The existing works are generally in the form of depth point-to …
Metal-Organic Frameworks (MOFs) are a class of materials that consist of metal ions or clusters connected by organic ligands, and their resulting structure is a three-dimensional porous network with a large surface area and porosity, which can be used for applications such as drug delivery, and tissue engineering (Perry Iv et al., 2009; …
2.4.2. Physical properties. The Archimedes method (ASTM: B962-13) was employed to study the relative density and apparent porosity of sintered dense/porous samples at 1250 °C for 1 h, as detailed in our recent work [32]. 2.4.3. Mechanical and elastic properties. The microhardness of the prepared specimens was assessed in …
Fig. 4, Fig. 5, Fig. 6 clearly show that the predicted porosity follows a similar pattern to the measured porosity and has a nearly same value. The BLSTM model has the lowest prediction errors when compared to the CNN and LSTM models. These findings indicate that the BLSTM model attains the highest degree of precision when forecasting porosity.
Moreover, geotechnical engineering as a branch of civil engineering that deals with the principles of soil and rock mechanics (i.e. porosity, permeability, and …
