To conclude the analysis, the physical-based reduced order, and neural network reduced order models of the engine are replaced in the flight performance model to evaluate their impact on the integrated model. A high-level metric as the specific air range (SAR) was selected to compare...
Similar results of narrowed pulse pressure were observed in ME/CFS during a 10-min orthostatic stressor (NASA lean test) [76], and lower SBP with higher vagal tone were associated with higher risk of PEM [77]. Vascular dysregulation is increasingly attributed to hypoperfusion in ME/CFS [78]...
A two-segment linear regression model provides a first-order representation of the GPP responses to SM and VPD. A significant break in the slope would indicate that there is a change-point for SM or VPD above which GPP would respond to SM or VPD differently (Supplementary Fig. 1)31,57. ...
A key element of the RAW design is to identify the level of information (Table1) to be provided by the automation to the human when initiating the communication. Note that we only model one human stakeholder in this case, the ATCOs working directly together with the automation. Over time, ...
Reduced Order Models for simulation speed-up applied to a regional aircraft turboprop and its integration into a flight performance model. Motivations If you are in the system simulation business, I’m sure that at a given point in time you have been confronted with unsatisfactory run-time per...
In general, spatial data have a measurement-error component, which we model, and we use restricted maximum likelihood to estimate the SRE model covariance parameters; its required computational time is only the order of the size of the dataset. Our implementation is demonstrated using mean usual ...
liquid hydrogen container; variable density multi-layer insulation; reduced-order surrogate model optimization1. Introduction Liquid hydrogen (LH2) is usually stored and transported at 20 K under ambient pressure. The boil off of LH2 caused by heat leakage leads to a significant increase in the ...
