What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10? Since, the growth curve from day 2 to 10 won't be like the "Logistic curve" it might not follow logistic...

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,

can you please eloborate I did not understand. I am using Keil IDE for coding STM32. I mean how to interface the Microcontroller with converter. I can generate the PWM signals using STM32 but where should I use them on converter board.

Nikolay Pavlov I got information from the MPS company that MPQ4210 cannot be operated in the parallel connection. We need current sharing for parallel connection that which is not possible with the MPQ4210 board.

Actually, what I wanna do is connecting two converter boards in parallel with same input supply but with different outputs. I have been trying to find a converter board for long but I did not find one in the market. If you had any idea about Bidirectional buck boost converter can you please share me.

Nikolay Pavlov

One can perhaps use much simpler and more common SEPIC converters which can smoothly operate as step up or down, may include current limit. One can just swap the direction of converter by using some MOSFET or even relay (perhaps OPTOMOSFET) based switch.
