Development of PETSAT requires four interface requirements.
The bus does away with power-consuming termination resistors and instead takes advantage of the wave front reflected from an unterminated bus line to minimize the drive requirements of interface silicon.
The ongoing design of the ITER Ion Cyclotron Heating and Current Drive system (20 MW, 40 55 MHz) is rendered challenging by the wide spectrum of requirements and interface constraints to which it is subject, several of which are conflicting and/or still in a high state of flux.
Given the initial lack of a specific requirement balance, interface designers are required to measure and analyse the value of a user's comfort level.
A systems engineering approach should be applied to specify the requirements and interfaces for the integrated system development environment.
Suitable interface requirements, standards, and protocol are necessary and being developed.
Each of the three UADFs has its own intended methods for developing interface requirements but not all are strong in specialty engineering and environmental requirements.
So the means are there to recall any and all data users require to generate reports of their findings, but no user interface requirements have been compiled or considered as yet.
We then worked with our clinicians to develop the specifications for what the software needed to look like and do if you were in a clinical setting – its user interface requirements".
