Profitable Research?

Let me initiate a debate with a controversy about the role of Science and scientists in modern societies.The evaluation of Science, and its funding system, are nowadays very dependant on the assumption that good science should be profitable. Scientific research is beneficial for society, because it provides two valuable outputs:- New technologies (output of applied research).- Better education level (output of basic research).The modern vision of Science considers only the first output, and…See More

What´s up Francois!
More than a piece of code, it´s a simulation of an EEG adquisition device performed by simulink blocks (with some parameters of course), without noise, and have de advantage that you can add your pattern recognition code, and run a full simulation of it. The only problem is that you will need a very powerfull computer, because simulink is a very heavy tool for computer resources. You can run a BCI with patient connected almost at real time, only if your code is not too long. For example, I can work with 2 channels with 200 Hz sampling speed, and run patter recogniton arlgorithm (with 4th. level operations) and run my simulation of pointer movement in a intel pentium dual core at 1.6 Ghz, 1Mb caché, 1GB of ram, and leaving windows only with the essential services. Tou will need a little circuit, an audio plug (that you use to connect your headset to the computer audio input), and a Matlab 2007a release or superior. Please write me to see how we can share this info and data. Thans a lot and good day!!!
