have a basic knowledge of web application frameworks. It will be an added advantage if the readers have hands-on experience of Python programming language. In addition, it is going to also help if the readers have an elementary knowledge of Ruby-on-Rails and Struts. Disclaimer & Copyright Copyright 2016 by Tutorials Point (I) Pvt. Ltd.

An online analytical processing multi-dimensional data warehouse for malaria data. Database (2017) Vol. 2017: article ID bax073; doi:10.1093/database/bax073 Received 15 July 2016; Revised 21 August 2017; Accepted 22 August 2017 Abstract Malaria is a vector-borne disease that contributes substantially to the global burden of morbidity and mortality. The management of malaria-related data from heterogeneous, autonomous, and distributed data sources poses unique challenges and requirements. Although online data storage systems exist that address specific malaria-related issues, a globally integrated online resource to address different aspects of the disease does not exist. In this article, we describe the design, implementation, and applications of a multi- dimensional, online analytical processing data warehouse, named the VecNet Data Warehouse (VecNet-DW). It is the first online, globally-integrated platform that provides efficient search, retrieval and visualization of historical, predictive, and static malaria- related data, organized in data marts.

The TurboGears Toolbox provides tools for creating and charting your database model, adding data to your database with a web based GUI while you are still in development, debugging system problems, browsing all of the installed widgets, and internationalizing your application. 19.1 Toolbox Overview The TurboGears Toolbox is started with the tg-admin toolbox command. Your browser should automatically pop up when you start the Toolbox, but if it doesn’t you should still be able to browse to http://localhost:7654, where you’ll see a web page with links for each of the tools in the toolbox (as seen in Figure 19.1). FIGURE 19.1 The TurboGears Toolbox home page Each of the components in the Toolbox is also a TurboGears application, so you can also look at them as examples of how TurboGears applications are built. 372 226Ramm_ch19i_indd.indd6Ramm_ch19i_indd.indd 337272 110/17/060/17/06 111:50:431:50:43 AAMM 19.2 ModelDesigner 373 Because there isn’t anything in TurboGears that can’t be done in code or from the command line, the use of the Toolbox is entirely optional.

  • Managing and Displaying User Track Data with Python
    Managing and displaying user track data with Python Walter Aprile Emanuele Ruffaldi Antonio Frisoli Massimo Bergamasco [email protected] [email protected] [email protected] [email protected] Scuola Superiore Sant'Anna, Laboratorio PERCRO Viale R. Piaggio 34, 56025 Pontedera (PI), Italy +39 050 883057 Abstract: User studies that feature user movement in the real world or in simulated environment generate datasets, usually in the form of logfiles, that need to be stored, summarized, processed and represented. Datasets must additionally include metadata that accounts for experimental conditions. We have developed a class that produces graphical displays of user travels over a regularly-spaced grid, and a set of web-controllable database management tools that allow incremental data exploration as the user experiments progress. Making sense of user movement and user commands In our research work at the PERceptual RObotics (PERCRO) laboratory of Scuola Superiore Sant'Anna we frequently work with data that describes the movement of users when performing tasks. This data can describe various types of phenomena such as: 1- end effector user-controlled movement of haptic interfaces: a user holds a haptic interface such as a force feedback joystick or a GRAB interface (Avizzano et al., 2003), and we are interested in the movement of the point where the users' fingers contact the physical interface. 2- user navigation through a virtual environment 3- hand and head motion acquired through various optical tracking techniques 4- multi-track movement
