- This video demonstrates "How to write a equation in origin, fit the data and calculate the parameters?". In the present tutorial, i have taken the experimental data as variation of dc conductivity with temperature i.e., Arrhenius diagram to calculate the activation energy.
Woooow, what a great explanation.
I struggled a lot to do my fitting, until I found your video. Thanks man .. keep it up.
Glad it helped!
Thank you sir
I got one modified Gompertz equation for calculation of Minimum inhibitory concentration of bacteria which is 𝑓(𝑦)=𝐴+𝐶ⅇ^(−ⅇ^𝐵(𝑥−𝑀) ), Do you have any suggestion how to fit this equation in origin, Reference of given equation is: Determining the Minimum Inhibitory Concentration (MIC) of Different Antibiotics Against a Drug-Resistant Bacteria
it is an amazing explanation, please explain how to fit experimental data with a model, for example, fitting of Friedman method with the TGA curve in the Isoconversional method for the calculation of Activation energy and pre-exponential factor
Okay. Let me go through the literature and I will make a video on it.
Could you please help me to do a fitting line please? I have tried to do it but still have a problem
thanks
You're welcome!
Hi, I need a little help.
I have a data point value of theta vs time and the resultant graph is periodic in nature (from experiment)
But, I want to find an equation approximately representing that graph.
So , my question is can I get an equation of graph in the software if I have data values ?
Please assist me .
Thank you
Sure, you can fit the data with a periodic function or at least Fourier series or a polynomial series. Mail me the data in Excel with clear specifications through email around Wednesday of next week. I will do it.
I am facing a problem in fitting the equation H(T)=H(0)[1-T/Tb]^0.5. Here T and H(T) are known and I need to calculate Tb. Every time I fit, I get the value as 1. help me out.
Thank you for your question. I would suggest that 1. Keep notations one character 2. Simulate the curve using initial value 3. Make sure to use brackets. This is a very easy equation and if you do not succeed still, mail me the data and i will take a look
why you have taken the value 0.4343 and 8.314 in the main functipon. kindly reply. can we use the same method to determine diode parameters?
These are conversion factor for universal gas constant and conversion from log to ln.
Sir, How do we fit complex numbers into the data, I am trying to fit this Debye equation
E~ = E∞ + (deltaE1/(1+jwT1))+(deltaE2/(1+jwT2))+(deltaE3/(1+jwT3))
Here j is an imaginary number, (a+jb), please tell me how do I fit this j into the origin, sir.
For a complex function you need to find the real part of the complex function and also the imaginary part. You can fit them separately
Hello sir
I am finding problem in fitting birch murnaghan third order equation in origin in pressure volume data. Problem is that when I fit data taking pressure on x-axis and volume on y-axis the fitting does not converge but in vice versa situation that is - volume on x-axis and pressure on y- y-axis fitting runs finely. But i need it reversly
This is a straight mathematical expression. Please put the code in "expression" format. Note: put brackets properly. If possible kindly post your code. Let me check.
Thanks a lot sir for your reply.. Now the problem has been solved using different software
Hello Sir.. Can i have your email Id
