    Kalman filter design for impedance measurement data

    Hello, I am trying to implement Kalman fiter to remove some Gaussian white noise. I have succesfully implemented moving average filter but I would like to compare them in Matlab. Lets assume that I have nominal values for model parameters: Re = 917.5; Ri = 629.0; Cm = 3.42e-9;while model is...

    Solve system of three nonliner equations in MATLAB - bioimpedance modelling

    I think that I have three independent equations because I have known |Z|, Real and Imaginary part and Re, Ri and C are unknown. Relationship between |Z| and (Real, Imag) is |Z|=sqrt(Real*Real+Imag*Imag) so I have to have set of solutions (Re, Ri, C) which will satisfy |Z|, Real and Imag but not...

    Solve system of three nonliner equations in MATLAB - bioimpedance modelling

    Hello, I am trying to solve problem of parameter estimation of 2R-1C model of bioimpedance. I have made measurements and I have |Z| and phase angle data in frequency range 10k-100kHZ, so I calculated real and imaginary part. I would like now to estimate parameters of the model: Re, Ri and Cm...

    [SOLVED] Access to the same database from C# and ASP.NET

    Thank you very much for your reply. Can you please be more specific? I have to restart my project or I can change project settings? C# application should have permission to read/write/delete data while ASP.NET should have read-only access. Thanks.

    [SOLVED] Access to the same database from C# and ASP.NET

    I am using Microsoft Visual Studio 2013 Ultimate. I have one C# application connected with WSN to collect and save all sensor readings in database. It is working fine and stable. Later I decided to add ASP.NET application (developed in the same software) so other computers in LAN can access my...

    Adding Y value on different X position (time)

    I have global time, variable DateTime now = DateTime.Now; is global and it is updated on every new results. I will try to explain my problem: 1. I have only the coordinator in network. It has own temperature, RH and light sensor so graphs are started. 2. For example, 5 seconds later the second...
