This is due to the law of large numbers, which states that the average number of winners will be very small in comparison to the total number of tickets sold. The lottery has gained popularity as a fundraising method in recent years, and it is often considered to be a more honest ...

Reduced matrices of the same size were obtained for 13 connections from both the detailed model and model EC5 (the connection C1 did not use a 2D spring in the EC5 beam-model and was therefore not included in the comparison). A screening of the ratios of the diagonal terms corresponding ...
The maximum relative error in modal frequency is calculated, and a comparison is made with the response surface method. Finally, the 7th, 8th, and 9th order natural frequencies and mode shapes of experimental and simulated modes are compared to validate the accuracy improvement of the finite ...
As can be seen, in comparison to the outcome of the FEM-based optimization, the achieved optimal structural weight using the GNN-based optimization displays a high accuracy with a minimal difference of 0.9%. The GNN-based technique took only 607.1 s for predictions, which included 80.5 s and...
The design data presented in the figure were all derived from the engineering design drawings. Due to space limitations, only the partial comparison results of the pier tops and mid-span areas in a half-span symmetrical structure are presented. In Figure 5, the position of the bar ...
It also offers an insight into design practice in the Ukraine that foreign investors and construction companies may find helpful in the anticipated restoration of the country. Figure 1. Comparison of heating demand with the increase in thermal bridges (Adapted from Ref. [2]). The proportion of ...
GraphSLAM [16] is also used as a comparison for some of the results. During the testing, data were collected from two sources: (1) the on-board camera and (2) the global OptiTrack system. Post-processing software, adapted from AprilTag3 [17] and pupil-apriltags [18], was used to ...
Following the comparison between the CA method and the PCG method in the previous section, the Guyan + CA method can be eliminated first. This section focuses on comparing the Guyan + Epsilon method and Guyan + PCG method, and it compares the ln(Fr) and Mr values obtained using the ...
Figure 7.Comparison of stress time-history at location 1. Figure 8illustrates the stress time-history response of nodes positioned along the chord of the main truss during the temporary member dismantlement process. For the 128 m span, nodes at positions 2, 3, 4, and 5 of the upper chords...
