The Hopelessness Scale [ 2] is a 20 item self-report instrument designed to assess pessimistic expectations.
Single-sided welds are of particular interest, however, current design codes take a pessimistic view of their fatigue performance.
Given the variety and multiplicity of fault types, to simplify the design process, the system algorithm design often focuses on specific fault types, resulting in either over-optimistic (all fault permanent) or over-pessimistic (all faults malicious) dependable system designs.
Based on first- and second-order models, this is shown to produce a design procedure that is pessimistic (i.e., safe) in the main and to a practically acceptable degree.
The Optimism-Pessimism Scale (OPS), originally developed by Dember et al. [ 21], was designed to measure optimistic and pessimistic traits.
This leads to overly pessimistic performance analysis results, and thus to expensive system designs with considerable performance reserves.
Two order sets (dominating set and dominated set generated by order relation) and three risk strategies (optimistic strategy, equable strategy, pessimistic strategy) are induced to construct the model and design the algorithm of ordered three-way decisions.
Since Lord Howe's authority was, by design, extremely limited, the Congressional delegation was pessimistic about the meeting's outcome.
A third, more pessimistic argument, however, might be this: "reaction" messengers are trying to design an experience that doesn't actually fulfill a need people feel they have.
For this purpose, a model based on fuzzy axiomatic design (FAD) is presented, wherein each evaluation has both optimistic and pessimistic fuzzy scores, as the fuzzy evaluations themselves have risks.
