Configuration Definition and 268 Threads

Configuration management (CM) is a systems engineering process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.
The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings.

    How to interpret this circuit configuration? (Sensor bridge)

    So, I'm asked to demonstrate the formulas for finding out the voltage labeled here as ΔU, which I'm given in my project document: I think I would be able to make the demonstrations without any outside help, if only I knew how I'm supposed to interpret this circuit branch in the middle. Is it...

    Electronic configuration of transition elements

    I know about quantum numbers and how we do it as 1s,2s,2p,3s,3p,3d etc...but how do I find the number of valence electrons by doing this ? I watched so many videos about this topic and I still don't get it.Possibly because I am trying to learn the portions before even it is taught at school.Can...

    What happens if an atom's electron configuration remains unstable?

    What happens if an atom's electronic configuration remains unstable? So we know atoms react with each other to share or transfer electrons, causing them to bond. It's in their nature to do so; if they do not, they'll remain unstable (apart from some Noble gases which are already stable). What is...

    Why does the Darlington configuration work the way it does?

    I know the Darlington configuration is supposed to sky rocket the beta value of the system, but this is only assuming the pair can handle that current right? It's a silly question but I just wanted to confirm... I have two low current capacity transistors (I_max= 0.2A). so the setup can only...

    Electron Configuration of Filled Valence Electron Orbitals

    Hi! I have understood how elements such as Be and Ca, with fully filled 2s orbitals, are not to be considered "noble" because they still have unfilled p orbitals. But I'm having trouble understanding how these elements participate in chemical reactions without having any unpaired electrons. My...
