As manually correcting error in visual interpretation data is both costly and labor intensive, the automated error detection and correction approaches is in need. In this paper, a prototype method is developed to detect and correct errors in visually interpreted landuse data. This method involves image ...
Panchromatic Remote-sensing Instrument for Stereo Mapping 2 (PRISM-2), which will be used for the next high spatial resolution global land observation mission, will extend the capabilities of earlier Advanced Land Observing Satellite (ALOS) missions. PRISM-2 will be able to collect wide-swath (50 km) ...
Recently some types of quasi-circular patchy vegetations have been found and proved by high spatial resolution satellite remote sensing images and field investigations in the Yellow River Delta. In order to facilitate the monitoring of vegetation extension and quantify the mechanism of vegetation patch ...
This study provides the capability of mapping, monitoring distribution and changes of regional mangroves using remote sensing data. The study area located in Mekong delta, Vietnam. Landsat ETM+ and digital elevation model (DEM) were used to enhance the discrimination between mangrove and non-mangrove ...
Vibrio cholerae(V. cholerae) is a component of coastal and estuarine microbial ecosystems, with the copepod species of zooplankton that comprise the aquatic fauna of rivers, bays, estuaries and the open ocean serving as host for the bacterium. There is a remarkably strong association between cholera ...
In this article an attempt is made to study the highly complex and is characterized by high content of organic, inorganic and chromium, suspended solids and dissolved solids present in Tannery waste water. Treatment of tannery waste water is carried out by physical, chemical, biological or the combination ...
According to the development needs of aquaculture modernization, the wireless sensor network (WSN) technology is introduced into the development of aquaculture monitoring system, which can effectively solve the problem of complex work environment, scattered monitoring locations, and high wiring cost ...
There is a lot of expert knowledge in fish disease diagnostic process. Aimed at the drawbacks of expert diagnosis such as low level of intelligence and poor practicality, a new structure of fish disease diagnostic expert system based on neural networks is proposed. The diagnosis system uses the old ...
This paper analyzes the strategic significance of development of the marine economy in Liaoning, and provides an overview of the current development situation. Several restricting factors and countermeasures are elaborated in the development of marine economy in Liaoning, specifically including optimizing ...
Vibriosis is the most prevalent bacterial disease which causes high mortality among aquatic animals. Vibrio anguillarum is one of the main causative agents of Vibriosis. In the present study to control V. anguillarum, ZnO nanoparticles with average size of 50nm were synthesised using varying concentrations ...
In order to steadily speed up the urbanization process, enhance the city image, to promote China's economic and social development and to build up the harmonious society, the employment problem of residents in Villagein-city have to be solved urgently. This paper chooses the employment condition of ...
ABSTRACT In the structural design of bilge keels, hydrodynamic loads may threaten the structural integrity of both the bilge keel and of the hull itself. In the former case, it is the direct load from differential pressure that causes bending and shear at the root of the bilge keel. In the latter it ...
ABSTRACT Based on the drifting Japanese commercial fishing vessel and small container flown out by tsunami of the Great East Japan Earthquake, the tracking simulation of large- and middle-scale drifting objects including leeway effect is performed in the North Pacific with climatology data. The results ...
ABSTRACT Artificial reefs have been utilized throughout the world for many different purposes. The majority of artificial reefs globally are related to fisheries ecology and management. In fact, artificial reefs are capable of attracting and aggregating fishes as well as enhancing the habitats of other ...
ABSTRACT A strip method on ship motions moored along jetty, which employed a singularity distribution method; Green function G=logR was prepared in the author's previous study. Applying to an arbitrary bathymetry around the ship, which includes the shapes of the ship hull, the quay wall and the sea ...
ABSTRACT A computational tool, based on a hybrid model, for the simulation of the coupling between ship motions and liquid sloshing inside ship tanks is considered. A 3D panel method based on the frequency-domain potential-flow theory is used to evaluate the external flow around the ship hull. Hydrodynamic ...
ABSTRACT The present study provides the numerical simulations with the unsteady Reynolds Averaged Navier-Stokes (URANS) methods for the prediction of added resistance performance of KVLCC2 advancing forward in regular waves at Fn=0.142 and Re=4.6×106. Six degrees of freedom (DOF) motion equations based ...
ABSTRACT Wave Hub is a Marine Renewable Energy Installation (MREI) off the southwest peninsular of the UK. Wave Hub's seabed infrastructure, including the main connection unit and 18 km of seabed cable were deployed in 2010. This study assesses the species assemblages present within the Wave Hub development ...
ABSTRACT Much of garbage patches consist of plastics, and most of these plastics are reusable (Werthmann, 2007). Long-lasting plastics that are found in garbage patches contain numerous toxic materials (Teuten et al., 2009). Cleaning up garbage patches involves environmental matters and economic and ...
ABSTRACT Every year, a huge quantity of marine debris is washed up onto Japanese coastal areas, and more than half of the debris is plastic. It has been thought that plastics such as polystyrene or polycarbonate do not thermally decompose at a natural environment temperature. However, a possibility ...
