The sensitivity calculations show that sensitivity decreases with depth, corresponding to the limit of the sounding frequency.
Figure 5a shows the resultant model sensitivity, which decreases with depth, corresponding to the limit of the sounding frequency.
Littoral zone (the western part of Douala and Edea localities) presents a deep lineament trending NW SE corresponding to the limit of the Douala sedimentary basin.
Furthermore, it is observed from Fig. 5 that the zero-to-zero distances of the main peaks of all objective functions are found to be identical, i.e., with the duration of 2 ns, corresponding to the limit of the intrinsic delay resolution set by 1/B with B=500 MHz being the bandwidth of the transmitted signal.
The strength corresponding to the limit of proportionality (LOP) can be obtained by using the following equation: f_{text{fct,L}} = frac{{3.F_{L}.l}}{{2.b.h_{sp}^{2} }}({text{Mpa}}) (1 where, l (500 mm), b (150 mm) and h sp (125 mm) are the span of the specimen, width and distance between the tip of the notch and the top of the specimen, respectively.
For statistical purposes, the value corresponding to the limit of detection of assays was used for undetectable concentrations.
The duration of past exposure corresponding to the limit of 1 million fibers/g of dry tissue was 1 to 2 days in spraying, 3 to 10 days at the production plant and 1 to 4 months in insulation work.
The influence of τmix on the size of NPs plateaued beyond a certain Re, suggesting that these NPs had reached the size corresponding to the limit of rapid mixing.
Be2b specimen came from the Kanchanaburi locality (Table 1, Figure 1), North to the Isthmus of Kra corresponding to the limit of the peninsular Thailand whereas the specimens of the Be2b group came from the Northern Thailand (Loei and Nan provinces, Figure 1) and Northern Lao PDR (Luang Prabang province, Figure 1).
