what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help

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,

What kind of faults ? Like node faults or like intrusion detection ?

Saurabh Mittal

Dear Sir

I want to detect faults occuring due to failure of nodes due to depletion oof energy. The node can be cluster node or it can be cluster head.

Also if a cluster head gets dead, dynamic clustering should recover the network by selecting a new cluster head from the nodes available within the cluster.

Any idea how to detect node level faults in WSN using TCL code and mannasim???

Sri Lekha

Some of the fault detection papers..

@Sri Lekha

I have already read these papers.

Can you please help me to know from where I have to start in ns2 for the abovesaid target.

Rite now what I have learned till now is using mannasim framework for simulating WSN and understood the layout of .tr file generated by TCL files of mannasim.

I dont know whether m going in rite direction or not?

I dont know how I'll be able to detect faults in WSN in an energy efficient manner?

Can you please help to clear my doubts...........

Roshan Chulyada

There should be way to detect failures in node and I have did failure detection in wsn using zigBee nodes but with my own designed software architecture. So, I think you are in right direction.
