The mathematical representation of a system domain that has been discretized using variable-size and shape finite cells, and that uses assumed continuous distributions of the dependent variable within each element. It also commonly means the simulation using the foregoing. Free body (FB) Conceptual re...

methodological aids, e.g., cost–benefit analysis (Jeswani et al.2010). There are methods proposed for the use of LCA together with LCC (França et al.2021). Recently, LCC was implemented in the LCA software – openLCA, but focused on environmental Life Cycle Costing, not operational ...
Critical data at various levels will be required to operationalise the framework. First, at the rail transit station level, the required data would include the station’s design details and its connections with other modes of transport. At the mall level, data to support the framework would inc...

To implement the new SCDDA in an operational setting, the online mode of the stochastic simulation is carried out using the following steps: Similar to Q22, the conditional PDF of the CDDA model error is estimated using the K Nearest Neighbours (KNN) resampling approach (Sikorska et al., 201...
The rotors developed for eVTOL vehicles are designed based on two control types: the fixed pitch rpm control or the variable pitch control at constant rpm. Depending on the vehicle architecture and operating conditions, both con- trol types are utilized in various eVTOL models. For exam- ple, ...
The battery pack energy was first introduced as the state variable. The state transition equality became convex but not affine, by replacing the battery SoC with battery pack energy. Then, the non-affine equality constraint was relaxed to a convex inequality constraint. Finally, the battery ...
