However, despite decade-long research, it is not clear how the shape factor can be calcu- lated. Even for the simplest geometry (rectangular cuboid matrix blocks), many different formulas have been proposed in the literature. The simplified schematic of the dual-poros- ity model and the ...

aIn contrast to the experiments reported in the literature [13], the shape of the frame was chosen in order to represent a rectangular tunnel. Hereby, only the upper triangle of the cross-section was considered. 与在文学报告的实验对比 (13),框架的形状被选择为了代表一个长方形隧道。 特此,横断...
A GA is proposed for solving the problem. Osman et al. (2003) employ a GA for planning the layout of a site of arbitrary shape modelled as a grid. Rectangular facilities of different sizes have to be placed. Easa and Hossain (2008) formulate a mathematical program for the problem to ...
The shape factor for a typical W-shape (W30 × 90), shown in Figures 8.22e and 8.22f, can be determined in the same manner, abstracting from the complexities of the actual shape by considering only perfectly rectangular flange and web areas. Using the dimensions shown, and performing the ...
31. The theory developed in the last section has pointed out several factors that contribute to the overall SHG signals. The calculation results on the contribution from the following physical factors: (a) The amplitude of FW mode jA0j; (b) the spatial overlap factor jJj; (c) the FW-SHW...
Second-harmonic generation (SHG) from periodic arrays of subwavelength rectangular air hole with various aspect ratios perforated in gold thin films can get resonantly enhanced for some specific geometric shapes. Here we clarify the physical origin of th
section with a pair of movable line markers defining the horizontal boundaries and another pair of movable line markers defining the vertical boundaries, means for moving each pair of line markers to vary the distance therebetween to obtain the rectangular area of desired shape and cross-section. ...
For food and certain other products, an important factor in 2-D shape measurement is the deviation relative to a standard template. Maximum deviations are important because of the need to fit the product into a standard pack. Another useful measure is the area of overflow or underfill relative...
This is because when the size of an image increased, the size of the rectangular bounding box also increased at the same rate. Each geometric shape was noted to exhibit its own Extent value; the values for a triangle, rectangle, pentagon, hexagon and circle are 0.525 ± 0.003, 1....
