Hi Max, For all of us it is perfect to have the skype call tomorrow, 25th, at 18.00pm as we proposed. So, as you don't have problems with this time either, we will talk tomorrow. regards Nora

Hi All, Last week we were planning with Nacho and Nora to have a meeting today. maybe you were looking for me but I just switched on the BWN skype account. Do you still want to have the call? Do you prefer to move it to another day, say, tomorrow at 12:00 (Atlanta time)? Please, let me know. Best, Max

Counting particle noise

hi all, There is attached a document where we see that the particle noise power is inversely proportional to the receiver radius. In the previous mail, Max you commented that meausured fluctuations can be cut down taking as a measure the average value within a time interval smaller than the correlation time, and you said this correlation time is equal to the radius of the receiver squared and divided by the diffusion coefficient, could you explain something else about how you find this value? Regards

Parameter list

Hi all again, There is attached an excel file where you can find a list of parameters we use in the simulations, such as dimension space, particle radius, Coefficient diffusion and so on. Some of them we are not sure if they are realistic or not. If somebody has sources where we can find the values for that figures or any comment could you add it the document and sent it back? Thanks Nora

Simulator results 2

Hi all, We have been working lately on the addition of some inertia to the particles, in the attached file you can see some preliminary results. We apply in each time step a mean displacement to each particle following the rules of brownian motion as well as keeping the previous velocity multiplied by a inertia factor, this way the particle movement stops being pure random. Does it has sense for you? x(t)=(Inertia factor)*(v(t)*timestep) + (Brownian Motion) Regards
