The Fourier Transform is a powerful tool allowing us to move back and forth between the spatial and frequency domains. Many of our explanations of key aspects of signal processing rely on an understanding of how and why a certain operation is performed in one domain or another. This applet helps students feel comfortable with these explanations, helping to build a strong intuitive grasp of how signals in one domain correspond to signals in the other. Students can load scanlines from common image patterns and see that scanline's Fourier Transform in real-time. For example, they can load the scanline of a standard test image to note how most of the energy is concentrated at low frequencies -- a key to why low-pass filtering doesn't render an image unintelligible.
Adobe Macromedia Flash is everywhere online. From its first version to its most recent 8th iteration, it has had an increasing impact on the web. Now, it is becoming useful for educators. Learning it is an excellent skill to have for online educators. This tutorial will guide students in creating an animated banner using Adobe Macromedia Flash 8, a popular multimedia authoring application. The material is part of the online resources for the textbook Web Design & Development Foundations with XHTML.
OPEN ACCESS REACHING DIVERSE COMMUNITIESVoir le lien : http://www.berlin7.org/The 7th Berlin Open Access Conference will take place at the Panthéon-Sorbonne University in Paris on 2-4 December 2009. As well as taking stock of past activities, the conference will focus on the question of how to get the different communities more actively involved.About the Berlin DeclarationIn 2003, leading European research institutes and the scientific community signed the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities on the Internet. The declaration followed on from the Budapest Open Access Initiative in 2002. In signing the declaration, governments, research institutions, funding agencies, libraries, archives and museums committed themselves to taking concrete steps to promote the Internet as a medium for disseminating global knowledge.Since 2003, the signatories have met annually at international conferences to report on the significant headway made in open access to the results of scientific research.The commitment of French research to Open AccessThe leading research institutes in France have played an active part in the Open Access Initiative from the outset. A Memorandum of Understanding signed by the universities and most of the country’s foremost research organisations strengthened the commitment of the French scientific community to Open Archives. The choice of the Sorbonne as the venue for the 7th Berlin conference is a further indication of this commitment.Berlin 7 is an international showcase, during which France will be able to highlight its efforts in favour of open access to scientific knowledge, as well as the involvement of all the various players. It also provides an opportunity to present the concrete measures taken in this area by French research organisations, in particular through achievements such as the national HAL (Hyper Article on Line) platform.Open access in the realm of French research
