Concept evaluation

The working level concept evaluates the unattached fraction and the activity median diameter in an indirect way, through the dose conversion factor. This paper will show that in the domestic environment this is mostly inaccurate to estimate the dose. 

The first stage in library production is the design stage wherein we arrive at the concept, evaluate literature precedent, determine the novelty of the proposed scaffolds in regards to our internal compound collection and external patent sources, and viability of the proposed synthetic route. 

For testing, the Mod 2 burner is housed within a heavily walled pressure vessel which also serves as a plenum chamber for the preheated inlet air supply. See Ref. 16 for a description of the test facility. The burner assembly is shown schematically in Figure 2 and is designed to use 100% of the air flow in the combustion process. Thus, air film cooling and air dilution which are normally used in an engine combustor are omitted. In this way, combustion effects from air injection are avoided for the concept evaluation. The cylindrical combustion chamber is water cooled, as are the sonic exhaust nozzle and gas sample probe.

Eor each of these classes, specific relative criteria should be identified and defined in quantitative form. How this should be done is discussed in Section 5.5, Design Concept Evaluation. The determination of evaluation criteria is not a trivial matter, because they reflect our priorities and their selection will have impact on the direction of our search for novel solutions. Eor example, if novelty is important, it should be reflected in a large value of the weights associated with all novelty criteria. 

There is still a lot of research on concept evaluation, for example (Koziolek et al. 2010), but the proposed simple approach is usually sufficient, and improving its performance leads to a significant increase in the complexity and difficulty of the evaluation process.

The test of plant compatibility ensures that the operator is able to complete the required action with the hardware and systems that are in place. This includes ensuring that any action to be taken within the plant by shift personnel can be done so safely under anticipated emergency conditions (e.g. wearing protective equipment in hostile conditions). This may require that some plant systems or areas be modified (e.g. by adding shielding). If the plant does not respond as intended the operator loses confidence in the procedure. This concept evaluates the following ...

The other concepts evaluated were intended to reduce the pressure boimdaty temperatirre by using primary coolant or stagnant gas as a resistance layer. These concepts proved non-viable unless an insulating layer was added, similar to that used in the internally insulated hot leg concept. This would add complexity to the alternative concepts with no advantage over the internally insulated concept, while also decreasing the hot leg area for gas flow which ultimately increases pressure drop and decreases cycle efficiency.
