These special SMT components are placed on the PCB using a machine which literally grabs the components one at a time and places them on the board using a guided positioning system or in some older machines I've seen (like the one picture at right) by moving the PCB itself around, with the feed mechanism stationary.
Let's break this down and look at each component one step at a time.
Similarly to the one-factor-at-a-time (OAT) methods for parameter sensitivity, this method varies the model structure components one at a time and evaluates the change in sensitivity towards the output variables.
For this, we need to understand the wiring of the circuit and manipulate its key components, one at a time.
Component-based design improves productivity by concentrating development efforts on one component at a time without having to worry about a change having an application-wide effect.
Response surface methodology was applied for the critical medium components (initial pH, mannitol, yeast extract and calcium chloride) identified earlier by one-factor-at-a-time approach.
Optimization of the medium components, including ethanol, methanol, phytate, olive oil and surfactant was carried out using "one-factor-at-a-time" and central composite design (CCD) methods.
We evaluated the relative importance of each of the components of rMED on type 2 diabetes risk by subtracting one component at a time from the original score, as previously reported (20).
To evaluate whether the protective effect observed in this analysis was predominantly because of a specific component of the score, we performed sensitivity analyses eliminating one component at a time from the score, as well as alcohol and an another component at a time.
In contrast to QDOCK, the IQP framework can simultaneously fit all the components into the assembly, while QDOCK can only fit one component at a time.
