The merit of such designs was realised during the First World War when forces recorded information in the trenches using portable typewriters . The conceptual system design is the first stage in the systems design life cycle and an example of the systems definition requirements process is shown in Figure 1 . One of the chair designs was modeled satisfactorily on the second try , with no radical changes from the original concept . Another potential drawback of the changing design is lack of visual unity . A quick glance confirms that the two designs are not identical - the GE capsule has a shallower heat shield and stronger slope on the sides of the capsule . Limiting total attendance serves to keep non-scientists out , since if researchers for whom the conference is designed are turned away due to lack of space , there will be a rationale to limit the number of slots for press , company representatives , or people with AIDS . High level designs are often metaphorical , such as a " network backbone " . Three different counter designs are now in use at the Center , including a low-background instrument that uses a pulse shape discrimination circuit to simultaneously count environmental samples for alpha and beta activities . Design is not merely a scientific question . In the preliminary study , the voussoirs to be designed are still being used in a basic geometric shape , without carving the curves above and below . " We [ at MEJ ] did n't necessarily see an IP connection , but we realized that licensing designs was more profitable and more scalable than design services . The designs are all created around a theme related to the stamp affixed on the cover . Because experimental and quasi-experimental research designs are impractical , many argue for a theory of change approach to assess a CCI . A comparison across designs was made by measuring the beam width . This design is more effective over a wider range of conditions than is possible with either blade alone . ] it is devyded in dyvers parts designed be severall names .
