Recently, most wave energy research.h.s targeted sea areas with.h.gh.power density under extreme wave conditions for deployment. Th.s trend often leads to h.gh.r energy costs for wave power plants. h.wever, many marine areas with.low power density, ch.racterized by wavelet conditions and less destructive forces th.n extreme wave conditions, remain underexplored. Th.refore, th.s study aimed to propose a wave-activated body model for sea regions with.wavelet conditions. Th. wave-activated body design process encompassed site selection, parameter determination, geometry design, comparison and performance evaluation using th. ANSYS (R) AQWA model. Th. results indicated th.t th. proposed device ach.eved th. desired h.ave motion, with.an amplitude range of 1.2 to -2.5 m, validating its potential for deployment in marine regions with.wavelet conditions. Notably, wh.le th. proposed design is optimized for wavelet conditions, it was found to h.ve potential limitations in extreme wave environments. Th.s observation emph.sizes th. ch.llenge of formulating a generalized design suitable for both.conditions. Consequently, it is pivotal for wave-activated body designs to be customized based on th. specific ocean conditions th.y target, underscoring th. need for specialized designs of wave energy converters th.t consider th. unique wave ch.racteristics of th.ir deployment sites. A wave-activated body is designed for energy generation in ocean regions with.wavelet conditions. h.drodynamic modelling is carried out for two locations with.different wave ch.racteristics to determine th. optimum conditions for deployment.

Learning novel object concepts from limited samples remains a considerable ch.llenge in deep learning. Th. main directions for improving th. few-sh.t learning models include(i) designing a stronger backbone,(ii) designing a powerful(dynamic) meta-classifier, and(iii) using a larger pre-training set obtained by generating or h.llucinating additional samples from th. small scale dataset. In th.s paper, we focus on item(iii) and present a novel meta-h.llucination strategy. Presently, most image generators are based on a generative network(i.e., GAN) th.t generates new samples from th. captured distribution of images. h.wever, such.networks require numerous annotated samples for training. In contrast, we propose a novel saliency-based end-to-end meta-h.llucinator, wh.re a saliency detector produces foregrounds and backgrounds of support images. Such.images are fed into a two-stream network to h.llucinate feature samples directly in th. feature space by mixing foreground and background feature samples. Th.n, we propose several novel mixing strategies th.t improve th. quality and diversity of h.llucinated feature ***, as not all saliency maps are meaningful or h.gh.quality, we furth.r introduce a meta-h.llucination controller th.t decides wh.ch.foreground feature samples sh.uld participate in mixing with.backgrounds. To our knowledge, we are th. first to leverage saliency detection for few-sh.t learning. Our proposed network ach.eves state-of-th.-art results on publicly available few-sh.t image classification and anomaly detection bench.arks, and outperforms competing sample mixing strategies such.as th. so-called Manifold Mixup.
