A Malaysian state of Sabah is blessed with natural deep sea water (DSW). The presence of these DSW's offers a potential for OTEC power plant to be installed and operated using warm surface sea water (SSW) as a heat source and the cold DSW as a heat sink. In the operation, the power plant may need to ...
One of the main issues for using autonomous underwater vehicles in fish pen inspections is the pose estimation of the vehicle with respect to the fishnets. In this paper, a novel X-junction detector (Fast-Cross) is proposed, which is able to detect fishnet knots and their topology in camera images. ...
The SEATONOMY methodology is a systematic approach to make efficient the design, development and verification and validation of autonomous systems. The relationship between levels of autonomy (LOA) and availability of communication is an important factor for underwater drones. Underwater autonomous ...
Recent endeavours have focused on the possibility of developing multi-use marine areas that integrate open-ocean aquaculture in conjunction with marine renewable energy device deployment. Advantages of performing mariculture activities within offshore tidal stream farms are manifold, including increased ...
The FP7 funded TROPOS project approach is to develop a modular multi-use platform for use in deep waters, coupling several activities, amongst which aquaculture production and renewable energy conversion, with a focus on the Mediterranean, tropical and sub-tropical regions. In this paper, the environmental ...
The deep ocean water (DOW) which has low temperature and high nutrients will be effective for regenerating subpolar/temperate seaweed bed and aquaculture of those seaweeds. In the present study, a semi-enclosed small fishing port near the pumping facility of DOW in Kume Island of Okinawa in Japan is ...
Information transmission in the marine scenario utilizing wireless communications is unique method that empowering the technology for the evolution of imminent marine-surveillance systems and sensory networks. Under-water wireless sensor network (UWSN) in one of the auspicious technology for marine ...
In this paper the design and realisation of an integrated online water quality monitoring system will be described. The system has been applied specifically to monitor the DO (Dissolved Oxygen) and pH parameters in several shrimp aquaculture centersin Indonesia. The aim was to reduce energy consumption ...
Carrying abundant nutrition, terrigenous freshwater has a great impact on the spatial and temporal heterogeneity of phytoplankton in coastal waters. The present study analyzed the spatial-temporal variations of Chlorophyll-a (Chl-a) concentration under the influence of discharge from the Yangtze River, ...
Background: One of the problems that addicts suffer from is decreased libido. Erectile dysfunction has been reported in men using opioids for treatment of heroin addiction. Objective: The study was performed to investigate the effects of morphine and detoxification with methadone as causes of sexual ...
Radiated underwater noise of a trawler has been measured with the purpose of investigating the characteristics of the radiated noise of fishing vessels in order to understand the relative large variations in catch rates of the vessels that are experienced. In addition to the standard analysis, the investigation ...
Choosing a suitable network interface for Mobile Delay-Tolerant-Network (DTN) is a challenging task. The tested network interface must cope various density variation and analyzed in long time period. Long period network interface simulation in various environment require very long time to finish. In ...
Marine Current Energy Generation (MCEG) is a new technology that can produce emission-free electricity by using the velocity of sea currents. This paper explores possible environmental, social and environmental impacts of MCEG in Indonesia, a developing country that is currently facing a shortage of ...
Crossroads of international issues, maritime domain is facing growing human activities (fishing, transportation, boating…) involving a large spectrum of ships from small sailing boats to super tankers. This increase of maritime mobilities has favored the appearance and generalization of position report ...
A five-year National Science Foundation-funded Research Coordination Network (RCN), the “OceanObs” RCN is currently in its third year. The RCN continues to focus on key issues in both ocean observations and community outreach. A working group has addressed recommendations for improvements in the joint ...
This paper proposes a new approach for a group of robots carrying out a collaborative task to adapt on-line to actuation performance variations among the robots. We consider the problem of multi-robot coverage, where a group of robots has to spread out to cover the environment. We suppose that some ...
This paper deals with the history of Japan's Underwater Robot Competitions and its future prospects. In Japan, an underwater robot festival was first held in October 2006. At present, such competitions take place twice a year in the Tokyo and Kobe/Kita-Kyushu areas. The AUV division sets various missions ...
The knowledge of the impulse response of the propagation channel is required for many underwater applications as communication, sonar detection and localization, marine mammals monitoring, etc. In the context of target classification, this impulse response informs about the relative motion between the ...
Although Indonesia has been rabies-infected since at least the 1880s, some islands remain rabies-free, such as Lombok. However, due to its adjacency to rabies-infected islands such as Bali and Flores, there is considerable risk of a rabies incursion. As part of a rabies risk assessment project, surveys ...
