Additional tensile characteristics which include modulus of elasticity (E), modulus of resilience (Ur) and ductility (% EL) were obtained using Eq. 2, 3 and 4 respectively.
E=∆σ∆ε (2) Ur=12σyεy (3) %EL=∆LL0×100 (4) In these equations, ∆σ is change in stress, ∆ε is the corresponding change in strain, σy is yield stress, εy is yield strain, ∆L and L0 are the change in length and the initial length of the specimen respectively.

For instance, Albensoeder et al. [25] identified the region of non-uniqueness of multiple flow solutions within various aspect ratios.
Code Validation In order to confirm the proposed solution method, calculations with the FVM are compared with the well-known results by Ghia et al. [10] for one-sided lid-driven cavity and with results by Kuhlmann et al. [23] and Albensoeder et al. [25] for a two-sided lid-driven cavity.
Further, to deepen in the validation, Critical points limiting the region of non-uniqueness of the lower existence Reynolds number for the cat’s eye state as a function of the aspect ratio Г were also assessed with the data of Kuhlmann et al.[23] and Albensoeder et al. [25] in a two-sided lid-driven cavity of antiparallel wall motion as shown in Table 1.

CMEs can be categorised into four groups, depending on the nature of the process of alteration according to Murray et al.
Ambrosi et al. used carbon paste, gold electrodes, and other methods to quantify ofloxacin and other medications.
According to Wu et al. in work GCE was modified using   perfluorosulfonic acid, nitrogen-hybrid graphene (GR), and nano-Cu2O.

Some studies focus on specific parts of the building delivery process: Mahdavi and El-Bellahy [2], for instance, examined the effort and effectiveness of students to assess the thermal, energy and environmental performance of six designs for a school project.
A study performed by Lu et al. [4] examined this curve, and stated that while BIM might bring in some advantages and disadvantages, it is still necessary to learn more about the time distribution in different projects and work styles.
