The dispersion and attenuation characteristics of Arctic Ocean guided waves have significant applications in the analysis under-ice acoustic fields inversion parameters ice, water, sediment, seafloor. However, determining complex relationship propagating a damped medium presents challenges. In this study, was modeled as viscoelastic ice-water-sediment-seafloor coupled system. Moreover, spectral method introduced to investigate waves. wave equations boundary conditions were discretized,...
Chitin, the second most abundant biopolymer in nature after cellulose, has a diverse array of applications pharmaceutical, medical, agricultural, textile, cosmetic, wastewater treatment, and food industries. This versatility is attributed to its essential functional properties, including biodegradability, biocompatibility, non-toxicity. The primary source commercial chitin shells crustaceans. However, quantity quality extracted from various crustacean have not yet been systematically...
Provenance and intervention-based techniques have been used to explain surprisingly high or low outcomes of aggregation queries. However, such may miss interesting explanations emerging from data that is not in the provenance. For instance, an unusually number publications a prolific researcher certain venue year can be explained by increased another same year. We present novel approach for explaining outliers queries through counter- balancing. That is, are opposite direction outlier...
The study of transient acoustic wave propagation across the Arctic Ocean ice layer provides theoretical guidance for design trans-ice communication systems. In this study, was modeled as an ice–water composite structure, where and water are regarded elastic solid liquid, respectively. An analytical solution in structure derived using eigenfunction expansion method. Further, numerical procedures were presented used to analyze characteristics layer. results show that waveforms corresponding...
In many data analysis applications there is a need to explain why surprising or interesting result was produced by query. Previous approaches explaining results have directly indirectly relied on provenance, i.e., input tuples contributing the result(s) of interest. However, some information that relevant for an answer may not be contained in provenance. We propose new approach query augmenting provenance with from other related tables database. Using suite optimization techniques, we...
In this demonstration we showcase Cape, a system that explains surprising aggregation outcomes. contrast to previous work, which relies exclusively on provenance, Cape outliers in queries through related the opposite direction provide counterbalance . The foundation of our approach are aggregate regression patterns (ARPs) describe coarse-grained trends data. We define as deviations from such and present an efficient algorithm find counterbalances explaining outliers. demonstration, audience...
This study sampled five plant species and adjoining sediments from the Qi’ao (Zhuhai) Nansha (Guangzhou) coastal wetlands located in Pearl River estuary, South China. The compositions of stable carbon nitrogen isotopes as well content samples were analysed. Differences carbon/nitrogen (C/N) ratio, habitat feature compared between exotic plants (Spartina alterniflora, Sonneratia apetala, Laguncularia racemosa) native mangroves (Aegiceras corniculatum Acrostichum aureum). results showed that...
Software prefetching and hardware-based cache allocation techniques (CAT) have been successfully applied in main-memory database engines to fetch data into before it is needed partition a shared last-level (LLC) prevent concurrent tasks from evicting each others' data. We investigate the interaction of these demonstrate that while single strategy sufficient, combination both only effective if partitioning adapts based on types currently sharing an LLC. present simple, yet effective, scheme...
In many data analysis applications, there is a need to explain why surprising or interesting result was produced by query. Previous approaches explaining results have directly indirectly used provenance (input tuples contributing the result(s) of interest), which limited fact that relevant information for an answer may not be fully contained in provenance. We propose new approach query augmenting with from other related tables database. develop suite optimization techniques, and demonstrate...
Orthogonal frequency-division multiplexing (OFDM) has great application potential in high-speed underwater acoustic communication owing to its high bandwidth utilization efficiency. However, it is challenging realize reliable OFDM shallow-water channels the impacts of multipath propagation, Doppler effect, and ambient ocean noise. In this study, a polar-coded system was developed, Monte Carlo (MC) method for constructing optimal polar codes proposed improve performance system. Several with...
