Ah great thanks that's the way I approached it. The next thing they ask is very vague... they ask the probability a woman has hiv if the result is positive? No where else in the question do they say women are any more likely than men so I assume the answer to be another condional probability...

Hi everone, Really stuck on this one, if anyone has any suggestions I would be more than greatful! Problem: A HIV test detects at 90% accuracy It falsly detects people as positive without HIV at 2% and it is estimated that 50% of the tested patients have HIV I need to work out the...

Hi everyone, When a guitar string is played its motion of displacement can be considered in two planes horizontal and vertically. With consideration of the nut and bridge of a guitar (ends) I've been told their their terminating conditions be different? How does the motion cause a...

Alright mate ur propably right, I am only doing this is a hobby! but thanks

Im actually investiging the body resonance of acoustic guitars by recording its body response. I have generated an algorithm based on the physics of a string and have had promising results, like you said to get the unique timbre of the instrument is the challenging part. I am looking to use the...

Yeah its a guitar string model I’m after, in particular i want to model the frictional causes somebody plucking a string with their fingers opposed to a 'clean' strike with a plectrum.

Hi everyone, Regarding the physics of a guitar sting- I don’t know if this is possible! But does anyone have any idea how I could cause a string to be dampened, and then gradually fade off? - I want to replicate the finger plucking effect of a guitar string.

Thanks for the help this definitely gives me something to get going with cheers

Thanks for the reply, do you have any idea of the appopriate equations I should use to create my algorithm? I've now just begun to look into sampled traveling waves as a place to start... hopefully it will lead to something

Hi everybody I’m currently making/coding my own guitar synthesiser and I are interested in creating a 'bend' playing effect. By modifying the tension of guitar strings I presume I will be able to change the rate in which sounds travels in these strings. From playing guitar myself I thought...
