Thank you, @andrewkirk, for your answer. That was helpful.

I have the following constrained optimization problem corresponding to the maximum likelihood density estimation: $$ \begin{aligned} &\text{maximize} && L(f) \\ &\text{subject to} && f \in H \\ &&& \int_a^b f(x) \mathop{}\!\mathrm{d} x = 1 \\ &&& f(x) \geq 0...

Encoder not powered/measuring anything. Here is the encoder https://www.celeramotion.com/ultra-incoder/ (at the bottom of the page). It transforms the 24 V from the linear power supply to 3.3 V before feeding the sensor electronic circuit.

It is an industrial application. I am investigating intermittent failures of the encoder, and speculating that its power supply is not reliable because of sporadic brownouts and/or voltage spikes possibly affecting the AC line during peak operation of a rotating machine (permanent magnet...

What are the effects of brownouts and power spikes on linear power supplies in particular; e.g., a linear power supply that provides 24 V to an inductive angle encoder? Thanks for any information you could provide.

I was wondering if there is a method to measure the actual total mass of carbon dioxide (CO2) emitted from a diesel engine used with a generator for power generation (https://www.cat.com/en_US/products/new/power-systems/electric-power/diesel-generator-sets/1000028914.html). Infrared CO2 sensors...

Sorry, but I'm not sure I understand your question.

Yes, this is common. The idea is to measure the fuel consumption by subtracting the return fuel flow rate from the supply fuel flow rate, in order to monitor the fuel consumption in general.

I am measuring the volumetric flow rate of a diesel fuel using "Turbines" flow meter, both in the supply and return fuel lines of an industrial diesel engine (https://www.cat.com/en_US/products/new/power-systems/industrial/industrial-diesel-engines/18398034.html – coupled with a generator for...
