The physic of the real world can be formulated into mathematical form using differential equations. Differential equation and systems of differential equations are the natural language trough we can describe any real devices like electronic circuit, automatic controls, elettro-magnetic wave emission or any other engineering problems. The purpose of OpenDDPT project is to build a software that can aids people to build automatically these control devices. The strategy used by this software is based on the concept that differential equations generally are parameters dependent so we can found optimal control parameters using an optimization template. The optimization tool-box used by OpenDDPT is an innovative non-convex second-order method that replaces the hessian structure (the hessian matrix has heavy memory storage and an expensive computational-cost) with directional-derivatives , reducing the second order information computational cost of one order without approximation.Control's local informations (i.e. gradient and it's directional derivate) are found trough an extended form of the back-propagation rule used for neural-network and that new extended form can perform not only weighted-sum and sigmoidal saturations but also multiplication ,addition, time-delay and any non-linearity and it can be used as a generic expression for realizing any non linear discrete time control device.

SNV Timer is an easy-to-use desktop schedule program which includes multiple circuit countdown timers and alarms with a lot of scheduled tasks and greatly custom skins. You can set each alarm or timer to display a multi custom message, open a picture or a video clip, play a MP3, WAV, MID and other audio files (including their random selection from a specified folder), run an application or screen saver, shut down your PC, dial a phone number, open a document or a web page, and much more.
You can set various intervals for your alarms and timers: daily, on different days of the week, every 1...99999 seconds/minutes/hours/days, weekly, monthly, yearly.
Are you tired of standard Windows messages? No problem. Make your own message boxes! You can set a background image (including its random selection from a specified folder), color, font, border, size, shape, gradual appearing/disappearing, symbol-by-symbol print and other properties of your messages.
New! Are you tired of typing a trigger time? No problem. Set the time by simple rotation of hour-hand with mouse!
Do you want to use your voice as alert? No problem. Make your own voice alerts with the embedded voice recorder!
SNV Timer can also be a normal desktop clock. You can customize its background image, color, border, size, shape, title, shadow, tray icon and more.
