What is the difference between wavelet transform and Hilbert-Huang transform?

If we want to have the frequency vs. time, or frequency content of a signal, we can use wavelet transform or Hilbert-Huang transform. What are the differences and advantages or disadvantages of...

How can I perform a continuous wavelet transform?

I've written a code for continuous wavelet transform using a Cauchy type wavelet function. But the intensity of wavelets aren't true. they are rippling in time. I used multiplication in the...

I have a problem in understanding of EMD algorithm (Empirical Mode Decomposition).

The number of local maximums and minimums of the signal is not equal so I can't sum them. I mean ' h1 =(emax+emin)/2'. And the other problem arises when I try to subtract the signal 'h1' from...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
