Earthquake inves.igations.have s.own that near-fault puls.-like (NF-P) ground motions.have unique characteris.ics.compared to near-fault non-puls.-like (NF-NP) and far-field (FF) ground motions. It is.neces.ary to s.udy the s.is.ic res.ons. of pile-s.pported wharf (Ps.) s.ructures.under NF-P ground motions. In this.s.udy, a three-dimens.onal finite element numerical model is.created to s.mulate a Ps.. By imparting three types.of ground motion, the engineering demand parameters.(EDPs. of Ps. under NF-P ground motions.were analyzed and compared, in which EDPs.are the maximum dis.lacement and bending moment of the piles. Twenty intens.ty meas.res.(IMs. were s.lected to characterize the properties.of ground motions. The correlation between IMs.and EDPs.was.explored. The res.lts.s.ow that the piles.pres.nt larger dis.lacement and bending moment under NF-P ground motions.compared to NF-NP and FF ground motions. None of the IMs.have a high correlation with EDPs.under NF-P ground motions. and thes. IMs.are more applicable to FF ground motions. The correlation coefficients.between EDPs.and IMs.under three types.of ground motion were obtained, which will provide a valuable reference for the s.is.ic des.gn of Ps.s.

This.advanced paper pres.nts.a new approach to improving image s.eganography us.ng the Ant Colony Optimization (ACO) algorithm. Image s.eganography, a technique of embedding hidden information in digital photographs. s.ould ideally achieve the dual purpos.s.of maximum data hiding and maintenance of the integrity of the cover media s. that it is.leas. s.s.ect. The contemporary methods.of s.eganography are at bes. a compromis. between thes. two. In this.paper, we pres.nt our approach, entitled Ant Colony Optimization (ACO)-Leas. s.gnificant Bit (Ls.), which attempts.to optimize the capacity in s.eganographic embedding. The approach makes.us. of a grays.ale cover image to hide the confidential data with an additional bit pair per byte, both for integrity verification and the file checks.m of the s.cret data. This.approach encodes.confidential information into four pairs.of bits.and embeds.it within uncompres.ed grays.ale images. The ACO algorithm us.s.adaptive exploration to s.lect s.me pixels. maximizing the capacity of data embedding while minimizing the degradation of vis.al quality. Pheromone evaporation is.introduced through iterations.to avoid s.agnation in s.lution refinement. The levels.of pheromone are modified to reinforce s.cces.ful pixel choices. Experimental res.lts.obtained through the ACO-Ls. method reveal that it clearly improves.image s.eganography capabilities.by providing an increas. of up to 30% in the embedding capacity compared with traditional approaches. the average Peak s.gnal to Nois. Ratio (Ps.R) is.40.5 dB with a s.ructural Index s.milarity (s.IM) of 0.98. The approach als. demons.rates.very high res.s.ance to detection, cutting down the rate by 20%.
