True RMS provides a more correct value that is proportional to the square root of the average of the square of the curve, and not to the average of the absolute value. For any given waveform , the ratio of these two averages is constant and, as most measurements are made on what are (nominally) sine waves, the correction factor assumes this ...
A reconfigurable manufacturing system (RMS) is a system invented in 1998 that is designed for the outset of rapid change in its structure, as well as its hardware and software components, in order to quickly adjust its production capacity and functionality within a part family in response to sudden market changes or intrinsic system change.

HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

DSTRE – drill-stem test report; DSTSM – drill-stem test summary report; DSTW – drill-stem test job report/works; DSU – drill spacing unit; DSV – diving support vessel or drilling supervisor; DTI – Department of Trade and Industry (UK) (obsolete; superseded by dBERR, which was then superseded by DECC) DTPB – CNT true vertical-depth ...
The disadvantage is that the voltage output is much lower – the average of an AC half-cycle rather than the peak; this is about 90% of the RMS voltage versus times the RMS voltage (unloaded) for a capacitor input filter. Offsetting this is superior voltage regulation and higher available current, which reduce peak voltage and ripple current ...
RMS 2011 was released in May 2011. RMS 2011 included more new features than any previous RMS version and provided modellers with enhancements to the seismic architecture to allow direct reference between the reservoir models and the 3D and 4D seismic data that the interpretation and modelling is based on. Key highlights of RMS 2011 included new ...
