Finally, the paper identifies areas where further research efforts are needed.
However, the further research efforts on lowering the IERs are rare.
The flash tank cycle control strategy and refrigerant charge management strategy are worth further research efforts.
However, a prediction of scale factors from simple soil properties was only partly successful and needs further research efforts.
Preliminary investigations have also been carried out and further research efforts are in progress on the fastener service life predictions.
Furthermore, the large variations in the VOR values indicate the need for further research efforts in this area.
Prevention of such corrosion requires further research efforts, perhaps focused on a new design-for-recycling approach of LIBs.
Further research efforts should comprise testing of the method in more locations and analyzing the performance of more widely applicable ways of deriving the initial parameters.
Finally, to stimulate further research efforts, other important outlooks including computational issues, multivariate optimal design and measures of risk alternative to the standard expected loss minimisation are discussed.
Although an extensive literature has been devoted to mine and model mobility features, forecasting where, when and whom people will encounter/colocate still deserve further research efforts.
The results of this work inspire further research efforts to use 3D photothermal structures to break through the energy efficiency limit of 2D photothermal materials.
