      • Extensions

        The Joomla! content management system lets you create webpages of various types using extensions. There are 5 basic types of extensions: components, modules, templates, languages, and plugins. Your website includes the extensions you need to create a basic website in English, but thousands of additional extensions of all types are available. The Joomla! Extensions Directory is the largest directory of Joomla extensions.

        • Components

          Component ImageComponents are larger extensions that produce the major content for your site. Each component has one or more "views" that control how content is displayed. In the Joomla administrator there are additional extensions such as Menus, Redirection, and the extension managers.

        • Modules

          Media ImageModules are small blocks of content that can be displayed in positions on a web page. The menus on this site are displayed in modules. The core of Joomla! includes 24 separate modules ranging from login to search to random images. Each module has a name that starts mod_ but when it displays it has a title. In the descriptions in this section, the titles are the same as the names.

            Content modules display article and other information from the content component.

            These modules display information from components other than content and user. These include weblinks, news feeds and the media manager.

          • Navigation Modules

            Navigation modules help your visitors move through your site and find what they need.

            Menus provide your site with structure and help your visitors navigate your site.  Although they are all based on the same menu module, the variety of ways menus are used in the sample data show how flexible this module is.

            A menu can range from extremely simple (for example the top menu or the menu for the Australian Parks sample site) to extremely complex (for example the About Joomla! menu with its many levels). They can also be used for other types of presentation such as the site map linked from the "This Site" menu.

            Breadcrumbs provide users with information about where they are in a site.

        • Templates

          Media ImageTemplates give your site its look and feel. They determine layout, colours, typefaces, graphics and other aspects of design that make your site unique. Your installation of Joomla comes prepackaged with three front end templates and two backend templates. Help

        • Plugins

          Plugin ImagePlugins are small task oriented extensions that enhance the Joomla! framework. Some are associated with particular extensions and others, such as editors, are used across all of Joomla. Most beginning users do not need to change any of the plugins that install with Joomla.

        These are my photos from parks I have visited (I didn't take them, they are all from Wikimedia Commons).

        This shows you how to make a simple image gallery using articles in com_content.

        In each article put a thumbnail image before a "readmore" and the full size image after it. Set the article to Show Intro Text: Hide.

      • Growers

        We search the whole countryside for the best fruit growers.

        You can let each supplier have a page that he or she can edit. To see this in action you will need to create a user who is in the suppliers group.  

        Create one page in the growers category for that user and make that supplier the author of the page. That user will be able to edit his or her page.

        This illustrates the use of the Edit Own permission.

    FIRST MULTIFLOW CONFERENCE ON:

    THE TURBULENT/NON-TURBULENT INTERFACE


     
     

    School of Aeronautics, Madrid, Spain 25-26 October 2012

     

    Objectives

    The Multiflow Conference on Turbulent-Nonturbulent Interfaces has the goal of bringing together researchers to expose and summarize the newest problems and findings relating with the  turbulent entrainment and it's link with the geometry and characteristics of the so called turbulent/non-turbulent (T/NT) interface separating the irrotational from the turbulent flow in mixing layers, wakes, jets and boudary layers. It has the objective of uniting researchers so that new directions of investigation and collaborative work can be discerned.

    EUROMECH COLLOQUIUM 517 ON:

    INTERFACES AND INHOMOGENEOUS TURBULENCE


     
     

    University College London, London, 28-30 June 2010

     

    Objectives

    Recent research has shown that a layer of strong shear may act as a barrier for eddies and prevent it from penetrating through that layer. These shear interfaces, because of their persistence, have a major importance on the flow dynamics because of their impact on transport of heat, mass and momentum. Over the past decade, their relevance has been recognized in a variety of different flows. In atmospheric flows the edge of the polar vortex is known to act as a barrier for the transport of ozone depleting gases; in turbulent boundary layers transport is blocked according to the same mechanism. Layers of shear are equally formed in planetary atmospheres (e.g. Jupiter, known as PV staircases), in plasmas (e.g. Tokamaks, Sun), transport barriers play a dominant role for the flow dynamics and explain anomalies observed in energy spectra. The aim of this meeting is to bridge these traditional research disciplines and to discuss interfacial processes that occur in diverse areas of fluid mechanics.

    ECCOMAS: CFD 2010

    5th EUROPEAN CONFERENCE ON

    COMPUTATIONAL FLUID DYNAMICS

     

     
     

    Lisbon, Portugal, 14-17 of June, 2010

     

    Background

    The European Community on Computational Methods in Applied Sciences (ECCOMAS) announces the organization of the Fifth European Conference on Computational Fluid Dynamics (ECCOMAS CFD 2010) to be held in Lisbon on JUNE 14th - 17th June 2010. Previous editions of the very successful ECCOMAS CFD conferences were held in Stuttgart (1994), Athens (1998), Swansea (2001) and Egmond aan Zee (2006). Furthermore, computational fluid dynamics, computational mechanics and related fields have been a major topic at the ECCOMAS congresses held in Brussels (1992), Paris (1996), Barcelona (2000), Jyvaskyla (2004) and Venice (2008). The ECCOMAS CFD2010 conference includes invited plenary and semi-plenary lectures, contributed papers from both Academy and Industry, Minisymposia and Invited Special Technological Sessions.

     

    Objectives

     The goal of the ECCOMAS CFD conferences is to periodically bring together researchers, industrialists and students working in the fields of the science of Computational Fluid Dyamics (CFD). The fields of interest are the applications of mathematical and computational methods and the modelling of different areas: CFD, computational acoustics, computational magnetohydrodynamics (MHD), computational mathematics and numerical methods, optimization and control, computational methods in life sciences and industrial applications. Multidisciplinary applications of these fields to problems encountered in sectors like Aerospace, Car and Ship Industry, Electronics, Energy, Finance, Chemistry, Medicine, Biosciences, and Environmental sciences and Earth sciences are also welcome.

    PROJECTS



     

     

    In order to apply it's academic side, LASEF gets involved in "real-life" engineering projects, where different types of physics are involved. These provide good reality-checks, as sometimes one needs to develop new tools to better tackle a problem. Being involved in these projects is also a way to be in contact with constant source of new and interesting problems that can further be studied in a more academian way.

    LASEF's is currently involved in the projects that follow:

     

     

       

    FC-DISTRICT

     

    "The overall objective of the FC-DISTRICT project is to optimize and implement an innovative energy production and distribution concept for sustainable and energy efficient refurbished or new "energy autonomous" districts, exploiting decentralized co-generation coupled with optimized building and district heat storage and distribution network."

     
      http://fc-district.eu

     

     
       

    DAPHNE

     
     

    "The overall scope of the DAPhNE project is to develop and demonstrate a package of integrated solutions for energy intensive, firing processes (ceramics, cement and glass), based on real time self-adaptive control systems for MW and process control and for tuning micro-wave technologies to the material characteristics, yielding real time information about the process energy consumption as well as the product quality."
