Globally, economies and marine ecosystems are increasingly dependent on sustainable fisheries management (SFM) to balance social, economic, and conservation needs. The overarching objectives of SFM are to maximize both conservation and socio-economic benefits, while minimizing short-term socio-economic ...
In deep learning, convolutional neural network (CNN) mostly apply common overland images instead of underwater images classifiers. Even though there are few classifiers that have been introduced in marine and aquaculture application, there is still limited sources of the underwater images such as shrimp ...
Simple Summary Sturgeons are species of biological and economic importance. Among them, the beluga sturgeon (Huso huso, Linnaeus, 1758) is the largest freshwater fish and can reach a maximum weight of 1000 kg. Over 80% of existing sturgeon species are endangered, vulnerable, or on the brink of extinction ...
Packaging mainly functions by protecting and preserving its contents. In the case of food packaging, the package protects the contained food product from (i) physical/mechanical damage; (ii) physico-chemical changes due to the effect of light, oxygen, moisture and odors; and (iii) biological changes ...
Coastally distributed dolphin species are vulnerable to a variety of anthropogenic pressures, yet a lack of abundance data often prevents data-driven conservation management strategies from being implemented. We investigated the abundance of Indo-Pacific bottlenose dolphins (Tursiops aduncus) along ...
Climate change is strongly impacting the Arctic environment, leading to rapid sea ice loss. In some sectors, the retreating ice edge is perceived as an opportunity to expand and develop economic activities. Previous studies show this development in the Canadian and Russian Arctic. This paper examines ...
Fish kills, often caused by low levels of dissolved oxygen (DO), involve with complex interactions and dynamics in the environment. In many places the precise cause of massive fish kills remains uncertain due to a lack of continuous water quality monitoring. In this study, we tested if meteorological ...
Enteric redmouth disease caused by the bacterial pathogen Yersinia ruckeri is the main reason for antimicrobial prescription, and a cause of substantial economic losses and decreased animal welfare in aquaculture. Given the importance of the intestinal microbiota in digestion and disease, our aim was ...
Surf-riding and broaching in severe following and quartering seas are vital threats for the safety of fast naval and fishing vessels. Excessive roll motions and even capsizing due to lose of stability can occur under surf-riding and broaching. The rudder and its resulting moments are important for the ...
ABSTRACT The application of Bayesian inference in prediction of meteorological and oceanographic parameters to improve the estimation of sea spray icing in the Arctic region is purposed. Reanalysis data from NOrwegian ReAnalysis 10km (NORA10) during 33 years are applied to evaluate the performance ...
ABSTRACT SCRs have been found to have the advantages of relatively low manufacturing cost and good adaptability of floating platform's motion. For deepwater SCRs in extreme harsh environment, a steel lazy-wave riser has been adopted for reducing vessel payload and to decouple vessel motion in touch ...
ABSTRACT The paper compares the crashworthiness of engine room and cargo hold to assess the safety performance in ship collisions. The external dynamics and the internal mechanics are combined to analyze the structural damages. The finite element simulations of ship collisions account for bow and side ...
ABSTRACT A new method for the integrated modeling of electrified marine propulsion systems has been introduced to predict and identify the best propulsion solution with higher energy efficiency, lower emissions and lifecycle cost. The benefits of advanced hybrid electric propulsion systems with diesel, ...
ABSTRACT A ship moving in water experiences resistances, the major component of which is frictional resistance arising from water viscosity. Therefore, drag-reduction has been an active research field in marine transportation over the last decades. A variety of innovative drag reduction techniques ...
The main attention of present work is to investigate the ability of a adaptive mesh ganeration method in accurate cavitation simulation. A numerical study of the cavitation around NACA66 hydrofoil has been carried out. The simulation results such as cavitation shape, the lift coefficient CL and the ...
ABSTRACT The Seto Inland Sea of Japan has had serious water quality problems as a result of red tide and hypoxia caused by increased phytoplankton growth and, which has led to significant marine life mortality. In recent years, the quality of this sea has significantly improved under the government's ...
ABSTRACT Until 2019 the Rules of Russian Maritime Register of Shipping (RS) had only regulated design ice impact loads on inclined hull sides. These regulations are based on a hydrodynamic model of ship hull/ice interaction. At present large-size vessels operating in the Arctic seas have full hull ...
ABSTRACT The pressure distribution of ship hull can be influenced by a interceptor, which is installed at the stern of ship, to induce a moment for reduing the pitch motion of the ship. However, the phase and amplitude of the moment provided by the interceptor is difficult to determine. This paper ...
ABSTRACT For a hull form optimization design with a relatively large number of design variables, numerous new sample hulls need to be evaluated which cause plenty of computation resource. Therefore, in order to avoid highdimensional sampling, a design-space dimensionality reduction method based on ...
ABSTRACT The tendency of electronic devices, sensors, and integrated circuits aim at applications of ultrahigh frequency, miniaturization, multi-functionality and super integration. One critical issue in the modern microfabrication industry is caused by the uncontrollable Tin-whisker growth on wire ...
