Digital Synthesis

My intention in this article is to collect in an only document the ideas practical central offices and relative methods to waveshaping that I have accumulated throughout last the two years having explored the subject. As it is a compendium of some types of materials, the presentation style varies between tutorial and technician, and the orientation varies between practical and theoretical. In general, I tried to place the practical sections and tutorial before the technician and theoreticians. However, so that the ideas in the article can of course be developed, 0ccasionally I found necessary to move away to me from this ideal. To help those readers who can desire to omit the tangential quarrels, the headings of the sections that contain more or less central or especially useful material are marked with punhais. Waveshaping continues to be explored since the moment where the basic project of this article if became fixture. It in such a way has continuous developments in theory as in practical, also some very interesting applications in the simulation of rope timbres similar to the voice. Unhappyly, this research is very recent to be enclosed here, and will have that to be presented at a posterior moment. We wait that this exposition is of some utility for that they desire to lead new inquiries of waveshaping.

Digital Invitations

Technology places of side the invitations of paper and the space for the digital invitations. Beyond modern, also it collaborates with the environment. A made recent survey on the use of the Internet in Brazil identified that 54% of the Brazilian population have access Internet, this represents about 81,3 million people. Many of the occured changes due to amount of users who are using the Internet currently can be seen in simple situations, as the search for information, or even though to follow seriados soap operas and. Many people who already used the Internet as work tool had started to use it as informative source of the daily news by means of the periodical reading and sites, thing that before exclusively was made in units periodical printed matters. Tools that facilitate day-by-day had more started to be each time looked by the users, therefore, who does not want to decide the problems with more agility. Thinking about this, the entrepreneur Robert Oliveira decided to innovate and developed a site that offers invitations digital.

In, the person can make the invitation of its party, either of anniversary, marriage, infantile, formation or even though for corporative parties. ' ' Through diverse models of invitation, the user chooses one that has more to have with the subject of the party, the invitation is available in the Internet where the guests have access to all the information on the party, (photos, map of localization, list of gifts, etc.) this allows that the host interacts and shares the preparativeses of the party leaving the guests each time more anxious and livened up ' ' , Robert says. In this space the guests still can leave depositions for the host. One of the tools most interesting for the host is the field where the guest can confirm the presence. Robert still affirms ' ' in the age of the technological evolution, the digital invitation turned a fever between the users, with the possibility even though to have access Internet for mobile devices, the young, adores to interact and to see the new features postadas for friends to share them in its social nets, something until then, impossible to be made through the traditional invitations in papel' '. Social responsibility Beyond modern, the digital invitation supports the environment. After all, it saves paper and the more paper is produced, more trees is cut, more water is spends in the production process and more space in lixos and aterros is busy. Data of the Institute Akatu, a not governmental organization without lucrative ends that work for the awareness and mobilization of the society for Conscientious Consumo, for each ton of virgin paper, twelve trees are knocked down. 540 liters are necessary to produce one kilo.
